Teaching Philosophy

Teaching Philosophy Kyriaki Chatzikyriakidou
Teaching embodies excellence in communication
One way to spread ideas is the process of teaching, either students in a University or the public
in our society. Teaching embodies excellence in communication. It enfolds discussion by the use
of linguistic and practical skills and the result of it: understanding. Understanding brings easiness
in our lives and magnifies the interest that might exist for specific concepts. With the passing of
time, this interest is transformed into mature knowledge and communication is advanced into
teaching.
Student-centered teaching approaches
Today, there is evidence that active learning and student-centered teaching approaches should
be used in the classroom. For instance, in Microbiology, the most challenging part is the “unseen
world” of microorganisms that students need to see in order to completely perceive and the use
of microscopes, is a great way to succeed this. It has always been of my interest to be able to
imagine what the words on a book’s page try to help us comprehend. From a holistic point of
view, the combination of lecture and student interaction or theory and practice, usually at a
cellular level will excite students and offer them the opportunity to actively participate in class
activities, while exploring their own potential as future scientists.
Knowledge is to be shared
The cognitive path of knowledge building in an individual can be seen as a system of smaller
developmental paths that sometimes, somewhere will merge and start over creating new paths.
This happens for both the students and the teachers. However, it is the teacher’s responsibility
to assess students’ progress of learning and also constantly examine whether the learning
outcomes successfully meet with the learning goals and there is alignment of the teaching plan.
Majoring in Biological Sciences throughout my undergraduate as well as graduate studies, I have
realized the importance of teaching in this particular scientific field. My inclination towards
microbiology and specifically food-borne pathogenic microorganisms has always supported and
will keep supporting my desire to spread this type of knowledge. Every student is a unique and
complex learner, so I would like to introduce students into Biology/Microbiology courses by
using both individual and group projects, so I can cover as many of their learning needs as
possible. My teaching assistant experience in UW–Madison covers a broad spectrum of classes-
from large lab sections to small discussion-based courses, which I mostly had the chance to lead
solo, as the only instructor present in classroom. Furthermore, my experience as a teaching
fellow of the UW-HHMI program, introduced me into scientific teaching methods as well as
educational research background information and questions that need to be investigated and
which I am currently taking this information a step further in my career, with a M.Sc. degree in
Curriculum and Instruction.
Mentoring Philosophy

Mentoring Philosophy Kyriaki Chatzikyriakidou
Unique mentoring relationships
The relationship between a mentor and a mentee can be seen as similar to the one
between a parent and a child. Mentor is a persona that offers advice, encourage the mentee to
pursue his/her dreams and most importantly to construct a career pathway that the mentee
would like to follow. In order for the mentor to be able to offer the above-mentioned support,
he/she needs to have acquired some previous skills as well as experience. Although the mentor
has to be an expert in these characteristics, at the same time he/she will continue learning new
mentoring approaches along with the mentee throughout each and every mentoring
relationship. In my opinion, mentoring also needs patience exercised from both sides, the
mentor and the mentee, and at the same time persistence in finding what the mentee’s subject
of true interest is, while keeping in mind that the mentor will guide this individual’s personal
quest.
As a graduate student who mentored younger undergraduates in UW-Madison, it was
enlightening for me to recognize and comprehend these aspects of mentoring. Coming from a
different cultural and background training, than my mentees in UW-Madison, was my initial
incentive to try to build successful mentoring relationships. Addressing diversity in
communication patterns or learning styles, is something that cannot be successfully met without
realizing that we all carry a unique background which shapes our learning, thinking as well as
communicating processes. In my opinion, these differences should be taken as opportunities for
further personal development and academic growth of the mentee, rather than as a hindrance. I
believe, this is the first step that needs to be established between a mentor and a mentee, prior
to any type of scientific training, either theoretical or practical.
You learn something the best, when you teach it
As a post-doc fellow, I had the opportunity to facilitate discussions around these aspects
of mentoring with a group of undergraduates, majoring in biological disciplines, where they
were taught how to be peer-mentors in a biology course, while co-facilitating with the main
instructor. As the saying goes -You learn something the best, when you teach it-, it very well
applies to me during my interaction with the students in this course, called “Entering
Mentoring”, when my ideas regarding mentoring were further advanced and my interest in
supervising and mentoring students was solidified.
I would like to draw on my previous experiences and continue learning the art of
successful mentoring, not only as an instructor, but also as a person in any biology-related
environment that I may have the chance to participate in.
Everyone needs to be taught or at least be aspired by someone who is in the same
career pathway that they wish to follow. We all need a mentor in our lives, not only for our
careers but also for development of our own ideas, opinions and beliefs.

1ST TEACHING ARTIFACT
This artifact was developed as part of my scientific teaching training, through the
Howard Hughes Medical Institute (HHMI) Teaching Fellows program at University of
Wisconsin–Madison in 2011-2012.
The training program incorporated two main elements:
a) Development of a teaching unit during Fall semester – in my case for the course
“Critical Analyses in Microbiology” (Micro 305). In brief, in this course students
read a research paper every week and discuss its hypothesis and results. The
course aims to develop students’ critical thinking in microbiology research. This
unit’s research paper was “Bacterial charity work leads to population-wide
resistance. Lee H., Molla M., Cantor C. and Collins J. 2010. Nature vol. 467 pp. 82-
85.”
b) Incorporation of this teaching unit in course’s syllabus and facilitation of teaching
the complete syllabus during Spring semester.
The artifact, presented here, is related to (part a) the development of the teaching unit.
The main elements of scientific teaching were incorporated into this teaching unit and
the process is shown in steps.

Antibiotic resistance in bacterial populations
as a result of their social behavior
(Syllabus title: “Bacterial antibiotic resistance and their social behavior”)
Outline
- A 10-minute presentation on antibiotic resistance and introduction to the assigned paper
- 30 minutes of interactive activities – group work and answering homework questions
- Spend the last 10 minutes or less discussing about diseases caused by antibiotic resistant
cells and ways to cure them
Introduction
This teachable unit will educate students about antibiotic resistance in bacterial
populations for a total teaching time of 50 minutes. The level of this class is
undergraduate/graduate, taking into consideration that the majority of the students are
expected to be undergraduate students, majoring in Microbiology or related Sciences.
The design of this teachable unit uses the backward design, where learning goals and
outcomes are first selected and then student assessment is aligned to these learning goals
through the design of the activities.
Learning goals and outcomes
The learning goals described below were formed based on two fundamental questions:
1) how do the learning goals represent the nature of Science and concepts related to
antibiotic resistance?
2) what will students know, understand, and be able to do at the end of the unit?

Each activity is built on all the previous ones. In order for students to fully comprehend
antibiotic resistance in bacterial populations, activities and assessments have been designed
throughout all Bloom’s taxonomy levels. Table 5.4 describes each of these levels.
Assessment and evaluation
The assessment and evaluation are responsible for providing both student and
instructor the information, whether or not students learned to think critically and gauge their
own learning. The assessment part was developed based on table 5.4, which provides a
comparison between learning goals and outcomes of this teachable unit.
At the end of every class, the assignments will be collected by the instructor, corrected,
and returned back to students during the next class. In this way an individual feedback will be
provided and each student will be able to monitor his/her own progress. The instructor will
collect data about student’s progress in order to verify that the primary learning goal, meaning
the ability of students to read and analyze research papers, is met. (This instructor took this

Activities
The activities can be categorized into two groups: homework questions and mini-
lectures given by the instructor. The questions will include low order and high order critical
thinking skills, which will be first, completed by students as homework and then discussed in
class. Discussion will be composed of small group brainstorming as well as whole class
discussion. Question 4 will also include a 1-minute presentation of groups of students and a
mini-talk by the instructor.

Scientific teaching
Alignment
Alignment between learning goals and outcomes is mediated by the feedback provided to
students, as part of the assessment section of this teaching unit.
Active learning
During the duration of the semester, students will have the chance to talk with each
other or even speak in front of class and share their opinion. Every behavior is welcomed, as
long as is not offensive or unfair to the rest of the class.
Bacterial social behavior is an impactful scientific topic, as it affects our own health. It
can provide students the opportunity to think about future research on this research field.
During the group work, students will have the opportunity to collaborate with others and form
their ideas. The instructor is advised to elaborate on information that could arouse students’
curiosity.
Diversity and collaboration
UW-Madison classes are usually made of an heterogeneous mix of cultures and nationalities.
One way to ensure equality in a class like this one, is to shuffle students every week, so no
particular sitting patterns get strictly established. In this way, every student will have the chance
to talk to the majority, if not all, of the students. (other ideas from future instructors are
welcomed, as long as they serve the purpose of engaging students with fair and transparent
intentions). Classes are made not only to educate people, but also to cultivate our behavior
towards others. Diversity comes as a gift for international colleges, like UW – Madison, and for
this reason, instructors should take advantage of this and use it to broaden their student’s
cultural and subsequently learning horizons.

Reflection “Critical Analyses in Microbiology” (Micro 305) is a discussion-based course aiming to help
students develop their critical thinking skills by reading various research papers. Each week
students complete homework questions and participate in various in-class activities, along with
discussing the homework questions.
As a participant in the HHMI Teaching Fellows program in UW-Madison, I had to design a
teaching unit for Micro 305, following the scientific teaching framework (Scientific Teaching, Jo
Handelsman et al.). The main axis of this framework is the alignment of learning goals with
learning outcomes and assessing whether this alignment was successful. The development of
this teaching unit, took place during Fall semester of year 2011, while being instructed about
scientific teaching and presenting our work for in-class peer-review. In addition, all teaching
fellows of Micro 305 were coordinated by Professor Yu, who was the main instructor of this
course.
The learning outcomes were designed based on the six levels of Bloom’s taxonomy on cognitive
skills and I purposefully chose the low-order levels for designing homework questions, assuming
that students will be able to answer them on their own. On the other hand, analysis and
evaluation levels (high-order cognition) were used for designing the in-class activities, which are
harder for students to think on their own, but with interaction and discussion with peers, they
can have better chances on answering them. Furthermore, the class size of my section was
relatively small (<10 students) and this gave me plenty of time to interact with every student.
Although, the design of a complete teaching unit was challenging at first, this was a great first
teaching experience for me and an opportunity to acquire an immense amount of knowledge
regarding scientific teaching. The goals-outcomes alignment is vital part of teaching, as it
provides the instructor with a clear teaching plan, adaptable to modifications that may be
needed due to class pace. Critical thinking is a very important skill in any scientific field, thus
students need to acquire it as early as possible in their undergraduate studies training. Critical
Analyses in Microbiology is a course made to serve this purpose and I am glad I had the chance
to be the instructor for an academic semester.
Designing and teaching this unit and course overall, created the interest in conducting a small
education research study, presented next, as the second teaching artifact of this portfolio.

Applying Bloom’s taxonomy theory to advance critical thinking of
undergraduate biology students
K. Chatzikyriakidou
Wisconsin Program for Scientific Teaching, Institute for Biology Education, 2012.
Abstract It is known that introductory Microbiology classes enhance the development of low-order
cognitive skills, however, development of high order cognitive skills is considered challenging
due to limited time and wide variety of material to be covered. “Critical analyses in
Microbiology” is a discussion-based course, offering students the opportunity to critically
analyze microbiology research data. The aim of this study was to investigate whether student’s
ability to critically think of experimental data could improve when students individually
categorize homework questions into the six Bloom’s cognitive levels. As far as the applicability
of these activities, they were both successfully completed without consuming a lot of class time
and without interrupting the general teaching plan. Although no pertinent trend was found in
the data collected, results showed that students were better able to recognize low-order
cognitive levels questions than high-order levels ones, which seemed to align with the results of
the short-time assessment activity as well. Further research is needed to conclude these results
in similar introductory Microbiology courses with higher numbers of participants and repeats of
this methodology.
Introduction In 1950’s the American educator Benjamin Bloom developed a classification of human
cognitive levels, known as Bloom’s taxonomy of the cognitive domain (2). The levels increase in
complexity and critical thinking is accomplished when a student is able to think at cognitive
levels 3 to 6 (application, analysis, synthesis and evaluation). Through application of previous
knowledge to new context, analysis and synthesis of ideas when problem-solving and evaluation
of the newly formed knowledge, students are able to think critically of scientific information, not
only in biology major, but in any scientific discipline. Today Bloom’s taxonomy is used by biology
instructors during syllabus writing and course learning goals development (1,3,4). Although
students have access to a course’s syllabus and learning goals, it can not be taken for granted
that students recognize which cognitive level they have mastered at the beginning of a course
and what is the ultimate goal after completing a course. In literature, there is no information on
2nd Artifact
12 | P a g e
the application of Bloom’s taxonomy in a student-centered instructional approach, where
students could potentially rank themselves on Bloom’s taxonomy and self-evaluate their
learning experience.
Majority of undergraduate biology courses are taught in traditional ways with lectures
and exam questions mainly focusing on remembering and understanding of scientific facts, thus
low-order cognitive skills. In University of Wisconsin – Madison, the course “Critical analyses in
Microbiology” has been developed to address this issue, as it has the aim to advance student
cognition to these high-order cognitive skills through discussions on research papers with their
peers. Since the learning environment was set for advancement of student cognitive skills, this
research study was designed to examine whether student’s ability to critically think of
experimental data could improve when students individually categorize homework questions
into the six Bloom’s cognitive levels.
Methodology
Course description
“Critical Analyses in Microbiology” is a discussion-based course aiming to develop
critical thinking skills of undergraduate biology students. It consists of 15 teachable units, each
one taught each week, following an increasing level of difficulty in analyzing research data. The
teaching units were built by participants of Teaching Fellows program following the scientific
teaching framework (5,6). Students read different research papers and answer various
questions, regarding the hypotheses and findings of the research study, either as homework or
as in-class activities.
Bloom’s taxonomy activity
The researcher provided students with two identical Bloom’s taxonomy forms to fill,
along with a brief description of the Bloom’s taxonomy and a handout, constructed by the
researcher. Each form had a table made of five columns in total, each one representing the
course week and specific homework questions of each week’s material. Each line of the table
represented one of the six Bloom’s taxonomy levels. For practical reasons, one form included all
the even course week numbers and the other included all the odd course week numbers, so that
the researcher could keep one of the forms, while students could keep the other one. The
homework questions were chosen based on the Bloom’s taxonomy level that the researcher
thought they belong to. Each week, students were asked to choose for each question listed on
2nd Artifact
13 | P a g e
the table, what Bloom’s taxonomy level they thought the question belonged to, allowing them
to choose more than one levels per question if they thought so. This process was repeated for
nine weeks and students had a week to complete and return the form.
Short-time in-class written assessment
The activity consisted of two unannounced mini-tests at two time intervals; one during
the first quarter and one during the third quarter of the course. Each test was an excerpt of a
scientific paper, including an experimental aim, a brief experimental design and the key findings
of the experiment. The excerpt was chosen from a scientific paper that students had to read as
part of their homework. This assessment happened in two different orders: one excerpt was
introduced to the class as homework and then as a short-time written test (during third
quarter), while the other excerpt was first seen in-class as part of the short-time written test
and then as a homework (during first quarter). The students were asked to read this excerpt and
then briefly (1-2 sentences) answer two questions. The first question “What did the authors
want to study?” (why? question) addressed the aim/hypothesis of the experiment, while the
second question “What did the authors find at the end?“ (what? question) addressed the
findings. The time for the in-class activity was limited to 5 minutes. Both homework and in-class
responses were graded on a pass/fail basis.
Results and Discussion The main goal of this study was to test whether students get better at understanding
what the hypothesis of an experiment is as well as analyzing research data. As the instructor and
researcher of this class and study, I wanted to let students know what “high-order cognitive
skills” means, while trying to advance their critical thinking in microbiology research. Designing a
Bloom’s taxonomy activity, as described above, was a simple way to introduce students to this
cognition theory. With the short-time in-class written assessment, I tested students’ ability to
analyze a research paper, with or without having a memory of it.
Results from the Bloom’s taxonomy activity showed that students were able to
successfully categorize most of the low-order cognitive level questions of their homework,
during the 9-week period, with minor fluctuations from the correct answers, ranging from 1 to 3
responses (Figure 1). However, the responses for the high-order cognitive level questions varied
throughout the course and a high number of low-order cognitive level categorization was
received as well, ranging from 1 to 6 responses (Figure 2). Although feedback was purposefully
2nd Artifact
14 | P a g e
restricted, it is possible that students’ responses could have been more aligned to the correct
answers if more explanation was given regarding Bloom’s taxonomy levels throughout the
course.
An improvement in successfully categorizing the high-order cognitive level questions
was seen in the fifth week (week 7 in graph) of the study, but there was no persistent trend. An
explanation of this observation could be the fact that in order for someone to answer a question
that belongs to the levels of application, evaluation, synthesis or analysis, low-order cognitive
skills are also required - remembering and understanding facts. As a result, the students were
probably not able to identify these high-order cognitive level parts in these questions. In other
words, it is valid to say that students were not able or unsure how to categorize these high-
order cognitive level parts of these questions, beyond the low-order cognitive level ones with
which they were familiar.
Figure 1. Successful (color) and unsuccessful (grey shade) student responses for each
low-order cognitive level question per course week.
Table 1. Results of short-time in-class written assessment
In conclusion, a progress towards high-order cognitive skills was obvious in this class.
Incorporating short-time activities into undergraduate biology courses, such as the ones
presented here, can have a positive effect on students’ high-order cognitive skills development
and also inform the instructor about the course itself, regarding learning goals and outcomes.

Reflection
“Critical Analyses in Microbiology” is a discussion-based course aiming to help students develop
their critical thinking skills by reading different research papers each week and answering
questions, either as homework or as in-class activities. The study, presented above, was
conducted during my first teaching experience in an undergraduate Microbiology course (300-
level) and it was an optional part of my scientific teaching training during the Teaching Fellows
program at UW – Madison.
The main aspect of this research study was to examine the critical thinking development of
students as they get informed about Bloom’s taxonomy cognition theory. Designing a Bloom’s
taxonomy activity, as described above, was a simple way to introduce students to this
information. With the short-time in-class written assessment, I aimed testing students’ ability to
analyze a piece of a research paper that may or may not have previously seen as their
homework assignment.
In brief, I concluded that undergraduate students are able to comprehend and remember
information, but they have difficulty in recognizing and engaging in high-order cognitive
thinking, especially under time pressure. Critical thinking can only be developed with practice
and classes such as “Critical Analyses in Microbiology” are great learning environment for
undergraduate students to succeed this. There are a few limitations in the study design that do
not allow solid conclusions to be drawn at this point. For example, the sample size of this study
was rather small (n=8), thus further research is needed to verify these findings. Furthermore,
providing more feedback to students throughout the course could have yielded more positive
results. If I taught the same course again, I would give students more information on Bloom’s
taxonomy, as well as providing them with examples of homework questions belonging to each
Bloom’s category. I would also test more research papers, during the short-time in-class
assessment, in order to cancel out the effect of content in excerpt that can be a limiting factor in
this study. Finally, I would like to look at these results as an internal evaluation of the courses
that aim to promote students’ critical thinking. Activities similar to the ones presented can be
used as an assessment tool and verify the learning objectives of a course.
This was my first experience in conducting and presenting a biology education research study
and it helped me discover my personal interests in this area, which subsequently lead to a post-
doc position in biology education in WISCIENCE in 2015. Classes that focus on critical thinking
are necessary in any STEM discipline, as this is the major characteristic of scientific thinking.

TEACHING AS RESEARCH
INTERNSHIP PROJECT REPORT
Teaching as research can be summarized as a circular process in this order: 1. Plan
teaching 2. Conduct this plan and collect data 3. Analyze the data-Draw conclusions, 4.
Make changes-Plan new teaching. When teaching as research is transparent to students,
it can be an alternate way for students to comprehend the scientific way of thinking that
need to have as future scientists or, otherwise stated, advance their high-order
cognitive skills.
This report has been produced as the core project of my Delta internship, fulfilling the
requirements towards a Delta Certificate in Teaching and Learning.

Advancing the 4C's (Critical thinking, Collaboration, Communication, Creativity)
through social bookmarking and collaborative discussions in an undergraduate physics class.
“How has your internship experience influenced your understanding of teaching-as-research, learning-through-diversity and learning communities? Teaching-as-Research
Teaching as research prepares the educator to scrutinize the teaching plan, while
considering learning goals and how students will achieve these goals throughout the class. It
could be summarized as: 1. Plan teaching 2. Conduct this plan and collect data 3. Analyze the
data-Draw conclusions, 4. Make changes-Plan new teaching. In Physics 241, the class which I
conducted my DELTA internship at, the primary teaching plan was modified by the main
instructor to contain innovative teaching elements, such as online bookmarking activities and
weekly discussions in a well-equipped with technology devices classroom. The purpose of
adding these new elements to the course was to expose students to an environment that could
advance their collaboration, communication and critical thinking skills. The primary investigator
and I planned out the research question we wanted to investigate with the primary hypothesis
that participation in the online bookmarking activity will advance students’ critical thinking.
Learning-through-Diversity As an international student, I wholeheartedly believe that learning can be enhanced
through diversity and this can entail different nationalities, educational backgrounds and
personal beliefs and opinions. Although majority of the Physics 241 class was US citizens, they
were exposed to different learning styles and ways of thinking among their peers, especially
those who regularly participated in the weekly discussions. Students had to work as groups
around a pod exchanging ideas or problem-solving regarding physics homework questions. In
the future, as a potential instructor, I would like to include the element of diversity in a course,
for example, by inviting international guest speakers who could ignite learning through a
different than mine perspective and foster the broadening of students’ horizons.
Learning Communities Science can be seen as an interdisciplinary and dynamic form of existence, and an
individual can be seen as exactly the same. However, for changes and improvement to happen,
interactions are needed and these interactions are best achieved inside communities. All DELTA
classes are structured with learning communities and I personally had many ideas formed during
our meetings, that otherwise wouldn’t have. In Physics 241, communities were formed every
week during the group discussions, as well as online communities (Diigo), via online discussions
on physics research papers. Students participated in both activities and I witnessed the fact that
these communities were contributory to students’ learning. Literature also supports the fact
that group discussions and interactive activities with peers are impactful teaching approaches
for an individual’s learning development path and I also wish to put an effort in implementing
them in classes that I may be the instructor of.

APPENDIX I Instructional materials for teaching unit Bacterial “Social” Behavior Homework
(week 5 in Micro 305)
Assigned reading
Bacterial charity work leads to population-wide resistance. Lee H., Molla M., Cantor C. and
Collins J. 2010. Nature vol. 467 pp. 82-85.
Homework questions
One week before this class, students will be asked to read the paper and answer the following
questions:
Homework begins by asking students a low order cognitive level (Bloom’s taxonomy) question:
The authors of this paper proceeded on their research based on their findings of previous trials.
There is a series of 6-7 individual experiments (trials) that the authors completed for two
different antibiotics.
Provide the hypothesis and the main result for each of these experiments (pp. 82-83).
Figure Hypothesis Main result

2b
2d
33 | P a g e
The next step is to move on towards high order cognitive levels (Bloom’s taxonomy) questions:
After an in-class discussion of question 1, students will work as groups and then as a class to
answer additional homework questions related to the assigned reading and specifically the
figures of the paper. Students are required to complete these questions before class, in order to
help their understanding and interpretation of experimental data. Questions are provided
below:
2) Study figure 1 of the paper. This figure presents the results of the first in series
experiment that the authors conducted. Describe in few sentences what was found and
is presented in 1b?
3) a) In figure 2b, describe the behavior of c10,6 and c10,12.
b) Why the mutant strain c10,12∆tnaA grows more under antibiotic stress, if it is unable to
produce indole (figure 2d)?
4) Discuss in groups of 3-4 students the implication of these findings on the treatment of a
disease when antibiotics are provided to the patient. Discuss specifically if the disease
will be curable when HRI and LRI strains are present at the infected area of the patient.
What experiments would you design in order to test your hypothesis?
You will be given 1 minute at the end to present your idea.
5) Study figure 1 of the paper. This figure presents the results of the first in the series of
experiments that the authors conducted. Describe in two sentences what was found
and presented in 1b?
6) a) In figure 2b, describe the behavior of c10,6 and c10,12.
c) Why does the mutant strain c10,12∆tnaA grow more under antibiotic stress, if it is
unable to produce indole (figure 2d)?

In class activity
We know that bacteria work together by using a well-studied communication system called
Quorum Sensing (QS). During infection, bacteria talk to each other using QS to coordinate the
release of toxins.
Last year researchers from University of Nottingham presented at the Society for General
Microbiology's autumn meeting the use of bacteria defective in QS that can benefit from 'opting
out' of toxin production by Staphylococcus aureus during infection of waxworms. As a result the
overall severity of infection is reduced as fewer toxins are produced.
Discuss in groups of 3-4 students how the reduction of severity is mediated in this infection.
What experiment(s) would you design in order to test your hypothesis? What are the
implications of these findings on the treatment of a disease when antibiotics are provided to the
patient?
You will be given 1 minute at the end to present your idea.
