ABSTRACT

New teaching methods reach geographically dispersed students with advances in Distance Education. Capabilities

include a new "Hybrid" teaching method with an instructor in a classroom and a live WebEx simulcast for remote

students. Our Distance Education Geometric and Physical Optics courses include Hands-On Optics experiments. Low

cost laboratory kits have been developed and YouTube type video recordings of the instructor using these tools guide the

students through their labs. A weekly "Office Hour" has been developed using WebEx and a Live Webcam the instructor

uses to display his live writings from his notebook for answering students' questions.

Keywords: Optics education, lens design, optical system design, optomechanical design, optical instrument design,

optical engineering education, hands-on optics, hybrid teaching methods, on-line optics labs.

1. INTRODUCTION

Two years ago we reported on this new program1 of optical engineering and instrument design at the

University of California Irvine Extension. At that time we had transitioned from an earlier program

at Irvine Valley College’s Advanced Technology and Education Park. Here we will describe the

motivation for the new teaching methods now in use in these programs and we will discuss them in

some detail. We will also provide an update on the programs since 2010, mention some of the recent

successes and chart the path for future development.

2. UPDATE FROM 2010

Before beginning the update from 2010, we mention that in the previous report1, we provided a

program overview that centered on a Venn diagram, a program curriculum including required and

elective courses and the then current course offerings. Here we will refer the reader back to that

paper for those details and the program website for current offerings and programmatic details. One

on-line tool we use as a method to introduce potential students to our programs is the Webinar. This

can be seen on the homepage of the program website and has been very helpful in allowing

individuals to learn how our programs and courses can help them with their educational goals and

objectives and learn about new teaching methods we are using.

The main updates from 2010 center around the new instructors we have hired and the new teaching

methods we are using. This has come about in a large part because of the extensive support from the

UC Irvine Extension staff and most importantly their Instructional Technology staff and Distance

Learning Center (DLC). Other updates include the changes in demographics of our students and the

fact that we now have a number of students who have taken and passed enough courses to receive

their Certificate in either our Optical Engineering program or our Optical Instrument Design

program.

The new instructors include Scott Rowe, Joshua Jo, Donn Silberman, Charles Vice and beginning in

September 2012, Keith Kasunic. Scott has taught our Optical Instrument Design course, Joshua is

teaching our Introductory and Advanced Lens Design courses, Donn is teaching our Geometric and

Physical Optics courses, Charles and Scott are teaching Optomechanical Component Design and

Keith will be teaching a new course titled, ‘Optomechanical Systems Engineering.’ We are also in

the process of hiring new instructors for other current and future courses and will mention that in the

last section of this paper.

We had students receive their certificates in Optical Engineering (8) and Optical Instrument Design

(2) in June 2012 and more will be receiving them on an ongoing basis each quarter; as they apply for

candidacy and complete their requirements.

3. NEW HYBRID TEACHING METHODS

In this section we will first discuss the motivations for these new methods. The primary motivation

is to reach more students in geographically dispersed areas. Other important motivations include

having the lectures and live student/instructor interactions recorded for student review after each

class period or office hour is over. This has proven to be very helpful to students, as this material

tends to be very technical and detailed and students may miss key points during the lectures.

Reaching geographically dispersed students, was necessitated due to the large geographic area

covered by Southern California and the traffic congestion preventing potential students from

enrolling. Even though we did and continue to have students who drive up to 1 hour each way to

attend courses at the UC Irvine campuses; we still viewed this as a major challenge.

Even in So. Cal. the traffic can discourage potential students for attending live classes. Typical drive time in traffic can be 1+ hrs

After our first year of courses, we approached the UC Irvine Extension Instructional Technology and

Distance Learning Center staff and asked if we could try a new Hybrid Teaching method. UC Irvine

Extension had an extensive On-Line Distance Education capability, but had never offered a course

where the instructor was in the classroom with some students, while other students were live on-line

via WebEx. The main question we had to answer was: Why record the live lectures? The answers

we found were:

– Instructors move through complex course material quickly and sometimes it is

challenging for students to keep up.

– Students ask questions / instructors to provide answers, and sometimes this goes too

quick for adequate note taking

– Being able to review the lectures improves the students’ ability to comprehend and

retain the course material.

– Allows instructors to focus time on direct interaction with students (where a majority

of the learning takes place)

– Gives students the ability to stop and replay sections of the lectures and office hour

interactions as needed

Then the next question was: How many more students could we reach using these new methods?

The answer is provided in Figure 2 below, where we see a recent map of students enrolled, including

students near Toronto, Boston, Seattle and in Israel. Our Introduction to Lens Design course last fall

had about 10 students from outside Southern California. We believe these new teaching methods

will continue to attract students from many more diverse locations from around the world.

4. NEW HYBRID TEACHING TOOLS

The new hybrid teaching tools includes UC Irvine Extension WebEx Service, Webcams, Extensive

IT support from UC Irvine Extension’s Instructional Technology and Distance Learning Center staff

along with Network licenses for optical and mechanical software tools.

An example of retrieving recorded lectures from the UC Irvine Extension WebEx Service is

shown in Figure 3 below.

This screen shot shows how a student can retrieve and review a recorded lecture from throughout the

course. This can assist the students in recalling information delivered during the course lectures and

includes the slides the instructor was showing, his/her audio discussion and any other information,

like student questions and instructor answers that were recorded during the live lecture.

In addition, Webcams video and audio that were used for various purposes were also recorded and

we will discuss this in more detail in a later section in this paper.

One of the main reasons for our successes with these programs and the new teaching methods has

been the outstanding support from the UC Irvine Extension Instructional Technology and Distance

Learning Center staff. In addition to the technology they offer students and instructors, they offer

extensive training programs for instructors and complete on-line support for both students and

instructors. They also have well trained staff available live on the phone and through live chat lines

at the Student Services and the IT Departments. Typically, an IT staff member will be on-line at the

beginning of each session to make sure all is well; then they sign off.

The screen shot in Figure 4 shows the home web page for the UC Irvine Extension Instructional

Technology services. Here we see that they have a particular Computer Lab Location which is an

excellent resource we used during our first experiments with the Hybrid Teaching Tools. Each

student who came to the classroom for any of our Optical Engineering required core courses had a

PC to use on the desk and they could also use their personal laptop through the UC Irvine WiFi

system. This enabled the students in the classroom to act as eyes and ears to assist the remote

students and the instructor make sure the remote students could interact with the instructor and the

other students. This was a very important development in breaking the barriers and helped us begin

to use all the advanced information technology tools the school has to offer.

Regarding working with network licenses from optical and mechanical software vendors, we began

using Zemax Lens Design Software tools and have had an excellent ongoing working relationship

with their customer support team. Combining this to the UC Irvine Extension IT department staff,

the students and instructors have had a pretty much trouble free experience (we did have a learning

curve in the first year, but we are now over that). We have also used SolidWorks Students Edition

and have not had trouble with that, although we have had much less experience to date with this

portion of our program. Recently, we have introduced our Geometric and Physical Optics students

to OSLO and CODE V and will be having our students use these and other software tools going

forward. We will touch on this again in the final section of this paper.

5. NEW ON-LINE TEACHING METHODS

New on-line teaching methods are and have been used in our Introduction and Advanced Lens

Design courses and our Physical and Geometric Optics courses. These methods are also scheduled

to be used in our new Optomechanical Systems Engineering course and will be used in other courses

as well.

Our Geometric and Physical Optics courses are delivered through using the following methods:

Chapter 5 Lab Exercises

The screen shot shown in Figure 5 of the home web page for the Geometric Optics course shows just

the beginning of what the students and instructors see when they log into their On-Line course. The

Moodle Learning Management Systems or LMS provides a strong framework for learning for the

students and valuable and easy-to-use set of tools for course design and delivery for the instructor.

Tools within Moodle allow the instructor to design the course using a variety of student activities,

assignments and resources as mentioned above for the Geometric and Physical Optic courses and

discussed below for the Introductory and Advanced Lens design courses. Each of these activities or

resources has an easily recognizable icon so students quickly recognize what they are being asked to

do during each week of the course (see fig 7 below). Other features of the LMS system is its ability

to automatically grade multiple choice quizzes and accept (via a simple website upload) and track

assignments submitted by students. The system makes it easy for instructors to grade assignment and

quizzes and provide student feedback immediately. Readers who are interested in learning more

details about this “Moodle Shell” should contact the authors for a guest pass to one of our courses.

Recorded lectures are available for students to view either on their personal computers (PCs) or on

their SmartPhones. This provides the students the capability of reviewing their lectures while they

may be commuting or waiting around while traveling (airports, buses and trains.) In Figure 7

examples of the links to the Flash and SmartPhone recordings are shown. Also is an example of the

Hands-On Lab work assignment, some supplemental pdf files and the link to upload the weekly

homework and labwork assignments

A special web page was set up on the web site of the Optical Society of Southern California (with

links from the official UC Irvine Extension on-line registration web page for this course) that details

the Hands-On Lab equipment that is required for this Geometric Optics course. This was done to

allow the instructor flexibility since he did not have access to the registration web page.

An example of a page of a student’s lab work report is shown in Figure 9. Here, an experimental set

up is shown where the student has a two (2) lens system set up on a low cost optics bench made up

of a wood meter stick and metal lens and screen holders. The USAF target (object) is illuminate

from behind and the image is evaluated on the screen. The numerical parameters are also shown on

this page by the student.

A main point of this paper is to demonstrate the success of including this Hands-On Lab requirement

in an On-Line Distance Education course in Geometric Optics. Similar required experiments were

developed and implemented for the Physical Optics course using low cost diffraction gratings,

polarizers, light sources and detectors.

As mentioned earlier, weekly live WebEx Office Hours are used to provide student / instructor

interactions and those are also recorded for later review by the students as needed. Typically, each

week includes ~1.5 – 2 hours of recorded lectures and 1 – 1.5 hours of live WebEx Office Hours.

An example of a student viewing of a recorded WebEx Office hour is shown in Figure 10. The

instructor has the slide stack up on the screen as the students ask questions about the lecture. All of

the students can interact live on-line in this format, with each other and the instructor. Many times,

the instructor allows the students to answer each others’ questions in an on-line seminar format.

Using industry standard optical design software to demonstrate lens design concepts and theory

discussed in an earlier section of the recorded lecture, the instructor uses the WebCam to draw by

hand the concept of the lens system, in this case how to design from a simple plane parallel plate

(PPP) to the complicated triplet in a minute with the industrial standard optical design software.

Fig. 11. Screen shot from recorded lecture from the Advanced Lens Design course showing

the concept of the Triplet design with the industry standard optical design software and the use

of the WebCam.

6. FUTURE DEVELOPMENTS

Since these programs began in 2009, we have made many advances in the teaching methods used.

As of this report we are working on:

• Adding more new instructors including two who have been involved professional optical

engineering training for many years.

• Continuing to offer more courses, including:

– Introduction to Lasers

– Introduction to Fiber Optics

– Optical Metrology & Interferometry

– Precision Positioning & Motion Control for Optical Systems

– Introduction to Vibration Control

• Bringing on the ground temporary lab equipment for specific courses to the UC Irvine

Extension Campus

• Adding on the ground lab facilities in cooperation with Irvine Valley College ATEP campus

and local optics businesses.

We also have an outline for a 1 week summer course at the UC Irvine Extension Campus that would

introduce potential students to these courses and the programs.

We are grateful to our students, our instructors, the UC Irvine Extension Staff and our Advisory

Committee who all continue to support these programs.
