Strategies

Active Reading and Writing Tasks

Objectives of the Workshops

1. To promote the use of active reading and writing tasks in the learning and teaching of chemistry

2. To share experiences in conducting reading and writing tasks in the chemistry lessons

3. To discuss on how to develop activities from different resource materials

4. To discuss on how to assess students' reading and writing tasks

1. Why promoting reading and writing in chemistry?

IMPORTANT?

Reading and Writing #1 Suggested Learning and Teaching Activities in

NSS:Topic II: Reading articles or writing essays on the

applications of materials such as graphite and aluminium in relation to their structures.

Topic V: Searching for information or reading articles about the discovery of polyethene and the development of addition polymers.

Topic VI: Reading articles on how Valence Shell Electron Pair Repulsion (VSEPR) theory can be used to predict the shapes of molecules.

Reading and Writing #2 Where in the curriculum? Topic VII:

Introduction: “Through searching for information and critically reading materials about electrochemical technology, students should appreciate the contribution of chemical knowledge to technological innovations, which in turn improve our quality of life”

Reading articles about the industrial processes involved in the production of aluminium from aluminium ore.

Reading articles about new developments in fuel cell technology and lithium cells.

Students do not like reading?

Students’ problems?Lack of interestLack of skills

Textbooks’ problems?Not fun / Not attractiveHard to readLots of digressionsLots of irrelevant information

Some opinions

Reading for information and enjoyment

Promotion of science learning alongside the

development of language ability

Copying notes from the board or from

worksheets does little to encourage language

skills (OFSTED, 1995, par. 26)

Dominance of “doing” over “reading and

thinking”? (Turner & Dimarco)

Nature of ScienceMore than practical skillsMore than information processing skillsChemists do need reading and writing

skills

Some Learning Targets of NSS Chemistry CurriculaPractical skillsInformation handling skillsCommunication skills: oral, reading

and writingDo we have good support from language

subjects?Can students transfer their skills learnt in

language subjects to chemistry?

Themes for Reading

Curriculum bound?Curriculum linked?

For enhancing scientific literacy – values and attitudes, STSE connection

For enhancing interest in chemistry

Helping students to read

How to distinguish trivial details from important

generalizations?interesting information from

important information?How to facilitate students have not

master the reading skills to read?

Student 1:

I read through a section quickly. I try to figure out why it was put there and then I’ll go back and underline as few words as possible.

Student 2:

I underlined with the highlighters. I used two colors. I wanted to give one color more importance than the other. It would mean more to me later.

Reading and writing tasks as NSS Chemistry SBA

tasks?

Examples of SBA Tasks1. critical reading, analysis and reporting on the

contribution of chemistry to the understanding of the material world

2. designing a poster or pamphlet aimed at persuading people to follow the principles of green chemistry

3. writing a report to present the scientific knowledge and concepts acquired after a visit to an industrial plant, and

4. developing a multimedia artefact to illustrate the synthesis of polymers.
