Transcript Workshop 5 Session 3
Strategies
in Implementing Chemistry Writing Tasks
Teachers need to design •
The Chemistry topic;
•
The specific genre for writing
Lesson Plan 1
(1) Brief Notes on Chemistry Specific Genres
- Sentence patterns of writing topics - Structure - Language Features
10 mins
Structure
Sample Text (CE question)
Language Features
(2) Question Analysis •
Read the question carefully
Sentence patterns of writing topics
•
Determine the relevant chemical content
•
Determine the genre of the essay to be written
20 mins
(3) Guided Writing
-- write with guidelines and support (A)Using Graphic Organizers
Reading:
Text-to-Graphic activities
Writing:
Graphic -to-Text activities
Advantages
: • Illustrate the key content words explicitly • Help students understand how the ideas are related to each other • Help students understand the genres of the writings
(3) Guided Writing
(B) Using Writing Framework
30 mins • The
basic structure
of the genre can be provided as guideline.
•The flow of ideas can be guided by listing related
connectives
in sequence and
special language patterns. (
A form of language support.)
How to You will need Procedure Diagram or drawing First Then Next After that Finally
Comparison frame
________________ and ____________________ are alike in some ways as follows.
For example they both They are also similar in The _________________ resembles Finally they both ________________ and ____________________ are different in many ways.
The __________________ has _________________ whilst / whereas ____________________ has ___________________.
They are also different in that Another way in which they differ is Finally

Modelling :
(a) Model Sentences
( for junior forms) • Provide students with model sentences and explore with the special features .
• help students understand how to structure different types of sentences better.
Write sentences to describe the chemical reactions occurred. Use the sentence patterns given in the example. (F3 Chem)
Example: burn magnesium + oxygen magnesium oxide ( white solid )
When
magnesium
is burnt
in oxygen, a white solid
is formed
. The product
is called
magnesium oxide . burn 1. lead + oxygen lead(II) oxide ( yellow solid )
When is burnt
The product
is called
in oxygen , a _______ solid
is formed
.
burn 2. Carbon + oxygen carbon dioxide (colourless gas )
When
carbon
is burnt
in oxygen, a colourless gas
is formed
. The product
is called
carbon dioxide.
(b) Model Texts
( for senior forms) • Provide students with a model reading text with a certain type of genre, then ask them to write a text with the same type of genre .
• Help students understand how to structure different types of genre better .
• Students can learn to express the concepts more explicitly and accurately .
Example :
Assessment rubrics :
• an authentic assessment tool used to evaluate a student's performance • a working guide for students and teachers, usually handed out
before
the assignment begins in order to get students to think about the criteria on which their work will be judged.
HKEAA CE Questions with Effective Communication (A),(B),(C) marks
AL Paper I Section C (O),(L) marks
Writing Assignment with specific genres (C),(S),(L) marks Emphasize the Use of Genres
-
Structure of genres
-
Select certain language features required in that genre
-
Marking scale with marks and feedback
