1 Strategies in Implementing Chemistry Writing Tasks

2 Teachers need to design The Chemistry topic; The specific genre for writing

3 Lesson Plan 1

4 (1) Brief Notes on Chemistry Specific Genres - Sentence patterns of writing topics - Structure - Language Features 10 mins

5 Sample Text (CE question) Language Features Structure

6 (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

7 (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 -- write with guidelines and support

8 (3) Guided Writing (B) Using Writing Framework 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.) 30 mins

9 Procedure How to You will need Diagram or drawing First Then Next After that Finally Procedural account

10

11 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 Comparison

13 (4) Writing Assignments Writing with topics in HKCEE or NSS Chemistry Curriculum (with / without guidance) 40 mins

14 Lesson Plan 2

15 (1) Brief Notes on Chemistry Specific Genres - Sentence patterns of writing topics - Structure - Language Features 10 mins

16 Sample Text (CE question) Language Features Structure

17 (2) Interactive Exercise on Chemistry Specific Genres 20 mins

18 (3) Writing Assignments Writing with topics in HKCEE or NSS Chemistry Curriculum (with / without guidance) 40 mins

19 (4) Summative Assessment Questions with effective communication in tests or examinations 40 mins

22 Modelling : A form of language support

23 (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.

24 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 in oxygen, a _______ solid is formed. The product is called _______________. lead yellow lead(II) oxide

25 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.

26 (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.

27 Example : Descriptive Report

28 Writing - Descriptive Report ( modelling with same genre)

29

30 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. Assessment rubrics :

31 HKEAA CE Questions with Effective Communication Organization structure, Presentation (A),(B),(C) marks

32 AL Paper I Section C Organization structure, Presentation (O),(L) marks

33 Emphasize the Use of Genres - Structure of genres - Select certain language features required in that genre - Marking scale with marks and feedback (C),(S),(L) marks Writing Assignment with specific genres
