VI. LEARNINGMODEL :
Learning model : Cooperative
Type : Think Pair Share (TPS)
Learning method : Discussion, presentation and question and answer
VII. TOPIC : Stoichiometry (Buffer solution and Hydrolysis)
SUBTOPIC : The graph of acid base titration
VIII. LEARNING ACTIVITY
A. Introduction
Phase 1 : Present Goals and Set
Exploration
1. Teacher relate the topic that will be studied with the students’prior knowledge about
buffer solution and hydrolysis (stoichiometry)
2. Teacher motivate the student by asking to students “What is the mix solution that can
make the pH decrease or increase?”
3. Teacher explain the learning objective by using power point media.
B. Main Activity
Phase 2 : Present Information
Elaboration
4. Teacher distribute worksheet to each student.
5. Teacher explain outline of the matter by using power point media
6. Teacher inform to student about the learning model that will be used.
Think
7. Teacher ask the student doing worksheet that have been distribute independently
accurately.
8. Teacher walk around and observe student activities
Phase 3 : Organize Student Into Learning Team
Pair
9. Teacher divide the students into groups. Each group consist of two students (in
pairs).
Phase 4 : Assist teamwork and study
10. Teacher ask the student to discuss with member of each group about answer of
worksheet.
11. Teacher walk around and observe the activities of students in the group by
emphasize to student that open minded and listen friend’s opinion, and help friend
that needed are required in the discussion process.
12. Teacher guide the students in the group who have difficulty.
Phase 5 : Test over materials
Share
13. Teacher ask the students to present the result of their discussion in front of the class
with their group and the other students to be good listener.
14. Teacher ask the student to respond the discussion result of group presentation (giving opinion).
15. Teacher respond the ideas during the discussion.
16. Teacher give opportunity to student to ask the material that has not been understood.
C. Closure
Phase 6 : Provide Recognition
Confirmation
17. Teacher give feedback to the learning material
18. Teacher guide students to make summary or conclusion of this matter
19. Teacher give reward for the best group
20. Teacher end the learning process.
IX. LEARNING SOURCE
1. Student handbook
2. Worksheet
3. Computer and LCD
4. Power point media
X. ASSESMENT
