D. Learning Material
Fourth Meeting: Refraction in the Lens
E. Learning Method
Fourth Meeting: Class Discussion
F. Learning Activities
Fourth Meeting (150 minutes)
- Preface Activities (10 minutes)
1.a. Teacher greets the students
1.b. Teacher leads the class to pray before the lesson
Teacher asks the students, “What is the kind of lens that suitable with the each phenomenon? Myopic and hypermetropic (hipermetropi) eyes can see a fix object in front of the eyes. What are the kind of especially lens we need for myopic and hypermetropic (hipermetropi) eyes?”
- (^) Students may hypothesize/respond the phenomena: Myopic eyes need concave lens, especially concave-convex lens and hypermetropic (hipermetropi) eyes need convex lens, especially convex-concave lens.
d. Teacher asks the students to form a group that contains for 4 persons.
e. Teacher gives worksheet to the groups.
f. Teacher reads the rule of discussion.
- Actively give opinions.
- Appreciate others opinions.
- Brave to give opinion and be an open-minded.
- Have no fear to be criticized.
- (^) Be active to give opinion from beginning to end of discussion.
Phase 3: Hold Discussion (40 minutes)
f.a. Teacher monitors the discussion process in each group.
- (^) Students gather to discuss the phenomenon given.
f.b. Teacher observes the students’ behavior while discussion.
- Students and each group would:
- Do experiment about the refraction in concave and convex lens.
- Collect and process the data established. (Collecting data)
- Analyze the data until obtain the result. (Associating/ Reasoning)
- Conclude the ‘whole’ result from the experiment.
f.c. After several times, teacher asks each group to conclude the result of their discussion.
- (^) Each group present their discussion result. (Communicating)
f.d. Teacher helps the student to make a conclusion from the group conclusion.
- Students make a ‘big’ conclusion.
Phase 4: End Discussion (25 minutes)
f.a. Teacher scaffold the students’ knowledge by giving question in order to clarify the concept from the conclusion they had made.
“What is the difference of concave and convex lens?”
f.b. Teacher clarifies the concept of convex and concave lens.
- Student try to explain the difference of concave and convex lens by using the teacher’s scaffolding question and from the knowledge they got in the last activity. (Communicating)
Phase 5: Debrief the Discussion (20 minutes)
a. Teacher gives a video about eyes see on the microscope and telescope.
- Students observe the video and give their opinion. (Communicating)
- Closure Activities (15 minutes)
1.c. Teacher asks the student to reflect the learning result that they are got today by giving question:
- How do light propagates in the convex and concave lens?
- What is the characteristic of shadow in concave and convex lens? 1.d. Teacher provides a self-assessment of spiritual and social attitude for each student. 1.e. Teacher greets students.
- Student Worksheet : Attachment 2.2.
- Teacher Worksheet : Attachment 2.2.
