F. Learning Approach and Model
1. Approach:
Contextual
2. Model: Guided
inquiry learning
G. Steps of learning activities
a. Introduction (15 minutes)
Phase 1 : Presenting Activities
1. Teacher enters the class and greets the
students with “Assalamualaikum Students!”
2. Teacher creates a religious classroom
atmosphere by appointing in the class leader to lead the prayer
3. Teacher checks student attendance(teacher
still discipline attitude),cleanliness and class neatness as a form of
environmental awareness
4. After preparing the lesson,the teacher
conveys a preception to the students with the aim of guilding the students
memory on the materials to be given at this meeting by asking “what is solution
and solute?”
5. Students are asked to answer the question
and the teacher completes the student’s answer
6. Teacher motivate students to attract
students attention with describe the process of cooking water in daily life
then ask, “when is the water boiling?”
7. Students are asked to answer and then
completed by the teacher
8. Teacher divide students into group with
heterogeneous members
b. Core Activity (60 minutes)
1. Teacher distributes LKS to each group and
presents the problem: “at what temperature in the following solution boiling
and which in the first boiling?”
a. 10 mL of aquades
b. 10 mL of 0,5 M NaCl solution
c. 10 mL of 1 M NaCl solution
Phase 2 Creating Hypotheses
2. Teacher provide opportunities for students
to discuss each other to make hypothesis and write it to LKS.
Phase 3 Designing Experiments
3. Teacher give students the opportunity to
develop experimental steps in the group discussion within a few minutes guide
students to develop the correct procedure right on the board.
Phase 4 Experiment
4. Teacher guide students to experiment to
test hypothesis that have been students were made with experiments of boiling
point in some olutions that has been provided.
5. Student make observations and record
carefully and then throughly the results of their experimental oservations on
the LKS.
Phase 5 : Collecting and Analyzing Data
6. Students analyze experiment data, make a
discussion of the results that they get by comparing the existing literature to
prove thecorrectness of the hypothesis they make,and answer the questions in
the LKS.
7. the teacher gives each group a chance by
pointing to one members of his group todeliver the results of data processing
collected at the front of the class and other groups give attention and respond
for his friend’s presentation, then the teacher gives the reinforcement for the
results of student’s discussion to make students can understand the concept of
boiling point rise and calculation correctly.
8. The teacher gives students the opportunity
to ask questions if the students not understood anymore about the lesson.
c. Closing (15 minutes)
Phase 6 : Make a conclusion
9. Teacher asks student to collect LKS
10. The teacher guides the students to
conclude the materials of lesson that they habve learned
11. Teacher asks th question is “do you feel
happy and understand the lesson today?”
12. Teacher closes the lesson by giving the
tasks of a report to each group and written test in the form of homework (PR) n
each student.
