Abstract

This study aims to look at the effect of the Physics Problem Solving Exercise by using the "Minnesota Strategy" Problem Solving Model to improve Student Learning Outcomes and Critical Thinking Abilities in SMA 3 Seunagan. The approach used is a quantitative approach in the form of experimental research. Then the data is analyzed using N-gain and t-test. Hypothesis testing used by one-party test that is the right hand side, with criteria accepted by H1 if tcount ttable and H1 is rejected if tcount ≤ ttable. Hypothesis test results obtained for student learning outcomes data tcount = 4.18 and ttable = 1.68 and for critical thinking data tcount = 5.09 and ttable = 1.68 then it can be concluded tcount ttable, in other words H1 accepted. The conclusion of this research is that there is an influence on the use of Physics Problem Solving Exercises by using the "Minnesota Strategy" Problem Solving Model to improve Student Learning Outcomes and Critical Thinking Ability.Keywords: Minnesota Strategy, Learning Outcomes, critical thinking skills.

Abstract

Students’ critical thinking skill of class X MIA-1 in SMAN 2 Bukit is very low. There is the effort to improve critical thinking of students applying Project Based Learning model (PjBL). The purpose of this research is to determine whether there is an enhancement in students’ critical thinking skills using the Project Based Learning model. This research is Classroom Action Research which was carried out as many as III cycles. The subjects in this research were all students of Class X MIA-1 in SMAN 2 Bukit, consisted of 16 students. The instrument used to collect the data was tests including pre-test, post-test, teacher and student activity sheets, and observation sheets of learning management using Project Based Learning model. The results showed that students’ critical thinking skill when Project Based Learning model applied was better than the learning which was not using The Project Based Learning model. It happened because using Project Based Learning model, the students played a role actively as learning center were given an issue in the project then they were asked to solve it.
