IMPLEMENTATION OF PROBLEM SOLVING LEARNING MODEL WITH OPEN-ENDED TYPE WORKSHEET ON SUB MATTER ENTHALPY CHANGES TO COMPLETING STUDENT LEARNING OUTCOMES

Abstract

The implementation of this research is remedial teaching aimed to completing student learning outcomes , also to describe the learning implementibility, student activities, and student response to the implementation of problem solving learning model with worksheet open-ended problem solving. The method used in this research were observation, tests and questionnaires. The results showed that the learning process through the Implementation of problem solving learning model with worksheet open-ended problem solving, obtain the percentage of learning at the meeting I, II, and III respectively 87.2%, 91.9%, and 88.7% on very good category. Students activity at the meeting I, II, and III get a percentage respectively 82.1%; 88.9%; 93.2% on very high category. Student learning outcomes with the Implementation of problem solving learning model with worksheet open-ended problem solving has been completed that is 77.8% completed individually and student learning outcomes by 81.5% of students (22 students) get gain score with high category and 18.5% of students (5 students) get gain score with moderate category. In addition, the student response after learning process obtained percentage of 97,7% on positive category.

Key Words: student learning outcomes, open ended problem solving, enthalpy changes
