PENERAPAN MODEL PEMBELAJARAN LOGAN AVENUE PROBLEM SOLVING-HEURISTIK DALAM MENINGKATKAN HASIL BELAJAR PESERTA DIDIK PADA MATERI TITRASI ASAM BASA
Hopefully at the end of this learning is to improve the quality of students. One of the result of escalation can be achieved by following the learning model of Logan Avenue Problem Solving-Heuristic. This research was proposed to know the learning outcomes to the students grade XI IPA after applied logan avenue problem solving-heuristic learning model in acid base titration. The research conducted on April 2019 in Senior High School 2 in Tanjungpinang. The type of this research was quasi experiment with one group pretest-posttest design. The data of the research were based on the learning enhanchment of the students such as pretest and posttest in multiple choice exam in acid base titration lesson. The population in this research came from all the students in grade XI IPA, with the amounth of samples about 35 students especially in grade XI IPA 1 by using cluster random sampling method. The result of the research obtained pretest score was 66 and posttest score was 81. Based on the learning outcomes data, the N gain test showed score of 0.43 with precentage was 43% which it was indicated that the learning model of LAPS-Heuristic was “not too effective” to improve of student learning outcomes in grade XI IPA at SMA Negeri 2 Tanjungpinang on acid base titration lesson.
