PENGARUH METODE PEMECAHAN MASALAH BERBANTUAN BUKU SAKU TERHADAP HASIL BELAJAR PADA MATERI POKOK STOIKIOMETRI DI KELAS X SMA NEGERI 1 SUNGAI RAYA

Abstract

ABSTRACTThis research had the purpose to find out the difference between students’ learning outcomes which were taught using problem solving method assisted pocket book and lectures method assisted pocket book as well as to know how large the effect of problem solving method assisted pocket book on students’ learning outcomes in class X of SMA Negeri 1 Sungai Raya on stoichiometry material. This research was Quasi Experimental Nonequivalent Control Group design. The sampling system was purposive sampling technique which considered the score of final exam. Based on the sampling technique, X C was choosen as control class and XA was choosen as experimental class. The techniques of data collection used measurement, direct communication, and direct observation techniques. The result of data analysis showed the mean score of pretestposttest in experimental class (73.1) was higher compared to control class (43.6). According to the statistical analysis of U-Mann witney test on pretest score (α= 0,05), it was obtained the P value which was 0.766 which meant that there was no difference between the ability of learning outcomes in experimental and control class. The calculation using effect size showed ES=1.88 which meant problem solving method assisted pocket book affected students’ learning outcomes which was 46.99 %. Problem solving method had high effect on students’ learning outcomes because the students were motivated to find the information or solution to solve the problem.Keywords : Pocket Book, Learning Outcome, Problem Solving Method, Stoichiometry
