Abstract

The research objective was to determine the effectiveness student worksheet based guided inquiry for growing students critical thinking ability. The research method is quasi experimental with one group pretest posttest design. Random sample selection from population class VIII SMPN 22 Bandar Lampung year lesson 2016-2017, so that obtained class VIII E and VIII G as sample. Quantitative data in the form of pretest, posttest, and n-Gain result were analyzed inference using t-tes. Qualitative data in the form of observation result of teacher ability anf student activity in learning analyzed descriptively. The result showed n-Gain critical thinking ability of experiment class students (0.35) higher than control class (0.25). The ability of teachers and student activities in learning is very high. Thus it is concluded that the use of Student worksheet based guided inquiry effectively fosters students critical thingking ability.Penelitian ini bertujuan mengetahui keefektivan penggunaan LKS berbasis inkuiri terbimbing dalam menumbuhkan kemampuan berpikir kritis siswa.

Abstract

The aim of this research is to know effectiveness of problem solving learning model in enhancing inferring and communicating skill in colloid material. Populations were all 227 students of Grade XI science in YP Unila Senior High School in Bandar Lampung. The samples were 36 students in classroom XI science one and 39 students in classroom XI science two that have equal academic abilities. This was a quasi experiment research using non equivalent control group design. Effectiveness of learning with problem solving model was measured based on significant gain enhancement. The result showed that average values of N-gain of inferring skill in experiment and control classrooms were 0.59 and 0.47 respectively; and average values of N-gain for communicating skill in experiment and control classrooms were 0.56 and 0.47 respectively. The hypothesis result test showed that classroom that used problem solving learning model had higher skill in inferring and communicating than classroom with conventional learning model. This indicated that problem solvinglearning model was effective to enhance student’s inferring and communicating skill in colloid material.Keywords: Problem Solving, inferring and communicating skill
