Abstract

The research was conducted to improve the Critical Thinking Capability in detail: 1) Describe the thematic-integrative worksheet on integrated IPA Subjects, 2) Measure the critical thinking skills of students as the effect of the thematic-integrative Worksheet material, and 3) Describe the student's response to the teaching material Worksheet thematic-integrative. The resulting product development is an thematic-integrative Worksheet to support a learning process that can improve critical thinking skills. The thematic-integrative worksheets developed have met the criteria of validity and according to the expert. The test results have shown that the thematic-integrative Worksheet teaching materials are more effective. All learning tools used are in valid categories and are eligible for use. The results of the first trial showed that students' critical thinking skills were averaged 76.7 (critical categories), while the second test reached an average of 84.4 (very critical). Based on the analysis result, it is found that the thematic-integrative worksheet developed can develop critical thinking skill.

Abstract

Based on the observations and interviews of some physics teachers, it was found that the teacher felt that he had tried to improve the learning techniques in the classroom. But the activity and achievement of student learning not yet according to expected result. The learning pattern applied is teacher-center learning. Therefore, this is very inconsistent with the characteristics of science learning. PhET (Physics Education Technology) application program is one of the learning tools that requires students to take an active role during the learning process. This study is a classroom action research conducted in two cycles to determine the effectiveness of learning. Each cycle takes place in two sessions. Each cycle consists of the stages of planning, implementation of action, observation, evaluation, and reflection. The subject of the research is the students of class IX.1 SMPN 2 Lingsar. The results of the evaluation of cycles I and II showed a significant increase. The average score of student learning activity increased from 7.95 to 11.39 (medium to high category) and the average student evaluation score increased from 62.5 to 76.65. We concluded that the PhET application program is effective for increasing activity and student learning outcomes.

Abstract

This study was aimed to analyzethe effect of project based learning model to understanding concepts  and critical thinking skills in optics lecture at undergraduate student of Physics Educational Program of IKIP Mataram in academic year 2013/2014. This study included in quasi experiment with posttest onlycontrol group design. All of 75 populations are included as sample. The datawere analyzed with multivariate analysis (MANOVA).The conclusion can be stated based on analysis result is (1) project based learning model having an effect on understandingconcepts of undergraduate students ((Fcal = 37,88 > Ftable = 3,91), with pvalue<0,05. (2) project based learning model having an effect on critical thinking skill of undergraduate students ((Fcal = 5,47 > Ftable = 3,91), with pvalue<0,05. (3) project based learning model having an effect on both understandingconcepts and critical thinking of undergraduate students ((Fcal = 34,86 > Ftable = 3,91), with pvalue<0,05.

Abstract

This study aims to determine differences in physics student learning achievement which using the worksheet oriented thinking abilityinductive with deductive. This research is experimental research (quasy experimental design). The study population was all students of class X in SMKN 3 Mataram with the study sample consisted of two classes, X GEO B and X TSM B. X GEO B class taught using worksheet  oriented thinking ability inductive and X TSM B class taught using worksheet oriented thinking ability deductive. Instruments in this study using multiple-choice test. The results of post-test data analysis obtained the average value of the two classes of samples is 81.27 (X GEO B) and 72.25 (X TSM B) so obtained tcount = 3.56, while ttable = 2.00 at significance level of 5% so that the alternative hypothesis (Ha) accepted. These results show that there are differences in physics learning outcomes of students who use the worksheet oriented thinking ability inductive with deductive.

Abstract

This study is a quasi experimental study that aims to determine the effect of using direct instruction model with animation media to the academic achievement of physiscs in student class VIII SMP Negeri 1 Batu Layar. The population in this study were all students of class VIII SMP Negeri 1 Batu Layar that were 87 students. Whereas the students of class VIIIA which are 22 students as the experimental group and 22 students of class VIIIC as a control group. Sampling methode was random cluster sampling. The Research design using pre-test - post-test control group design. Based on Pre-test result, the average mark of class VIIIA and class VIIIC were 24.70 and 28.95, respectively. Post-test result gave the information that the average mark of class VIIIA and class VIIIC were 79.29 and 71.62 respectively. Research hypotesis was analyzed using polled varians t-test. It can be concluded that there was a different in physics academic achievement between experimental group and control group, where the experimental group using direct  instruction model with animation media as the treatment and the control group using direct instruction only. The academic achievement of experimental group were better than control group, it can be a reason to say that the treatment by using direct instruction model with animation media gave the positive effect to the academic achievement of physiscs in student class VIII SMP Negeri 1 Batu Layar.
