Abstract

Problem-solving skill is a thinking skill that must be developed in junior high school. Classroom observations from VII grade Junior High School 2 Waylima shows that problem-solving skill is still low. This study aimed to determine the effect of PBL models in improving problem solving skill. This study design is non equivalent pretest posttest group. Samples was VIIID and VIIIE grades selected by purposive sampling. This research data in the form of quantitative and qualitative data. Quantitative data obtained from the average value of pretest, posttest and N-gain was analyzed using t-test and U test. Qualitative data in the form of descriptions of student learning activities, and questionnaire responses. The results showed that PBL model can improve problem-solving skill by students with average score of pretest (50.64); posttest (75.32), and N-gain (0,50). Learning activity also increase with an average of 86.45%. In addition, most students responded positively with used of PBL models. Thus, it can be concluded that the used of PBL model significantly affect problem-solving skill in the influence of human population density toward evironment subject matter.

Abstract

This research aimed to know the effectiveness of laboratory based learning on student science process skills (KPS) and  scientific attitudes. The design was pretest-posttes non equivalent group by purposive sampling so those class VII H and VII I were choosen as subject. The quantitative data  was KPS that analyzed by t test and U test. The average value of pretest and posttest with pretest average of 39,09; posttest average of 73,85; and an average gain of 0,16. The average increase in all KPS aspects that were observed had moderate criteria (34,52). The qualitative data were obtained from observation and questionnaire, analyzed descriptively. Observation result of KPS had high criteria (81,67), the observation of a scientific attitude had a very high criteria (89,77) and from students questionnaire data showed nearly all students have a scientific attitude. Thus, it can be concluded that laboratory based learning is effective in improving students KPS and scientific attitude.Penelitian ini bertujuan untuk mengetahui efektifitas pembelajaran berbasis praktikum terhadap keterampilan proses sains (KPS) dan sikap ilmiah siswa.

Abstract

The observations were performed in the Junior High School  2 Ambarawa , especially the eighth grade, biology shows that subjects regarded as a difficult subject understandable to students. This is because learning takes place in conventional and low interest in reading students' biology textbooks. One effort that can be done to increase reading and student results of learning is through the use of  Leaflet teaching materials types Jigsaw Cooperative Learning Model. This study aims to determine the improvement of student results of learning in the subject matter of human development after being treated with a Leaflet through tipeJigsaw koopertif learning model. The results showed an increase in the average between pretest and posttest values were measured with N-gain in the experimental class at 55.75 is higher than the control class at 46.89. Average of the highest values in the aspect of understanding that is equal to 59.75 while the average low of results of learning in analyzing aspects of 34.2. Average student learning activities in the experimental class higher at 75.53 compared to 68.34 in the control classes. Given these results it can be concluded that the use of instructional materials Leaflets through Jigsaw cooperative learning model type significantly in improving students' junior high school 2 Ambarawa on the subject matter of Human Development.

Abstract

Two elements that very important in the learning process are model and media instructional. The observation was known that teachers not give an opportunity for students to develop independently so that students' critical thinking skills are underdeveloped. This study aimed to determine the effect of the use of audiovisual media through PBL models in improving critical thinking skills by students. The research design was pretest posttest equivalent group. The research sample class X2 and X5 are selected by cluster random sampling. The results showed that the use of audiovisual media through PBL models can improve critical thinking skills by students with average pretest (20.45), posttest (73.13), and N-gain (0,66). The average percentage of students also increased activity in all aspects of that observed with good criterion (85.04). In addition, the majority of students (89.68%) gave positive response about the use of audiovisual media through PBL models. Thus, we can conclude the use of audiovisual media through PBL models have a significant effect in improving critical thinking skills by students in the subject matter of environmental pollution and preservation efforts. Keywords: PBL models, audiovisual media, critical thinking skills, environmental pollution and preservation efforts.
