Abstract

The study was conducted  to obtain the effect of using flash card during   learning with jigsaw cooperative model  on student` activity and their achievement. This study used  pretest-postest not equivalent designed on sample which was selected  using cluster random sampling sample technique. The data of student` concept mastery were obtained from  test (pretest and posttest), observation sheet (students learning activities) and student`s  respons questionnairet about this study. The student`s concept mastery was categorized according to Bloom Taxonomy namely  Data was analyzed using  t-test on the SPSS17 program.The  N-gain  score obtained showed that  the experimental class was better than  the control ones.  The study indicated that the flash card usage affecting student`s concept mastery espescially on comprehensiveness (C2) aspect, but not analysis skill (C4) aspect.  The average  student learning activity of experiment class was 75,12 %  which was high category. Based on the stud it can be concluded that the used of  flash card in Jigsaw  cooperative learning model  significantly enhanced  student`s  learning activities and their concept  mastery. Keywords: Flash card, Jigsaw, student learning activity, material mastery, matter material of Virus.

Abstract

Based on observation and interview with biology teacher in SMP N 4 Gedongtataan, students learning activities and concept mastery were not optimally developed yet. An alternative that can be used to improve learning activities and concept mastery is using laboratory equipment. This study aims to understand the influence of laboratory equipment utilization towards student activities and concept mastery. This study is quasi experiment using pretest posttest group non equivalent design. Sample in this experiment are students from VIII C and VIII D which obtained from population by cluster random sampling method. Quantitative data obtained from average of pretest and posttest scores which statistically analyzed with U-test using SPSS version 17 in 95% confidence levels. Qualitative data are student’s concept mastery, learning activities and students responses about laboratory equipment utilization which descriptively analyzed. Result of this study shown that the average of students concept mastery in experimental class are higher than control (experiment= 65.81; control = 29.1). The average of student learning activities percentage in all observed aspects in experimental class shown higher enhancement than control (experiment = 79.9; control = 72.21) most of the students also gives positive responses to laboratory equipment utilization.  Key words: structure and function of plants tissues, laboratory equipment media

Abstract

The observations and discussions with teachers who taught in Biology class III SD Negeri 1 Kampung Baru Lampung, it is known that the dominant learning more teachers using the conventional approach. Students also receive more information from the teacher so that students are less than optimal in empowering potential, including critical thinking skills. One effort that can help empower students in critical thinking skills is to use science process skills. The purpose of this study was to determine the effect of the use of science process skills for critical thinking skills of students in the subject matter of Characteristics and Needs of Living Things. The study design is a group pretest-posttest non-equivalent. The samples in this study were grade IIIA and IIIB were randomly selected by random sampling technique clusster. Data were obtained from the pretest and posttest at each meeting, the gain score is calculated by the formula. Data analysis using t-test at 5% level of belief using SPSS 17. The results of this study indicate that there is a significant effect of the use of science process skills for critical thinking skills of students in the subject matter of Characteristics and Needs of Living Things. Critical thinking skills students are learning in the classroom using science process skills approach higher grade than learning to use a conventional approach.

Abstract

One effort to improve the learning outcomes of natural science subjects, the researchers are interested in examining the effectiveness of cooperative learning. According to the theory of constructivism, learning is a construct knowledge based on prior knowledge. Thus, the ability to beginning students could be expected to affect the learning outcomes. Researchers applying two cooperative learning model type is the type Student Achievment Team Division (STAD) and Group Investigaton (GI) and the two classes. The technique used in this study is proces sampling techniques, and data collection and processing be conducted to obtain data on knowledge and attitudes. The instrument used was a test sheet and questionnaire. To analyze the data the normality test, homogeneity test, t test, and N-gain.Result of different of average from pretest and postest score get 60 percents for experiment class (STAD type) and 40 percents for control class (GI tipe). Result from average scores of questionnare get 70 percents for experiment class (STAD type) and 40 percent for control class (GI type). From the result of count above show that there is significant different and positive influence between knowledge result and student attitude which using coopertative learning model of STAD and cooperative learning model of GI.Keywords: Conservation, STAD learning model, GI, students' Knowledge, Attitudes of students, Mangrove Conservation

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. Keywords: Leaflets, Jigsaw, results of learning, human development.

Abstract

This study aims to find out  the improvement of students` problem solving skills on environmental pollution and conservation concepts of  X grade student of  SMA N 1 Talang Padang using Group Investigation learning model. The  study  used  pretest-posttest non equivalent design. Sample were X5 as experimental class and X3 as control  chosen from population using  randomized block  sampling technique. Data of students problem solving skill was obtained using  pretest and posttest, while data of  students` learning activities was observed and the data obtained was statistically analyzed using t-test with SPSS 17 program.The study  showed  that there was  improvement of students` problem solving skills  with  61.67 N-gain score. The GI learning model effected  students` problem solving significantly espescially on three aspects such as  identifying problem, formulating problem, and giving alternative solution.The GI learning model also  affected students` learning activities significantly on the students  expressing opinions / ideas  skill and discussions. The study concluded that the GI  learning models can improve students' problem solving skills and enhance student learning activities on environmental pollution and conservation concepts.Key words:     Group Investigation (GI) learning model, problem solving skills, learning activities, environmental pollution, environmental conservation.
