In order to survive and improve self quality in higher levels of education and work, generic science skills are needed. Generic science skill is the skill that can be grown from science learning as a provision to pursue careers in a broader field. In this day and age, many things can be done by using devices, including physics learning. This study aims to find out the differences of generic science skills improvement between a class that apply solar system learning with a scientific approach assisted by Solar System Scope with a class that do not use Solar System Scope. The method used in this study was quasi-experiment with the control group pretest-posttest design. The sample consisted of 31 experimental class students and 31 control class students in the junior high school in Bandung. Both classes were given the multiple choice test. The results of data analysis showed an improvement in both classes with N-gain 45.9% in the experimental class and 22.8% in the control class. The conclusion of this study can be showed by Mann Whitney hypothesis test which produces z = -3.60. It shows that there is a significant differences of generic science skills improvement between both classes after the implementation of solar system learning assisted by Solar System Scope.

This is a quasi experiment with pretest-postest control group design. The population of this research is all students of class X IPA SMAN 4 Mataram. The sampling technique used is purposive sampling. There are two samples taken that is sample as a class given treatment in the form of learning using scaffolding expository aided learning model (class X IPA 1) and classes treated using expository learning model assisted advance organizer (class X IPA 2). The data of learning outcome is obtained by using the multiple-choice test of 25 questions. After hypothesis testing using statistical test (t-test separated varian). The first hypothesis testing showed that tcount > ttable which means that Ho1 is rejected and Ha1 is accepted. The second hypothesis testing showed that, tcount > ttable which means that Ho2 is rejected and Ha2 is accepted. Based on the hypothesis test, it can be concluded that there is effect of expository learning model with scaffolding and advance organizer to the physics learning outcome of students.

Scientific Learning

Based on observations and interviews with a science teacher at a junior high school in Pesisir Selatan Regency, it is known that there are still many science teachers who have not carried out practicum activities in scientific learning. Science kits are rarely used by teachers in science learning. The main reason is that the competence of science teachers in operating the science kit is still low. To improve the competence of science teachers in using KIT, it is very necessary to carry out activities to optimize the use of KIT for science teachers. The purpose of this study was to improve the competence of science teachers in using IPA KIT as a support for scientific learning. This type of research is a quasi-experimental design with a pretest-posttest using multiple choice test instruments at the beginning and at the end of the study. From the results of this study, it is known that there is an increase in the competence of science teachers in using science kits, with the percentage increase of 29.25%.

The science learning outcomes of grade VIII students at MTsN Lawang Mandahiling are still low. Students physics's low learning outcomes are because teachers still dominate physics learning, and the intensity of student involvement when learning is a little. This study aims to determine how to apply a scientific approach to the Inside-Outside Circle cooperative learning model for students' physics learning outcomes. This type of research is quasi-experimental research, with the research design used is posttest only control group design. Sampling used random sampling, resulting in two sample classes, namely class VIII.2 as the experimental and VIII.3 as the control class. The data collection used a test of student learning outcomes on knowledge competencies in a multiple-choice test of 20 items. The competency data of students' attitudes and skills used observation sheets which were analyzed qualitatively descriptive. The results of the final tests conducted in the study showed that the physics learning outcomes of students in the experimental class were better than the control class. The average final score of students for knowledge competence in the experimental class and control class, respectively, was 78.00 and 66.00. For attitudinal competence, the average scores obtained by the experimental class and control class were 68.98 and 65.34, respectively. For the competency skills, the average scores obtained by the experimental class and control class are 74.22 and 68.25, respectively. Hypothesis testing is done by using a t-test. From the calculation on knowledge competency, the result of tcount = 3.07 while ttable = 1.684; on attitude competence, the price of tcount = 2.29; on skills competency, the tcount = 4.26; while ttable = 1.684 while t table = 1.684 at the real level α = 0.05. It means that tcount> ttable so that H0 is rejected and H1 is accepted. It can be concluded that the students' physics learning outcomes in applying the synthetic approach to the Inside-Outside Circle cooperative learning model are better than the physics learning outcomes of students who do not use the Inside-Outside Circle cooperative learning model in solar system subject matter in grade VIII  MTsN Lawang Mandahiling.

This study was aimed at finding out The Effect of Applying POSSE (Predict-Organize-Search-Summarize-Evaluate) Strategy on the Students’ Reading Comprehension. This study used the experimental design. The population of this study was the students of SMA Negeri 2 Medan. There were sixty students taken as the sample of the research. This study was conducted with two randomized groups namely experimental and control group. The experimental group was taught by applying POSSE strategy while control group was taught without applying POSSE strategy. The instrument of collecting the data was multiple choice test which consists of 40 items. To obtain the reliability of the test, the researcher used Kuder-Richardson (KR-21). The calculation shows the reliability was 0.81(high). The data were analyzed by using t-test. The calculation shows that t-observed (4.76) is higher than t-table (2.00) at the level of significance (α) 0.05 with the degree of freedom (df) 58. Therefore, the null hypothesis (Ho) is rejected and alternative hypothesis (Ha) is accepted. It means that there was a significant effect of applying POSSE strategy on the students’ reading comprehension. Keywords: POSSE Strategy, Reading Comprehension.

This study aims to determine the effect of Science Learning Model, Environment, Technology, Society assisted Environmental media on Science Competence of grade V students. The type of this research was quasi experiment with non-equivalent group design. The population in this study was the entire class V in the Srikandi cluster East Denpasar amounted to 362 students. The sample of this research was class V of SDN 5 Sumerta were 28 students as experimental group and class V of SDN 10 Sumerta were 28 students as control group. Data collected with multiple choice test instruments, then was analyzed using descriptive statistical analysis and inferential statistical analysis (t-test). Based on the data analysis, tcount = 2.500 and ttabel (5% significance level) = 2,000. This means that tcount = 2,500> ttabel = 2,000. There was a significant difference of science competence between groups of students who was taught by science learning model, Environment, Technology, Society assisted Environmental media and group of students which is learn through conventional learning. The average value of science competence of the experimental group ( ) is 79.00 while the mean score of control group students ( ) is 74.07. This means =79,00 > =74,07, so it can be concluded that the application of learning model of Science, Environment, Technology, Society assisted Environmental media influenced the competence of science. Based on the results of this study it is suggested that the results of this study can be used as a relevant study, especially as supporting the next research.
