The study aimed at improving students’ algebraic thinking ability in the eighth-grade junior high school student through multiple representation strategies using realistic approach. The multiple representation strategies consist of orientation, exploration, internalization, and evaluation. This is a quasi-experimental study with nonrandomized pretest-posttest control group design. The population of this study was the student the eighth grade in Kudus city. Two classes were selected and classified as a class experiment that subject are given multiple representation strategies using realistic approach, and one other class as a control class that subjects are given scientific approach. Data obtained was analyzed by the independent t-test and proportions test. The result showed that there was an interaction between the multiple representation strategies using the realistic approach on the ability of algebraic thinking. The students with multiple representation strategies had better algebraic thinking ability than those with current scientific learning. In addition, more than seventy-five percent of the students with multiple representation strategies using realistic approach fulfill the learning completeness.

This study was purposed to investigate whether or not there was a significant effect of storytelling using puppet strategy on students’ speaking achievement at eighth grade of junior high school at SMP N 1 Seririt in the academic year 2018/2019. The research design was Quasi Experimental of Posttest Only Control Group Design involving eighth grade students of SMP Negeri 1 Seririt. Cluster Random Sampling was assigned to select the sample of this study in which VIIIA Class was assigned as the control group and treated by using storytelling without puppet while VIIIB Class as the experimental group was treated by using storytelling with puppet strategy. Three kinds of instruments were used in this study namely lesson plan, speaking test, and storytelling rubric. Based on the result of the data analysis proves that there is a significant difference on students’ speaking achievement between students who were taught by using storytelling with puppet strategy and those students who were taught by using storytelling without puppet strategy (t= 4.942, df= 62, .p< 0.05). Moreover, the result of the effect size in this study is 0.282. It indicates that storytelling with puppet strategy give a large influence on students’ speaking achievement. Referring to those results, it can be concluded that storytelling using puppet strategy can give significant effect on students’ speaking achievement. Keyword: Puppet Media, Speaking Achievement, Storytelling

The misconception of the Solar System topic is still found in students so that it becomes one of the obstacles in the learning process. The purpose of this study is to analyze the effectiveness of the implementation of Predict-Observe-Explain-Apply (POEA) learning to change the junior high school students' conception in the Solar System topic. Quasi-experimental research with the non-equivalent control group design was conducted in one of the private junior high schools in Bandung city. Samples were selected based on the test of the average significance of the pretest score of the population. Furthermore, 30 students of the experimental class and 32 students of control class were selected. The research instrument, which consisted of 15 four-tier diagnostic test questions about Solar System were used to collect data before and after treatment. The tests were analyzed quantitatively by using the Mann-Whitney statistical test to determine the significance of the difference in the acceptable conception changes (Acceptable Change) of students in the experimental class with changes in the conception of students in the control class. The results of the research show that the implementation of POEA learning is significantly more effective than POE learning in changing the conception of Solar System topic. The findings of this study can be an alternative for junior high school teachers in planning learning about the Solar System, especially in an effort to change students' misconception about the Solar System.

This research aimed to understand the critical thinking ability improvement and preparedness assisted by Android-based media to understand landslides through physics learning and understand the effectiveness of the media. This research provides knowledge about disaster preparedness through physics learning in landslide-prone schools using Android media. This research used quasi-experimental with Control Group Design. The research subjects included tenth-grade students in class X (30 people) at SMA N 1 Kokap. The samples were selected using the lottery method and saturated sampling technique to determine the control and experiment groups (quasi-experimental with Control Group Design). The pretest and posttest were in the form of essay questions. The analysis data used independent sample T-test and effect size. The results show that the average critical thinking ability of the experimental class increased from 18.13 to 65.00, and the average preparedness increased from 68.75 to 81.88. The results of the independent sample t-test show the value of Sig. (2-tailed) on critical thinking ability was 0.000 and preparedness was 0.027 (Sig. (2-tailed) 0.05). Thus, it can be concluded that there are significant differences in critical thinking ability and disaster preparedness in the experimental class and the control class. The effect size of using an Android-based understanding of landslide natural disasters on students' critical thinking ability and preparedness is 2.0 with high effectiveness. Media landslides and landslides through Android-based physics learning can improve students’ critical thinking ability and disaster preparedness.

This study aims to examine the effect of mind mapping learning methods on social studies materials comprehension of students at Baleendah 2nd Junior High School. This study used a quasi-experimental method with the design of "nonequivalent control group design" with the pattern of "pretest" and "posttest" and carried out treatments in class VIII-F as the experimental class group and VIII-H as the control group used as a comparison. Sampling uses a purposive sampling technique. Data collection on the social studies material comprehension of students use questions as the main data. After the data is collected, the analysis is carried out quantitatively through hypothesis testing or T-Test. The results of the difference between "pretest" and "posttest" in the experimental class given treatment showed a significant difference in improvement, while the control class between "pretest" and "posttest" which were not given treatment the results were no difference or no improvement. It can be said that there are influences from mind mapping learning methods to on social studies materials comprehension of students.Keywords: comprehension of material, Mind Mapping Learning Method, Social Studies Learning
