AbstrakPenelitian ini bertujuan untuk mengetahui ada atau tidaknya pengaruh penggunaan Lembar Aktivitas Siswa (LAS) berbasis metode penemuan terbimbing terhadap kemampuan representasi matematis siswa SMP. Penelitian ini merupakan penelitian quasi eksperimen dengan Pretest Posttest Control Group Design. Penelitian ini dilakukan di SMPN 3 Rambah pada siswa kelas VII. Data yang dikumpulkan adalah data peningkatan kemampuan representasi matematis siswa. Instrumen yang digunakan adalah soal essay yang disusun berdasarkan indikator kemampuan representasi matematis. Hasil analisis data menggunakan uji Mann Whitney diperoleh nilai Zhitung yaitu 2,13 dan nilai Ztabel yaitu 1,96. Hal ini berarti Zhitung > Ztabel dengan demikian sesuai kriteria penguhian hipotesis, Ho ditolak. Oleh karena itu dapat disimpulkan bahwa ada pengaruh yang signifikan penggunaan LAS berbasis metode penemuan terbimbing terhadap peningkatan kemampuan representasi matematis siswa SMP. The Effect of Use of Student Activity Sheets Based on Guided Discovery Method on Increasing Students Mathematical Representation Ability AbstractThis study aims to determine whether or not the influence of the use of Student Activity Sheet (SAS) based on guided discovery methods on the mathematical representation ability of junior high school students. This research was a quasi-experimental study with Pretest Posttest Control Group Design. This research was conducted at SMPN 3 Rambah in class VII students. The data collected was data on improving students mathematical representation abilities. The instrument used was an essay test which was arranged based on indicators of mathematical representation ability. The results of data analysis using the Mann Whitney test obtained a calculated value of 2.13 and a Ztable value of 1.96. This means that Zhitung> Ztable is thus according to the criteria of hypothesis testing, Ho was rejected. Therefore, it can be concluded that there is a significant effect of the use of SAS based guided discovery method on improving the mathematical representation ability of junior high school students.

The Difference

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.

In some traditional large-class classrooms, there are problems such as inactive teaching process and poor teaching pertinence, which makes some students who are easily distracted and have the poor receptive ability cannot keep up with the teaching progress and gradually become students with learning difficulties. This research method using pretest-posttest control group design. The sample of this research is the experimental class method there are 48 students and in the control class 48 students grade 7 junior high school students. based on the results, Micro-classes have the characteristics of short, compact and powerful, which can effectively help students with learning difficulties to learn and master mathematics efficiently within the effective learning time. Based on the characteristics of students with learning difficulties and micro-classes, the author explores the actual improvement effect of micro-classes on the mathematics learning of students with learning difficulties by designing micro-classes in a targeted manner and conducting comparative teaching experiments in the first two parallel classes.

Redox contains concepts that are quite difficult to understand the students, because it involves chemical reactions, concepts that are abstract and tiered. The findings in the field also shows contextual learning and yet still shows its application in technology or phenomena in their daily lives. This happened at Muhammadiyah kedawung high school students, 75% of students declared incomplete on redox material. Character building has not been fully applied in learning. Experimental design used was pretest - posttest control group design. Tests performed twice, ie before and after treatment both in the experimental class and control class. Data collection techniques using the methods of documentation, observation, tests, interviews and questionnaires. Based on the results of t-test showed that there are differences in learning outcomes in redox material before and after treatment both in the experimental class and the control class. Experimental class learning outcomes increased by 81.39% and 45.45% control class. This learning model also affect the growth of honest character, responsibility and caring environment students although the increase is considered low. The students' response to learning analyzed qualitatively gained an average of 79.33 with very good category.

Inquiry-based science issues approach facilitates the development of scientific skills through research activities on surrounding science issues. The purpose of this research was to understand the influence of Inquiry-based science issues on practical skills of Junior High School students. This research employed quasi-experimental research method, equipped with pre-test, post-test non-equivalent control group design. The sample of sixty junior high school students in Yogyakarta was picked for this study.  The instruments used were observation sheets on practical skills, practical skills test, and instructional learning sheets. The data collected were analyzed using N-Gain, percentage, and Analysis of Covariate (ANCOVA) at 0.05 significance level. The result revealed that Inquiry Science Issues was more effective in fostering students’ practical skills than the scientific approach. There was a significant effect of treatment on students’ practical skills while no interaction between approach and prior knowledge of students. Moreover, the data of practical skills through the observation sheets in the experimental class had higher percentage compared to the control class, 80.36%, and 70.61% respectively.
