Abstract

This study aims to improve student learning outcomes through the implementation of contextual approaches based on learning community in SMP Negeri 3 Tanjung in 2017/2018 Academic Year. This research is a classroom action research. Actions are carried out through two cycles, each cycle consisting of the process of planning, implementation, observation, and reflection. The instrument used was a multiple-choice test instrument. The subjects of this study were 26 students of class VIII-4 of SMP Negeri 3 Tanjung. The results of the study showed that in the cycle I the percentage of completeness of student learning outcomes was 76% with an average score of 74.23, while in the cycle II the percentage of completeness of student learning outcomes was 92% with an average score of 85.34. Based on the results of the study it can be concluded that the implementation of contextual approaches based on learning community can improve student learning outcomes.

Abstract

Science learning carried out by teachers mostly uses conventional methods and rarely uses media in the activities of their teaching and learning process. Media mind mapping in physics learning can be used to describe a lot of material and can package it to be more interesting. The aim of this research to determine the effect of mind mapping media toward the students? concept understanding. This study used quasi-experimental research with pretest and posttest control group design. The population used was all students of class X in SMA Negeri 1 Lingsar at 2018/2019 Academic Year. The number of samples are 32 students for the experiment class and 33 students for the control class taken by purposive sampling technique. Data analysis technique used is the t-test using IBM SPSS Statistics 22. Based on the results of hypothesis testing (t test), it is known that the significance value of the posttest data (0.00) is smaller than alpha testing (0.05), so it can be stated that the mind mapping learning method influences the students' understanding of concepts.

Abstract

The purpose of this study is to improve the students? activity and learning outcomes through the implementation of the POE learning model with the assistance of student worksheets. The research subjects were 22 students? grade of VIII SMP Negeri 4 Batukliang Utara. This type of research is classroom action research (CAR), which is carried out in two cycles. Each cycle consists of four stages, namely planning, implementation, observation/evaluation, and reflection. The implementation of the POE learning model is carried out through three stages, namely Predict, Observe, and Explain stages. The measured variable is the activity and learning outcomes on the subject matter of Motion. Research data collection techniques using observation sheets and tests. The results of the study in Cycle I obtained an average score of student learning activities is 2.08 with the category of quite active and the average value of students? learning outcomes is 73.41 with classical completeness of 54.55%. In cycle II the average score of students? learning activities is 2.95 with the actively category and the average learning outcome is 83.41 with a classical completeness of 86.36%. Based on the results of the study it was found that the implementation of the POE learning model with the worksheets assistance could improve the students? activities and learning outcomes grade of VIII SMPN 4 Batukliang Utara.

Abstract

The role of education is to improve the quality of education, especially in producing high-quality students. High-quality students are those who are able to think critically, creatively, logically and take initiatives in responding to issues in society caused by the impact of the development of science and technology. This study aims to determine the effect of a scientific approach to students' critical thinking skills. This study is an experimental research with one group pretest-posttest design. The sample of this study consisted of one class (28 students), which was treated using a scientific approach. Critical thinking skills are measured using a test instrument and then analyzed statistically (t test). Hypothesis test results indicate that there is an effect of using a scientific approach toward students' critical thinking skills.

Abstract

This study aims to determine the effect of inquiry learning models with pictorial riddle methods on students' creative thinking abilities. This research is a quasi-experimental (Quasy Experiment) with Nonequivalent Control Group Design. The research sample consisted of two classes, namely class X IPA 2 and class X IPA 3, each of which amounted to 30 students. The creative thinking ability test instrument consisting of 12 items and observation sheets was used to collect data in this study. The results of the study were analyzed using SPSS v-22 software for windows. The results showed that: 1) the average initial test scores of the experimental and control classes were 45.7 and 44.1 respectively; 2) the average initial test scores of the experimental and control class were 79.2 and 68.8 respectively; 3) homogeneity prerequisite tests show homogeneous data and normality tests show normally distributed data; 4) t-test results obtained Sig. (2-tailed) posttest data (0.00) is smaller than alpha testing (0.05), so the working hypothesis (Ha) is accepted. Thus, the inquiry learning model with the pictorial riddle method influences students' creative thinking abilities.
