Abstract

One of the subjects that plays an important role in the development of the times is science. Science subjects aim to equip students with knowledge related to everyday life and train them to think scientifically. Therefore the call for learning objectives in science is something that needs to be prioritized by the teacher. One of the steps that can be taken by the teacher is to apply a learning model that is in accordance with the characteristics of the material in science subjects. One model that can be applied by teachers is the STD type of cooperative learning model. The purpose of this study was to see the effect of the STAD type cooperative learning model on students' cognitive learning outcomes on temperature, heat and expansion of SMPN 28 Padang.This research is a type of quasi-experimental research with nonequivalent control group research design. The sample in this study used a purposive sampling technique. Statistical analysis in this study used SPSS version 25. Based on the hypothesis test, a significance value of 0.735 was obtained, which means that there was no effect of the STAD type cooperative learning model on students' cognitive learning outcomes on temperature, heat, and expansion for class VII SMPN 28 Padang. There are several inhibiting factors on students' cognitive learning outcomes including student character, student interest in learning, various student backgrounds, students' basic mathematical abilities and model adjustments that have just been implemented at SMPN 28 Padang.

Abstract

The purpose of this study was to determine the difference in science learning outcomes between groups of students who participated in learning with the Reading to Learn (R2L) model and direct learning, by analyzing the literacy skills of class IX students at Junior High School in Bukittinggi, West Sumatra. The study population was all students of class IX and the sample class was selected by purposive sampling technique, so that class IX-6 was obtained as the experimental group and class IX-4 as the control group, with a sample of 56 students. This research is a quasi-experimental research with a pretest and posttest group design pattern. The data collected is a test of learning outcomes which are analyzed quantitatively to measure students' scientific literacy skills which are grouped into 3 aspects, namely numerical, conceptual, and multidimensional aspects. The instrument used is a scientific literacy test in the form of 10 description questions. The results show that the research hypothesis H1 is accepted because the table shows that t count > t table. This hypothesis test found that the application of the Reading to Learn (R2L) approach had an effect on students' scientific literacy skills. While the results of the experimental group N-Gain was 0.44 or 44% in the medium category (less effective). So we look at some of the factors causing it by giving questionnaires to students. Based on statistical calculations, the scores for each indicator in the questionnaire are 87.5% of students using local languages in daily conversation, reading time of 10-30 minutes is 46.88%, and courses or tutoring outside school hours are 28.13%.

Abstract

The education of the natural sciences is closely linked to environmental issues. One of the most accurate models used is the problem-learning model. This study aims to look at the impact of a problem-based learning model. With a contextual approach to the competence of high school students, this research is an experimental study using a non-equivalent group design. Based on statistical analysis of the cognitive, psychomotor, and affective aspects of the students, it is known that the data is distributed normally but homogeneously. Then the hypothesis was tested using an independent t test, with the result of the H0 hypotheses rejected. It is understandable that a problem-based learning model with a contextual approach has a significant influence on the competence of high school students. Based on the results of the research, it can be concluded that to enhance student competence, the teacher plays an important role in implementing problem-based learning as it can improve learning outcomes in various aspects, including cognitive, psychomotor, and affective. Then one of the recommended models is problem-based learning (PBL) with a context-based approach.
