Abstract

Buffer solution material was chosen in the process of developing an instrument based on multiple representations, because the buffer solution material contains many representations. Buffer solution material requires explanations in various forms of representation that can visualize the buffer solution material so that students are expected to be able to observe the symptoms that occur and analyze and draw more comprehensive conclusions. This study aims to measure students' conceptual understanding of buffer solution material based on aspects of material, language, construction, and conceptual understanding. The method used is Research and Development with the ADDIE model, involving two schools, SMAN 1 and SMAN 7 Pekanbaru. The validation results by three expert lecturers showed Aiken's (V) values ranging from 0.88-0.97, with instrument reliability stated as good (Cronbach's alpha = 0.815). The level of difficulty of the questions consisted of 4% easy, 84% moderate, and 12% difficult. Measurement of conceptual understanding in 50 students showed a significant difference with a significance value of 0.012 <0.05, so H0 was rejected. The assessment instrument was declared valid and reliable for buffer solution material.

Abstract

The research has been conducted to figure out the use of virtual laboratories on students' conceptual understanding of acid-base titration subject at SMAN 1 Tambusai. The study was an experimental research with one group pretest-posttest design. The sample consisted of one class, XI IPA2, a class that was treated with a virtual laboratory. The data analysis technique used was the t-test. Based on the results of the final data processing using the t-test, it was obtained that sig 5 ≤0.05; where 0,000 ≤ 0.05; so it was concluded that there were significant differences between the mean scores of the pretest and posttest. This shows that there is an increase by the use of virtual laboratories towards the students' conceptual understanding.

Abstract

Efforts to improve the quality of Integrated Science learning for junior high schools in the era of globalization that are following the challenges of 21st-century education can be done through the use of connected type interactive e modules. The study was conducted to determine the effectiveness of the e-module on students' mastery of energy concepts. The research method used is a descriptive quantitative quasi-experimental type with a matching-only pretest posttest control group design. The research was conducted in one of the public junior high schools in Bangkinang with a purposive sampling technique. Data were collected using research instruments in the form of mastery of concepts in energy material. Data analysis was performed using pre-requisite test, statistical test (different test; t-test), and N-Gain test. The results obtained show that the use of the connected type of integrated science interactive e module can improve students' mastery of concepts on energy material in the experimental class with the medium category.

Abstract

The importance of practical implementation, especially in science subjects, is challenging for educators, students, and schools. Many findings are related to various obstacles and problems regarding implementing practicum in the laboratory, so the implementation is considered ineffective. This research aims to determine students' perceptions of implementing practicum in the science laboratory. This study used a survey method with a quantitative approach involving 96 respondents, consisting of 48 students in 8th grade at Junior High School 1 Kuantan Hilir and 48 students in 8th grade at Islamic Junior High School 1 Sentajo Raya. The instrument used was a questionnaire consisting of 26 statement items. The data collection technique was done by distributing questionnaires directly and then conducting descriptive analysis. The results of this study indicate that students' perceptions of the practical implementation in the science laboratory are in a good category (72.50%). In general, the practical implementation in the science laboratory for grade 8 students at Junior High School 1 Kuantan Hilir and Islamic Junior High School 1 Sentajo Raya has been carried out well. It can be concluded that students have a good perception of the implementation of practicum in the science laboratory.

Abstract

This research was motivated by the difficulty of students in understanding the concepts in chemical material. The goal of this research is to see the differences in learning outcomes between students who are given two different learning models and see it from Goal Oriention (GO) factors owned by students. This research was conducted at SMA Muhammadiyah 01 Pekanbaru City. The variables in this study were the Learning Model and GO characters (independent variables) and chemistry learning outcomes (the dependent variable). The results of data analysis on One Way Anava was a sig. 0.02 for the application of two learning models and the Independent Sample T-Test obtained sig. 0.02 and sig. 0.32. Based on data analysis, it was concluded that student learning outcomes with those taught with the DL model were better than students taught with the PBL model. Learning outcomes MGO students who are taught with the DL model are better than those taught with the PBL model and there is no difference in the learning outcomes of the PGO students who are taught with the PBL learning model with students who are taught using the DL model.
