Abstract

This study reports a quasi-experimental investigating the development of Science textbook based on Science Technology and Society for elementary school. The data collection was got from the achievement test (pretest-posttest). The population was all fourth-grade students of elementary schools in Gatak Subdistrict and the sample of the study was two schools as an experimental class and control class. The research sample was taken by random sampling technique. The results of this research showed that there was an improvement of student achievement before and after the implementation of science textbook based on Science Technology and Society. The result of the independent sample t-test shows that tobs is higher than table (5.489>1.681). The outcomes of the learning improvement in the experimental class based on the acquisition of N-Gain scores of 0.558. Based on tobs results, H0 is rejected. So it can be concluded that the development of a science textbook based on Science Technology Society in elementary school is appropriate to use for learning.

Abstract

This research aims to explain 1) the different impact among Numbered Heads Together (NHT) model and direct instruction on the science learning outcomes. 2) the different effect among the high, medium and low self regulated learning on the students’ learning outcomes of science. 3) the interaction among the learning models and self regulated learning towards the students’ learning outcomes of science. The type of research was quasi-experimental research with factorial design 2×3. Population of this research was all students of fifth grade elementary school. The hypothesis test used two-way analysis variant with unbalanced cells. Based on data analysis, Numbered Heads Together model with high self regulated learning was the most effective.

Abstract

Vocational school students are not only required to master competency skills but also cognitive skills. Engineering mechanics learning is a basic calculation lesson that students should master. This research aimed to develop and identify the effectiveness of Android-based virtual laboratory (V-lab) media to improve students’ cognitive skills in learning engineering mechanics at vocational school in Surakarta. The subjects comprised 70 students of first grade vocational school majoring in civil engineering in Surakarta. This research was a research and development (R&D) study to develop an Android-based virtual laboratory media. Testing the N-Gain analysis in the experimental and control classes was to determine the effectiveness of virtual laboratory media in improving students’ cognitive thinking skills. Data were obtained from questionnaires and pretest and post-test test sheets. The developed virtual laboratory media was considered ‘very appropriate’ by media, material, and practitioner experts. The average value of N-Gain for the experimental class was 78.19% which was included in the effective category. Meanwhile, in the control class, the average N-Gain value reached 54.07%, which was included in the less effective category. This indicates that the use of Android-based virtual laboratory media for learning is more effective than conventional learning media.

Abstract

Numeracy skills or numeracy literacy is a basic competency that is important for junior high school students to master in facing the challenges of the 21st century and the Industrial 5.0 era. However, PISA 2023 data shows that Indonesian students are still ranked low in math skills, reflecting students' weak numeracy skills. This study aims to test the effectiveness of Android-based Andro Poster learning media in improving the numeracy skills of grade VII junior high school students. The research uses a pre-experimental quantitative method with a One Group Pretest-Posttest Design. The research sample consisted of 30 students in grades VII-9 of junior high school who were selected through purposive sampling techniques. The research instrument was in the form of a numeracy multiple-choice test of 10 items, which was developed based on indicators of numeracy ability in the submaterial of algebraic forms. Data were obtained through pretest and posttest, then analyzed using paired sample t-tests and effect sizes (Cohen's d). The results showed that the average posttest score (72.87) increased significantly compared to the pretest (60.97), with a p value of < 0.001. The correlation between pretest and posttest of 0.865 shows a very strong relationship. In addition, Cohen's d value of -2.905 indicates a very large measure of effect on students' improved numeracy skills. Andro's Poster Media successfully presents algebra material visually, contextually, and interactively, so that it can increase students' motivation to learn and understand. This study concludes that the use of Android-based learning media such as Poster Andro is an effective and innovative strategy in improving the numeracy skills of junior high school students. This finding is expected to be a practical solution in mathematics learning as well as contribute to the development of digital media that is adaptive to the learning needs of students in the digital era.
