Abstract

The spectrum emitted by electromagnetic wave radiation has various frequencies, one of which is Extremely Low Frequency (ELF), and is often found in educational environments, originating from various electronic devices, high voltage electrical panels, and internet network supporting devices. Based on this description, it is necessary to measure ELF electromagnetic radiation in the Faculty of Mathematics and Natural Sciences environment at Universitas Negeri Gorontalo. This research was carried out by measuring magnetic field values (µT) at 42 location points using a Portable Electromagnetic Field Tester (EMF Tester). The research results show that all of these location points are within the safe threshold based on ICNIRP and WHO regulations, namely below 200 µT, with the highest ELF magnetic field value is 2.81 µT, and the lowest ELF magnetic field value is 0.003 µT. However, there are several studies showing that exposure to ELF electromagnetic field radiation can produce free radicals, causing cell damage. The results of this research can be used as a basis for making health policies for the Faculty of Mathematics and Natural Sciences academic community at Universitas Negeri Gorontalo.

Abstract

Students' learning needs need to be considered when teaching in the classroom. Implementation of differentiated learning is one of the teaching applications that pays attention to students' needs. The study aims to design static electricity learning devices with a differentiated approach in facilitating inclusive education. The study is part of the development of learning devices consisting of three stages, namely: preliminary stage, development stage and implementation stage. The results show a valid value teaching module with an average value of 81.25 including the valid category. In the implementation, a trial of differentiated learning devices was carried out through teaching in class IX. At this stage, information was obtained on the value of the implementation of learning implementation above 90 including the Very High category. Likewise, student learning outcomes at this implementation stage increased with an N-Gain value of 0.578 including the moderate category. The effect size test value was obtained at 6,510 including a strong effect. This shows that the implementation of the differentiated learning device design has a strong effect on static electricity learning outcomes. The conclusions of the study were obtained as follows: (1) the design of differentiated learning devices assessed by experts and practices is valid; (2) the implementation of the differentiated learning device design is included in the high category, there are two students who have obstacles in the form of slow learners at the regular school which is the trial location; (3) the design of the differentiated learning device which is arranged effectively is shown by the N-Gain value in the medium category and the effect size value in the strong effect category

Abstract

Scientific literacy is an individual's ability to apply scientific knowledge, identify questions, and draw conclusions based on evidence to understand and make informed decisions about the natural world and changes resulting from human activities. This study aims to analyze the effectiveness of interactive learning media based on the Virtual Laboratory in enhancing scientific literacy and improving students' conceptual understanding of the Dynamic Electricity. The study employed a quasi-experimental design, specifically the One-Group Pretest–Posttest Design, without a control group. The research subjects consisted of four ninth-grade students from two schools, namely SMPN 3 Pagimana and SMPN 5 Pagimana, totaling 80 students. The research instruments consisted of a science literacy test and a concept mastery test, each consisting of 10 essay questions and validated by experts. The results showed that the use of Virtual Laboratory media effectively improved students' science literacy, as indicated by a significant increase in scores on the posttest compared to the pretest. Statistical analysis using a paired sample t-test yielded a significance value < 0.05 in all classes, indicating a meaningful difference between students' initial and final abilities. Furthermore, the Normalized Gain (N-gain) value was in the high category (0.93–0.97). Thus, interactive learning media based on Virtual Laboratories have proven effective in improving students' science literacy and concept mastery of the Dynamic Electricity, and can serve as an alternative solution in science learning in schools with limited laboratory facilities

Abstract

Implementing interactive learning media based on virtual laboratories is efficacious in improving students' scientific literacy in science learning. This study aims to assess the effectiveness of using interactive learning media based on virtual laboratories in improving students' scientific literacy and science process skills in dynamic electricity in two schools, namely SMP Negeri 1 Kwandang and MTs Al-Khairaat Kwandang, using a guided inquiry learning model. The research design employed was a quasi-experimental design with a pretest-posttest control group. Data was obtained through scientific literacy tests and observation sheets for science process skills. The study's results showed that interactive learning media based on virtual laboratories were effective in enhancing students' scientific literacy and science process skills. The results of the N-Gain analysis for scientific literacy showed an average score of 0.72, indicating a high category. Meanwhile, the results of the observations showed an increase in the achievement of science process skills at each meeting, particularly for the indicators of observing and conducting experiments, which improved to the very good category. Additionally, the results of the t-test on scientific literacy revealed a statistically significant difference (p < 0.05), indicating a significant difference between the pre- and post-learning periods. Thus, interactive learning media based on virtual laboratories assisted by guided inquiry models have been proven effective in improving students' scientific literacy and science process skills

Abstract

This research aims to determine the influence of the Problem-Based Learning (PBL) model to student learning outcomes on heat and transfer concepts by using experimental research, with the research design being One Group Pretest-Posttest Design. The population of this study was class VII students of SMP Negeri 5 Gorontalo. The sample consists of 3 classes, namely experimental class, replication 1, and replication 2, with the sampling technique being Cluster Random Sampling. The instrument of research used was a learning outcomes test in the form of a pretest-posttest to see student learning outcomes. Then, the data was analyzed using descriptive and inferential statistics, including normality tests, hypothesis tests, and n-gain analysis. The average score for class VII students is greater than the Criteria for Achieving Learning Goals, shown by an average score for the experimental class of 82.25, replication 1 of 79.94, and replication 2 of 79.04, compared to the Criteria for Achieving Learning Goals of 70. Based on the hypothesis testing criteria for the class, experimental Tcount 7.036 is greater than Ttable 2.035, replication 1 Tcount 6.684 is greater than Ttable 2.035, and replication 2 Tcount 5.824 is greater than Ttable 2.035 so it stated Tcount is more prominent than Ttable. This can be interpreted that the PBL model influences student learning outcomes.
