Abstract

This study examines the profile of science process skills and scientific attitudes among students in Nunukan Regency. The study population includes 9th-grade students from junior high schools during the 2023/2024 school year. The research involved 243 students to evaluate science process skills and 332 students to assess scientific attitudes through questionnaires spanning 21 different schools. The research type is descriptive quantitative with the sampling technique being conducted through accidental sampling. The study administered 27 questions on electrical circuit material and a scientific attitude questionnaire with 40 statement items using a Likert scale. The results show that (1) varying levels of science process skills: observing (40%), classifying (39.4%), predicting (30.87%), planning experiments (40.6%), formulating hypotheses (40.2%), interpreting data (38.4%), implementing concepts (38.7%), measuring (37.3%), and communicating (36.2%). The average score for science process skills was 38%, falling into the low category. (2) In contrast, scientific attitude scores were higher: curiosity (71.3%), critical thinking (71.3%), respecting data/facts (63%), open-mindedness (74.1%), cooperation (68.1%), and honesty (72.2%), with an average score of 70%, falling into the high category. (3) The results of the correlation analysis indicate that H0 is rejected, and Ha is accepted. This means there is a significant relationship between scientific process skills and scientific attitude, which is weak but positive.

Abstract

Purpose of the study: The research objective is to provide essential insights into students' self-regulation characteristics in border regions, which can inform strategic efforts to maintain and improve their capabilities as they navigate the challenges of the digital era. Methodology: This study used quantitative research with descriptive data analysis involving 198 students from three junior high schools in Nunukan Regency. Data was collected using a self-regulation questionnaire with a Likert scale, which measured four indicators: forethought, volitional control, motivation, and self-reflection. The data was then analyzed using score and average calculations to assess the students' self-regulation profile. Main Findings: The study findings reveal that the self-regulation profile of junior high school students in Nunukan Regency is generally in the high category, with an average of 77%. The motivation indicator reached the highest level at 81%, while volitional control was the lowest at 72%. Notably, differences in self-regulation levels were observed across the participating schools and grade levels. Novelty/Originality of this study: This study provides a comprehensive understanding of the self-regulation characteristics of students in the border area of Nunukan Regency, which can serve as a basis for developing more effective learning strategies and improving the quality of education in similar contexts. The findings offer valuable insights that can inform the development of targeted interventions and support systems to cater to the specific needs of learners in border regions as they navigate the challenges of the digital era.

Abstract

Purpose of the study: Assessment of students' critical thinking skills and environmental care attitudes is crucial for science learning. This research aims to develop an essay test instrument for critical thinking and a questionnaire for environmental care attitudes, evaluating their validity through expert assessments and trials. Methodology: Utilizing the Research and Development (R&D) model by Oriondo & Dallo-Antoio (1998), the study comprises three stages: test planning, trials, and validation. A random sampling technique was employed, involving 267 students. The critical thinking instrument consists of essay questions, while the environmental care attitudes are measured using a prosocial intentions questionnaire. Main Findings: Validity results indicate a high Aiken index of 0.96 for critical thinking essays and 1.0 for the environmental care questionnaire. Reliability estimates were 0.73 for critical thinking and 0.71 for environmental attitudes, both good. The difficulty level for the critical thinking instrument was classified as medium (0.68), while the environmental care instrument was deemed difficult (1.65). Limitations include focusing solely on science subjects, trials restricted to one area, and reliance on self-reports for environmental attitudes, which may introduce bias. Novelty/Originality of this study: The novelty of this study lies in integrating critical thinking assessment with environmental care attitudes, a rare approach in previous research. In conclusion, the developed instruments effectively measure students' critical thinking skills and environmental care attitudes in science education, particularly regarding global warming.

Abstract

This study aims to determine the scientific attitude level of students at SMP Muhammadiyah 1 Berbah. Using quantitative descriptive research methods, data was collected through scientific attitude questionnaires. The results showed that students' scientific attitude levels varied for each indicator, where curiosity obtained a score of 56 (medium level), critical thinking score 56 (medium level), respect for data/facts score 60 (medium level), open-mindedness score 58 (medium level), cooperation score 61 (medium level), and honesty achieved the highest score of 67 (high level). Overall, the average score of students' scientific attitudes was 59, at a medium level. Percentage analysis showed that no students were at low and very low levels (0%), the majority of students were at medium level with a percentage of 66% (128 students), followed by high level at 33% (64 students), and very high level at 0.5% (1 student).

Abstract

Critical thinking is essential in contemporary times as it trains students to analyze, evaluate, and make logical and reflective decisions. This study aimed to determine the effect of discovery learning integrated with differentiated instruction on students' critical thinking skills. This research employed a pre-experimental method with a one-group pretest-posttest design. The research subjects were 30 ninth-grade students of SMPN 4 Sentajo Raya. Data were collected through pretest and posttest assessments using critical thinking questions on temperature and heat. The results showed that the average pretest score was 48 and the posttest score was 78. Based on the paired samples test with a significance value (2-tailed) < 0.05, the null hypothesis (H₀) was rejected and the alternative hypothesis (H₁) was accepted. This indicates a significant difference in students' critical thinking skills before and after implementing the discovery learning integrated with differentiated instruction.

Abstract

This development was motivated by students' low science process skills and the limited availability of teaching materials that integrate simulation technology in junior high school science learning, necessitating innovation in the form of worksheets that can facilitate discovery-based learning. This research employed the Research and Development (R&D) methodology with the ADDIE model. A pre-experimental design with one group pretest-posttest was used at the implementation stage. The research subjects were ninth-grade students. Data was collected through validation sheets for experts and practitioners, student response questionnaires for readability testing, and science process skills test instruments in multiple-choice questions. Data analysis used quantitative descriptive techniques for validation and readability data, while N-gain test and nonparametric statistical analysis with the Wilcoxon test to analyze product effectiveness. Product feasibility assessment involved media experts, content experts, two practitioners, and 10 ninth-grade students selected through purposive sampling considering different academic ability levels to assess readability. The results showed very high product validity, with average scores of 0.83 from experts and 0.97 from practitioners. The readability test achieved 96%, falling into the excellent category. Product effectiveness was proven high, with an N-gain of 0.85. The Wilcoxon signed-rank test yielded a p-value < 0.05, indicating a significant improvement in students' science process skills. Developing technology-based teaching materials can provide alternative solutions for teachers in integrating virtual practicum into science learning to improve students' science process skills.
