Abstract

Students’ low conceptual understanding in science learning remains a persistent challenge, often caused by teacher-centered approaches that limit active engagement and meaningful learning experiences. This study aims to examine the effect of the Inquiry learning model on students’ conceptual understanding in science at SMA Negeri 1 Lotu. The research employed a quasi-experimental design using a randomized pretest-posttest control group approach. A total of 52 eleventh-grade students participated in the study, divided into an experimental class taught using the Inquiry model and a control class taught using conventional methods. Data were collected through essay-based tests administered before and after the intervention and analyzed using descriptive and inferential statistics, including an independent t-test. The findings reveal that students in the experimental group demonstrated a higher improvement in conceptual understanding compared to those in the control group. The mean posttest score of the experimental class was significantly higher, indicating the effectiveness of the Inquiry model in facilitating deeper conceptual learning. The statistical analysis further confirmed a significant difference between the two groups, supporting the hypothesis that Inquiry-based learning positively influences students’ understanding of science concepts. These results highlight the importance of student-centered learning approaches in enhancing both cognitive outcomes and scientific thinking skills.

Abstract

The development of critical thinking skills has become a central objective in higher education, particularly in science education, where students are expected to analyze information, evaluate evidence, and make reasoned judgments. However, many university students continue to demonstrate limited critical thinking abilities during the learning process. This study aimed to examine the effectiveness of inquiry-based science learning in enhancing students’ critical thinking skills in the Scientific Learning course. The study involved 20 sixth-semester students enrolled in the Biology Education Study Program at Universitas Nias and employed a one-group pretest–posttest design. Critical thinking skills were measured using a test instrument developed based on Facione’s (1990) critical thinking indicators. The findings revealed a substantial increase in students’ average scores, rising from 54.8 in the pretest to 81.4 in the posttest. The paired-sample t-test produced a significance value of p = 0.000 (p < 0.05), indicating a statistically significant difference between pretest and posttest scores. The overall N-gain score of 0.59 was categorized as moderate, with improvements observed across all critical thinking indicators, although self-regulation showed the lowest gain. These findings demonstrate that inquiry-based science learning effectively enhances university students’ critical thinking skills while highlighting the need for further attention to self-regulation development.

Abstract

Digital transformation in education requires teachers to be capable of integrating technology into the learning process. However, in reality, the utilization of digital media in schools remains suboptimal, particularly in the use of Augmented Reality (AR)-based learning media. This study aims to analyze the optimization of teachers’ competencies through AR-based learning media training at SMP Negeri 3 Sitolu’ori. The study employed a quantitative descriptive approach with a hands-on practice-based training design. The research subjects consisted of 19 teachers from various subject areas selected using purposive sampling techniques. Data were collected through observations, questionnaires, interviews, and documentation, and were analyzed using descriptive statistics and interactive analysis. The results showed that all research instruments were valid and highly reliable, with Cronbach’s Alpha values of 0.973 and 0.981. Most teachers demonstrated positive perceptions toward the use of AR media, with 87% categorized as good and very good. The training was also considered effective in improving teachers’ readiness, understanding, and confidence in developing technology-based learning. The findings indicate that AR media has significant potential to support interactive and innovative learning, although its implementation still faces challenges related to limited devices and the technical abilities of some teachers.
