Abstract

This descriptive research aims to identify the learning styles of grade 11 high school students in science major on chemistry learning and measure the level of optimization of teachers and students regarding the use of Augmented Reality-based chemistry learning media. This research was conducted on 9 chemistry teachers and 90 students majoring in science in Toraja Utara Regency. Data collection has been done using a closed-ended questionnaire with 4 choices consisting of 25 statements for chemistry teachers and 18 statements for science major students. The data were analyzed using a percentage formula and the results obtained showed that teachers had not optimized the use of Augmented Reality as a chemistry learning media. Furthermore, the most common learning style of students is visual, followed by kinesthetic and then auditory

Abstract

This quantitative research focuses on defining the profile of students’ Higher Order Thinking Skills (HOTS) using Two-Tier Multiple Choice Test (TTMCT) instrument. The research carried out in SMAN 2 Toraja Utara, Indonesia. From the entire 11th grade science, 109 students were chosen as participant by purposive sampling. TTMCT consisting of 15 questions about acid base concepts with the cognitive domains of analyzing (C4 and evaluating (C5) was used. Before its implementation, the test underwent a rigorous validation and reliability process. The validation provided confidence in the instrument's ability to effectively measure the intended variables and The Cronbach's alpha coefficient of this instrument is 0.71. This study presents two comprehensive results: firstly, students’ HOTS profile is dominated in good category with an average score of 63.83, and secondly, the comparison of cognitive level: analyzing (C4) with the mean percentage is 71.32% then evaluating (C5) cognitive level with the mean percentage is 60.80%.

Abstract

Metacognitive awareness is essential in fostering students' ability to regulate their own learning processes, especially in complex subjects like analytical chemistry. This study investigates the effectiveness of a Problem Based Learning (PBL) model assisted by Blended Learning in enhancing metacognitive awareness among university students in the topic of UV-Vis spectroscopy. Using a quasi-experimental design, two groups were compared: an experimental group receiving PBL combined with Blended Learning, and a control group receiving conventional PBL. Data collection involved pretest and posttest cognitive assessments, metacognitive awareness questionnaires, and observation of student engagement on the Edmodo platform. The results demonstrate significant improvement in the experimental group’s posttest cognitive scores (mean = 85.59) compared to the control group (mean = 77.37), with effects also observed in metacognitive awareness and self-regulation skills (p < 0.05). These findings suggest that integrating Blended Learning into the PBL framework can effectively enhance cognition, metacognitive skills, and student motivation in chemistry education. The study encourages the adoption of this blended instructional strategy and further research on its wider applicability.
