This study aimed to ascertain students' mental models while learning about salt hydrolysis through augmented reality (AR). The study comprised 36 participants from Public High School 51 in Jakarta. A descriptive qualitative approach was adopted for this research, employing various data collection methods such as written drawings, interviews, classroom observations, teacher notes, student worksheets, and final tests. In categorizing students' mental models, three main types emerged: scientific, synthetic, and initial mental models. The findings revealed that 7.20% of students fell into the initial mental model category, 53.90% exhibited synthetic mental models, and 38.90% demonstrated scientific mental models. Notably, incorporating AR into salt hydrolysis learning predominantly influenced the development of synthetic mental models. The study's results also indicated that the utilization of AR positively enhanced students' spatial abilities in understanding submicroscopic representations.

This research was motivated by students who observed low interest in science learning, negatively affecting their cognitive learning outcomes. The issue stems from the conventional, teacher-centered lecture method, resulting in one-way communication that causes students to become bored and disengaged. This study aims to enhance students' interest in learning by implementing the Problem-Based Learning (PBL) model supported by visual media for 5th-grade students at elementary school SD Negeri 100706 Padang Lancat in Padangsidimpuan City, North Sumatra, Indonesia. This research employs a collaborative Classroom Action Research approach with homeroom teachers. Data collection involved observation sheets and questionnaires. The findings indicate that the PBL model assisted by visual media significantly increased students' interest in learning science. Initial data revealed that only 26.67% of students were categorized as having a good interest in learning. In Cycle I, this percentage increased to 60%, and in Cycle II, it further rose to 87%, with students categorized as having good and very good interest in learning.

This study aims to analyze student activity in flipped learning environments and their response to chemistry learning. The variations of digital media used in this research are YouTube, Miro, Wizer.me, Quizizz, Google Form, and Google Classroom. Participants are 11th grade public high school in Depok city, West Java, Indonesia. The method used is a descriptive qualitative method with data collection techniques through observation sheets, teacher diaries, interviews, reflective journals, and student activity questionnaires. The activity questionnaire in this study used StRIP, adapted from DeMonbrun, et al. Activity indicators consist of two dimensions: student response to instruction and instruction type dimensions. Student activity data is processed using a Likert scale. The results showed that the majority of students responded positively to the second dimension. The results showed that students' responses to instructions and types of instructions developed well during the learning process. This is consistent with the results of the student questionnaire data, which shows a percentage of >70% in each dimension. The affective domain shows that some students have a good attitude of responsibility and discipline. They actively express their opinions and work together in groups. In the psychomotor domain, the students show that they are careful in carrying out and compiling the practicum reports. This study concludes that the flipped classroom learning model using various digital learning media can help develop students' activities in chemistry learning.

This research analyses the flipped classroom learning model on students' mental model on salt hydrolysis material. This research was conducted at SMAN 1 Ulu Barumun, Padang Lawas Regency. The research subjects were 11th-grade science students, totalling 20 students. The study used a two-tier test instrument, student observation, and in-depth interviews. The results showed that most students achieved the scientific mental model (38.33%), which reflects deep understanding and the ability to connect concepts with phenomena scientifically. In addition, 31.52% of students were at the synthesis mental model, where they began to understand the concept, but there were still misconceptions. Meanwhile, 30.13% of students were in the initial mental model, with limited and inaccurate understanding. Factors such as teacher explanation, learning experience, and learning resources used play an important role in achieving the scientific mental model. Overall, flipped classrooms are proven to be an effective learning strategy and are worth applying to improve the quality of learning and form students' mental models on salt hydrolysis material.

Understanding stoichiometry remains a significant challenge for many secondary school students, primarily due to traditional instructional approaches that emphasize memorization rather than analytical reasoning. To address this issue, this study examines the effectiveness of a socio-scientific issue (SSI)-based problem-based learning (PBL) model in fostering students’ critical thinking skills in stoichiometry instruction. The research employed a quasi-experimental design with a non-randomized pretest–posttest control group structure. Participants consisted of two grade X classes from SMAN 1 Sipirok, with one class assigned as the experimental group receiving SSI-based PBL instruction and the other as the control group receiving conventional teaching. Data were collected through essay tests designed around Ennis’s twelve critical thinking indicators. The results of an independent samples t-test indicated a statistically significant difference in posttest scores between the two groups (p = 0.027, p < 0.05), demonstrating that the experimental group outperformed the control group in critical thinking. These findings suggest that integrating socio-scientific issues into problem-based learning can effectively enhance students’ reasoning, engagement, and conceptual understanding in chemistry education. The study contributes to the ongoing discourse on innovative pedagogies by highlighting the pedagogical potential of SSI-based PBL for cultivating higher-order thinking skills in science classrooms.

This research aims to integrate agroindustry and sustainability development into chemistry learning through the Project-Based Learning model (PjBL) to improve the competence of preservice chemistry teachers. This research employed the qualitative method. The Summer Course program was held collaboratively by Universitas Negeri Jakarta, Institut Pertanian Bogor, and Villanova University. The program was implemented online within six weeks due to the COVID-19 pandemic. The participants consisted of 25 students. The data had been collected through interviews, questionnaires, observations, student portfolios, and reflection journals. Based on the analysis, several projects developed by preservice chemistry teachers increased the application to solve sustainability problems in the agroindustry field. Furthermore, the project was expected to be developed into a natural product that can increase the agroindustry value for coffee farmers. The findings also foster the preservice chemistry teachers to improve their creative thinking, collaboration, higher-order thinking skills, and problem-solving skills. Besides, they developed their communication and collaboration after participating in the program. The paper outline is a project development learning experience in a sustainable field and would be a good resource for student-teacher involvement in teacher education.
