Abstract

The study aims to evaluate the effectiveness of the Problem-based Learning model in improving the students' ability to collaborate on practical activities related to the solution colligative properties. The research design uses quasi-experimental methods with control groups and experiments. The study sample consisted of 60 XI IPA class students selected using purposive sampling techniques, with 30 students in the experimental group and 30 in the control group. The research instruments include a test of collaborative abilities, a sheet of observations on collaborative activities, and an elevator of student responses. The results showed that the average pre-test scores of students' collaboration ability in experimental and control groups were relatively the same. Still, there was a significant improvement in the experimental group's post-test score after applying the Problem-Based Learning model. The pair t-test results showed a substantial improvement in both groups, but the increase in the experimental group was significantly higher (t(30) = 12.45, p < 0.05) compared to the control group (t(30) = 3.21, p < 0.05). Independent t-tests showed significant differences between the experimental and control groups after treatment (t(60) = 6.34, p < 0.05). Observations during the practice showed that students in the experimental group were more active in communicating, sharing tasks, collaborating, and solving problems than in the control group. In addition, the student response raise showed that the majority of students responded positively to the Problem-Based Learning model, with a high average score on interesting and enjoyable aspects (4.5), boosting motivation (4.6), facilitating the understanding of concepts (4.4), and enhance the ability to collaborate (4.7).

Abstract

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.

Abstract

PISA results for 2022 report that Indonesian student's numeracy skills have improved. However, the results are still below the global average and require continuous improvement. One attempt to enhance student's numeracy skills is by providing numeracy-based assessments that can be applied to chemistry subjects, one of which is stoichiometry. The study aims to identify and describe the numeracy profile of eleventh-grade high school students on stoichiometry. The method used is quantitative descriptive. The study subjects were eleventh-grade high school students who had received stoichiometry instruction. The instruments used consisted of nine questions that were validated and empirically tested (reliability score of 0.528, indicating a fairly reliable category). The study results showed that the students' numerical abilities obtained an average score of 67%, which was categorized as good. The percentage of students in the excellent category was 26%, in the good category was 47%, in the sufficient category was 24%, and in the less-than-sufficient category was 3%. The indicator accuracy rate was 61% for analyzing information such as tables, charts, and diagrams, 80% for using numbers and symbols, and 56% for interpreting analysis results. Numeracy skills in chemistry, particularly in stoichiometry, are crucial for achieving learning objectives and supporting global efforts toward quality education, as aligned with the SDGs. Enhancing these skills equips students with better problem-solving abilities in academics and real-life situations.

Abstract

The assessment conducted by PISA indicates that the science literacy rate of students in Indonesia occupies the lowest rank. One of the reasons is the lack of literacy-based assessments with multiple representations. This study aims to describe the profile of science literacy skills of eleventh-grade students on base acid material. The method used is descriptive quantitative, with the subject of the study being 62 students in XI grade who have acquired base acid matter. The instrument used is 10 elements of scientific literacy description with a multiple representation framework developed, with a high-reliability value of 0.795. The study results showed that the average literacy profile of science students reached 56.22%, which belongs to the middle category, with 5% of students entering the lower category, 27% in the high category, and 68% in the medium category. Students' access to indicators explaining scientific phenomena reached 52.29%, interpreting data and evidence scientifically reached 54.96%, and evaluating and designing scientific research reached 83.3%. Based on these data, eleventh-grade students have a moderate level of science literacy, with the highest access to the indicators to evaluate and design scientific research. This literacy of science needs to be enhanced through the provision of scientific literacy tools that apply multiple representations.

Abstract

Applying the learning model should encourage students to learn actively, think, and use their abilities to discover. Apart from that, learning linked to the SSI context can also support functional scientific literacy skills. StudyThis aims to analyse the influence of the discovery learning model in the context of Socio Scientific Issues (SSI) on students' scientific literacy abilities and cognitive learning outcomes on Basic Laws of Chemistry material. This research uses a quasi-experiment method with a control posttest-only group design—research population of class X students at MAN 10 Jombang. Sampling used the purposive sampling technique, which consists of two classes: the experimental class, which applies the SSI-based discovery learning model, and the control class, which uses discovery learning. Data collection used a 10-item essay test instrument to measure scientific literacy skills and a 15-item multiple choice test to measure cognitive learning outcomes. Both have been validated; the reliability was 0.869 and 0.889, respectively—data analysis using a t-test. The results of the research show that there is an influence of the SSI-based discovery learning model on scientific literacy skills with a 2-tailed sig value of 0.031 80,56.

Abstract

Learning in Indonesia currently still focuses on theoretical knowledge, so that the implementation of Education for Sustainable Development (ESD) is not optimal. Chemistry is a suitable subject to teach sustainable principles in accordance with ESD principles, especially on the topic of reaction rate. However, there are problems for students in understanding the reaction rate, as evidenced by students' concept understanding of this material being only 26%, and only 33.3% of students managed to get a score above the KKM. These problems can be caused by the limited learning media that facilitate students in learning the reaction rate. Therefore, this research aims to develop educational kit-based learning media on reaction rate material with the Socioscientific Issues (SSI) approach integrated with augmented reality technology as an effort to support ESD. This research method uses Research and Development (RnD) level 1 with five stages, namely potential and problems, literature study and information gathering, product design, design validation, and tested design. The results showed that the learning media presented in the form of educational kits with the SSI approach equipped with mobile applications, game cards, flashcards, and practicum kits with the concept of green chemistry have been produced. This product is a suitable educational media in an effort to improve the quality of education through the implementation of ESD.
