Abstract

The society 5.0  era requires the active contribution of the younger generation to solve problems in the community through implementation of scientific methods which involve integrated science process skills (i-SPS). The rapid technological development makes social science students able to practice i-SPS through practicum methods. In addition, the existence of internet access can facilitate them to criticize phenomena through argumentation.. The aim of this study was analyzing the integrated science process skills (i-SPS) and argumentation of social science students. i-SPS were trained through demonstration methods and virtual experiment methods using pHET simulations, while argumentation were trained through debate activities involving pro-groups (pseudoscience view) and contra groups (scientific view). The research design was mixed method, the qualitative aspect is a content analyzing on i-SPS achievement of social science students who did rotation learning methods, while the quantitative aspect was the correlation test between i-SPS by pHET and argumentation. Mean score of  i-SPS by pHET was 83.46 and i-SPS by Demonstration was 55, while mean score of argumentation waas 77.88. The results of the nonparametric correlation test was r calculation was 0.175 smaller than r table 0.404 (sig 0.05 and N 24), so it was concluded that no correlation between i-SPS by pHET and argumentation. Majority of social science students about 75% have unequal category combinations of i-SPS by pHET and argumentation. Students’ i-SPS-PHET does not affect their argumentation. Several factors can influence the argumentation of social students, such as experience about phenomena, information disclosure in digital era , and the characteristics of debate involves pro and contra groups which expands knowledge.

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

It takes the ability to conceive at three different levels of representation, macroscopic, sub microscopic, and symbolic to comprehend acid-base material. Still, most students are unable to make the connection between the three levels of representation. As a result, instruction that helps students connect various representations in acid-base content is required. The PBL model is one appropriate learning paradigm that can be used. The purpose of this study is to determine whether PBL models and conventional models differ in their capacity to support numerous representations. A quantitative experiment using a quasi-experimental study design is the research methodology employed. A post-test-only control group design is used in this study. The samples of this study were XI MIPA 3 as a control group of 34 students and XI MIPA 4 as an experimental group of 33 students. Simple random sampling was used to get the research samples. A post-test consisting of multiple-choice questions was the instrument utilized. With a reliability score of 0,802 across 20 items, the empirical validation results indicate that all instruments are appropriate for use as research measures. methods for gathering data through tests. Data collection techniques in the form of tests. The data analysis technique in this study is descriptive and inferential statistics with hypothesis testing in the form of the Independent Sample t-Test. With a sig value of 0,000 < 0,05, the results demonstrated that there is a difference in the ability of multiple representations between those taught using the PBL model and those taught using the conventional model.
