Abstract

Human actions that exploit natural resources and the environment without limits have caused global conditions to become increasingly concerning. A lack of environmental awareness is also evident in students who neglect to care for and protect the environment, such as by littering. This issue requires serious attention and can be addressed by fostering an environmentally caring character through an integrated ethnoscience approach incorporating Islamic values. Ethnoscience-based learning, integrated with Islamic values, can be facilitated through an electronic student worksheet. This worksheet was designed to help students connect cultural elements with scientific concepts and the teachings of the Quran. Correspondingly, this study developed an electronic student worksheet using a 4D model, encompassing three stages: Define, Design, and Develop. Data from the product development and assessment process were analyzed quantitatively and descriptively. The final product featured character education based on Islamic values. It received an “excellent” rating from material and media experts, while teachers and students responded positively to the media. Overall, this electronic worksheet could potentially improve environmental awareness and instill Islamic values in students.

Abstract

This research aims to determine chemistry teachers' perceptions of ethnoscience-based learning approaches and the characteristics of the Keris Yogyakarta, as well as to examine its potential for high school chemistry education. This qualitative study involves ten high school chemistry teachers in Yogyakarta. Data collection techniques included questionnaires, interviews, and analysis of the high school chemistry curriculum. The research instruments used were survey sheets and interview guidelines. The data were analyzed using qualitative methods of Miles and Huberman. The results show that chemistry teachers have a positive perception of the ethnoscience approach. The Keris can serve  as a thematic element to introduce Yogyakarta culture in chemistry learning. Relevant chemical topics include elemental chemistry and redox reactions. The chemical elements or compounds involved in making the Keris include iron, steel, nickel, arsenic, citric acid, and ascorbic acid. Ethnoscience learning about the Keris provides students with knowledge about applying chemical concepts in its manufacture, integrating local knowledge and culture, and helping students understand chemical concepts more easily and engagingly. Additionally, ethnoscience learning about the Keris can increase students' appreciation and concern for Indonesia's cultural heritage.

Abstract

This study aimed to develop and validate the Three-Tier Chemical Equilibrium Multiple-Choice Test–HOTS (TTCEMCT–HOTS) instrument. The method employed in this study was Research and Development (RD) based on Brookhart’s (2010) indicators of higher-order thinking skills. The development procedure began with a preliminary study, followed by product draft planning and product development. These stages were succeeded by an empirical analysis of the TTCEMCT–HOTS to determine the test instrument’s validity, reliability, difficulty level, and discriminating power. The TTCEMCT–HOTS instrument was implemented with Class XI students of SMAN 4 in South Tangerang City. The results of the study were as follows: (1) the developed TTCEMCT–HOTS instrument met the criteria of 32 valid questions, with a reliability coefficient of 0.82 in the “very high” category, a “moderate” difficulty level, and “good” discriminating power; (2) 46.42% of students could solve HOTS questions, while 53.58% could not; (3) the TTCEMCT–HOTS instrument received a positive response from 80.6% of participants, placing it in the “good” category. This study is expected to provide an alternative method for measuring students' higher-order thinking skills using a three-tier test instrument integrated with HOTS indicators.

Abstract

Low student learning outcomes are a significant issue in high school colloid chemistry learning. Correspondingly, this research aimed to determine the effectiveness of scientific literacy-based student worksheets (LKPD) in colloid chemistry learning. A quasi-experimental approach, specifically the pretest-posttest control group design, was employed in this study. The experimental class, XI IPA-2, consisted of 15 students, while the control class, XI IPA-1, also included 15 students, with total sampling techniques used to select the sample. Test instruments were developed to collect student learning outcome data through pretest and posttest techniques. The effectiveness of student worksheets was analyzed using the N-gain test, independent sample t-test, and effect size tests. The N-gain results exhibited an average score of 0.7319, which was a high category for the experimental class, while the control class obtained a score of 0.5308, which was categorized as moderate. The independent sample t-test results indicated a 2-taliled significance score of 0.002 ( 0.05), demonstrating a significant difference between the learning outcomes of the experimental and control classes. Based on these findings, it can be concluded that scientific literacy-based student worksheets effectively improved student learning outcomes in colloid chemistry learning at the senior high school level.
