Abstract

Meta-analysis is an activity that involves identifying, evaluating, and interpreting relevant research to systematically combine the results of existing studies. This research aims to analyze central tendency, variation, and errors in studies. This research uses four theses related to the development of Android-based learning media on colloid material. This research employs a quantitative meta-analysis method with the following steps: 1) Searching for sources and identifying thesis documents, 2) Expert assessment by media experts, material experts, and students, analyzing N and I values, 3) Calculating effect size and standard error, 4) Creating a forest plot for the effect size and standard error values. The results of the study are as follows: In the development studies of Android-based learning media on colloid material, media experts, material experts, and students have different percentage levels due to differences in location, research subjects, and media used. The assessment by media and material experts most suitable for Android-based colloid learning, reviewed from effect size and forest plot, is in study or research NA-22. In the material expert assessment, study RS-19 is the most suitable evaluation to obtain student responses for the development of Android-based learning media on colloid material.

Abstract

Education in Indonesia aims to produce excellent students capable of contributing to the nation's progress. However, many schools still struggle to achieve an ideal level of learning, one of the contributing factors being the learning difficulties experienced by students. Chemistry is often perceived as a difficult subject due to its abstract and complex concepts. Determining reaction enthalpy changes in thermochemistry is one of the subtopics that students find challenging, leading to learning difficulties at the high school level. This issue is crucial to understand because chemistry concepts are interconnected, and difficulties in one area can affect the understanding of subsequent concepts. Hence, a study on students' difficulties in understanding the concept of determining reaction enthalpy changes is essential. This research was conducted on 125 Grade XI-MIPA students from two high schools in Palangka Raya. Data on students’ difficulties were collected using a diagnostic essay test instrument on the ability to determine reaction enthalpy changes (TKPPER), consisting of four questions. The aim of this research was to describe the difficulties experienced by Grade XI-MIPA students in the 2022/2023 academic year in understanding the concept of determining reaction enthalpy changes using diagnostic essay tests. The results showed that students experienced difficulties in understanding the concept of determining reaction enthalpy changes, with an average difficulty percentage of 37.44%. Several conceptual indicators focused on in the study exhibited varying levels of difficulty: Determining reaction enthalpy changes based on Hess's Law (65.67%), with students facing the following difficulties: (a) Assuming it is sufficient to sum the enthalpy change values (∆H) of three reactions provided in the question without considering the thermochemical equations of these reactions. (b) Believing that the value and sign of ∆H remain the same even when the thermochemical equation is reversed or the roles of reactants and products are switched. Determining reaction enthalpy changes based on bond energy (43.90%), with students experiencing the following issues: (a) Assuming that some compounds involved in the reactants and products are treated as single compounds in the chemical reaction. (b) Simply summing the bond energy values of each compound in the products and reactants without considering the number of bonds in each compound. Determining reaction enthalpy changes based on standard enthalpy change data (20.38%), with students facing the following challenges: (a) Assuming that the reactants in a chemical reaction are the products and vice versa. (b) Believing that it is sufficient to sum the bond energy values of each compound involved without accounting for the number of compounds (stoichiometric coefficients) in the reaction. Determining reaction enthalpy changes based on calorimeter experiment data (19.82%), where students struggled with identifying the values of the components in the formula, specifically determining the mass of water (m), specific heat capacity of water (c), and temperature change (∆T).

Abstract

Chemical bonding material has abstract concepts. This research was conducted because there are still many student difficulties in chemical bonding material, so a method of organizing data is needed to describe and summarize student difficulties. This research used systematic review method. The sample in this study used three theses about the difficulties of high school students in understanding the concept of chemical bonds. The data of this research is in the form of student difficulties from the answer patterns and instruments used in each thesis. Instrument analysis in the form of Basic Competencies (KD) and Operational Verbs (KKO) from each thesis while student difficulties are analyzed by comparing student answer patterns. The results of the research on student difficulties in understanding the concept of chemical bonding, namely (1) difficulties in the electron configuration sub-concept are that students cannot determine the stability of elements correctly. Students write the electron configuration out of order and write the atomic number according to the element, (2) the difficulty in the valence electron sub-concept is that students assume the determination of valence electrons based on the number of electrons in the last sub-shell, (3) the difficulty in the ionic bond sub-concept is the lack of student understanding of the properties of metallic and non-metallic elements, (4) the difficulty in the Lewis structure sub-concept is that students assume that by describing just one point it has become one Lewis bond electron pair. Students assume that all atoms that make up the molecule are considered elements, (5) the difficulty in the covalent bond sub-concept is that students assume that the coordination covalent bond is a bond that occurs due to the use of electrons together, and (6) the difficulty in the metal bond sub-concept is that students assume that it is formed between metal and non-metal elements.

Abstract

This study aims to analyze the need for the development of differentiated learning-based e-Worksheet (e-LKPD) on the acid-base concept at SMA Negeri 2 Palangka Raya. Differentiated learning allows teachers to present materials and assessments tailored to students' varying abilities and learning styles. The research method used is qualitative descriptive, with data collection techniques including questionnaires, interviews, and observations involving teachers and students. The results show that teachers need a comprehensive, interactive, and flexible e-LKPD with adjustable content and exercises of varying difficulty levels. Students desire a visually appealing e-LKPD that is easily accessible across multiple devices and includes interactive features and instant feedback. In conclusion, the development of a differentiated learning-based e-LKPD is essential for improving the effectiveness of teaching the acid-base concept, supporting individual differences among students, and facilitating active engagement in learning.

Abstract

This study aims to evaluate the effectiveness of practical learning activities in the chemistry laboratory of Palangka Raya University on increasing the understanding of SMAN 2 Kahayan Tengah students regarding the safety and use of chemistry laboratory equipment. This study uses a pre-experimental design with a one-group pretest-posttest approach. Grade XI students who participated in practical learning activities included the delivery of laboratory safety materials, introduction to laboratory tools and instruments, and demonstrations of simple chemical experiments. Student comprehension data was collected through pretest and posttest, then analyzed using the Wilcoxon signed-rank test and N-gain calculation. The results showed a significant increase (p < 0.05) between pretest scores (mean = 62.00) and posttest (mean = 80.33), with an average N-gain value of 0.48 which was included in the medium category. The conclusion of this study is that practical learning activities in the chemistry laboratory of the University of Palangka Raya are effective in improving the understanding of SMAN 2 Kahayan Tengah students regarding the safety and use of chemistry laboratory equipment.
