Abstract

This study aims to analyze the understanding of first and second-year Chemistry Education students about the global carbon cycle. The design of this research is descriptive research, using the Global Carbon Cycle Diagnostic Instrument (GCCDI) instrument with 11 questions. The subjects of this study were first- and second-year undergraduate students of Chemistry Education at Bengkulu University, with a total of 15 students in each group. The students' understanding was analyzed qualitatively through the survey method. The data were analyzed and categorized into four groups: understand, misconception, doubt, and do not understand for the GCCDI. The students' understanding was categorized into simple, medium, and complex schemes for the survey method. The results indicated that, for first- and second-year students, respectively, the category of understanding comprised 53.31% and 58% of responses, the misconception category accounted for 22.38% and 27.24%, the doubtful category represented 4.8% and 6.65%, and the category of "does not understand" comprised 19% and 7.85%. The survey method was employed to analyze the responses of first- and second-year students on three schemes: simple (40% and 20%), medium (26.6% and 33.3%), and complex (33.3% and 46.6%). The low level of understanding of the carbon cycle indicates the need for more effective learning approaches, such as in-depth curriculum development, the use of interactive learning methods, and the integration of technology to improve students' understanding of the carbon cycle concept in the broader context of science.

This study aims to identify subconcepts that experience misconceptions, the percentage of students who experience misconceptions, and the causes of misconceptions that occur in students. The research method used is the quantitative descriptive method. The sample of this study was students of grade X MIPA at SMA N 1 Jetis, which was taken based on purposive sampling techniques. The research instrument used was the Four Tier Multiple Choice (4TMC) diagnostic test instrument. The pattern of answers, reasons, and confidence rating from the Four Tier Multiple Choice (4TMC) test results are then processed and analyzed to obtain significant misconception data from students. The results of the research obtained, namely, there were misconceptions in stoichiometric material, especially in the subconcepts of Avogadro's Hypothesis, Proust's Law (Law of Fixed Comparison), Dalton's Law (Law of Multiple Comparison), Ar and Mr, the percentage of grade X students at SMA Negeri 1 Jetis on stoichiometric material who experienced misconceptions of 25.35% which was classified as a low category, as well as the causes of misconceptions experienced by grade X students at SMA Negeri 1 Jetis on the material This stoichiometry comes from teachers, learners, and books. Misconceptions originating from teachers are related to learning methods, techniques, and delivery. Misconceptions originating from students are caused by wrong conceptions of learners, dependent algorithmic phenomena, learners' abilities, and students' interests, which need to be improved. At the same time, the misconception from the book is the existence of inappropriate concepts in the student's notebook. Identifying these misconceptions is expected to be the first step to remediate student misconceptions on stoichiometric material and prevent prolonged misconceptions.

Abstract

The main supporting component of a comprehensive learning implementation, scientifically prepared according to the chemical context, is developing a chemistry lesson plan. Scientific explanations in chemistry learning often involve causal mechanistic explanations of chemical phenomena, which provide a paradigm for understanding chemical concepts. This research aims to describe how prospective chemistry teachers use scientific explanations to develop CER framework in chemistry lesson plans that align with STEM learning. A descriptive qualitative research design was used. The authors conducted this research on 20 prospective chemistry teachers. This research used the document review, observation, CER framework assessment, and interviews. Prospective chemistry teachers can theoretically and practically prepare chemistry learning plans. The study reveals that prospective chemistry teachers struggle to offer scientific explanations for the concepts they explain through CER framework. Their responses to the CER framework assessment reveal numerous unconnected scientific explanations.  One cannot combine evidence and reasoning claims into a systematic unity to explain a chemical phenomenon.

Abstract

Gravimetry is a simple and fast method used to determine the weight percentage of alkaloid content in natural samples when analyzing compound content. Gravimetry is a basic knowledge and skills in analytical chemistry. A student-centered learning approach is needed to acquire integrated chemical laboratory knowledge and skills. Integrated learning outcomes between knowledge and skills can be achieved, one of which is through project-based learning (PjBL). One of the things we report in this article is the development of a practical module based on PjBL. This article reported the research and development (RnD) of a project-based practical module on gravimetric analysis using the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) stages to obtain a valid and reliable practical module. The module's validation was analyzed using content validity with the FGD technique through the assessment of five experts. Validity data analysis used Aiken's and Cronbach's alpha for reliability. This article also reports the results of observations of the PjBL practicum of gravimetric alkaloid analysis by 18 students regarding the clarity of the practicum objectives, content, instructions, and ease of the module in guiding the practicum in the Laboratory. By using the ADDIE development steps, we produced a PjBL practicum module with the validity of the Aiken analysis results showing an index of 0.92, indicating that the module developed was valid, had a reliability of 0.78, and had a practicality percentage of 89.77%. The developed PjBL teaching module has also increased students' motivation and basic chemistry laboratory skills when conducting gravimetric analysis practicum.
