Abstract

The development of science, technology, and society requires humans to have skills beyond literacy and numeracy that are needed to survive. Scientific literacy is the focus of learning in the 21st century. Currently, the scientific literacy index of students in Indonesia is still low. Chemistry is a part of science. Chemical literacy is the ability of students to identify, analyze, and process chemical concepts to solve everyday problems and communicate scientifically the chemical phenomena that occur around them. Colloidal material in chemistry learning has some abstract concepts close to everyday life. So the purpose of this study was to determine the chemical literacy ability of students on colloidal material in North Aceh and Lhokseumawe. The subjects of this study were 217 students of class XII, in SMA North Aceh and Lhokseumawe. The instrument used in this study is a chemical literacy question in the form of a description consisting of 8 PISA standard chemical literacy questions. The result of this research is that the highest student answers are on the literacy scale with nominal criteria, while the lowest is multidimensional criteria. According to the distribution of chemical literacy scores in the Aceh region, the highest was in the medium-grade category with 142 students, and the lowest was in the high-grade category with 14 students.

Abstract

As the spearhead of successful learning in the classroom, a prospective teacher must have qualified abilities and skills, teacher competence and teaching quality need to be ensured. One of the ways to measure the competence of prospective chemistry teachers is by using authentic assessments. This assessment can be done digitally through an authentic digital-based assessment with a project-based learning model. The model, research design and instrument development carried out in this study is an adaptation of the test preparation procedure with the following instrument preparation steps: (1) planning the test, (2) trying out the test, (3) establishing test validity, (4) establishing test reliability, (5) interpreting the score. In this study, there were three parameters studied, namely (1) Analysis of the needs of prospective teachers at school. (2) Preparation of authentic assessment instruments that have been developed based on validators, (3) Analysis of observing, inferring and predicting skills. Analysis of school needs is the basis for the preparation of authentic assessment instruments and models that are compiled. The results of the learning instruments that have been compiled and have been developed have excellent quality criteria with an average per aspect of 0.875 and are declared valid based on the assessment of material experts, media experts and peer reviewers. The validated instrument is then implemented where the Implementation Analysis on prospective teachers in the observing aspect gets a score of 3,374 including in the excellent category, as for inferring, it gets a score of 3,217 including in the good category, in the predicting aspect it gets a score of 3,553 including the excellent category, so that the average teacher candidate gets a score of 3,392 including the excellent category. Meanwhile, the affective instrument of students got a score of 3.22 on the persistence aspect and 3.16 on the attention aspect, both of which were in the good category. So that the average affective aspect of the participants got a score of 3.19 and was included in the good category

Abstract

VR (VR) is a technology created with the aim of creating a three-dimensional (3DVR) simulated environment where users can observe and interact with the contents of that environment. This research aims to develop and assess the quality of a 3D-VR-Based Virtual Lab learning media. The development of learning media in this research uses the ADDIE development model. However, in this research, it is limited only to the development stage, namely validation by media experts and feasibility testing. Based on the validation results from each media validator, covering three aspects: audiovisual, software engineering, and instructional design, good results were obtained. Therefore, 3D-VR media developed is declared valid and feasible to be tested with learners.

Abstract

This research is to produce a suitable digital assessment tool for high school students' in chemical literacy with validity, reliability, levels of difficulty and discrimination power. The research metodology is Research and Development (R&D) using the Oriondo and Dallo-Antonio model. The research stages include planning the test instrument, testing, determining empirical validity, determining reliability, and interpreting test scores. In the planning (instrument creation), where the validation score estimates by experts in content, language, construction, and media are above 0.8, indicating that the test instrument is considered suitable for further testing to estimate validity, reliability, difficulty levels, and discrimination power. Out of the 25 developed questions, 24 fit the Rasch model. The reliability of Instrument Part I is 0.67, and Part II is 0.65, falling into the "sufficient" category. The questions exhibit varied difficulty levels, ranging from very easy to very difficult, with a standard deviation (SD) of 0.21 for Part I and 0.14 for Part II. The separation achieved by Instrument Part I is into 4 ability groups, while Instrument Part II separates into 2 ability groups. The distractors for multiple-choice questions fall into the "good" and "very good" categories, fulfilling their intended function effectively.
