Abstract

The numeracy ability of students in Indonesia is in a low category based on PISA results from 2000 to 2018. So, efforts are needed to strengthen numeracy skills through the development of ethnoscience-based numeracy test instruments. The purpose of this study was to analyze the characteristics of the ethnoscience-based numeracy test instrument using the Rasch model.  The subjects of this study were students of SMPN Arun and SMPS Sukma Bangsa, Lhokseumawe City, totaling 123 students. The number of questions to be analyzed in the test is 68 items. Analysis using Winsteps software. The results of the analysis showed that the ethnoscience-based numeration instrument in this study was declared reliable. 59 of the 68 items were said to be valid, with details of 32 valid items eligible to be used and 27 valid items needing to be revised for improvement before being used. This instrument can be used to measure subjects who have ethnoscience-based numeracy skills in the low, medium, and high categories, so to examine ethnoscience-based numeracy skills students can use this instrument.

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

Penelitian ini merupakan penelitian kualitatif deskriptif yang bertujuan mengetahui self efficacy atau tingkat kepercayaan diri mahasiswa peserta program PMM 2. Subjek dalam penelitian ini berjumlah 121 mahasiswa yang mengikuti program PMM 2 di seluruh Indonesia dengan rincian sebanyak 56 universitas asal dan 20 universitas penerima. Teknik yang digunakan dalam pengambilan data adalah survey menggunakan angket self efficafy yang disusun berdasarkan indikator Bandura. Data yang dikumpulkan kemudian dikategorikan dalam tiga klasifikasi, yaitu rendah, sedang dan tinggi. Hasil penelitian menunjukkan bahwa mayoritas mahasiswa peserta PMM 2 masuk dalam kategori sedang. Sebanyak 79,34% mahasiswa peserta program PMM 2 memiliki self efficacy kategori sedang. Sedangkan sisanya sebanyak 9,09% memiliki self efficacy ketegori tinggi dan 11,57% masuk kategori rendah.

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.
