Abstract

Constraints found in science learning in junior high schools lead to low mastery of scientific concepts and communication skills. Therefore, this study aims to describe the early stages of analysis related to urgency as the basis for product development in the form of e-learning moodle in guided inquiry learning to improve mastery of scientific concepts and communication skills on substance pressure material and its application to everyday life. The method used was descriptive research using literature studies, curriculum analysis, needs analysis questionnaires, open interviews with science teachers, and student ability surveys using question instruments. The research subjects comprised 81 students and two junior high school science teachers. Based on the analysis results, it is known that students want a new learning atmosphere that involves several learning media and practicum-based learning. But the reality of learning still uses traditional methods and a single learning resource, namely textbooks. The development of learning media in the form of moodle e-learning with the guided inquiry learning model is expected to assist teachers in facilitating a new, fun learning atmosphere and involving practicum activities to improve students' mastery of concepts and scientific communication skills

Abstract

Abstract: This research aims to develop instrument test visualization skills on direct current electric circuits. The research method used is the development of a 4D model consisting of defining, designing, developing, and disseminating. The participants in this research consisted of 33 high school students in West Java who were randomly selected. The first analysis is an analysis of the results of expert validation using CVR, which is considered valid. The second analysis is the Rasch analysis, which obtained raw variance data with special interpretation and declared the questions valid. The third stage is the analysis of the parameters of the items included in the interpretation of very appropriate and appropriate. The fourth stage of the reliability analysis used Rasch analysis, which showed that overall visualization skills items were reliable with a Cronbach Alpha of 0.71. But the consistency of the answers from the respondents is weak. Students visualization skills need to be improved through models, methods, and visual media that support visualization skills.       Keywords visualization skills, direct current electrical circuits, 4D model, Rasch analysis. Abstrak Penelitian ini bertujuan untuk mengembangkan instrument test visualization skills pada rangkaian listrik arus searah. Metode penelitian yang digunakan yakni pengembangan model 4D yang terdiri dari defining, designing, developing, dan disseminating. Partisipan dalam penelitian ini terdiri dari 33 siswa SMA di salah satu SMA Negeri di Jawa Barat yang dipilih secara acak. Analisis pertama adalah analisis hasil validasi ahli menggunakan CVR yang termasuk valid. Analisis kedua adalah analisis Rasch didapatkan raw varian data dengan interpretasi istimewa dan soal dinyatakan valid. Tahap Ketiga adalah analisis parameter butir soal termasuk dalam interpretasi “sangat sesuai” dan “sesuai”. Tahap keempat analisis reliabilitas menggunakan analisis Rasch yang menunjukan secara keseluruhan item visualization skills reliabel dengan Cronbrach Alpha sebesar 0,71. Namun konsistensi jawaban dari responden lemah. Visualization Skills siswa perlu ditingkatkan melalui model, metode, dan media visual yang mendukung keterampilan visualisasi.  Kata kunci keterampilan visualisasi, rangkaian listrik arus searah, model 4D, analisis Rasch  DOI: http://dx.doi.org/10.23960/jpmipa/v24i1.pp84-97
