The level of students’ understanding is influenced by teaching methods and student learning styles. The aim of this article is to implement an active learning model based on experiential learning by considering learning styles for mechanical engineering vocational students. This study was performed in a state vocational school of a regency in Central Java. Case studies are carried out in the Basic Engineering Mechanical Design subjects in vocational high schools. Mastery of the basic concepts of machine design is a basic competency supporting knowledge to study and explore the field of mechanical engineering. Student learning style preferences were measured using a Index of Learning Style (ILS) by Felder-Solomon.

The goal of this research was to find of 2nd-year college students’ argumentation performance in the science class, including the way they prepare themselves in arguing, how the argumentation performance has changed over and how they engage in argumentation practice as a part of scientific communication. Scientific Reading-based Inquiry (SRbI) was applied in order to develop students’ scientific argumentation. This classroom research was held in one of the science education department in Central Java, Indonesia. Data were collected and analyzed from various sources: students’ argumentation performance while presenting their ideas, their writing quality, structured interview, and lecturer notes. Performance assessment was used to qualitative declare students’ understanding of argumentation practices. The results indicated that students’ ability to argue in the context of scientific argumentation has varied and changed as they experienced in citing proper literature and used the information as a part of evidence and explanation. It recommends that proper instruction can bolster students in developing stronger comprehension of scientific knowledge and arguments.","PeriodicalId":246056,"journal":{"name":"THE 2ND INTERNATIONAL CONFERENCE ON SCIENCE, MATHEMATICS, ENVIRONMENT, AND EDUCATION","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134570998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
