The comprehensive physics laboratory work with model - Based reasoning to improve 21st century competence

Abstract

There are five types of physical laboratory work, namely deductive, inductive, science process skills, technical skills, and problem-solving where those have different goals. Currently, the laboratory work was more dominant on deductive, which does not optimally accommodate the students' required competencies for the 21st century. Related to the issue, this research is important to find the best laboratory work with model-based reasoning by engaging laboratory work of deductive, problem solving and technical skills into comprehensive laboratory work. We explore model-based reasoning by undergraduate students and design a comprehensive laboratory work to the improvement of critical attitude and teamwork as a part of 21st-century competency. This study used a mixed method with a sequential exploratory design. Qualitative data were collected with theoretical studies. Quantitative data are collected with a scale scientific attitude. Increased critical attitude and teamwork are analyzed with n-gain. These research results were comprehensive laboratory work with reasoning components, such as theoretical guide, technical formulation, experimentation, problem description, problem analysis, repair and revision, and evaluation. The application of comprehensive laboratory work could improve critical attitude and teamwork with the high category. This study has succeeded in finding alternative concepts in laboratory work physics with reasoning based on models.
