The Analysis of Students Scientific Reasoning Ability in Solving the Modified Lawson Classroom Test of Scientific Reasoning (MLCTSR) Problems by Applying the Levels of Inquiry

Abstract

This study aims to determine the students' achievement in answering modified lawson classroom test of scientific reasoning (MLCTSR) questions in overall science teaching and by every aspect of scientific reasoning abilities. There are six aspects related to the scientific reasoning abilities that were measured; they are conservatorial reasoning, proportional reasoning, controlling variables, combinatorial reasoning, probabilistic reasoning, correlational reasoning. The research is also conducted to see the development of scientific reasoning by using levels of inquiry models. The students reasoning ability was measured using the Modified Lawson Classroom Test of Scientific Reasoning (MLCTSR). MLCTSR is a test developed based on the test of scientific reasoning of Lawson's Classroom Test of Scientific Reasoning (LCTSR) in 2000 which amounted to 12 multiple-choice questions. The research method chosen in this study is descriptive quantitative research methods. The research design used is One Group Pretest-Posttest Design. The population of this study is the entire junior high students class VII the academic year 2014/2015 in one junior high school in Bandung. The samples in this study are one of class VII, which is class VII C. The sampling method used in this research is purposive sampling. The results showed that there is an increase in quantitative scientific reasoning although its value is not big.

Problem Solving Heuristic to Develop Scientific Reasoning

“…Scientific reasoning ability can be developed with implementation of heuristic methods on discovery learning models. The results of this study is like other studies that the level of reasoning can be improved by learning activities with testing hypothesis or theory procedures (Lawson, 2004;Erlina et al, 2016;Wu et al, 2016;Novia & Riandi , 2017). Scientific reasoning patterns of experimental group show Figure 5.…”

Analyzing of Student’s Mathematical Reasoning Ability in Solving Mathematical Problem Based on Higher Order Thinking Skill (HOTS)

“…The results of this study are in line with [13], [14] statement that reasoning and proofing abilities are very important for building students' understanding of mathematical concepts. Leithner in [8] mentions that reasoning is the foundation of mathematics, unfortunately, students at all grade levels find it difficult in mathematical reasoning problem including undergraduate students of mathematical majors.…”

Development of the Interactive Multimedia Software “Inquiry Play-Room” as an Electronic Learning Resource for Rotation and Equilibrium Topic

“…The steps of the model include 1) observation, 2) manipulation, 3) generalization, 4) verification, and 5) application [27]. This learning-based inquiry is positively correlated with the ability of scientific reasoning, in which students are required to follow a process that is systematic and purposeful, beginning with identifying a problem, proposing a hypothesis, identifying variables, conducting an experiment, analyzing data, and drawing valid conclusions [28]. The model characteristics indicate that the students must conduct experiments.…”
