Tangible Evidence

Scientific reasoning ability is important to have for students to understand the concept of physics and have a good mathematical reasoning ability. The scientific reasoning ability itself is the ability of a person to use his or her reasoning in resolving a problem by coming up with facts or tangible evidence, so that the conclusion can be drawn. The research was conducted with a view to analyzing the scientific reasoning ability of high school students in Banyuwangi city on temperature and heat material. The study used a research instrument in the form of a multiple-choice scientific reasoning ability test based on LCTSR. This type of research is descriptive research. The results of this research include the percentage of test result scientific reasoning ability of students in Banyuwangi city in the proportional reasoning is 60.51%, in variable control of 58.17%, at a probability reasoning of 49.87%, on The hypothetical-deductive reasoning is 47.4%, on the reasoning correlation of 20.53%, and the reasoning on conservation is 37.22%. The largest percentage is proportional reasoning, while the smallest is a correlation reasoning. Then it can be said that high school students in Banyuwangi City have the best scientific reasoning ability on the proportional reasoning pattern and the ability of scientific reasoning which is lacking in the pattern of reasoning the correlation.

Essay Test

This study aims to describe the scientific reasoning level of students in urban and rural areas on heat and temperature topic. This current study involved 104 students from two schools in urban areas and three schools in rural areas. The instrument used was a six-item essay test. The result showed that the students' scientific reasoning score was still low. However, based on the Mann–Whitney test, the study found that there was a significant difference in scientific reasoning scores between students in urban and rural areas. Both students in urban and rural areas were indicated to have higher proportional reasoning when compared to the other kinds of scientific reasoning. In particular, students’ proportional reasoning in urban areas was higher than in rural areas. The result also showed that probabilistic reasoning and correlational reasoning of students in the rural area tended to be unstable compared to students in the urban area. The implication is that physics teachers in the rural area should make maximum use of the facilities in practicing student reasoning skills.

Experience Difficulty

There is a generally acknowledged need for students to be quantitatively literate in an increasingly quantitative world. This includes the ability to reason critically about data in context. We have noted that students experience difficulty with the application of certain mathematical and statistical concepts, which in turn impedes progress in the development of students’ critical reasoning ability. One such concept, which has the characteristics of a threshold concept, is that of proportional reasoning. The main focus of this article is a description of the development of a framework using an adapted phenomenographic approach that can be used to describe students’ experiences in the acquisition of the concept of comparing quantities in relative terms. The framework has also helped to make explicit the elements that constitute a full understanding of the requirements for the proportional comparison of quantities. Preliminary results from using the framework to analyse students’ responses to assessment questions showed that many students were challenged by proportional reasoning. When considering the notion of the liminal space that is occupied en route to a full understanding of a threshold concept, about half of the students in the study were at the preliminal stage of understanding the concept and very few were at the threshold.

Modelling instruction is systematic instructional activity for constructing and applying scientific knowledge in Physics lesson. The purpose of this research is to determine the effect of Modelling instruction with different reasoning abilities on understanding physical concepts by controlling students’ prior knowledge. This research used experimental method with 2x2 factorial design with two Modelling instruction classes and two conventional classes with a total of 176 students. The instrument used was reasoning ability test, prior knowledge test, and physics concept test. It used LCTSR (Lawson’s Classroom Test of Scientific Reasoning) instrument. Prior knowledge test instruments consisted of 25 problems to identify how deep the students understand the topic before they undergo the learning process and physics concept test consisted of 25 problems. Based on the statistical test using two factor Ancova, it proved that there was a significant difference in students’ ability to master the physics concept between using Modelling instruction learning model and using conventional learning model. The result showed that the Modelling instruction increasing conceptual understanding better than conventional learning. There are two important parts in the Modelling instruction that are model development and model deployment. This study also confirms that there are significant differences in understanding the concepts between students of high reasoning ability and low reasoning ability. Students with high reasoning abilities have a better understanding of concepts than students with low reasoning abilities.
