Abstract
<p>This study aims to determine the profile of scientific reasoning ability of junior high school students in Jambi. The type of this research is descriptive quantitative, while the research design using survey type cross-sectional design. The population in this study were junior high school students in Jambi City with a total of 25,789 students. The sampling technique used is cluster sampling. The sample used in this study is 1146 students from 15 schools with different accreditation levels. Techniques of data collection of this study are using the problem of reasoning abilities from lawson's classroom test of scientific reasoning (CTSR) in 2000. The results showed that 100% of the sample is concrete. With the ability of Conservation of matter and volume as the most ability owned by students with the percentage of 16.1% and the lowest ability is the ability of Proportional reasoning with a percentage of 3.0%. This shows that students have not been able to use their reasoning for abstract things. In general, no reasoning ability that has a percentage of 50% indicates that students' reasoning ability in junior high school is still very low and fundamental. </p><p><em> </em></p><strong>Keywords: </strong> Profile, scientific reasoning, junior high school, Jambi city<p> </p>
Highlights
Physics is a branch of Science a scientific study of matter and energy and how they interact with each other
The average result of scientific reasoning ability of junior high school students in Jambi City can be seen as follows
Based on table 4, the highest scientific reasoning ability of junior high students is the conservation of matter and volume that is only owned by 16.1% of all students, it states that this capability only has 16 out of every 100 samples, and the most scientific reasoning ability of low is proportional reasoning that is owned only 3.0% of all students, which means that the scientific reasoning ability of junior high school students in Jambi is still low
Summary
Physics is a branch of Science a scientific study of matter and energy and how they interact with each other. Through the study of physics, students are expected to develop reasoning abilities (reasoning) in the thought of inductive and deductive analysis using physics concepts and principles to explain natural events and problem-solving both qualitatively and quantitatively. By knowing how the characteristics of learners a teacher will be able to design an effective and interesting learning. One of the characteristics needed in the design of learning is the stage of development of learners. This developmental stage of the learner can be explained through the ability of scientific reasoning. By knowing the profile of this scientific reasoning ability, the teacher will be easy to determine the right approach and teaching method (Nehru and Syarkowi, 2017)
