The Profile of Students’ Physics Problem Solving Ability in Optical Instruments

Abstract

This research aims to analyze the profile of students’ problem-solving ability in problems of optical instruments. This survey research involved 65 students class XI of MAN 3 Yogyakarta. The research instrument was in the form of 3 problem-solving questions in the form of a description. The results showed the percentage of students in the expert category was still relatively low at 30,7% and the students in the novice category were quite high at 69,3% so that students’ overall physics problem-solving abilities were relatively low. In this research, some student difficulties were still found, one of which was in determining the focus of the right lens for patients with eye disorders to use glasses and determine magnification when using a magnifying glass. Efforts to implement innovative learning are needed to improve problem-solving abilities in overcoming students’ physics problems.

Physics Learning with E-Book Using Problem Based Learning (PBL) Model to Improve Image Representation Ability of High School Students on Optical Material

“…Students' ability to understand images, and understand the relationship between variables in the picture affected learning outcomes. Students with good image representation ability, has a good learning outcome, because the representation serves as a tool to help solve problems in physics [26] [12] and make it easier to understand and explain certain phenomena [10][27] [28].…”

“…Fisher [9] states that the use of free body images can improve the ability to formulate equations in object motion. Students who have low problem solving skills tend to solve problems by entering or replacing values into equations without interpreting their meanings, so the solutions given are not appropriate [10]. Development of the ability to represent this image can be done at every opportunity in learning, such as the selection of learning resource media that support the presentation of image representation.…”

“…These concepts are needed in an explanation to understand certain phenomena and it is not enough if presented in the form of static images only. For example, the process of shadow's formation when looking at objects on optical material [10]. The process is not enough if illustrated through a static image.…”

Pengaruh Model Pembelajaran Problem Posing Tipe Pre Solution Terhadap Hasil Belajar Siswa Pada Materi Gelombang Bunyi Kelas Xi Sma

“…Untuk mengatasi permasalahan yang ada maka salah satu upaya adalah dengan pemberian model pembelajaran yang dapat menunjang pembelajaran fisika dan arahan kepada siswa agar mendapatkan hasil belajar yang baik. Salah satu model pembelajaran yang banyak diimplementasikan pada pembelajaran fisika adalah pembelajaran berbasis masalah [5][6][7][8][9][10][11][12][13][14][15][16][17].…”

The Development of Diagnostic Test Instrument for Verbal Representation Ability in High School Physics Learning

“…Learning physics at the high school and higher education levels emphasize problem-solving. Students are required to be able to solve the problem being studied [2], [3]. Therefore, some research in the field of physics education is designed to improve problem-solving.…”
