Abstract
This research aims to analyze the practicality and effectiveness student worksheet based on multiple representation to improve conceptual understanding and problem-solving ability, especially in magnetic material. The research method using quasi experiment with pretest-posttest control group design. The sampling technique used purposive sampling technique, class XII student high school in Bandar Lampung. The instruments are feasibility student worksheet of observation sheet, student responses to the student worksheet, student activity sheets, and conceptual understanding test and problem-solving ability test. Data were analyzed using descriptive analysis by percentage, N-gain analysis, and independent t-test. The results showed student worksheet based on multiple representation: 1) practical, which is indicated by a) the average score student worksheet enforceability in any learning activity that is 87.31 with very high criteria and b) the positive response of students (83.75%) against student worksheet. 2) effective, which is indicated by a) the student's activity during the study included in the active category, and b) there are significant differences in conceptual understanding and problem-solving ability between the experiment class and control class. Conceptual understanding and problem-solving ability are taught using student worksheet based on multiple representation the experimental class better than the control class.
Highlights
Data assessment results practicality shown by feasibility student worksheet and students 'responses to student worksheet form of qualitative data, while data on the results of the assessment of effectiveness demonstrated by the observation of students' activity in the form of qualitative data and test conceptual understanding and problem-solving abilities of physics students in the form of quantitative data which can be seen from the students’ pretest and posttest scores
The test products in this study were taken one class taught by using student worksheet based multiple representation and other classes of the same level as the comparison taught by using conventional student worksheet
The Practicality of student worksheet based multiple representation measured through feasibility student worksheet in learning and students' responses to student worksheet
Summary
Every human being needs education until whenever and wherever located. The rapid development of education certainly pose challenges, especially the selection of appropriate teaching materials and use of technology in education including challenges in physics. Science deals with how to find out about a natural phenomenon systematically. Scientists built the concepts and theories that often uses abstract symbols so that it becomes difficult to understand. This makes most of the students are less fond a physics lesson at school. Not a few problems in physics on abstract and complex material is very difficult to solve because many involve complex mathematics [1]. In learning physics students are required to be able to build their own knowledge and actively participate in the learning process
