Abstract

This study aims to produce teaching materials to improve problem-solving skills that are feasible to use as a class XII physics learning media on sound wave material. In addition, it is also to find out the response of students to teaching materials developed in terms of meeting the standards of usability and quality. This research is R & D research with design according to Borg including: needs analysis, product planning and development, product development, product evaluation, and final products. The instructional materials developed have been implemented in 63 students of class XII SMAN 5 Semarang. Data collection is done by giving a validation sheet to the senior teacher. Data on students 'problem solving abilities were obtained from the results of the pretest and posttest while the students' performance was seen from the observation of practical activities in the laboratory. Students are also given a questionnaire to provide input on the teaching materials that have been developed. The results of the study indicate that the product of development is declared feasible based on expert judgment. Implementation of teaching materials in physics learning in sound wave material is able to improve problem solving skills and student performance.

Abstract

The existence of misconceptions could affect students? problem solving ability in physics subject. The source of misconceptions could be derived from the text books that used by the students, from the students itself, as well as from the teachers. One of the learning models that might reduce the misconceptions on the topic of light was worksheets-assisted by problem based learning model. The purpose of this study was to identify the misconceptions experienced by the students of SMP IT BinaAmal on the topic of light, to analize misconceptions on the topic of light, to identify the descriptions of the students? improvement on the concept of light, and to identify the worksheets-assisted problem based learning could develop the students? scientific attitudes. The research method used mixed methods research using sequential explanatory design with pre-test and post-test Control Group Design. The sample of this research was the IX grade students of Hafshoh bint Abu Bakar class, and the IX grade students of Zaenab bint Jahsyi at SMP IT BinaAmal Semarang. The instruments that used in this study were questions and observation sheets. Based on the calculation of problem-solving test, in the experimental class obtained a gain factor of 0.553 with medium criteria, while the control class produces a gain factor of 0.249 with low criteria. The initial t-test shows thitung (-1.55) <t table (1.68) that the experimental class is no better than the control class. The final t test shows thitung (2,481)> t table (1.68) that the experimental class is better than the control class after the LKS-assisted PBL learning model is used. A very strong relationship between conceptual mastery and the reduction of misconceptions. LKS-assisted PBL learning influenced the results of the decrease in student misconceptions from 55.1% to 19.5% in the experimental class and a decrease in misconception from 59.4% to 31.9% in the control class. Based on the results of cognitive tests, obtained a qualitative data analysis, misconception that occurred in SMP IT Bina Amal on the concept of light, among others: regular reflections and diffuse; shadow formation, shadow space and shadow properties, light propagation; light sources and human processes can see things; and the law of refraction. Based on the result of the research, it is found that the LKS-based problem-based learning model is effective to reduce light misconception.

Abstract

Research has been carried out to analyze learning based on the character and friendly attitude of students. The purpose of this study is how the character and self-interest of students in learning physics in a learning model. The research design used was quantitative research with survey research. The research sample was public high school and private high school in Semarang. The instrument used was a questionnaire using a google form. The results of this study were the lack of student character in learning, one of which was the student's curiosity in learning with a character proportion of 48%. Then, the proportion of students' self-confidence or self-confidence is still classified as low category. Students who lack confidence in their achievements and in doing assignments at school can affect learning models that are less precise and effective.

Abstract

This research aims to develop a STEM-based performance assessment instrument to analyze students' creativity. This research used the Research and Development method referring to the 4D model. The define stage was carried out by conducting preliminary studies which were then analyzed, starting from analysis of initial, student, concept, task and learning objectives. The design stage was an initial design in the form of Draft I. The development stage was carried out to produce draft II, draft III, and final products from performance assessment instruments. Draft II was obtained through the results of expert validation revisions. Draft III was the result of small-scale product trials. The Final Product was from the results of large-scale product trials. STEM-based performance assessment instruments used to analyze students' creativity were developed in the form of 1) Lesson Plan, 2) Student Worksheets, 3) Grid, 4) Performance Assessment Sheet, 5) Assessment Rubric, and 6) Assessment Guidelines. Expert Validation of STEM-based performance assessment instruments used to analyze students' creativity produced valid criteria that was worthy of trial. Based on the results of product trials, both small-scale and large-scale also showed reliable categories. The developed STEM-based performance assessment instrument is valid and reliable so that it can be used to analyze students' creativity. Based on this, it was known the profile of students' creativity in two Public High Schools of Brebes Regency.
