Profile of Guided Discovery Learning Implementation Assisted by Virtual Lab and Students’ Problem-Solving Skills on Gas Kinetic Theory

This research was conducted to obtain a guided discovery learning implementation profile with virtual lab assistance and problem-solving skills for high school students on gas kinetic theory. The type of research was descriptive preliminary research, without hypothesis testing. The research subjects consisted of 106 students in senior high school. This study used qualitative descriptive analysis from questionnaires and online tests. This study revealed that the level of students’ problem-solving skills was low. This case was proven by 102 students (27 male; 75 female) in the low category with a score range of 0 to 45, and four students in the moderate category with a score range of 46 to 75, while there were no students in the high category with a score range of 76 to 100. This research implies that there is a need for a guided discovery learning model with the help of a virtual lab to analyze the problem-solving skills of high school students, especially on gas kinetic theory.

The product development, which has been validated and revised, was then tested on 44 students of class XI public high school in Surabaya using the One Group Pretest-Posttest design. Based on the research data, it can be concluded that the PhET assisted inquiry worksheets on the supported gas kinetic theory teaching materials are declared valid in quality in training high school students' critical thinking skills with an increase in skills reaching 80%.

Application of Snowball Throwing Model to Improve Students’ Understanding of Concepts and Communication Skills in Gas Kinetic Theory

This research is based on the number of students who find it difficult to learn physics because of the lack of understanding of concepts and only memorization and still lack of communication skills of students. Based on this background, a study was conducted that aims to improve the understanding of students' concepts and communication skills by applying snowball throwing learning model on gas kinetic theory material. The method used in this study is experimental method, the population in this study is all students of XI IPA SMA IT Nurul Jannah and then selected with simple random sampling technique so that there are 23 students of grade XI IPA SMA IT Nurul Jannah. The result of the study is the application of snowball throwing model can improve the understanding of the concept with a pretest average of 25,6 and then increase by a posttest average of 57,4, with a large N-gain of 0,4 so that the medium category and t-test results of 7,65 are greater than the table t with a confidence level of 5%. The snowball throwing learning model can also improve students' communication skills, with an initial average of 45,41 and after the application of the model to 67,15, with a large N-gain of 0,4 so that the medium category, as well as the t-test results are 8,48 greater than the large, t-table that is 2,07. So, it can be concluded that the Learning Model of Snowball Throwing can improve the concept and communication skills understanding of student. For further research, it is recommended to utilize learning media to improve concept understanding by collaborating using snowball throwing learning models.

Hasil penelitian ini digunakan sebagai masukan bagi guru dan calon guru untuk memilih bahan ajar fisika yang berbasis multimodel pada topik teori kinetik gas.This research is motivated by the low learning outcomes that require teachers' efforts by holding variations in the learning process to improve the quality of students in learning. This research's general objective is to describe the feasibility of multimodel-based physics teaching materials on the topic of kinetic gas theory. The specific purpose of this study is to describe the validity, practicality and effectiveness of teaching materials. This type of research is research and development with ADDIE models. The research data were obtained through validation sheets and observation sheets to implement lesson plans and observation sheets for learning outcome tests. The results showed that: 1) the validity of categorized teaching materials was very good, namely the validity of the lesson plan obtained an average score of 3.61; the validity of student's worksheet obtained an average score of 3.51; the validity of teaching materials obtained an average score of 3.28; and learning achievement test validity obtained an average score of 3.72; 2) the practicality of teaching materials is categorized very well with an average implementation of RPP 1 meeting of 3.61; The 2nd meeting amounted to 3.68, and meeting 3 at 3.84; and 3) the effectiveness of teaching materials meets the effective criteria with an N-gain of 0.69 in the medium category. It was concluded that multimodel-based physics teaching materials on the topic of a kinetic gas theory are feasible in the learning process because they meet the declared valid, practical, and effective categories. This study's results are used as input for teachers and prospective teachers to select multimodel-based physics teaching materials on the topic of gas kinetic theory.

PENGEMBANGAN E-MODUL FISIKA BERBASIS PENDEKATAN SAINTIFIK PADA MATERI TEORI KINETIK GAS

This research is motivated by the difficulties experienced by students in understanding gas kinetic theory material and the limitations of multimedia teaching materials possessed by teachers. The purpose of this study is to develop a physics-based e-module based on the Scientific Approach using 3D Professional Pageflipp on the gas kinetic theory material and to determine students' perceptions of the e-modules developed.
