Princes Thesalonika — Fri, 24 Jan 2025 00:00:00 +0000

During the Covid-19 Pandemic Indonesia experienced a learning crisis. For this reason, the government needs a solution to help recover the learning crisis by implementing the Independent Curriculum in schools. This research aims to see that the PBL model can improve problem-solving and mathematical communication skills using a contextual approach. The research method used is an experimental method with a quasi-experimental type. The students of class VII junior high school with one variable system of linear equations. The test to see problem-solving and communication skills uses a pretest and posttest. The results were that the problem-solving ability pretest got a 28 and a communication score of 29. This has not yet reached completeness. After being given the treatment of students, the results of the post-test of problem-solving abilities get an average score of 75 while the post-test of communication skills is 78. The average score on problem-solving and communication abilities fulfills the KKTP which is 75. So it can be concluded that the PBL Model can improve problem-solving skills and mathematical communication using a contextual approach.

This study aims to describe the errors and factors that cause students to make mistakes in solving trigonometry problems. This research is a descriptive research with a quantitative-qualitative approach. The data collection techniques in this study were tests and interviews. Based on the results of the study, the errors made by students were∶ (1) fact errors (68.55%), namely students did not write and incorrectly write the symbol or notation of the symbols "α" and "°" in trigonometry material, (2) concept errors (30.65%), namely students could not and incorrectly determine trigonometric comparisons and students did not understand and apply the relationship between special angles and trigonometric comparison formulas, (3) operation errors (53.23%), namely students are unable to complete root form operations correctly and incorrectly enter the value of trigonometric comparisons (4) principle errors (70.16%), namely students are wrong in applying the Pythagorean formula and cannot apply the trigonometric comparison formula. The causes of errors made by students in solving trigonometry problems are∶ (1) remembering, in the form of students' lack of ability to remember material that has been learned from simple to difficult material, (2) understanding, in the form of students' lack of ability to understand the content of previously learned material, and (3) applying, in the form of lack of ability to describe material that has been learned in new situations and involves the use of rules or principles.

This research is based on an interview with a mathematics teacher of class X SMAN 1 Palangka Raya. Errors in solving the problems are caused by students having difficulty understanding and determining the formula used. At school, there has never been an identification of errors and causes of student errors in solving the quadratic function problems. The purpose of the research is to identify and describe the types of errors and the causes of students making mistakes in solving the quadratic function problems. This research is descriptive research with a qualitative approach. The research was conducted in the even semester of the 2023/2024 school year. The research subjects consisted of 42 students. Tests and interviews are data collection techniques used. After the test, three students were selected to be interviewed to find the causes of errors. The results concluded that the types of errors made by students in solving quadratic function problems are: (1) Conceptual errors, students forget to write signs in parentheses when describing the square, incorrectly determine the formula used, and lack of student understanding of the quadratic function material. (2) Procedural errors, students are not correct in the steps when solving the problem or the completion steps are incomplete. (3) Technical errors, students are wrong in calculating the value of mathematical operations and students' inaccuracy in mathematical operations. The causes of students making mistakes are: (1) Knowledge, because students forget, and also the lack of student knowledge of the quadratic function material. (2) Understanding, most students lack understanding and lack of understanding of the quadratic function material. (3) Application, students are not precise in their solution steps.

Chemistry learning at the high school level is often considered difficult due to the abstract nature of the material and the lack of interactive teaching materials that support students' learning styles. This study aims to develop and test the effectiveness of an Inquiry-Based Learning (IBL) e-Module on Hydrocarbons as an interactive teaching resource. The research method used is Research and Development (R&D) with the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. Data collection was conducted through student needs questionnaires and interviews with teachers at SMAN 3 Kota Tangerang, followed by validation by experts and a trial with students from class XI7. The results show that the developed e-Module has excellent quality based on expert validation and received positive feedback from students during the trial. Students found the module engaging, easy to understand, and effective in helping them grasp the concepts of hydrocarbons through the IBL steps. Therefore, this e-Module can serve as an innovative alternative in chemistry learning, particularly for the hydrocarbons topic, to create a more interactive and enjoyable learning experience.
