Abstract

In essence, this research is a development research with the aim of producing quality learning tools. To achieve that, the development of the model used in this study is the development of the 4-D model proposed by Thiagarajan, into three stages namely the Define stage, the Design stage and the Develop stage. The population of this research is the students of class X-1 and X-2 SMA Swasta Kartika I-4 Pematang siantar. The learning tools developed are lesson plans and LKPD. The instruments used consisted of validation of learning tools, validation sheets for students’ mathematical critical thinking skills, teacher respone questionnaire validation sheets, student response questionnaires validation sheets, student activity observation validation sheets,  teacher  response questionnaires, student response questionnaires, and student activity observations. The results show that the learning tools developed with the scientific approach: (1) are in the very valid category; (2) has met the criteria of being very practical and effective; (3) there’s an increase in students’ mathematical critical thinking skills from trial I to trial II by 14.69%. Researchers suggest that learning with a scientific approach becomes an alternative of teachers in improving students’ mathematical critical thinking skills.

Abstract

The purpose of this study was to determine the quality of ethnomathematics-oriented student worksheets (LKPD) based on students' mathematical representation abilities produced in this study in terms of valid, practical, and effective criteria that have been set. This type of research is research and development (R&D), namely the development of student worksheets based on ethnomathematics orientated from students' mathematical representation abilities. R&D, namely the development of worksheets developed based on the Plomp model which consists of the initial investigation phase (prelimenary investigation), design (design), realization/construction (realization/construction), test, evaluation and revision (test, evaluation, and revision). The test subjects in this study were class VII-4 students of SMP Negeri 1 Tanjungbalai Asahan. Based on the results of the trials carried out, data obtained from the validation results of experts with an average of 93% is in the very valid category, because 81% - 100% so that the LKPD is said to be very valid. Furthermore, student worksheets were assessed by students with an average response of 93% in the very practical category, and the teacher's response with an average response of 90% in the very practical category. So based on the results of the students' mathematical representation ability test they completed classically with an average of 94% in the very effective category.

Abstract

This study aims to analyze students' cognitive load in learning mathematics on trigonometry material. This type of research is a qualitative descriptive research. This research was conducted at SMK Negeri 1 Tanjung Tiram involving 30 students of class X-TEI. Data collection techniques in this analysis used purposive sampling, and data collection techniques were carried out by descriptive tests to measure students' intrinsic cognitive load, questionnaires to measure students' extraneous cognitive load, and interviews to measure students' germane cognitive load. The data analysis technique used in this study is to calculate the results of the data obtained from each instrument in depth. The results of this study indicate that the intrinsic cognitive load of class X-TEI students at SMK Negeri 1 Tanjung Tiram has a fairly high intrinsic cognitive load with an average value of 57.1 in the fairly good category, the extraneous cognitive load experienced by students is 62.53%. with the quite effective category, and the germane cognitive load experienced by students, namely the lack of students' understanding of some trigonometry material, one of the contributing factors is because the teacher's way of explaining is too fast and also a lack of learning references. Thus it can be concluded that the cognitive load of students in learning mathematics in trigonometry material is still quite high, so that this research can be an evaluation from various parties and can be used as study material for other researchers in analyzing students' cognitive load in learning mathematics, especially in trigonometry material.

Abstract

The purpose of this study was to determine the effectiveness of the Blended Learning Learning Model in terms of Students' Critical Thinking Ability in the Three-Variable Linear Equation System Material in Class X SMA Air Joman Private Regional Academic Year 2021/2022. This type of research is descriptive qualitative research. The subjects in this study were all students of class X MIPA 1 consisting of 24 students. The data collection instruments used included test questions in the form of 5 questions which referred to indicators of students' critical thinking skills including the ability to generalize, the ability to identify, the ability to formulate problems into mathematical models, the ability to deduce using principles and the ability to provide further explanations. The data analysis technique used in this study was assessing the results of students' answers and determining the percentage of students' critical thinking skills scores seen from student answer sheets. It can be explained that there are 17 students who get a complete score, and 7 students get an incomplete score. Mastery in critical thinking skills is a benchmark for determining student success in solving critical thinking skills test questions. The effectiveness of Blended Learning in terms of students' critical thinking skills in the matter of a three-variable linear equation system in class X SMA Air Joman Regional Private School for the 2021/2022 academic year is 71% with the criteria being quite effective

Abstract

This study aimed at describing the mistakes of stidents in solving problem in the material of the material of the three-variable linear equation system in terms of students communication skill. This type of research is a qualitative approach with descrits research methodology thatvaimed at determining the description of the error analysis and the differences in the errors made by students in solving math problem. The subjects of this study were 25 students in class X of SMA Sepakat Sei Balai in the academic year of 2019/202020. The test instrument used in this study was in the form ofb6 test questions that referred to indicators of communication skill including (1) Explaining ideas, situation and mathematical relationship verbally or in writing, with real objects, pictures, graphics, and algebra. (2) Stating everyday events in mathematical symbols. (3) Reading with written mathematics comprehension or presentation. Based on the results of the study, it was concluded that the students made mistakes in answering the questions.
