The Effectiveness of Problem Based Learning Aided by Gamification Teaching Materials on Students' Mathematical Problem Solving Ability
Get PDFThe low mathematical problem solving ability of junior high school students in Pringsewu, Lampung, Indonesia is because students understand the explanations given by the teacher and are less active during the learning process. The study was conducted to determine the differences in problem solving of students who follow the learning process using the PBL model using gamification teaching materials. The research uses quantitative methods with a quasi-experimental design type of research. The population used is junior high school students in Pringsewu, Lampung, Indonesia. The research sample used cluster random sampling technique. The data analysis used was one-way ANOVA analysis of variance with a significance level of 5% using SPSS which obtained a value of sig. <0.05 so H_0 is rejected, this indicates that there is an effect. After conducting a further test in the form of a Scheffe test, it can be concluded that there is an effect of the PBL learning model using gamification teaching materials on students' mathematical problem solving abilities.

Data collection techniques used are questionnaires and student learning outcomes tests. From the results of the data analysis, the value of sig. (2-tailed) = 0.005 on the results of the visual learning style test with high emotional intelligence was obtained. Meanwhile, the visual style learning outcome test with moderate emotional intelligence obtained a value of sig. (2-tailed) = 0.000 and the visual learning style with emotional intelligence obtained a value of sig. (2-tailed) = 0.001. It can be said that there is an influence on visual learning style using Problem Based Learning on significant learning outcomes of the emotional intelligence of class XI students of SMA Negeri 1 Menganti in 2021/2022. Keywords: problem based learning, visual learning style, emotional intelligence, mathematics learning outcomes. DOI: http://dx.doi.org/10.23960/jpmipa/v23i2.pp392-39
Mathematical Representation of High School Students in Understanding the Concept of Arithmetic Sequences and Series
Get PDFThis study aims to describe the mathematical representation ability of class XI MA Sumber Payung students in understanding the concepts of arithmetic sequences and series. This type of research is descriptive qualitative research. The results obtained by students with high math skills in understanding the concepts of arithmetic sequences and series are in the form of representations of mathematical equations/expressions, where students can create mathematical equations or models from other representations given, solve problems involving mathematical expressions and representations of words/written texts. Students can write down what is known and asked in a data or information, so that in answering questions using words or written text. Likewise for students with low mathematical abilities, representation in understanding the concept of arithmetic sequences and series is in the form of representations of mathematical equations/expressions and representations of words/text. Keywords: Representation, understanding arithmetic concepts, sequences and series. DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp78-8
Abilities and Difficulties of Ninth-Grade Students in Solving Geometry Transformation Problems
Get PDFGeometry is one of the challenging subjects for students. This study aimed to determine the ability of students to solve geometric transformation problems, the difficulties they experienced, and the causes. This research employed a mixed method with a sequential explanatory design. Eight Year 9 students were the subjects of this study. Data were collected through tests and interviews. The data were analyzed quantitatively, followed by qualitative analysis involving reducing data, presenting data, and concluding. The results indicated that the student's ability to solve geometric transformation problems was moderate. Students found it difficult to solve geometric transformation problems. The student's difficulties included determining the translation when a starting point and an image point were given and determining the image of a point/curve by a transformation. Students had not fully mastered the schemes in the geometric transformation, were not proficient in using formulas, and were not precise in their calculations.Keywords: students’ difficulty, transformation, translation, rotation, dilatation.DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1724-173
High School Students’ Ability with Translation Among Mathematical Representations in Solving the HOTS-Based Problems
Get PDFTranslation is considered as a step in transforming the information contained from the source representation to the destination representation. In the process of students doing mathematical translation there are four stages of activity, Unpacking the Source, Preliminary Coordination, Constructing the Target, and Determining Equivalence. This study aims to analyze the activities carried out by students in translating representations from graphic to symbolic, table to symbolic, and verbal to symbolic based on HOTS. This research was conducted at SMA Lamongan Regency with three research students in class XI who had learned about the concept of quadratic functions. The instruments used were translation questions and interview guidelines. The applied data analysis focused on four stages of translation activity which were then grouped according to (high, medium, and low categories). The results showed that the translation of verbal representations into symbolic ones was the most difficult for students to complete.Keywords: mathematical translation, representation, HOTS.DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1887-189
