How does student learn mathematics through traditional food? (a hypothetical learning trajectory)

Luthfiana Tarida — 2023-10-25

This study aimed to design a hypothetical learning trajectory for a two-dimensional figure area (quadrilateral and triangle) using the geometric shape of traditional food, tempe mendoan as a learning context. This research was qualitative research with data collection methods using literature studies, interviews, and documentation. The subjects in this study were seventh-grade junior high school students in SMP IT Nurul Fikri Bogor. The results of this study are in the form of a hypothetical learning trajectory design in learning the two-dimensional figure area through exploration of Banyumas food tempe mendoan, students measure each side of the rectangle from the shape of tempe mendoan, students divide the rectangle into square units as many as the results of each measurement side, students counts the number of unit squares that cover the rectangular area, the student finds the formula for the area of a square and a rectangle. Next, students divide one rectangle into two right triangles of equal size, students find the formula for the area of a triangle. Students attach the triangles to the provided two-dimensional figure shapes, students record the number of right triangles needed to cover each shape and find these relationships so that students can find area formulas for other shapes such as parallelograms, trapezoids, and rhombuses.

The Effectiveness of the Liveworksheet Assisted Project Based Learning Model on Mathematical Literacy in View of Student Learning Motivation

The mathematical literacy of students at SMP Negeri 26 Semarang is not yet optimal. This research aims to determine learning mastery, average student mathematical literacy, the influence of learning motivation on mathematical literacy, and describe students' mathematical literacy in terms of learning motivation in class using a project based learning model assisted by live worksheets. This research used a mixed-method explanatory sequential design. The quantitative method in this research used a true experimental design with a posttest-only control group design involving two groups as an experimental group and a control group.The population of this study was class VIII of SMP Negeri 26 Semarang. The sample for this research was class VIII-G as the experimental class and class VIII-E as the control class taken using simple random sampling techniques. The subjects of this research consisted of 2 students in each category of high, medium and low learning motivation who were selected using purposive sampling technique. The results of this research show that: (1) students' mathematical literacy in Project Based Learning with Liveworksheet assistance has reached the actual completion limit; (2) the average mathematical literacy of students in Project Based Learning assisted by Liveworksheets is better than the average mathematical literacy of students in Problem Based Learning; (3) There is an influence of learning motivation on students' mathematical literacy with a percentage of 42.8%; (4) Subjects with high learning motivation have high mathematical literacy abilities because they tend to be able to fulfill the three indicators well. Subjects with moderate learning motivation have moderate mathematical literacy abilities, because there are still indicators that have not been met properly. Subjects with low learning motivation have low mathematical literacy abilities, because they do not fulfill the three indicators well.

Mathematical Representation Ability in Terms of Students’ Learning Independence in Project Based Learning Model Assisted by Google Sites

Inayah Wulandari — 2023-11-30

The purposes of this study were to analyze the quality of learning mathematics in the Project Based Learning model assisted by Google Sites on mathematical representation ability, to analyze the effect of learning independence on mathematical representation ability, and to describe the mathematical representation ability in terms of learning independence in the Project Based Learning model assisted by Google Sites. The research used mixed method with sequential explanatory design. The population in this study were all grade VIII students of SMP N 22 Semarang in the 2022/2023 academic year. The sample selected in this study consisted of class VIII E as the experimental class and class VIII F as the control class. Data collection techniques used in this study were tests, questionnaires, observations, and interviews. The results of the study showed that: (1) mathematics learning with Project Based Learning model assisted by Google Sites is qualified in developing students' mathematical representation ability; (2) there is a positive effect of learning independent on mathematical representation ability in Project Based Learning model assisted by Google Sites; (3) the description of the mathematical representation ability in terms of learning independence is divided into 3 categories, namely (a) students with high learning independence are able to fulfill all indicators of mathematical representation ability; (b) students with moderate learning independence are quite able to fulfill indicators of mathematical representation ability; and (c) students with low learning independence tend to be able to fulfill indicators of mathematical representation. However, it is necessary to pay attention to students' mathematical representation abilities, one of which is that students with low learning independence should be given guidance in processing information to be able to represent problems well to facilitate better problem solving.
