This study aims to determine the effect of RME on the spatial abilities of Year 8 students concerning cuboids and cubes. Geometry problems often experienced by junior high school students, such as difficulty knowing the difference between cuboids and cubes, difficulties showing elements of cuboids and cubes, and difficulty imagining cuboids and cubes in the case of rotation. The teacher should not underestimate it because it will impact the next level of learning. Besides, spatial abilities are closely related to other mathematical concepts. One alternative is using RME. This research employed the quasi-experimental method, and samples were selected using purposive sampling techniques. The two classes were selected as samples in this study: the experimental and the control classes. Before conducting the main analysis test, the pre-test score students were tested with the t-test. The initial conclusion was that there was no difference in the spatial ability of the experimental class and the control class. The main analytic test in the post-test was done using U-test. The post-test results show that the average score of the experimental class is higher than the control class; RME positively influences students' spatial abilities.

This study aimed to examine the attitudes of Ghanaian student nurses towards mathematics. A sample of 301 undergraduate nursing students at a university in Ghana, selected through census sampling techniques from the first to the third-year students, participated in the study. Data was collected using a 5-point Likert scale questionnaire and analyzed using descriptive and inferential statistics. The study revealed that the students’ attitudes towards mathematics are determined by the value they attach to mathematics and their interest in mathematics. At α=0.01, Spearman's rho correlation coefficient of rs = 0.619 was significant. This indicates that the more value the student nurses attach to mathematics learning, the more interest they will likely have in learning the subject. The coefficient of determination (R2=38%), indicates that the students’ value for mathematics accounts for 38% of the variability in their interest in mathematics.

Teachers need to understand students' early mathematical abilities before continuing learning on the next topic to retain the knowledge. This study aims to produce appropriate and reliable instruments for quality research related to early mathematical abilities. This research implemented R&D. The subjects were 113 sixth-grade students of the elementary school in Karawang. The instrument used was a test to measure early mathematical ability. Validity and reliability tests indicated that the five initial mathematical ability test items were considered valid, with r count > r table and p-value <0.05. The Cronbach's Alpha value was 0.875 (above 0.8 or high reliability). Thus, the five items of the early mathematical ability instrument on the volume of cubes and rectangular prisms can be used for further research to measure the same variables accurately. The results are not significantly different for the same subject even though the time and place are different.

This study aimed to determine the effect of learning media on student achievement in mathematics. The learning media used include learning using Zoom Meeting, Google Classroom, and face-to-face in class. The research method used was an experiment with a quantitative approach. The samples were 30 Year 9 students divided into three different treatments in learning: learning using Zoom Meeting, learning using Google Classroom, and face-to-face learning in class. The instrument used was a description of the essay questions used to measure student achievement. Data were analyzed using one-way ANOVA and Tukey's - HSD test. The results showed a significant or different effect between the use of learning media on student achievement (Fcount = 3.665 > Ftable = 3.35) of α= 5%. Furthermore, further tests were carried out using the Tukey's - HSD test to examine which learning media had a different effect. Further test results showed that learning using Google Classroom with face-to-face learning in the class had a different effect on students' mathematics learning achievement. Meanwhile, student achievement between Zoom Meeting and face-to-face learning and Zoom meeting and Google Classroom was not significantly different. The average student learning achievement in face-to-face learning was greater than those using Google Classroom.

Set is an important topic to be mastered by students because it influences the development of mathematics in daily life. However, many students still have difficulty learning the topic. Therefore, it is necessary to design a learning trajectory using the appropriate approach, context, and media. This research resulted in the learning development using Sedekah Laut context to create meaningful learning and increase students' understanding of sets. The method used in this study was design research proposed by Gravemeijer & Cobb with three stages: preliminary design, experimental design (pilot experiments and teaching experiments), and retrospective analysis. However, this article only presented the results from the Preliminary design stage. The participants involved in this study were 7th-grade students of SMP Negeri 6 Semarang. The resulting hypothetical learning trajectory consists of a series of learning processes: observing context videos to find the concepts of sets, non-sets, empty sets, universal sets, and Venn diagrams; explaining the properties of the set; defining set operations; and solving problems related to sets.
