GHANAIAN STUDENT NURSES’ ATTITUDES TOWARDS MATHEMATICS
No full textThis 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
REALISTIC MATHEMATIC EDUCATION ON HIGHER-ORDER THINKING SKILL MATHEMATICS OF STUDENTS
No full textThe literature on the effect of the Realistic Mathematics Education (RME) approach on high-order thinking skills (HOTS) students is massive. There is a diversity of research results. So a systematic and comprehensive review is needed to justify and describe its effect, which includes problem-solving, critical, creative, and reasoning abilities. This research used a systematic literature review (SLR) technique to search the Semantic Scholar, ERIC, Google Scholar database, and direct URLs from 2013 to 2022, yielding 49 studies that matched the inclusion criteria. Every paper was recorded and then categorized for analysis based on the title, education level, year of publication, sample size, and kind of HOTS. The findings indicated that RME positively impacted students' HOTS when learning activities were applied with student-centered, contextual problems, and the teacher was the facilitator. Working together in small groups allowed students to carry out individual exploration activities, reconstruct concepts from their own experiences, and connect these concepts to the mathematical ideas studied. RME thus becomes appropriate for use in achieving learning's aims and urgency, particularly in raising students' mathematical HOTS. The study's findings also offer information on the trends and heterogeneity of research into applying RME on mathematical HOTS in Indonesia. It is thus anticipated that it will serve as a recommendation and a focus for further study

STUDENTS' EPISTEMOLOGICAL BELIEFS IN SOLVING GEOMETRY TRANSLATION PROBLEMS
No full textThe 2018 PISA results show that Indonesian students' numeracy and literacy skills are poor. Epistemological beliefs, beliefs in mathematical knowledge, are one of the factors contributing to poor student literacy skills. This study analyzes epistemological beliefs in solving translation problems of Year 9 students in one of the junior high schools in Manipa Islands, Indonesia. This research employed a descriptive a qualitative approach. The subjects in this study were students who tend to meet the indicators of epistemological beliefs. Data collection techniques were observation, tests, interviews, and documentation. The results showed that students' epistemological beliefs in completing the translation met the requirements. First is being able to solve mathematical problems by taking time, where students needed time to solve the problem. This is because students are not sure that they can solve them. Second, students can solve problems that cannot be solved with simple, step-by-step procedures, where students solve problems using their rules/settlement procedures. The third is understanding essential concepts in mathematics, where students understand and work on translation problems using mathematical concepts well. Fourth, word problems are essential in mathematics, with word problems, students can improve critical thinking skill. Finally, efforts can improve mathematical abilities, where students can try to solve problems to improve their math skills. Efforts include reviewing the lesson and increasing practice questions
