Abstract

Teaching aids in the world of education is a medium that mediates to help clarifying concepts in learning mathematics. This study aims to determine the efect of the use of toy car props on students’ interest in learning mathematics, especially in comparison material. This research was conducted at SMPN I Bola VII class semester 2 of the 2019/2020 scholl year. This type of research is quantitative by using a quasi-experimental methods. The population of this study were 192 studentsof class VII SMPN I Bola with a sample 0f 23 students in the experimental class and 23 from the control class. The sampling technique used is class random technique. The instrument used in this study was a questionnaire of interest in learning. Before carrying out a hypothesis test it is necessary to do a prerequisite test that is a test for normality and homogeneit. The normality test  obtained significant values in the experimental class and control were 0,136 and 0,620, because the value obtained has a significance level 0f >0,05, it can be stated that the data is normally distributed. For the homogeneity test, the results obtained a significant value of 0,001 at a sisnificant level of 0,05, so it can be said that the data is homogeneous. After the data is normally distributed and homogeneous, it is continued with hypothesis testing. Hypothesis testing used the independent sample t-test obtained value of  t-count > t-table where t-count = 6,49 while t-table = 2,01 which means that the use of toy props has an effect on the interest in learning mathematics in class VII SMPN I Bola where students’interest in learning mathematics increases. Thus the teacher can use toy props related to the material and can be used in matematics learning so that students’ interest in learning mathematics increases.

Abstract

Vocational High School is a formal institution that creates more independent, creative, innovative, skilled, and responsible students in solving a problem. Graduates from vocational education are expected to be more competent in solving problems in the world of work. Students are also required to be more active in solving a problem. The research objective was to determine student activity and analyze mathematical problem-solving abilities in implementing mathematics learning using the Problem Based Learning model. The method used is to use a qualitative design. In this method, student activity is measure using the observation sheet, and the problem-solving ability test is carried out by following the steps of Polya's theory. The results showed that the overall student activity reached the excellent category. The general average problem-solving ability obtained an ideal classification, with the movement and moderate mathematical problem-solving ability of students achieving a reasonable variety and positively impacting all vocational students.

Abstract

This study analyzes students' mistakes in doing math problems on function limit material. This research was conducted at SMK Santo Thomas Maumere in semester 2 of the 2021/2022 academic year. This type of research is qualitative research. The subjects of the study were 3 students drawn from 26 students of class XII Nursing Assistants. The results of this study show that the types of mistakes made by students are fact, conceptual, principle, and procedural errors based on the classification of fundamental errors of mathematical objects. The factual error made by students is that students are mistaken in writing down the left limit and proper limit symbols. The misconception is that students do not understand the rules of the limit of a function. The principal error made by students is mistaken in describing a process. Finally, the procedural mistake made by the student is a mistake in writing. The factors that cause students to make mistakes in solving the function limit problem are that students do not know the left limit and proper limit symbols, students do not understand the concept of function limits, and prerequisite knowledge related to function limits owned by students is still minimal, students are not careful in solving function limit questions, and students still feel embarrassed if they ask teachers or colleagues regarding limit material that has not been understood

Abstract

This study aims to assess the mathematics learning outcomes of third-grade students at MIS Muhammadiyah Darussalam Waioti, Sikka (a private elementary school) on the topic of length units using the "smart ladder" media. This research follows a Classroom Action Research (CAR) approach, employing both qualitative and quantitative methods. It comprises two cycles, each consisting of four stages: planning, implementation, observation, and reflection. The subjects of this study are third-grade students. Data collection methods include tests and observation. Research instruments consist of an observation sheet for assessing student engagement and a test to measure learning outcomes. The findings reveal that mathematics learning using the smart ladder media showed improvement from Cycle I to Cycle II, with the learning outcome mastery level reaching 18% in Cycle I and student engagement observed at 44%. In Cycle II, the mastery level increased to 94%, with student engagement reaching 93%. These results suggest that the use of the smart ladder media for teaching length units effectively enhances the learning outcomes of third-grade students at this school.
