Abstract

The aim of the research is to describe students' mathematical connection abilities in terms of self-efficacy. The objectives were achieved through descriptive research with a qualitative approach. The research subjects involved were 10 students of class AK 1 at SMKN 1 Cikarang Utara. The instruments for collecting data are mathematical connection test questions, self-efficacy questionnaires, and interview guides. The score of the test results is calculated and analyzed based on the level of achievement of the mathematical connection indicators. The percentage of questionnaire results was calculated based on self-efficacy indicators and analyzed based on categorization. Interview data is used to strengthen conclusions regarding whether there is a relationship between students' mathematical connection abilities and their self-efficacy. The results of data analysis show that the achievement of students' mathematical connection ability indicators is still relatively low, as shown by the achievement of the connection indicator with other scientific disciplines of only 31% and the connection indicator with daily life of only 0.69%. This low achievement is caused by the condition of students' self-efficacy which is categorized as poor at the strength level and not good at the magnitude and generality levels

Abstract

The low results of student geometry learning require a trial of the think-pair-share method as a replacement for conventional methods. This research aims to: (1) compare the level of effectiveness of applying the think-pair-share method with conventional learning in improving student geometry learning outcomes, and; (2) determine whether or not there is a significant effect from using the two methods. The method used is quasi-experimental with a nonequivalent pretest-posttest control group design involving an experimental group and a control group. Each group consisted of 23 class VII students selected non-randomly from the population. Data was taken using a geometry learning outcomes test instrument. Data were analyzed using the N-Gain Score test, the results of the calculations were converted into interpretation categories for N-Gain effectiveness to be concluded. Research findings: (1) the application of both methods was "ineffective", as shown by the calculation results of the average N-Gain score (%) for the experimental group of 38.112% and the control group of 30.636%, and; (2) based on the results of the hypothesis test, it was concluded that there was no significant influence from the application of the two methods on improving student geometry learning outcomes. The implication of this finding is that it is not recommended to apply the think-pair-share method if it is only focused on improving the geometry learning outcomes of class VII students, but it can still be applied for the purpose of developing students' collaboration skills

Abstract

This research aims to determine whether or not mathematical literacy skills influence students' problem-solving abilities. The research method used is quantitative research with a regression approach. The subjects were 64 class XI students, who were selected using cluster random sampling from a population of 133 students. Data was obtained using the Mathematical Literacy Ability Questionnaire and Mathematical Problem Solving Ability Test Instrument. Data were analyzed using appropriate test statistics, namely the Chi-Square and Simple Linearity Test as prerequisite tests. Hypothesis testing is carried out in stages: (1) Pearson's Product Moment Correlation analysis, (2) Correlation Significance Test, and (3) Coefficient of Determination Test. After the data analysis, it was concluded that mathematical literacy abilities (X) positively influenced mathematical problem-solving skills (Y). This is proven by the calculation results of Sig.=0.000 < Sig.α =0.05 and the coefficient of determination value of 0.906. This means that mathematical literacy skills strongly influence mathematical problem-solving abilities, and the effect is 90.6%. The regression equation Y = -53.813 + 0.8189X shows that for every additional unit of variable X, the Y value or students' mathematical problem-solving ability increases by 0.8189.

Abstract

This research is based on the results of observations of class X IIS regarding student's mathematical communication in online learning ethics via zoom. Initial findings indicate that mathematical communication skills have emerged but are not optimal. In general, the research objective is analyzing student’s online learning ethics via Zoom in mathematical communication. The method used is descriptive qualitative method to reveal facts. The data are collected through observation, interviews, documentation and triangulation/combination. This study involved three students from class X IIS and the teacher as a validator at Senior High School Bunda Kandung. The data analysis technique uses an interactive model through four stages, which are data collection, data reduction, data display, and drawing conclusions/ verification. The results showed that student's learning ethics via zoom on student's mathematical communication skills for subjects 1 and 2 were optimal because subjects 1 and 2 were able to communicate, express ideas, manage thoughts, analyze and evaluate mathematical thoughts. However, subject 3 has not been optimal in communicating their mathematical thoughts coherently and clearly. Subject 3 is unable to analyze his thoughts and unable to behave well with his friends.
