Abstract

This study aims to find out how much percentage of each student's learning difficulties at number operations in solving the story problems in class VIII of Tanjung Palas State Middle School 2. This research was conducted in the odd semester of 2018/2019.This type of research is quantitative. The sampling technique used by Nonprobability Sampling with the type of Purposive Sampling sampling technique is the determination of samples with certain considerations, where the number of students sampled is 26 students. The results showed that the student learning difficulties with the highest percentage average score for students of Tanjung Palas 2 Public Middle School were operating indicators of 38.72% with a high category, followed by a principle of 43.59%, with a high category of concepts with categories 48.46% high, and 62.05% facts with a low category.

Abstract

This research aims to determine the influence of cooperative learning models (TAPPS and conventional type) on mathematical critical thinking ability, the influence of high and low mathematical disposition on mathematical critical thinking abilities, and the influence of interactions between learning models (TAPPS and conventional type) with students’ mathematical disposition on mathematical critical thinking skills in eighth grader of SMP Negeri 7 Tarakan. This research was carried out in the odd semester of 2018/2019 school year in SMP Negeri 7 Tarakan. The type of research used in this study is a quasi-experimental with a 2×2 factorial design. The population in this study were all eighth grade students of SMP Negeri 7 Tarakan. Sampling is done by simple random sampling. The sample in this study is class VIII-1 as a control class and VIII-3 as an experimental class. Data collection is done by using mathematical critical thinking ability test and mathematical disposition questionnaire. Data analysis techniques using descriptive and inferential analysis. Descriptive analysis includes mean and standard deviation. Inferential analysis uses two-way variance analysis. Based on the results of the analysis with a significant level of 5%, it can be concluded that the learning model (TAPPS and conventional) influenced the ability of  mathematical critical thinking with p-value 0.046, high and low mathematical disposition affect the ability of mathematical critical thinking with a p-value of 0.000, and there is no influence of interaction between learning models with mathematical disposition of mathematical critical thinking skills in class VIII SMP 7 Tarakan with p-value 0.503.

Abstract

The development model used is the Borg and Gall model of Sugiyono modification. In the Borg and Gall model, the Sugiyono modification consists of 10 stages, namely Potential and Problems, Data Collection, Product Design, Design Validation, Design Revision, Product Testing, Product Revision, Usage Testing, Product Revision and Mass Production. The media testing phase is done through 2 stages, namely the assessment of experts and user response. In the assessment of experts validated by material experts, media experts and linguists. While the user response was tested by 30 students and 2 mathematics teachers. The results of analysis shows that the kosami product developed based on validation by material experts obtained a feasible category with a percentage of 79.68%, media experts obtained the category of Very Eligible with a percentage of 92.72% and linguists obtained the Very Eligible category with a percentage of 83.33%.While the result of research in the field by the response of teacher user obtained a percentage of 75% with a Very Practical category, responses of student users obtained by 87,33% with a Very Eligible category, and responses of student users obtained by 90,67% with a Very Practical category . Because it has fulfilled the feasible and practical requirements of a Kosami learning media consisting of aspects of material feasibility, media feasibility, feasibility of language use, and practicality of user response, the kosami can be used as a feasible and practical learning media for students of clas VII SMP Negeri 7 Tarakan on  Number Material.

Abstract

This study aims to identify the level of students' mathematical arithmetic skills in solving problems in the summing material based on counting on in class II of SD Negeri 018 Tarakan. The method used is a quantitative approach to the type of descriptive explanation. The results of the study were obtained from the students' numeracy ability test results based on the mathematics numeracy ability category of students in the high and medium categories. The problems used to identify the ability to count scheme are three problems, namely problems related to counting on, counting all, then counting on and counting all. The results of students' math skills based on the counting on scheme were obtained through interviews with 25 research subjects. Problem 1 was solved by students with a counting scheme of 10 students (40%), Problem 2 was solved by students with a counting scheme of 1 student (4%). Problem 3 is solved by students with a counting on scheme of 2 students (8%).
