<![CDATA[The purpose of this study is to find out how the activities and roles of parents towards numeracy learning at home are reviewed based on parents with different types of jobs. The research method used is descriptive qualitative research. Data was collected using a questionnaire guideline which includes counting activities at home done with the mother, interview guidelines as clarifying material from the questionnaire which contains counting activities done with the mother and the media used. The results showed the role of (1) parents who work as entrepreneurs have played a good and compact role in providing facilities that support counting activities at home, (2) parents who work as self-employed are quite good at providing facilities for counting activities at home, this is because parents are less compact and less involved in the process of children learning to count at home, (3) while parents who work as teachers have played a very good role in providing facilities for counting activities at home, and always provide motivation. This shows that parents' awareness is an important point in teaching counting at home.]]>

<![CDATA[One of the factors that influences a person's level of success in the learning process is self-efficacy. Low self-efficacy and student learning outcomes in the learning process are the background for this research. In order for student self-efficacy and learning outcomes to increase, there needs to be a learning process that makes students learn meaningfully, one of which is the model discovery learning. The purpose of writing the article is to see whether there is an increase in student self-efficacy after implementing the discovery learning model and whether there are differences in learning outcomes between the application of the model discovery learning and student learning outcomes using the scientific approach. The method in this research uses experimental research methods with research instruments in the form of questionnaires given to students before and after the learning process using discovery learning models and learning outcomes tests. Based on the calculations, it was found that there is an increase in students' self-efficacy after applying the model discovery learning, with a value of 0.43 categorized as a "moderate" improvement. This indicates that the discovery learning model positively contributes to enhancing students' self-confidence. This means that there is an increase in student self-efficacy by implementing the model discovery learning. For student learning outcomes, the calculation results obtained are ????ℎ???????????????????? = 2.38 and ???????????????????????? = 1.67. This means that student learning outcomes by applying the model discovery learning are better than by applying learning using the scientific approach.]]>

<![CDATA[This research is based on the results of a preliminary study which identified students' learning barriers in algebraic multiplication and division material in elementary schools. Students do not fully understand the concept of algebraic multiplication and division due to learning obstacles related to limited didactic designs made by teachers. Learning obstacles experienced by students must be anticipated through a learning process that is able to overcome these problems. The researcher developed a didactic learning design using a Realistic Mathematics Education (PMR) approach. The aim of this research is to determine the learning obstacles experienced by students, develop didactical designs for algebraic multiplication and division, describe, test, and describe the designs that have been created. The research method used in this research is Didactical Design Research (DDR). This method consists of three stages, namely didactic situation analysis before learning in the form of Hypothetical Learning Trajectory (HLT) and Pedagogical Didactic Anticipation (ADP), metapedadidactic analysis and retrospective analysis. The data collection technique used is triangulation which combines observation, interviews and documentation. The design development process was carried out in class V with a total of 18 students, and the preliminary study stage was carried out in class IV at SDN 1 Sukamanah with a total of 22 students, and class IV at SDN Sukamulya with a total of 16 students. This research produces data regarding student barriers to multiplication and division material, didactical design in the form of teaching materials, student worksheets (LKPD), to minimize students' learning barriers to multiplication and division material in algebra.]]>

<![CDATA[This study aims to determine the effectiveness of the STAD cooperative learning model in terms of students' self-efficacy towards mathematics learning outcomes, particularly in the topics of Least Common Multiple (KPK) and Greatest Common Divisor (FPB), for fourth-grade students at SD Negeri Manyaran 02, divided into two learning groups: Class IV.A with 25 students and Class IV.B with 24 students. The research design employed in this study is quasi-experimental. Quasi-experimental research is conducted under conditions that do not allow for full control. Data collection utilized questionnaire and test techniques, followed by data analysis using a two-way ANOVA and further post hoc tests (multiple comparisons). Based on the tests, the test instrument was declared valid, with difficulty index reaching ???? < 0.30 for difficult criteria and ???? > 0.70 for easy criteria, as well as a reliability index of ????11 > 0.70. The study findings indicate that there is no significant effect of the STAD cooperative learning model on mathematics learning outcomes when viewed from the self-efficacy of fourth-grade students. However, the relationship between the STAD model and self-efficacy in mathematics learning outcomes shows positive results. Students with higher self-efficacy indices are proven to have better learning outcomes compared to those with lower self-efficacy levels.]]>

<![CDATA[The process of learning mathematics only focuses on understanding students but have not been able to develop their creative way of thinking. Students do not have the opportunity to explore answers or ways that are different from what the teacher teaches, so students cannot be creative in finding answers. The application of the creative problem solving learning model and concrete media in the form of nets of cubes and blocks is one solution to this problem. The purpose of this research is to find out: the difference in the average value of creative thinking skills after using the creative problem solving model and concrete media for fourth-grade students at SDN 1 Kaliombo. The experimental approach used in this research is the Pre-Experimental Design model in the form of a Pretest-Posttest Group Design. This study used fourth-grade students at SDN 1 Kaliombo as subjects, taking samples using total sampling or census. The research data was obtained from a statistical analysis of the t-test in the form of a Paired Sample t-Test. This study shows that: there is a difference in the average value before and after using the creative problem solving model and concrete media with a significance of 0.000 <0.025. Therefore, the CPS model assisted by concrete media can be said to have an effect on students' creative thinking abilities.]]>

<![CDATA[Junior high school of mathematics Olympiad is one of the routine activities every year in Indonesia. Analysis of the items on the Mathematical Olympiad test instrument has been carried out by several researchers using the concept of classical test theory. The theory has many weaknesses when compared to the concept Item Response theory (IRT). The purpose of this article is to describe the analysis of pre-Olympiad mathematics test instrument for junior high school students in Pacitan East Java based on the IRT. This analysis was carried out using a quantitative descriptive method. IRT-based item analysis was performed using R software with the package irtawsi. The results of the analysis with the package show that the instruments used fit to 2PL model. From the 15 items used, there were two items that did not fit, namely items 4 and 9. Furthermore, from the 13 test items that were fit, there were 3 items that did not meet the quality of the discriminant parameter used. These three items are 1, 6 and 13 items, these three items must be dropped because they can provide biased information when used to estimate students' math olympiad abilities. Based on this information it can be concluded that there are 10 test items that have quality that meets the qualification parameters of difficulty and discriminant with a standard error of 0.25. ]]>
