<![CDATA[Abstract The ability to understand concepts is very important and becomes the basis for supporting the solving of mathematical problems. The connection between one concept and another concept and one topic with another topic is a characteristic of learning mathematics. The relationship requires that each student must have the ability to understand the concepts well, but it cannot be denied that the ability to understand mathematical concepts is still low, as happened to theLangke Rembong 4Junior High School students. Learning innovation needs to be done to achieve a good understanding of concepts. This study aims to compare the understanding ability of mathematical concepts of students who follow a guided inquiry learning model with students who take direct learning. The research design uses Posttest only control group design. The population is all eighth grade students of Langke Rembong 4 Junior High School, totalling230 students. Sampling is done by random sampling with equality test between classes.It is then obtained class VIII A as the experimental class and class VIII C as the control class. Data collection uses tests in the form of description questions. Data analysis uses t-test with normality test and homogeneity test for the assumptions. The results show that the students who follow the guided inquiry learning have higher understanding of mathematical concepts than those who are taught with direct learning model. Keywords: inquiry, understanding of mathematical concepts]]>

<![CDATA[This research is a research development that aims to produce mathematics teaching materials based on Lampungnese etnomatematics. The research method consists of (1) data collection; (2) the design of teaching materials; (3) development of teaching materials; (4) validation I of teaching materials; (5) revision I of the validation results; (6) validation II; (7) revision II; (8) product trials; (9) final revision and production of teaching materials. Sampling was conducted on grade IV students at SDN 3 Kemiling Permai. The results of the validation of teaching materials from Lampung mathematicians and cultural experts gave an average score of 3.86 which was categorized as good or feasible, while the validation of teaching materials by the mathematics teacher gave an average score of 3.95 which was categorized as good or decent. In small class trials obtained an average score of student response questionnaire of 3.72 which is categorized as good or feasible. Then a large class trial obtained an average score of student response questionnaire of 3.89 which was categorized as good or feasible. The conclusion of this study is the lampungnese etnomatematics-based mathematics teaching materials are categorized as good and suitable for use in learning mathematics in elementary schools.

<![CDATA[Abstract This study aims to determine the effect of the Model-Eliciting Activities (MEAs) approach towards the students’ mathematical communication skills. This research is a quasi-experimental study by the nonequivalent posttest-only control group design. This research population was the eighth-grade students in SMP Negeri 2 Sungai Penuh that consisted of seven groups. The sample in this study consisted of two groups, namely VIII C as an experimental group and VIII D as a control group selected by cluster random sampling technique. In the experimental group, the MEAs approach was done while the control group was done with conventional learning. The research instrument used to measure students’ mathematical communication skills was a subjective test. The data were analyzed using the independent t-test. The results of data analysis showed that there is an effect of MEAs approach towards the students’ mathematical communication skills. Keywords: Model-Eliciting Activities (MEAs) Approach, Mathematical Communication Skills]]>

<![CDATA[This research aims to determine the effect of initial ability and self confidence together on mathematical communication ability, the effect of initial ability on mathematical communication ability, and the effect of self confidence on mathematical communication ability. This study uses a survey method, with multiple regression analysis techniques. Samples were taken using a random sampling technique. The data processing carried out results in a multiple regression equation Y = -2.365 + 0.110 X1 + 0.283 X2, the coefficient of determination (R Square) = 0.22, FCount (0.787) smaller than FTable (3.126), and tCount smaller than tTable . The conclusion of this study is the initial ability and self confidence together do not have a significant effect on mathematical communication ability, the initial ability does not have a significant effect on mathematical communication ability, and self confidence has no significant effect on mathematical communication ability. This study needs to be studied further because only 22% of the value of mathematical communication ability can be explained by using the initial ability value and self confidence, while 78% must be explained by other causative factors. Keywords: Initial Ability, Self Confidence, Mathematical Communication Ability]]>

<![CDATA[Innovative learning models have an influence on student achievement. This study aims to determine whether the PBL learning model is more effective than the STAD learning model (learning model that has been applied in schools) on mathematics learning achievement, whether there is a difference in the effect of the AQ of climber, camper, and quitter category students on mathematics learning achievement, and whether there is the interaction between the learning model and students' AQ on mathematics learning achievement. This research is in the form of quantitative research. The sample was taken using a simple random sampling technique where the experimental class was taught using the PBL learning model and the control class was taught using the STAD learning model. The data collection technique used the Questionnaire method for AQ data and the test method for students' mathematics learning achievement data. The data technique used a two-way unequal cell analysis of variance test with a 2×3 matrix and a further test using the Scheffe test. The results of hypothesis testing with a significance level (α) = 5% indicate that there is a difference in the effect of the learning model on mathematics learning achievement (Fobs=19.97 and Fα=4.13), there are differences in the effect of each AQ category on mathematics learning achievement (Fobs=94.59 and Fα=3.28), and there is no interaction between the learning model and students' AQ on mathematics learning achievement (Fobs=2.39 and Fα=3.28).]]>

<![CDATA[The purpose of this study is to describe the interest in learning mathematics for fifth grade elementary school students on prime number material assisted by ICT learning media, namely Visual Basic Application (VBA) Excel. The research method uses qualitative descriptive research. The subjects of this study were 5th grade students of Madrasah Ibtidaiyah (MI) II Celak which consisted of 26 students. The instrument was given in the form of a questionnaire for students' interest in learning consisting of 20 statements, with 10 positive statements each and 10 negative statements from five indicators, 1). Feelings of pleasure, 2). Student interests, 3). Student involvement, 4). Diligent in studying and diligent in doing math tasks, 5). Diligent and disciplined in learning and having a study schedule. Based on the results of data analysis, it was found that learning mathematics using VBA media can increase student learning interest. This is shown by the percentage of each indicator of student interest in learning. The highest indicator is the feeling of pleasure and interest of students in learning mathematics, each getting 87.02% and 89.18% which shows that students' interest in learning mathematics is very high.]]>
