<![CDATA[Negative perceptions of mathematics cause students to be lazy, uninterested and even refuse to study mathematics, resulting in low student achievement. The aim of this research is to describe the steps for learning pair check with the help of question cards to improve learning achievement in circle material. This research is classroom action research. The research subjects were 30 class VIII students at SMPN 2 Turen. Data collection uses observation, documentation and test techniques. The research instruments used observation. Sheets, field notes, photo and video documents, and test. The research results show that pair check learning begins by assigning students to study reading material individually, then solve problems in groups of 4 students. Next, give question cards to be completed in small groups (2 students). In small groups, students take turns playing the role of partner and coach in solving the questions card. Discussion of question answers is carried out classically through presentation activities. Student learning achievement using the pair check model assisted by question cards has increased. In cycle 1, 70% of students had completed their studies. The results of this research are expected to provide alternative stages and learning media that can improve student learning achievement.]]>

<![CDATA[This study aims to compare the effectiveness of learning using Contextual Teaching and Learning (CTL) and the Missouri Mathematics Project (MMP) in terms of students' mathematics learning outcomes. The research method employed was an experiment with a pretest-posttest non-equivalent comparison-group design. The research population consisted of seventh-grade students, with the sample being students from class VII A using the CTL learning model and class VII B using the MMP learning model. The independent variable in this study is the learning model, while the dependent variable is the mathematics learning outcomes. The instruments used were a learning outcome test and an observation sheet for the implementation of learning. The results of the study indicate that both learning models, CTL and MMP, are effective in improving students' mathematics learning outcomes. The Wilcoxon test analysis showed that the significance values for both models were less than 0.05, indicating their effectiveness. However, the Mann-Whitney test revealed no significant difference in effectiveness between the two learning models. These findings suggest that both CTL and MMP can be used as effective alternative teaching methods to enhance students' mathematics learning outcomes. This study contributes to the selection of appropriate teaching methods to improve understanding and learning outcomes in mathematics. It is recommended for future researchers to investigate other aspects such as cognitive, psychomotor, or affective domains, and for teachers to consider using CTL and MMP in their teaching activities.]]>

<![CDATA[Weibull distribution is one of the continous probability density function. This distribution is known as a flexible distribution. One of it’s flexibility is can be transformed into other distributions such as exponential distribution depends on parameter selected. Similar to other distribution, Weibull distribution also characterized by cumulative distribution function, mean, variance and moment generating function. One of the well-known application of this distribution is in the field of quality control utilizing reliability data and the well-known tool in quality control is control chart. Therefore, reliability data is not follow normal distribution then Shewhart control chart cannot be applied. To solve this problem, control chart can be formed with the control limit is obtained by Bayesian method. In applying Bayesian method, prior distribution of shape parameter is assumed to be uniform distribution and variables for reliability is assumed to be invers of Weibull distribution. The prior distribution is combine with likelihood function then posterior distribution is obtained which in then used as the control limits by find it’s mean.]]>

<![CDATA[This research was motivated by the many difficulties experienced by students in the mathematics learning process which had an impact on the occurrence of errors in working on mathematics story problems. These errors need to be known so that it is easier to find solutions so that these errors can be minimized. This research aims to determine the types and causes of errors made by students in solving mathematics story problems on single interest and compound interest materials using Polya's steps. This research method is qualitative with descriptive research type. The research subjects consisted of 2 students from 13 class XI TKP SMKN 1 Pariaman students, with the criteria being 1 student each from the medium group and 1 student from the low group. Data collection techniques include tests and interviews. The results of the research show that the percentage of errors made by students in solving mathematics story problems on single interest and compound interest material using Polya steps is: in question number 1, the biggest error made in the step of understanding the problem was 23.08%. Question number 2, the biggest error made during the rechecking step was 15.38%. In question number 3, the biggest mistake made in the step of understanding the problem was 19.23%. The factors that cause students to make mistakes include, not being used to writing information on questions using their own words, not writing down what they know and what is asked in the question correctly, not focusing when working on questions, not being careful in carrying out the calculation process, not being used to checking again, and rushing through the settlement process.]]>
