The purpose of this research was to describe the students’ error in measurement materials in terms of learning style. This is a qualitative descriptive research. The subject of this research was 6 students with each of the two students in visual learning styles, auditory learning styles, and kinesthetic learning style. The research instruments were questionnaire, test, interview, and observations. Data analysis activities were data reduction, data display, and conclusion drawing/ verification. The technique of data analysis used interactive techniques with these three procedures. The result of this research showed that the students’ error with visual learning styles in solving units, size, and time included material concepts errors and the use of mathematical unit; this is because teachers tend to use the lecture method in learning. The students’ errors with auditory learning style in solving unit, size and time included in interpreting data, determining formulas and errors in counting. The cause of this error is not remembering the concept and hurrying in solving math problems. The students’ error with kinesthetic styles in solving unit, size and time included student errors identifying elements and language interpretation, errors in language use, and conceptual errorst.

Multimedia Interaktif Bab Peluang (MUPEL) are an interactive multimedia to facilitate self-learning in the chapter of Probability. The purpose of this research is: (1) to describe misconception of probability for students who use the interactive multimedia assistance and for students who take the conventional learning and (2) to test the difference in the proportion of decreasing misconception between students who use the interactive multimedia assistance and students who take the conventional learning. The research was conducted at SMAN 2 Kediri. The subjects of this research were students of class XI MIPA 6 as a control class and students of class XI MIPA 8 as an experimental class. The research method that used was Quasi Experiment and the reserach design was Non-Equivalent Pretest-Postest Control Group Design. The instrument of data collection is a diagnostic test of misconception. The data analysis technique used is the proportion test with the Z test and the significance level . The results of this research were: (1) the initial knowledge of the experimental class was 76% still make misconception while the control class 77% still made misconception. After going through the learning process, the experimental class succeeded in reducing misconception to 19%, while the control class succeeded to reduce the misconception only to 45%, and (2) the result of hypothesis testing using the Z-test obtained . Based on these results, the proportion of the reduction in misconception of students with learning facilitated by MUPEL greater than the proportion of the reduction in misconception of students who take conventional learning.

This research was motivated by author's observation at SMP N 1 Ampek Angkek where some of the students was a game players. Although they were played game online, they still got good grades in their school.This study aims to determine the relationship of online games with students' mathematical critical thinking skills held at SMP N 1 Ampek Angkek. This research is a quantitative research with the type of research used is relationship research. The independent variable in this study is online games and the dependent variable is students' critical thinking abilities. The population in this study amounted to 114 students, while the sampling was done by random sampling of 29 students. Based on the results of the research that the researchers did obtained the value of the Pearson Product Moment relationship, r(count) = 0.068 with 0.05 significance level. So that based on the interpretation of the coefficient relationship r value is between 0.00 α = 0.05, it can be concluded that there is correlationship but not significant between online games with mathematical critical thinking skills at SMP N 1 Ampek Angkek.

This study’s aim is to describe mathematics education college students difficulties when doing mathematical proof. This study employs descriptive qualitative methods. This study subjects are 3 mathematic education college students who take real analysis class. The subjects was chosen according to their mathematics proposition proof ability in real analysis. The study was carried out by two step test s, they are written and oral test. Based on the study results we know that: college student with high ability tends to have difficulty in write the information that used to proof in written form, but they still manage to get the right proof; college student with middle ability tends to have difficulty in construct the suitable steps and logics to proof the proposition; and college student with low ability tends to have difficulty in understanding the purpose, meaning, and properties that given by the known proposition in the task. In order to deepen this study results, in the next study, we can employs a standard method to detects difficulty, such as NEA (Newton’s Error Analysis), to find more structured results.
