Linearity Test

This study aims to determine the effect of students' mathematical dispositions on mathematical problem solving abilities of students in class VII of SMP. The type of research used is quantitative. The sample in this study was class VII A, amounting to 30 people who were selected using simple random sampling from 6 existing classes. The type of data in this research is primary data with data collection used using a disposition questionnaire consisting of 28 items and tests consisting of 5 items of description. Testing the hypothesis in this study using a simple regression test. After the data is analyzed the regression equation is obtained as follows: Y = 16,312 + 0.523X. before testing the hypothesis, the data normality test and linearity test were carried out. Based on the data analysis, it was found that the t-test = 3.296 with significance = 0.003 and table = 2.048. then t count = 3.296> 2.048 = t table means that data is normally distributed. To see the achievement of the disposition indicators of junior high school students in the junior high school class, the average of each indicator is calculated and the achievement of the mathematical disposition indicator is 50.08%. Whereas for grouping mathematical dispositions, problem solving abilities obtained the highest dispositions having an average of 63.04, moderate dispositions having an average of 43.56, and low dispositions having an average of 40.51. Thus, it can be concluded that there is an influence of mathematical disposition on mathematical problem solving abilities of students of junior high school class.

This research aims to develop and produce digital teaching materials products using Macromedia flash application that are valid, practical and effective. This research method refers to a 4D development, and disseminate. Research instruments in the form of validation sheets by material expert and media expert to measure validity; questionnaires of learners; responses to measure practicality; and test of learning outcomes to measure effectiveness. The trial of teaching materials was conducted to class VII learners at SMPN 6 Makassar. The result showed that digital teaching materials developed using Macromedia flash applications in class VII junior high school comparison materials had valid criteria with validity score of 3.70 for the material and 3.50 for media, practically score of 3.60 for small groups and 3.51 for large groups, and effective with an effectiveness score of 90% for small groups and 86%.

Misconception is a wrong concept because it bring contradicts concept with experts concept. Misconception occur because students develop their own understanding based on experience, what they seeing and hearing, to understand a concept. Misconceptions that occur in students, before repairs must be identified first. The purpose of this study was to determine students' misconceptions about photosynthesis in Class VII Sutera junior High School. The sample of this research was 40 students of class VII. This type of research is descriptive. The technique using diagnostic test two-tier multiple choice. Test diagnostic used to identify student errors because it can measure 2 levels of high-level thinking skills, scoring is easy, fast and objective, and the opportunity for students to guess answers less. Based on the results of the study, it was found that the highest misconception was found in organisms that could carry out photosynthesis at 87.5%, organs that played a role in photosynthesis 44.5%, photosynthetic processes 42.5%, experiments with photosynthetic processes 25%, and factors affect photosynthesis 38.125%. Thus it can be concluded, that there is a misconception in Class VII Sutera Junior High School about photosynthetic material with varying percentages.
