One of the impacts of the Covid-19 pandemic on the education sector is changing the face-to-face learning system into online learning. This research was conducted to find out how the pattern of parental assistance in online learning at the Elementary School (SD) level. The research data were obtained using a questionnaire given online via Google Form to 100 parents of elementary school students who were selected by random sampling method. Based on the research results, it is concluded that parents play a role in assisting the learning process of children at home. Most parents cannot fully assist their children in learning because both parents have to work. As a solution, other family members can accompany their children to learn. Not a few parents also entrust tutors to accompany their children to study because parents do not understand the material provided. Parents have high hopes that teachers in explaining the material are not too fast so that students can understand the material better, communication between students and teachers is more intense, material is integrated with student life, and students acquire skills and character education.

The purpose of this research to determine whether cooperative learning model through the use of snowball throwing prized chart is more effective than conventional learning model to mathematics learning outcomes seventh grade students of SMP Negeri 11 Yogyakarta.Â The population consisted of 137 students were divided into four classes. The sample selection is in this study using cluster random sampling technique. Data analysis techniques in this study using t-test, and than compares tobservatedÂ with ttable, with df = n1 + n2 -2, and Î± = 5%. If tobservatedÂ Â ttable , then Ho is refused, meaning that the average score of the achievement of the experimental classes are better than the average score of the achievement of the control class. The research is found that the average achievement scores (gain) = 4.64 and the experimental class average achievement scores (gain) control class = 3.48. Obtained with Â and Â tobservated = 2,214 > ttable = 1,645 then Ho is refused, it means the average achievement scores (gain) achievement test on the subject of rectangular and square in the experimental classes are better than the control class. So it can be concluded that the cooperative learning model through the use of snowball throwing prized chart is more effective than conventional learning model to mathematics learning outcomes seventh grade students of SMP Negeri 11 Yogyakarta.

This study aims to determine differences in problem solving skills with the learningcycle and conventional models in Mathematics Education Programm UST. This study design is a randomized pretest-posttest control group design. The sample was a student of fourth semester. Data collected by the testing techniques that comprise the initial test (pretest) and final test (posttest). Instruments in this research is a test instrument that consists of 4 questions about the pretest and posttest 5. The trials instruments include validity, different power, test difficulty levels, and reliability testing. Data analysis techniques include equality test average, which is the prerequisite test normality and homogeneity test, and analysis of the N gain using the t test. The results showed that there are differences in problem-solving abilities with learning model and conventional learning cycle. It was seen from the significant value of the index gain = 0.000 <Î± = 0:05. Based on the average ability of mathematical reasoning and problem solving shows that the model Learning Cycle better than conventional models.

The descriptive objectives of this research are (1) determine the trend of interesting in learning, facilities, students perception to teachers ability and mathematics achievement, (2) determine the correlation between interesting in learning, facilities, students perception to teachers ability and mathematics achievement from all variables also each variable. This is ex post facto research. The population are the seven grade of Junior High School student in Kasihan Bantul. The sample are taken with cluster random sampling. The data are obtained through test and questionnaire. The requirements analysis are normality tes, linierity tes and multikolinierity tes. The analysis of data used multiple regression analysis to determine the correlation for all variables and partial correlation analysis to determine the correlation for each variable. The result showed that the trend of interesting in learning, facilities, students perception to teachers ability is very high category and mathematics achievement high category. The result show that the value of R = 0,498, R2 = 0,248 with Fobserve = 13,068 and sign = 0,000 < 0,05, means there is a possitive and significant correlation between interesting in learning, facilities, students perception to teachers ability and mathematics achievement.

This study aims to (1) design an electronic mathematical student worksheet based on Tri N on the subject of integers and fractions; (2) knowing the level of validity of the electronic mathematics student worksheets based on the Tri N. The stages of this research use Define, Design, and Develop, which are part of the 4D stage of RND. The data collection technique used at the define stage is documentation and journal analysis, while at the develop stage is a validation sheet filled out by validators (math teachers and mathematics education lecturers). The data analysis technique carried out at the define and design stages is descriptive qualitative, while at the develop stage is a quantitative descriptive analysis using Aiken validity. The results showed that the design process obtained a mathematics learning tool in the form of Mathematics E-LKPD which was suitable for use. This can be seen from the results of the V-Aiken calculation obtained in the range of 0.691 to 0.988.
