Although number theory is one of the oldest and most natural mathematical pursuits, some of its topics are not part of the Hungarian high schools’ mathematics curriculum. We examined whether our custom-made web application, including a closely-related task collection and a collaboration interface, may support the problem-solving strategy of students in these tasks, thus supporting their introduction to high school education. For this purpose, we contacted 4 high schools from Jász-Nagykun-Szolnok county (N=352) after developing the website, preparing the number theory task collection, and creating the cooperation interface. Subjects were randomly assigned to an experimental (EXP) or control (CON) group, where members of EXP but not CON and their teachers had access to our website when studying the new number theory topics. We hypothesized that members of EXP will show better test results as compared to CON, indicating the potential benefits of our website during the introduction of new topics. Mann-Whitney U test revealed better overall results in EXP as compared to CON (p < .001). Moreover, Kruskal-Wallis tests showed that subjects EXP vs. CON had higher points in each task (all p < .05), indicating the success of our website. We aim to increase the sample size and to develop additional web applications in our future studies.

The purpose of this research to analyze profile students’ problem solving skill and the implementation of assisted guided inquiry at senior high school. The type of research is used the preliminary research method with data collection techniques such as tests and questionnaires. The data are obtained, analyzed descriptively qualitatively. The results of this study show that only a few students can work on the material using problem-solving strategies (A-Assessing the problem (identifying principles to be used in problem-solving), C-create a drawing (translating words in the form of pictures containing about problem-solving instructions), C-conceptualize strategy (outlining the steps that will be used in solving the problem), E-executing the solution (applying the formula to solve the problem by the steps) and finally S-scrutinize the result (giving a level of confidence and give a reason) in solving dynamic electricity problems. Totally of the students, five students had low problem-solving skills, and 25 students who had moderate problem-solving skills. Totally of the students, five students had low problem-solving skills, and 25 students who had moderate problem-solving skills. The lowest problem-solving strategy value is at point S (scrutinize the result). Implementation of learning models provided is not ideal so that it causes students to be less active so that problem-solving skills are lacking and no laboratory supports the learning process. Students are not introduced to the existence of a virtual laboratory (PhET) as a laboratory replacement. So to improve students' problem-solving skills required appropriate learning methods.

The objective of this research in the find out the effect of extension strategy Inductive (lecture method vs discussion method) and the learning motivation on the student’s knowledge about diversity. The strategy used was a quasi-experiment of 2 x 2 factorial design on the grade-VII students of Public Junior High School – Al-Hikmah Jakarta. The sample 0f 70 students were used, which they were divided in group. The results showed as follows; (1) there is a significant difference between the students knowledge about environment that was taught with lecture method with the students taught with the discussion method, (2) there is an interaction found between instructional inductive strategy and learning motivation on the student’s knowledge about diversity, (3) the students group that process high learning motivation, their knowledge about diversity  is higher with the problem solving strategy than with discussion method, and (4) the low level of learning motivation student’s, their knowledge about diversity is better by lecture method than the discussion method. From the research, the conclusion is that the lecture method can be effective to increase the level of the knowledge about diversity by consideration their learning motivation.

This study was an Action Research which was conducted because the student’s achievement on Mathematics  were still lower than The Minimum Achievement Criteria (KKM). The research was conducted to see whether the Systematic Problem Solving Strategy could improve the student’s learning achievement. The aim of the research was to improve the student’s comprehension on Algebra Limit Function subject In Mathematics, so their learning achievement also improved significantly. The research participants were the students of grade XI IPS 2 SMAN 1 Kerinci. The researcher was helped by a collaborator who was a Math Teacher at the same school. The study was done in two cycles with four stages, (a) Planning (b) Action (c) Observation (d) Reflection. The result of data analysis showed that the student’s average score in cycle 1 was 69 (65%). It became higher in cyle 2 to 83 ( 85%). There was significant improvement seen from the result of cycle 1 compared to cycle 2. It could be concluded that the implementation of Systematic Problem Solving Strategy on Algebra Limit Function subject improved the student’s learning achievement significantly. Therefore, it was suggested to Math Teachers to apply the strategy in teaching  as the alternative solution particularly in Algebra Limit Function subject
