This study aimed to describe students’ problem solving skill in nuclear physics course through the implementation of the Nuclear Physics Inquiry Remote Laboratory (NPIRL). This study employed a pre-experimental quantitative method. The research design was one group pretest-posttest design. The subject of the study was 14 physics students at a university in Banjarmasin, South Kalimantan. In selecting the research subjects, the researchers used purposive sampling technique. The instrument used was a problem-solving skills test in the form of an essay consisting of five questions, and each question consisted of six indicators in problem solving skill according to the Osborn-Parnes Creative Problem Solving (CPS). This research found that the N-gain of students' problem solving skill was 0.32 in the medium category. There are four indicators of problem-solving skills that are categorized as medium: objective finding, fact finding, problem finding and idea finding. Two other low-category indicators are solution finding and acceptance finding. Based on these findings, it is concluded that students’ problem solving skill in nuclear physics course through NPIRL have increased.

The objective of this research was to develop an effective Economics learning information system media to improve students’ skill for Macroeconomics problem-solving. It used the research and development method. The Macroeconomics learning information system media was tested by using the quasi experimental research method with before –after design. It was conducted at the Study Program of Economics Education Program, Sebelas Maret University, Surakarta. Its population was 95 students. The findings of the N-Gain showed that the learning result of the experimental group was higher than that of the control group. The criteria of the N-Gain of the experimental group were high gain as much as 3.33%, moderate gain as much as 80% and low gain as much as 16.67%. Meanwhile, the control group did not have a high gain criterion or 0% but moderate gain as much as 46.67% and low gain as much as 53.33%. The score of the calculation on the questionnaire of problem-solving skill of the experimental group students who used the website-based information system media was higher than that of the control group students who did not use such media where the score percentage of the former was 80.61% while that of the latter was 72.18%. With such results, thus, this research was successful in developing a Macroeconomics learning information system media to improve student’s problem solving skill.

The present study aims to examine the effect of inquiry-based problem-solving activities on 60-72 months old children’s problem-solving skills. In the study, the pretest-posttest control group experimental design which is among the quantitative research designs was used. The study group consists of a total of 26 pre-school children as 13 in the experimental and 13 in the control group. The inquiry-based problem-solving activities prepared by the researchers were applied to the experimental group as a total of 30 sessions for 10 weeks and three times a week. Demographic information form and Problem-Solving Skills Scale were used as data collection tools. As a result of the study, it was determined that the problem-solving skill scores of the children in the experimental group were statistically higher than the students in the control group. In other words, inquiry-based problem-solving activities positively affected the problem-solving skills of children.

Abstract: This study aims to determine the problem solving abilities of high school students in solving physics problem topic working and energy. A total of 64 respondents solved physics problem about work and energy which consisted of four questions. The students' answers were evaluated using a rubric consisting of five indicators, namely useful description (UD), physics approach (PA), specific application of physics (SPA), mathematical procedures (MP), and logical progression (LP). The data analysis technique used qualitative descriptive. The results of the analysis show that the score of students' problem solving abilities is in a sufficient category, with the dominant score on indicators UD, PA and SPA. Students get poor score criteria on MP and LP indicators. In this case, students experience some difficulties, among others, students' mistakes in applying physics concepts in mathematical equations, students' mistakes in using equations that are not relevant to the problems presented and students' mistakes in using calculations that do not focus on the problem presented.

Besides learning outcomes, motivation and problem solving skill are the essential indicators for successful learning. Hence, the existence of learning media which considerably follow the advance of technology has been assumed to be able to support the achievement of the indicators mentioned. Thus, the current research aimed at implementing the Augmented Reality (AR) technology to improve students’ problem solving skill, motivation, and learning outcomes. The sample was 56 of eighth graders which covered the both control and experimental classes. This quasi experimental research employed test and observation sheet as the instruments. The data was analyzed using one-way analysis of covariance (ANCOVA). The ANCOVA test results showed that were significance differences of the three indicators (problem solving skills, motivation, and learning outcomes) achieved, in which the experimental class was higher than control class. In conclusion, the AR can influence students’ problem solving skills, motivation, and learning outcomes.
