New Knowledge

In our new education curriculum, it has been seen that it is no longer sufficient for students to learn only the achievements, unlike these gains, solution strategies that the student visualizes in his mind and designed by himself are also needed. Mathematical thinking, which is the process of obtaining new information completely different from the student's old knowledge and new knowledge, using it in the solution of the problem, and transforming that knowledge into new knowledge, has become extremely important. MEB asks students for deep mathematical thinking and problem solving skills in all questions they ask in the skill-based tests and student selection exam LGS. In this study, mathematical thinking and problem solving skills of middle school 7th grade students while solving problems will be examined. The research was applied to 241 students in 7 different secondary schools in the province of Bingöl in the Eastern Anatolia Region in the 2020-2021 academic year. In the study, it was investigated by quantitative and qualitative methods whether the mathematical thinking and problem solving skills of the students on rational numbers are related to gender, whether they had pre-school education and daily reading time. In the research, the SPSS 25 package program was used in the analysis of quantitative data, and in the analysis of qualitative data by examining the process steps in the answers from the students. As a result of the research, a statistically significant difference was found between male and female students, and this difference is in favor of female students. According to the findings obtained from the research, no statistically significant difference was found between the students who had and did not have pre-school education. Secondary school 7th grade students’ mathematical thinking and problem solving skills are related to their daily reading time. According to the results, students who read for an hour a day are more successful than students who read for fifteen minutes a day.

Study process in mathematics faces two major problems. First, engineers do not apply directly the problem solving skills of higher mathematics. Second, studying higher mathematics, students get an insufficient idea of its usability. The authors of the paper have worked out frameworks for practical problem solving in mathematics on the basis of didactic ontology in the Moodle computerized learning system (CMS. To determine students' perceptions on practical problem solving in mathematics in e-environment, more than 300 students from the specialties of engineering at the LUA participated in the survey. The survey results showed many students lack basic knowledge in mathematics, therefore they consume a lot of time to learn the basics in higher mathematics and to acquire the skills of practical problem solving in mathematics are less important.

The Relationship

The COVID-19 pandemic has forced millions of students to stay indoors and adapt to the new normal, namely distance learning at home, placing online learning in the spotlight. However, students’ motivation for online learning and its effectiveness in skill development during the COVID-19 pandemic has not been widely studied. This study examined the relationship between students’ fear of COVID-19 and students’ social presence in online learning while investigating the parallel mediating role of student psychological motivation and cognitive problem-solving skills related to online learning. The participants were 472 university students in Malaysia and Pakistan. An online data collection technique using Google Forms was employed. Faculty members of the universities were asked to share the survey with their students. Moreover, using a snowball sampling technique, students were requested to share the survey with their friends. SPSS Statistics (Version 21)  was employed to do preliminary data analysis, AMOS (Version 21) software was used to conduct confirmatory factor analysis using a maximum likelihood estimation, and Hayes’ PROCESS model was used to examine proposed hypotheses. The results show that only cognitive problem solving mediates the relationship between fear of COVID-19 and students’ social presence in online learning in Malaysian samples. In Pakistan, cognitive problem solving and psychological motivation mediate the relationship between fear of COVID-19 and students’ social presence in online learning. The study found that developing cognitive problem-solving skills and providing psychological motivation could enhance their engagement with online learning.

This study aims to investigate the effect of Science, Technology, Engineering, and Mathematics-Project Based Learning (STEM-PjBL) and discovery learning on students' problem-solving abilities. The research is a Quasi-Experiment with a Nonequivalent Pretest-Posttest Control Group Design. The participants involved are 53 students of class X from a high school in Malang, where 28 students studied with STEM-PjBL, and 25 students studied with discovery learning. This research was conducted on the subject of impulse and momentum. In this analysis, researchers have developed problem-solving tools with a particular field approach to impulse and momentum topics in order to obtain an instrument with a reliability of  0.81. This instrument collects student problem-solving data before and after learning both in the experimental class and in the comparison class. Problem-solving skills data were analyzed using descriptive statistics and inferential statistics. The results showed a significant difference in the scores of students' problem-solving abilities in the experimental class and the comparison class (p<0.05). The problem-solving ability in the experimental class (Md=78.74) was higher than the comparison class (Md=70.00). In STEM-PjBL learning, students are better trained and challenged to solve problems in everyday life. Compared to the comparison class, learning in the experimental class is more able to accommodate students' ideas and make students more interested in learning. In conclusion, STEM-PjBL has a significant positive effect on improving students' problem-solving abilities rather than discovery learning.
