Abstract

The ability to think creatively mathematically, defined as the capacity to generate novel, diverse, and valuable mathematical ideas or solutions to problems with fluency, flexibility, originality, and elaboration, is a crucial skill in facing the challenges of the 21st century. However, a comprehensive understanding of the influencing factors is still limited. This systematic review aims to integrate and synthesize current research on factors influencing mathematical creative thinking abilities from a multidimensional perspective. A systematic search method was conducted on the Scopus database for studies published between 2019 and 2024. The results show the complexity of interactions between cognitive (thinking style, analogical reasoning, computational thinking), affective (self-efficacy, attitudes towards mathematics, self-regulated learning), and contextual (learning approaches, technology integration, background) factors from the 31 articles analyzed. cultural background) in influencing mathematical creativity. The analysis also revealed differences in influencing factors between levels of education from junior high school to college. These results stress how important it is to look at math creativity as a whole. They also have important implications for how math is taught and for future research, such as the need for longitudinal studies and the creation of integrative theoretical models

Abstract

The quality of education in elementary schools must be well maintained so that the next generation of a nation with character is formed. One of the factors that greatly influences the quality of education in elementary schools is good leadership. The principal as the main leader in elementary schools has a very important role in managing the school and leading all members of the school. In the last few decades, transformational leadership theory has become one of the most influential leadership models in education. The transformational approach to leadership has long been considered a productive approach. Transpersonal leadership offers a more humanistic and values-centered approach to addressing the complex challenges faced by today's organizations and societies).

Abstract

The inductive thinking learning model is a learning model based on processing information, with this model students are required to actively learn independently, discover concepts and ideas, and develop critical thinking skills which ultimately influence problem solving. This research aims to determine the effect of the inductive thinking learning model on the mathematical problem solving abilities of PAB Medan Estate Private Vocational School students. This research was carried out in March – May 2024. The research population for all 10th graders was 40 people. The sample was taken by purpose sampling as many as 40 people. This research is quantitative research, the method used in this research is pre-experimental design in the form of one group pretest and posttest. Before being given treatment, a diagnostic test is first carried out to determine the student's metacognitive ability to see how much their metacognition fails in solving statistical problems. Further grouped into high, medium and low metacognitive failure. After being given treatment, namely the inductive thinking learning model assisted by GeoGebra, a posttest was given with the same questions as the pretest in the form of questions describing statistical material. The research results show a significant influence of the GeoGebra-assisted inductive thinking learning model on students' mathematical problem solving abilities.
