In a recent theoretical article, I proposed that the efficiency of mitochondrial functioning is the most fundamental biological mechanism contributing to individual differences in general intelligence ("g;" Geary, 2018). The hypothesis accommodates other contributing mechanisms at higher levels of analysis (e.g., brain networks), and is…

This commentary raises and discusses questions based on some of the agreements, disagreements, and themes found in the four chapters on fractions. It considers (1) the importance of tasks that are based in perception and readily available activity in light of an emphasis on problem solving in mathematics education, and the role that theories about…

Quadratic modeling problems are commonplace in high school mathematics courses; they typically situate quadratic patterns of change and their corresponding parabolic graph within real-world contexts. Traditional approaches to this type of problem lend themselves to making connections across different representations (e.g., Garofalo and Trinter…

Cooking is a powerful teaching activity that can be used as an integral part of an early childhood curriculum. In this study, we designed and implemented a cooking-infused program in order to investigate the ways that such a program supports preschoolers' math concepts and skills and their attitudes toward mathematics. Data were collected over…

The field of computational thinking (CT) is developing rapidly, reflecting its importance in the global economy. However, most empirical studies have targeted CT in K-12, thus, little attention has been paid to CT in higher education. The present scoping review identifies and summarizes existing empirical studies on CT assessments in…

Problem-solving skills are essential to help students in expressing their ideas. However, problem posing is a method that can empower problem-solving skills. This study aims to determine the effectiveness of mind mapping assisted with a problem-posing method in online Schoology-based learning. This experimental research used the posttest-only…

Natural science learning achievement is an essential factor in learning outcomes. This research investigated an experimental study that aimed to improve concept science test result in online learning through Jigsaw cooperative learning model and learning style. The research involved the sample of 80 students from junior high school in South…

This study examined auditive and visual working memory and metacognitive knowledge in 92 gifted children (aged between eight and twelve), utilising a pre-test-training-post-test design, known as the cognitive training design. This approach was used to examine the working memory and metacognitive knowledge of gifted children concerning the…

The present study focuses on the assessment of summer robotics camp designed for 7th grade students who were supposed to work on a STEM-related problem through modeling and design activities. It was exclusively investigated the effects of these activities on the STEM-related career interests and knowledge structures of students. The students were…

The purpose of this study was to investigate prospective middle school mathematics teachers' proportional reasoning before and after receiving a practice-based instruction based on proportional reasoning. The Proportional Reasoning Test, semi-structured interviews and observations of student teachings were used to collect data about the…

This study explored whether the computational thinking skills of early elementary-aged students be positively impacted by participation in a robotics-based, classroom intervention. Action research was used to examine the impact of a multifaceted, constructionist, robotics-based intervention on 37 second and third grade students at an elementary…

This paper reports the design, delivery, and evaluation of a mentoring programme which aimed to promote critical thinking and problem-solving skills in Chinese university students. Several new elements in this mentoring programme distinguish it from many previous such programmes within the context of higher education. These new elements include…

Purpose: To date very few studies have explored how second and foreign language (SL/FL) teachers' attitudes affect their grammar teaching expertise acquisition. To shed light on this question, this study looked at what teachers' grammar teaching attitudes are and how these attitudes impact the frequency of explicit goals which are an integral…

Creativity has been identified as a key characteristic that allows students to adapt smoothly to rapid societal and economic changes in the real world. However, Chinese students appear to perform less well in mathematical problem-solving and problem-posing abilities, which are strongly connected to mathematical creativity. Mathematical modelling…

This study aims to analyze the problem-posing skills of primary school mathematics teacher candidates with problem-posing experience and their views on problem posing. The case study, one of the qualitative studies, was used in the study. The study group is ten prospective elementary mathematics teachers who were selected using the purposive…
