Data science programming presents many challenges for programmers entering the field. Roughly, data science programming can be broken up into several activities: data wrangling, analysis, modeling, or visualization. Data wrangling is an important first step that involves cleaning and shaping tabular data--or dataframes--into a form amenable for…

This study investigated the effects of (1) proximal grouping of numbers; (2) problem-solving goals to make 100; and (3) prior knowledge on students' initial solution strategies in an interactive online mathematics game. In this game, students transformed an initial expression into a perceptually different but mathematically equivalent goal state.…

When the author began his career as a school librarian, he took time to live with the collection and the school library the way it was inherited, with systems that were already in place. And during that first year, he observed. That period of observation and living with things as they were allowed him to start innovating and problem-solving from…

This conceptual paper discusses two frameworks, developed independently by the lead author, that will provide the conceptual foundation for the identification and evaluation of mental computation strategies students demonstrate during an upcoming research project entitled Mental Computation in Year 5. These frameworks will be used by the lead…

Place value is one of the 'big ideas' in number and plays a critical role in helping students develop their number sense, problem solving and computation skills. Yet, the elegant simplicity of our place value system belies the abstract nature of the construct. This paper presents data from 606 Year 3-6 students (ages 8-12) from two metropolitan…

In numerical cognition research, the operational momentum (OM) phenomenon (tendency to overestimate the results of addition and/or binding addition to the right side and underestimating subtraction and/or binding it to the left side) can help illuminate the most basic representations and processes of mental arithmetic and their development. This…

Purpose: Data was obtained from students from 39 universities in 24 countries, part of a large experiential exercise, X-Culture, who worked remotely in cross-cultural teams to solve business problems. The purpose of this study is to develop and test, using structural equation modeling, a conceptual model that identifies the determinants of…

Despite the demands for innovation, adaptability, and creative problem-solving as seen in the fourth Industrial Revolution, many institutions of higher education struggle to center creativity in the learning experience. This qualitative, grounded theory study examines how first-year courses using design thinking approaches can introduce creativity…

The purpose of this mixed-methods sequential explanatory study is two-fold. It is intended first, to determine the effect of problem-based learning (PBL) on problem-solving skills, and second, to reveal student opinions regarding PBL. A quasi-experimental design with a pre-test and post-test control group was preferred in the quantitative…

The purpose of this study was to examine the mathematical creativity of gifted and non-gifted students through the indicators of creativity (fluency, flexibility, and originality). The study involved 12 secondary school students (six gifted and six non-gifted) from different cities in the Black Sea Region of Türkiye. The data were collected…

This article examines different rationalities for parental involvement in their children's early childhood education and care (ECEC). Starting from Foucault's governmentality and the context of the transforming and diversifying Czech preschool system, it analyzes parents' rationalities for their involvement in ECEC and discusses how they relate to…

Background & Aims: Cognitive load theory assumes that the higher the learner's prior knowledge (i.e., the more expert the learner), the lower the intrinsic cognitive load (complexity) experienced for a given problem. While this is the case in many scenarios, there can be cases in which the converse is also true, resulting in more expert…

Pedigree problems are typical tasks in school genetics classes. However, they are perceived as difficult and often are not successfully completed. Therefore, the purpose of this study is to determine relevant factors that might have an impact on success in pedigree analysis. Based on previous research, we investigate the influence of the…

This study aimed to determine whether there was a correlation between school administrators' solution-focused approach and their preferences for conflict management strategies. The research design of this study was the correlational survey, which is one of the quantitative research designs. The sample of this study included 248 school…
