The purpose of the present study is to examine the mathematical reasoning and the argumentation process of 7th-grade students during problem-solving and their views on this process. The case study method was employed in line with the purpose. The study group was determined by criterion sampling. Considering the criteria of students' scores on the…

In application-oriented mathematics, particularly in the context of nonlinear system analysis, phase plane analysis through SageMath offers a visual display of the qualitative behaviour of solutions to differential equations without inundating students with cumbersome calculations of the plane-phase. A variety of examples is usually given to…

Using secondary data has many advantages, but there are also many limitations, including the lack of relevant information. This article draws on a previous study that used secondary data to investigate substance use in young, elite athletes. Three types of missing data appeared: missing data, lack of information about the data collection process,…

Preventing panel members from attriting is a fundamental challenge for panel surveys. Research has shown that response behavior in earlier waves (response or nonresponse) is a good predictor of panelists' response behavior in upcoming waves. However, response behavior can be described in greater detail by considering the time until the response is…

Social workers engage with many professionals to address complex social problems. This includes leveraging the power of social work to support quality interventions on interprofessional teams. While generalist social workers are prepared to apply multidisciplinary theoretical frameworks and rely on interprofessional collaboration, specialized…

The Grand Challenges for Social Work were introduced by the American Academy for Social Work & Social Welfare in 2016, which are social problems that are interrelated and "exceedingly complex". We discuss the relevance of complexity theory, operationalized by complex adaptive systems (CAS), to the Grand Challenges. CAS moves beyond…

Developmental researchers commonly utilize longitudinal data to decompose reciprocal and dynamic associations between repeatedly measured constructs to better understand the temporal precedence between constructs. Although the cross-lagged panel model (CLPM) is commonly used in developmental research, it has been criticized for its potential to…

This study explores opportunities to learn definite integrals in three widely used textbooks in the U.S. Definitions, worked examples, and exercise problems were coded using research-based cognitive resources in definite integrals. The results show that limited opportunities for students to explore multiplicative relationship between two…

To become proficient problem solvers, science and engineering students have to acquire the skill of self-regulating their problem-solving processes, a skill supported by their metacognitive abilities. The Disciplinary Learning Companion (DLC) is an online tool designed to scaffold students' use of metacognitive activities through…

A Chinese financial company, through the introduction of action learning methodology, identified core problems from strategy, and finally solved the core strategic problems by forming action learning teams of middle and senior managers, and in the process improved the mindset and capabilities of middle and senior managers. This account of Practice…

Moral and self-conscious emotions like guilt and shame can function as internal negative experiences that punish or deter bad behaviour. Individual differences exist in people's tendency to experience guilt and shame. Being disposed to experience guilt and/or shame may predict students' expectations of their emotional reactions to engaging in…

Large Language Models have recently achieved high performance on many writing tasks. In a recent study, math word problems in Carnegie Learning's MATHia adaptive learning software were rewritten by human authors to improve their clarity and specificity. The randomized experiment found that emerging readers who received the rewritten word problems…

Relations between parental stress and children's behavior problems have been studied, but the role of parenting styles in these relations remains to be clarified. For families of children who are deaf or hard-of-hearing (DHH), exploring the associations among the three factors (i.e., parental stress, parenting styles, and children's behavior…

It is crucial nowadays to predict in a fast and simple manner physical-chemical behaviors like, the size-dependent optical properties of gold nanospheres (Au NSs). The idea behind this experiment is trying to replace (as much as possible) robust and expensive microscopy techniques with UV-vis spectrophotometry and friendly simulations. Students…

In the concluding chapter, "The geo-politics of place: Framing avenues for activism", the preceding chapters are reflected on as conversation starters related to the concept of place in all its manifold meanings at personal, cultural, ideological and political levels. It commences with some reflections on both radicalism and activism,…
