Presenting novices with examples and problems is an effective and efficient way to acquire new problem-solving skills. Nowadays, examples and problems are increasingly presented in computer-based learning environments, in which learners often have to self-regulate their learning (i.e., choose what type of task to work on and when). Yet, it is…

Education for Sustainable Development (ESD) is a teaching and learning approach that is based on the principles that underpin sustainability and applies to all levels of education. However, there is a scarcity of research on the integration of curricula with ESD. In this study, secondary school curricula in Germany (Bavaria) (geography, nature and…

Anger and aggressive behaviour are part of everyday school-life and have been reported to be negatively associated with student well-being and academic performance. School-based interventions, developed to target anger and aggressive behaviour, are scarce. One such Danish intervention, the so-called Mini-Diamond, has been developed and implemented…

This study examined the effect of attending Pre-K 4 SA on students' educational achievement in third and fourth grades. Pre-K 4 SA is a high-quality pre-kindergarten (pre-K) program in San Antonio that meets all quality standards defined by the National Institute for Early Education Research (NIEER). The results showed that distance to Pre-K 4 SA…

Background: A large evidence base suggests that without effective early intervention, young children who exhibit persistent challenging behavior often face a host of long-term social and academic challenges (Bulotsky-Shearer & Fantuzzo, 2011; Hauser-Cram & Woodman, 2016; Kazdin, 1995; Lane et al., 2008; Miller et al., 2017). Challenging…

The purpose of this study was to examine the effects of algebraic equation solving intervention for sixth graders with mathematics learning difficulties (MD). A total of 48 students with MD were randomly assigned to either the algebraic equation solving intervention, "Mystery Math" (n = 24) or control condition (n = 24). The…

Scientific writing is essential for students to express their idea and to report their research. Problem-based learning model directs students to solve problems and report them in the form of scientific articles. The report is written logically and systematically. The research used a quasi-experiment method with 62 students as participants. The…

Syntactic language features of word problems have often been identified by assessment studies and interview studies as potential obstacles in word problem solving. However, students' processes of noticing and interpreting these features have only rarely been investigated in depth because noticing is hard to investigate. Eye-tracking methodology…

The aim of this study is to examine the problem-solving processes and problem-posing skills of pre-service mathematics teachers, which consists of four stages (understanding the problem, preparing a plan for the solution, applying the plan, evaluating) defined by Polya (1997) with the progressive scoring scale based on the alternative assessment…

The teaching guides that complement textbooks have key importance in the assessment of competence in problem solving, because these materials contain the assessment tools that teachers frequently use to quantify the achievements of their students. In this paper, we set two aims: to analyze which curriculum contents are given priority in the…

With implemented school closures, the global crisis of COVID-19 has caused drastic changes in the dynamics and routines of children and their families. The rapid transition to homeschooling and social distancing measures have been particularly challenging for schoolchildren and their parents. In the adverse situation of COVID-19, children are more…

There has been sustained research interest in the role of early career researchers in advancing the field and the challenges that they face. However, efforts to document lived experiences of researchers working in a specific research area within science education have been scarce. This paper considers the meaning of innovation in the context of…

Early childhood educators play a critical role in the lives of young children, especially through their sensitive interactions. Educators' capacities to engage in high-quality interactions are shaped by their mental health. Studies examining early childhood educators' mental health often focus on psychopathology or negative aspects of mental…

A 12-episode constructivist teaching experiment with two pairs of elementary preservice teachers was conducted to examine how they reason distributively and proportionally. Specifically, I studied how prospective teachers reason with ratios as multiplicative comparisons. Prospective teachers solved different problems in one specific context (Step…

Decomposition of organic matter controls the flow of carbon and nutrients in terrestrial and aquatic ecosystems. Several kinetic laws have been proposed to describe decomposition rates, but they neglect adaptation of the microbial decomposer to environmental conditions. Here we formalise decomposition as an optimal control problem by assuming that…
