This paper describes and analyses the results of research into the learning experiences of young people in Germany who sponsor a child living in the Global South as part of their school activities. First, the research context and methodological approach is presented. A qualitative-reconstructive design was applied using the documentary method of…

Previous research has found that different presentations of the same concept can result in different patterns of transfer to isomorphic instances of that concept. Much of this work has framed these effects in terms of advantages and disadvantages of concreteness or abstractness. We note that mathematics is a richly structured field, with deeply…

Policymakers have grown increasingly interested in how experimental results may generalize to a larger population. However, recently developed propensity score-based methods are limited by small sample sizes, where the experimental study is generalized to a population that is at least 20 times larger. This is particularly problematic for methods…

This study reports errors and misconceptions about division operation in fractions made by eighth-grade students. To investigate these errors and misconceptions, the study examined students' understanding of division operation in fractions using a questionnaire and expectation table. Students' misconceptions were determined for each question and…

Purpose: To investigate the effect of generalization of engagement in parkour from physical education (PE) to organized and supervised recess on voluntary participation and moderate-to-vigorous physical activity (MVPA). Method: Children received a 6-day parkour unit in PE and every two lessons they could voluntarily participate in 20-min parkour…

The understanding and generalisation of causality are important thinking abilities, as they form the basis for a person's activity. Researchers exploring these abilities do not have a unified opinion regarding the age of children when they develop causative understanding and its determinant factors (e.g. age, prior knowledge, the content of a…

Learning trajectories are built upon progressions of mathematical understandings that are typical of the general population of students. As such, they are useful frameworks for exploring how understandings of diverse learners may be similar or different from their peers, which has implications for tailoring instruction. The purpose of this…

The acquisition of a new morphological rule can be influenced by numerous factors, including the type of feedback provided during learning. The present study aimed to test the effect of different feedback types on children's ability to learn and generalize an artificial morphological rule (AMR). Two groups of eight-year-olds learned to judge and…

The present paper offers a definition of peer assessment and then reviews the major syntheses on its effectiveness. However, the main part of this paper is preoccupied with how to do PA successfully. A typology of 44 elements explains the differences between the many types of peer assessment. Then a theoretical model outlines some of the processes…

Foreign language learning in the third age is one of the popular activities among the elderly. The question remains as to how to teach a foreign language to older adults properly. The first objective of this review was to identify suitable pedagogical approaches, teaching methods, or strategies for teaching foreign languages to third-age learners.…

This article reports two intervention studies testing the effects of plurilingual teaching on grammatical development among primary-school students learning English as a foreign language (FL). In a pre-posttest control-group design, more than 200 9-10-year old majority language German and minority language students received plurilingual FL…

This paper is concerned with developing a new class of generalized numbers. The main advantage of this class is that it generalizes the two classes of generalized Fibonacci numbers and generalized Pell numbers. Some new identities involving these generalized numbers are obtained. In addition, the two well-known identities of Sury and Marques which…

We taught three children diagnosed with autism spectrum disorder to request help using an interrupted chain procedure during which we manipulated task materials such that the child was either incapable or capable of independently completing a link of a behavior chain. We initially observed undesirable generalization of requests for help during…

Constructivist views of cognitive development often converge on 2 key points: (1) the child's goal is to build large conceptual structures for understanding the world, and (2) the child plays an active role in developing these structures. While previous research has demonstrated that young children show a precocious capacity for concept and theory…

The article presents a typology of statements that can be made about discourse data. The classification is based on two parameters: level of generality and level of interpretation. Each of these is operationalized into three discrete levels, to yield a nine-cell table containing types of statements going from the presentation of a single case to…
