We report on a scaled-up mathematics intervention in preschool classes (children age six) in Sweden. In the intervention, teachers at seven schools in four municipalities implemented the Thinking, Reasoning and Counting in Preschool Class (TRC) teacher guide in their teaching of 254 students. Results are compared to a previous randomized…

The purpose of this paper is to follow the reasoning of high school students when asked to explain the standard trigonometric limit lim/[theta][right arrow] sin[theta]/[theta]. An observational study was conducted in four different phases in order to investigate if visualization, by means of an interactive technology environment (Geogebra), can…

This study revisits the seminal question of the effectiveness of education for sustainable development (ESD) by using a novel longitudinal approach. Scholarly attention in the past decade has been increasingly directed towards the concept of action competence for sustainability. However, little is still known about the effects of ESD as a teaching…

The use of social media such as Twitter has gained popularity in education during the COVID-19 pandemic. This study included 22 high-quality peer-reviewed journal articles for the meta-analysis. The authors reveal that there are no significant differences in teaching effectiveness between the Twitter and non-Twitter-assisted learning approaches.…

This study revisits the seminal question of the effectiveness of education for sustainable development (ESD) by adopting a novel approach. Little is known about the effects of ESD as a teaching approach to develop students' action competence for sustainability. This study therefore adopts a three-wave longitudinal design, tapping into the…

The outcomes of a longitudinal randomized number sense intervention including pre-, post- and follow-up tests are reported. The intervention was conducted in Grade 0 when children were six years old. Using Concrete-Representational-Abstract principles, a structured explicit 10-week program focusing on numbers and collective reasoning about…

The purposes of this study are to examine the relation between playing commercial-off-the-shelf (COTS) games in the wild and L2 English vocabulary and to offer comparisons with non-gamers' vocabulary. Data were collected from two samples of teenage L2 English learners in Sweden, Sample A (N = 1,069) and Sample B (N = 16). Questionnaires and…

This study introduces an approach to providing corrective feedback to L2 learners termed analogy-based corrective feedback that is motivated by analogical learning theories and syntactic alignment in dialogue. Learners are presented with a structurally similar synonymous version of their output where the erroneous form is corrected, and they must…

Many studies have been made on the impact of supplemental instruction in supported courses, with most showing significantly better examination results for students attending supplemental instruction in comparison to those who do not. However, remarkably little attention has been devoted to following up whether the benefits of supplemental…

This article contains an analysis of policies aimed at increasing the participation of adults in higher education (HE) in seven countries (NL, DK, SE, UK, BE Flanders, DE and the state of California in the USA). In order to maintain their economic competitiveness, many countries have developed policies to increase the participation of adults in…

A three year longitudinal intervention study is presented where two conditions of reading instruction are compared. In a base condition six teachers--four in the experimental groups and two in the control groups--and their students in grade 4-6 discussed expository texts during a regular lesson. The discussions, which took place in small groups,…

This paper investigates learner response to a novel kind of intonation feedback generated from speech analysis. Instead of displays of pitch curves, our feedback is flashing lights that show how much pitch variation the speaker has produced. The variable used to generate the feedback is the standard deviation of fundamental frequency as measured…

Before 1970, no mixed-age groups existed in Swedish nursery schools. By 1991, 43 percent of children enrolled in nursery school were in mixed-age groups of ages 1 to 6 years, and 37 percent were in groups of children ages 3 to 6 years. Mixed-age groups are assumed to have advantages, including positive influences on learning and social…
