Review of Brief School-Based Positive Psychological Interventions: a Taster for Teachers and Educators

Research studies looking into the effects of positive psychology interventions (PPIs) implemented in classrooms have yielded promising results, not only in terms of student well-being but also in terms of academic outcomes, school climate, and teacher well-being. However, a number of PPIs require relatively high levels of commitment from school administrators and teachers to put into place. This may result in many teachers dismissing PPIs across the board as too complicated to implement. The goal of the present article is thus to present a review of brief PPIs (BPPIs) based on positive psychology research in order to encourage involvement in such interventions at school. The BPPIs presented here have been categorized into four sections according to established areas of research in positive psychology, mindfulness, gratitude, strengths, and positive relationships, with precise examples of practices which have been successfully implemented and have demonstrated diverse benefits on student learning and well-being. The potential limitations of such interventions are also highlighted in order to foster best practices and cross-cultural adaptations of such projects.     

Boon and bane of being sure: the effect of performance certainty and expectancy on task performance

Previous research has suggested certainty to be an important factor when investigating effects of level of expectancies on future behavior. With the present study, we addressed the interplay of expectancy certainty and level of expectancies regarding task performance. We assumed that certain performance expectancies provide a better basis for the regulation of persistence and, therefore, lead to improved performance when people expect to perform well. However, when people have bad performance expectations, being certain (compared to being uncertain) about this expectation decreases motivation to work hard on the task because it is assumed it will not pay off anyway. Accordingly, in our study, we found that the performance of participants with high performance expectancies increased with increasing expectancy certainty. By contrast, performance of participants with low performance expectancies decreased with increasing expectancy certainty. Additionally, certainty and expectancy were shown to be unrelated, supporting the idea that they are independent constructs.     

Response to intervention

This introduction provides a context for the other articles included in this volume. The Learning Disabilities Initiative, a multiyear effort at the Office of Special Education Programs, has been focused on a more efficient and effective process for determining specific learning disability eligibility.     

What is implied when researchers claim to use a theory?

The focus of this article is on the use of theories and on what we imply when we in research claim to use a theory. In this article, diverse uses of one theory will be illustrated with reference to 10 different studies. The aim is not to evaluate or judge how the theory is used in these studies, but to discuss how the diverse uses of one and the same theory may infer very different things in research. Questions are raised about what happens with the hierarchy and the coherence of an argument and what conclusions can be drawn when only some parts of a theory are used.     

Introduction: problematizing voice and representation in youth media production

This introduction to the special issue Voice and representation in youth media production in educational settings: transnational dialogues presents a discussion of the notions of voice and representation and an overview of the contributions to this issue, and reflects on the possibilities and limits for a transnational dialogue within current academic traditions and publishing practices.     

Students’ engagement in different STEM learning environments: integrated STEM education as promising practice?

In this paper, we explore how students’ engagement varies in different STEM (Science, Technology, Engineering, Mathematics) learning environments. More specifically, we focus on the significance of a learning environment applying an integrated STEM (iSTEM) approach and the significance of STEM learning environments’ student-centredness. Moreover, we explore the relative importance of different student-centred principles (lesson plan and implementation, communicative interactions, student-teacher relationships) for students’ engagement in the STEM learning environment. Applying a mixed-method approach, we draw from observational data of 24 STEM lessons in combination with data from seven focus groups with 67 grade 9 students. The quantitative findings, based on the observational data, show that a learning environment applying an iSTEM approach seems to support students’ engagement. Further investigation made it clear that the student-centredness in this learning environment is especially significant. Regarding the specific student-centred principles, all principles had a significant impact on students’ engagement. The focus group data make clear that, besides student-centredness, the integrative aspect and the use of authentic real-world problems in iSTEM can also be engaging for students. These results indicate that iSTEM is a good practice to engage students in the STEM learning environment, as it facilitates teachers’ implementation of a general student-centred approach.     

What Does Prone Skateboarding in the Newborn Tell Us About the Ontogeny of Human Locomotion?

The crawling behavior of sixty 2-day-old newborns was studied while they were supported prone on a mini skateboard and on a pediatric mattress without additional support. Analyses of the number and types of limb movements and their characteristics, the coactivation of limb pairs, and the displacement across the surface, revealed that newborns can crawl with locomotor patterns similar to those documented during quadrupedal locomotion in animals and human adults. This was particularly apparent on the skateboard. This discovery suggests that locomotor circuitry underlying quadrupedal locomotion develops during fetal life. Drawing upon other evidence for a quadrupedal organization underlying bipedal gait, we argue that early quadrupedal training may enhance interventions designed to hasten the onset of independent walking.     

Three- to Four-Year-Old Children Rapidly Adapt Their Predictions and Use Them to Learn Novel Word Meanings

Adults create and update predictions about what speakers will say next. This study asks whether prediction can drive language acquisition, by testing whether 3- to 4-year-old children (n = 45) adapt to recent information when learning novel words. The study used a syntactic context which can precede both nouns and verbs to manipulate children's predictions about what syntactic category will follow. Children for whom the syntactic context predicted verbs were more likely to infer that a novel word appearing in this context referred to an action, than children for whom it predicted nouns. This suggests that children make rapid changes to their predictions, and use this information to learn novel information, supporting the role of prediction in language acquisition.     

The impact of formative and shared or co-assessment on the acquisition of transversal competences in higher education

The use of formative and shared or co-assessment has been shown to improve the motivation, involvement and learning of university students. The aim of this study is to analyse the effect that implementing these processes has on university students’ perception of their acquisition of transversal competences. The participants in the study were 1021 students from five Spanish universities taking degree courses in primary education or physical education and sport science. They all experienced formative and shared or co-assessment throughout a complete academic year of their courses. For the data collection, a Self-Perception Scale of Transversal Competences was created, which had adequate values of reliability and validity. Using a transversal design (inter-subjects), inferential statistical analysis was undertaken of the differences in means between the perception of a range of transversal competences before and after the course. The results show significant perceived improvements at the end of the course for most of the competences analysed, which indicates, among other thing, the value and importance of this type of assessment for the educational process.
