Self-perceptions as mechanisms of achievement inequality: evidence across 70 countries.

Children from lower socioeconomic status (SES) backgrounds tend to have more negative self-perceptions. More negative self-perceptions are often related to lower academic achievement. Linking these findings, we asked: Do children's self-perceptions help explain socioeconomic disparities in academic achievement around the world? We addressed this question using data from the 2018 Programme for International Student Assessment (PISA) survey, including n = 520,729 records of 15-year-old students from 70 countries. We studied five self-perceptions (self-perceived competency, self-efficacy, growth mindset, sense of belonging, and fear of failure) and assessed academic achievement in terms of reading achievement. As predicted, across countries, children's self-perceptions jointly and separately partially mediated the association between socioeconomic status and reading achievement, explaining additional 11% (ΔR2 = 0.105) of the variance in reading achievement. The positive mediation effect of self-perceived competency was more pronounced in countries with higher social mobility, indicating the importance of environments that "afford" the use of beneficial self-perceptions. While the results tentatively suggest self-perceptions, in general, to be an important lever to address inequality, interventions targeting self-perceived competency might be particularly effective in counteracting educational inequalities in countries with higher social mobility.

The relation of representational competence and conceptual knowledge in female and male undergraduates.

Background: Representational competence is commonly considered a prerequisite for the acquisition of conceptual knowledge, yet little exploration has been undertaken into the relation between these two constructs. Using an assessment instrument of representational competence with vector fields that functions without confounding topical context, we examined its relation with N = 515 undergraduates' conceptual knowledge about electromagnetism. Results: Applying latent variable modeling, we found that students' representational competence and conceptual knowledge are related yet clearly distinguishable constructs (manifest correlation: r = .54; latent correlation: r = .71). The relation was weaker for female than for male students, which could not be explained by measurement differences between the two groups. There were several students with high representational competence and low conceptual knowledge, but only few students with low representational competence and high conceptual knowledge. Conclusions: These results support the assumption that representational competence is a prerequisite, yet insufficient condition for the acquisition of conceptual knowledge. We provide suggestions for supporting learners in building representational competence, and particularly female learners in utilizing their representational competence to build conceptual knowledge.

Online teaching and learning in higher education: Lessons learned in crisis situations.

In the year 2020, the Covid-19 pandemic turned both private and public life upside down. Teaching and learning at higher education institutions worldwide had to move online on very short notice. This Special Issue focuses on the academic practice of online teaching and learning in higher education in the current time of crisis. Online teaching and learning has been a prominent research topic for the last three decades, but online study programs at universities are still scarce. In this synthesis article, our considerations about online teaching and learning in higher education are positioned in the broad framework of communities of practice (CoPs). We establish a relationship between CoP-concepts and the integrative framework for learning activities involving technology in higher education (the C♭ model), as proposed by Sailer and colleagues in this Special Issue. We continue with some initial thoughts on online teaching and learning in higher education in general, and emergency online teaching and learning more specifically. After an overview of the international research compiled in this Special Issue, we derive a number of general insights on online teaching and learning in higher education, emphasizing, for instance, scaffolding of regulation processes or communication platforms as potential artifacts of an online teaching and learning CoP.

The test of basic Mechanics Conceptual Understanding (bMCU): using Rasch analysis to develop and evaluate an efficient multiple choice test on Newton's mechanics.

BACKGROUND: Valid assessment of the understanding of Newton's mechanics is highly relevant to both physics classrooms and research. Several tests have been developed. What remains missing, however, is an efficient and fair test of conceptual understanding that is adapted to the content taught to secondary school students and that can be validly applied as a pre- and posttest to reflect change. In this paper, we describe the development and evaluation of the test of basic Mechanics Conceptual Understanding (bMCU), which was designed to meet these requirements. RESULTS: In the context of test development, qualitative and quantitative methods, including Rasch analyses, were applied to more than 300 Swiss secondary school students. The final test's conformity to the Rasch model was confirmed with a sample of N = 141 students. We further ascertained the bMCU test's applicability as a change measure. Additionally, the criterion validity of the bMCU test was investigated in a sample of secondary school students (N = 66) and a sample of mechanical engineering students (N = 21). In both samples, the bMCU test was a useful predictor of actual student performance. CONCLUSIONS: The bMCU test proved to enable fair, efficient, and simultaneously rigorous measurement of secondary school students' conceptual understanding of Newton's mechanics. This new instrument might fruitfully be used in both physics classrooms and educational research.
