Academic resilience in 75 education systems: how operationalization and threshold choices shape findings on protective factors

Academic resilience in 75 education systems: how operationalization and threshold choices shape findings on protective factors

Academic resilience—students’ capacity to succeed despite socioeconomic disadvantage—is widely studied, but little consensus exists on how it should be operationalized. Inconsistent definitions make it difficult to compare findings across studies and to draw conclusions about what promotes resilience. The present study asks whether different operationalizations and thresholds lead to different estimates of resilience and different conclusions about its predictors. Using PISA 2018 data from 75 education systems and based on an existing measurement framework, we compared three ways of operationalizing academic resilience: identifying high-achieving disadvantaged students, identifying students who outperform expectations given their socioeconomic status, and predicting achievement within a disadvantaged sample. We applied each at three relative threshold levels of disadvantage and/or high achievement, and assessed the consequences for the estimated prevalence of resilient students and for the associations of four factors (gender, self-perceived reading competence, reading enjoyment, attitude toward learning) with resilience. Prevalence estimates varied nearly fivefold across operationalizations, and rankings of education systems differed substantially. When associations were pooled meta-analytically, they were broadly consistent across operationalizations and threshold levels. When education systems were analyzed separately, however—as is standard in PISA-based research—findings were consistent in only 20–72% of systems, depending on the factor, and threshold level alone altered conclusions in 3–37%. A complementary interaction analysis of risk and protective factors, which requires no threshold, further showed that some motivational factors were associated with a flatter socioeconomic gradient in achievement and others with a steeper one—a pattern that threshold-based definitions cannot detect. Operationalization and threshold levels can meaningfully affect the conclusions studies reach about academic resilience and its predictors. While part of this dependence is mechanical, given how the operationalizations are constructed, the magnitude of this dependence across education systems suggests that findings should not be interpreted independently of the operationalization used to produce them. We provide recommendations for matching operationalization choices to research questions.

Integration or stratification? Cumulative advantage and prestige homophily in the CEEPUS inter-university network

Integration or stratification? Cumulative advantage and prestige homophily in the CEEPUS inter-university network

International student mobility is often framed as an integrative policy instrument, yet mobility systems frequently display durable inequalities and core–periphery structures. This study examines whether a regionally bounded program outside Western Europe’s historical academic core functions primarily as an infrastructure of integration or as a mechanism that reproduces stratification. Using openly accessible administrative records from the CEEPUS, the analysis reconstructs a 20-year longitudinal bipartite network of higher education institutions and thematic network agreements (2005/2006–2024/2025). To identify the micro-mechanisms governing network change, the study estimates a bipartite stochastic actor-oriented model in which institutions adjust their memberships over time, while accounting for the creation and discontinuation of thematic networks. The model tests closure mechanism, cumulative advantage, and selection processes based on geopolitical position, research prestige, and institutional type. Results indicate that cumulative advantage operates strongly at the institutional level: institutions already embedded in multiple thematic networks are substantially more likely to expand further. Stratification is further reinforced by prestige-based activity and prestige homophily, with higher-prestige institutions both participating more and clustering with similarly positioned partners. Relative importance analysis confirms that prestige-based effects constitute the dominant attribute-based force governing tie formation decisions throughout the observation period, consistently outweighing both geopolitical and organizational mechanisms. Geopolitical and organizational boundaries also shape collaboration: institutions in European Union member states expand less on average, yet institutions cluster by shared European Union status, and public and private institutions show both differential activity and strong within-type clustering. Overall, the program expands and stabilizes over time but evolves toward patterned integration rather than uniform cohesion, with stratified collaboration dynamics consistent with persistent academic hierarchy.

Generative AI use and academic achievement: a cross-sectional study of Czech seventh-grade students

Generative AI use and academic achievement: a cross-sectional study of Czech seventh-grade students

This study examines how Generative Artificial Intelligence (GenAI) use is associated with academic achievement among Czech seventh-grade students. Grounded in the deep versus surface approaches to learning framework, we distinguish between the frequency of GenAI use and students’ endorsement of reliance on GenAI over understanding, defined as the belief that knowing how to prompt AI effectively is more important than developing one’s own conceptual understanding. Using cross-sectional survey data from a nationally stratified sample of 2,307 students, we estimated structural equation models predicting IRT-scaled achievement in mathematics and Czech language. Frequency of GenAI use was not positively associated with achievement in either subject. In contrast, stronger endorsement of reliance on GenAI over understanding was consistently and negatively associated with achievement, with a more pronounced relationship in Czech language. Neither GenAI use frequency nor reliance significantly moderated the associations between learning-related dispositions and achievement. These findings suggest that the educational implications of GenAI depend less on how often students use AI tools and more on whether AI is approached as a support for understanding or as a substitute for cognitive engagement. The results contribute to debates on epistemic offloading and the role of AI in shaping students’ orientations toward learning.

Slovak MPs’ response to the 2022 Russian invasion of Ukraine in light of conspiracy theories and the polarization of political discourse

Slovak MPs’ response to the 2022 Russian invasion of Ukraine in light of conspiracy theories and the polarization of political discourse

This study investigates Slovak political discourse on Facebook in the weeks before and after the invasion began. We examine the discourse through the lens of Discourse Network Analysis, combining qualitative content analysis of MPs’ Facebook posts with quantitative bipartite social network analysis. During the two weeks, we retrieved all posts from all MPs who had an active public Facebook page. We manually coded all posts and created a bipartite discourse network consisting of MPs connected to each other via shared discourse codes in two timepoints. We performed a series of exploratory analyses that identified the content of the political discourse, the structure of the political discourse network, and the mechanisms driving the change of the political discourse network. Our results show that the invasion dramatically changed political discourse in Slovakia, with the domestic coalition-opposition struggles losing prominence among the invasion-related topics. The structure of the political discourse network showed a strong coalition-opposition split. While coalition MPs had largely pro-Ukrainian sentiments, opposition MPs largely communicated pro-Russian propaganda. A cluster of opposition MPs consistently spread conspiracy theories both before and after the invasion began, supporting a “conspiracy singularity” theory—the tendency of actors to spread multiple different conspiracy theories and interconnect various conspiracy theories into one overarching narrative. The change of the discourse network at the beginning of the invasion was largely driven by the agenda setting of several parties, agenda reinforcement, and increasing political polarization.

Ukrainian refugees struggling to integrate into Czech school social networks

Ukrainian refugees struggling to integrate into Czech school social networks

We provide a brief insight into the integration of Ukrainian refugees in school social networks in the Czech Republic following the mass migration caused by the Russian invasion of Ukraine. Our sample contains twelve classrooms with a total of 266 students in grades 5 to 9; 21.05% of the students were of Ukrainian origin. We employed multiplex exponential random graph modelling to assess the level to which Ukrainian refugees were integrated within peer networks, capturing both friendship and exclusion ties. We then employed a meta-analytical procedure to aggregate the results from the individual classrooms and a meta-regression to study the relationship between classroom ethnic composition and the level of integration of Ukrainian refugees. We found social networks to be formed heavily along ethnic lines with strong ethnic homophily in friendship ties and a propensity of the Ukrainian students to both send and receive fewer friendship ties than their Czech classmates. We found no evidence that the Ukrainian students sent or received more exclusion ties than their Czech classmates, suggesting that the Ukrainian students did not face explicit rejection from classmates; rather, we saw a tendency of the Ukrainian students to be neglected. Our findings stand in contrast to reports from school headmasters who asserted that the social integration of Ukrainian students was seamless. We further found a higher proportion of Ukrainian students in classrooms to be related to stronger homophilic behaviour and a lower tendency of Ukrainian students to make friends. Our results therefore imply that increased classroom diversity may negatively influence the integration of refugees in social networks.
