Naar een beter begrip van de intra-klasse correlatie:Een reactie op de discussiebijdrage “Schoolverschillen en schooleffecten in het voorgezet onderwijs”

In de discussiebijdrage “Schoolverschillen en schooleffecten in het voorgezet onderwijs” (Lek, Feskens, & Scheerens, 2020) wordt gewezen op enkele voorbeelden waarin onderzoekers of beleidsmakers blijk hebben gegeven nog onvoldoende grip te hebben op gepresenteerde intra-klasse correlaties. In deze reactie beschrijf ik de noodzaak om een veel explicieter onderscheid te maken tussen de intra-klasse correlatie als een generieke maat voor de mate van afhankelijkheid van hiërarchisch gestructureerde data en het onderliggende statistische meerniveau-model en benoem ik een aantal misinterpretaties van de intra-klasse correlatie uit de discussiebijdrage

Gender and minority background as moderators of teacher expectation effects on self-concept, subjective task values, and academic performance

Two developments in teacher expectation research formed the basis for the current study. First, researchers have begun investigating the self-fulfilling prophecy effects of teacher expectations on a variety of psycho-social outcomes in addition to the effects on academic achievement. Second, researchers have started to realize that some groups of students appeared to be more vulnerable or susceptible to teacher expectations. The current study aimed to investigate whether students’ gender and minority background were moderators of teacher expectation effects for both academic outcomes and self-concept and subjective task value in the mathematics domain. The study is based on a sample of 1663 students (Grades 6 and 7) in 42 classes from three intermediate schools in New Zealand. Multilevel modeling was applied using MLwiN software. First, after controlling for students’ beginning-of-year mathematics achievement, teacher expectations were higher for Asian and lower for Māori, compared with New Zealand European students. Expectations within the domain of mathematics, however, were higher for girls than for boys. Second, teachers’ beginning-year expectations were predictive of achievement and self-concept of students at end-of-year, after controlling for beginning-of-year achievement and self-concept. Teachers’ expectations were, however, not predictive of end-of-year intrinsic and utility value.Third, we did not find evidence for moderation effects of students’ gender and minority background. These findings imply that despite the roughly similar magnitude of teacher expectation effects for various student groups, teacher expectations may contribute to gaps in students’ achievement and self-concept because of differential expectations at the beginning of the year

Adjusting expectations or maintaining first impressions? The stability of teachers' expectations of students’ mathematics achievement

The issue of teacher expectation stability is crucial in understanding the self-fulfilling prophecies generated by teacher expectations. However, currently there is a lack of empirical evidence related to teacher expectation stability. The aim of the current study was to assess the temporal stability of teacher expectations of their students’ mathematics achievement within the timeframe of one school year. Random-Intercept Cross-Lagged Panel Models were employed based on a sample of 2536 students taught by 89 teachers in New Zealand elementary and middle public schools. Strong rank order stability was found in teacher expectations at the between-student level. Expectation instability was present at the within-student level. Paths from student mathematics achievement to teacher expectations were stronger than the paths in the opposite direction, indicating that teachers adapted their expectations for students to fall in line with student performance and continued to do so throughout the year

Part-time Special Education Predicts Students’ Reading Self-concept Development

The academic self-concept changes from childhood to early adulthood in relation to experiences of capability in different school tasks and comparison with peers. Students in special education have a lower academic self-concept than their peers do, but it is unclear how part-time special education affects self-concept development. In Finnish schools, part-time special education is learning support that is usually provided for 1–2 h/week in small groups. The main aim of this study was exploring the effects of participation in part-time special education and gender on the level and change in three academic self-concept domains (General School, Mathematics and Reading) between the ages of 11 and 13 years (N = 669). Use of the multilevel growth curve model revealed negative linear development in all three self-concept domains from Grades 5 to 7, but participation in part-time special education had a statistically significant positive effect on the development of the Reading self-concept
