Educational Leadership and Pupil Achievement: The Choice of a Valid Conceptual Model to Test Effects in School Effectiveness Research.

School effectiveness research often uses multilevel models in which only direct effects of characteristics of schools on pupil achievement are modelled. Recently, more attention is given to conceptual models that assume indirect and antecedent effects. In this paper, we elaborate on these models and show that the findings from school effectiveness research are influenced by the conceptual model underlying the analyses. We do this by focusing on the effect of “integrated leadership” on 2 outcome measures: mathematics achievement and mother tongue achievement. Four different conceptual models will be tested by means of multilevel structural equation modelling. Therefore we use data from a school effectiveness research in Flanders (850 fourth graders and 847 sixth graders within 47 schools). The results of these analyses show that the conclusion whether integrated leadership has an effect or not on pupil achievement, is dependent on the choice of the conceptual model.

Longitudinal Measurement Invariance of Likert-Type Learning Strategy Scales: Are We Using the Same Ruler at Each Wave?.

Whether or not learning strategies change during the course of higher education is an important topic in the Student Approaches to Learning field. However, there is a dearth of any empirical evaluations in the literature as to whether or not the instruments in this research domain measure equivalently over time. Therefore, this study details the procedure of longitudinal measurement invariance testing of self-report Likert-type scales, using the case of learning strategies. The sample consists of 245 University College students who filled out the Inventory of Learning Styles—Short Version three times. Using the WLSMV estimator to take into account the ordinal nature of the data, a series of models with progressively more stringent constraints were estimated using Mplus 6.1. The results indicate that longitudinal measurement invariance holds for all but two learning strategy scales. The implications for longitudinal analysis using scales with varying degrees of measurement invariance are discussed.

Modeling change in learning strategies throughout higher education: a multi-indicator latent growth perspective.

The change in learning strategies during higher education is an important topic of research in the Student Approaches to Learning field. Although the studies on this topic are increasingly longitudinal, analyses have continued to rely primarily on traditional statistical methods. The present research is innovative in the way it uses a multi-indicator latent growth analysis in order to more accurately estimate the general and differential development in learning strategy scales. Moreover, the predictive strength of the latent growth models are estimated. The sample consists of one cohort of Flemish University College students, 245 of whom participated in the three measurement waves by filling out the processing and regulation strategies scales of the Inventory of Learning Styles – Short Versions. Independent-samples t-tests revealed that the longitudinal group is a non-random subset of students starting University College. For each scale, a multi-indicator latent growth model is estimated using Mplus 6.1. Results suggest that, on average, during higher education, students persisting in their studies in a non-delayed manner seem to shift towards high-quality learning and away from undirected and surface-oriented learning. Moreover, students from the longitudinal group are found to vary in their initial levels, while, unexpectedly, not in their change over time. Although the growth models fit the data well, significant residual variances in the latent factors remain.

Examining the Cross-Cultural Sensitivity of the Revised Two-Factor Study Process Questionnaire (R-SPQ-2F) and Validation of a Dutch Version

The Revised Two-Factor Study Process Questionnaire (R-SPQ-2F) is used to examine students’ study approaches in higher education. The questionnaire assumes to measure two factors: a deep and a surface study approach. Analyses into the validity and reliability of the original English R-SPQ-2F yielded positive results. In this study, we examined the degree to which these positive results can also be found for the Dutch version that we developed. By comparing our results with the results of earlier studies in different cultures, we conclude cross-cultural sensitivity is an important point to be borne in mind when using the R-SPQ-2F. Our research supports the validity and reliability of our Dutch version of the R-SPQ-2F.

The Relation between Order of Acquisition, Segmental Frequency and Function: The Case of Word-Initial Consonants in Dutch

The impact of input frequency (IF) and functional load (FL) of segments in the ambient language on the acquisition order of word-initial consonants is investigated. Several definitions of IF/FL are compared and implemented. The impact of IF/FL and their components are computed using a longitudinal corpus of interactions between thirty Dutch-speaking children (age range: 0 ; 6-2 ; 0) and their primary caretaker(s). The corpus study reveals significant correlations between IF/FL and acquisition order. The highest predictive values are found for the token frequency of segments, and for FL computed on minimally different word types in child-directed speech. Although IF and FL significantly correlate, they do have a different impact on the order of acquisition of word-initial consonants. When the impact of IF is partialed out, FL still has a significant correlation with acquisition order. The reverse is not true, suggesting that the acquisition of word-initial consonants is mainly influenced by their discriminating function.

Exploring and Explaining the Effects of Being Inspected.

This study looks into the effects of school inspection in the context of Flemish education. Respondents in five primary case schools were interviewed before inspection, immediately after inspection and four months later (totalling 45 interviews with 15 respondents). Our results indicate that the inspection incites reflection amongst school staff on the quality of their education before the inspection takes place, but the inspection itself does not provide substantial new insights in the schools’ strengths or weaknesses. The inspection judgement strongly affects the response of school towards the inspection. The case schools with a positive inspection report take practically no concrete action for improvement in the four months after inspection, while a more active response is seen in a school with a less favourable inspection report. The article also discusses the impact of some of the particularities of the Flemish education context on the effects of inspection.

Variation in the conduct and the quality of self‐evaluations: a multi‐level path analysis

While self‐evaluation leads to valuable results in some schools, it appears that in other schools this is true only to a lesser extent or not at all. This raises the question of how differences in the results of self‐evaluations can be explained. This study looks at to what extent the results of self‐evaluation are determined by the way in which self‐evaluation is conducted, by characteristics relating to the general functioning of the school and by the support which schools enjoy. One thousand seven hundred and eighty‐six school principals and team members from 96 schools (primary and secondary) were surveyed by means of a written questionnaire. The data collected were then analysed using multi‐level structural equation modelling. The results provide strong empirical evidence that “attitude with regard to self‐evaluation”, “self‐evaluation as a policy action” and “self‐evaluation as an act of research” are powerful predictors of the quality of self‐evaluations.

Infrequent word classes in the speech of two- to seven-year-old children with cochlear implants and their normally hearing peers: a longitudinal study of adjective use.

OBJECTIVE Studies investigating language skills of children after cochlear implantation usually use global language proficiency scores and rarely tackle the acquisition of specific language phenomena (word classes, grammatical constructions, etc.). Furthermore, research is largely restricted to frequent word classes (nouns, verbs). The present study targets the acquisition of adjectives (e.g. big, intelligent) by children implanted before their second birthday. Adjectives constitute a relatively infrequent, but functionally important word class and were shown to be good indicators of language delays and impairments. METHOD Nine cochlear-implanted (CI) children and 60 age-matched normally hearing (NH) controls participated in the study. The CI children were followed longitudinally from ages 2 to 7; control data were collected in a cross-sectional manner (10 children per age group). Samples of childrens spontaneous interactions with their caregivers were transcribed and analyzed for adjective use (frequency, lexical diversity, complexity of syntactic constructions, and morphological correctness). RESULTS The performance of the CI subjects was not significantly different from that of NH peers on adjective frequency and lexical diversity. On these measures, both groups reached adult levels by age 3. However, the CI group had a significant delay in the acquisition of complex syntactic constructions. The NH subjects produced adjectives in adult-like grammatical constructions from age 3 onwards, whereas their CI peers lagged behind until age 5. The speech of the CI participants also featured morphological errors that are not characteristic of typical development (inflection of predicative adjectives). However, the overall error rate was low. CONCLUSIONS The findings suggest that CI children have particular difficulty with grammatical items (bound morphemes, copulas) that are less salient in the flow of speech than content words. Nevertheless, children implanted before their second birthday are able to catch up with their hearing peers by age 5, even in the use of relatively infrequent word classes.

Hearing impairment and vowel production : a comparison between normally hearing, hearing-aided and cochlear implanted Dutch Children

This study investigated the acoustic characteristics of the Belgian Standard Dutch vowels in children with hearing impairment and in children with normal hearing. In a balanced experimental design, the 12 vowels of Belgian Standard Dutch were recorded in three groups of children: a group of children with normal hearing, a group with a conventional hearing aid and a group with a cochlear implant. The formants, the surface area of the vowel space and the acoustic differentiation between the vowels were determined. The analyses revealed that many of the vowels in hearing-impaired children showed a reduction of the formant values. This reduction was particularly significant with respect to F2. The size of the vowel space was significantly smaller in the hearing-impaired children. Finally, a smaller acoustic differentiation between the vowels was observed in children with hearing impairment. The results show that even after 5 years of device use, the acoustic characteristics of the vowels in hearing-assisted children remain significantly different as compared to their NH peers.

A longitudinal study on boys’ and girls’ career aspirations and interest in technology

Background: More young people, boys and girls, are needed in technical studies and professions, as the relative number of students in technology-related studies has been decreasing in most industrialised countries. To overcome this decrease several countries implemented mandatory technology classes in the curriculum of secondary education. Purpose: This study has two goals: exploring the evolution of pupils’ interest during the year(s) they attend the mandatory technology classes and exploring determining characteristics for differences in boys’ and girls’ attitude change over time. Sample: This study focuses on data gathered in the first and second grade of the first cycle in general secondary education in the North region of Belgium, Flanders. In a first stage we selected a good representation of geographically spread schools (n = 20), from which over 1300 students participated. Design and methods: A longitudinal study with eight measurement occasions spread over the course of two years is presented in order to capture the evolution of students’ attitudes, making use of a multilevel growth model analysis. Results: The results show that students’ interest in technology decreases over time, although at the end of each grade interest is increasing again. Boys’ and girls’ interest in technology also evolves a little different in the first cycle of secondary education. For career aspirations we didn’t see any significant difference between boys and girls. Boys’ and girls’ aspirations decrease over time with a little increase by the end of the second grade. Students with a more technological curriculum also have more career aspirations in the field of technology than their peers with other curricula. Although students’ perceptions about technology as a subject for boys and girls are largely stable. Conclusions: The evolution of students’ attitude is far from linear, this strengthens us in the choice for a more complex analysis model and the choice for more measuring points than only at the beginning and the end when analysing students’ attitudes towards technology. With this research we found that students interest and aspirations in the field of technology are not stable and do change in the first cycle of secondary education. Overall, we can conclude that if the goal of technology education at school maintains to promote ‘a larger number of students in technological oriented studies and professions’, there is still much to do.
