Conceptual Issues in Response-Time Modeling

Two different traditions of response-time (RT) modeling are reviewed: the tradition of distinct models for RTs and responses, and the tradition of model integration in which RTs are incorporated in response models or the other way around. Several conceptual issues underlying both traditions are made explicit and analyzed for their consequences. We then propose a hierarchical modeling framework consistent with the first tradition but with the integration of their parameter structures as a second level of modeling. Two examples of the framework are presented. Also, a fundamental equation is derived which relates the RTs on test items to the speed of the test taker and the time intensity of the items. The equation serves as the core of the RT model in the framework. Finally, empirical applications of the framework demonstrating its practical value are reviewed.     

Conceptualizing, investigating, and enhancing adaptive expertise in elementary mathematics education

Some years ago, Hatano differentiated between routine and adaptive expertise and made a strong plea for the development and implementation of learning environments that aim at the latter type of expertise and not just the former. In this contribution we reflect on one aspect of adaptivity, namely the adaptive use of solution strategies in elementary school arithmetic. In the first part of this article we give some conceptual and methodological reflections on the adaptivity issue. More specifically, we critically review definitions and operationalisations of strategy adaptivity that only take into account task and subject characteristics and we argue for a concept and an approach that also involve the sociocultural context. The second part comprises some educational considerations with respect to the questions why, when, for whom, and how to strive for adaptive expertise in elementary mathematics education.     

The effects of portfolio-based advice on the development of self-directed learning skills in secondary vocational education

This experimental study was designed to investigate whether supervision meetings, in which students receive specific advice on how to use a development portfolio to monitor their progress and plan their future learning, helps them to develop self-directed learning skills and improve their learning in the domain. In the first year of a hairdressing program in vocational education, supervision meetings were used to provide students with either specific advice or not. Students in the advice group (n = 21) formulated better learning needs, selected more suitable learning tasks, completed more practical assignments, and acquired more certificates than students in the feedback-only group (n = 22). Interviews also showed that students in the advice group appreciated the supervision meeting more and perceived them as more effective than students in the feedback-only group. Guidelines are provided for the use of development portfolios and the organization of supervision meetings in on-demand vocational education.

Parental Age and Offspring Childhood Mental Health: A Multi-Cohort,Population-Based Investigation

To examine the contributions of maternal and paternal age on offspring externalizing and internalizing problems, this study analyzed problem behaviors at age 10–12 years from four Dutch population-based cohorts (N = 32,892) by a multiple informant design. Bayesian evidence synthesis was used to combine results across cohorts with 50% of the data analyzed for discovery and 50% for confirmation. There was evidence of a robust negative linear relation between parental age and externalizing problems as reported by parents. In teacher-reports, this relation was largely explained by parental socio-economic status. Parental age had limited to no association with internalizing problems. Thus, in this large population-based study, either a beneficial or no effect of advanced parenthood on child problem behavior was observed.     

A Case Study in the Measurement of Educational Efficiency in Open and Distance Learning

Open and distance learning (ODL) gives learners control of the time, place, and pace of learning, often being characterized as flexible learning. However, this flexibility goes hand‐in‐hand with procrastination and non‐completion. As a result, the efficiency of the educational process is of importance to ODL providers, government funding agencies, and learners themselves. Despite its importance, measuring efficiency in ODL is problematic. This article presents a case study in measuring educational efficiency using a method which reflects the special characteristics of ODL. The article concludes with a discussion of the wider applicability of the measurement method in the context of lifelong learning.     

Teaching historical contextualization: the construction of a reliable observation instrument

Since the 1970s, many observation instruments have been constructed to map teachers’ general pedagogic competencies. However, few of these instruments focus on teachers’ subject-specific competencies. This study presents the development of the Framework for Analyzing the Teaching of Historical Contextualization (FAT-HC). This high-inference observation instrument focuses on history teachers’ competency in promoting historical contextualization in classrooms. The results of the study demonstrate the instrument’s content validity. Generalizability studies were conducted to further assess the instrument’s dimensionality and reliability by decomposing the instrument’s variance. A large proportion of the variance was explained by differences between observed teachers, and a small proportion of the variance was explained by lessons and observers, demonstrating the instrument’s reliability. Furthermore, a decision study was conducted to determine the optimal number of observers and lessons needed for a reliable scoring design. The developed instrument could be used to gain greater insight into history teachers’ subject-specific competencies and to focus teacher professionalization on teachers’ specific needs.     

Denominational School Identity and the Formation of Personal Identity

Three important factors determine the institutional identity of denominational (Christian) schools: their interpretation of the religious truth claim, their conception of the nature of education, and their view of cultural differences as content of education. We investigate conceptually which of these interpretations of identity are consonant with a view of education as a place where the personal identity of students is constructed. We interpret personal identity in a narrative way, as a permanent process of reflexive construction where consistency over time is not seen as an ideal, given the plurality of postmodern culture.     

Improving the reading of bisyllabic words that involve context-sensitive spelling rules: focus on successes or on failures?

The effect of two training procedures on the improvement of reading accuracy in poor readers was examined in relation to their initial reading level. A randomized controlled trial was conducted with 60 poor readers. Poor readers were assigned to a control group that received no training, or one of two training conditions. One training concentrated on the words the children read correctly (successes), the other on the words they read incorrectly (failures). They repeatedly read bisyllabic Dutch words, half of the training words involving context-sensitive spelling rules (vowel degemination or consonant gemination). Some children repeatedly read their successes, others their failures. The training used a computerized flashcards format. The exposure duration of the words was varied to maintain the accuracy rate at a constant level. In general, children who received training improved their reading accuracy and reading speed of trained words, and reading accuracy of untrained words, more than the control group. Which training focus is superior, depends on the reading level of the child and the type of words used. For children with a low initial reading level, to improve reading accuracy of bisyllabic words that follow context-sensitive spelling rules, a training focus on failures was superior over a training focus on successes. For children with a high initial reading level, improvement of reading speed was largest in a training on successes. Evidently, the improvement of word reading skills depends both on the children’s level of reading competence and on the type of training.     

Multilevel design efficiency in educational effectiveness research

In educational effectiveness research, multilevel data analyses are often used because research units (most frequently, pupils or teachers) are studied that are nested in groups (schools and classes). This hierarchical data structure complicates designing the study because the structure has to be taken into account when approximating the accuracy of estimation and the power for statistical testing, which should be sufficient to reach meaningful conclusions. Accuracy and power, both referred to as efficiency, can be optimized by carefully choosing the number of units to sample at each of the levels, taking into account the available resources and costs of sampling at these levels. We complement the findings that are found in the literature with regard to designing multilevel studies and propose a simulation approach that can be used to help making study-specific decisions.     

Measuring teaching quality in several European countries

Teaching quality has been observed in large representative samples from Flanders (Belgium), Lower Saxony (Germany), the Slovak Republic, and The Netherlands. This study reveals that measures of “creating a safe and stimulating climate”, “clear and activating instruction”, and “teaching learning strategies” were reliable and fully or at least partially scalar equivalent across these countries. Flemish teachers score higher, on average, on measures related to creating a safe and stimulating learning climate than do teachers in Lower Saxony, the Slovak Republic, or The Netherlands. With regard to the provision of clear and activating instruction, no significant differences arose in average scores across the 4 countries. Dutch teachers scored significantly higher on teaching learning strategies than teachers in Flanders and Lower Saxony but did not differ significantly from teachers in the Slovak Republic. Flemish and Slovak teachers earned higher average scores on teaching learning strategies than teachers in Lower Saxony.
