Structured reflection breaks embedded in an online course – effects on learning experience,time on task and performance

The purpose of this article is to gain an insight into the effects of practicing short, frequent, and structured reflection breaks interspersed with the learning material in a computer-based course. To that end, the study sets up a standardized control trial with two groups of secondary school pupils. The study shows that while performance is not affected by these embedded “reflection rituals,” they significantly impact time on task and perceived learning. The study also suggests that the exposure to such built-in opportunities for reflection modifies the engagement with the content and fosters the claimed readiness for application of a similar reflective approach to learning in other occasions.     

Lexical decision and oral reading by poor and normal readers

The primary goal of this study was to compare a paper-and-pencil version of the lexical decision task, which can be administered groupwise, with reading aloud a differently ordered list of the same words and pseudowords. Participants were first and second graders (“normal readers”) and students from schools for children with learning difficulties. On the average, the latter “poor readers” scored at the same oral reading level as the normal readers, but were older. The correlation between both tasks appeared to be high and both tasks had comparable correlations with third variables, suggesting that performance is determined by the same processes. Because the lexical decision task showed little evidence for guessing, it may be an — even better — alternative for oral reading. No differences between participant groups were found that point to different reading strategies. Error analysis, however, indicates that the poor readers probably have a specific problem in the oral reading of pseudowords.     

Interactive Instruction to Prevent Attention Problems in Class

This article reports the development and implementation of a strategy designed to bring persistent attention problems in class (off-task behaviour) under the control of teachers and students. The strategy enables the teacher to recognise the demotivating meaning that a task situation can have for a student. By pinpointing this situation in short dialogues with the student, the teacher encourages the student to make his or her own task proposal with the intention of turning the task into a feasible challenge. The strategy was designed from a cognitive-motivational interpretation of attention problems, and it is given shape in four programs for elementary schools. The theoretical frame of reference, the characteristics of the strategy, and the implementation of the programs are set out. Furthermore, an evaluation study is reported. The results indicate that teachers using the strategy can deal more effectively with students who have task behaviour problems. The students' on-task behaviour in this study increased in units of time from 60–70%. This revised version was published online in July 2006 with corrections to the Cover Date.     

Travelogue of an Almohad Sherd: from Twelfth-Century al-Andalus to Fourteenth-Century Flanders*

Excavations in Sint-Lievens-Houtem (Flanders, Belgium), an important medieval pilgrimage village, uncovered a fourteenth-century refuse pit. This feature contained a fragment of a rare Andalusī moulded lustreware vessel, dating to the mid or second half of the twelfth century. The reconstruction of the vessel’s itinerary aids in understanding how an object travelled from Muslim Spain to Catholic Flanders and why it ended up under Sint-Lievens-Houtem’s marketplace, about two centuries after its production. Traditional explanations of Crusades or trade seem unlikely or do not account for the entire trajectory of the vessel. These narratives are therefore extended with the incorporation of the vessel in Sint-Lievens-Houtem’s church treasury. This biographical approach offers a valuable framework to interpret the increasing number of Islamic finds across Europe, the way by which they travelled north and the contexts in which they functioned.     

Computer-Mediated Communication Environments in Teacher Education: Computer Conferencing and the Supervision of Student Teachers

The use of computer conferencing environments with student teachers and their supervisors was implemented during teaching practice and evaluated for four teacher education programs. Computer conferencing can be contrasted with the more common supervision methods, such as face-to-face conferences between the student teacher and the cooperating teacher, or between a group of student teachers and their supervisor at the teacher education institute. In our evaluation, we focused on participants' opinions of computer conferencing and their participation, activities and educational outcomes. During their field experiences, student teachers used computer conferencing primarily to exchange emotional support when they recognised similar experiences among their peers. It was less used for reflecting on their teaching and exchanging pedagogical content knowledge, including instructional methods and designs, classroom management strategies, general and instructional theories, and aspects of the teaching profession. This finding led to the conclusion that more attention should be paid to the structure of student teachers' learning environment, because more coaching and instruction of student teachers in their systematic and reflective use of computer conferencing leads to more varied and extensive communication     

Innovation management for an industrial product

Successful innovation in industrial products can be carried out by means of a carefully planned innovation process. This paper describes such a process carried out in a company that faced heavy financial losses due to an obsolete product mix.The total process took about two years, during which a new industrial product was acquired, the organization was adapted, the market introduction was started, and financial resources from outside the company were successfully obtained.The innovation process can be divided in different steps: objective formulation, potential product search, licence search or product development, negotiation, and finally market introduction.The first two steps were carried out in order to direct product development and licence search efforts as effectively as possible. As a result potential product licences were traced, on which none or only little furtner product development was needed. All this was fairly simple and took only a few months.During the negotiation (the next step), a very strong internal promotion of the most promising potential product licence was carried out at all decision levels, whilst at the same time the acquisition of this product licence was negotiated. Altogether this period lasted more than one year.Finally, a licence for a new product was acquired, after which the market introduction was started, resulting in a multimillion guiders turnover within less than two years after the start of the innovation process.The success of this product innovation resulted from careful planning and management of the whole process by an innovation manager, in cooperation with a task force, and from the considerable effort spent on internal company promotion. At the same time, pulling the selected new product through problem areas, and turning it into a commercial success, was the most creative part of this product innovation process.     

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.     

Test Design and Speededness

A critical component of test speededness is the distribution of the test taker’s total time on the test. A simple set of constraints on the item parameters in the lognormal model for response times is derived that can be used to control the distribution when assembling a new test form. As the constraints are linear in the item parameters, they can easily be included in a mixed integer programming model for test assembly. The use of the constraints is demonstrated for the problems of assembling a new test form to be equally speeded as a reference form, test assembly in which the impact of a change in the content specifications on speededness is to be neutralized, and the assembly of test forms with a revised level of speededness.     

Automated Test‐Form Generation

In automated test assembly (ATA), the methodology of mixed‐integer programming is used to select test items from an item bank to meet the specifications for a desired test form and optimize its measurement accuracy. The same methodology can be used to automate the formatting of the set of selected items into the actual test form. Three different cases are discussed: (i) computerized test forms in which the items are presented on a screen one at a time and only their optimal order has to be determined; (ii) paper forms in which the items need to be ordered and paginated and the typical goal is to minimize paper use; and (iii) published test forms with the same requirements but a more sophisticated layout (e.g., double‐column print). For each case, a menu of possible test‐form specifications is identified, and it is shown how they can be modeled as linear constraints using 0–1 decision variables. The methodology is demonstrated using two empirical examples.     

Students’ Overuse of Linearity: An Exploration in Physics

In mathematics education, a vast amount of research has shown that students of different ages have a strong tendency to apply linear or proportional models anywhere, even in situations where they are not applicable. For example, in geometry it is known that many students believe that if the sides of a figure are doubled, the area is doubled too. However, also history of science provides several cases of thinkers who inadequately postulated linear relations to describe situations. This article focuses on secondary school students’ over-reliance on linearity in physics. Now and then, science educators report students’ tendency to assume and impose linear relations in physics, but—as far as we know—no substantial efforts were undertaken to study this phenomenon systematically. We conducted an empirical investigation aimed at identifying the competence of 8th- and 11th-graders—before and after being taught the relevant physical topics—to qualitatively grasp various situations in physics, as well as their tendency to quantify that qualitative insight linearly. The results provide an ambivalent picture of students’ overuse of linearity in physics: Although linear reasoning is sometimes used as a default strategy, even after instruction that addresses the relevant physical contents, this study also indicates that context is taken into account more often than is suggested by research on mathematical problem solving.
