Introducing serious games with Wikis: empowering the teacher with simple technologies

Despite the continuous and abundant growth of the game market the uptake of games in education has been hampered by the general impression that games require complex technologies and that games are difficult to organise and to embed in education curriculums. This article explores to what extent a simple serious game scenario that can be easily adopted and adapted by individual teachers and that only uses a common, relatively simple technology can leverage the adoption of serious games. It discusses the design of such a game, Argument, based on a Wiki and its use in a six weeks trial by students of a Master of Learning Sciences Programme. The results indicate that, even though a Wiki has clear limitations, it is a useful instrument to build game alike educational activities, to gain experience with and as a first step to use (more) complex serious games.     

Asking for Help: A Relational Perspective on Help Seeking in the Workplace

In the context of the complexity of today’s organizations, help seeking behavior is considered as an important step to problem solving and learning in organizations. Yet, help seeking has received less attention in organizational literature. To increase the potential impact of help seeking on learning, it is essential to understand which mechanisms affect help seeking. The present study questioned whether the characteristics of the relationships that employees have in the workplace are related to help seeking behavior. This study draws on a social network perspective to investigate the employees’ relationships within their professional network. In particular, the role of accessibility, awareness of expertise, trust, and hierarchy in help seeking was explored. Results indicated that the perceptions of the help provider’s expertise, accessibility and trust were positively associated with the likelihood to seek help, frequency by which help is sought, and perceived quality of the help. Moreover, employees seem more likely to seek help upward from higher status individuals and less likely downward from lower status individuals. Employees perceived the help of higher status individuals as more useful and constructive. These results highlight the importance of investing in the strength of relationships, ensuring the accessibility of expertise and fostering a work environment, in which employees trust and respect each other. Furthermore, the results suggest valuable and promising avenues for future research and practice.     

Forbidden friends as forbidden fruit: parental supervision of friendships, contact with deviant peers, and adolescent delinquency

Spending leisure time with deviant peers may have strong influences on adolescents' delinquency. The current 3-wave multi-informant study examined how parental control and parental prohibition of friendships relate to these undesirable peer influences. To this end, annual questionnaires were administered to 497 Dutch youths (283 boys, mean age = 13 years at baseline), their best friends, and both parents. Cross-lagged panel analyses revealed strong longitudinal links from contacts with deviant peers to adolescent delinquency, but not vice versa. Parent-reported prohibition of friendships positively predicted contacts with deviant peers and indirectly predicted higher adolescent delinquency. Similar indirect effects were not found for parental control. The results suggest that forbidden friends may become "forbidden fruit," leading to unintended increases in adolescents' own delinquency.     

Improving word reading speed: individual differences interact with a training focus on successes or failures

The effect of two training procedures on the development of reading speed in poor readers is examined. One training concentrates on the words the children read correctly (successes), the other on the words they read incorrectly (failures). Children were either informed or not informed about the training focus. A randomized controlled trial was conducted with 79 poor readers. They repeatedly read regularly spelled Dutch consonant?Cvowel?Cconsonant words, some children their successes, others their failures. The training used a computerized flashcards format. The exposure duration of the words was varied to maintain an accuracy rate at a constant level. Reading speed improved and transferred to untrained, orthographically more complex words. These transfer effects were characterized by an Aptitude-Treatment Interaction. Poor readers with a low initial reading level improved most in the training focused on successes. For poor readers with a high initial reading level, however, it appeared to be more profitable to practice with their failures. Informing students about the focus of the training positively affected training: The exposure duration needed for children informed about the focus of the training decreased more than for children who were not informed. This study suggests that neither of the two interventions is superior to the other in general. Rather, the improvement of general reading speed in a transparent orthography is closely related to both the children??s initial reading level and the type of words they practice with: common and familiar words when training their successes and uncommon and less familiar words with training their failures.     

Constructing Rotating Item Pools for Constrained Adaptive Testing

Preventing items in adaptive testing from being over- or underexposed is one of the main problems in computerized adaptive testing. Though the problem of overexposed items can be solved using a probabilistic item-exposure control method, such methods are unable to deal with the problem of underexposed items. Using a system of rotating item pools, on the other hand, is a method that potentially solves both problems. In this method, a master pool is divided into (possibly overlapping) smaller item pools, which are required to have similar distributions of content and statistical attributes. These pools are rotated among the testing sites to realize desirable exposure rates for the items. A test assembly model, motivated by Gulliksen's matched random subtests method, was explored to help solve the problem of dividing a master pool into a set of smaller pools. Different methods to solve the model are proposed. An item pool from the Law School Admission Test was used to evaluate the performances of computerized adaptive tests from systems of rotating item pools constructed using these methods.     

Testing the Intervention Effect in Single-Case Experiments: A Monte Carlo Simulation Study

This article reports on a Monte Carlo simulation study, evaluating two approaches for testing the intervention effect in replicated randomized AB designs: two-level hierarchical linear modeling (HLM) and using the additive method to combine randomization test p values (RTcombiP). Four factors were manipulated: mean intervention effect, number of cases included in a study, number of measurement occasions for each case, and between-case variance. Under the simulated conditions, Type I error rate was under control at the nominal 5% level for both HLM and RTcombiP. Furthermore, for both procedures, a larger number of combined cases resulted in higher statistical power, with many realistic conditions reaching statistical power of 80% or higher. Smaller values for the between-case variance resulted in higher power for HLM. A larger number of data points resulted in higher power for RTcombiP.     

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.     

Can visual aids in representational illustrations help pupils to solve mathematical word problems more realistically?

We investigated the effect of two visual aids in representational illustrations on pupils’ realistic word problem solving. In part 1 of our study, 288 elementary school pupils received an individual paper-and-pencil task with seven problematic items (P-items) in which realistic considerations need to be made to come to an appropriate reaction. These items were presented together either with representational illustrations, representational illustrations in which an element was added to make the realistic modelling complexity more apparent, or representational illustrations in which this element was cued. In part 2, the pupils received the same P-items together with a realistic and a non-realistic answer option, with the request to choose the best answer. The findings show that there was no positive effect of the visual aids on the number of realistic reactions in part 1 and that when reviewing possible answers to P-items in part 2, there again was no positive effect.     

A Statistical Test for Detecting Answer Copying on Multiple-Choice Tests

A statistical test for the detection of answer copying on multiple-choice tests is presented. The test is based on the idea that the answers of examinees to test items may be the result of three possible processes: (1) knowing, (2) guessing, and (3) copying, but that examinees who do not have access to the answers of other examinees can arrive at their answers only through the first two processes. This assumption leads to a distribution for the number of matched incorrect alternatives between the examinee suspected of copying and the examinee believed to be the source that belongs to a family of "shifted binomials." Power functions for the tests for several sets of parameter values are analyzed. An extension of the test to include matched numbers of correct alternatives would lead to improper statistical hypotheses.
