Performance and acceptance when using tablets as a multiple document learning tool: do application and guidance matter?

This study addressed whether an application adapted to working with multiple documents implemented in an iPad Pro tablet would promote students’ multiple document comprehension and acceptance of tablets as a multiple document learning tool relative to controls who used a traditional application adapted to sequential reading of single documents. Results indicated that students using the multiple document reading application outperformed the control students in terms of comprehension and also worked more efficiently on the assigned multiple document task, but only if given explicit guidance in selecting, organizing, and integrating information by utilizing the functions of the application. Still, after task completion, the more effective and efficient students guided in using the functions of the multiple document reading application displayed much less acceptance of tablets as a multiple document learning tool than did the control students. We discuss possible explanations for this intriguing performance-acceptance paradox and suggest some avenues for future research in this area.

     

Sorting or mixing? Multi-track and single-track schools and social inequalities in a differentiated educational system

In the Dutch stratified secondary educational system, schools vary in how many tracks are offered. While the tendency in the Netherlands is for schools to become smaller, a relevant policy question is whether multi-track school settings promote equality of educational opportunity. Comparing single-track schools at the pre-university and pre-vocational levels with multi-track schools offering the same exams, and using relative geographical distance as an instrument of school choice, the analyses showed that single-track pre-university schools enhance the probability of obtaining a pre-university diploma without delay, but more strongly so for students from disadvantaged backgrounds (who have a lower chance of going to such schools). The single-track pre-vocational schools were associated with a lower likelihood of achieving a diploma at a level higher than pre-vocational education. Multi-track schools within a varied system will not automatically enhance equal opportunities, as middle-class children will also benefit from the additional options that multi-track schools provide.

Detecting Answer Copying Using Alternate Test Forms and Seat Locations in Small-Scale Examinations

Two types of answer-copying statistics for detecting copiers in small-scale examinations are proposed. One statistic identifies the "copier-source" pair, and the other in addition suggests who is copier and who is source. Both types of statistics can be used when the examination has alternate test forms. A simulation study shows that the statistics do not depend on the total-test score. Another simulation study compares the statistics with two known statistics, and shows that they have substantial power. The new statistics are applied to data from a small-scale examination  ( N = 230)  with two alternate test forms. Auxiliary information on the seat location of the examinees and the test scores of the examinees was used to determine whether or not examinees could be suspected.     

Motivation and performance within a collaborative computer-based modeling task: Relations between students’ achievement goal orientation,self-efficacy,cognitive processing,and achievement

Purpose of the present study was to test a conceptual model of relations among achievement goal orientation, self-efficacy, cognitive processing, and achievement of students working within a particular collaborative task context. The task involved a collaborative computer-based modeling task. In order to test the model, group measures of mastery-approach goal orientation, performance-avoidance goal orientation, self-efficacy, and achievement were employed. Students’ cognitive processing was assessed using an online log-file measure. As predicted, mastery-approach goal orientation had a significant positive effect on achievement, which was mediated through students’ use of deep processes. No significant relationships could be found between performance-avoidance goal orientation and surface processing and between surface processing and achievement. Results are discussed with respect to general theoretical implications and lead to suggestions for the design of appropriate scaffolds.     

Developing and validating a design for teacher portfolio assessment

Developing and using a design for teacher portfolio assessment is a complex process including several components: the domain to be assessed (the teacher competences), the content standards or criteria, the portfolio format, the completion of the format (by teachers) with content, and the scoring of the portfolios (by raters). For a portfolio assessment to be valid, these components should be systematically linked. Using a chain model of the assessment process two links were verified: the link between content standards and portfolio format, and the link between content standards and raters’ scoring. Eight experts evaluated an initial portfolio assessment design. They greatly supported the design, including the link between standards and format. Subsequently, using the format 18 teachers developed a portfolio. Six raters scored these portfolios according to eight content standards. Their scoring was substantially based on the content standards. Implications of the results and suggestions for research are discussed.     

Effects of Pointing Gestures on Memory for (In)Congruent Stimuli in Children and Young Adults

We investigated whether finger pointing toward picture locations can be used as an external cognitive control tool to guide attention and compensate for the immature cognitive control functions in children compared with young adults. Item and source memory performance was compared for picture‐location pairs that were either semantically congruent (e.g., a cloud presented at the upper half of the screen) or incongruent (e.g., a cloud presented at the lower part of the screen). Contrary to our expectations, pointing had an adverse effect on source memory compared to visual observation only, in both age groups. As expected, superior source memory performance was found for congruent compared to incongruent picture‐locations pairs in both age groups. These findings suggest that pointing toward pictures compared to only viewing may hamper memory, and that congruent picture locations are easier to remember than incongruent ones.     

What Makes Informal Mentorship in the Medical Realm Effective?

Informal mentoring is based on a natural match between a junior individual and a senior one who share mutual interests. It usually aids in the professional and personal development of both parties involved. We reviewed the literature regarding factors that make informal mentoring effective within the medical realm, by searching a major academic search engine, Web of Knowledge, for the term “informal mentor*”. Our main research questions concerned the factors that lead to a successful informal mentorship process. A salient finding arising is that the success of informal mentorships hinges on the communication skills of mentor and protégé, their level of commitment, and the chemistry between the partakers. Good informal mentorships impose requirements on both mentors and protégés and rest on shared expectations.     

Technology Readiness, Learning Goals, and eLearning: Searching for Synergy

More and more business schools are offering classes online or classes using a mix of face‐to‐face and online elements. In this article, we focus on how technology readiness and learning‐goal orientation influence students' preference toward these mixed classes. We conducted a large‐scale survey to determine whether students who are technology ready would place higher utility on enrolling in mixed classes and/or whether there exists a participation bias such that students with low learning‐goal orientation place higher utility on enrolling in mixed classes. We found that overall students who are more technology ready do place higher utility on enrolling in mixed classes, but that learning‐goal orientation does not influence this decision. We conclude with implications and recommendations for business schools that are interested in offering mixed classes.
