Computer-based assessment of Complex Problem Solving: concept, implementation, and application

Complex Problem Solving (CPS) skills are essential to successfully deal with environments that change dynamically and involve a large number of interconnected and partially unknown causal influences. The increasing importance of such skills in the 21st century requires appropriate assessment and intervention methods, which in turn rely on adequate item construction, delivery, and scoring. The lack of assessment tools, however, has slowed down research on and understanding of CPS. This paper first presents the MicroDYN framework for assessing CPS, which is based on linear structural equation systems with input and output variables and opaque relations among them. Second, a versatile assessment platform, the CBA Item Builder, which allows the authoring, delivery, and scoring of CPS tasks for scientific and educational purposes is introduced. Third, we demonstrate the potential of such a tool for research by reporting an experimental study illustrating the effect of domain specific content knowledge on performance in CPS tasks both on an overall performance and on a process level. The importance of accessible and versatile technical platforms not only for assessment and research but also for intervention and learning are discussed with a particular focus on educational contexts.     

Knowledge Construction in Wikipedia: A Systemic-Constructivist Analysis

We propose a systemic-constructivist perspective for analyzing knowledge construction. In contrast to theories that focus on individuals as actors, the systemic-constructivist approach emphasizes the relevance of social systems and regards the construction of knowledge as a self-referential process that takes place in social systems. We propose that it is the system that defines what is accepted as legitimate knowledge and thus shapes individuals’ behavior. We present this approach and its implications by providing a case study of knowledge construction in Wikipedia. We analyzed the article about the Fukushima Daiichi nuclear power plant shortly after the nuclear catastrophe unfolded. There was a flood of highly uncertain information circulating, which the social system Wikipedia had to deal with and make meaning of. We obtained a group of very diverse people who largely lacked specific background education on the topic but accomplished the collaborative creation of an article that was later considered by experts to be of high quality. By interpreting these occurrences as operations of a social system, we aim to extend the theoretical basis of the learning sciences with an approach that emphasizes systems and their structures instead of individuals or groups. We discuss how this perspective may contribute to understanding collaborative knowledge construction.     

Integrating self-regulation in whole-class reciprocal teaching: A moderator–mediator analysis of incremental effects on fifth graders’ reading comprehension

In this classroom intervention study, reciprocal teaching (RT) of reading strategies was combined with explicit instruction in self-regulated learning (SRL) to promote the reading comprehension of fifth-grade students (N = 306). Twelve intact classes were randomly assigned either to an RT + SRL condition or to an RT condition without explicit instruction in self-regulation. Three additional classes served as a no-treatment comparison group. Strategies instruction was delivered by trained assistants in conventional German language lessons. Students practiced the application of these strategies in small groups. Both at posttest and at maintenance (8 weeks after the intervention), students in the two intervention conditions (RT and RT + SRL) outperformed comparison students in measures of reading comprehension, strategy-related task performance, and self-efficacy for reading. Relative to RT students, students in the RT + SRL condition were better able to maintain training-induced performance gains over the follow-up interval. A moderated mediation analysis revealed that this difference in the sustainability of the two treatments was (a) mediated by the successful mastery of the learned strategies and (b) most evident among students with poor reading fluency skills.     

A path analytic test of the reading strategies mediation model: Relating cognitive competences and motivational influences to individual differences in fifth-grade students' reading comprehension

This study examined a theoretical model hypothesizing that reading strategies mediate the effects of intrinsic reading motivation, reading fluency, and vocabulary knowledge on reading comprehension. Using path analytic methods, we tested the direct and indirect effects specified in the hypothesized model in a sample of 1105 fifth-graders. In addition to standardized tests and questionnaires, we administered a performance test to assess students' proficiency in the application of three reading strategies. The overall fit of the model to the data was good. Both cognitive (fluency and vocabulary) and motivational (intrinsic reading motivation) variables had an indirect effect on reading comprehension through their influence on reading strategies. Reading strategies had a unique effect on reading comprehension and partially mediated the effects that cognitive and motivational variables had on fifth-graders' reading achievements.
