Although distance educators are adopting electronic portfolios (eportfolios) for purposes of assessment and collaboration, some researchers question their utility in these venues. In a setting where feelings of isolation and attrition are high, this study examined how eportfolios affect cognitive load and student perceptions of support. The study…

The effects of self-pacing versus system-pacing were examined in different versions of a computer-based learning environment (static pictures/animations). The role of cognitive style was also considered. While the variables investigated did not have a direct impact on either learning outcome or cognitive load, significant interaction effects were…

Introduction: This study addresses two major issues with respect to cooperative learning. The study aims at experimentally investigating the function of positive resource interdependence and individual accountability on academic performance of individuals in cooperative learning. Method: To achieve the purpose a two by two randomized post-test…

We report tests of hypotheses derived from a theory of supportive communication outcomes that maintains the effects of supportive messages are moderated by factors influencing the motivation and ability to process these messages. Participants in two studies completed a measure of cognitive complexity, which provided an assessment of processing…

Multivariate matching in Differential Item Functioning (DIF) analyses may contribute to understand the sources of DIF. In this context, detecting appropriate additional matching variables is a crucial issue. This present article argues that the variables which are correlated with communalities in item difficulties can be used as an additional…

Updating and extending the work of O'Leary-Kelly, Martocchio, and Frink (1994), with this meta-analysis on goal setting and group performance we show that specific difficult goals yield considerably higher group performance compared with nonspecific goals (d = 0.80 plus or minus 0.35, k = 23 effect sizes). Moderately difficult and easy goals were…

The need for some form of explicit grammar instruction is recognised in most current approaches to second language teaching. Since the usefulness of explicit instruction is at least to some extent dependent on the difficulty of the rules that are taught, an important question for teachers is whether their judgements of rule difficulty are…

The scripts of 288 television episodes were analysed to determine the extent to which vocabulary reoccurs in television programs from the same subgenres and unrelated television programs from different genres. Episodes from two programs from each of the following three subgenres of the American drama genre: medical, spy/action, and criminal…

The purpose of this study has been to examine the impacts of aesthetic design on learner experience in an e-assessment environment, specifically on cognitive load and task performance. Sixty-six postsecondary students were randomly assigned to one of two aesthetic design configurations of the e-assessment environment: (1) an environment with low…

To compare different scoring algorithms for Pick-N multiple correct answer multiple-choice (MC) exams regarding test reliability, student performance, total item discrimination and item difficulty. Data from six 3rd year medical students' end of term exams in internal medicine from 2005 to 2008 at Munich University were analysed (1,255 students,…

"Technology," the buzz word for the last ten to fifteen years in South Africa. Technology availability is quite often mistaken for technology adoption and use. Technology has been made available to almost all tertiary institutions and at least some public schools. However, in most tertiary institutions many professors still refuse to use…

Simulation games can play a critical role in enabling students to navigate the problem spaces of the past while simultaneously critiquing the models designers offer to represent those problem spaces. There is much to be gained through their use. This includes rich opportunities for students to engage the past as independent historians; to consider…

The research described in this report is a randomized controlled trial in which seventh- and eighth-grade students were randomly assigned to complete a set of 25 math questions delivered with either standard language or language that had undergone "linguistic modification" by the research team. The purpose of the study was to assess the…

The purpose of this case study was to describe, assess, and compare the cognitive level of instruction, course objectives, instructional strategies, assessments, and the transdisciplinary nature of two post-secondary degree programs in sustainability. Instructional strategies in these programs included such methods as class presentations, group…

Response to Intervention provides a continuum of instruction across intensity levels through multitiered intervention models. A lot of work to date has been devoted to how to configure tiers to ensure the appropriate increases in intensity. Much less work has been devoted to making adjustments "within" tiers to attempt to forestall the need for…
