This paper reports the results of an experiment designed to investigate the effectiveness of different collaborative group formations (homogeneous vs. heterogeneous in terms of prior computer knowledge levels) for learning complex tasks in computer programming from the perspective of cognitive load theory. Web-based learning platform was used to…

This study adapted web-based exploratory tasks using WebQuests as a means of enabling students to understand and reflect on both the target and their own culture. Learners actively used various authentic resources selected to meet their linguistic and cognitive needs to complete the tasks. The aim of this study was to help Japanese university…

Schools use an array of strategies to match curricula and instruction to students' heterogeneous skills. Although generations of scholars have debated ''tracking'' and its consequences, the literature fails to account for diversity of school-level sorting practices. In this article, we draw on the work of Sørensen and others to articulate and…

The aim of this paper is to test the connections between the indicators used in the literature on social cohesion, which usually reflect "general" values or behaviours, and indicators specific to a particular space, namely the labour market. A key question is the stability of the social cohesion's indicators when moving from a societal…

This paper reports a small part of the findings of a larger study which cross-culturally explored and comparatively examined the dynamics of collaboration between Iranian and Malaysian homogeneous dyads during performing collaborative writing tasks. The findings related to the amount of code-switching as well as the amount of falling back on the…

Drawing upon the Search for Ideas in Associative Memory (SIAM) model as the theoretical framework, the impact of heterogeneity and topic relevance of visual stimuli on ideation performance was examined. Results from a laboratory experiment showed that visual stimuli increased productivity and diversity of idea generation, that relevance to the…

We have assembled a large corpus of student submissions to an automatic grading system, where the subject matter involves the translation of natural language sentences into propositional logic. Of the 2.3 million translation instances in the corpus, 286,000 (approximately 12%) are categorized as being in error. We want to understand the nature of…

The present study tests the effect of ability pairing in two instructional methods in L2 collaborative revision. Two continuous indices determine a pair: individual proficiency level, distance in proficiency between pair members (heterogeneity), and the interaction between both indices. Instructional methods tested are modelling and practising.…

The purpose of this study, which is a major name in the education of gifted Dr. Cho 's about gifted education is to put forward their views. Dr. Seokhee Cho is a Professor at the School of Education, St. John's University. She is currently conducting three research projects funded by US Department of Education: Project HOPE as a Principal…

Learning a more distributed representation of the input feature space is a powerful method to boost the performance of a given predictor. Often this is accomplished by partitioning the data into homogeneous groups by clustering so that separate models could be trained on each cluster. Intuitively each such predictor is a better representative of…

In this multicountry analysis, we generate a student-level measure of socioeconomic status (SES) "mixing" to understand the benefits or pitfalls of placing low-SES children with diverse peers. We conduct this analysis separately for equal and unequal countries that provide the same curriculum to all children regardless of ability level,…

The purpose of this study was to examine the effects of heterogeneous and homogeneous grouping on the mathematical achievement of students in third grade. Participants were 16 third graders in a self-contained classroom, assigned to either small homogeneous or heterogeneous group for math instruction for 7 weeks. Pretest-posttest scores and growth…

A study was conducted to quantify the effectiveness of concept maps in learning physics in engineering degrees. The following research question was posed: What was the difference in learning results from the use of concept maps to study a particular topic in an engineering course? The study design was quasi-experimental and used a post-test as a…

An achievement gap exists in mathematics between low-income African American male students and their European American counterparts. Although this problem has been approached using different interventions with minimal results, the impact of homogenous grouping is not well understood in spite of its use. As a result, this study was conducted to…

Little comparative research examines which community-based preschool intervention placements produce the best outcomes for which children with autism spectrum disorders. Autism-specific placements can provide intensive evidence-based care; however, inclusion settings provide interaction with typically developing peers, the importance of which is…
