It is argued that tasks with different structures yield different performances in terms of accuracy, fluency and complexity. The present study is thus an attempt to investigate the impact of task structure on second language task performance. Thirty two upper-intermediate Iranian learners of English performed two narrative tasks (Structured vs.…

The goal of this study is to investigate the impact of manipulating the cognitive complexity of three different types of oral tasks on interaction. The study first considers the concepts of task complexity and interaction and then examines the specific studies that have looked at the effects of increasing task complexity on conversational…

This study examines the reading performance of selected students at the Pre-College program of the Mahidol University International College (PC-MUIC) as they are required to attain a score of 520 in the TOEFL-ITP (or equivalent performance in IELTS) to enter MUIC. Specifically, this research aims to evaluate whether the reading skills that…

There has been criticism about STEM education not focusing enough on problem solving, especially in authentic real-world contexts which are most often associated to ill-structured domains. To improve education, it is essential that curricula bring students to high levels of cognitive development by exposing them to authentic problems.…

The need to address social and economic changes has focused greater attention on our public education system and the need to better equip students with the skills needed for a global society. This quantitative study was grounded in the principles of the constructivist learning theory. The purpose of this study was to determine whether the added…

This research investigated the impact of automated cognitive assistants, specifically, the Personalized Assistant that Learns (PAL), on situational awareness, efficiency and effectiveness of decision making in the brigade combat team. PAL was recently commissioned by Defense Advanced Research Projects Agency (DARPA) to enhance decision making with…

The synthetic function, which is a weighted average of the identity (the trivial linking function for forms that are known to be completely parallel) and a traditional equating method, has been proposed as an alternative for performing linking with very small samples (Kim, von Davier, & Haberman, 2006). The purpose of the present study was to…

Theories of self-regulated study assume that learners monitor item difficulty when making decisions about which items to select for study. To complement such theories, the authors propose an agenda-based regulation (ABR) model in which learners' study decisions are guided by an agenda that learners develop to prioritize items for study, given…

Virtual reality (VR) technology has demonstrated effectiveness in a variety of technical learning situations, yet little is known about its differential effects on learners with different levels of visual processing skill. This small-scale exploratory study tested VR through quasi-experimental methodology and a theoretical/conceptual framework…

We have designed, developed, and validated a 25-question Genetics Concept Assessment (GCA) to test achievement of nine broad learning goals in majors and nonmajors undergraduate genetics courses. Written in everyday language with minimal jargon, the GCA is intended for use as a pre- and posttest to measure student learning gains. The assessment…

In this paper, the author gives a review of the literature on complex multivariate distributions. Some new results on these distributions are also given. Finally, the author discusses the applications of the complex multivariate distributions in the area of the inference on multiple time series. (Author)

Learning mathematics has been recognized by many as important. It does not only develop students' ability to think in quantitative terms but can also enhance skills such as analytical and problem solving skills. However, to enable us to tell our students how important mathematics is we have to understand students' beliefs in learning mathematics…

In this paper the academic English reading proficiency of 578 Norwegian university students was quantitatively examined. Self-assessment items were used to measure reading proficiency in Norwegian and English and validated using an International English Language Testing System Academic Reading Module. The study found that about 30% of the…

No Child Left Behind (NCLB) legislation and public pressure to prepare students for the twenty-first century has put increasing demands on schools to improve student performance. This action research study examined the efforts of an elementary school principal and her third and fourth grade teachers to improve students' performance in math. The…

The relationship of reading performance to difficulty level of material was the focus of this study. Participants in the study were 83 fourth graders from four urban schools. Each student was administered passages at different levels of challenge (independent, instructional, frustration) based on word identification accuracy. Passages were scored…
