Background: This paper discusses a framework for analyzing the dependence on mathematical theory in test items, that is, a framework for discussing to what extent knowledge of mathematical theory is helpful for the student in solving the item. The framework can be applied to any test in which some knowledge of mathematical theory may be useful,…

The goal of this meta-analysis is to evaluate how instructional technology has impacted advanced second language (AL2) development. Although numerous metaanalyses have been conducted within the CALL literature over the past two decades, they primarily focus upon learning outcomes and related effect sizes. None focus on advanced learning per se.…

Despite an increased awareness of language learner performance in task-based instruction, little is known about how learners perceive and respond to different task factors. This study investigates the effects of task complexity and modality on (a) learners' perception of task difficulty, skill, and its balance, and on (b) learners' task…

Multimedia students' dependence on information from the outside world can have an impact on their ability to identify and locate information from multiple resources in learning environments and thereby affect the construction of mental models. Field dependence-independence has been used to assess the ability to extract essential information from…

This study replicated, with modifications, previous research of dyad reading using texts at various levels of difficulty (Morgan, 1997). The current project measured the effects of using above-grade-level texts on reading achievement and sought to determine the influences of dyad reading on both lead and assisted readers. Results indicate that…

The aim of the present study is to compare the writing products of English as a Foreign Language (EFL) university students using accuracy and grammatical complexity as measures. It also aims at examining the development of the morphological, syntactic, lexical, spelling, and punctuation errors committed by these learners when writing in English.…

Information seeking (IS) has become a critical activity in video-based environments. Up to now, the effects of support on information seeking (i.e., scaffolding) have seldom been assessed. The twofold aim of the current study was to (a) assess the effects of scaffolding on IS in videos and (b) determine the characteristics of the users' mental…

With the advent of computers in education, and the ample availability of online learning and practice environments, enormous amounts of data on learning become available. The purpose of this paper is to present a decade of experience with analyzing and improving an online practice environment for math, which has thus far recorded over a billion…

The research focuses on the development and validation of an integrated assessment instrument to assess students' analytical thinking skills and chemical literacy in chemical equilibrium. The research consists of 5 phases ie analysis, design, development, implementation, and evaluation. The research participants were 174 students of grade 12th…

This report is the third in a series considering career-readiness features within high school assessments. The goal of this study was to explore international comparisons by applying feature analysis to Korean assessment items. Twenty math test items from the Gyeonggi Province in South Korea along with performance data from roughly 4,000 Grade 12…

This study is part of a larger design study that iteratively improves a robotics programming curriculum as well as a computational thinking (CT) instrument. Its focus was majorly on CT assessment and particularly on an online CT instrument with logging functionality that can store a student's problem-solving process by recording interactions…

International research collaboration raises questions about how groups from different national and institutional contexts can work together for common ends. This paper uses issues that have arisen in carrying out the first stage of an international research project to discuss a framework designed to map different kinds of multi-national research…

Teaching sensitive and controversial issues (SCIs) is of growing interest in contemporary, increasingly heterogeneous societies. In democracies, different groups and institutions expect their values and worldviews to be conveyed at school. On one hand, there is the expectation that SCIs should be treated neutrally. On the other hand, there are…

A new variant of the iterative "data = fit + residual" data-analytical approach described by Mosteller and Tukey is proposed and implemented in the context of item response theory psychometric models. Posterior probabilities from a Bayesian mixture model of a Rasch item response theory model and an unscalable latent class are expressed…

43 typically-developed adults and 35 adults with ASD performed a cartoon faux pas test. Adults with ASD apparently over-detected faux pas despite good comprehension abilities, and were generally slower at responding. Signal detection analysis demonstrated that the ASD participants had significantly greater difficulty detecting whether a cartoon…
