Mastering the ability to construct and manipulate Lewis structures is an important first step along the journey to reaching representational competence. Lewis structures serve as a convenient organizational scheme that can help students to scaffold their chemical knowledge and help them to apply it to predict a variety of physical and chemical…

Multiple-choice (MC) items are commonly used in high-stake tests. Thus, each item of such tests should be meticulously constructed to increase the accuracy of decisions based on test results. Haladyna and his colleagues (2002) addressed the valid item-writing guidelines to construct high quality MC items in order to increase test reliability and…

This study examined the effects of prior domain knowledge and learning sequences on learning with concept mapping and hypertext. Participants either made a concept map in a first step and then read the hypertext's contents combined with concept mapping (high activating condition), or they read the hypertext's contents first and then made a concept…

Cloze tests have been the subject of numerous studies regarding their function and use in both first language and second language contexts (e.g., Jonz & Oller, 1994; Watanabe & Koyama, 2008). From a validity standpoint, one area of investigation has been the extent to which cloze tests measure reading ability beyond the sentence level.…

The objective structural practical examination (OSPE) is a timed examination that assesses topographical and/or applied knowledge of anatomy with the use of cadaveric resources and medical images. This study investigated whether elements of question design (provision of clinical context, type of visual resources used, gender context, and…

The purpose of this study was to investigate English language related difficulties experienced by 30 Turkish dual diploma students studying in an ELT (English Language Teaching) program established between a Turkish and an American university, and to see the effects of those difficulties on the students' adjustment process in the U.S.A. The data…

Perception of topic difficulty is a likely predictor of lecture capture video use, as student perception of difficulty has been shown to affect a variety of outcomes in academic settings. This study measured the relationship between perceived difficulty and the use of lecture capture technology in a second year biochemistry course while…

Tasks provide engaging ways to involve learners in meaningful, real-world activities with the foreign language (FL). Yet selecting classroom tasks suitable to learners' linguistic readiness is challenging, and task-based research is exploring the relationship between learners' overall abilities (e.g., reading, grammatical) and the complexity and…

In recent decades, there has been an increasing emphasis placed on college graduation rates and reducing attrition due to the social and economic benefits, at both the individual and national levels, proposed to accrue from a more highly educated population (Bureau of Labor Statistics, 2011). In the United States in particular, there is a concern…

This study investigated the development of representational competence among organic chemistry students by using 3D (concrete and virtual) models as aids for teaching students to translate between multiple 2D diagrams. In 2 experiments, students translated between different diagrams of molecules and received verbal feedback in 1 of the following 3…

The present study investigated the effects of providing subtitles and taking enotes on cognitive load and performance. A total of 73 English-as-a-Foreign-Language (EFL) undergraduates learned brain anatomy and cognitive functions through multimedia programs. We used a 2 (subtitle/no) x 2 (taking enotes/no) factorial design to test the following:…

This study explores the relative contribution to EFL reading comprehension of the following individual-difference variables: prior knowledge, topic interest, linguistic proficiency, gender, reading motivation, and metacognitive awareness. It also investigates the relationship between the aforementioned individual differences and the role of text…

The career concern differences between undecided and decided college students (N = 223) are examined. Undecided college students (n = 83) reported lower career decision-making self-efficacy, higher incidences of negative career thoughts, and more career decision-making difficulties than their decided peers (n = 143). Results reveal that undecided…

"Item difficulty modelling" is a technique used for a number of purposes such as to support future item development, to explore validity in relation to the constructs that influence difficulty and to predict the difficulty of items. This research attempted to explore the factors influencing question difficulty in a general qualification…

In the school achievement and motivation literature of African American students, one major theme of the literature is a supposed inconsistency or discrepancy in African American students' value and expectations for their academic achievement and their actual levels of achievement. The discrepancy between Black students' achievement ideologies and…
