Organic Chemistry is recognized as a course that presents many difficulties and conceptual challenges for students. To combat the high failure rates and poor student attitudes associated with this challenging course, we implemented a "flipped" model for the first-semester, large-enrollment, Organic Chemistry course. In this flipped…

In this article we propose several modeling choices to extend propensity score analysis to clustered data. We describe different possible model specifications for estimation of the propensity score: single-level model, fixed effects model, and two random effects models. We also consider both conditioning within clusters and conditioning across…

This study compared job stress levels of Texas agricultural science cooperating teachers and Texas agricultural science student teachers across a semester. The research objectives included describing secondary agricultural science cooperating teachers and student teachers perceptions of stressors, by time of semester (beginning, middle, and end),…

Three hundred and sixty-one students participating in university physical activity classes completed questionnaires assessing perceived health and self-regulated learning. In addition, 20 students (11 men; 9 women) were interviewed about their reasons for enrolling, participation and goals in the class. Results indicated the students endorsed…

Mobile learning is a cognitively demanding application and more frequently the ubiquitous nature of mobile computing means that mobile devices are used in cognitively demanding environments. This paper examines the nature of this use of mobile devices from a Learning, Usability and Cognitive Load Theory perspective. It suggests scenarios where…

Previous research has demonstrated that first-generation college students are less likely to persist to their sophomore year than non-first-generation students (Davis, 2010; Choy, 2001). The first six weeks has been identified as a critical time for adjustment and integration to college (Tinto, 1987; Astin, 1993; Woosley, 2003, 2009). Although…

This study examines the effect of small-group game play before and after a Number Sense Test (NST). Fifty-seven 7-year old children were assigned into two conditions: (a) NST-Game Play, in which students sat for the NST before game play; or (b) Game Play-NST, in which students experienced game play before sitting for the NST. Findings suggested…

A sample of 722 primary school students completed questionnaires from 3rd to 6th grade. Latent growth curve analyses revealed that the reading comprehension scores of…

Instead of the traditional set of slides, the visual aids of a presentation can now be graphic organisers (concept maps, knowledge maps, mind maps) on an infinite canvas. Constructing graphic organisers has a beneficial impact on learning, but this topic has not been studied in the context of giving a presentation. The present study examined this…

According to the 2008 U.S. Census, there are 15.5 million Asian Americans in the United States, and 17% are students enrolled in a university (Shea & Yeh, 2008). Asian American college students in higher education are oftentimes perceived as the "model minority" with high academic achievements and few mental and/or behavioral…

High and stable levels of aggression and the presence of aggressive behaviour in multiple settings according to different informants are risk factors for later problems. However, these two factors have not been investigated in early childhood. The present study investigates trajectories of parent-reported child aggression from 1.5 up to 6 years of…

Research was conducted to determine what impact school organization and classroom dynamics had on student achievement. Results from standardized benchmark tests found no significant differences in scores across all schools and content areas; yet, end of course standardized measures indicated that students in sites employing block scheduling…

This article analyzes the role that individual differences in children's cognitive, Spanish competence, and socio-emotional and behavioral skills play in predicting the concurrent and longitudinal acquisition of English among a large sample of ethnically diverse, low-income, Hispanic preschool children. Participants assessed at age 4 for language,…
