This study examines the interaction behaviors and metacognitive behaviors of graduate students in the online portion of a flipped classroom. For their time outside the face to face classroom, students were given the choice of two online methods for their interactions--synchronous verbal discussions and asynchronous written discussions. Students…

The study explored the effect of cooperative learning on Grade 12 learners' performance in projectile motions. A quasi-experimental research design with non-equivalent control group was used. Two schools were purposively selected from Maleboho Central circuit in South Africa based on their performance in Physical Sciences Grade 12 results of 2011.…

Introduction: This article examines regulatory behaviors and physiological stress reactivity among 6-15 month-old infants with moderate to heavy prenatal alcohol exposure (PAE), a group at very high risk for fetal alcohol spectrum disorders and self-regulation impairments, compared to low risk infants with no/low exposure. Participants: Eighteen…

A case study presented here is an investigation into whether time of day for instruction has an effect on students' academic achievement in Mathematics, Science, Biology and English at school certificate level by focusing on the grades candidates obtained after sitting for national examinations. The focus is primarily on 33 randomly selected…

This study examined the perceptions of 6th grade middle school students regarding physics and physics-related careers. The overarching goal of this work was to understand similarities and differences between girls' and boys' perceptions surrounding physics and physics-related careers as part of a long-term effort to increase female interest and…

This study aimed at investigating the preferred refusal strategies in Persian. 3047 refusals collected by 108 field workers as well as 376 refusals collected through face to face interviews were analyzed and classified according to the descriptions proposed by Liao (1994) and Liao and Bresnahan (1996). The frequencies of the resulting direct and…

As item response theory has been more widely applied, investigating the fit of a parametric model becomes an important part of the measurement process. There is a lack of promising solutions to the detection of model misfit in IRT. Douglas and Cohen introduced a general nonparametric approach, RISE (Root Integrated Squared Error), for detecting…

Most methods for fitting cognitive diagnosis models to educational test data and assigning examinees to proficiency classes require the Q-matrix that associates each item in a test with the cognitive skills (attributes) needed to answer it correctly. In most cases, the Q-matrix is not known but is constructed from the (fallible) judgments of…

Testing strategies can either have a very positive or negative effect on the learning process. The aim of this study was to examine the degree of consistency in evaluating the practicality and logic of questions from a medical school pathophysiology test, between students and family medicine doctors. The study engaged 77 family medicine doctors…

Purpose: The purpose of this paper is to study Bayesian dependency modelling (BDM) to validate the model of educational experiences and the student-customer orientation questionnaire (SCOQ), and to identify the categories of educatonal experience in which students expect a higher educational institutions (HEI) to be student-customer oriented.…

Educational and political leaders across the nation seek to create a more educated population in order to compete in a global technology-oriented society and to increase earning potential of workers. Colleges and universities are currently seeking ways to increase persistence and achievement in order to produce more college graduates. Georgia's…

The focus of this study was to answer the following overarching question: How does a Twitter discussion format compare to a Facebook discussion format in terms of promoting collaborative argumentative discourse? Data analysis focused on the difference in amount of arguments, counter-arguments, reasons, and elaborations generated by participants…

Purpose/Objectives: In 2010, the Healthy, Hunger-Free Kids Act updated the nutrition standards for the National School Lunch Program (NSLP). The improved standards impact children who participate in the NSLP, but not the children who are bringing a packed lunch from home. Recent research suggests packed lunches are lower in nutritional quality…

Linear factor analysis models used to examine constructs underlying the responses are not very suitable for dichotomous or polytomous response formats. The associated problems cannot be eliminated by polychoric or tetrachoric correlations in place of the Pearson correlation. Therefore, we considered parameters obtained from the NOHARM and FACTOR…

This study analyses and compares the use of Web 2.0 tools by students in both learning and leisure contexts. Data were collected based on a questionnaire applied to 234 students from the University of Aveiro (Portugal) and the results were analysed by using descriptive analysis, paired samples t-tests, cluster analyses and Kruskal-Wallis tests.…
