The purpose of this paper is to capture the pedagogical content knowledge (PCK) of university professors about quantum chemistry. More specifically, we aimed to identify and analyze relationships between specific PCK components, using an adapted version of the model of PCK of Magnusson "et al.". A sample of university professors (n = 6)…

Drawing on an ecological perspective, this paper reports on an investigation into the changes in one first-year college student's beliefs about English teaching and learning since his enrollment. These changes in beliefs are part of the empirical findings of a multiple-case study conducted in the Chinese EFL context. Semi-structured interviews,…

Over recent decades, educators have recognized the crucial importance of teaching environment and contextual factors in teaching and learning outcomes. Public and private schools are among those teaching contexts that have been in competition for teaching quality and effectiveness for many years. This study investigated the effectiveness of some…

Microarray is a high throughput technology to measure the gene expression. Analysis of microarray data brings many interesting and challenging problems. This thesis consists three studies related to microarray data. First, we propose a Bayesian model for microarray data and use Bayes Factors to identify differentially expressed genes. Second, we…

One of the challenges confronting teachers today is effectively using data to drive instructional decisions-making in their classrooms. The purpose of this study was to examine whether professional development and the use of coaches in the area of data-driven instruction impacts classroom instructional practices and how student achievement could…

In this study we contrasted the Category fluency and Letter fluency performance of 198 normal subjects, 57 Alzheimer's patients and 57 patients affected by traumatic brain injury (TBI). The aim was to check whether, besides the prevalence of Category fluency deficit often reported among Alzheimer's patients, the TBI group presented the opposite…

The use of qualitative analysis software has become extremely popular over the recent years; educational researchers now have a range of tools at their disposal, from the ubiquitous word processor to more specialized computer packages. This paper deals with the use of CAQDAS (computer-assisted qualitative data analysis software) in educational…

Accomplished throwers conserve angular momentum when distal joints of the throwing arm reach peak velocity at a later time than their proximal neighbors. The result is an increase in velocity of the most distal segment--the hand. Past research indicates that skill level varies by the number of joints experiencing distal timing lag (time to peak…

This study uses within-study comparisons to assess the relative importance of covariate choice, unreliability in the measurement of these covariates, and whether regression or various forms of propensity score analysis are used to analyze the outcome data. Two of the within-study comparisons are of the four-arm type, and many more are of the…

There has been a growing body of professional literature regarding the importance of school counselors behaving as leaders in schools.
