Darwin's theory of evolution by means of natural selection, called evolution for short, is perceived as a unifying theme in biology, forming a major part of all biology syllabuses. It is reported that student acceptance of evolution associates with conceptual understandings of biological contents, nature of science, as well as motivations to…

Recent publications have drawn attention to the idea of utilizing prior information about the correlation structure to improve statistical power in cluster randomized experiments. Because power in cluster randomized designs is a function of many different parameters, it has been difficult for applied researchers to discern a simple rule explaining…

Given the long history of discussion of issues surrounding statistical testing and effect size indices and various attempts by the American Psychological Association and by the American Educational Research Association to encourage the reporting of effect size, most journals in education and psychology have witnessed an increase in effect size…

In this introduction we reflect on two key questions that initiated this special issue on qualitative inquiry: What can qualitative researchers do to regain their post-paradigm-wars cache? How do we avoid distracting "science wars" in the future? We suggest that the strong tendency to narrow the research methods accepted as…

The purposes of this study are to add to the existing knowledge base on research self-efficacy beliefs of faculty members and their influence on research productivity, and to inform higher education administrators about the relationship between research self-efficacy beliefs and research productivity. A theoretical framework of social cognitive…

Collaboration is an essential part of school reform. There is growing demand to increase student achievement and close achievement gaps between learning groups. School systems are moving toward the incorporation of standards for collaboration in teacher rating scales. However, these changing expectations for collaborative performance have yet to…

Empirical Bayes' (EB) estimation is a widely used procedure to calculate teacher value-added. It is primarily viewed as a way to make imprecise estimates more reliable. In this paper we review the theory of EB estimation and use simulated data to study its ability to properly rank teachers. We compare the performance of EB estimators with that of…

The present study aims to probe the relationship between study habits and test anxiety of higher secondary students. In this normative study survey method was employed. The population for the present study consisted of higher secondary students studying in Tirunelveli district. The investigator used the simple random sampling technique. The sample…

Cloud computing is dramatically shaping modern IT infrastructure. It virtualizes computing resources, provides elastic scalability, serves as a pay-as-you-use utility, simplifies the IT administrators' daily tasks, enhances the mobility and collaboration of data, and increases user productivity. We focus on providing generalized black-box…

Since 2001, information technology (IT) leadership has had to contend with a host of new federal and local regulatory mandates. The purpose of this quantitative study was to identify and assess the possible inefficiencies associated with efforts to comply with recent legislative IT mandates and to model the impact of these mandates on the…

A central goal of the education literature is to demonstrate that specific educational interventions--instructional interventions at the student or classroom level, structural interventions at the school level, or funding interventions at the school district level, for example--have a "treatment effect" on student achievement. This paper…

Many projects fail despite the use of evidence-based project management practices such as Performance Measurement Baseline (PMB), Earned Value Management (EVM) and Risk Management (RM). Although previous researchers have found that integrated project management techniques could be more valuable than the same techniques used by themselves, these…

The New Zealand education system is culturally diverse and is guided by the principles of the Treaty of Waitangi to produce equitable outcomes for Maori students. The reporting of national educational outcomes is broken down by ethnicity to monitor educational performance of different ethnic groups and to identify ethnic disparities. The Ministry…

Background: Calculus is a foundational course for STEM-intending students yet has been shown to dissuade students from pursuing STEM degrees. In this report, we examine factors related to students and instructors reporting a lack of time in class for students to understand difficult ideas and relate this to students' and instructors' perceptions…

Background: Teaching online is a different experience from that of teaching in a face-to-face setting. Knowledge and skills developed for teaching face-to-face classes are not adequate preparation for teaching online. It is even more challenging to teach science, technology, engineering and math (STEM) courses completely online because these…
