Statistical investigations, a thread within the statistics strand of the mathematics and statistics learning area (Ministry of Education, 2007), are underpinned by the statistical enquiry cycle. As teachers introduce their students to the statistical enquiry cycle, they are supporting their students to become data detectives, posing and answering…

In confirmatory factor analysis quite similar models of measurement serve the detection of the difficulty factor and the factor due to the item-position effect. The item-position effect refers to the increasing dependency among the responses to successively presented items of a test whereas the difficulty factor is ascribed to the wide range of…

While learning interventions were traditionally classified as either objectivist or constructivist there has been an increasing tendency for practitioners to use elements of both paradigms in a consolidated fashion. This has meant a re-think of the two perspectives as diametrically opposite. A four-quadrant model, first proposed in this journal…

This report is based on an activity completed by 89 Grade 6 students carrying out a statistical investigation with a focus on posing an initial question given a context and then refining it for a chosen data set. Having reached a conclusion based on evidence from their data analysis, students were given additional information on the context and…

Higher education institutions are ever more interested in the development of tools that enable them to evaluate and manage the expectations of their students with the purpose of attracting and keeping them satisfied. This research compares what the faculty believes the students expect from a higher education institution with the expectations of…

Moodle and other web-based learning systems have become very popular in higher education. Their success will not be achieved if students fail to use such systems. The present study investigates university student's attitudes regarding the use of Moodle. Forty-seven students from a Moroccan university were involved in the study. The students…

The present study investigates empirical models of groupwork management in online collaborative learning environments, based on the data from 298 students (86 groups) in United States. Data revealed that, at the group level, groupwork management was positively associated with feedback and help seeking. Data further revealed that, at the individual…

Traditional multiple-choice concept inventories measure students' critical conceptual understanding and are designed to reveal students' naive or alternate ideas. The overall scores, however, give little information about the state of students' knowledge and the consistency of reasoning. This study investigates whether students have consistent…

The current study investigated attentional control through active inhibition of the identity of the distractor. Adapting a Stroop paradigm, the distractor word was presented in advance and made to disappear, followed by the presentation of a Stroop stimulus. Participants were instructed to inhibit the distractor in order to reduce its…

Endocrine disrupting chemicals (EDCs) such as Bisphenol A (BPA) and phthalates are ubiquitous in our environment and a growing body of research indicates that EDCs may adversely affect human development. Fetal development is particularly susceptible to EDC exposure, and prenatal care providers are being asked to educate women about the risks of…

The author sought to investigate the effects of inquiry-based science instruction on science achievement and interest in science of 5,120 adolescents from 85 schools in Qatar. Results of hierarchical linear modeling analyses revealed the substantial positive effects of science teaching and learning with a focus on model or applications and…

This research explores the professionalization of Library and Information Science (LIS) students who participated in a peer-tutoring service, "Research Rescue." Research Rescue was a collaboration of the Chapman Learning Commons and the School of Library, Archival and Information Studies (SLAIS) at the University of British Columbia. The…

The purpose of this study was to investigate the knowledge, skills, abilities and traits environmental engineers need. Two questions were asked: what skills are considered important, and where are they learned? Dreyfus and Dreyfus' novice-to-expert model, which describes a progressive, five-step process of skill development that occurs over time…

Objective: This paper examined the relative influence of clinical and organizational characteristics on the decision to place a child in out-of-home care at the conclusion of a child maltreatment investigation. It tested the hypothesis that extraneous factors, specifically, organizational characteristics, impact the decision to place a child in…

Since the American Revolution free public education has been a discussion of political debate. The purpose that such an institution should play in society is a debate fervently argued when the founding fathers wanted to build a republic based on meritocracy. The problem this study addresses is the undefined relationship between the goals of…
