The 5th International Conference on Educational Data Mining (EDM 2012) is held in picturesque Chania on the beautiful Crete island in Greece, under the auspices of the International Educational Data Mining Society (IEDMS). The EDM 2012 conference is a leading international forum for high quality research that mines large data sets of educational…

This study investigates a project-based learning (PBL) approach to teaching evolution to inform efforts in teacher preparation. Data analysis of a secondary biology educator teaching evolution through a PBL approach illuminated: (1) active student voice, which allowed students to reflect on their positioning on evolution and consider multiple…

We used the single-case study method to develop an in-depth profile of Yajaira's (pseudonym) instruction based on her epistemological beliefs and science education experiences. We selected the participant using criterion based, purposeful sampling. Data collection included semi-structured interviews, direct observations, and the collection of…

Being bullied is associated with a psycho-social maladjustment during childhood. One hitherto largely overlooked correlate is disrupted classroom concentration. Using data collected from 364 9-11-year-old children attending seven junior schools in the UK, we tested a model in which children's perceived safety in two contexts (classroom and…

The purpose of the study was to update previous meta-analytic findings on the effectiveness of using similarities and differences as an instructional strategy. The strategy includes facilitating student comparison, classification, use of analogies, and use of metaphors. Previously, Marzano, Pickering, and Pollock reported a mean effect size of…

Convexity-based measures of shape compactness provide an effective way to identify irregularities in congressional district boundaries. A low convexity coefficient may suggest that a district has been gerrymandered, or it may simply reflect irregularities in the corresponding state boundary. Furthermore, the distribution of population within a…

First-year physics laboratories are often driven by a mix of goals that includes the illustration or discovery of basic physics principles and a myriad of technical skills involving specific equipment, data analysis, and report writing. The sheer number of such goals seems guaranteed to produce cognitive overload, even when highly detailed…

This article explores the nature of the experiential data used in reflective learning, reflective practice and ipsative research in higher education. Much of what has been written about experiential learning has focused on the nature of the reflective process. By contrast, this article explores the nature of the experiential data that underpins…

The purpose of this study was to describe the sustainability of professional development, specifically the teacher utilization of the Science-in-CTE pedagogical model and science-enhanced agricultural education lessons in curricula one year following the Science-in-CTE pilot study. This quasiexperimental study included 41 teachers (15 treatment…

This investigation provides detailed descriptions of preservice secondary science teachers' technology-enhanced inquiry instruction and their developing TPACK. Prior to student teaching, 27 preservice teachers were introduced to general guidelines for integrating technology to support reform-based science instruction. This instruction was in…

The purpose of this study is to present students' experiences, interest in engineering, and personal narratives while participating in a robotics summer camp in a metropolitan city in Turkey. In this study, I used qualitative data collection methods such as interviews, field notes, and observations. I used the four principles of Engle and Conant…

This naturalistic inquiry explores the lived experience of five teachers through the first of a two-year professional development (PD) focused on environmental systems, outdoor education, pedagogical content knowledge, and building a community of practice. Qualitative data include participant interviews, participant journals, and researcher field…

As anyone who has taught or taken a statistics course knows, statistical calculations can be tedious and error-prone, with the details of a calculation sometimes distracting students from understanding the larger concepts. Traditional statistics courses typically use scientific calculators, which can relieve some of the tedium and errors but…

To evaluate the implications of deliberate practice when teaching test administration skills, novice, but trained, graduate student examiners administered intelligence tests to a convenience sample of volunteer school-age examinees assigned to a first test session. A second, different convenience sample of volunteer school-age examinees were…

This article presents an interview with David Rindskopf, a Distinguished Professor of Educational Psychology and Psychology at the City University of New York Graduate Center, where he has taught since 1979. His research and teaching are in the area of applied statistics, measurement, and research design. He is a fellow of the American Statistical…
