Elementary Statistics with Minitab

Computer packages are available which can take much of the tedium out of the computational aspects of statistics and, we hope, thereby improve comprehension of the concepts. This article describes how the software package Minitab was incorporated into two elementary statistics courses, one at Kingston Polytechnic in England, the other at the University of North Carolina at Charlotte in the United States.     

Developing prospective elementary teachers’ abilities to identify evidence of student mathematical achievement

This study investigated the effects of a classroom intervention on prospective elementary teachers’ ability to evaluate evidence of student achievement of mathematical learning goals. The intervention was informed by a framework for teacher education which aims to provide prospective teachers (PTs) with the skills needed to systematically learn from their own teaching practice. Prospective teachers (N = 160) participated in an intervention aimed at addressing their misconceptions about evidence of student learning. Results revealed that after the intervention, PTs were less likely to consider teacher behaviors to be evidence of student learning and more likely to discount student responses that were irrelevant to a specified learning goal. However, PTs were still likely to take procedural fluency as evidence of conceptual understanding and may have become overly skeptical of student understanding. Implications of the study suggest new ways of developing prospective teachers’ ability to systematically study and improve their teaching.     

Improving the Human Condition: Leadership for Justice-Oriented Service-Learning

The Banneker History Project (BHP) reconstructed the history of the Benjamin Banneker School, which operated as a segregated school for African Americans from 1915 to 1951. It was a project in social justice education with community service as its base. Here, the authors provide an insider perspective of group dynamics among core leaders for the BHP. Building relationships, working for social justice, and confronting racism are key themes for the group. Leaders recall moments of discomfort, particularly related to issues of race and racism, and describe ways they worked through them. Based on their wisdom of practice, authors offer suggestions for those who might do similar work.     

Academic Factors Related to Student Achievement in a Capstone Food Chemistry Course

The 1st step in successfully intervening with students who may fail a course is to identify them as early as possible in the semester. The objective of this study was to create a model to predict student performance in FDSC 4304, the required capstone Food Chemistry class, using academic performance in prerequisite courses as potential predictors. We analyzed data for 116 undergraduates who completed Food Chemistry (FDSC 4304) between 2008 and 2015. Data included semester of enrollment and grade earned in FDSC 4304; transfer status; grades in prerequisite classes in science, math, and statistics courses and an introductory Food Science course, FDSC 1103; and the students’ university GPA at the time of enrollment in FDSC 4304. Cumulative GPA had the strongest significant (P < 0.001) positive correlation with FDSC 4304 grade (r = 0.64), followed by grade in statistics GPA (r = 0.52), FDSC 1103 grade (r = 0.45), pre‐requisite chemistry GPA (r = 0.44), and biology GPA (r = 0.42). When using partial correlations to control for cumulative GPA, only grades in FDSC 1103 (completed by 62.9% of students) were significantly correlated with grades in FDSC 4304. Linear regression indicated cumulative GPA and FDSC 1103 grades explained 35.5% of the variance in FDSC 4304 grades. When cumulative GPA (available for 91.6% of students) alone was regressed on FDSC 4304, it explained 40.6% of the variance for the larger group. Lower cumulative GPAs and FDSC 1103 grades are suggestive but not determinative of potential student struggles in FDSC 4304. Instructors should use cumulative GPAs and introductory food science course grades (either alone or in combination) with actual early course performance measures to identify students in need of additional help.     

Crafting the local: the lived experience of craft production in the Northern Isles of Scotland

ABSTRACT

National creative and cultural industries policy agendas tend to focus on the economic impact of the sector often favouring scalable digital activities based in global clusters, which underpin notions of growth. There has, however, been a re-emergence of craft, which may not be scalable in the same way, into public debate, with benefits linked to educational, cultural and economic policy agendas. Accordingly, policymakers have begun to view craft as a stimulus to develop local and regional economies, skills and materials in relation to wider networks. Within this push towards craft-driven creative place making and economic growth, it has been argued that more sophisticated understandings of the “local” are needed that go beyond those which are inward and parochial. Based on AHRC-funded empirical research undertaken in the Northern Isles of Scotland with craft practitioners, this article attempts to provide evidence of the place-based nature of craft work highlighting both opportunities as well as constraints linked to contexts that are often referred to as remote and peripheral when contrasted with urban locations. We argue for future investigation into, what we term, fractal growth – growth and development that considers multiple dimensions – as being a valid and valuable outcome of creative practice, and which cannot be easily scaled.     

Assessment of Integration of Technology in Education: Countering the “No Significant Differences” Argument

Literature in the field of information technology in educations in full of references to “no significant differences” findings from studies on the efficacy of technology integration. These findings may be due factors such as flawed assessment procedures, widely varying definitions of technology integration, and research design problems. The current special issue focuses on the development and use of reliable and valid instruments and procedures to access technology integration. This editorial reviews the concepts of reliability and validity, and summarizes assessment methods presented in the articles in this special issue.     

Improving the Measurement of School Climate Using Item Response Theory

The U.S. government has become increasingly focused on school climate, as recently evidenced by its inclusion as an accountability indicator in the Every Student Succeeds Act. Yet, there remains considerable variability in both conceptualizing and measuring school climate. To better inform the research and practice related to school climate and its measurement, we leveraged item response theory (IRT), a commonly used psychometric approach for the design of achievement assessments, to create a parsimonious measure of school climate that operates across varying individual characteristics. Students (n = 69,513) in 111 secondary schools completed a school climate assessment focused on three domains of climate (i.e., safety, engagement, and environment), as defined by the U.S. Department of Education. Item and test characteristics were estimated using the mirt package in R using unidimensional IRT. Analyses revealed measurement difficulties that resulted in a greater ability to assess less favorable perspectives on school climate. Differential item functioning analyses indicated measurement differences based on student academic success. These findings support the development of a broad measure of school climate but also highlight the importance of work to ensure precision in measuring school climate, particularly when considering use as an accountability measure.
