Improvement Science as a Promising Alternative to Barriers in Improving STEM Teacher Quality through Professional Development

STEM teaching occurs within national and state policy contexts that are constantly shifting in terms of standards and accountability due to the current and intense focus on students’ STEM outcomes. In the last two decades, federal legislation as well as common standards movements increasingly influence what and how STEM teachers instruct their students. Improvement science in education (ISE) has recently emerged as a new method of addressing many of the issues that impact teacher teaching and STEM teacher quality. ISE is a context-focused process improvement approach targeted at school improvement. This article explores three main barriers between STEM teacher professional development and student learning, and focuses on ISE as a promising alternative to current forms of STEM teacher professional development.     

Longer Fixation Times During Reading Are Correlated With Decreased Connectivity in Cognitive‐Control Brain Regions During Rest in Children

Dyslexia, or reading difficulty (RD), is characterized by slow, inaccurate reading and accompanied by deficit in executive functions (EF) and altered functional connectivity (FC) in the related networks (i.e., cingulo‐opercular). Individuals with RD also present with altered oculomotor gaze patterns that include longer fixation times. The researchers examined the relationship between fixation times and FC of neural circuits related to EF during rest in children with RD and typical readers. Nineteen children participated in a 10‐min resting‐state scan. FC analysis was performed with the anterior cingulate cortex (ACC), related to cognitive control, chosen as a seed. Fixation time during word reading was used as a covariate of interest. Results demonstrated that FC between the ACC and the left inferior frontal cortex pars triangularis and left inferior prefrontal cortex during rest were negatively correlated with fixation times during word reading. These exploratory results support the critical role for the cingulo‐opercular network, which is related to cognitive control, in the reading process, and likely also in reading impairment.     

Informal STEM: learning with robotics and game design in an urban context

Abstract

This mixed methods study examined how engagement in robotics and game design influenced students’ self-efficacy, STEM attitudes, and computational thinking (CT) skills. Predominantly African-American students engaged in engineering and computer science tasks during informal learning environments. Results revealed students’ self-efficacy scores on computer gaming increased significantly. Focus group data supported these findings, revealing that computer programing was challenging, but students enjoyed the tasks, added elements of culture in some cases, and valued the agency the tasks provided. Focal students were also able to make connections to STEM-related careers. Observational data demonstrated that focal students exhibited substantive CT during robotics and moderate CT during game design. Results support the idea that robotics and game design may be used to broaden underrepresented students’ participation in STEM.     

Summarizing Item Difficulty Variation with Parcel Scores

A new method for analyzing differential item functioning is proposed to investigate the relative strengths and weaknesses of multiple groups of examinees. Accordingly, the notion of a conditional measure of difference between two groups (Reference and Focal) is generalized to a conditional variance. The objective of this article is to present and illustrate a strategy for aggregating results across sets of similar items that exhibit item difficulty variation. Logically, this aggregation strategy is related to the idea of DIF amplification, but estimation is ultimately carried out in the framework of a confirmatory multidimensional Rasch model. Grade 4 data from the 2000 National Assessment of Educational Progress are used to illustrate the technique.     

The drugs don't work: expectations and the shaping of pharmacogenetics

This article examines one particular set of technologies arising from developments in human genetics, those aimed at improving the targeting, design and use of conventional small molecule drugs-pharmacogenetics. Much of the debate about the applications and consequences of pharmacogenetics has been highly speculative, since little or no working technology is yet on the market. This article provides a novel analysis of the development of pharmacogenetics, and the social and ethical issues it raises, based on the sociology of technological expectations. In particular, it outlines how two alternative visions for the development of the technology are being articulated and embedded in a range of heterogeneous discourses, artefacts, actor strategies and practices, including: competing scientific research agendas, experimental technologies, emerging industrial structures and new ethical discourses. Expectations of how pharmacogenetics might emerge in each of these arenas are actively shaping the trajectory of this nascent technology and its potential socio-economic consequences.     

Sustainability behaviors among college students: an application of the VBN theory

While Value-Belief-Norm (VBN) theory has been widely applied to various populations, it has seldom been tested on college students. This study extends VBN theory to examine what socio-psychological factors influence sustainability behaviors among university students. Undergraduate students are an interesting and novel population, as they are still forming their values and beliefs, and therefore may be more open to engage in sustainability efforts. This study assessed five sustainability behaviors: (a) support for political candidates who say they will strengthen environmental policies, (b) recycling, (c) electricity use, (d) food selection, and (e) transportation choices. Findings support the notion that one’s values matter in environmental decision-making, but that different values are associated with different behaviors. Those who adhere to biospheric and altruistic values were more likely to engage in a range of sustainability behaviors whereas those who adhere to egoistic values were less likely to engage in most behaviors. Those who adhere to traditional or openness to change values showed mixed results. We discuss the theoretical application, practical recommendations for behavior change campaigns, and offer suggestions for future research.     

Won't Fade Away: Intersections of Narrative and HIV and AIDS Activism in Jackson,Mississippi

This article demonstrates the therapeutic benefits of storytelling and testimony through qualitative interviews with HIV+ Black gay men in Jackson, Mississippi, in 2017. Sponsored by Project + Connect, a story preservation nonprofit based in New York, the research trip was inspired by a New York Times article claiming that 50% of all gay Black men in the South will contract HIV in their lifetimes. Analyzing the personal narratives of the study's participants against the political and historical contexts of racism and homophobia in the deep South, the researcher argues for the strengthening of the HIV/AIDS movement through storytelling, providing a pathway for theater teaching artists to use their skills to facilitate social change.

Sexual Content in Music and Its Relation to Sexual Attitudes and Behaviors among Consumers: A Meta-Analytic Review

While previous research has documented a relation between sexual content in music and the sexual attitudes and behaviors of consumers, to date, there are no meta-analytic reviews of the literature, making our meta-analysis the first in this area. Results from 26 studies indicated that sexual content in music had a significant effect on sexual attitudes and behaviors, with both music format and genre being significant contributors. Additionally, participant ethnicity, sex, age, location, and study design were found to be significant moderators. Theoretical implications are discussed, along with suggestions for future research.     

Predicting Engineering Student Attrition Risk Using a Probabilistic Neural Network and Comparing Results with a Backpropagation Neural Network and Logistic Regression

As the need for engineers continues to increase, a growing focus has been placed on recruiting students into the field of engineering and retaining the students who select engineering as their field of study. As a result of this concentration on student retention, numerous studies have been conducted to identify, understand, and confirm relationships between student attributes and attrition. Methods of prediction have also been evaluated and compared. Utilizing the attributes found in previous studies to have correlation with student attrition, this study considers the results of three different prediction methods—logistic regression, a multi-layer perceptron artificial neural network, and a probabilistic neural network (PNN)—to predict engineering student retention at a case study university. The purpose of this study was to introduce the PNN to the study of engineering student retention prediction and compare the results of the PNN to other commonly used methods in this field of study. The accuracy, sensitivity, specificity and overall results for each method are reported, compared, and discussed as the major contribution of this paper.
