Team-based Introductory Research Experiences in Mathematics

Abstract

As part of Middle Tennessee State University’s (MTSU’s) initiative to improve retention of at-risk STEM majors, they recruit first-time, full-time freshman STEM majors with mathematics ACT scores of 19 to 23 to participate in MTSU’s “Mathematics as a FirstSTEP to Success in STEM” project (FirstSTEP). This article overviews MTSU’s FirstSTEP research approach and demonstrates that introductory, early research experiences can be successful for mathematics projects. At the end of their freshman year, mathematics students can develop a foundation to conduct mathematical research, increase depth of content knowledge, and build confidence in their technical abilities.     

The fluency principle: Why foreign accent strength negatively biases language attitudes

Two experiments tested the prediction that heavy foreign-accented speakers are evaluated more negatively than mild foreign-accented speakers because the former are perceived as more prototypical (i.e., representative) of their respective group and their speech disrupts listeners’ processing fluency (i.e., is more difficult to process). Participants listened to a mild or heavy Punjabi- (Study 1) or Mandarin-accented (Study 2) speaker. Compared to the mild-accented speaker, the heavy-accented speaker in both studies was attributed less status (but not solidarity), was perceived as more prototypical of their respective group, disrupted listeners’ processing fluency, and elicited a more negative affective reaction. The negative effects of accent strength on status were mediated by processing fluency and sequentially by processing fluency and affect, but not by prototypicality. Theoretical, methodological, and practical implications are discussed.     

Increasing Research Self-Efficacy Among Students in Professional Academic Programs

Gains in research self-efficacy for 60 Social Work and 75 Speech-Language Pathology students were compared. Our interest was to investigate whether students enrolled in both research and practice courses made greater gains in research self-efficacy over a semester, as compared to students enrolled in practice courses only. Findings indicated that Speech-Language Pathology students taking both research and practice courses showed the greatest gain. Examination of the Speech-Language Pathology curriculum suggested that when research courses were augmented with opportunities to apply research learning outside of class, greater gain in student confidence was achieved. We discuss implications for curricular development and interdisciplinary discourse on curriculum matters, and these implications reach beyond the two specific disciplines.     

Dyslexia policy and practice: cross‐professional and parental perspectives on the Northern Ireland context

This article considers policy and practice in relation to dyslexia provision in Northern Ireland since the 2002 Task Group Report. Using interviews with original and current stakeholders, this research, funded by SCoTENS (Standing Conference on Teacher Education, North and South), examined the extent to which recommendations have been met in the intervening years. Perspectives of interviewees indicated that while pockets of good practice have existed, this has been inconsistent. Despite the Department of Education (Northern Ireland) promoting and funding a significant and replicable model of teacher education and making efforts to monitor its efficacy, concerns remain regarding the optional nature of training, the maintenance of the discrepancy model of dyslexia identification, the need for early multi‐disciplinary identification, whole‐school policy development and post‐primary provision. In addition, stakeholders questioned the sustainability of funding and advocated enhanced transparency for parents, whose voices, it would appear, can still go unheard.     

Plasma MDA and antioxidant vitamins in diabetic retinopathy

Hyperglycemia and dyslipidemia in diabetes mellitus induce increased lipid peroxidation and peroxyl radical formation, an important mechanism in genesis of microangiopathy. We took up a study on oxidative stress, measured by plasma MDA and antioxidant vitamin status in type − 2 DM patients with and without retinopathy and compared them with a control non-diabetic group. Lipid peroxidation marker MDA was significantly elevated (p < 0.001) in both the diabetic groups whereas, serum vitamin E and vitamin C registered a significant fall (p<0.001) as compared to controls. Our correlation study revealed a significant positive association between plasma MDA with both fasting and 2hr post prandial plasma glucose (r=0.81, p < 0.001, r=0.92, p <0.001) suggesting the role of hyperglycemia in free radical production. Plasma MDA also depicted significant positive relation (p< 0.001) with all lipid parameters except serum HDLc pointing the role of dyslipidemia towards lipid peroxidation. Plasma MDA level was also found to be negatively correlated with both the vitamins (p<0.001, p<0.001) in the study group explaining their protective consumption in the oxidative process prevailing in diabetic retinopathy.     

The action research process as a means of helping student teachers understand and fulfil the complex role of the teacher

The Mid-Town elementary preservice cohort programme at OISE/UT has, for several years, had action research by student teachers as a major component. In this article, the authors outline the view of action research held by the faculty team and explain why they turned to action research as a strategy in teacher education. They detail how the action research requirement is implemented in the programme, and describe the effects of the action research process on the understandings, skills and behaviour of the preservice teachers. The findings suggest this is potentially a very valuable approach to teacher education, provided certain other conditions are fulfilled.     

Advance Contracting,Word-of-Mouth,and New-Product Success in Creative Industries: A Quantification for Books

The odds of success in creative industries (e.g., book, music, or movie) are often said to be particularly low. Furthermore, due to the nature of advance contracting between creator and producer, the standard approach to use sales as a success measure can be misleading from the producer's perspective. This article presents a novel approach to empirically identify producer success by incorporating the standard terms of contract between creator and producer into a parsimonious model of information diffusion (word-of-mouth) about new products. The model is applied to weekly sales data for a representative sample of novels. Estimation results indicate a success rate between 10% and 15% for this market.
