Validating Automated Measures of Text Complexity

Automated text complexity measurement tools (also called readability metrics) have been proposed as a way to help teachers, textbook publishers, and assessment developers select texts that are closely aligned with the new, more demanding text complexity expectations specified in the Common Core State Standards. This article examines a critical element of the validity arguments presented in support of proposed metrics: the claim that criterion text complexity scores developed from students’ responses to reading comprehension test items are reflective of the difficulties actually experienced by students while reading. Evidence that fails to support this assertion is examined, and implications relative to the goal of obtaining valid, unbiased evidence about the measurement properties of proposed readability metrics are discussed.     

DNA microarray wet lab simulation brings genomics into the high school curriculum

We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula.     

A journal is a club: a new economic model for scholarly publishing

A new economic model for the analysis of scholarly publishing – journal publishing in particular – is proposed that draws on club theory. The standard approach builds on market failure in the private production (by research scholars) of a public good (new scholarly knowledge). In this model, publishing is communication, as the dissemination of information. But a club model views publishing differently: namely as group formation, where members form groups in order to confer externalities on each other, subject to congestion. A journal is a self-constituted group, endeavouring to create new knowledge. In this sense, a journal is a club. The knowledge club model of a journal seeks to balance the positive externalities of a shared resource (readers, citations, referees) against the negative externalities of crowding (decreased prospect of publishing in that journal). A new economic model of a journal as a knowledge club is elaborated. We suggest some consequences for the management of journals and financial models that might be developed to support them.     

The Engagement of New Library Professionals in Leadership

Using data collected via a Web survey instrument, this study examines the leadership engagement of new professionals in Canadian libraries and explores their interest in and willingness to take up leadership roles as well as the barriers and opportunities to leadership that they perceive to exist within the workplace.     

The role of service-learning in transforming teacher candidates' teaching of reading

Most reading methods courses taught in the United States do little to change student teachers' actual classroom instruction because new pedagogies are not practiced in a structured, supportive, closely supervised manner. This lack of practice results in failure to develop strong feelings of self-efficacy during university courses. Because literacy courses fail to help preservice teachers think differently about literacy development, beginning teachers continue to perpetuate decades old methods of teaching young children how to read and write. These ‘business as usual’ pedagogies are especially dangerous for at risk learners.This study compared two literacy courses for elementary teacher candidates taught by the same professor at the same university with variables held constant with one exception. Course One incorporated a service-learning component as an integral part of the instructional process. During Course Two, the teacher candidates taught sample lessons to their classmates. It was hypothesized that teacher candidates who practiced new pedagogies with children at a designated low performing, highly diverse elementary school (Course One—Service-learning) during a highly structured service-learning experience would develop more self-efficacy and, therefore, demonstrate greater implementation of the course content than those who role played their practice (Course Two—Practice with Peers).Results document that incorporating service-learning into a well developed literacy course dramatically increased the self-efficacy of the participants by the conclusion of the course. This, in turn, led to increased implementation of course content during the remainder of their student teaching experience.     

Launching Interdisciplinary Programs as College Signature Areas: An Example

Increasingly administrators are concerned with inspiring and supporting faculty members in the creation of interdisciplinary programs in response to research and funding shifts and public need. This article presents an initative undertaken at the University of Colorado Denver, demonstrating a method for identifying and launching a set of signature interdisciplinary programs for a diverse college environment that overcomes hesitancy and hindrances at the individual, departmental, and institutional levels.     

New peace,new teachers: Student teachers' perspectives of diversity and community relations in Northern Ireland

This paper reflects upon student teachers' conceptions of inter-community relations and the preparation they receive to address issues of diversity and mutual understanding. The study in Northern Ireland is set against a backdrop of political, social and educational change, where a shared, peaceful future appears possible. Student teachers at a Catholic institution and a predominantly Protestant institution indicated a willingness to engage with issues concerning diversity and inter-community relations, despite having a limited knowledge of the concepts. However they also demonstrated clear views about the relevance and value of the preparation they received. The findings are evaluated using multicultural theory.     

Empowering Fathers of Disadvantaged Preschoolers to Take a More Active Role in Preparing Their Children for Literacy Success at School

The purpose of this study was to evaluate the effects of a project designed to empower fathers to take a more active role in their child’s academic literacy development. The fathers were parents of children enrolled in Early Head Start or Head Start programs. Data sources included transcribed interviews with fathers, the facilitator’s journal, and field notes compiled by the researchers. Findings in three areas emerged from the data: the fathers became increasingly committed to the literacy development of their children; participants learned about and regularly engaged in a variety of emergent literacy activities with their children; and participants developed confidence in their roles as agents for change in their children’s lives.     

Four research findings that will change what we think about perinatal depression

Research by health psychologists is changing what we know about perinatal depression. In this guest editorial, the author examines depression in pregnant and breastfeeding women in light of this recent research and describes four major findings that are influencing how we think about depression in new mothers: inflammation has an etiologic role in depression, a relationship exists between sleep disturbances and depression, breastfeeding protects maternal mental health, and all effective treatments for depression are anti-inflammatory interventions.     

Facial feature tracking: a psychophysiological measure to assess exercise intensity?

The primary aim of this study was to determine whether facial feature tracking reliably measures changes in facial movement across varying exercise intensities. Fifteen cyclists completed three, incremental intensity, cycling trials to exhaustion while their faces were recorded with video cameras. Facial feature tracking was found to be a moderately reliable measure of facial movement during incremental intensity cycling (intra-class correlation coefficient = 0.65–0.68). Facial movement (whole face (WF), upper face (UF), lower face (LF) and head movement (HM)) increased with exercise intensity, from lactate threshold one (LT1) until attainment of maximal aerobic power (MAP) (WF 3464 ± 3364mm, P < 0.005; UF 1961 ± 1779mm, P = 0.002; LF 1608 ± 1404mm, P = 0.002; HM 849 ± 642mm, P < 0.001). UF movement was greater than LF movement at all exercise intensities (UF minus LF at: LT1, 1048 ± 383mm; LT2, 1208 ± 611mm; MAP, 1401 ± 712mm; P < 0.001). Significant medium to large non-linear relationships were found between facial movement and power output (r² = 0.24–0.31), HR (r² = 0.26–0.33), [La^?] (r² = 0.33–0.44) and RPE (r² = 0.38–0.45). The findings demonstrate the potential utility of facial feature tracking as a non-invasive, psychophysiological measure to potentially assess exercise intensity.
