Abstract

The purpose of this study was to develop a regression equation to predict maximal oxygen uptake (VO₂max) based on nonexercise (N-EX) data. All participants (N= 100), ages 18–65 years, successfully completed a maximal graded exercise test (GXT) to assess VO₂max (M= 39.96 mL·kg ^-1· min ^-1 , SD = 9.54). The N-EX data collected just before the maximal GXT included the participant's age; gender; body mass index (BMI); perceived functional ability (PFA) to walk, jog, or run given distances; and current physical activity (PA-R) level. Multiple linear regression generated the following N-EX prediction equation (R = .93, SEE = 3.45 mL·kg ^-1· min ^-1 , %SEE= 8.62): VO₂max (mL·kg ^-1· min ^-1 ) = 48.0730 + (6.1779 x gender; women = 0, men = 1) – (0.2463 x age) – (0.6186 x BMI) + (0.7115 x PFA) + (0.6709 x PA-R). Cross validation using PRESS (predicted residual sum of squares) statistics revealed minimal shrinkage (R _p = .91 and SEE _p = 3.63 mL·kg ^-1· min ^-1 ); thus, this model should yield acceptable accuracy when applied to an independent sample of adults (ages 18–-65 years) with a similar cardiorespiratory fitness level. Based on standardized β-weights, the PFA variable (0.41) was the most effective at predicting VO₂max followed by age (-0.34), gender (0.33), BMI (-0.27), and PA-R (0.16). This study provides a N-EX regression model that yields relatively accurate results and is a convenient way to predict VO₂max in adult men and women.     

Techno Savvy: a Web 2.0 curriculum encouraging critical thinking

This paper reports results from a case study focused on understanding student practices regarding production-oriented problem-solving with digital media. Thirty-seven students participated in an elective curriculum called, “Techno Savvy,” a nine-week course focused on student exploration of global issues, and designed around Web 2.0 tools. Socio-constructivist theory provided the theoretical lens to write and study the curriculum. Complexity in student practices using digital media tools to determine critical thinking is highlighted. Data were analyzed for patterns observed in student practices, video, artifacts, oral, and written work. Results suggest that student interaction and practices afforded by tools and content within the curriculum encourage critical thinking. This study implies a need for further classroom research linking pedagogical approaches with digital media to critical thinking and achievement.     

Can a Summer Bridge Program Impact First-Year Persistence and Performance?: A Case Study of the New Start Summer Program

This longitudinal study assesses the impact of the University of Arizona’s New Start Summer Program (NSSP) on participants’ first year GPA and retention, controlling for incoming student characteristics. While programmatic participation significantly predicted first-year GPA and retention, this relationship became insignificant when controlling for first-year college experiences and student development. Programmatic efficacy is largely determined not only by how practitioners develop participants’ cognitive abilities, but also how effectively they connect them to social and academic support networks during their first year of college. Within this context, programmatic impact is likely indirect which poses a number of methodological and resource allocation issues for student affairs administrators and professionals. In addition, it highlights the need to assess the impact of summer bridge programs longitudinally while also having a demographically similar group of students who did not participate for comparison: Two areas generally absent from research on summer bridge program literature. Finally, the study was made possible because of a strong collaboration between the NSSP administrators and the research team, where the goals and needs of each group were supported by the other.     

Gaming the system: culture,process, and perspectives supporting a game and app design curriculum

Games and digital media experiences permeate the lives of youth. Researchers have argued the participatory attributes and cognitive benefits of gaming and media production for more than a decade, relying on socio-cultural theory to bolster their claims. Only recently have large-scale efforts ensued towards moving game play and design into formal schooling. Educators are beginning to recognize the instructional potential of games but are seeking ways to understand and effectively support them in learning environments. This paper offers a working example detailing the process of creating a high school curriculum focused on game and app design. Through the example, the author addresses the ‘why’ and ‘how’ to move forward with games in schools and argue the necessity of cultivating a participatory culture. The example concludes with assumptions from this experience and an invitation for scholars to critique and discuss the instance.     

Feedforward strategies in the first-year experience of online and distributed learning environments

Feedforward is an educational strategy focusing on providing students with prior exposure to, and prior practise with assessment in order to clarify expectations and standards. Current research into feedforward has yet to fully consider the specificity of online and distributed learning environments. We have developed a feedforward-based approach to teaching a large first year prerequisite course in screen history involving the modified and critical use of exemplars and assessment guidance in ways designed to stimulate self and peer assessment throughout the course. Our focus is the improvement of task compliance, quality and criteria in order to stimulate meaningful engagement with assessment and enhanced student performance in the unit.     

Amplitude envelope perception, phonology and prosodic sensitivity in children with developmental dyslexia

Here we explore relations between auditory perception of amplitude envelope structure, prosodic sensitivity, and phonological awareness in a sample of 56 typically-developing children and children with developmental dyslexia. We examine whether rise time sensitivity is linked to prosodic sensitivity, and whether prosodic sensitivity is linked to phonological awareness. Prosodic sensitivity was measured by two reiterant speech tasks modelled on Kitzen (2001). The children with developmental dyslexia were significantly impaired in the reiterant speech tasks and in the phonological awareness tasks (onset and rime awareness). There were significant predictive relations between basic auditory processing of amplitude envelope structure (in particular, rise time), prosodic sensitivity, phonological awareness, reading, and spelling. The auditory processing difficulties that characterise children with developmental dyslexia appear to impair their sensitivity to phrase-level prosodic cues such as metrical structure as well as to phonology, but in this study phonological and prosodic sensitivity made largely independent contributions to reading.     

Prior knowledge,reading skill,and text cohesion in the comprehension of science texts

This study examined how text features (i.e., cohesion) and individual differences (i.e., reading skill and prior knowledge) contribute to biology text comprehension. College students with low and high levels of biology knowledge read two biology texts, one of which was high in cohesion and the other low in cohesion. The two groups were similar in reading skill. Participants' text comprehension was assessed with open-ended comprehension questions that measure different levels of comprehension (i.e., text-based, local-bridging, global-bridging). Results indicated: (a) reading a high-cohesion text improved text-based comprehension; (b) overall comprehension was positively correlated with participants' prior knowledge, and (c) the degree to which participants benefited from reading a high-cohesion text depended on participants' reading skill, such that skilled participants gained more from high-cohesion text.     

“What Do You Say to Your Mother When Your Mother's Standing Beside You?” Birth and Adoptive Family Contributions to Adoptive Identity via Relational Identity and Relational–Relational Identity Gaps

Grounded in the communication theory of identity, the present study explores how adoptive identity—an individual's understanding of what it means to be an adopted person—is influenced by the relational layer of his or her adoptive and birth family relationships. Seven focus group interviews were conducted in which participants were prompted to engage in a dialog about their experiences as an adopted individual. Analyses revealed that adoptees' relational identity with both their adoptive and birth families contributed in meaningful ways to their adoptive identity, but these relationships at times come into conflict with one another and with the adoptees' personal layer of identity, generating relational–relational and personal–relational identity gaps.     

Integration Amidst Separation: Religion,Urban Education,and the First Amendment

In today’s urban schools, foreign-born children and children of immigrants are the fastest growing sector of the student population and as a result of this changing demographic, our schools are more ethnically, racially and religiously diverse than they have ever been (Suárez-Orozco et al. in Thriving and spirituality among youth: research perspectives and future possibilities. Wiley: Hoboken, NJ, 2012). For many students of immigrant families, their spiritual/religious identity is an important aspect of a healthy and integrated identity. While professional journals in education have focused on race, ethnicity and culture as important diversity variables, the extent to which students’ religion and spirituality influence their development and education has largely been a neglected topic (Woolley in Int J Child Spiritual 13:145–156, 2008). Thus, we highlight research in education, school counseling, and psychology that examines the legal and ethical implications of including religion and spirituality into urban educators’ work with students. We then explore the role that spirituality/religion plays in health, coping, and academic achievement for students, the importance of spirituality/religion within historically marginalized communities, students’ experiences as religious minorities, and religious discrimination in schools. Within each topic area, we outline practical considerations. Finally, we offer some guidelines for professional preparation programs and curriculum development in urban education.
