SEEK Web tutor: fostering a critical stance while exploring the causes of volcanic eruption

We investigated the impact of a Web tutor on college students’ critical stance and learning while exploring Web pages on science. Critical stance is an aspect of self-regulated learning that emphasizes the need to evaluate the truth and relevance of information as the learner engages in systematic inquiry to answer challenging questions. The Web tutor is called SEEK, an acronym for Source, Evidence, Explanation, and Knowledge. The SEEK Tutor was designed to promote a critical stance through several facilities in a computer environment: spoken hints on a mock Google™ search page, on-line ratings on the reliability of particular Web sites, and a structured note-taking facility that prompted them to reflect on the quality of particular Web sites. We conducted two experiments that trained students how to take a critical stance and that tracked their behavior while exploring Web pages on plate tectonics to research the causes of the volcanic eruption of Mt. St. Helens. The SEEK Tutor did improve critical stance, as manifested in essays on the causes of the volcanic eruption, and did yield learning gains for some categories of information (compared with comparison conditions). However, many measures were unaffected by either the presence of the SEEK Tutor or by prior training on critical stance. We anticipate that robust improvements on critical stance and learning will require more training and/or some expert feedback and interactive scaffolding of critical stance in the context of specific examples. This work was conducted while Tenaha O’Reilly was a postdoctoral fellow at the University of Memphis.     

Teacher Educator Identity in a Culture of Iterative Teacher Education Program Design: A Collaborative Self-Study

Faculty in the School of Education have collaborated to re-envision teacher education at our university. A complex, dynamic, time-consuming and sometimes painstaking process, redesigning a teacher education program from a traditional approach (i.e. where courses focus primarily on theoretical principles of practice through textbooks and university-based classroom discussions) to a model of teacher education that embraces teaching, learning and leading with schools and in communities is challenging, yet exciting work. Little is known about teacher educators’ experiences as they either design or deliver collaborative field-based models of teacher education. In this article, we examine our experiences in the second implementation year of our redesigned teacher education program, Teaching, Learning, and Leading with Schools and Communities (TLLSC) and how these unique experiences inform our teacher educator identities. Through a collaborative self-study, we sought to make meaning of our transformation from a faculty delivering a traditional model to educators collectively implementing a field-based model, by analyzing the diverse perspectives of faculty at different entry points in the TLLSC development and implementation process. We found that our participation in an intensive field-based teacher preparation model challenged our notions of teacher educator identity. In a culture of iterative program design, this study documents the personal and professional shifts in identity required to accomplish this collaborative and dynamic change in approach to teacher education.     

Stride length: the impact on propulsion and bracing ground reaction force in overhand throwing

Propulsion and bracing ground reaction force (GRF) in overhand throwing are integral in propagating joint reaction kinetics and ball velocity, yet how stride length effects drive (hind) and stride (lead) leg GRF profiles remain unknown. Using a randomised crossover design, 19 pitchers (15 collegiate and 4 high school) were assigned to throw 2 simulated 80-pitch games at ±25% of their desired stride length. An integrated motion capture system with two force plates and radar gun tracked each throw. Vertical and anterior–posterior GRF was normalised then impulse was derived. Paired t-tests identified whether differences between conditions were significant. Late in single leg support, peak propulsion GRF was statistically greater for the drive leg with increased stride. Stride leg peak vertical GRF in braking occurred before acceleration with longer strides, but near ball release with shorter strides. Greater posterior shear GRF involving both legs demonstrated increased braking with longer strides. Conversely, decreased drive leg propulsion reduced both legs’ braking effects with shorter strides. Results suggest an interconnection between normalised stride length and GRF application in propulsion and bracing. This work has shown stride length to be an important kinematic factor affecting the magnitude and timing of external forces acting upon the body.     

The Use of Equivocal Messages in Responding to Corporate Challenges

A framework is constructed to examine communication professionals’ views regarding the use of equivocal and nonequivocal messages for managing initial statements about corporate challenges. As predicted, equivocal responses were viewed as more appropriate to use and linked to a positive corporate reputation when the crisis situation contained avoidance–avoidance goal conflicts, whereas nonequivocal responses were viewed as more appropriate and linked to a positive corporate reputation when the crisis situation did not contain avoidance–avoidance goal conflicts. Communication professionals also judged nonequivocal and equivocal messages to be appropriate and linked to a positive corporate reputation when they believed the specific message would satisfy the multiple goals of the crisis situation. Implications for public relations practice are discussed.     

Doctoral students’ experiences of nondisclosure with their dissertation chair

We examined doctoral students’ experiences of nondisclosure with their dissertation chairs. Using a hermeneutic phenomenology design, we analyzed two individual interviews of 10 doctoral students. We identified the following three themes: (a) the professional dynamics in the relationship, (b) the interpersonal and cultural dynamics in the relationship, and (c) prioritization of completing the dissertation. Implications for doctoral students and dissertation chairs are discussed.     

Should Faculty Rank Be Included as a Predictor Variable in Studies of Gender Equity in University Faculty Salaries?

Many different approaches, almost all of which use some form of regression, have been used to study the issue of gender equity in university faculty salaries. One major point of contention in ail of these approaches is whether faculty rank, which is university conferred, should be included as a predictor variable. Two illustrations are presented to demonstrate how omitting faculty rank as a predictor variable from gender equity studies of university faculty salaries can lead to incorrect conclusions concerning gender discrimination. The first illustration uses hypothetical data constructed so that there is no difference in salary due to gender. However, when faculty rank is not included as a predictor variable in the regression model, there is a significant difference in salary due to gender. The second illustration uses actual data from a study of gender equity in pay at Bowling Green State University. This data set is used to construct a new data set that is totally free of gender bias. When a regression model omitting faculty rank is fit to this gender bias-free data, again a significant difference in salary due to gender is present. Therefore, it is recommended that faculty rank be included as a predictor variable in any model used to study gender equity relating to salary.     

Examining workload models in online and blended teaching

Over the past decade, most Australian universities have moved increasingly towards “blended” and online course delivery for both undergraduate and graduate programs. In almost all cases, elements of online teaching are part of routine teaching loads. Yet detailed and accurate workload data associated with “e‐teaching” are not readily available. A search of the international literature indicated that there is limited rigorous literature and research that points to the actual effects on workload in online and blended higher education teaching environments. This paper reports on a research project in four Australian universities, and the perceptions of a representative group of staff who perceived that e‐teaching had increased their “teaching time” workload, and that Workload Allocation Models (WAMs) did not take account of contemporary teaching modalities.     

Parent involvement and views of school success: The role of parents' Latino and White American cultural orientations

We examined ethnicity and cultural orientation as predictors of parents' views of and involvement in children's education, using data gathered from the Latino (n = 74) and non‐Latino (17 White and 13 ethnic minority) parents of children in an elementary school's dual‐language program. Parents completed a questionnaire that assessed Latino and White American cultural orientations, importance of children's academic and social success, and self‐ and significant other involvement in children's education. Results indicated that Latino (and other ethnic minority) parents valued academic and social success equally and more strongly than did Whites and that Whites valued social success more strongly than academic success. Latinos also reported greater involvement of significant others. These differences were largely accounted for by cultural orientations. Educational practices that take into account differences in cultural orientations and the involvement of significant others thus seem more likely to improve academic outcomes than do efforts intended to promote the valuing of education. © 2010 Wiley Periodicals, Inc.     

Estimating the Efficiency of Therapy Groups in a College Counseling Center

College counseling centers are facing rapidly increasing demands for services and are tasked to find efficient ways of providing adequate services while managing limited space. The use of therapy groups has been proposed as a method of managing demand. This brief report examines the clinical time savings of a traditional group therapy program in a college counseling center. The savings were mixed from semester to semester, ranging from 5 individual therapy spots lost to 10 individual therapy spots gained depending on the estimation. Considerations are offered for the use of therapy groups to manage clinical demand based on this report.     

Fathers’ and mothers’ home learning environments and children’s early academic outcomes

The home learning environment (HLE) that children experience early on is highly predictive of their later academic competencies; however, the bulk of this work is operationalized from mothers’ perspectives. This study investigates the HLE provided by both mothers and fathers to their preschoolers (n = 767), with consideration for how parents’ practices relate to one another as well as how these practices predict children’s early academic outcomes. Using an SEM framework, results indicate that while, overall, mothers provide HLE activities more frequently than fathers do, both mothers (β = .18, p < .05) and fathers (β = .22, p < .05) make unique contributions to their preschooler’s early academic skills, but only for families where mother has less than a bachelor’s degree. For families where mother has a bachelor’s degree or higher, the effect of father’s HLE practices is not a significant predictor of children’s academics when considering mother’s HLE. For all families, fathers are providing a variety of HLE activities to their young children; and, although these may occur less frequently than mothers’ practices, they are particularly important for the academic development of children whose mothers have less than a bachelor’s degree. Practical implications are discussed.
