“Who are you callin' expert?”: Using student narratives to redefine expertise and advocacy lower track science

The purpose of this study was to construct an interpretation of lower track science students' notions of expertise in science teaching. Data were collected and transcribed from focus groups, teacher journals, classrooms events, and student artifacts. Students responded to focus group prompts over the course of a years regarding how and why they chose to learn science from their teachers based on affective attributes, advocacy/impedance, and identity. Results showed that lower track science students closely associate affective teacher attributes with effective teaching strategies. In addition, students identified advocacy or impedance in academic success based on personal experience rather than other more overt characteristics such as race or gender as a major determinant for their successful science learning. Implications for research and teacher education in diverse settings are discussed. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 48: 13–36, 2011

Learning in Stereo: The Relationship Between Spatial Ability and 3D Digital Anatomy Models

Three-dimensional (3D) digital anatomical models show potential to demonstrate complex anatomical relationships; however, the literature is inconsistent as to whether they are effective in improving the anatomy performance, particularly for students with low spatial visualization ability (Vz). This study investigated the educational effectiveness of a 3D stereoscopic model of the pelvis, and the relationship between learning with 3D models and Vz. It was hypothesized that participants learning with a 3D pelvis model would outperform participants learning with a two-dimensional (2D) visualization or cadaveric specimen on a spatial anatomy test, particularly when comparing those with low Vz. Participants (n = 64) were stratified into three experimental groups, who each attended a learning session with either a 3D stereoscopic model (n = 21), 2D visualization (n = 21), or cadaveric specimen (n = 22) of the pelvis. Medical and pre-medical student participants completed a multiple-choice pre-test and post-test during their respective learning session, and a long-term retention (LTR) test 2 months later. Results showed no difference in anatomy test improvement or LTR performance between the experimental groups. A simple linear regression analysis showed that within the 3D group, participants with high Vz tended to retain more than those with low Vz on the LTR test (R² = 0.31, P = 0.01). The low Vz participants may be cognitively overloaded by the complex spatial cues from the 3D stereoscopic model. Results of this study should inform resource selection and curriculum design for health professional students, with attention to the impact of Vz on learning.     

Gauging e-government: A report on implementing services among American cities

Municipalities face a dilemma as they pursue technologically enabled modes of providing traditional services. The planning stages of e-government amount to triage: which specific municipal functions and services can a municipality afford to implement (or which services can they afford not to implement) given the costs of technology and technological capability? Little in the way of defining the leading edge of innovation among cities exists. To date, the literature on e-government “best practices” tends to stress creating standards for evaluating web-enabled services rather than for benchmarking the actual status of e-government implementation. In other words, a well-developed literature is emerging around standards by which municipal websites can be evaluated such as navigability and content standards. These standards do not give us insight, however, into the specific functions and services as they emerge on municipality websites. As a means toward addressing this lacuna, the authors created a rubric for benchmarking implementation among cities nationwide using a broad range of functional dimensions and assigning municipalities “e-scores.” In this paper, the authors describe these efforts, their approach and their findings.     

Teaching the teacher: exploring STEM graduate students’ nature of science conceptions in a teaching methods course

ABSTRACT

Graduate students regularly teach undergraduate STEM courses and can positively impact students’ understanding of science. Yet little research examines graduate students’ knowledge about nature of science (NOS) or instructional strategies for teaching graduate students about NOS. This exploratory study sought to understand how a 1-credit Teaching in Higher Education course that utilised an explicit, reflective, and mixed-context approach to NOS instruction impacted STEM graduate students’ NOS conceptions and teaching intentions. Participants included 13 graduate students. Data sources included the Views of Nature of Science (VNOS-Form C) questionnaire administered pre- and post-instruction, semi-structured interviews with a subset of participants, and a NOS-related course project. Prior to instruction participants held many alternative NOS conceptions. Post-instruction, participants’ NOS conceptions improved substantially, particularly in their understandings of theories and laws and the tentative nature of scientific knowledge. All 12 participants planning to teach NOS intended to use explicit instructional approaches. A majority of participants also integrated novel ideas to their intended NOS instruction. These results suggest that a teaching methods course for graduate students with embedded NOS instruction can address alternative NOS conceptions and facilitate intended use of effective NOS instruction. Future research understanding graduate students' NOS understandings and actual NOS instruction is warranted.     

Group communication and problem‐solving effectiveness I: A critical review of inconsistent findings

A review of the existing research literature indicates that, for the most part, researchers have generally failed to identify consistent and meaningful relationships between group interaction and group performance. This has led to a growing concern among small group scholars that unless a suitable explanation can be advanced to account for such failure, it may be necessary to re‐examine the widely held assumption that group interaction plays an important role in effective group performance. This paper attempts to explain why previous research has failed to identify consistent and meaningful relationships between group interaction behaviors and group performance outcomes. In addition, it offers an alternative approach to investigating the possible relationships between group interaction and group performance.     

Perceptions of childhood caretakers and borderline personality symptomatology

Previous studies indicate that individuals with borderline personality disorder come from families marked by high levels of psychopathology as well as dysfunctional parenting styles—themes that tend to engender negative attitudes toward parents. However, we are not aware of any studies that have examined perceptions of parenting quality and borderline personality symptoms in a clinical but non-psychiatric population—the purpose of the present study. Using a cross-sectional self-report survey methodology in a sample of internal medicine outpatients, we examined participants’ perceptions of the quality of parental caretaking using a one-item assessment, and examined borderline personality symptomatology using two measures. Ratings of the quality of parental care were statistically significantly inversely correlated with scores on both measures of borderline personality symptomatology. After controlling for the number of caretakers during childhood, the observed statistical relationships remained statistically significant. In this primary care sample, participants with borderline personality symptomatology perceived parents more negatively than those without such symptomatology.     

Dialogic voices in talk about drinking and pregnancy

Alcohol use during pregnancy poses a significant risk of fetal alcohol syndrome. This study presents the interpretive findings of the formative research phase of a funded grant to develop a community-based public health media campaign on the topic of drinking during pregnancy. In the initial wave of data collection, 50 rural women were recruited from four Women, Infants, and Children (WIC) clinics in southeastern Iowa to participate in semi-structured interviews. In the second wave, 10 additional WIC clients were interviewed for member-checking purposes. Findings revealed two competing discourses that organized these women's attitudes, beliefs, and behaviors surrounding drinking and pregnancy: the discourse of individualism and the discourse of responsible motherhood. These two discourses offer opposing normative guidelines for talk among their close female relatives and friends. The implications of these findings for designing a community-based media campaign are discussed.
