The Impact of Two- and Three-Generational Black Family Structure on Perceived Family Climate

This study examined the effect of black family structure on the perceived social climate as measured by the Family Environment Scale. The 64 black families were selected to fill the four cells of a 2 × 2 factorial design of 1- versus 2-parent black families by grandmother residing in the home of the family versus living 10 or more miles away. The family climate was significantly different among the four family structures and between this sample and the normative sample of Moos and his associates. No significant differences were found among the family structures on their Family Incongruence scores. The subscale scores of this black sample were similar to the scores of other black and partly black samples. These results suggest that black families are not a homogeneous group, but rather different black family structures are associated with different family climates. Further research is needed to understand the impact family climate has on child-rearing practices and child outcomes within these diverse family structures.     

Emergent literacy profiles among prekindergarten children from low-SES backgrounds: Longitudinal considerations

This study represents a longitudinal follow-up to a prior investigation that identified five profiles of emergent literacy skills among children in the fall of their prekindergarten year. Here, we examined: (a) how profile patterns changed from fall to spring, (b) the extent to which children remained stable in their profile membership, and (c) possible factors that may explain children's movement in profile membership from fall to spring. Participants were 484 children enrolled in needs-based programs. Eight measures of emergent literacy, across oral language and code-related domains, were administered in both the fall and the spring of the prekindergarten year. Latent profile analysis was used to classify children into fall and spring profiles (N = 484, 369, respectively). Although there were fewer profiles identified in the spring, children's membership within the profiles was characterized by a degree of stability, especially in the extremes of performance. Among children who shifted membership from fall to spring (35%), movement to a more desirable profile was primarily associated with children's emergent literacy skills, particularly oral language, at the beginning of the prekindergarten year.     

The role of sexual orientation in predicting outcome value and anticipated communication behaviors

The purpose of this study was to (1) examine the role of sexual orientation in determining a positive or negative predicted outcome value during an initial interaction, and (2) to test whether the predicted outcome value (POV) was related to anticipated communication behaviors. Participants (N = 284) completed one of two surveys. The surveys differed only in terms of the opening scenario, which introduced a fictitious target whose sexual orientation was manipulated. The data from this study suggest that learning of an individual's sexual orientation during an initial encounter negatively influences predicted outcome value and anticipated communication behaviors. Additionally, men continue to predict outcome values that are significantly more negative than those predicted by women. The results from this study remain important especially in light of recent research in which interpersonal contact with gays and lesbians has been shown to influence positively heterosexuals’ attitudes toward this minority group.     

Students' science perceptions and enrollment decisions in differing learning cycle classrooms

This investigation examined 10th‐grade biology students' decisions to enroll in elective science courses, and explored certain attitudinal perceptions of students that may be related to such decisions. The student science perceptions were focused on student and classroom attitudes in the context of differing learning cycle classrooms (high paradigmatic/high inquiry, and low paradigmatic/low inquiry). The study also examined possible differences in enrollment decisions/intentions and attitudinal perceptions among males and females in these course contexts. The specific purposes were to: (a) explore possible differences in students' decisions, and in male and female students' decisions to enroll in elective science courses in high versus low paradigmatic learning cycle classrooms; (b) describe patterns and examine possible differences in male and female students' attitudinal perceptions of science in the two course contexts; (c) investigate possible differences in students' science perceptions according to their decisions to enroll in elective science courses, participation in high versus low paradigmatic learning cycle classrooms, and the interaction between these two variables; and (d) examine students' explanations of their decisions to enroll or not enroll in elective science courses. Questionnaire and observation data were collected from 119 students in the classrooms of six learning cycle biology teachers. Results indicated that in classrooms where teachers most closely adhered to the ideal learning cycle, students had more positive attitudes than those in classrooms where teachers deviated from the ideal model. Significantly more females in high paradigmatic learning cycle classrooms planned to continue taking science course work compared with females in low paradigmatic learning cycle classrooms. Male students in low paradigmatic learning cycle classrooms had more negative perceptions of science compared with males in high paradigmatic classrooms, and in some cases, with all female students. It appears that using the model as it was originally designed may lead to more positive attitudes and persistence in science among students. Implications include the need for science educators to help teachers gain more thorough understanding of the learning cycle and its theoretical underpinnings so they may better implement this procedure in classroom teaching. © 2001 John Wiley & Sons, Inc.

Online Communities of Practice: A Catalyst for Faculty Development

This article addresses the concept of communities of practice and how it has come of age for the professional development of professors as teachers. Thanks to current technological options, faculty developers can enhance the opportunity for the entire faculty to learn through the use of online communities. Designing a faculty development portal using community of practice concepts can be an effective means to jump-start, facilitate, develop, and sustain faculty involvement in academic communities.     

Learning Through Case Comparisons: A Meta-Analytic Review

Over the past 20 years, there has been much research on how people learn from case comparisons. This work has implemented comparison activities in a variety of different ways across a wide range of laboratory and classroom contexts. In an effort to assess the overall effectiveness of case comparisons across this diversity of implementation and contexts and to explore what variables might moderate learning outcomes, we conducted a meta-analysis of 57 experiments with 336 tests. Random effects analyses of the 336 tests revealed that case comparison activities commonly led to greater learning outcomes than other forms of case study including sequential, single case, and nonanalogous, as well as traditional instruction and control (d = .50), 95% CI [.44, .56]. Of 15 potential moderators, four variables were found to reliably moderate the effectiveness of case comparisons: the objective of the comparison, the presentation of a principle, the content, and the lag between the comparison and testing. Asking learners to find similarities between cases, providing principles after the comparisons, using perceptual content, and testing learners immediately are all associated with greater learning. We conclude with a discussion of the theoretical and practical implications of these results for cognitive theory and classroom practice.     

Evaluation of the effectiveness of 3D vascular stereoscopic models in anatomy instruction for first year medical students

The head and neck region is one of the most complex areas featured in the medical gross anatomy curriculum. The effectiveness of using three‐dimensional (3D) models to teach anatomy is a topic of much discussion in medical education research. However, the use of 3D stereoscopic models of the head and neck circulation in anatomy education has not been previously studied in detail. This study investigated whether 3D stereoscopic models created from computed tomographic angiography (CTA) data were efficacious teaching tools for the head and neck vascular anatomy. The test subjects were first year medical students at the University of Mississippi Medical Center. The assessment tools included: anatomy knowledge tests (prelearning session knowledge test and postlearning session knowledge test), mental rotation tests (spatial ability; presession MRT and postsession MRT), and a satisfaction survey. Results were analyzed using a Wilcoxon rank‐sum test and linear regression analysis. A total of 39 first year medical students participated in the study. The results indicated that all students who were exposed to the stereoscopic 3D vascular models in 3D learning sessions increased their ability to correctly identify the head and neck vascular anatomy. Most importantly, for students with low‐spatial ability, 3D learning sessions improved postsession knowledge scores to a level comparable to that demonstrated by students with high‐spatial ability indicating that the use of 3D stereoscopic models may be particularly valuable to these students with low‐spatial ability.

The implications of an across-the-board salary increase

The implications of an across-the-board salary increase for selected outcomes are assessed. While such an approach to employee compensation is easily administered, the results of this analysis suggest that such an approach has some long-run costs. Those perceiving themselves as high performers and as putting forth greater effort felt undercompensated. Those with feelings of being undercompensated, relative to those feeling equitably compensated, anticipated a reduction in their job performance during the coming year, and perceived a deterioration in the association between performance and compensation. Differences in intentions to search for alternative employment are statistically significant.     

Outcomes assessment: an examination of the ETS major field test and the comprehensive business exam

This study is the first to examine student performance differences between the major field test in business (MFTB) and the comprehensive business exam (CBE). Results reveal students performed at a statistically significant 50.8 percentile ranking on the CBE compared to a 38.0 percentile ranking on the MFTB. Additionally, this study finds that students transferring business core courses with a grade point average (GPA) of 2.5 or lower perform at a statistically significant lower level on both the MFTB and the CBE than those transferring business core courses with GPAs higher than 2.5. These findings have important implications for assessment of learning purposes.
