Actual Teaching

Inquiry-style laboratory courses, in which students engage in open-ended projects rather than a prescribed set of experimental steps (“cookbooks”), are becoming increasingly popular at the undergraduate level. Reformed curricula require reforms in training teachers; in the case of large universities, laboratory instructors are typically graduate teaching assistants (TAs). The General Chemistry Laboratory courses at a large, public, research-intensive university in the Midwestern region of the United States recently underwent a transformation from a “cookbook” to a project-based lab, and despite efforts to improve training, TAs continue to express difficulty teaching the course. To determine the source of these difficulties, we conducted multiple video observations and semi-structured interviews with seven TAs throughout one semester. We report TAs’ beliefs about what is expected of them, their philosophical alignment to perceived expectations, and a comparison of the Lab Coordinator's expectations to TAs’ actual teaching practices. We found that the TAs generally agreed with behaviors they were expected to perform, but responses to actions they were not supposed to do indicated that they were unsure of what the Lab Coordinator expected and personally believed that an ideal TA would perform those actions. This work highlights a need to clearly communicate the aims and expectations in a course and the rationale for those choices.

Typical Experiment

ABSTRACTIn a general chemistry course, while the hands-on experience of the laboratory is important, the goals of the laboratory are not fulfilled until the calculations and analysis are complete. Quite often students are capable of following laboratory instructions and generating excellent data, only to fail in the data analysis, which rarely occurs in the confines of the laboratory or the presence of the instructor. All too often, students are unable to learn important information from the interpretation of experimental results and draw correct conclusions because they make calculational errors, which are most often discovered by the instructor in the grading process. There is an opportunity for distance learning to help bridge the gap between collection of data and its correct analysis. At the United States Naval Academy (USNA), we have developed a Web-based system where the students input their data and calculational results into a web form with immediate feedback. The students are then allowed to correct their errors and resubmit. This system has been in successful use for 5 years. A description of a typical experiment will be discussed along with an assessment of student and faculty satisfaction with the program.

Trade Offs

The author of this article argues that the two-decades-long litigation struggle was necessary to push the political actors in Mississippi into a more virtuous than vicious legal/political negotiation. The second and related argument, however, is that neither the 1992 United States Supreme Court decision in Fordice nor the negotiation provided an adequate riposte to plaintiffs’ claims. The author shows that their chief counsel for the first phase of the litigation wanted equality of opportunity for historically black colleges and universities (HBCUs), as did the plaintiffs. In the course of explicating the role of a legal grass-roots humanitarian, Coleman suggests lessons learned and trade-offs from that case/negotiation, describing the tradeoffs as part of the political vestiges of legal racism in black public higher education and the need to move HBCUs to a higher level of opportunity at a critical juncture in the life of tuition-dependent colleges and universities in the United States. Throughout the essay the following questions pose themselves: In thinking about the Road to Fordice and to political settlement, would the Justice Department lawyers and the plaintiffs’ lawyers connect at the point of their shared strength? Would the timing of the settlement benefit the plaintiffs and/or the State? Could plaintiffs’ lawyers hold together for the length of the case and move each piece of the case forward in a winning strategy? Who were plaintiffs’ opponents and what was their strategy? With these questions in mind, the author offers an analysis of how the campaign— political/legal arguments and political/legal remedies to remove the vestiges of de jure segregation in higher education—unfolded in Mississippi, with special emphasis on the initiating lawyer in Ayers v. Waller and Fordice, Isaiah Madison

Purpose: Examine if Historically Black Colleges and Universities (HBCUs) are more likely to be located in low food access area (LFA) census tracts compared to public non-HBCUs. Design: ArcGIS Pro was utilized to capture food environments and census tract sociodemographic data. Setting: The sample included 98 HBCUs and 777 public non-HBCUs within the United States. 28.9% of study census tracts were classified as LFA tracts. Measures: University data were gathered from the National Center for Education Statistics. Census tract-level LFA classification was informed by the United States Department of Agriculture’s Food Access Research Atlas. Covariates included population density and neighborhood socioeconomic status of census tracts containing subject universities. Analysis: Multilevel logistic regression was employed to examine the relationship between university type and LFA classification. Results: A higher percentage of HBCUs (46.9%) than public non-HBCUs (26.6%) were located in LFAs. After adjusting for population density and neighborhood socioeconomic status, university type was significantly associated with food access classification (B=0.71;p=.0036). The odds of an HBCU being located in LFA tracts were 104% greater than for a public non-HBCU (OR=2.04;95% CI=1.26,3.29). Conclusion: Findings underscore the need for policy interventions tailored to HBCU students to promote food security, environmental justice, and public health.
