Anatomical Sciences Education Vol. 4, Issue 5, 2011 Cover Image

Drawing session from an art and anatomy workshop for medical students at the University of Texas Health Science Center at San Antonio and art students at the University of Texas at San Antonio. A current trend in medical education is to integrate aspects of the humanities into the medical school curriculum. In this issue of ASE, Dr. Charleen Moore and her colleagues describe an art and anatomy workshop that uses drawing exercises to increase observational skills, to foster the development of humanistic sensitivities, and to emphasize the emotional aspects of dealing with mortality.

SMEC (her/his)tories

This collection of historical accounts provides diverse perspectives on the structure and culture of the community of researchers who completed their studies under the mentorship of researchers at SMEC. These her/histories provide multiple perspectives on the goals and values that motivated educators to become SMEC scholars.     

Child care and family processes: Bi-directional relations between child care quality,home environments,and maternal depression

The current study examined whether within-family changes in child care quality and quantity predicted subsequent changes in home environment quality and maternal depression across early childhood (6 to 54 months of age). Data were drawn from the NICHD Study of Early Child Care and Youth Development (n = 1239; 77% White; 48% female; data collection from 1991 to 1996), and were analyzed using Random Intercept Cross-Lagged Panel Models. Within-family increases in child care quality predicted modest increases in home environment quality (β = .13–.17). These effects were most robust from child age 6 to 15 months. Increases in child care quality produced small, statistically non-significant, reductions in depression. Time-specific increases in child care quantity were not consistently predictive of either outcome.     

A psychometric evaluation of the digital logic concept inventory

Concept inventories hold tremendous promise for promoting the rigorous evaluation of teaching methods that might remedy common student misconceptions and promote deep learning. The measurements from concept inventories can be trusted only if the concept inventories are evaluated both by expert feedback and statistical scrutiny (psychometric evaluation). Classical Test Theory and Item Response Theory provide two psychometric frameworks for evaluating the quality of assessment tools. We discuss how these theories can be applied to assessment tools generally and then apply them to the Digital Logic Concept Inventory (DLCI). We demonstrate that the DLCI is sufficiently reliable for research purposes when used in its entirety and as a post-course assessment of students’ conceptual understanding of digital logic. The DLCI can also discriminate between students across a wide range of ability levels, providing the most information about weaker students’ ability levels.     

Environmental inequality and disparities in school readiness: The role of neurotoxic lead

Developmental science has increasingly scrutinized how environmental hazards influence child outcomes, but few studies examine how contaminants affect disparities in early skill formation. Linking research on environmental inequality and early childhood development, this study assessed whether differences in exposure to neurotoxic lead explain sociodemographic gaps in school readiness. Using panel data tracking a representative sample of 1266 Chicago children (50% female, 16% White, 30% Black, 49% Hispanic, μ_age = 5.2 months at baseline, collected 1994–2002), analyses quantified the contribution of lead contamination to class and racial disparities in vocabulary skills and attention problems at ages 4 and 5. Results suggested that lead contamination explains 15%–25% and 33%–66% of the disparities in each outcome, respectively, although imprecise estimates preclude drawing firm inferences about attention problems.
