Preparing Biology Graduate Teaching Assistants for Their Roles as Instructors: An Assessment of Institutional Approaches

The inconsistency of professional development (PD) in teaching for graduate teaching assistants (GTAs) is a widespread problem in higher education. Although GTAs serve an important role in retention of undergraduate science majors and in promotion of scientific literacy in nonmajors, they often lack preparation and ongoing support for teaching. Given the recent national focus on instructional quality in introductory courses, our goal was to use an online survey to identify current practices of teaching PD for biology GTAs and compare these results with the last national survey on this topic. In responses from 71 participant institutions, 96% reported some mandatory teaching preparation for biology GTAs; however, 52% of these programs required 10 or fewer hours per year. Respondents wanted to change their programs to include more pedagogical information and teaching observations with feedback to their GTAs. Programmatic self-ratings of satisfaction with GTA PD were positively correlated with the number of topics discussed during PD. Although more schools are requiring GTA PD for teaching compared with the last national survey, the lack of program breadth at many schools warrants a national conversation with regard to recent calls for improving undergraduate instruction.     

School psychologists and suicide risk assessment: Role perception and competency

As the second leading cause of death for adolescents, suicide is a major concern for school personnel. School psychologists' training in mental health makes them well-positioned to lead in suicide prevention efforts; however, studies have shown a lack of preparedness in crisis intervention and, more specifically, suicide risk assessment. This study surveyed practicing school psychologists (N = 92) to explore their perception of both their role and competency in suicide risk assessment. Suicide risk assessment was defined as a broad term pertaining to any measures taken in suicide prevention, intervention, or postvention. The majority of school psychologists reported having a primary role at the tertiary level (i.e., intervening with a student identified as needing help). Participants indicated lacking adequate graduate preparation; however, most participants were confident in their knowledge of suicide and suicide risk assessment and were comfortable identifying and intervening with a student who is suicidal. Implications for practice and directions for future research are discussed.     

Factors that May Influence Treatment Effects: Helping Practitioners Select Early Numeracy Interventions

Despite encouraging findings that show that interventions can improve students’ math understanding, achievement gaps in math often persist or even widen for students who struggle. Practitioners play a significant role in closing these achievement gaps because they have the responsibility to select or design interventions. Practitioners may wish to consider factors that influence intervention effectiveness. This study evaluated numeracy interventions and explored how features of the studies and interventions may have influenced reported effects. Exploratory analyses revealed smaller effects when only distal measures were considered (g = 0.35; SE = 0.05), or when studies reported including more than 30 percent of participants as English learners (g = 0.44; SE = 0.12). Results also indicated variable effects across the same intervention programs. Implications for practitioners related to selecting interventions are discussed.     

Development of a Novel Peer-sharing Application to Supplement Learning from Cadaveric Dissection

Gross anatomy dissection in contemporary medical education must balance the traditional value of learning from the cadaver with the possibilities created by the use of digital tools as supplemental resources that personalize and deepen the student learning experience. This study broadly examined the design, implementation, and use of AnatomyShare, a novel iPad application employing learner-generated content that allows students to securely share annotated images of their dissections with each other and take faculty-generated image-based quizzes during their first-year medical school gross anatomy course. Almost all students enrolled in the course used the application (N = 176; 91% use based on analytics). Seventy-five students responded to a survey asking how and when they used the application, along with their perceptions of its usefulness and contribution to learning. More students reported using the application outside of laboratory (97.3%) than during laboratory (85.3%), despite only in-laboratory use being required. Taking quizzes using the “Exam” feature was the highest rated use of AnatomyShare, and students cited that the application exposed them to anatomical variation and motivated them to correctly identify structures during dissection. While steps need to be taken to combat low-quality learner-generated content and to enhance meaningful student interaction and collaboration, AnatomyShare was a feasible and highly rated supplement to dissection that provided valuable assessment opportunities for students. Future research will examine the impact of use on course grades and engagement in gross anatomy dissection.     

Neurodevelopmental Effects of Early Deprivation in Postinstitutionalized Children

The neurodevelopmental sequelae of early deprivation were examined by testing ( N  =   132) 8- and 9-year-old children who had endured prolonged versus brief institutionalized rearing or rearing in the natal family. Behavioral tasks included measures that permit inferences about underlying neural circuitry. Children raised in institutionalized settings showed neuropsychological deficits on tests of visual memory and attention, as well as visually mediated learning and inhibitory control. Yet, these children performed at developmentally appropriate levels on similar tests where auditory processing was also involved and on tests assessing executive processes such as rule acquisition and planning. These findings suggest that specific aspects of brain-behavioral circuitry may be particularly vulnerable to postnatal experience.
