Are Anatomy PhDs Nearing Extinction or Adapting to Change? United States Graduate Education Trends in the Anatomical Sciences

Faculty qualified to teach in the anatomical sciences are growing scarce just as the need for trained anatomists is greater than ever. Enrollments are surging in anticipation of a large physician shortfall; meanwhile, many anatomists are reaching retirement age. Who will fill the teaching gap? This study assessed trends in doctorates awarded in Anatomy and related fields within the United States (US) since 1969 and evaluated modern graduate education in the anatomical sciences. Data were compiled from the National Science Foundation Survey of Earned Doctorates. The total number of doctorates in the anatomical sciences and number of doctorates by sex and race/ethnicity were plotted for trend analysis. The number of PhD anatomy training programs within US medical schools was also assessed. Curricula and major characteristics of all active programs were evaluated through website searches and program director interviews. While doctorates in cell biology, developmental biology, and neuroscience have grown, the number of PhDs awarded in Anatomy has declined, on average, by 3.1 graduates per year to a 50-year low of only 8 graduates in 2017. Currently, 21 active doctoral programs in anatomy operate within US medical schools and fall into three general categories: anatomy education (n = 8), classic anatomy (n = 8), and anthropology/evolutionary anatomy (n = 5). Without a concerted effort by stakeholders to address the shortage, anatomists may face extinction. Expansion of the anatomy education doctoral degree may represent a necessary evolution of the field to meet job market needs and to thwart the extinction threat.     

Change in teacher education: How holmes was hijacked

Summary A movement among universities noted for research and for rigorous scholarship that would have insured a significantly improved education for prospective teachers was transformed in a short time, about ten years, into another agency of centrally inspired “school refrom,” The Holmes Group’s initial program called for prospective teachers to undergo five years of general education and teacher education, devoting the undergraduate years largely to arts and sciences. It also called for a closer collaboration between teacher educators and arts and science faculty in order to prepare preservice teachers to teach more rigorous pedagogically organized subject matter. Included in the early Holmes agenda was the concept of a professional development school as a public school site for pedagogical application, under the direction of veteran teacher cadres. However, as a consequence of an increasingly liberal academic ideology, informing a persistent criticism of Holmes’s original proposals as elitist and insufficiently activist, the Holmes group came in a short time to underplay its call for a five-year program, to back off from a closer collaboration between teacher educators and arts and sciences faculty, and to transform its concept of an affiliated public school from a site for pre-service pedagogical classroom practice into an exemplary school-to-be. Some hope may remain: the Holmes staff recently distributed the “Conference Proceedings” of the January 1998 annual convention held in Orlando. On page 42 of those proceedings, Arthur Wise, the peripatetic head of NCATE (National Council for Accreditation of Teacher Education—now a Holmes “partner” at the national level) found Holmes neglectful of an appropriate concern for arts and sciences education for prospective teachers. Wise was a “ranconteur” in Orlando; as such he was expected to provide a “reflective response” to the conference. He said, apologetically, I might offer my one sound of criticism ... I just worry when I see that ... we may be paying too much attention to the external aspects of school and maybe not enough to the guts of the matter which is, after all, content and how to teach it.     

Fostering Intrinsic Motivation in Early Childhood Classrooms

Young children are born with an innate curiosity to learn about their world. This intrinsically instigated learning is often called mastery motivation. Patterns of motivation are established at an early age. The early childhood years are crucial for establishing robust intrinsic motivational orientations which will last a lifetime. By the time many children reach school, much of their motivation has been lost or replaced with extrinsically motivated learning strategies. Preschools and elementary schools have been criticized for contributing to such negative motivational patterns in children. This can be changed. Early child care situations and preschools can instead be instrumental in the strengthening of children's motivation. The goal of this paper is to show that through an understanding of the beginnings of motivation, we can begin to find ways to build strong motivational patterns in children that can carry on to later years of learning.     

Relative Heights of Males and Females in Children's Drawings Taille Relative des Silhouettes Masculines et Fe´minines dans les Dessins d'Enfants Alturas Relativas de las Figuras Masculina y Femenina en los Dibujos de los Niños

Two studies are reported concerning the height of male and female figures in children's drawings. In Study 1, 5 and 7 year olds were asked to draw a man and a lady or a boy and a girl. Adult figures were drawn taller than child figures. For boys, the mean heights of their male and female figures were approximately the same but girls drew their females taller than their male figures. The reason for this was that more girls than boys used different structures (incorporating a skirt or trousers into the drawing) to differentiate their figures; this use of different structures results in a taller drawing of a skirted figure. This finding was replicated in Study 2 in which 7-year-olds were asked to draw a lady in a skirt and another in pyjamas: the skirted figure was taller when it had a different structure from the figure in pyjamas, whereas the mean heights of both figures were approximately the same height when the same structure had been used. Deux travaux de recherche ont étudié la taille des silhouettes masculines et féminines dans les dessins d'enfants. Dans l'étude 1, des enfants de 5 et 7 ans ont dû dessiner un homme et une femme ou un garçon et une fille. Les silhouettes adultes ont été dessinées plus grandes que les silhouettes d'enfants. Les garçons ont dessiné des silhouettes d'hommes et de femmes à peu près de la même taille en moyenne, mais les filles ont dessiné leurs femmes plus grandes que leurs hommes. La raison en est que plus de filles que de garçons utilisaient des structures différentes (en incorporant une jupe ou un pantalon dans le dessin) pour différencier leurs silhouettes; cette utilisation de structures différentes résulte en un dessin plus haut de la silhouette en jupe. Ces résultats se retrouvent dans l'étude 2, où des enfants de 7 ans ont dû dessiner une dame en jupe et une autre en pyjama: la silhouette en jupe était plus haute quand elle avait une structure différente de celle en pyjama, tandis que la hauteur moyenne des deux silhouettes était à peu près la même quand la même structure était utilisée. Se informa de dos estudios relacionados con la altura de las figuras masculina y femenina en los dibujos de los niños. En el Estudio 1, se pidió a niños de 5 y 7 años que dibujan un hombre y una mujer, o un chico y una chica. Las figuras adultas fueron dibujadas con una altura mayor que las figuras de niños. Para los niños, las alturas medias de sus figuras masculinas y femeninas fueron aproximadamente las mismas, pero las niñas dibujaron sus figuras femeninas más altas que las masculinas. La razón para esto fue que más niñas que niños usaron estructuras diferentes (incorporando una falda o pantalones en el dibujo) para diferenciar sus figuras. El uso de estas estructuras diferentes resulta en un dibujo más alto de una figura con falda. Este hallazgo se reprodujo en el Estudio 2, en el que se pidió a niños de 7 años que dibujaran una señora con una falda y otra con un pijama: la figura con falda fue más alta cuando tuvo una estructura diferente a la de la figura con pijama, mientras que las alturas medias de ambas figuras fueron aproximadamente la misma altura cuando la hizo uso de la misma estructura.     

Biological significance attenuates overshadowing, relative validity, and degraded contingency effects

Miller and Matute (1996) showed that blocking is attenuated when the blocked conditioned stimulus (CS) is “biologically significant” (i.e., when the CS has the potential to elicit vigorous responding of any kind). To the extent that blocking is representative of cue competition, this finding suggests that biological significance protects CSs against cue competition effects in general. In the present experiments, we tested this possibility by examining the influence of biological significance of CSs on other examples of cue competition, namely, overshadowing, the relative stimulus validity effect, and the degraded contingency effect in rats. In Experiment 1, we found that intense auditory stimuli induced transient unconditioned lick suppression, thereby indicating that intense sounds were of high inherent biological significance. In Experiment 2A, we found that cues with high inherent biological significance were protected from overshadowing. In Experiment 2B, this finding was extended to cues with high acquired biological significance, which was obtained through prior pairings with a reinforcer of the valence opposite to that used in the overshadowing treatment. In Experiments 3 and 4, we found that cues with high inherent biological significance attenuated the relative validity effect and the degraded contingency effect, respectively. These results lend support to the view that biological significance (inherent and acquired) protects stimuli from cue competition effects, a finding that is problematic for many contemporary theories of learning.
