Two‐dimensional sectioned images and three‐dimensional surface models for learning the anatomy of the female pelvis

In the Visible Korean project, serially sectioned images of the pelvis were made from a female cadaver. Outlines of significant structures in the sectioned images were drawn and stacked to build surface models. To improve the accessibility and informational content of these data, a five‐step process was designed and implemented. First, 154 pelvic structures were outlined with additional surface reconstruction to prepare the image data. Second, the sectioned and outlined images (in a browsing software) as well as the surface models (in a PDF file) were placed on the Visible Korean homepage in a readily‐accessible format. Third, all image data were visualized with interactive elements to stimulate creative learning. Fourth, two‐dimensional (2D) images and three‐dimensional (3D) models were superimposed on one another to provide context and spatial information for students viewing these data. Fifth, images were designed such that structure names would be shown when the mouse pointer hovered over the 2D images or the 3D models. The state‐of‐the‐art sectioned images, outlined images, and surface models, arranged and systematized as described in this study, will aid students in understanding the anatomy of female pelvis. The graphic data accompanied by corresponding magnetic resonance images and computed tomographs are expected to promote the production of 3D simulators for clinical practice.

Development of PCK for novice and experienced university physics instructors: a case study

The current study assessed and compared university students' perceptions' of a novice and an experienced physics instructor's Pedagogical Content Knowledge (PCK). Two college physics instructors and 116 students voluntarily participated in this study. The research model comprised three workshops, mid-term and final evaluations and instructor interviews. The results showed that each instructor's PCK performance in four categories was slightly improved, though the difference was not statistically significant and only the category of Instructional Representation and Strategies (IRS) was found to be statistically different by students' evaluations of their instructor's PCK. The experienced instructor emphasized life examples and experiments, whereas, the novice instructor emphasized explanations and quizzes. Furthermore, the PCK questionnaire provided university instructors with adequate information so the instructors could receive students' feedback as available sources to reflect on their teaching to improve their quality of teaching. Research implications of this study are provided along with suggestions for future research.     

Minding the Gaps in Absenteeism: Disparities in Absenteeism by Race/Ethnicity,Poverty and Disability

ABSTRACT

Children from certain racial and ethnic minority backgrounds, in poverty, and/or with a disability, often face distinct challenges in attending school, leading them to miss more school relative to their non-minority, more socio-economically advantaged and non-disabled peers. This brief describes these disparities in absenteeism in the US, discusses the challenge of explaining these disparities, and considers the implications that disparities have for addressing absenteeism. Finally, it closes with advice on how schools can make headway in reducing disparities in absenteeism. As this brief argues, while schools can readily document absenteeism gaps, diagnosing the root causes of these gaps remains much more elusive. Further, schools seeking to reduce disparities in absenteeism will not only need to intentionally establish explicit targets to reduce such gaps, but they will need to develop individualized strategies to remove barriers to attendance thereby getting children—especially those facing disproportionate challenges—back into the classroom.     

Exploratory analysis of decentralized governance and its implications for the equity of early childhood education services in four countries of Europe and Central Asia

We conducted a qualitative study in four countries of the Europe and Central Asia (ECA) region and explored the Early Childhood Education (ECE) policy landscape with an emphasis on the challenges and opportunities decentralization has presented for the provision of services. We content-analyzed ECE policies and documents to map national approaches to ECE. Key informant interviews were conducted to assess the implementation of decentralized ECE governance. An analytical framework that combined core constructs of ECE systems and key domains of decentralization (autonomy, institutional capacity and accountability) was developed and applied. Our analysis points to four overarching processes that contribute to the perpetuation and possible increase of inequitable ECE including (1) sparse mechanisms for participatory and autonomous policy formulation, with few systematic efforts to strengthen local institutional capacities; (2) fragmented policy approaches to promote the assessment and strengthening of quality at scale; (3) funding frameworks and financing schemes that tend to benefit enrolment in contexts of higher levels of economic development; and (4) few mechanisms for coordination to ensure operational coherence across the ECE sector.
