Effective And Ineffective Clinical Teaching And Instruction In Dental Hygiene School, Vicki Gianopoulos Pizanis

Teacher Education, Educational Leadership & Policy ETDs

Introduction

Educators who teach in a clinical setting, primarily in healthcare fields, while having knowledge of the subject, having skills in what is taught, and having experience in the field, often have little-to-no training in teaching. This results in instructional practices being based upon intuition and experience. Becoming aware of how qualities and characteristics of clinical instructors affect adult learners’ educational experience through evidence-based research, and using its implications, would help promote more effective instruction and ultimately improve student learning.

Methodology

A mixed methods study using Grounded Theory and Critical Incidence technique was conducted to study junior student, senior student …

Pathogenic gene fusions have been identified in several histologic types of salivary gland neoplasia, but not previously in acinic cell carcinoma (AcCC). To discover novel gene fusions, we performed whole-transcriptome sequencing surveys of three AcCC archival cases. In one specimen we identified a novel HTN3-MSANTD3 gene fusion, and in another a novel PRB3-ZNF217 gene fusion. The structure of both fusions was consistent with the promoter of the 5' partner (HTN3 or PRB3), both highly expressed salivary gland genes, driving overexpression of full-length MSANTD3 or ZNF217. By fluorescence in situ hybridization of an expanded AcCC case series, we observed MSANTD3 rearrangements …
