Food Fish Identification from DNA Extraction Through Sequence Analysis

This experiment exposed 3rd and 4th y undergraduates and graduate students taking a course in advanced food analysis to DNA extraction, polymerase chain reaction (PCR), and DNA sequence analysis. Students provided their own fish sample, purchased from local grocery stores, and the class as a whole extracted DNA, which was then subjected to PCR, gel electrophoresis, and Sanger sequencing. Students retrieved their sequences and identified their fish using the NCBI BLAST nucleotide database. Slightly more than half of the samples yielded sequences identical or close to expected (based on the identification of the fish on the packaging); some other samples matched unanticipated fish or other organisms, due to an incomplete database, minor sequencing errors, or laboratory contamination (human and fungal sequences); 1 canned tuna sample identified as hake could represent food fraud.     

Losing the whole child? A national survey of primary education training provision for spiritual,moral, social and cultural development

International concerns about the performativity agenda in schools gives rise to concerns about the neglect of a holistic approach to teaching and learning. Whilst schools in England and Wales are legally obliged to promote the spiritual, moral, social and cultural (SMSC) development of children, little is known about how initial teacher training providers prepare trainees to do so. This project aims to address this gap in the literature. This paper details the findings of phase one of a National Survey which investigates trainers’ approaches to delivery and their views on the place of SMSC in primary schools. Findings suggest that trainers value SMSC, but time devoted to it is relatively low and policy changes are perceived to threaten SMSC’s security. The paper argues that it is vital that trainers empower trainees to understand the importance of holistic themes of their respective curricula, informed by critical engagement with theory, in order to avoid them being overshadowed by the performativity discourse.     

Virtual cerebral ventricular system: an MR-based three-dimensional computer model

The inherent spatial complexity of the human cerebral ventricular system, coupled with its deep position within the brain, poses a problem for conceptualizing its anatomy. Cadaveric dissection, while considered the gold standard of anatomical learning, may be inadequate for learning the anatomy of the cerebral ventricular system; even with intricate dissection, ventricular structures remain difficult to observe. Three-dimensional (3D) computer reconstruction of the ventricular system offers a solution to this problem. This study aims to create an accurate 3D computer reconstruction of the ventricular system with surrounding structures, including the brain and cerebellum, using commercially available 3D rendering software. Magnetic resonance imaging (MRI) scans of a male cadaver were segmented using both semiautomatic and manual tools. Segmentation involves separating voxels of different grayscale values to highlight specific neural structures. User controls enable adding or removing of structures, altering their opacity, and making cross-sectional slices through the model to highlight inner structures. Complex physiologic concepts, such as the flow of cerebrospinal fluid, are also shown using the 3D model of the ventricular system through a video animation. The model can be projected stereoscopically, to increase depth perception and to emphasize spatial relationships between anatomical structures. This model is suited for both self-directed learning and classroom teaching of the 3D anatomical structure and spatial orientation of the ventricles, their connections, and their relation to adjacent neural and skeletal structures.

Phenomenological understanding of Black counselor education students at Predominately White Institutions,Historically Black Colleges and Universities,and Hispanic Serving Institutions

The experiences of Black counseling students at Predominantly White Institutions are well documented. Using a transcendental phenomenological environmental research design, we explored how 12 Black counselor education graduates experienced their respective institutions across three types of academic institutions—Predominantly White Institutions, Historically Black Colleges and Universities, and Hispanic Serving Institutions. Three salient themes emerged—(1) exposure, (2) real-life exposure, and (3) cultural oasis. The researchers also discussed implications for counselor education programs and future research.     

A Survey Study of Early Childhood Teachers’ Beliefs and Confidence about Teaching Early Math

This study reports on results from the Early Mathematics Beliefs and Confidence Survey, administered to 346 preschool teachers in a large public school system in the Midwest. Survey results depict a much more positive view of teachers’ beliefs and confidence in early math teaching than previously reported. Results also suggest that teacher confidence varies with specific types of math knowledge and teaching abilities, and assessing math learning is a specific area where teachers lack confidence. Examining confidence in their math abilities and in teaching early math, results indicate that teachers are more confident teaching math and remain confident in teaching even when confidence in their abilities is low. Implications of results for early math professional development are discussed.     

Talent development,work habits,and career exploration of Chinese middle‐school adolescents: development of the Career and Talent Development Self‐Efficacy Scale

This article describes the development of an instrument – the Career and Talent Development Self‐Efficacy Scale (CTD‐SES) – for assessing students’ self‐efficacy in applying life skills essential for personal talent development, acquisition of positive work habits, and career exploration. In Study 1, data were obtained from a large sample of Chinese middle‐school students (N=15,113) in Grades 7–9 in Hong Kong. The CTD‐SES is an 18‐item questionnaire with subscales containing items that address students’ orientations toward developing their own talents, acquiring and applying positive work habits, and exploring their career possibilities. Evidence is provided for internal consistency, temporal stability, and factor structure of the CTD‐SES. Goodness of fit statistics provided support for a three‐primary‐factor‐plus‐higher‐factor model, and this solution was used in the statistical analyses. The data also indicated that students with plans for university study reported significantly higher scores than those without on all three domains of career and talent development. In Study 2 (N=308) Grade 10 high‐ability students’ scores in CTD‐SES were correlated with scores in career decision self‐efficacy and academic performance. The development and validation of CTD‐SES is the first step toward investigating career exploration, work habits, and talent development among Asian middle‐school adolescents.
