This study conducted a citation network analysis (CNA) of human performance technology (HPT) to examine its current state of the field. Previous reviews of the field have used traditional research methods, such as content analysis, survey, Delphi, and citation analysis. The distinctive features of CNA come from using a social network analysis approach to see relational and network patterns in the citation data. This CNA found that the Performance Improvement Quarterly network showed more widely but loosely connected and less centralized structural attributes than the human resource development network; the 10 most influential articles in the field were identified; frequently co‐cited articles were recognized as having a strong relationship by subsequent researchers; and five cohesive subgroups showed key topics in the field (performance, instructional design, performance support, organization/workplace, and transfer of training). Implications from the results of the CNA were elaborated on for future research in HPT.  相似文献

ABSTRACT

This paper concludes the Special Issue (SI) ‘Probing the Amalgam: the relationship between science teachers’ content, pedagogical and pedagogical content knowledge’. We review the five papers (Sorge et al; Gess-Newsome et al; Kind; Pitjeng-Mosabala and Rollnick; and Liepertz and Bronowski) by discussing evidence these present regarding the relationships between content knowledge (CK), pedagogical knowledge (PK) and pedagogical content knowledge (PCK); the development of CK, PK and PCK in novice and experienced secondary science teachers and how CK, PK and/or PCK impact students’ learning. In conclusion, we draw these findings together in offering proposals for future research via reconsideration of Shulman’s amalgam. This includes post-hoc examination of a PCK model known as ‘the Consensus Model’ (Gess-Newsome, [2015]. A model of teacher professional knowledge and skill including PCK: Results of the thinking from the PCK Summit. In A. Berry, P. J. Friedrichsen, & J. Loughran (Eds.), Re-examining Pedagogical Content Knowledge in Science Education (pp. 28–42). New York, NY: Routledge; Neumann, Kind, & Harms [2018]. Probing the amalgam: The relationship between science teachers’ content, pedagogical and pedagogical content knowledge. International Journal of Science Education, 1–15) and presentation of a novel PCK structure based on evidence from the SI studies.  相似文献

In 2015, student learning programs at the University of Saskatchewan moved organizationally to the university library. While these services resided physically in the library as part of the Learning Commons partnership, this recent change presents the library with a new focus and responsibility for broader student learning support and academic skill development. Highlighting examples of organizational integration of student learning support, this article uses a proximity perspective, suggesting that geographical proximity of services in the learning commons does not go far enough to achieve the deeper collaboration and integration necessary for holistic and integrated learning, and that organizational proximity is needed.  相似文献

In this study, the fibers of invasive species Agave americana L. and Ricinus communis L. were successfully used for the first time as new sources to produce cytocompatible and highly crystalline cellulose nanofibers. Cellulose nanofibers were obtained by two methods, based on either alkaline or acid hydrolysis. The morphology, chemical composition, and crystallinity of the obtained materials were characterized by scanning electron microscopy(SEM) together with energy-dispersive X-ray spectroscopy(EDX), dynamic light scattering(DLS), X-ray diffraction(XRD), and Fourier transform infrared(FTIR)spectroscopy. The crystallinity indexes(CIs) of the cellulose nanofibers extracted from A. americana and R. communis were very high(94.1% and 92.7%, respectively). Biological studies evaluating the cytotoxic effects of the prepared cellulose nanofibers on human embryonic kidney 293 T(HEK293 T) cells were also performed. The nanofibers obtained using the two different extraction methods were all shown to be cytocompatible in the concentration range assayed(i.e., 0-500 μg/mL). Our results showed that the nanocellulose extracted from A. americana and R. communis fibers has high potential as a new renewable green source of highly crystalline cellulose-based cytocompatible nanomaterials for biomedical applications.  相似文献

The role of spelling recognition was examined in word reading skills and reading comprehension for dyslexic and nondyslexic children. Dyslexic and nondyslexic children were matched on their raw word reading proficiency. Relationships between spelling recognition and the following were examined for both groups of children: verbal ability, working memory, phonological measures, rapid naming, word reading, and reading comprehension. Children’s performance in spelling recognition was significantly associated with their skills in word reading and reading comprehension regardless of their reading disability status. Furthermore, spelling recognition contributed significant variance to reading comprehension for both dyslexic and nondyslexic children after the effects of phonological awareness, rapid naming, and word reading proficiency had been accounted for. The results support the role of spelling recognition in reading development for both groups of children and they are discussed using a componential reading fluency framework.  相似文献

This article explores some of the issues around the agenda for workforce reform as it applies to professionals who work in early years classrooms (4–7 year olds), who work alongside class teachers in supporting learning. Their changing roles, responsibilities and professional identities are examined through a small scale case study of four women, two nursery nurses and two teaching assistants, from an infants school in a suburb of Bristol. Their close professional and personal relationships with the six female class teachers with whom thery work are considered. Their stories are analysed for their significance as women whose levels of skill and dedication are undervalued in terms of career structure, salary and job security. Whilst contributing to the debates around the changing roles and the valuable work of teaching assistants, this research endorses the view that these professionals' voices are too often silenced in educational debates and in strategic decision making.  相似文献

ABSTRACT

In theory, both virtual manipulatives and explicit instruction are viable options to support students with disabilities as they learn mathematics. This study explored the effect of a treatment package—an app-based virtual manipulative (Cuisenaire® Rods) in conjunction with explicit instruction—on students’ acquisition and generalization of solving problems involving division of whole numbers with remainders. Three middle school students with disabilities participated in this multiple baseline, multiple probe across participants single case design study. Each of the students acquired the mathematical behavior of being able to solve division with remainders problems. In other words, a functional relation existed between the intervention package of explicit instruction and the Cuisenaire® Rods app-based manipulative and students’ accuracy in solving division with remainders problems. Yet, two students failed to generalize the skill without the explicit instruction and use of the app-based manipulative.  相似文献

Teachers of children aged four and five years in England (the Foundation Stage), since 2000, have been bound by the Curriculum Guidance produced by central UK Government. We were interested to learn of the responses of these teachers to this newly introduced document. We found that teachers welcomed the Foundation Stage Curriculum Guidance, not least because it recognised that there exists a valuable and separate stage in children's education. Further, the teachers were relieved that there was, within the document, the acknowledgement of the importance and value of play as integral to the educational needs of young children. The teachers indicated that the document was also beneficial in that it allowed them to return openly to what they felt to be sound Early Years practice which some had felt had been undermined by previous curriculum guidance. However, concerns remained in that not all stakeholders are yet aware of the needs of young children and of the resources necessary to meet these needs. En Angleterre, depuis 2000, les enseignants des enfants de quatre et cinq ans (phase dite de 'fondation') doivent se conformer à la Curriculum Guidance (Lignes directrices des programmes scolaires) produite par le gouvernement central du Royaume-Uni. Nous souhaitions connaître les réactions de ces enseignants face à ce nouveau document. Nous avons constaté que les enseignants accueillent favorablement la Foundation Stage Curriculum Guidance tant elle reconnaît l'existence d'une phase utile et distincte d'assimilation chez les enfants. En outre, les enseignants ont été soulagés de constater que la document reconnaît l'importance et l'utilité du jeu comme faisant partie intégrante des besoins éducatifs des jeunes écoliers. Ils ont également fait savoir qu'ils trouvent ce document utile dans la mesure où il leur permet de revenir ouvertement à des pratiques qu'ils considèrent comme étant saines pendant les premières années scolaires des enfants et qui, selon certains, avaient été amoindries par les lignes directrices des programmes scolaires précédents. Ils s'avèrent néanmoins toujours préoccupés du fait que toutes les parties prenantes ne sont pas encore conscientes des besoins des jeunes enfants et des ressources nécessaires pour les satisfaire. Desde el año 2000, en Inglaterra, los profesores de niños de la edad de 4 y 5 años (la Etapa de Fundación) han tenido que conformar con las reglas de curriculum introducidas por el gobierno central del Reino Unido. Tuvimos interes de enterarnos de las respuestas de aquellos profesores a ese documento nuevo. Encontramos que los profesores estan de acuerdo con la 'Guía de Curriculum de la Etapa de Fundación', por lo menos porque reconoció que existe una etapa válida y aparte en la educación de niños. Además estuvieron contentos que el documento reconició la importancia y validez de juegos infántiles imprescindible en el desarrollo del niño. Los profesores indicáron que el documento fue beneficioso también porque les permitió volver abiertamente a lo que sentieron que fueron 'prácticas sanas' de los años primeros que algunos de ellos pensaron que habían estado desacreditadas por las 'Guías de Curriculum' previas. No obstante quedan preocupaciónes que algunos interesados todavía no estan enterados de lo que los niños necesitan y los recursos que hacen falta.  相似文献
