Four spheres of knowledge required: an international study of the professional development of literacy/English teacher educators

This paper reports on a research study of 28 literacy teacher educators (LTE) in four countries: Canada, the USA, England and Australia. It identifies three main forms of professional development: informal, formal and communities of practice and four spheres of knowledge: research; pedagogy of higher education; literacy and literacy teaching; and current school district and government initiatives. The study reveals the sheer scale of knowledge required to be an effective LTE and demonstrates how participants used the three forms of professional development to enhance their knowledge in each sphere. It concludes that the professional development of teacher educators is not conducted systematically; rather, it is quite ad hoc with much of it occurring through learning while doing. All had to construct their own programmes for professional development, which added yet another layer to their responsibilities.     

Development of an Augmented Reality Game to Teach Abstract Concepts in Food Chemistry

One of the most pressing issues for many land grant institutions is the ever increasing cost to build and operate wet chemistry laboratories. A partial solution is to develop computer‐based teaching modules that take advantage of animation, web‐based or off‐campus learning experiences directed at engaging students’ creative experiences. We used the learning objectives of one of the most difficult topics in food chemistry, enzyme kinetics, to test this concept. Students are apprehensive of this subject and often criticize the staid instructional methods typically used in teaching this material. As a result, students do not acquire a useful background in this important subject. To rectify these issues, we developed an interactive augmented reality application to teach the basic concepts of enzyme kinetics in the context of an interactive search that took students to several locations on campus where they were able to gather raw materials and view videos that taught the basics of enzyme kinetics as applied to the production of high fructose corn syrup (HFCS). The students needed this background to prepare for a mock interview with an HFCS manufacturer. Students and instructors alike found the game to be preferable to sitting in a classroom listening to, or giving, a PowerPoint presentation. We feel that this use of gaming technology to teach difficult, abstract concepts may be a breakthrough in food science education and help alleviate the drain on administrative budgets from multiple wet labs.     

Schedule-induced behavior in rats: Pellets versus powder

Food-deprived rats develop polydipsia on an intermittent schedule (fixed time 60 sec) of food pellet delivery, but not on an identical schedule of food powder delivery. This result was demonstrated with separate groups receiving each type of food and was replicated using rats as their own controls. Powdered food not only prevented the development of polydipsia, but it abruptly terminated ongoing polydipsia in rats that were switched from the scheduled delivery of pellets to powder. Ethological analysis of the behavior showed that the rats receiving powder were not engaging excessively in some behavior other than drinking. After discounting several factors, we concluded that the amount of oral activity associated with feeding, which occurred immediately after food delivery, was reciprocally related to the level of drinking.     

The internship component of a teacher education program: Opportunities for learning

Abstract

Many preservice teacher education programs in recent years have increased the amount of time student teachers spend in field placements by adding an “internship “ component. An internship is typically longer than a practice teaching session and is designed as a bridge between being a student teacher and having full teaching responsibilities. This study explored the effect of an internship that had three key features: the interns were free to choose the nature of their field experience, no formal evaluation was involved, and the interns were attached to the school (or other institution) as a whole rather than a particular staff member. Under these conditions, the interns could (a) go more deeply into a specific teaching area; (b) gain greater knowledge of school culture; (c) become more familiar with school‐wide programs and activities; and (d) learn more about their distinctive interests and abilities as teachers.     

Adapting Strategies of Effective Instruction for Culturally Diverse Preschoolers

This article describes collaboration between preschool and university educators focused on adapting the Center for Research on Education, Diversity, and Excellence (CREDE) standards for Effective Pedagogy for use in early childhood (EC) settings. The CREDE standards are strategies of best practices for culturally diverse K–12 students. Teachers and teacher educators worked together to adapt the CREDE standards for use with young children. Participants included 13 preschool teachers and 2 administrators serving 2- to 5-years-olds at a university-based EC center. Data sources included participant observations and video-recordings of the teachers' instruction. Criteria for measuring use of the standards were changed to be more developmentally appropriate, including adjustments for language development and a focus on goals that included self-management and social skills. The adapted CREDE EC standards may provide a useful framework for high-quality EC instruction for diverse children. This partnership may have been successful because the project drew on the strengths of both the university and EC collaborators, minimizing the hierarchical relationship that is often experienced in such an arrangement.
