Synchronous and asynchronous interactions of bilingual Hispanic pre‐ and in‐service teachers in distance learning

Abstract

This study investigated differences in online written interactions of bilingual Hispanic pre‐ and in‐service teachers across two types of online discussion groups: synchronous and asynchronous. Participants were exposed to a shortened version of a wholly online special education course and participated in instructional activities as well as synchronous and asynchronous discussion groups over a six‐week period. The research used both an alternating treatment design to gather quantitative data, and interviews and questionnaires for qualitative data. The results support the contention that synchronous discussion group interactions are an important feature of successful online courses with Hispanic students.  相似文献   

“I didn’t know water could be so messy”: coteaching in elementary teacher education and the production of identity for a new teacher of science     

Christina Siry  Johaira Lara 《Cultural Studies of Science Education》2012,7(1):1-30

Through the examination of the experiences of a pre-service teacher participating in a field-based science methods course, we make evident the ways in which a combination of collaborative teaching experiences and reflexive dialogues allowed for the evolution and transformation of her identity. This teacher is Johaira Lara, the second author of this paper, and we have engaged in a cowriting approach that has created layers of writings over time, with the focus of providing evidence of her changing perceptions and understandings of teaching and learning science. We describe the ways coteaching and cogenerative dialogues provided the opportunity for Johaira to examine and reconsider her views on science teaching, and mediated the production and transformation of her identity. We offer an evolving analysis of her identity transformation related to specific aspects of the course that were pivotal for her emergence as an elementary teacher of science.  相似文献   

The effect of a structured story reading intervention,story retelling and higher order thinking for English language and literacy acquisition     

Ana M. Cruz de Quirós  Rafael Lara‐Alecio  Fuhui Tong  Beverly J. Irby 《Journal of Research in Reading》2012,35(1):87-113

The purpose of this study was to investigate the effectiveness of structured story reading intervention, Story reTelling and higher order thinking for English Language and Literacy Acquisition (STELLA), delivered to 38 Hispanic English language learners (ELL) placed in an enhanced transitional bilingual programme over 2 years from first to second grade as compared with 34 control students placed in a typical practice transitional bilingual programme during the same time period. Both treatment and comparison ELL students' retellings of two stories in Spanish and English were measured by five story elements. Findings were that (a) students receiving intervention outperformed their comparison peers in all five story elements in English and Spanish of both stories; (b) students showed stronger ability in their native language in four of five story elements; and (c) students performed at a higher level in the narrative‐informational story than a narrative story in both languages. Educational implications are discussed.  相似文献

Bypassing E-Reserves with Durable Links to Subscribed Content     

Linda Frederiksen  Joel Cummings  Lara Cummings  Diane Carroll 《Journal of Interlibrary Loan, Document Delivery & Electronic Reserve》2013,23(3):117-131

Increasingly, libraries of all types and sizes are adding electronic book (ebook) titles to their collections. A survey was used to explore the implications of ebook licensing and interlibrary loan use. Among academic libraries in the United States, a widespread preference for handling print books was found along with a need for more information about ebook interlibrary loan rights at one's own institution and a means to identify format type available from potential lending libraries.  相似文献   

Teaching the Inquiry Process Through Experimental Mathematics     

Lara Pudwell 《PRIMUS》2017,27(2):281-292

Abstract

In this paper, we discuss the Experimental Mathematics course taught at Valparaiso University since 2009. We focus on aspects of the course that facilitate students’ abilities to ask and explore their own research questions.  相似文献

Interactions between defining,explaining and classifying: the case of increasing and decreasing sequences     

Lara Alcock  Adrian Simpson 《Educational Studies in Mathematics》2017,94(1):5-19

This paper describes a study in which we investigated relationships between defining mathematical concepts — increasing and decreasing infinite sequences — explaining their meanings and classifying consistently with formal definitions. We explored the effect of defining, explaining or studying a definition on subsequent classification, and the effect of classifying on subsequent explaining and defining. We report that (1) student-generated definitions and explanations were highly variable in content and quality; (2) explicitly considering the meaning of the concept facilitated subsequent classification, and giving a personal definition or explanation had a greater effect than studying a given definition; (3) classifying before defining or explaining resulted in significantly poorer definitions and explanations. We discuss the implications of these results for the teaching of abstract pure mathematics, relating our discussion to existing work on the concept image/concept definition distinction and on working with examples.  相似文献   

Hands on what? The relative effectiveness of physical versus virtual materials in an engineering design project by middle school children   总被引：1，自引：0，他引：1  

David Klahr  Lara M. Triona  Cameron Williams 《科学教学研究杂志》2007,44(1):183-203

“Hands‐on” activities play an important, but controversial, role in early science education. In this study we attempt to clarify some of the issues surrounding the controversy by calling attention to distinctions between: (a) type of instruction (direct or discovery); (b) type of knowledge to be acquired (domain‐general or domain‐specific); and (c) type of materials that are used (physical or virtual). We then describe an empirical study that investigates the relative effectiveness of the physical–virtual dimension. In the present study, seventh and eighth grade students assembled and tested mousetrap cars with the goal of designing a car that would go the farthest. Children were assigned to four different conditions, depending on whether they manipulated physical or virtual materials, and whether they had a fixed number of cars they could construct or a fixed amount of time in which to construct them. All four conditions were equally effective in producing significant gains in learners' knowledge about causal factors, in their ability to design optimal cars, and in their confidence in their knowledge. Girls' performance, knowledge, and effort were equal to boys' in all conditions, but girls' confidence remained below boys' throughout. Given the fact that, on several different measures, children were able to learn as well with virtual as with physical materials, the inherent pragmatic advantages of virtual materials in science may make them the preferred instructional medium in many hands‐on contexts. © 2006 Wiley Periodicals, Inc.

ePortfolios and Reflective Practice for Food Science Students          下载免费PDF全文

Lara Wakeling  Peter Aldred  Rachael Hains‐Wesson 《Journal of Food Science Education》2018,17(2):52-59

The study investigated students’ perceptions and attitudes toward the use of ePortfolios for reflective practice as a learning and teaching strategy. A mixed‐method approach was applied to the study in a first‐year food science unit, at a regional Australian university. Data were generated via 3 sources, in order to provide the evidential basis for the investigation, including: a mixed method survey, access to student's exam results, and students’ ePortfolio reflections. The findings identified 3 key positive aspects. First, a variety of assessment methods was key to enhancing the overall learning of 1st‐year food science students. Second, ePortfolio reflective writing can be a key aspect for improved student engagement. Finally, structured ePortfolio sessions can help food science students consolidate knowledge, while also allowing them to encounter new ideas related to food science theory and develop technical knowledge. However, technological issues with using an ePortoflio can cloud the value of the reflective task for some students. Recommendations are made for how to better support and implement reflective practice using ePortfolios to enhance the learning of food science students.  相似文献
