The impact of membership of a virtual learning community on individual learning careers and professional identity     

Barbara Allan  Dina Lewis 《British journal of educational technology : journal of the Council for Educational Technology》2006,37(6):841-852

This study takes a relatively new direction in researching virtual learning communities (VLCs) as it explores the ways in which VLC membership can support lifelong learning and impact on individual learning careers and professional identities beyond the life of the community. The case study spans 4 years. The findings suggest that through the process of engaging in a VLC, individuals may change their ‘horizons of action’ leading to new learning and career trajectories. In particular, the study demonstrates how membership of a VLC supported and enabled some individuals to transform their learning careers and to make significant life changes. Other members developed their learning careers in an incremental manner that led to increased innovation and professional expertise. The findings suggest that VLCs are successful in supporting individual change and career development when they provide the ‘comfort zone’ of a secure and supportive virtual environment.  相似文献   

A Hierarchical Biology Concept Framework: A Tool for Course Design          下载免费PDF全文

Julia Khodor  Dina Gould Halme  Graham C. Walker 《CBE life sciences education》2004,3(2):111-121

A typical undergraduate biology curriculum covers a very large number of concepts and details. We describe the development of a Biology Concept Framework (BCF) as a possible way to organize this material to enhance teaching and learning. Our BCF is hierarchical, places details in context, nests related concepts, and articulates concepts that are inherently obvious to experts but often difficult for novices to grasp. Our BCF is also cross-referenced, highlighting interconnections between concepts. We have found our BCF to be a versatile tool for design, evaluation, and revision of course goals and materials. There has been a call for creating Biology Concept Inventories, multiple-choice exams that test important biology concepts, analogous to those in physics, astronomy, and chemistry. We argue that the community of researchers and educators must first reach consensus about not only what concepts are important to test, but also how the concepts should be organized and how that organization might influence teaching and learning. We think that our BCF can serve as a catalyst for community-wide discussion on organizing the vast number of concepts in biology, as a model for others to formulate their own BCFs and as a contribution toward the creation of a comprehensive BCF.  相似文献   

Evaluation of Short-Term Impact of a High School Summer Science Program on Students' Perceived Knowledge and Skills   总被引：1，自引：2，他引：1

Summer science programs held in university research facilities provide ideal opportunities for pre-college students to master new skills and renew, refresh, and enrich their interest in science. These types of programs have a positive impact on a student's understanding of the nature of science and scientific inquiry and can open a youngster's eyes to the many possible career opportunities in science. This paper describes a study of high school students enrolled in the Summer Science Academy program at the University of Rochester that investigates the program's impact on students' knowledge of laboratory skills, as well as the impact on student interest in pursuing a career in science. Students' exposure to advanced laboratory techniques and their interaction with professional scientists provided them with a very positive hands-on experience. Students who attended the program felt more confident in their ability to use sophisticated laboratory skills and that the Summer Science Academy program provided a positive influence on their performance in advanced science courses, as well as their desire to pursue a career in science.  相似文献   

The team teaching experiences of pre-service science teachers implementing PBL in elementary school     

Dina Tsybulsky 《师资教育杂志》2019,45(3):244-261

The current phenomenological-qualitative case study examined the team teaching related experiences of 17 Israeli student teachers in the context of using the project-based teaching method in the course of their pedagogical practicum module conducted in elementary schools. The focus of the study was on participants’ experiences in terms of quality and content. Data collection methods included reflective reports and in-depth interviews. Data analysis was conducted using the qualitative method for content analysis. Findings of the study indicate that during team teaching, the student teachers underwent a process of four qualitatively different experiential stages, each of which is characterised by a unique set of experiences. There was also a qualitative difference at each stage between the experiences of student teachers who emerged with an overall positive assessment and those who emerged with an overall negative assessment of team teaching. The practical implications of the findings are discussed. This research contributes to the professional literature on the team teaching of science courses, and may serve to encourage educators to implement team teaching as part of student teachers‘ practicum involving a project based, student centred methodology.  相似文献   

Intuitive Interference in Probabilistic Reasoning     

Reuven Babai  Tali Brecher  Ruth Stavy  Dina Tirosh 《International Journal of Science and Mathematics Education》2006,4(4):627-639

One theoretical framework which addresses students’ conceptions and reasoning processes in mathematics and science education is the intuitive rules theory. According to this theory, students’ reasoning is affected by intuitive rules when they solve a wide variety of conceptually non-related mathematical and scientific tasks that share some common external features. In this paper, we explore the cognitive processes related to the intuitive rule more A–more B and discuss issues related to overcoming its interference. We focused on the context of probability using a computerized “Probability Reasoning – Reaction Time Test.” We compared the accuracy and reaction times of responses that are in line with this intuitive rule to those that are counter-intuitive among high-school students. We also studied the effect of the level of mathematics instruction on participants’ responses. The results indicate that correct responses in line with the intuitive rule are more accurate and shorter than correct, counter-intuitive ones. Regarding the level of mathematics instruction, the only significant difference was in the percentage of correct responses to the counter-intuitive condition. Students with a high level of mathematics instruction had significantly more correct responses. These findings could contribute to designing innovative ways of assisting students in overcoming the interference of the intuitive rules.  相似文献   

Modeling treatment motivation in substance-abusing women with children     

Wilke DJ  Kamata A  Cash SJ 《Child abuse & neglect》2005,29(11):1313-1323

OBJECTIVES: Children are often considered a primary motivator for women seeking substance abuse treatment. This study tested a model predicting treatment motivation in substance-abusing mothers. METHODS: This study was a secondary analysis of the Drug Absue Treatment Outcome Study (DATOS). It used structural equation modeling to describe factors influencing motivation for treatment. DATOS is a national study of substance abusers entering treatment. Treatment was provided by a sampling of community-based programs, free-standing hospitals, hospital units, county-funded programs, modified therapeutic communities, and criminal justice programs. The subsample of women with children under the age of 18 for whom custody of children could be determined was selected (n=1371). The variables comprising each factor were based on self-report, and standardized scales measuring level of drug involvement, psychological functioning, children, and a desire to stop using drugs were used. RESULTS: Drug involvement was positively related to poorer psychological functioning, child custody issues, and the desire to stop using drugs. Child custody issues had a negative influence, while poorer psychological functioning and a desire to stop using drugs positively influenced treatment motivation. CONCLUSIONS: The negative influence that children have on treatment motivation may reflect the practical or emotional difficulties of having to leave children behind or in some instances having children placed in foster care. Specifically, losing custody of children, particularly with little expectation they will be reunified, may serve as a detriment to motivation. Popular beliefs hold that children serve as a primary source of a mother's treatment motivation; however this study found the opposite was true. Children should not automatically be considered a primary source of motivation for participation in treatment.  相似文献   

Intuitive nonexamples: the case of triangles     

Pessia Tsamir  Dina Tirosh  Esther Levenson 《Educational Studies in Mathematics》2008,69(2):81-95

In this paper we examine the possibility of differentiating between two types of nonexamples. The first type, intuitive nonexamples, consists of nonexamples which are intuitively accepted as such. That is, children immediately identify them as nonexamples. The second type, non-intuitive nonexamples, consists of nonexamples that bear a significant similarity to valid examples of the concept, and consequently are more often mistakenly identified as examples. We describe and discuss these notions and present a study regarding kindergarten children’s grasp of nonexamples of triangles.

Science Teachers’ Perceived Benefits of an Out‐of‐school Enrichment Programme: Identity needs and university affordances     

April L. Luehmann  Dina Markowitz 《International Journal of Science Education》2013,35(9):1133-1161

Science enrichment programmes housed outside traditional school settings offer unique opportunities to access and use authentic scientific tools and practices, especially for urban students whose school science experiences often lack resources. Yet opportunities to access these tools and practices are realized only when science teachers value them sufficiently to take advantage of them. This study examines how eight urban secondary science teachers evaluated a specific out‐of‐school science enrichment programme—a one‐year partnership with a local university science outreach centre, which culminated in a half‐day laboratory experience for their students. Teachers’ perceptions were captured through interviews and surveys. Findings indicate that these teachers came to identify and value many of the potential benefits for out‐of‐school enrichment programmes reported in the literature as well as some additional ones. The teachers’ also showed a shift over time with respect to their perceptions of the value of the out‐of‐school experience, moving from an initial focus on increasing test scores toward a greater appreciation for its impact on students’ motivation and identity development. The study offers insight into secondary science students’ and teachers’ identity needs, and what universities can offer to address them.  相似文献
