This study examined the impact of computer simulation and supported science learning on a teacher’s understanding and conceptual knowledge of current electricity. Pre/Post tests were used to measure the teachers’ concept attainment. Overall, there was a significant and large knowledge difference effect from Pre to Post test. Two interesting interactions were observed during the data analysis. The first was the difference between Elementary and Secondary teachers. Both groups had significant gains, with large effect sizes, but the Elementary teachers (Pre-Mean = 3.70, Post-Mean = 7.51) started lower and ended higher exhibiting a significantly larger gain than the Secondary teachers (Pre-Mean = 4.96, Post-Mean = 6.71). The second interaction was the impact of gender. Both groups showed significant gains, with large effect sizes, but females (Pre-Mean = 3.90, Post-Mean = 7.21) gained significantly more than males (Pre-Mean = 5.13, Post-Mean = 7.01). These results confirm that computer simulation supported science learning can have a positive effect on concept attainment in teachers.  相似文献   

Family Child Care Providers’ Perspectives Regarding Effective Professional Development and Their Role in the Child Care System: A Qualitative Study     

Jane D. Lanigan 《Early Childhood Education Journal》2011,38(6):399-409

This study examines family child care providers’ perspectives regarding effective professional development and their role in the early learning and care system. Four focus groups were conducted annually for 3 years involving a total of 54 licensed family child care providers. Supportive social relationships emerged as an important dimension of family child care providers’ professional development experience. Providers preferred a cohort design which enabled them to establish relationships with colleagues and a long-term relationship with the same instructor. Trust and a non-judgmental atmosphere were critical to the learning environment. A collaborative approach to evaluation and assessment that focused on a small number of specific items each month supported the continuous quality improvement process better than a single annual assessment by an objective evaluator. Family child care providers valued professionalism, but viewed their services as a unique segment of the early learning and care system worthy of distinct professional development and respect. Recommendations for designing and delivering effective professional development for family child care providers are discussed.  相似文献   

Prediction assessments: Using video-based predictions to assess prospective teachers’ knowledge of students’ mathematical thinking     

Anderson Norton  Andrea McCloskey  Rick A. Hudson 《Journal of Mathematics Teacher Education》2011,14(4):305-325

In order to evaluate the effectiveness of an experimental elementary mathematics field experience course, we have designed a new assessment instrument. These video-based prediction assessments engage prospective teachers in a video analysis of a child solving mathematical tasks. The prospective teachers build a model of that child’s mathematics and then use that model to predict how the child will respond to a subsequent task. In this paper, we share data concerning the evolution and effectiveness of the instrument. Results from implementation indicate moderate to high degrees of inter-rater reliability in using the rubric to assess prospective teachers’ models and predictions. They also indicate strong correlation between participation in the experimental course and prospective teachers’ performances on the video-based prediction assessments. Such findings suggest that prediction assessments effectively evaluate the pedagogical content knowledge that we are seeking to foster among the prospective teachers.  相似文献   

Understanding student pathways in context-rich problems     

Pavlo D. Antonenko  Craig A. Ogilvie  Dale S. Niederhauser  John Jackman  Piyamart Kumsaikaew  Rahul R. Marathe  Sarah M. Ryan 《Education and Information Technologies》2011,16(4):323-342

This paper describes the ways that students’ problem-solving behaviors evolve when solving multi-faceted, context-rich problems within a web-based learning environment. During the semester, groups of two or three students worked on five physics problems that required drawing on more than one concept and, hence, could not be readily solved with simple “plug-and-chug” strategies. The problems were presented to students in a data-rich, online problem-based learning environment that tracked which information items were selected by students as they attempted to solve the problem. The students also completed a variety of tasks, like entering an initial qualitative analysis of the problem into an online form. Students were not constrained to complete these tasks in any specific order. As they gained more experience in solving context-rich physics problems, student groups showed some progression towards expert-like behavior as they completed qualitative analysis earlier and were more selective in their perusal of informational resources. However, there was room for more improvement as approximately half of the groups still completed the qualitative analysis task towards the end of the problem-solving process rather than at the beginning of the task when it would have been most useful to their work.  相似文献   

Students’ communicative behavior adaptability in CSCL environments     

Babak Abedin  Farhad Daneshgar  John D’Ambra 《Education and Information Technologies》2011,16(3):227-244

By the proliferation of online courses, the social dimension of computer supported collaborative learning (CSCL) is becoming more important than before. Research shows that communicative behavior adaptation to the computer medium is a critical issue in CSCL social relationship development. Two dominant theories in the CSCL field, social information processing theory and adaptive structuration theory, argue that individuals do not simply receive the technology passively but they adapt their behavior to increase benefits from the technology. This paper develops an instrument in order to operationalize the notion of individual’s communicative behavior adaptability in CSCL. Through an exploratory factor analysis performed on a small sample of post graduate students of an online degree in an Australian university, three factors have been unveiled: (1) individual perception of self-representation, (2) individual perception of compatibility, and (3) individual perception of the use of computer technology. Identification of these factors is expected to facilitate understanding of individuals’ social behaviors in CSCL environment, which in turn will guide the design of CSCL systems. In addition, the paper examines the relationships between the extracted factors and four environmental factors: learner’s characteristics, course characteristics, instructor characteristics, and technology characteristics. The results show that none of these characteristics strongly affect perception of self-representation or perception of the use of computer technology. On the other hand, a strong relationship was found between perception of compatibility and learner’s and course characteristics. The reliability as well as validity of the study is examined and findings are discussed. These findings will provide further insights into the design process of CSCL systems.  相似文献   

Perceptions of the learning environment and associations with cognitive achievement among gifted biology students     

Ronald D. Rita  Catherine S. Martin-Dunlop 《Learning Environments Research》2011,14(1):25-38

This study assessed the perceptions of 146 gifted and 115 non-gifted high school biology students and investigated associations between student perceptions and cognitive achievement. The What Is Happening In this Class? (WIHIC) was used to assess perceptions of actual and preferred learning environments. Data indicated that all students preferred a more favourable environment than the one that they were currently experiencing, but gifted students perceived their actual environment more positively than non-gifted students. Statistically significant associations between the actual learning environment and achievement on a standardised biology test were found for the majority of scales. Teacher Support, Investigation and Equity were all statistically significant independent predictors of student achievement, while Student Cohesiveness had a negative association with achievement. Interviews revealed that students interpreted some WIHIC items differently from how the developers had intended.  相似文献

ENGAGING SCIENCE: PRE-SERVICE PRIMARY SCHOOL TEACHERS�� NOTIONS OF ENGAGING SCIENCE LESSONS     

Douglas P. Newton  Lynn D. Newton 《International Journal of Science and Mathematics Education》2011,9(2):327-345

If children are engaged in science lessons, their learning is likely to be better and, in the long term, careers in science and technology will remain open. Given that attitudes can develop early and be difficult to change, it is important for teachers of younger children to know how to foster engagement in science. This study identified what a cohort of 79 pre-service teachers in England considered to be engaging elementary science lessons and compared their notions with teacher behaviours known to be conducive to engagement. First, all brought beliefs about how to engage children in science lessons to their training. They tended to favour children’s hands-on activity as an effective means of fostering attentive participation in learning, although many had additional ideas. Nevertheless, the means and ends of their ‘pedagogies of engagement’ tended to be simple and narrow. Trainers need to ensure that notions of engagement are wide enough to cope with a variety of teaching situations, as when hands-on experience is not feasible, effective or appropriate. At the same time, teachers will need to recognise that one approach may not suit all learners. Without this, there is the risk that they will lack the skills to engage children in science. Nevertheless, these beliefs could offer a useful starting point for trainers who wish to widen pre-service teachers’ conceptions of engagement and increase their repertoire of teaching behaviours.  相似文献   

Child sexual abuse and bulimic symptomatology: relevance of specific abuse variables     

Anderson KP  LaPorte DJ  Crawford S 《Child abuse & neglect》2000,24(11):1495-1502

OBJECTIVE: This study examined specific aspects of child sexual abuse in relation to symptom severity among hospitalized patients diagnosed with bulimia nervosa. METHOD: Participants were 45 hospitalized bulimic women who reported a history of child sexual abuse. Structured interviews were conducted in order to obtain detailed information regarding specific features of the abusive event(s). Participants also completed instruments that measured depression and eating pathology. RESULTS: There were no significant differences in severity of depression or eating disturbance among women reporting differing abusive experiences including intrafamilial versus extrafamilial abuse, abuse with or without the use of physical force, one versus multiple incidents, early abuse versus abuse occurring after age 14, contact versus noncontact abuse, disclosed versus undisclosed, and combined physical/sexual abuse versus sexual abuse alone. CONCLUSION: The specific characteristics of child sexual abuse are not related to the level of symptomatology for hospitalized bulimic patients. This study suggests that differences in the nature of the abuse may not be as important as the fact that the abuse occurred in the first place.  相似文献
