Which Type of Inquiry Project Do High School Biology Students Prefer: Open or Guided?     

Irit Sadeh  Michal Zion 《Research in Science Education》2012,42(5):831-848

In teaching inquiry to high school students, educators differ on which method of teaching inquiry is more effective: Guided or open inquiry? This paper examines the influence of these two different inquiry learning approaches on the attitudes of Israeli high school biology students toward their inquiry project. The results showed significant differences between the two groups: Open inquiry students were more satisfied and felt they gained benefits from implementing the project to a greater extent than guided inquiry students. On the other hand, regarding documentation throughout the project, guided inquiry students believed that they conducted more documentation, as compared to their open inquiry peers. No significant differences were found regarding ??the investment of time??, but significant differences were found in the time invested and difficulties which arose concerning the different stages of the inquiry process: Open inquiry students believed they spent more time in the first stages of the project, while guided inquiry students believed they spent more time in writing the final paper. In addition, other differences were found: Open inquiry students felt more involved in their project, and felt a greater sense of cooperation with others, in comparison to guided inquiry students. These findings may help teachers who hesitate to teach open inquiry to implement this method of inquiry; or at least provide their students with the opportunity to be more involved in inquiry projects, and ultimately provide their students with more autonomy, high-order thinking, and a deeper understanding in performing science.  相似文献   

Adaptive Assistance for Learning Improvement Efforts: The Case of the Institute for Learning     

Meredith I. Honig  Gina S. Ikemoto 《Peabody Journal of Education》2013,88(3):328-363

Districts across the country face significant demands to strengthen student learning districtwide, and many are turning to intermediary organizations to help them build their capacity for such demanding, large-scale work. However, how these “learning-support intermediary organizations” assist with these capacity-building efforts is little understood. This article reports data from a largely qualitative investigation into how one such intermediary organization, the Institute for Learning (IFL) at the University of Pittsburgh, partnered with multiple urban districts to help build district capacity for districtwide learning improvements. Our conceptual framework draws on sociocultural learning theory to identify key features of the IFL-district assistance relationships that seem associated with these outcomes. We utilized data from interviews, observations, document reviews, and focus groups conducted over a five-year period. Findings elaborate specific features of their assistance relationships—which we call adaptive assistance relationships—such as enabling particular forms of modeling, tools, and opportunities for rich dialogue. We conclude with implications for the research and practice of districtwide learning improvement efforts and the participation of intermediary organizations in the process.  相似文献   

Building interfaces for on-line collaborative learning     

Ivan Kalas  Michal Winczer 《Education and Information Technologies》2006,11(3-4):371-384

For several years we have been engaged in the development and research of software environments for collaborative learning, for example in the recently completed CoLabs project (which we presented at the IFIP TC3 WG3.5 working conference in Budapest in 2004, see also http://matchsz.inf.elte.hu/Colabs/), also within lately defended long-range doctoral research, in which the co-author of this paper together with his undergraduate students had developed and evaluated cooperative computer activities for children aged 10 to 18. They observed children when using those environments and studied the influence of different approaches and solutions on the degree of their involvement and will to cooperate. We have also been involved in the London Knowledge Lab pilot project for developing a collaborative layered learning space travel games construction kit. Our department’s prior engagement in the development of collaborative activities also includes publishing a popular on-line journal (developed by A. Hrusecka and D. Lehotska, this on-line journal (in Slovak) can proudly boast up to 250,000 visits per month) for children, which intensively exploits on-line collaboration. This topic attracts us not only as a support for the learning process, but is a challenge for us as developers of educational programming tools as well. In our SuperLogo and Imagine environments we have always tried to provide users (ranging from children to developers) with new and powerful options to foster learning by exploring and developing. Thus we have equipped Imagine with the means for building objects and their behaviours in incremental loops, with parallel independent processes, event-driven programming and complex yet intuitive support for developing on-line environments for collaborative learning. In this paper we place our collaborative applications in the context of other related interfaces reported in literature. We use eight criteria to classify them and conclude that collaborative applications being developed by us and our students—future teachers—are distinguishable from others along two or three of those criteria: they combine in themselves typical features of Logo microworlds and inspiring support for on-line cooperation. We then analyze in detail our collaborative Imagine microworlds along four dimensions of their development. We specify means for establishing and maintaining on-line connection among any number of participants. We study tools for sending and receiving items (data, active characters with their behaviours, instructions etc.). We reflect on what can be shared by two or more participants in a collaborative activity. We examine all possible operations with common and private characters of a participant from the collaboration point of view. Our goals in this research and development are to:

1. Better understand potential the interfaces for on-line collaboration offer to support the learning process,
2. Place our Imagine Logo microworlds into context of other related applications,
3. Build a detailed map of all aspects important for their development (i.e., build a framework for the development),
4. Present the observations from our long-range experimental development and evaluation of the collaborative environments,
5. Point out how simple and natural it is (in the academic surroundings) to develop small and yet powerful collaborative microworlds—built for instance for immediate need in a classroom—with exceptional potential for interaction and openness.

Most of all, however, we want to motivate the endeavour to overcome all obstacles connected with the integration of on-line cooperation into children’s learning.  相似文献   

VERBAL JUSTIFICATION—IS IT A PROOF? SECONDARY SCHOOL TEACHERS’ PERCEPTIONS     

Michal Tabach  Ruthi Barkai  Pessia Tsamir  Dina Tirosh  Tommy Dreyfus  Esther Levenson 《International Journal of Science and Mathematics Education》2010,8(6):1071-1090

According to reform documents, teachers are expected to teach proofs and proving in school mathematics. Research results indicate that high school students prefer verbal proofs to other formats. We found it interesting and important to examine the position of secondary school teachers with regard to verbal proofs. Fifty high school teachers were asked to prove various elementary number theory statements, to write correct and incorrect proofs that students may use, and to evaluate given justifications to statements from elementary number theory. While all the participants provided correct proofs to the statements, our findings indicate that teachers are not aware of students’ preference for verbal justifications. Also, about half of the teachers rejected correct verbal justifications. They claimed that these justifications lacked generality and are mere examples.  相似文献   

A University Administrative Information System: Getting People Involved and Combating Doubt     

Miroslava Misáková  Michal Brandejs  Iva Hollanova  Jan Pazdziora 《Higher Education in Europe》2001,26(4):529-532

An on-line information system at Masaryk University, in the Czech Republic, has been functioning for a little more than two years. Its aim is to facilitate the management of the university and gradually to introduce state-of-the-art new information technologies into the full fabric of university life. Although the project has encountered some resistance, it has, little by little, gained acceptance as staff and students from all disciplinary areas have discovered ways in which it can make their work efficient.  相似文献   

Patterns of Close Relationships and Socioemotional and Academic Adjustment Among School‐Age Children with Learning Disabilities     

Michal Al‐Yagon  Mario Mikulincer 《Learning disabilities research & practice》2004,19(1):12-19

This study examined patterns of close relationships among school‐age children with learning disabilities (LD) as manifested in their attachment style, their self‐perceived loneliness, their sense of coherence, and teacher ratings of their academic functioning. In line with resilience theory, this study also aimed to further explore predictors of positive adjustment for children with LD. The sample comprised 98 children with LD from regular classes in four Israeli public elementary schools, and 98 non‐LD children from the same classes. Significant group differences emerged in attachment styles and adjustment. Attachment style significantly correlated with socioemotional adjustment but not with academic functioning. In addition, a subgroup of resilient children emerged among the LD children. Discussion focused on the value of attachment patterns for understanding social and emotional adjustment among school‐age children with LD.  相似文献   

Lexical inference in L2: predictive roles of vocabulary knowledge and reading skill beyond reading comprehension     

Anat Prior  Anna Goldina  Michal Shany  Esther Geva  Tami Katzir 《Reading and writing》2014,27(8):1467-1484

The current study examined the predictive roles of L2 vocabulary knowledge and L2 word reading skills in explaining individual differences in lexical inferencing in the L2. Participants were 53 Israeli high school students who emigrated from the former Soviet Union, and spoke Russian as an L1 and Hebrew as an L2. L2 vocabulary knowledge and decoding accuracy predicted L2 reading comprehension, which in turn was strongly related to lexical inferencing abilities in the L2. In addition, decoding accuracy predicted additional variance in lexical inferencing, beyond the role of reading comprehension. These findings support the idea that beginning L2 readers with more precise and efficient lexical representations demonstrate better lexical inferencing abilities, most likely due to the increased automatization of word reading, which frees up resources for higher level processing. These results suggest that lexical inferencing from text in the L2 might be limited not only by vocabulary knowledge and higher order comprehension processes, but also by basic decoding skills.  相似文献   

Hellos and How Are Yous: Predictors and Correlates of Communication Between Staff and Families During Morning Drop-Off in Child Care Centers     

Michal Perlman  Brooke A. Fletcher 《Early education and development》2013,24(4):539-557

Research Findings: The amount and quality of communication between staff and guardians in child care centers was examined using extensive naturalistic observations. Interactions between staff and more than 1,000 guardians who dropped their child off at their child care center were captured through a series of 20-s time-sampled observations. Structural quality indicators (ratios, staff education, etc.) were used to predict communication. Associations between staff–guardian communication and other aspects of quality were also examined. Results: Guardians spent an average of 63 s in their child's classroom during morning drop-off. Communication between staff and parents was limited, with staff providing child-related information to or soliciting it from approximately 15% of guardians. Out of several structural quality indicators, only greater professional development hours among staff in a classroom increased the likelihood of staff providing guardians with information about the program. Drop-off communication between staff and guardians and between staff and children was somewhat related to other measures of process quality. Practice or Policy: Results are discussed in terms of the importance of connecting families and centers, implications for rating center quality, and the accuracy of the drop-off period as parents’ lens into the quality of their child's classroom.  相似文献   

Visual and Auditory Morphological Priming in Adults With Developmental Dyslexia     

Michal Raveh  Rachel Schiff 《Scientific Studies of Reading》2013,17(3):221-252

The quality of implicit morphological knowledge in adult Hebrew readers with developmental dyslexia was investigated. The priming paradigm was used to examine whether these adults extract and represent morphemic units similarly to normal readers during online word recognition. The group with dyslexia as a whole did not exhibit priming with visual presentation as opposed to both age- and reading-level controls. Priming was absent when the prime and target words shared a morpheme and even when the prime and the target were identical. Only the students with phonological dyslexia, who exhibited relatively good performance in the orthographic judgment task, exhibited repetition priming but not morphological priming. Strong repetition and morphological priming effects were found for participants with dyslexia when the stimuli were auditory. The implications of the dissociation between visual and auditory priming for the locus of the deficit in morphological processing during word recognition are discussed.  相似文献
