Interaction and Collaboration Using an Intelligent Collaborative Learning Environment     

Robert M. Aiken  Marie-Noelle Bessagnet  Judith Israel 《Education and Information Technologies》2005,10(1-2):67-82

The goal of this research is to design and prototype an intelligent collaborative learning environment. Within this environment, we study synchronous interaction among group members (students) working on a problem/project. Students use an Intelligent Collaborative Support System (ICSS) and a shared activity space: the Tulka Whiteboard. Two main interaction spaces have been implemented: a planning-communication space and a production space. Dialogue and negotiation are supported through the ICSS permitting exchange and evaluation of free-text communication messages that are initiated by students choosing sentence openers from a menu. Using the whiteboard, a virtual room is dedicated to a group of students who share documents, annotations on documents, drawing tools, and text tools. Each group is provided a dynamic assessment of their collaborative skills based on a communication skills model.  相似文献   

Philosophy and the curriculum     

Israel Scheffler 《Science & Education》1992,1(4):385-394

This paper is reprinted from Israel Scheffler's Reason and Teaching (Bobbs-Merrill, 1973). It is the first of a number of classic paper which Science & Education will reprint in forthcoming volumes. These are being reprinted because their arguments still warrant attention and they are increasingly inaccessible to a good number of subscribers.  相似文献   

Supporting Child Welfare and Parent Involvement in Preschool Programs

This article discusses the findings from a mixed-method study examining the relationship between social resources and levels of parent involvement in state-funded preschool programs in Illinois. Using survey data from the Illinois Birth to Five Evaluation (n = 843) and interviews with ten preschool administrators who completed the survey, the study found the number of social resources provided by a program was positively associated with levels of parent involvement. The correlation analysis (r = −0.22, p = .0001) and analysis of variance (ANOVA) F(2,708) = 23.19, p = .0001 findings both demonstrated positive relationships wherein high numbers of social resources were associated with higher levels of parent involvement in programs. Administrator interviews confirmed survey findings and suggested additional influences on parent involvement levels and use of social resources in programs. Implications for supporting child welfare and policy recommendations for early childhood programs are provided.  相似文献   

Systems,transfer, and fields: Evaluating a new approach to energy instruction

Energy is a central concept in science in every discipline and also an essential player in many of the issues facing people everywhere on the globe. However, studies have shown that by the end of K-12 schooling, most students do not reach the level of understanding required to be able to use energy to make sense of a wide range of phenomena. Many researchers have questioned whether the conceptual foundations of traditional approaches to energy instruction may be responsible for students' difficulties. In response to these concerns, we developed and tested a novel approach to middle school physical science energy instruction that was informed by the recommendations of the Framework for K-12 Science Education (National Research Council, 2012a) and the Next Generation Science Standards (NGSS) (NGSS Lead States, 2013). This new approach differs substantially from more traditional approaches to energy instruction in that it does not require energy forms and it emphasizes connections between energy, systems, and fields that mediate interaction-at-a-distance. We investigated student learning during this novel approach and contrasted it with student learning within a comparable unit based on a more traditional approach to energy instruction. Our findings indicate that students who learned in the new approach outperformed students who learned in the traditional approach in every quantitative and qualitative aspect considered in this study, irrespective of their prior knowledge of energy. They developed more parsimonious knowledge networks in relation to energy that focused primarily around the concept of energy transfer. This study warrants further investigation into the value of this new approach to energy instruction in both middle and high school.  相似文献

Computed tomography‐enhanced anatomy course using enterprise visualization     

Hila May  Haim Cohen  Bahaa Medlej  Liora Kornreich  Nathan Peled  Israel Hershkovitz 《Anatomical sciences education》2013,6(5):332-341

Rapid changes in medical knowledge are forcing continuous adaptation of the basic science courses in medical schools. This article discusses a three‐year experience developing a new Computed Tomography (CT)‐based anatomy curriculum at the Sackler School of Medicine, Tel Aviv University, including describing the motivations and reasoning for the new curriculum, the CT‐based learning system itself, practical examples of visual dissections, and student assessments of the new curriculum. At the heart of this new curriculum is the emphasis on studying anatomy by navigating inside the bodies of various living individuals utilizing a CT viewer. To assess the students’ experience with the new CT‐based learning method, an anonymous questionnaire was administered at the end of the course for three consecutive academic years: 2008/2009, 2009/2010, 2010/2011. Based upon the results, modifications were made to the curriculum in the summers of 2009 and 2010. Results showed that: (1) during these three years the number of students extensively using the CT system quadrupled (from 11% to 46%); (2) students' satisfaction from radiologists involvement increased by 150%; and (3) student appreciation of the CT‐based learning method significantly increased (from 13% to 68%). It was concluded that discouraging results (mainly negative feedback from students) during the first years and a priori opposition from the teaching staff should not weaken efforts to develop new teaching methods in the field of anatomy. Incorporating a new curriculum requires time and patience. Student and staff satisfaction, along with utilization of the new system, will increase with the improvement of impeding factors.

History of the Infinitely Small and the Infinitely Large in Calculus   总被引：1，自引：0，他引：1  

Israel Kleiner 《Educational Studies in Mathematics》2001,48(2-3):137-174

The infinitely small and the infinitely large are essential in calculus. They have appeared throughout its history in various guises: infinitesimals, indivisibles, differentials, evanescent quantities, moments, infinitely large and infinitely small magnitudes, infinite sums, power series, limits, and hyperreal numbers. And they have been fundamental at both the technical and conceptual levels – as underlying tools of the subject and as its foundational underpinnings. We will consider examples of these aspects of the infinitely small and large as they unfolded in the history of calculus from the 17^th through the 20^th centuries. We will also present `didactic observations' at relevant places in the historical account. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献   

Flavor preferences conditioned with starch in rats     

Israel Ramirez 《Learning & behavior》1994,22(2):181-187

Rats were trained to associate artificial cherry or grape flavors with 1% starch suspensions. Conditioning was assessed by offering the rats a choice of the cherry versus grape flavors without starch. Conditioned preferences were moderately strong and persistent; 3 days of conditioning produced a preference that did not fully extinguish within 18 days. Food deprivation substantially increased intake of 1% starch suspension, However, the degree of preference conditioned was not influenced by the availability of food during the conditioning period; the rats that had been food deprived during training acquired as strong a preference as did those fed freely during training. The degree of preference obtained was similar in the rats given reinforcing and nonreinforcing fluids simultaneously or sequentially. Starch conditioned a slightly stronger preference than did the same concentration of glucose, even though these substances contain the same amount of calories. A statistically significant, but weak, preference was conditioned by 0.5%, but not by 0.25%, starch. It is proposed that the flavor of starch, independent of its calories, is reinforcing to rats.  相似文献
