Arteries and veins of the zebra fish
Arteries and veins are blood vessels and are part of the circulatory system. Arteries take oxygenated blood away from the heart and veins bring blood back to the heart after it has circulated through the body. The circulatory system distributes oxygen to the body and also moves around nutrients.

Voter Experiment
This resource consists of a Java applet and expository text. The applet is a simulation of the voter experiment, an interacting partile system that consists of a rectangular array of sites. At each discrete time unit, a site is chosen at random, a neighboring site is chosen, and the color of the first site is changed to that of the neighbor. The applet illustrates clustering of the colors and convergence to consensus.

Case It! Case Study Learning via Simulations of Molecular Biology Techniques
Case It! is an NSF-sponsored project to promote collaborative case-based learning in biology education worldwide. This paper describes the latest version of the Case It! simulation software (DNA gel electrophoresis, Southern blotting, and PCR). Students use these open-ended molecular biology computer simulations to analyze case studies involving genetic diseases, then discuss results with their peers at other institutions via web-based "poster sessions." They also use Case It! software to gather

ESD.04J Frameworks and Models in Engineering Systems / Engineering System Design (MIT)
This class provides an introduction to quantitative models and qualitative frameworks for studying complex engineering systems. Also taught is the art of abstracting a complex system into a model for purposes of analysis and design while dealing with complexity, emergent behavior, stochasticity, non-linearities and the requirements of many stakeholders with divergent objectives. The successful completion of the class requires a semester-long class project that deals with critical contemporary is

Animal Studies: Fish
Fish are vertebrates, meaning they have a skeletal system to support their bodies. All fish live underwater. Fish have gills to help them breathe underwater and fins to help them swim. Most fish are cold-blooded, meaning their body temperature is regulated by the surrounding water temperature.

The e-learning movement as a process of quality improvement in education
Quality in education has been regognized as an issue that should guide our efforts for improvement for many years. eLearning is the latest attempt to take advantage of developments in technology to improve learning. In this paper, we discuss the possibility of establishing a theory of elearning, the value of design patterns, and the possible scenarios of implementation by higher education institutions attempting to use new technologies in their courses of study. A survey concerning the elearning

A Grid-aware Implementation for Providing Effective Feedback to On-line Learning Groups
Constantly providing feedback to on-line learning teams is a challenging yet one of the latest and most attractive issues to influence learning experience in a positive manner. The possibility to enhance learning group’s participation by means of providing appropriate feedback is rapidly gaining popularity due to its great impact on group performance and outcomes. Indeed, by storing parameters of interaction such as participation behaviour and giving constant feedback of these parameters to the

Efficient Embedding of Information and Knowledge into CSCL Applications
This study aims to explore two crucial aspects of collaborative work and learning: the importance of enabling CSCL applications, on the one hand, to capture and structure the information generated by group activity and, on the other hand, to extract the relevant knowledge in order to provide learners and tutors with efficient awareness and support as regards collaboration. To this end, we first identify and define the main types of information generated in online group activity and then propose

Going Beyond the Problem Given: How Human Tutors Use Post-Solution Discussions to Support Transfer
Two studies investigated the role and effectiveness of post-solution, reflective dialogues in physics tutorials. The first study investigated the instructional roles of post-solution discussions, their relationship to problem-solving discussions, and features that predict learning. Seven tutors individually guided 15 students as they worked on problems in the Andes physics tutoring system. Tutors adapted the post-solution discussions to students' ability levels and their performance on the curre

Benefits of Virtual Characters in Computer Based Learning Environments: Claims and Evidence
Pedagogical theory of today gives high priority to social components of learning. Within the field of computer supported learning there are many attempts to acknowledge this. One approach involves the addition of virtual characters to electronic learning environments. Such character enhanced systems are the focus of the present article. Firstly, a systematic overview is given of pedagogical benefits that have been proposed in the literature regarding character enhancement of electronic learning
