A Case Study of Implementing an International Baccalaureate Middle Years Programme: Teachers' Motiva
The International Baccalaureate Middle Years Programme (IB MYP) is a highly competitive and rigorous review process of a middle school curriculum that, if successful, results in the school’s acceptance in an international form of accreditation. The purpose of this qualitative case study was to explore the factors influencing teachers’ motivation and their perceptions towards change in initiating and implementing a new program called the International Baccalaureate Middle Years Programme (IB
Can You Hear it?
In the previous lesson, students learned about the issue of by-catching by fisheries and how it affects marine habitats. Dolphins are one of the main species affected by by-catching While dolphins can use echolocation to identify the location of many objects, they have difficulty identifying nets, and thus can be caught in them by accident. Students will learn how echolocation works, why certain animals use it to determine the size, shape, and distance of objects, and how humans can potentially
Processing and Transforming Collaborative Learning Protocols for Learner's Reflection and Tutor's Ev
This paper discusses the potential of processing and analysis of collaborative learning protocols, which in the first place are represented as low-level logfiles of actions in collaborative learning environments. These protocols can be abstracted, analysed, and augmented to provide the users with feedback about the collaboration process. We present several techniques we implemented which may be combined to support learner s self-reflection as well as tutors in evaluating the process.
Dialectics for collective activities: an approach to virtual campus design
This contribution is an attempt to systematise our approach to the design of a virtual campus. Activities in the recently started TECFA virtual campus rely on Internet tools, but they concern both distance teaching and presential interactions. Designing learning activities is relatively easy when the learning goal is an activity in itself. In this contribution, we explain how we extend the learning by doing approach to the acquisition of declarative knowledge. After fulfilling a pseudo-task,
Judaism: The Holocaust
This video shows an interview to Mr. Kiegelman. He talks about the events in his hometown in Poland. He explains how his family moved to America in the eve to WWII and what happened to his town and to the Jews living there after 1938.
Promoting Self-Directed Learning in Simulation Based Discovery Learning Environments Through Intell
Providing learners with computer-generated feedback on their learning process in simulation-based discovery environments cannot be based on a detailed model of the learning process due to the "open" character of discovery learning. This paper describes a method for generating adaptive feedback for discovery learning based on an "opportunistic" learning model that takes the current hypothesis of the learner and the experiments performed to test this hypothesis as input. The method was applied in
Sequence effects in solving knowledge-rich problems: The ambiguous role of surface similarities
Sequence effects are said to occur whenever the problem solving performance varies as a function of the order in which problems are solved. We present a framework that explain sequence effects as a result of (a) learning during solving a problem and of (b) transferring the learned content on succeeding problems. In two experiments we studied the ambiguous influence of surface similarities among structurally dissimilar knowledge-rich problems on sequence effects. These experiments demonstrate tha
When less is sometimes more: Optimal learning conditions are required for schema acquisition from mu
While it is usually claimed that multiple examples for the illustration of problem categories are a necessary prerequisite for schema acquisition, there is a lack of conclusive empirical evidence supporting this claim. Moreover, there are findings indicating that carefully designed one-example conditions may allow for profitable processes of example comparison as well. In line with this reasoning, we present an experiment that builds up on a series of studies conducted by Quilici and Mayer (1
Using e-mail to support reflective narration
This article presents an exploratory study of e-mail use for reflective narration. Narration is viewed from three perspectives: the narrating act, the narrative statement, and the story. These perspectives are used to characterize the 69 e-mails that were exchanged between 13 groups of children from three primary schools. The findings show that e-mail narration has monologic and dialogic qualities, and leads to cognitive and personal reflections on the learning task. We conclude that e-mail can
Internet Scout Project
Plagiarism.org is an "online resource for educators concerned with the growing problem of Internet plagiarism." The organization provides information on online plagiarism and explains how Turnitin.com can be used by educators "to fight plagiarism and help bring academic integrity back into our schools." The technologies behind Turnitin.com, facts about Internet plagiarism, and the growth of "cheatsites" online are also explained. Members of Turnitin.com pay for access to "a proprietary system th
Internet Scout Project
The Atlas of Genetics and Cytogenetics in Oncology and Haematology, a peer-reviewed online journal and database provided by Infobiogen, is "devoted to genes, cytogenetics, and clinical entities in cancer, and cancer-prone diseases." Users can search the materials by genes, leukaemias, solid tumors, cancer prone diseases, and chromosomes. Researchers can find links to scientific societies and meetings. Students can explore educational materials on Mendelian and non-Mendelian Inheritance, chromoso
Internet Scout Project
Environmental Health Sciences, a nonprofit organization founded by the grassroots Virginia Organizing Project (VOP) in 2002 to help increase public understanding of emerging scientific links between environmental exposure and human health, tracks a broad range of relevant information on this well-designed and useful website. The In the News section of the homepage lists breaking news stories from the world press about environmental health and is updated daily. The New Science area offers paragra
The LEAP Authoring Tool: Supporting complex courseware authoring through reuse, rapid prototyping, a
An important goal of current work in computer-based learning environments is to develop systems that combine the richness and effectiveness of an individually crafted intelligent tutoring system (ITS) with the generality and flexibility of a computer-assisted instruction (CAI) authoring tool. Our effort to achieve this goal is demonstrated in the Learn, Explore and Practice (LEAPsm) ITS shell and its courseware development component, The LEAP Authoring Tool (LAT). The LAT was developed for use b
Internet Scout Project
This website presents the American Chemical Society's (ACS) Young Chemists Committee (YCC), which is described as "the definitive resource for chemists under 35." With the goal of connecting, encouraging, and empowering young chemists; the website offers information on an abundance of award opportunities presented by the ACS, YCC, and private and government establishments. Chemists can learn about upcoming regional and local section meetings. By downloading archives of the YCC biannual newslette
Phases of the moon
Young children may have the idea that the moon actually changes shape. This lesson explains that this apparent change is a result of the moon's revolution around the earth.
On the Cognitive Prerequisites of Learning Computer Programming
Training in computer literacy of some form, much of which will consist of training in computer programming, is likely to involve $3 billion of the $14 billion to be spent on personal computers by 1986 (Harmon, 1983). Who will do the training? "hardware and software manufacturers, management consultants, -retailers, independent computer instruction centers, corporations' in-house training programs, public and private schools and universities, and a variety of consultants1' (-ibid. , p. 27).
