Learning physics with a computer algebra system
To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations with which they are confronted. Still, many students have only a limited representation of the problems on which they are working. Therefore, an instructional approach was devised to promote students' understanding of these problems and to support them in forming associations between problem features and solution methods. The approach was based on using the computer alg
Designing integrative scripts
Scripts structure the collaborative learning process by constraining interactions, defining a sequence of activities and specifying individual roles. Scripts aim at increasing the probability that collaboration triggers knowledge generative interactions such as conflict resolution, explanation or mutual regulation. Integrative scripts are not bound to collaboration in small groups but include individual activities and class-wide activities. These pre- and poststructuring activities form the dida

Internet Scout Project
BRENDA is a comprehensive database of enzymes maintained by the Institute of Biochemistry at the University of Cologne. Scientists collect and evaluate enzyme function data from primary literature sources. The site has recently been updated with new enzymes and an entirely new search engine. Various searches can be performed, including enzyme name, organism, or EC number. Links to literature citations, two dimensional images, and other databases are included for many of the enzymes.

Science and Technology of Mental Illness
This site provides six lessons that help students understand what mental illnesses are. PET images show changes in the brain and how treatment can change activity levels and restore functioning. Case studies and other activities explore differences among illnesses, risk factors, and treatment plan goals. Students develop a brochure to inform people about mental illness.
Essential Science for Teachers: Physical Science: Session 2. The Particle Nature of Matter: Solids,
In-depth interviews with children that uncover their ideas about the topic at hand.,This segment provides an example of probing questions and phenomena used to elicit the student's ideas about motion of particles in a liquid. The student has several ideas about why the particles move including bubbles that popped, pressure, "commotion," waves, etc. but seems to lack the idea that the particles in a liquid have greater energy, hence more motion. The interviewer probes further to find out if the s

Flexible navigation for the pedagogical hypermedia design and evaluation improvement
We are working on a method, called CEPIAH, for the design and the evaluation of pedagogical hypermedia. We propose a web based system used to help teachers to design hypermedia documents and to evaluate their prototypes. Having already elaborated a methodology for the evaluation of interactive pedagogical hypermedia (EMPI), the experience and the acknowledgement we have is able to upgrade the design help. To help the designer in his instructional Web site creation we developed an interactive gui
Hitler and the Third Reich
This is a module framework. It can be viewed online or downloaded as a zip file.
As taught in Spring Semester 2010.
The Third Reich is one of the most notorious, discussed and horrific periods of our age and although it is also very well researched, still raises many questions: How could a man like Hitler gain so much power? How could a whole nation ‘fall’ for the Nazi ideology? Why the Jews ..?
In this module we will aim to deal with these and other questions about the time between 1933
Private Universe Project in Mathematics: Workshop 4: Thinking Like a Mathematician
What does a mathematician do? What does it mean to think like a mathematician? This program parallels what a mathematician does in real life with the creative thinking of students.,How a Mathematician Approaches Problems - Fern Hunt, a mathematician at the National Institute for Standards and Technology, is seen as she collaborates with colleagues to solve difficult technical problems. Using the metaphor of the childrenÂ’s game Towers of Hanoi, she explains her approach to solving problems. 15
Private Universe Project in Mathematics: Workshop 3. Inventing Notations
We learn how to foster and appreciate studentsÂ’ notations for their richness and creativity. We also look at some of the possibilities that early work in creating notation systems might open up for students as they move on toward algebra.,15 min. Pizzas in the Classroom In Englewood, New Jersey, Blanche Young, who attended the summer workshop, tries out one of the problems with her fourth-grade students. Later, she meets with Arthur Powell to discuss the lesson. 5 min. New Brunswick, New Jersey

Collaborative Learning: The Role of External Representat
This study investigates how two types of graphical representation tools influence the way in which learners use knowledge resources in two different collaboration conditions. In
addition, the study explores the extent to which learners share knowledge with respect to
individual outcomes under these different conditions. The study also analyzes the relationship between the use of knowledge resources and different types of knowledge.
The type of external representation (content-specific vs. conten

Using the World Wide Web to Build Learning Communities in K- 12
Social accounts of learning and human knowledge have led to attempts to reorganize schools as learning communities. This paper examines the utility of World Wide Web (WWW) for aiding in the construction of school-based and work-based learning communities An ordered list of interactions is provided to characterize the depth of students entry into new learning communities. Current offerings on the WWW are then surveyed in terms of these categories. Finally, proposals are advanced for enhancing the
Constructivism in the Collaboratory
Great attention has been paid recently to the capabilities of computers to provide environments in which active learners can construct their own understanding through open-ended interaction. Yet discussion of constructivist learning environments has commonly focused on the learner as an individual, learning in isolation from other learners. For example, Perkins (1991) characterizes a learning environment as being composed of five facets: information banks, symbol pads, construction kits, phenome
The Climate Visualizer: Sense-Making Through Scientific Visualization
This paper describes the design of a learning environment, called the Climate Visualizer, intended to facilitate scientific sense-making in high school classrooms by providing students the ability to craft, inspect, and annotate scientific visualizations. The theoretical background for our design presents a view of learning as acquiring and critiquing cultural practices and stresses the need for students to appropriate the social and material aspects of practice when learning an area. This is fo
