Une typologie des fonctions des modèles formels : l'exemple de la biologie
Une typologie des fonctions des modèles est construite à partir d’un cadre théorique (Nifle) permettant de définir le rapport entre modèle et expérience. Il est admis qu’il existe un lien entre la manière dont on modélise en tant qu’expert ou chercheur et la manière dont on apprend à modéliser en tant qu’étudiant, et que ce lien repose sur le rapport expérience/modèle. La typologie est construite pour le cas particulier des modèles formels (utilisant un formalisme mathématiqu
Essential Science for Teachers: Physical Science: Session 2. The Particle Nature of Matter: Solids,
What simple idea links together all of chemistry and physics? How can a close study of the macroscopic differences among solids, liquids, and gases support a microscopic model of tiny, discrete, and constantly moving particles? In this session, participants learn how the "particle model" can be turned into a powerful tool for generating predictions about the behavior of matter under a wide range of conditions.,The segment provides examples of probing questions to find out if the student recogniz
College Lesson Study Project
The process of Lesson Study is a unique form of collaborative classroom inquiry, frequently practiced in Japanese elementary schools, in which a small team of instructors designs, teaches, studies and refines a single class lesson.
Faut-il vraiment laisser le déroulement d'une animation sous le contrôle de l'apprenant ?
Grâce aux possibilités technologiques accrues, l'utilisation d'animations dans les documents multimédia à visée technique ou didactique, est devenue un usage courant. Cependant, les études qui ont comparé « toute chose égales par ailleurs » animations et graphiques statiques montrent que le bénéfices des graphiques animés, loin d'être automatique, dépend des dispositifs d'interaction mis à la disposition des utilisateurs. Sur la base de la littérature, nous proposons que l'usage
Réduire l'écart entre formations théorique et pratique en chirurgie : conception d'un EIAH
L'objet de la recherche présentée est de concevoir un environnement informatique d'apprentissage qui permette de réduire l'écart entre la formation théorique des chirurgiens et leur formation pratique, qui se déroule principalement sur le mode du compagnonnage. L'article expose la méthodologie et quelques illustrations du travail didactique d'analyse des connaissances et du système d'enseignement / apprentissage en milieu hospitalier (chirurgie orthopédique). La prise en compte dans l'E
Unix Tutorial
A self-study workshop to review and/or learn a wide range of Unix tools, including shell scripts, awk, lex, yacc, grep etc. This course did not give grades. It was strictly pass or incomplete.
Statistics
This course introduces students to the basic concepts, logic, and issues involved in statistical reasoning. Major topics include exploratory data analysis, an introduction to research methods, probability, and statistical inference. The objectives of this course are to give students confidence in manipulating and drawing conclusions from data and provide them with a critical framework for evaluating study designs and results. An important feature of the course is the use of an intelligent tutori
Respiratory System 1 from the course General Human Anatomy
General Human Anatomy - Fall 2006. The functional anatomy of the human body as revealed by gross and microscopic examination.
Biology
This introductory course in "Modern Biology" covers topics found in the fields of cellular biology, molecular biology, biochemistry, and genetics. It does not cover organismal biology or taxonomy. This course is a requirement for biology majors at Carnegie Mellon University. The course is carefully planned to provide the background biology students will need for advanced biology classes. Non-biology majors will also find this course useful as it explains many of the concepts and techniques curre
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 m

Private Universe Project in Mathematics: Workshop 2. Are You Convinced?
Proof making is one of the key ideas in mathematics. Looking at teachers and students grappling with the same probability problem, we see how two kinds of proof—proof by cases and proof by induction—naturally grow out of the need to justify and convince others.,25 min. Englewood, New Jersey—Teachers Workshop Englewood, a town with unsatisfactory student test scores, is implementing a long-term project to improve math achievement. As part of a professional development workshop designed in part
Fostering collaborative knowledge construction with visualization tools
This study investigates to what extent collaborative knowledge construction can be fostered by providing students with visualization tools as structural support.
Thirty-two students of Educational Psychology took part in the study. The students were subdivided into dyads and asked to solve a case problem of their learning domain under one of two conditions: 1) with content-specific visualization 2) with content-unspecific visualization. Results show that by being provided with a content-specific

One of the strands of the Rutgers long-term study was to find out how useful ideas spread through a community of learners and evolve over time. Here, the focus is on the teacher’s role in fostering thoughtful mathematics.,Englewood—Second Grade: Probing Student Thinking. How can a teacher know what an individual student is thinking when there are 24 or more students in the room? In Englewood, a second-grade teacher tries to follow her students’ thinking by asking appropriate questions as she

Making sens: science education networks of sensors
A small group of leaders from research, industry, and education convened in a one-day workshop at Stanford's Center for Innovations in Learning (SCIL) to brainstorm on the use of data probes, sensors, and communication technologies in the development of innovative science education curricula. This report documents the results of a morning brainstorm and afternoon group exercises developing educational scenarios for which sensor networks would be powerful in enhancing learning content and promoti
