Essential Science for Teachers: Life Science: Session 4. Plant Life Cycles
What is a plant? One distinguishing feature of members of the Plant Kingdom is their life cycle. In this session, flowering plants serve as examples for studying the plant life cycle by considering the roles of seeds, flowers, and fruits. A comparison to animal life cycles reveals some surprising similarities and intriguing differences.,Children's ideas about seed are discussed, with references to BSCS TRACKS. Children are about 7/8 years old. They soak lima beans and see the plant embryos. A
Essential Science for Teachers: Life Science: Session 2. Classifying Living Things
How can we make sense of the living world? During this session, a systematic approach to biological classification is introduced as a starting point for understanding the nature of the remarkable diversity of life on Earth.,This segment deals with the "other" organisms that do not easily fall into the plant or animal category. 7 year olds talk about a third ring to the Venn diagram and that bacteria would be an "other".
Verbal and Nonverbal communication in computer mediated settings
The paper discusses the verbal and nonverbal communication during a video-recorded meeting between two physically separate teams as part of a 9 month multi-site construction project. In the extract analysed here, the team which was video-recorded contained three members and the project coordinator, whereas the remote team contained a single individual. Communication between the two teams was by means of telephone and shared computer meeting system. The video-recorded team used nonverbal communic
Internet Scout Project
An entire site devoted to the Horseshoe Crab? The Ecological Research and Development Group (ERDG) has a "commitment to protect this remarkable mariner who plays a vital role in nature's delicately balanced food web and whose life-sustaining contributions to humanity have yet to be fully realized." This well-designed site gives descriptions of the Horseshoe Crab's natural history, evolution, anatomy, medical uses, conservation, research, and even a section devoted to poems, tales, and images.
Lets us look over the shoulders of scientists and glimpse the often-unseen moments of investigation. Take virtual field trips to eight observatories -- Arecibo, where astrobiologists search for signs of life beyond the solar system; Las Cuevas, a research station in Central America's largest remaining rainforest; and others. See interviews, photos, and broadcasts that explore the origins of matter, the universe, and life itself.
Toward a Web based environment for Evaluation and Design of Pedagogical Hypermedia
In order to guide and help the educational Web sites authors in the conception/evaluation process of their prototypes, it is especially interesting to propose them interactive guides. Among the existent interactive guides, only few offer a good content structure or an appropriate navigation in their system. We propose a web based system used to help teachers to design multimedia documents and to evaluate their prototypes. Our current research objectives are to create a methodology to sustain the
Looking at Learning...Again, Part 1: Workshop 8. The International Picture
This workshop offers an opportunity to investigate various aspects of the Third International Mathematics and Science Study (TIMSS), other than the test scores themselves. Distinguished Professor of Educational Psychology William Schmidt presents differences in curricula, textbooks, and teaching practices around the world, and a group of community members discuss how the TIMSS results reflect societal and cultural values.,Dr. William Schmidt speaks about assessments and the nature of testing.

Détermination automatique des théorèmes-en-acte des élèves en algèbre. Le cas des équations e
Dans cet article, nous sommes intéressés à la détermination automatique de théorèmes-en-acte en algèbre. Ces théorèmes-en-acte ont été construits de façon abstraite, puis nous avons cherché à automatiser le mécanisme de leur diagnostic. Pour cela, nous avons utilisé le logiciel Aplusix comme support des productions des élèves qui permet d'enregistrer toutes les actions des élèves. Une base de règles correctes et erronées a été mise en place et un interpréteur de règles
Software Engineering for Web Applications
Teaches basics of designing a dynamic web site with a database back end, including scripting languages, cookies, SQL, and HTML with the goal of building such a site as the main (group) project Emphasizes computer-human interface and the graphical display of information. Crucial to the project is the identification of a client with whom the group must work with throughout the month, designing specifications, implementing them, reviewing and evaluating, and testing. This is a real-life client who
Family Group Seated in their Yard
One woman and three young girls wearing white dresses are seated outside in a yard. In the background part of the house and trees can be seen. There is also an older man and woman seated on a wooden glider watching the photographer.
This curriculum covers all of the material outlined by the College Board as necessary to prepare students to pass the AP Biology exam. This course is designed to acquaint you with the general concepts of life including reproduction, balance in nature, and the nature of living things. You will focus on three broad sections that align with the goals for the AP exam: Molecules and Cells, Heredity and Evolution, and Organisms and Populations.
Sustainable Development Education
Provides models, curricula, and professional development materials for learning about managing trade-offs between resource use and quality of life. Software is offered to help clarify key principles of sustainable thinking, including a spatial modeling and visualization tool for community design and an ecological footprint calculator.
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.,Revisiting Problems After Five Years - Kenilworth 10th graders re-examine the same problem they had last seen in the fifth gradethe Pizza problem. One student, Michael, uses the binary number system to his advantage.
Supporting CSCL with Automatic Corpus Analysis Technology
Process analyses are becoming more and more standard in research on computer-supported collaborative learning. This paper presents the rational as well as results of an evaluation of a tool called TagHelper, designed for streamlining the process of multi-dimensional analysis of the collaborative learning process. In comparison with a hand-coded corpus coded with a 7 dimensional coding scheme, TagHelper is able to achieve an acceptable level of agreement (Cohen's Kappa of .7 or more) along 6 out
Transformative communication as a cultural tool for guiding inquiry science
Inquiry-based science instruction offers great promise as a means of actively engaging students in authentic scientific problem solving, including consideration of research design issues. At the same time, inquiry introduces some difficulties. In particular, familiar "cultural tools" for classroom discourse, such as Initiation-Reply-Evaluation sequences, are no longer appropriate because they are premised on known answers and teacher-driven activity. To help support productive open-ended science
Word Closets give students an additional classroom resource for "researching" the correct spelling of words to use in their daily writing. Word Closets are particularly focused toward concept words, season words, and favorite words that students like to use in their writing but may need help with spelling.
