Decision Trees Video Tutorial
Learning is the ability to improve one's behaviour based on experience and represents an essential element of computational intelligence. Decision trees are a simple yet successful technique for supervised classification learning. This tool demonstrates how to build a decision tree using a training data set and then use the tree to classify unseen examples in a test data set.
Virtual Maths, Cylinder Voids - Calculating volume
Interactive simulation with exercises and video demonstrating the use of auger piling and showing how to calculate the volume of cocrete needed to fill the cylindrical voids.
Comprehension of emotion in neurodegenerative disorders
Recent evidence indicates that the posterior corpus callosum is smaller in patients with Alzheimer's disease (AD). Conversely, it has been demonstrated that patients with frontal systems deficits also have degradation of the anterior corpus callosum. Although these investigations indicate possible morphological relationships between the corpus callosum and cortical structures in neurodegenerative disorders, the relationship between specific neuropsychological measure of cognitive functioning and

27 Sep 2010: Energy Market Consequences of an Emerging U.S. Carbon Management Policy
Emerging energy and climate policies in the United States are accelerating the pace of technological changes and prompting calls for alternative energy and stricter energy efficiency measures. These trends raise questions about the future demand for fossil fuels, such that some energy-producing nations are reluctant to invest heavily in the expansion of production capacity. The abundance of shale gas resources in North America could allow the United States to utilize more gas in its energy mix a

Favoriser lintérêt des filles pour la génétique par linvestigation
Depuis plusieurs années, il a été remarqué un désintérêt des jeunes en général, et en particulier des filles, pour les sciences. Cet état de fait est un des critère pris en compte pour concevoir une séquence denseignement visant lapprentissage de la structure de lADN et la notion de mutations, en classe de seconde. La séquence sera développée dans le cadre du projet européen SCY (Science Created by You), dont lobjectif est de créer des situations dinvestigations suppor
Exploring Individual and Collaborative Dimensions of Knowledge Building in an Online Learning Commun
An exploratory study of students' engagement in online learning and knowledge building is presented in this paper. Learning in an online community, composed of students (pre-service teachers) and experts (experienced in-service schoolteachers and academics), is the study's primary focus. Students' interaction and knowledge discourse structures, arising from individual readings of academic papers and asynchronous collaboration with peers and experts, are investigated using social network and cont
Semantic Annotation for Learning Material
This paper aims at providing the specification for semantic annotation tools for e-learning. From the specific requirements of annotating learning material, we categorize and evaluate the existing annotation tools, mainly general purpose ones. We illustrate two research prototypes of annotation tools we developed, and evaluate to what extend the specific requirements of annotating learning material are reached by these research prototypes.
Group Reflection in Action
A group of students talking to each other about their experience of reflecting on their own learning.
Middle School Portal: Math and Science Pathways (MSP2)
New from The Biology Project of the University of Arizona, this online tutorial introduces the dynamic complexes of proteins, carbohydrates, and lipids that comprise cell membranes, and relates how membranes are important for regulating ion and molecular traffic flow between cells. Each section of this Web site takes the form of a multiple choice question. Answer the question correctly, and a brief explanation of each answer choice will be displayed. Answer the question incorrectly, and a short

Although a great deal of emphasis of the course is on the structures of the organs and tissues, this is not a course based solely on pure microscopic descriptions. Lectures and laboratory sessions will focus on the integration of structures with functions, drawing from many disciplines (light/electron microscopy, cell biology, biochemistry, physiology etc.). Highlights of the course are its magnificently detailed collections of tissues as represented in the Circulatory Lecture.

Interactive Concepts in Biochemistry is a nicely designed companion website to Dr. Rodney Boyer's _Concepts in Biochemistry, second edition_. Developed collaboratively by Science Technologies and others, this multimedia site is archived on the Wiley Publishers website. Site visitors will enjoy exploring the engaging and instructive collection of Interactive Animations. The collection includes Animations about DNA Replication, Signal Transduction, Photosynthesis, Cell Structure, Protein Synthesis
Internet Scout Project
The companion Web site to the NOVA program Life's Greatest Miracle, which PBS will re-broadcast on February 26th, is a great site for anyone interested in human pregnancy and fetal development. With wide-ranging information, this Web site is likely to appeal to many different audiences; users can even choose to view the entire program online. Those users interested mainly in the science of human development will enjoy How Cells Divide and How Sex is Determined. Those more interested in learning
Bend, Twist and Break: Breaking Glass
Dr. Chris Muhlstein explains that researchers learn about the scientific basis for failure of materials by running experiments in the lab, using a simple shape like a glass rod to calculate the strength of material and predict its failure. The same tests can be done at the micro and nano scale using tiny specimens. Students can run a similar experiment with a bar of chocolate.
This learning object covers the topic of clinical utility of genetic information. The object focuses on genetic information associated with colorectal cancer.
