Learning Domains or Bloom's Taxonomy
This website provides an explanation of Bloom's Taxonomy for the three domains of learning: cognitive, affective, and psychomotor. The cognitive domain involves knowledge and the development of intellectual skills, the affective domain deals with emotion, and the psychomotor domain includes physical movement, coordination, and use of motor-skills. This site presents a compilation of Bloom's Taxonomy in a table that divides the three domains into subdivisions, going from the simplest learning beh
Linkage Mapping a Mutation in Arabidopsis
Since Alfred Sturtevant constructed the first genetic map of a Drosophilachromosome in 1913, new mutations have been mapped using his method of linkage analysis. Determining the map position of a new mutation -- and its corresponding gene -- consists of testing for linkage with a number of previously mapped genes or DNA markers. Linkage is the principle that the closer two genes or markers are located to one another on a chromosome, the greater the chance that they will be inherited together as
Civil War Archeology: Investigating the Battles of Wilson's Creek and Pea Ridge
This site examines archeological techniques used to explore these two battle sites. These battles, fought in Missouri and Arkansas in 1861 and 1862, helped keep Missouri in the Union and set the stage for the Union to gain control of most lands west of the Mississippi by 1863.

A Holistic Approach to Teaching a Laboratory, Using Sea Urchin Development as an Example System
This exercise uses brainstorming, writing, and oral presentation techniques within the framework of a laboratory to illustrate the basic principles of early development. In groups, students learn how to identify a good model system (the sea urchin), isolate its gametes, mix some gametes from each sex, and study the ensuing processes of fertilization and development. After being introduced to the basic techniques, student groups design their own experimental approaches to further analyze these pr
A Virtual Learning Environment for Doing Business on the Internet
The power of the new Communication and Information Technologies influences human life and economy so deeply that makes all of us learners both as individuals and members of (real or virtual) learning communities and learning organisations in a learning society. Looking back at the communication and information technology history we could clearly observe that the main attention of researchers and technologists has been gradually moved from hardware to software, next - to human-computer interface,

Symba: a Framework to Support Collective Activities in an Educational Context
Symba is a Web-based framework designed to support collective activities in a learning context. It has been constructed with a double objective, (1) make students explicitly work out their organization and (2) provide tailorability features to allow the students to decide about the tools and resources they want to be accessible in order to achieve the tasks they have defined. Symba dissociates an organizational level and an activity level. The organization level allows students to organi
Crystalluria and its possible significance. A patient-control study.
The significance of crystalluria in the diagnosis and prognosis of urolithiasis remains a controversial subject in the current urological literature. In this study, in addition to the standard urolithiasis clinical and biochemical work-up,routine urine microscopy was performed to study crystals in 1 fresh and 2 stored morning urine samples from 140 urinary stone patients and 42 controls. Crystalluria was more frequently detected in patients (9.3% of the fresh samples)than in controls (2%). Stori
