Tardigrade Species Distribution Project: Lesson Plan
This online lesson plan was designed for students taking part in the active research project to document the distribution of a new species of tardigrade, a microscopic invertebrate animal. The project is part of a nationwide online collaborative research project. The lesson plan offers instructional procedures for teachers and lists materials and procedures for collecting, observing, and culturing tardigrades. The lesson involves collecting samples in the field, examining and classifying tartigr

Pythagoras Theorem Proof
An interactive applet and associated web page that demonstrates a graphical proof of Pythagoras' Theorem. The applet shows a right triangle that is replicated and then moved around to demonstrate the relationship between the sides. It can can be stepped through slowly to allow classroom discussion, or let to run as a movie. Useful for students who like to see things graphically as opposed to symbolically. Applet can be enlarged to full screen size for use with a classroom projector. This resourc

Area of a triangle (Coordinate Geometry)
An interactive applet and associated web page that calculate the area of a triangle using the formula method in coordinate geometry. The applet has a triangle with draggable vertices. As you drag them the triangle's area is recalculated from the vertex coordinates using the formula. The grid and coordinates can be turned on and off. The area calculation can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the scree

Perimeter of a trapezoid
A web page and interactive applet show how to compute the perimeter of a trapezoid. A trapezoid is shown that can be resized by dragging its vertices. As you drag, the perimeter is continuously recalculated. Text on the page explains that the perimeter is the sum of the sides. For those who prefer it, in a formula that is given. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference interactive geometry reference boo

Volume of a cylinder
An interactive applet and associated web page that demonstrate the volume of a cylinder. A cylinder is shown where the height and radius can both be changed by dragging. The volume is continuously recalculated as you drag. The calculations can be turned off for class discussion. The web page has the formula for the volume calculation, and a discussion about the subtle distinction between the volume of a cylinder and the volume inside the cylinder. The web page also has links to other pages defin

Relationship of area and perimeter of a triangle
An interactive applet and associated web page that show the relationship between the perimeter and area of a triangle. It shows that a triangle with a constant perimeter does NOT have a constant area. The applet has a triangle with one vertex draggable and a constant perimeter. As you drag the vertex, it is clear that the area varies, even though the perimeter is constant. Optionally, you can see the path traced by the dragged vertex and see that it forms an ellipse. A link takes you to a page w

Perimeter of a parallelogram
A web page and interactive applet show how to compute the perimeter of a parallelogram. A parallelogram is shown that can be resized by dragging its vertices. As you drag, the perimeter is continuously recalculated. Text on the page explains that the perimeter is the sum of the sides. For those who prefer it, in a formula that is given.

Equiangular Triangle
An interactive applet and associated web page that demonstrate equiangular triangles (all interior angles congruent). The applet presents an equiangular triangle where the user can drag any vertex. As the vertex is dragged, the others move automatically to keep the triangle equiangular. The angles and side lengths are updated continuously to show that the all interior angles are always congruent. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a co

The use case specification of actions in the goal oriented knowledge based learning environment
The proposed goal oriented knowledge acquisition and assessment are based on the flexible educational model and allows to implement an adaptive control of the enhanced learning process according to the requirements of student's knowledge level, his state of cognition and subject learning history. The enhanced learner knowledge model specifies how the cognition state of the user will be achieved step by step. The use case actions definition is a starting point of the specification that depends o
