METHODS AND TECHNOLOGY FOR TEACHING
Engage student in active learning, contextual setting for lesson. Encouraging curiosity
constructivist principle
learning by doing, hand on minds on hearts on
Discovery principle
make students work, participation
collaborative learning
consider multiple Intelligence and learning styles
consider individual differences
challenging but not threatening atmosphere
brain based principle
brain is a parallel processor
Learning principles
traditional assessment, paper and pencil test
written exams
real world application of knowledge and skills. can be a product and/or process oriented
performance tasks
hands on activities. Active in conducting experiments, making observations, and analyzing data

mortar and pestle
designed for precise, clean, and controlled incisions
scalpel
Magnifies the image formed by the objective lens and allows the viewer to observe the specimen which have a standard magnification of 10x
eyepiece/ocular lens
collects and magnifies the light transmitted through or reflected from the specimen producing an enlarged image
objective lens
supports the specimen being observed and holds it in place for examination under the objective lens
stage
focuses an concentrates light onto the specimen, improving illumination and image clariy
condenser
controls the amount of light passing through the condenser and onto the specimen, adjusting the brightness of the image
diaphragm
moves the stage up and down rapidly to roughly focus on the specimen
coarse adjustment knob
moves the stage slightly and precisely to fine tne the focus and achieve a sharp image of the specimen
fine adjustment knob
provides support and stability to the microscpe, allowing for easy handling and transportation
arm

base
provides a light sourse, usually located at the base, that illuminates the specimen for observtaion
illuminator
holds and rotates the objective lenses, allowing the user to switch between different levels of magnification
nosepiece
secure the specimen slide in place on the stage, preventing it from moving during observation
stage clips
uses visible light and lenses to magnify and observe specimens
