• 1 comprehensive religious school
• 1 “Ort adivi – indastrial scool
• School of arts
• School of science
• A Yeshiva, an Ulpana (religious girls’ school)
• An Academic College attended by 5,500 students
• Employs 180 teachers and 20 administration employees.
• The students arrive from all neighborhoods of Ashkelon.
• Integrated Junior school and High school
• Servers 2,000 students (1,000 in the junior school, and 1,000 in high school).

Bio-medical studies
Science And Engineering Discipline
Biomedical Engineering Activity in online environment
• Developed by ORT Israel for the Ministry of Education.
• In cooperation with the Bio-Medical engineering faculty of Ben-Gurion University.
• Under the supervision of Prof. Ofer Barnea (head of the bio-medical engineering department in Tel-Aviv University).
• Designed for students with high learning abilities in science and engineering.
• Provides skills needed in the academic field. – research– independent thinking– team work.
• On-Line environment.
Bio-medical studies Fields of studies
• Physics , Chemistry or Biology
• Engineering Sciences
• Integrated projects - Electronics - Algorithmics- Bio-Medical Engineering
• The program is based on Analogies Theory.
What is Analogies Theory ?
• Analogies are fundamental concepts, thought processes or mathematic patterns, used in a variety fields of science.
• Learning by analogies helps the student develop a broad perspective of science and technology.
What is Analogies Theory ?Examples
• Minimum energy• Magnification • Resonance • Waves• Feedback and control• Analysis of the graph gradients (derivatives) • Analysis of the area below a graph (integral)• Exponent expansion rate
Bio-medical studies On-Line environment
• Completely Interactive
• No books are required
• Teacher-Student interaction via Internet
Activity ExampleMeasuring a walking man motion,
and filtering the measurement's noise.
Required equipment:• Webcam• Internet• Excel• Videoxp (a video editing software).
Phase1:Download the instructions file.
• Phase 2: Take a video clip of a walking man.
• Phase 3: Follow the man’s movement (center and gravity) using Videoxp.
• Phase 4: save the movement data on a spreadsheet (time, location, x-axis, y-axis).
Phase 4: save the movement data on a spreadsheet (time, location, x-axis, y-axis).
Phase 5: Ignore X-axis
Phase 6: In order to reduce the ponit’s noise, calculate the average of each 3 sequential points.
Phase 7: calc the speed of center
Phase 8: calc the acceleration of the center
Phase 9: calc the effort invested in the walk.
Phase 10: calc the power
velicity and acceleration
