Research Areas:

Neutron Transport Theory. Nuclear Reactor Physics. Nuclear Radiation Interaction with Matter. Biological Effects of Radiation. Some Topics in Mathematical Physics. Physics Education Research

Research & Teaching Profile:

Recent: “Physics Education Research” as “implementing multimedia in teaching physics” and “improving the learning wagih researchexperience in physics education”. ROP Research Projects in “Health Physics” as “Nuclear Radiation Interaction with Matter” and “Biological Effects of Radiation”.

Teaching Strategies and Innovative Teaching Methods:

The following teaching methods (schools) are in use:

Strategy of Discussion (Socrates method): through in-class talks, posting puzzling questions or situations followed by class discussions and answers.

Strategy of Demonstrations:  a lot of demonstrations and toys are being used; some of them are being made by myself. Typical examples for the hand-made demonstrations are the roller coaster and various fluid mechanics experiments.

Strategy of Investigation/Inquiry: by encouraging the students to search by themselves and enjoy the positivity of learning by inquiry through extending their search to the internet, the library, and other sources of information.

Extensive use of animations and simulations.: what happens in class is that I follow the given link to the sited animation or simulation, display it on the screen, and start to change some variables to show the students the effect of changing certain variable on the others. In fact, these animations proved to be attractive and helping the students to grasp the ideas faster than lengthy arguments or theoretical proofs.

Clear, attractive and detailed lecture notes or Power Point slides are given and posted on the web site of the course together with many other helping facilities.
