A physlet is a small single concept Java applet designed to teach physics. There is a very interesting book of physlet applications written for student use: Physlet® Physics: Interactive Illustrations, Explorations and Problems for Introductory Physics by Wolfgang Christian and Mario Belloni, Davidson College. This book and CD package furnishes students with a host of interactive, computer-based exercises and study resources that span the entire introductory physics curriculum. Using a practical yet engaging structure, Physlet® Physics presents a wide spectrum of “media-focused” critical thinking and problem-solving exercises, and provides students with an interactive visual representation of the physical phenomena they see in introductory physics textbooks. The animations and graphics provide insight missing from ordinary graphics and text.

INSTRUCTIONS & REGULATIONS 1. Using Mobile phones during lectures or exams is prohibited. Shut off your cell phone during class, any one uses mobile will be asked to leave the lecture room. 2. You are not allowed to disturb the class. If you miss the classroom the first 10 minutes you are not allowed to enter the classroom and you will be reported absent. 3. Side talks are not allowed, if you miss something or have a question, please, ask the instructor and not a student. Any student involved in side talks will be asked to leave the classroom. This is for the benefit to all students. 4. Students are expected to attend all classes, if they do not show up for more than 25% of the classes, they fail the course. There are no grades for attendance. 5. Quizzes have no make-ups, so try not to miss any. 6. Students are expected to participate actively in the class. 7. Check your e-mail regularly. 8. Be responsible for all class activities, announcements, and assignments when you miss a class. 9. Do not hesitate to see me if you have any question. 10.

DELIVERY METHOD We will use different types of teaching methods including: 1. Presentation explaining material. 2. Problem solving. 3. Discussion - actively involving students in learning by asking questions that provoke thinking and verbal response.

LEARNING RESOURCES AND MEDIA 1. In class we will use head projector to explain main concepts and definitions 2. Whiteboard will be used frequently for solving examples and problems. Learning/Teaching Strategies: To enhance the critical thinking skills, students are expected to present and explain key concepts and principles individually and in groups. Homework will be a regular part of the course which will allow students to practice for their exams. Handouts: A collection of handouts and selected practice questions from the textbook will be given to the students covering various topics highlighted in each chapter. 5

Homework and Assignments: There will be a minimum of 3 homework assignments over the course of the semester that will be graded and will be worth 10% of your grade. In addition there will a set of selected practice problems for each covered chapter that will serve as a practice to understand physical concepts covered in class. These practice problems are to be solved by the students outside the classroom individually or within a team work and will not be graded. Their solutions will be posted on blackboard. The graded homework will encompasses at least two problems for each covered chapter. Quizzes: Occasionally, pop-up quizzes will be given in class. This serves both as a tool to check your current state of knowledge. The quizzes will test material that has been covered in class and homework. There will be 4 quizzes, and the lowest two quiz grades may be dropped. How To Succeed In This Course: This is a three-credit class (excluding laboratory). The successful student typically spends 2-3 hours of concentrated effort for each hour spent in class. For a three-credit hour class this means up to nine hours per week, three hours in class and six hours outside of class, studying in groups and individually. Here are some hints to help make these hours as productive as possible: 1. Attend class! 2. Read the material to be presented before class. Don't fall behind! 3. Come prepared to ask questions regarding the difficult areas after they are covered in class. 4. Take notes and review and extend them as soon as possible after class. 5. Study the examples in the text and in class. 6. Do the homework assignments. 7. Try some other problems from the text book that are similar to the assigned ones, or the ones covered in class. 8. Re-read the sections in the text where you experience difficulties. 9. Get help from fellow students. Study groups are extremely useful! 10. See the instructor. Utilize office hours, email, etc. 11. Spend at least nine hours a week in concentrated effort, both in and out of class. 12. Relax, we all learn one step at a time. Using blackboard Blackboard is course software that is used in web-based academic courses. You will be using the course blackboard site to find, Course Announcements, Lecture Notes, Course related documents, Syllabus, Course Calendar, Grades, and other materials for the course. You will also be contributing to course discussions using the discussion forums and/or uploading assignments to the digital drop box.

ACADEMIC HONESTY: Academic honesty is expected of all students. It is based on the principle that one's work is one's own. Therefore, cheating, plagiarism, or any other violations of the academic honesty will not be tolerated. Cases of academic dishonesty will be dealt with seriously and may result in severe penalties, including failing the examination/assignment and possibly failing the course. Examples of academic dishonesty include: 6

   

Receiving or providing unauthorized assistance on examinations. Using unauthorized materials during an examination. Plagiarism - using materials from sources without citations (presenting work as your own when it is not). Fabricating data or references.

STUDENT WITH DISABILITIES If a student has special needs because of psychological or medical disabilities s/he has to contact me so appropriate arrangements will be made according to QU regulations.

STUDENT COMPLAINTS POLICY: Students at Qatar University have the right to pursue complaints related to faculty, staff, and other students. The nature of the complaints may be either academic or non-academic. For more information about the policy and processes related to this policy, you may refer to the students’ handbook.
