PHYS 101 is the first semester of a two-semester course in introductory physics for science majors/health career students which discusses kinematics, forces, energy and heat. The class meets for four one-hour lecture periods each week and one 2-hour lab.
Placement into MATH120 (Calculus & Analytic Geometry I M1 900 EGR 901 MTH 901) with approved and documented math placement test scores or by completing MATH111 (College Algebra) and MATH114 (Trigonometry MTM 901) with a grade of C or better.
Labs are required for this course. Each week, students are required to do a lab. All the labs are set by the instructor before the class. Each lab is composed by four different part, pre-lab questions, data taking, calculation, conclusion drawing. Each part uses about 30 minutes, and the total lab time is two hours per week. All the labs are traditional hands-on bench labs. In the laboratory experience, students are expected to use scientific methodology to formulate or evaluate questions, to make systematic observations and measurements, to interpret and analyze data, to draw conclusions, to test the given hypotheses, and to communicate the results orally or in writing. Data interpretation and error analysis uses liner list square fits to get the best results. Critical thinking, technology skills, problem solving skills, communication skills and cultural awareness are embedded in course work. Critical thinking skills are measured by rigorous homework problems including defining the problem, constructing a method for solving, and evaluating the result. Technology skills are embedded in the course, such as using computers with current software, and the tools used in making measurements, such as computer controlled photo gate to measure the time interval. Technology skills are assessed by evaluate the accuracy the lab results. Social skills are embedded in the course, such as working in team, defining roles, planning projects, developing oral or written lab reports. Students are expected to assess and to evaluate the effectiveness of team work by using a rubric. The class web page is updated every week, which provides supplemental information such as announcements, lecture notes, homework assignment, and students’ grades. Pre-lab questions, data taking, data analyzing, calculations, conclusion drawing are embedded in the face-to-face lab periods.
PHYS l0l encourages development of observation, classification, analysis, and deduction skills. A student is expected to understand the collection of data, how to formulate general laws from the data, and how to transfer a general law to a specific situation. In addition to understanding of the scientific method, the student is to understand the philosophy and logic of scientific thought by being able to work problems. The student will be gaining competence in reading and understanding scientific material, as well.

The classroom activity is a lecture-demonstration-discussion situation with an attempt to involve the student directly with the material being presented. Homework is either collected or discussed in class. Homework exercises are about 75% numerical and 25% explanation-discussion. All the homework questions are selected from the textbook. The difficult level of the homework questions are similar to the examples discussed during the lecture period. 5-minute-long quizzes are given over each chapter or main topic. There are three major hourly exams. All the quiz/exam questions are selected from the Test Bank which comes from the textbook publisher. Half of the questions are in multiple choice format, while the others are in regular format. A 5-inch formula card and calculators are allowed during the quizzes/exams. Students are expected to spend about additional 5 hours outside the class to complete the homework assignment, to finalize they weekly lab reports and to prepare their quizzes/exams.
The final grade is determined by: Final exam - 25%; major exams - 45%; laboratory - 15%; homework, quizzes, and presentations - 15%.
The grading scale is:
