TYPICAL METHODS OF INSTRUCTION 3 Instructors of this course might conduct the course using the following methods: Face-to-face education Lecture presentation. Small group discussions and problem solving. Online Education 1. Course content delivered in online modality and may include powerpoint presentations, video or static content. 2. Email and/or chat features may be used to allow students to address individual concerns. 3. Asynchronous discussion on relavent topics. 4. Computer or Web-based Activities 5. Timed Exams and Quizzes may also be used. For this distance-education modality, effective instructor-student contact will be established and/or maintaned as follows: 1. Email and/or chat features may be used to allow students to address individual concertns. 2. Allowing students to participate in an asynchronous discussion allows for a more open discussion and will likely increase the instructorstudent interaction. 3. The addition of Computer or Web-based Activities allows for faculty to require mastery of certain skills. Instructors are able to observe the progress of the students and can modify lecture or office hour time according to student need. Hybrid Education Option 1: Lecture portion online, lecture discussion face-to-face Option 2: Lecture portion face-to-face, lecture discussion online computer or web-based activites. 1. The addition of Computer or Web-based Activities allows for faculty to require mastery of certain skills. Instructors are able to observe the progress of the students and can modify lecture or office hour time according to student need. 2. Discussion boards/chat rooms may be used to increase student-student and instructor-student interaction. 3. Lecture material may be emphasized by adding online componenets. 5. TYPICAL ASSIGNMENTS A. Quality: Assignments require the appropriate level of critical thinking Problem solving homework and exams. Examples of homework/exam questions: 1. Given that 1 mi = 1760 yd, determine how many miles are in 1849 yd. 2. A binary compound of magnesium and nitrogen is analyzed and 1.2791 g of the compound is found to contain 0.9240 g of magnesium. When a second sample of this compound is treated with water and heated, the nitrogen is driven off as ammonia, leaving a compound that contains 60.31% magnesium and 39.69% oxygen by mass. Calculate the empirical formula of the two magnesium compounds. B. Quantity: Hours spent on assignments in addition to hours of instruction (lecture hours) Weekly problem solving homework assignments. Weekly readings from text and/or online sources. 6. TEXTS AND OTHER READINGS A.Required Texts: Basic Chemistry, 6th Edition, Zumdahl, 2007 Comments: Used for face-to-face or online course offerings. B. Other reading material: III. DESIRED LEARNING A.
