METHODS OF INSTRUCTION
Methods of instruction used to achieve student learning outcomes may include, but are not limited to:
|
- Presenting class lectures (accompanied by demonstration of problem solving techniques where appropriate) in order to build a conceptual and practical basic framework in chemistry. Analogies to familiar systems will be incorporated into lectures to clarify chemical concepts and definitions for chemical vocabulary. Live demonstrations of chemical reactions or processes and/or video clips may also be incorporated to illustrate the dynamic nature of chemistry. Sample calculations will be explained to help students learn a step by step method for problem solving.
- Showing videos/films that visually illustrate chemical concepts at the atomic and molecular level using models (microscopic view) and relate them to the macroscopic world around us. These videos also show applications of the chemical concepts – including applications related to health and the environment.
- Creating and assigning pair and small group activities such as solving word problems, completing laboratory tasks, and drilling on nomenclature and Lewis dot structures in order to build skills through practice and discussion of process.
- Assisting and instructing students in accurate and precise methods of collecting and recording scientific data in order to build student laboratory skills. Demonstrate correct experimental techniques in order model laboratory procedures.
- Conducting individual conferences in order to assist students through dialog in developing a relationship between the student’s experimental results in lab and the chemical concepts that they illustrate. Individually assist students with experimental protocol as needed.
- Inviting guest lecturers to class in order to illustrate the use of basic chemistry in applications (including health and the environment).
- Developing and assigning web-based, web-enhanced, and/or online tasks and activities such as a web quest on food irradiation or online problem solving drills in order to illustrate applications to students through searching for information on the web or supporting repetitive drill to develop better problem solving techniques.

METHODS OF EVALUATION
Students will be evaluated for progress in and/or mastery of learning outcomes by methods of evaluation which may include, but are not limited to:
|
- Written reports, oral reports, or “poster session” presentations designed to apply chemistry concepts, problem solving, nomenclature, and vocabulary to a specific application.
- Homework assignments (possibly online) to provide instructor evaluation on individual areas of difficulty with problem solving and other skills.
- Quizzes and examinations (including the final examination) designed to demonstrate the ability to solve basic level problems, to define and use in correct context chemical vocabulary, to correctly convert formula to name or name to formula using the systematic naming system, to draw Lewis dot structures as a model for chemical bonding, and to respond to questions that relate chemical concepts to physical phenomena in the areas of health, the environment, and their everyday lives.
- Laboratory reports that evaluate the ability to collect and record accurate and precise data, to calculate (sometimes involving graphs) appropriate values from the data, and to answer questions that analyze the experimental results and relate them to relevant concepts.
