METHODS OF INSTRUCTION
 Methods of instruction used to achieve student learning outcomes may include, but are not limited to:

  • Present class lectures (accompanied by demonstration of problem solving techniques where appropriate) in order to model a scientific approach to concepts and applications in chemistry.  Historical development of theories from experimental evidence will be discussed for some topics.  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 develop methods for more advanced, multi-step problem solving skills.
  • Show 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 to issues of modern society.
  • Create and assign pair and small group activities such as solving word problems, completing laboratory tasks, and drilling on equilibrium concepts in order to build skills through practice and discussion of process.
  • Assist and instruct 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. 
  • Conduct 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.
  • Invite guest lecturers to class in order to illustrate the use of basic chemistry in applications related to the guest’s career.
  • Develop and assign web-based, web-enhanced, and/or online tasks and activities such as a web quest on nuclear medicine or on-line 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 on-line) 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 intermediate level, multi-step problems, to define and use in correct context chemical vocabulary, to correctly relate equilibrium concentrations to equilibrium constant values, to draw diagrams of electrochemical cells, analyze data, and to apply chemical concepts to current topics of interest.
  • 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.
