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

  • Presenting class lectures, discussions and demonstrations by instructor or guest speakers in order to introduce students to principles, concepts, tools and equipment
  • Utilizing multi-media presentations to demonstrate and simulate complex concepts
  • Assigning homework that reinforces concepts presented in class lecture and gives students an opportunity to conduct research on a variety of air conditioning systems
  • Assigning small group and individual class exercises that enable students to work cooperatively as a team to solve system problems under the supervision and guidance of the instructor
  • Assigning special projects outside of class that expose students’ to environments, tools and methods not available in class.  The projects may include field trips or research projects
  • Assigning reading outside of textbook material; these may include building system descriptions, industry publications or equipment manuals
 
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:

  • Frequent quizzes and tests that enable instructor to assess students’ comprehension of key concepts and principles of refrigeration
  • Hands-on problem-solving exercises that demonstrate students’ ability to troubleshoot system problems, formulate repair strategies and apply content
  • Homework assignments that reinforce content and reflect students’ ability to conduct research
  • Final exam that assesses students’ overall comprehension of content material
  • Final applied project that demonstrates students’ proficiency in troubleshooting, repair and system design
