Air-Conditioning, Refrigeration, & Heating Technology

Transcription

1 Air-Conditioning, Refrigeration, & Heating Technology INTRODUCTION The Air Conditioning, Refrigeration, and Heating Technology program is 1,350 hours of instruction responsible for training individuals to attain an entry-level status in the HVAC/R industry. The program covers a broad range of instruction that may be found in the program outline of this master plan. An appropriate amount of time is spent in each area to thoroughly cover needed instructional material as well as to gain manipulative skills. The program utilizes both theory and practical application of material to help the students gain needed knowledge and skills. Due to the increasing complexity of systems on today's HVAC/R equipment, it is even more important to know why a procedure is done as well as how it is done. Understanding how a system functions, therefore, has an important role to play in this program of study. Each student must successfully complete written test material on theory and related topics as well as successfully demonstrate the practical application of this information in the laboratory environment. Prerequisites for this program should include a background in the sciences such as chemistry and physics on a very basic level, math in general with an emphasis on basic geometry, algebra and measuring. Computer skills are essential for navigating the internet, accessing computerized simulators, and interfacing with learning management systems. PROGRAM MISSION The mission of the Air-Conditioning, Refrigeration & Heating Technology program is to prepare students for employment in the HVAC mechanic or installer positions in the HVAC/R field. It is also designed to assist those students who wish to update present skills and cross-train in other HVAC/R areas. The program focuses on student and industry needs. Training is constantly updated by the instructor and program advisory committee to keep current with technological changes. PROGRAM PHILOSOPHY We believe that competent workers in the high-performance workplace need: 1. Skills in communications, mathematics, critical thinking, teamwork, and effective work habits. 2. Training in emerging concepts and technologies. 3. Relevant work-based learning experience. We will provide a caring atmosphere that promotes a high degree of student-faculty interaction and fosters development of business and industry partnerships. ADMISSION REQUIREMENTS To register you must meet with a counselor in the Student Services Department, located in C Building. Applicants must be at least 16 years of age and should be academically, physically, and emotionally capable of meeting the demands of the program. Applicants make initial application through the Admission Office. A minimum skills evaluation is part of the admission process. A high school diploma or GED is not required to enroll. However, it is very strongly recommended that all students complete either a high school diploma or a GED prior to program completion. The Air Conditioning, Refrigeration and Heating Technology program requires 10 th grade Math, 9 th grade Language, and 9 th grade Reading TABE levels in order to receive a certificate of completion. It is very strongly recommended that all students score not less than one grade level below required scores before enrolling in the program. Students must also take the Bennett Test of Mechanical Aptitude. Students who enroll prior business skills and/or training may be able to complete program requirements in less time than students who enter without this background. Page 1 of 31

2 When meeting with the counselor, students are required to provide two documents that confirm Florida residency status for tuition purposes. High school students who meet the requirements for career dual enrollment may register at FMIT if they have been recommended by their high school students should speak with their school counselor for details. TEST OF ADULT BASIC EDUCATION All applicants for this program take a state-mandated TABE assessment prior to enrollment (documented A.A., A.S., A.A.S., B.A., and B.S. degreed persons are exempt from this requirement). *Florida Statue exempts the following students from completing the entry-level assessment of basic academic skills: Applicants, who possess a college degree, associate in applied science or higher. Students who demonstrate readiness for public post-secondary education as stipulated by Florida Statue Students who pass a state or national industry certification or licensure exam that is aligned with the educational program of enrollment An adult student who is enrolled in a state-approved apprenticeship program Students requesting exemption from the basic skills assessment must provide documentation such as official transcripts and certificates. According to Florida Department of Education rules, students who fail all or parts of the TABE may only retest using a different TABE version after 60 documented hours of remediation in the Applied Academics for Adult Education (AAAE) lab or three months if not attending AAAE. Students may not retake the same test version for six months. We, therefore, strongly recommend that students test early, especially for licensure programs, in order to allow time for remediation and retesting should the need arise. Students who do not meet the minimum TABE scores set by the Florida Department of Education for their program must begin attending remediation classes in the AAAE lab prior to or at the time of enrollment in the program for at least one block a day and make acceptable progress as determined by the AAAE instructor. Students should meet state-mandated TABE requirements by the time they have completed the 1 st semester of the program. Students who do not meet statemandated TABE scores may not receive a certificate of completion as per Florida Department of Education rules. Applicants transferring TABE, PERT, or CPT scores from other testing centers must do so by having an official score report sent directly to the Admissions Office prior to enrollment. Scores brought in by hand will not be accepted. TABE scores are good for two years and must be valid at the time of enrollment. TABE scores that expire during continuous enrollment remain valid until the end of such enrollment. Under continuous enrollment, students must be enrolled at least 50% of one semester per school year and may miss no more than one consecutive semester. Continuous enrollment applies to attendance in a single program.

Post-secondary students with disabilities must self-identify, present documentation, required accommodations if needed, and develop a plan with their post-secondary service provider. Accommodations received in post-secondary education may differ from those received in secondary education. Accommodations change the way the student is instructed. Students with disabilities may need accommodations in such areas as instructional methods and materials, assignments and assessments, time demands and schedules, learning environment, assistive technology, and special communication systems. Documentation of the accommodations requested and services provided are maintained in a confidential file. TUITION Tuition is charged for adult students at a reasonable rate that may vary slightly from year to year and is due prior to the first day of each semester. Current fee information is available from the Admission Office. Tuition is waived for eligible Page 3 of 31

4 high school dual-enrolled students. Failure to pay all fees due at the time class begins will result in the student not being able to attend class and/or clinical. CLASS SCHEDULE Daytime certificated classes meet Monday through Friday from 8:00 A.M. until 2:30 P.M. for adult post-secondary students. This amounts to 30 hours of classroom instruction per week. Lunch breaks are 30 minutes in length. ATTENDANCE POLICY In an effort to develop appropriate work ethics, FMIT students are expected to attend all class sessions. As is expected in the workplace, when it is necessary to be absent due to illness or emergency situations, all students are to notify the instructor on or before the date of absence. The student attendance policy for each post-secondary program is consistent with industry standards. Campus attendance is kept via a computerized system. It is the responsibility of the student to log in and out in order to receive credit for class time. This allows the school to keep accurate attendance records for the actual number of hours and minutes attended. All adult students are expected to be in attendance at least 90% of their scheduled hours during each semester. Adult students failing to maintain the 90% attendance standard will not be permitted to continue in their program and may be required to sit out one full semester, unless administration approves to waive the 90% standard based on special circumstances. Absences A student who is absent for ten (10) consecutive class sessions will be withdrawn from enrollment in his/her program. A student withdrawn for absenteeism must petition administration to return. Students exhibiting a pattern of consecutive absences less than six days will be subject to dismissal as determined by a School Intervention Team. School Intervention Team meetings will be held as necessary to attempt to alleviate issues resulting in excessive absences and to counsel the student of possible alternatives and consequences. Students, who are late for class, including returning late from lunch, must clock in. Students who leave school early must notify their instructor and clock out. This time out of class is recorded as time absent and is counted against the required 90% attendance. Excessive tardies or early departures will be reported to the Student Affairs Specialist and will result in a meeting with the School Attendance Intervention Team. Adult students who know they will be out of school for an extended period of time (5 days or longer) may apply for a Leave of Absence from their program. A Leave of Absence will be granted only once during a twelve month period. STUDENTS WHO EXERCISE A LEAVE OF ABSENCE MAY HAVE TO EXTEND THEIR TIME IN THEIR PROGRAM AND PAY ADDITIONAL FEES. Leaving Campus During School Hours Students should notify their instructor when leaving campus early. This is for the safety of students and to allow the instructor to best utilize instruction resources. PLAN OF INSTRUCTIONAL PRACTICES Teaching Methods HVACR theory is taught using a hybrid of face-to-face instruction and interaction with the text material and instructor as well as computerized delivery of text, audio visual material, and assessments. Teaching aids utilizing digital presentations, DVDs, etc. are used to a great extent throughout all instruction. Practical shop experiences are designed to enhance and reinforce the theories involved as well as to develop manipulative skill and good work and safety practices. Wall charts, specification charts, and other reference materials are on constant display throughout the classroom and laboratory. Page 4 of 31

5 A great deal of equipment must be utilized for "hands-on" skill requirements. Test equipment such as multi-meters, amp meters, gauges, recovery machines are used so that the students will acquire rapport in working with such equipment and will have a basis for future troubleshooting requirements. Materials are reviewed and updated periodically to keep them as current and as relevant as possible. Safety A basic outline of safety standards and practices is covered along with a continuous implementation of safety principles. Evaluation Class performance, quizzes, tests, attendance, portfolio assessments, completion of project assignments, decision-making, work habits, and achievement of entry-level competencies, and other methods are used for evaluation. See Grading Procedures. Work-Based Activities Work-based learning activities play an integral part of the curriculum of FMIT s career-technical training programs. These activities are planned with two objectives in mind. First, the activity provides students with the opportunity to develop and apply a real world experience using the knowledge and skills attained in the program. Second, the activity provides the instructor with objective input from potential employers or customers of program graduates. Each workbased activity has a written instructional plan outlining objectives, experiences, competencies, and evaluation required during the activity. Work-based activities are program specific and may include: Unpaid in-school shop activities to provide customer service opportunities under the direct supervision of the program instructor. Unpaid job shadowing experiences that may include in-school or off campus employer-based experiences under the supervision of a qualified employer representative who is working closely with the program instructor. Paid or unpaid cooperative training experiences conducted at the employer s work location under the supervision of a qualified employer representative and under the direction of the program instructor. Cooperative Education Cooperative training is available for student and coordinated by the instructor and career specialist. Cooperative training if for students who have shown competence in program training that indicates readiness for placement in an on-the-job program. High school students participating in the cooperative job placement program must be in at least the 12 th grade. To be eligible for a cooperative education experience, students must have completed one-half of the required program hours and requirements. Student may be returned to the program for additional training if they do not function satisfactorily on the job or when the cooperative agreement is terminated at the request of the student, parent, employer, or program instructor. Veterans will be accepted into the program in accordance with the Department of Veterans Affairs approved program. Additional information regarding co-op opportunities may be obtained from the program instructor or career specialist. Job Shadowing Job shadowing experiences, or volunteer experiences, are available to students as part of their program training. These experiences are designed to give the student actual hands-on experience doing a variety of related tasks. Length and type of experiences will vary. The program instructor determines appropriateness of the experience. Additional information regarding job-shadowing experiences may be obtained from the program instructor or career specialist.
