It will provide an opportunity to experience the process of completing air conditioning designs in complex industrial and commercial applications. It will enable learners to interpret the air conditioning requirements of a building, develop practical air conditioning schemes for a range of environments and evaluate the effectiveness of alternative schemes. A variety of learning and teaching methods will be employed. Students will be expected to spend a total of 150 hours of study which will be apportioned as follows: 47 contact hours involving a mixture of lecture and classes. Much of the content will be directly taught through a variety of class-based activities. Lectures will be used to provide general underpinning knowledge and explain the various principles. However, emphasis is upon student-centred activities including research tasks, group work, individual tasks, presentations and demonstrations which will be organised to develop the transferable skills outlined in section D of the programme specification. IT applications will be included with workshops provided where required. Tutorials will be arranged to assist and direct the students in their work; to give feedback on coursework; to diagnose learning difficulties; and provide guidance and counselling. 40 hours – assessment & revision 63 hours – private study UNIVERSITY OF KENT – CODE OF PRACTICE FOR QUALITY ASSURANCE 16 Assessment methods and how these relate to testing achievement of the intended learning outcomes Assessment may be formative and summative and both may feature as part of the process. Although assessments must be focused on the individual achievement of each learner, group work and role-play activities may contribute to the assessment. Integrative assignments and project work will help to link this unit with other related units. Where available, evidence from the workplace can also be incorporated to enhance the learning outcomes, provided that this evidence is appropriate and authenticated as the learner’s own work. The volume of evidence required for each assessment should take into account the overall number of assessments being contemplated within this unit and the design of the overall teaching programme. Appropriate attention must be given to health, safety and welfare arrangements and CDM Regulations throughout the delivery of this unit. In designing the assessment instruments, opportunities may also be included to generate evidence to meet the CIC Common Learning Outcomes and higher level skills appropriate to the outcomes of this unit. A full range of assessment methods will provide students with a varied menu of assessment experiences. Formative methods will be used to provide maximum feedback and support to facilitate continual progress. Coursework (70%) will comprise a number of assignments to assess the competence of the skills inherent in the specific and generic learning outcomes. Verification exercises will authenticate the work carried out in the coursework assignments and an additional end examination may be included to supplement the assessment process as/if required.
