ELEMENTS OF ELECTRONICS (17215)31. APPROACH TO CURRICULUM DESIGN1.1 INTRODUCTIONMaharashtra State Board of Technical Education is an autonomous organization sinceApril 1999. The main activities of the board are to design the curricula of Diploma andpost diploma courses and conduct examinations. Further the Board develops appropriatelearning resources – print and non-print – to be used by the students. In order to ensurethe quality of education, monitoring of institutions is carried out normally two times in ayear. Teachers are the backbone of technical education system and hence efforts are madeby the board to provide training opportunities to the teachers. Presently industrial trainingis arranged for the teachers through Maharashtra Economic Development Council(MEDC). Teachers and supporting staff are also deputed for training organized byNational Institute of Technical Teachers Training and Research, Bhopal.During last five years there has been remarkable change in the industrial scenario. Theexpectations of present and future industries indicate the changed role of a diplomaengineer. It is therefore necessary to redefine the job profile of diploma engineer. Thisrevised job profile will be useful in revising the curriculum.The basic principle while designing or revising any curriculum is to identify needs of userindustries. This data and its analysis help in deciding curriculum objectives and furtherenable to select appropriate subjects.Therefore Industry Survey to identify the present and future needs of industry wasconducted in July 2011 by the committee appointed for curriculum revision.For the purpose of revising the curriculum Project Institutes were identified. A team ofCoordinators, Core group members and Subject Experts was formed to execute therevision. The team members were identified from various Government, GovernmentAided and Private Polytechnics.
ELEMENTS OF ELECTRONICS (17215)4Training in Curriculum Development of faculty members involved at various levels wasconducted. The core group members visited a number of industries to have first handknowledge about the expectations of industries from diploma pass outs. Industry expertswere involved at all the stages of curriculum revision and validation.The details related to curriculum philosophy, curriculum model, curriculum objectives,desired skills, link diagram, salient features and implementation strategy are given below1.2 CURRICULUM PHILOSOPHYMSBTE has adopted systems approach while designing the scientific based curriculumsince 1995. The same approach has been adopted while revising the curriculum insemester pattern.Fig. No. 1 shows the systems diagram. This diagram provides the holistic view forcurriculum designing, development, implementation and evaluationThe input to polytechnic education system is the students having 10+ qualifications. Theteaching learning process occurs in the institution for six/eight semesters. The output ofthe system i. e. Diploma pass out is normally the input to industries. (Some students dogo for higher education). While designing the curriculum the expectations of theindustries play a major role. Due to globalization and competition the industries expectthat pass outs have generic and technological skills along with right attitude.

To develop learning to learn skills and life skills to cope up with industrial culture6. To impart managerial skills by providing appropriate theoretical inputs7. To develop problem solving ability through technical projects.DESIRED SKILLSIndustries expect from the diploma engineer the abilities and skills of general nature andspecific to the job performance. The curriculum aims at developing life skills andtechnological skills so that the diploma pass outs would be suitable for industry. The skillsare listed below:Life Skills:Search information from various sourcesDevelop communication abilityDevelop Presentation skillWork as a member of a team/group and as leader

ELEMENTS OF ELECTRONICS (17215)91.5 Salient Changes in the curriculum:For First Semester Basic Science is divided into two parts- Basic Physics and BasicChemistry. Theory examination of both parts as well as practical examination of bothparts will be conducted on separate days. Sum of theory marks of both parts shall beconsidered for passing theory examination of Basic Science. Similarly it is applicable topractical examination. It is mandatory to appear for theory and practical examination ofboth parts. Candidate remaining absent in any examination of any section will not bedeclared successful for that exam head.For second semester Applied Science is divided into two sections- Applied Physics andApplied Chemistry where the theory examination of 50 marks each and practicalexamination of 25 Marks each will be conducted separately and the minimum passingmarks for Engineering Science will be the combination of both the sections. . It ismandatory to appear for theory and practical examination of both parts. Candidateremaining absent in any examination of any section will not be declared successful forthat exam head.The components of Development of Life Skills were taught in two semesters. InDevelopment of Life Skills –I the topics related to personal development, such asLearning to Learn Skills, personality development, presentation skills etc. were included.In Development of Life Skills – II the topics related to Team Building, Leadership, groupbehavior etc. were covered. In the revised curriculum the scope of development of lifeskills has been broaden to include behavioral science component. Therefore the subjectDevelopment of Life Skills – II has been renamed and it is now included at 5thSemesterin the revised curriculum under the title Behavioral Science.The subject of Professional Practices was introduced to integrate the skills acquired inDevelopment of Life Skills, through technical subjects from second to sixth semester.The experience in implementing the contents of the subject shows that there are limitedactivities possible in second semester as the technical knowledge given to the students isvery limited. Also at sixth semester the student are doing projects in which they areperforming many activities included in the Professional Practices and therefore it isproposed that the subject of Professional Practices be prescribed only for three semestersvis. Third, fourth and fifth semesters.
ELEMENTS OF ELECTRONICS (17215)10Introduction of Environment Engineering at fourth Semester for all coursesFrom the experience of implementation of Elective Subjects at V and VI semesters inlast five years, it is proposed to have only one elective either at the fifth and sixthsemesters for all courses. However the specialized courses like Medical Electronics,Electronics and Video Engineering will not have provision for electives. For elective,student will have to choose one from the given two/three subjects.While revising the curriculum redundant /obsolete topics/sub topics are being replacedby new/advance technology topics/sub topics.In Mechanical Engineering Group CADD, 3D Modelling, CNC Machines, EngineMaintenance (AUTO) are introduced as independent subjects.In Civil Engineering Group CAD has been added as an independent subject.In Electronics Engineering Group simulation software has been introduced, weightageof Microprocessors is reduced and more weightage is given to Microcontrollers, topicson PLC and SCADA are added, contents of discrete circuits are reduced and emphasisis given on integrated circuits.In Electrical Engineering new topic of LED lighting has been added in IlluminationEngineering subject. Similarly introduction of residential solar lighting systems, topicslike duties and responsibilities of Electrical Inspector, Commercial aspects of powerutilities have also been added. Heating, Ventilation & Air-conditioning (HVAC) hasbeen deleted from the revised curriculum. Subject of Power System Operation has beenintroduced at VI Semester Electrical Course also.
