Electronics and Communication Engineering 4.6 MINOR PROJECT WORK (Pg - 98) L T P - - 3 NOTE:- THE PROJECT MAY IDENTIFIED AT THE BEGINNING OF 4TH SEMESTER RATIONALE Realising the great importance of student exposure to world of work for his professional growth, two spells of industry oriented projects-minor and major have been included in the curriculum. It is necessary that teachers to play a pro-active role in planning and guidance of individual students for optimizing the benefits of the activity in stipulated time. Minor project work aims at exposing the students to industrial/field practices so as to have an appreciation of size, scale and type of operations; and work culture in the industries. Also the their application in solving field/industrial problems. The work done in minor project work will also prepare them in taking up problem solving at latter stage under major project work. Some of the projects are listed below which is just a guideline for selecting the minor project. Students can also select any project with the advice of his teacher. 1. Regulated power supply. 2.

MAJOR PROJECT WORK RATIONALE L T P - - 10 Major Project Work aims at developing innovative skills in the students whereby they apply in totality the knowledge and skills gained through the course work in the solution of particular problem or by undertaking a project. The individual students have different aptitudes and strengths Project work, therefore, should match the strengths of students. For this purpose, students should be asked to identify the type of project work, they would kike to execute. It is also essential that the faculty of the respective department may have a brainstorming to identify suitable project assignments for their students. The project assignment can be individual assignment or a group assignment. There should not be more than 3 students if the project assignment at least two to three months in advance. Each teacher is expected to guide the project work of 5-6 students. The project assignments may consist of : - Handing different software and Surfing internet. - Web Page Designing. - Software Development. - Networking. - Web site designing hosting and maintenance using wed designing tools. - Database Management system using oracle 8i. - Management Information System. - Developing application using Visual languages. - Developing application based on C and C++ - Developing system software using C and C++ - Developing projects related to office automation. - Developing software related to E-Commerce. - Developing Interactive applications using Java Applets etc. - Developing Internet application using Java script. A suggestive criteria for assessing student performance by the examiner is given in table below: Sr. No. 1 2 3 4 5 6 7 8 9 Performance Criteria Rating Scale Max.** marks Excellent Very Good Good Fair Poor 10 10 8 6 4 2 10 10 8 6 4 2 20 20 16 12 8 4 20 20 16 12 8 4 10 10 8 6 4 2 5 5 4 3 2 1 5 5 4 3 2 1 10 10 10 10 8 8 6 6 4 4 2 2 100 100 80 60 40 20 Selection of project assignment Planning and exaction of considerations Quality of performance Providing solution of the problems or production of final product Sense of responsibility Self expression / communication skills Interpersonal skills / human relations Report writing skills Viva voce Total marks Important Notes: 1. The criteria for evaluation of the students have been worked out for 100 maximum marks. The internal and external examiners will evaluate students separately and give marks as per the study and evaluation scheme of examination. 2. The teachers are free to evolve another criteria of assessment, depending upon the type project work. It is proposed that the institute may organize and annual exhibition of the project work done by the students and invite leading industrial organization(s) in such an exhibition. It is also proposed that two students or two projects, which are rated best, be given merit certificate at the time of annual day of the institute. It would be better if specific industries were approached for instituting such awards.
