Note:

1. A suggestive list of PrOs is given in the above table. More such PrOs can be added to attain the COs and competency. A judicial mix of minimum 12 or more practical need to be performed, all practicals are compulsory, so that the student reaches the ‘Precision Level of Daves Psychomotor Domain Taxonomy as generally required by the industry.
2. The Process’ and Product related skills associated with each PrO is to be assessed according to a suggested sample given below:

Performance Indicators

1. Interpretation of given problem
2. Draw sheet using different drafting instrument
3. Follow line work for neat and accurate drafting
4. Dimensioning the given drawing and writing text
5. Answers to sheet related questions
6. Submit the assigned sheet on time
7. Follow cleanliness and housekeeping in Drawing Hall
8. Attendance and punctuality

The above PrOs also comprise of the following social skills/attitudes which are Affective Domain Outcomes (ADOs) that are best developed through the laboratory/field based experiences:

1. Use drawing instruments safely.
2. Practice cleanliness and neatness.
3. Follow ethics and standards.

The ADOs are not specific to any one PrO, but are embedded in many PrOs. Hence, the acquisition of the ADOs takes place gradually in the student when s/he undertakes a series of practical experiences over a period of time. Moreover, the level of achievement of the ADOs according to Krathwohls Affective Domain Taxonomy should gradually increase as planned below:

• Valuing Levelin 1st year
• Organising Levelin 2nd year
• Characterising Levelin 3rd year.

Suggested Student Activities:

Other than the classroom and laboratory learning, following are the suggested student-related co-curricular activities which can be undertaken to accelerate the attainment of the various outcomes in this course: Students should conduct following activities in group and prepare reports of about 5 pages for each activity, also collect/record physical evidences for their (students) portfolio which will be useful for their placement interviews:

1. Students should collect Production drawings from nearby workshops/industries and try to visualize the part from the given views.
2. Prepare paper models of development of lateral surfaces of solids
3. Visit any sheet metal workshop and prepare a report related to type of components, dimensions, material, area of application, raw material required, name of operations performed.
4. Student should maintain a separate A3 size sketch book which will be the part of term work and submit it along with drawing sheets. Following assignment should be drawn in the sketch book
   1. Minimum 5 problems each on Unit No 1 and II.
   2. Minimum 2 problems each on Unit No III to VI.Note- Problems on sheet and in the sketch book should be different.
5. Prepare clay/ paper models of solids showing curves of intersection

Suggested Special Instructional Strategies:

These are sample strategies, which the teacher can use to accelerate the attainment of the various learning outcomes in this course:

1. Massive open online courses (MOOCs) may be used to teach various topics/sub topics.
2. Z in section No. 4 does not mean only the traditional lecture method, but different types of teaching methods and media that are to be employed to develop the outcomes.
3. About 15-20% of the topics/sub-topics which is relatively simpler or descriptive in nature is to be given to the students for self-directed learning and assess the development of the COs through classroom presentations (see implementation guideline for details).
4. With respect to item No. 10, teachers need to ensure to create opportunities and provisions for co-curricular activities.
5. Guide students in undertaking micro-projects
6. Demonstrate students thoroughly before they start doing the practice.
7. Encourage students to refer different websites to have deeper understanding of the subject.
8. Observe continuously and monitor the performance of students during practice.
9. Arrange visit to nearby industries and workshops for understanding various production drawings.
10. Show video, animation films, solid modeling software to explain intersection of solid, Assembly and details
11. Prepare wall charts for Dimensional and Geometrical Tolerances.
