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, out of which, the practicals marked as are compulsory, so that the student reaches the Precision Level’ of Dave s 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 Weightage in %

Selection of suitable component, apparatus instrument 20%

Preparation of experimental set up 10%

Setting and operation 10%

Safety measures 10%

Observations and Recording 10%

Interpretation of result and Conclusion 20%

Answer to – ample questions 10%

Submission of report in time 10%

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. Follow safety practices.
2. Practice good housekeeping.
3. Demonstrate working as a leader/a team member
4. Maintain tools and equipment.
5. Follow ethical practices.

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 Krathwohfs ‘Affective Domain Taxonomy should gradually increase as planned below:

• Valuing Level in lSIyear.
• Organising Level in 2nd year
• Characterising Level in 3rd year
