processes respectively.
Course Overview

8. Course Objectives
A course objective specifies a behavior, skill, or action that a student
can demonstrate if they have achieved mastery of the objective.
As such, objectives need to be written in such a way that they are
measurable by some sort of assessment.
Course objectives form the foundation of the class.
Everything in the course should work together to ensure students
master the course objectives.

9. Course Objectives of Manufacturing Process
I The Importance of manufacturing sciences in the day-to-day life,
and study the basicmanufacturing processes and tools used.
II The knowledge in thermal, metallurgical aspects during casting
and welding for defectfree manufacturing components.

COURSE ARTICULATION MATRIX MAPPING:
Course Outcomes and Program Outcomes(CO-PO) Course Articulation Matrix
Mapping:
• Course Articulation Matrix shows the educational relationship between CO and PO.
Level of Learning achieved.
The matrix can be used for any course and to evaluate a course syllabus.
The Table 1 gives information about the action verbs used in the POs and the nature
of POs, stating whether the POs are technical or non-technical.

18. METHOD FOR ARTICULATION
1. Identify the key competencies of POs/PSOs to each CO and make a
corresponding mapping table with assigning √ mark at the corresponding
cell. One observation to be noted is that the first five POs are purely of
technical in nature, while the other Pos are non-technical.
2 Justify each CO - PO/PSO mapping with a justification statement and
recognize the number of vital features mentioned in the justification
statement that are matching with the given Key Attributes for Assessing
Program Outcomes. Use a combination of words found in the COs,
POs/PSOs and course syllabus for writing the justification.
3 Make a table with number of key competencies for CO – PO/PSO mapping
with reference to the maximum given Key Attributes for Assessing Program
Outcomes.

19. METHOD FOR ARTICULATION
4 Make a table with percentage of key competencies for CO – PO/PSO
mapping with reference to the maximum given Key Attributes for
Assessing Program Outcomes.
5 Finally, Course Articulation Matrix (CO - PO / PSO Mapping) is
prepared with Cos. and POs and COs and PSOs on the scale of 0 to 3,
0 being no correlation (marked with “ -”), 1 being the low/slight
correlation, 2 being medium/moderate correlation and 3 being
substantial/high correlation based on the following strategy
0 – 𝟎 ≤ 𝑪 ≤ 5% – No correlation. 1 – 5% < 𝑪 ≤ 40% – Low / Slight.
2 − 40 % < 𝑪 < 60% – Moderate 3 – 60% ≤ 𝑪 < 100% – Substantial /

graduates of a specific engineering program should be able to do.
PSOs written for the department of Mechanical Engineering is given below.
PSO 1: Formulate and evaluate engineering concepts of design, thermal
and production to provide solutions for technology aspects in digital

28. Mapping of each CO with Pos, PSOs
 Select action verbs for a CO from different Bloom’s levels based
on the importance of the particular CO for the given course.
 You need to justify for marking of the values in CO-PO
articulation matrix. Use a combination of words found in the
COs, POs and your course syllabus for writing the justification.
Restrict yourself to one or two lines.

36. ADVANTAGES OF ASSESSING SLOS...
1. Will help departments understand how to better facilitate student learning.
2. Will provide departments with feedback (e.g. Are your services providing
what they are supposed to beyond customer satisfaction? What skills are
students learning ?
3. Will enable students to articulate what they are learning and have learned
from attending the college inside and outside of the classroom.
4. Will help students be able to explain what they can do and what they
know.
5 Will enable students to better understand where they can go to learn
particular knowledge, skills, attitudes or values. Ultimately, will provide
students with a map of where various learning opportunities are available.
