INSTITUTIONAL STUDENT LEARNING OUTCOMES

 

[    ]

1. Effective oral communication: capacity to deliver prepared, purposeful presentations designed to increase knowledge, to foster understanding, or to promote change in the listeners’ attitudes, values, beliefs, or behaviors.

 

[    ]

2. Effective written communication: development and expression of ideas in writing through work in many genres and styles, utilizing different writing technologies, and mixing texts, data, and images through iterative experiences across the curriculum.

[    ]

3. Critical thinking: a habit of mind characterized by the comprehensive exploration of issues, ideas, artifacts, and events before accepting or formulating an opinion or conclusion.

[   ]  

4. Problem solving: capacity to design, evaluate, and implement a strategy to answer an open-ended question or achieve a desired goal.

 

[    ]

5. Intercultural knowledge and competence: a set of cognitive, affective, and behavioral skills and characteristics that support effective and appropriate interaction in a variety of cultural contexts.

 

[    ]

6. Information literacy: the ability to know when there is a need for information, to be able to identify, locate, evaluate, and effectively and responsibly use and share that information for the problem at hand.

[X]   

7. Foundations and skills for life-long learning: purposeful learning activity, undertaken on an ongoing basis with the aim of improving knowledge, skills, and competence.

 

[    ]

8. Quantitative Reasoning: ability to reason and solve quantitative problems from a wide array of authentic contexts and everyday life situations; comprehends and can create sophisticated arguments supported by quantitative evidence and can clearly communicate those arguments in a variety of formats.

PROGRAM STUDENT LEARNING OUTCOMES (PSLOs): The student will be able to:

1.  Demonstrate competency in safe management and operation of a vessel with propulsion power of not more than 250kW by:

  • Operating and maintaining the machineries
  • Calculating fuel consumption and storage requirements including solving basic engineering problems.
  • COURSE STUDENT LEARNING OUTCOMES (CSLOs) (General): The student will be able to:
  • Perform secondary connections of AC arc welding machine, make current adjustments, and switch the secondary power on and off safely.
  • Produce a uniform bead weld using shielded electrode at a designated point and keep the right arc length.
  • Perform string bead welding in flat position with shielded electrode.
  • Perform a weaving bead weld in flat position with shielded electrode.

COURSE STUDENT LEARNING OUTCOMES (CSLOs) (Specific): The student will be able to:
