Participative Approach No Spoon Feeding General Goals Design of Control Systems and Development of Christian Character Curriculum Syllabus Instruction Variety of Methods Web Based Environment Tutoring Method No Student versus Instructor Responsibility and Interaction The only people who achieve much are those who want knowledge so badly that they seek it while the conditions are still unfavorable Favorable conditions never come CS Lewis Students are then strongly encouraged in the context of studying engineering fundamentals and applied disciplines to 1 Become immersed mind and heart and take ownership of the learning process 2 Strive for excellence in learning the fundamentals and applications of engineering design related disciplines 3 Consider engineering in a broader context and to appreciate the multi faceted nature coherency and unity of creation 4 Understand the real world reality in terms of businesses economics and politics in which projects are developed 5 Make the connection between faith and engineering practice and find ways in which engineering can be used as a redemptive tool 6 Translate into their designs normative sustainable characteristics and integrity or in other words the permanent moral values 7 Realize that Christian engineering though sometimes apparently indistinguished from the humanist technology needs to lead the way in considering the unity coherency and diversity of creation 8 Articulate and communicate their understanding through presentations and paper writing for professional and educational conferences 9 Grow and gain maturity in their emotions sentiments and spirituality 10 Demonstrate their passion and compassion as they seek to learn and serve God in the engineering arena All of these need to be achieved in a balanced way that is Christian engineers are to cultivate their relationship with God and seek to serve Him in all areas of life It often happens that two students can solve difficulties in their work for one another better than the master can When you took the problem to a master as we all remember he was very likely to explain what you understood already to add a great deal of information which you didn t want and say nothing at all about the thing that was puzzling you I have watched this from both sides of the net for when as a teacher myself I have tried to answer questions brought me by students I have sometimes after a minute seen that expression settle down on their faces which assured me that they were suffering exactly the same frustration which I had suffered from my own teachers The fellow student can help more than the master because he knows less The difficulty we want him to explain is one he has recently met The expert met it so long ago that he has forgotten He sees the whole subject by now in a different light that he cannot conceive what is really troubling the student he sees a dozen other difficulties which ought to be troubling him but aren t CS Lewis Quote from Derek Brewer about the way Lewis taught at Oxford through tutoring It conceived of learning as a way of life exemplified by the bachelor fellows who normally lived in the college They read books in their own rooms where they lived not in offices they had no secretaries Their reading thinking and writing were part of a unified life neither job nor recreation because they were both They did not strictly speaking teach In the morning and evenings of the term they were visited in their rooms by arrangement by their pupils who read the subject with them It was not exactly an egalitarian society but there was a sense of fundamental equality and unity divided into ranks and stages I had not doubt at the age of eighteen that for all the differences of temperament intelligence ability learning repute and age between me and this distinguished jolly man we were nevertheless of the same kind engaged in the same pursuit And the reason I felt this was no doubt because that was how Lewis treated me I was not a school boy to be taught and disciplined not a student but a man I only once detected a pupil offering me some one else Elton as his own work I told him I was not a detective nor even a schoolmaster nor a nurse and that I absolutely refused to take any precaution against this puerile trick that I d as soon think it my business to see that he washed behind his ears or wiped his bottom He went down of his own accord the next week and I never saw him again I think you ought to make a general announcement of that sort It is bad for them to think this is up to you Flay them alive if you happen to detect them but don t let them feel that you are a safeguard against the effects of their own idleness What staggers me is how any man can prefer the galley slave labor of transcription to the freeman s work of attempting an essay on his own Engineering is a human cultural activity that involves an interplay between theory experiment and imagination in which human beings form and transform nature for practical ends and purposes with the aid of tools and procedures Schedule Subject Chapter Introduction to The Nature of Control Systems Laplace Transforms Transfer functions of
