Preparation for Success Landis: Chapter 1 “Strangely, when new students come to the university, they are left primarily on their own to figure out how to be successful.” Success Strategies: • Determination • Effort • Approach

Landis Chapter 1: Keys to Success Key Idea: Each of you can be successful in earning your BSEE. It will take... • Determination • Effort • Approach

Determination: Don’t Give Up Use failure as a lesson, not as an excuse to give up. Set high goals. Keep them clearly in mind.

Goals • “Goals give you something to measure yourself against.” • “Goals give your life direction.” • Landis, Chapter 1. • Clarify your goals (this can be hard). • Short-term goals (“to do” list; Next calculus exam). • Long-term goals (education, career, family, ...). Important: What’s the big picture? What am I doing here?

Effort: Work Hard - Aptitude vs. Effort - For MOST students: Your grades will reflect your effort.

Approach: Work Smart • Prioritize • Form a study group • Learn to control your time • Learn to use available resources • - computer tools • - profs’ office hours • - student groups

In Class Assignment #1 In-class assignment for today (on 3x5 card): • Write your name (please print). • Write the full names of five class members, not including yourself. • Next to their name, write the name they want to be called. • Turn this card in before you leave today.

Approach: Work Smart • Prioritize • Form a study group • Learn to control your time – • I advocate that you use the rule of 4 • Landis advocates the 60-hour rule • Learn to use available resources • - computer tools • - profs’ office hours • - student groups

What is the Rule of 4? • Faculty members assume that you will spend 3 hours outside of class, for every hour in class every week. • Roughly speaking, a 3 semester credit hour course meets in class 3 hours a week. • Thus, the rule of 4 says that you should spend four times the number of credit hours you are taking on your coursework, every week.

What is the 60-Hour Rule? • Landis suggests that faculty members assume that you will spend 2 hours outside of class, for every hour in class every week. • Roughly speaking, a 3 semester credit hour course meets in class 3 hours a week. • The 60-hour rule suggests that your SCH x 3 plus your work hours per week should add up to less than 60.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: No, because I am taking 16 SCH, and I work 20 hours per week on my job. • Is this a good answer? • Dr. Dave’s Comment: This studentis not using the rule as a planning tool.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: No, because I have been keeping track of my time, and 1.5 hours of studying per hour of class results in my understanding the material. • Is this a good answer? • Dr. Dave’s Comment: This seems like a good answer to me.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: No, because my time is unlimited, so I don’t need time management tools. • Is this a good answer? • Dr. Dave’s Comment: I don’t think that anyone’s time is unlimited. Taking this approach can cause problems.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: No, because I study until I understand the material, so I don’t need time management tools. • Is this a good answer? • Dr. Dave’s Comment: This sounds like an admirable approach. It’s not. Taking this approach can cause problems.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: Yes, because Dr. Dave says that I should. • Is this a good answer? • Dr. Dave’s Comment: The Rule of 4 might be a bad use of time for you. You should figure out how much time you need.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: Yes, because I have not been keeping track of my time, and I need to start somewhere. • Is this a good answer? • Dr. Dave’s Comment: This seems like a good answer to me.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: No, because it is impossible to follow in today’s society. • Is this a good answer? • Dr. Dave’s Comment: I don’t think that society has anything to do with it. The demands of engineering are outside that. If you need to study that much, society doesn’t matter.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: No, because I like the Landis 60-hour rule better. • Is this a good answer? • Dr. Dave’s Comment: This seems like a good answer to me. This isalso a good planning approach.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: No, because I can’t tell how much time a course will need in advance. • Is this a good answer? • Dr. Dave’s Comment: I don’t think that this student is using it as a planning tool. One can’t know anything in advance. But you can still plan, using approximations.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: No, because it does not take into account the difficulty of courses. • Is this a good answer? • Dr. Dave’s Comment: This seems like a good answer to me. This student is taking an even more accurate approach.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: No, because my family will not let me keep a schedule, so I can’t use time management tools. • Is this a good answer? • Dr. Dave’s Comment: This is an issue of values. Indeed, if you have something else that is more important, you might not do well.

Student Replies • The students were asked the following question: Will you follow the Rule of 4 in the future? • Answer: No, because I am a working student, and it would take too long to graduate under this rule. • Is this a good answer? • Dr. Dave’s Comment: Maybe. But if you need to study a certain amount, and you don’t, it will take forever to graduate. That would be a really, really, long time.

Do Something! • Prioritize • Form a study group • Learn to control your time – • I advocate that you use the “Rule of 4” • Landis advocates the “60-hour Rule” • Do something! For many students, this is crucially important. • Learn to use available resources • - computer tools • - profs’ office hours • - student groups

Introduction to Engineering How can you tell an electrical engineer from a physicist? – Answer: by the goals they work towards. • An engineer's goal is to solve problems. • A scientist's goal is to learn. However, an engineer needs to learn to be able to solve problems, and a scientist needs to solve problems to learn, so the situation gets muddled. The key is to look at their goals.
