Outline 1 The Research Process Levels of Training in Research 2 3 Some Research Terms 4 Appendix A 5

1. The Research Process 1.1 What is research 1.2 Why are research methods used? 1.3 How are these research methods used? Stretches back to Aristotle A way of thinking and tackling a problem 胡適（師John Dewey）：大膽假設，小心求證(?)  should be 小心假設，大膽反證

1.1 What is research A systematic and unbiased way of solving a problem through generating verifiable data. John Dewey’s schema for cognition A puzzling situation Define the problem Formulation of hypothesis Collection, organization and analysis of data Formulation of possible conclusions Verification, rejection or modification *大膽假設，小心求證？ Stretches back to Aristotle A way of thinking and tackling a problem 胡適（師John Dewey）：大膽假設，小心求證(?)  should be 小心假設，大膽反證

1.2 Why Use Research Methods Scientific methods The most reliable way to move from limited, biased perceptions and opinions to fact or tentative truth Self-correcting nature Authority Personal experiences Common sense Intuition Scientific methods 啟蒙時代後才又重新發展 偏頗的論點，暫時性真理 自我矯正的過程，e.g., 逐漸趨向真理（向真理收斂）， 不斷的有反例出來  革命  進步 e.g., 黑天鵝 vs. 白天鵝

1.3 How to Use Research Methods Legitimate, ethical uses of research methods 抄襲，作假，杜撰：黃禹錫複製狗，誰砍櫻桃樹，睡覺聽教學錄音帶，早立志賺得多.. 科學 vs.人權，基因資料庫：醫生，雇主，保險，結婚. design a study: potentially harmful car components will appear to be safe? Politics of research, 花錢請人作假民調，genetically modified crops, Amazon & 出版社：cooperative advertising Taboo area, 複製人 學術倫理  balance 利害關係人  良心的譴責

2. Levels of Training in Research 2.1 Research literacy 2.2 Action research 2.3 Applied research 2.4 Basic research Stretches back to Aristotle A way of thinking and tackling a problem 胡適（師John Dewey）：大膽假設，小心求證(?)  should be 小心假設，大膽反證

2.1 Research literacy Ability to ask cogent questions Selection of research tools Analysis of data 基本功

A systematic process for gathering data 2.2 Action research Solving a problem which is of limited, local interest Research (Scholar) Evaluation (Manager) A systematic process for gathering data Answering specific questions or test certain hypotheses Gathering data on all parts of the setting or object under study e.g., 計劃案。相較於 Applied research更不嚴謹。 Evaluation：在通盤性的考量下提出建議。 Evaluation = Quantitative techniques (tests, questionnaires, scales) + Qualitative techniques (observation, anecdotal records, interviews) + Professional judgment source: Lang, G. & Heiss, G. D., A practical guide to research methods, 4th ed., 1991 Evaluation = Quantitative techniques + Qualitative techniques + Professional judgment Holistic, naturalistic To help real world decision makers

2.3 Applied research Solve an immediate problem or improve a product or a process Answering specific questions or test certain hypotheses. e.g., educational research: 相關，差異，因果 Basic (Pure) research：理論的來源。 Applied research：在實際世界中對理論加以驗證或應用。

2.4 Basic (Pure) research Increase understanding of fundamental principles. It is not intended to yield immediate commercial benefits. e.g., Alec Jeffreys 發現 DNA 如同指紋般每個人各異。 It is the basis for many commercial products and applied research. e.g., Alec Jeffreys 的發現應用在犯罪調查中。 IV. Basic research

3. Some research terms Operational definition (Constructs) Clearly define the key variables, concepts, and terms e.g., “intelligence”  Wechsler Adult Intelligence Scale Highly technical nature e.g., “ITS”, “VRP” (Vehicle routing problem) Common words with a very special meaning e.g., “Patent”, “Adult” and “Child” 

Ask yourself whether someone else reading your proposal clearly understands what you mean by that particular term. Research is one field where flowery rhetoric will do more harm than good. A researcher, unlike a politician, must be precise. * Socrates, Wittgenstein, William Shakespeare
