5、udents are expected 1.to know the main features,distinctions,and relationships between theoretical,descriptive,correlational,and experimental research methods;2.to be able to analyze variables involved in certain research topics and identify the research method(s)applicable the topic;3.to generate r

7、 learning is based on three assessments:1.Writing assignment of a research proposal(40%)2.Two assignments of statistic data analyses via computer software application(20%)3.A final test on definitions of some key statistic terms and comprehension of empirical research documents(40%)What is Research?

16、een our experience both as active researchers that the first stages of exploring the ideas for research and developing the structure of the actual study are,without doubt,the most important.The components and procedures consists the research cycle.One might say that knowing how to look at research p

17、roblems and how to carry out research is related to the state of mind of the researcher(in relation to ones academic training,knowledge structure,field of study,perspectives and purpose)Interpretation of the following notions Research questions can be investigated from different perspectives by usin

18、g different procedures such as observation,questioning,experimentation,and elicitation.Can you give an example to verify this notion?that theories and hypothesis must be falsifiable.Interpretation of the following notions Scientific research seeks to describe,identify,and control relationships among

19、 phenomena in order to study them.E.g.Is there relation between phonological memory and foreign language learning?In what domain does the research question fall into?What method is more applicable?How to conduct the research?(definition,and measurement,control of other variables,data type and data a

20、nd procedure of data analysis)How to interpret the results and draw conclusions?Four Types of Knowledge Knowledge as belief:When we know something on the basis of belief,it may mean we want to believe something to be true but have never submitted it to an empirical test.Conclusions reached through“c

21、ommon sense”may be put into category.Such conclusions should be treated as possible hypotheses for research rather than as established knowledge about language.Four Types of KnowledgeKnowledge as authority:This type of knowledge comes from a source accepted by face value.Opinions about phenomena of

22、a scientist or researcher with high reputation are accepted as proven facts or as educated judgments.In language teaching,pre-dominating the methods are also good examples.Long(1981)claims that such activities promote optimal conditions for students to adjust their input to each others level of comp

23、rehension and thereby facilitate their second language acquisition.Four Types of Knowledge3.A priori knowledge This kind of knowledge starts with a set of axioms about some phenomenon and the developing our knowledge of it by using reasoning and logic working within the system defined by the axiom.4.Empirical knowledgeThrough observation,investigation and experiments.
