What are they? Why should it be divided into “Introduction”, “Methods” and other sections?How many articles or research papers does the author cite? Why?,1. Critical ReadingHow to read research articles,What are the characteristics of the language of a research paper? Is it more formal and objective or informal and subjective? Why?Do you think it necessary to learn how to read and even write research papers? Why?,1. Critical ReadingHow to read research articles,Read the article “Research Reports for Technical Writing” on Page 24-26 and answer the questions below.How many basic elements are there in a research report or paper? What are they?Why is a good knowledge of previous studies of the topic necessary?Why is the procedures section important?,1. Critical ReadingHow to read research articles,Four. They are problem section, procedures section, result section and discussion section.,Because it will contribute to the credibility of the research.,It can allow the reader to duplicate the experiment if there is some doubt about your findings.,What are the contents of the discussion section?What are the major requirements of a research paper in terms of style?,1. Critical ReadingHow to read research articles,Accuracy, clarity, and completeness.,It may evaluate the research results fully, point out what questions remain unanswered and perhaps suggest directions for further research.,Group discussion:What is Critical thinking (CT) ?Why is CT important to university students as well as a citizen?Why is asking questions important?,1. Critical ReadingCritical thinking (asking questions),Critical thinking (CT) : a questioning or challenging approach to knowledge and perceived wisdom. It involves conceptualizing, applying, analyzing, synthesizing, and evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action.,1. Critical ReadingCritical thinking (asking questions),Tips to be a critical reader: -read between the lines and make inferences about the authors attitude which might be hidden in the passage;-ask probing questions to get to know and follow the authors train of thought in academic reading;-read the goals and corresponding questions you may ask.,1. Critical ReadingCritical thinking (asking questions),To identify the authors motives or the purpose of writing, you can ask questions such as: What is the theme / main argument of?Is the author trying to persuade readers or merely provide information?Might the author have a hidden purpose?What are the authors presumptions and bias?Does the author support one side of a controversy or appear impartial?Does the authors attitude lie implicit in the text?,1.

What would happen if?Can you propose an alternative?,1. Critical ReadingCritical thinking (asking questions),How to learn a long text?A reading circle is a reading activity where students, in a small group, read the same text but each student in that group has a different role to play in the whole groups overall understanding of the reading.Roles1) Word Watcher: looks for new vocabulary in the reading text to teach the group.2) Questioner: creates questions about the reading to ask the other members to check their understanding of the article.,1. Critical ReadingReading Circle Method,3) Illuminator: finds at least one supporting idea in each paragraph that you feel is important to discuss with the group.4) Connector: discusses with the group how the article might connect to any outside sources5) Illustrator: Creates a visual aid (either a mind-map of main ideas and supporting details or picture that best reflects the main ideas of the article).6) Secretary: records group discussion to share with the rest of the class.Now students are divided into several groups to do the following tasks.,1.

Whats the attitude of respondents to nuclear power?There is a big proportion of respondents who support to continue the production of nuclear power.,1. Critical ReadingUnderstanding the text,What is the major reason for the general lack of correct understanding of radiation?Mass media play a very important role in the misunderstanding of radiation. How can laypeoples understanding of radiation be improved?A school program should be designed to analyze everyday conceptions about radiation.,1. Critical ReadingUnderstanding the text,Group discussion:Do you think the three reasons he offered are valid? Do you think that the method is appropriate to the objective of the study? Can you suggest better alternatives?The survey was conducted among freshmen in Norway almost 20 years ago. Would the same conclusion be reached if you should conduct the same survey in your university, using the same 10 questions?Do you agree with the author that our misconception of radiation is often derived from the mass media? What do you think of the role of mass media which plays in our knowledge?,1. Critical ReadingUnderstanding the text,Task 3 Match academic words with their general words or definitions.

The answer betrays a lack of understanding that disintegration of a radioactive atom involves the creation of a new nucleus.The answer reveals that the respondents fail to understand that a new nucleus will be produced if a radioactive atom is broken.,1. Critical ReadingUnderstanding the text,2. In the constructivist approach to learning, the learners ideas and conceptions prior to instruction are seen as important prerequisites for learning.According to the view of constructivists, a persons ideas will survive school education and form an important basis for learning new things.3. The way out of this impasses may lie in taking the lay conceptions into account and increasing the integration between factual information and practical / political considerationsThe solution is to take lay ideas into consideration and combine factual knowledge with practical or political factors.,1. Critical ReadingUnderstanding the text,TASK 6 Summarize the main idea of the following paragraph closely related to the text in Critical Reading in theme, using one sentence only. Read the model carefully before the exercise.Different types of radioactive elements will make different health effects, according to characteristics of each type.,1. Critical ReadingUnderstanding the text,TASK 7 Write a paragraph of about 120 words to summarize the main idea of the text. The population should have sufficient understanding of radiation phenomena to secure individual safety as well as democratic decisions. Therefore it is necessary for the communicators of radiation information to be familiar with the laypeoples perceptions of these phenomena. A survey was conducted to examine non-experts conceptions of radiation phenomena. The survey revealed incomplete understanding of concepts such as radioactive decay, half-life and absorption of radiation and a lack of differentiation of between radiation and radioactive material. There are indications that the lay understanding of radiation phenomena is to a large extent formed by mass media and that “school knowledge” of these phenomena is not applied in situations in the real world. Thus, new teaching and information procedures are needed. These should take into account the learners perceptions and should integrate “school knowledge” with considerations belonging to the “real world”.,1.
