Lecture
Good morning, everyone. Today we will look at how to observe behaviour in research. In this lecture, I will briefly introduce two kinds of sampling, that is, time sampling and situation sampling.
Now first, time sampling. Time sampling means that researchers choose various time intervals for their observation. Intervals may be selected systematically or randomly. Suppose we want to observe students' classroom behaviour. Then in systematic time sampling, our observations might be made during five 20-minute periods, beginning every hour. The first observation period could begin at 9 am, the second at 10 am and so forth. However, in random sampling, these five 20-minute periods may be distributed randomly over the course of the day. That is to say, intervals between observation periods could vary—some longer others shorter. One point I'd like to make is systematic and random time sampling are not always used in isolation. They are often combined in studies. For example, while observation intervals are scheduled systematically, observations within an interval are made at random times. That means the researcher might decide to observe only during 15-second intervals that are randomly distributed within each 20-minute period.
Now let's come to situation sampling. Then, what is situation sampling? It involves studying behaviour in different locations and under different circumstances and conditions. By sampling as many different situations as possible researchers can reduce the chance that their observation results will be peculiar to a certain set of circumstances and conditions. Why? Because people or for that manner animals do not behave in exactly the same way across all situations. For example, children do not always behave the same way with one parent as they do with the other parent, and animals do not behave the same way in zoos as they do in the wild. So, by sampling different situations, a researcher can make more objective observations than he would in only a specific situation.
Q1. What does the introduction say about observing behaviour in research?
Q2. What's the difference between time sampling and random sampling？
Q3. What is situation sampling?
答案&解析：
1. 答案：C
解析：
根據(jù)文中Today we will look at how to observe behaviour in research. In this lecture, I will briefly introduce two kinds of sampling, that is, time sampling and situation sampling.可知， 開場簡短介紹當(dāng)中，講座發(fā)言人指出在研究觀察行為時，有兩種研究案例的方式，所以，答案為C。
2. 答案：A
解析：
根據(jù)文中第二段先是談到如何進(jìn)行time sampling到，后來轉(zhuǎn)折處?？?，however之后談到However, in random sampling, these five 20-minute periods may be distributed randomly over the course of the day. That is to say, intervals between observation periods could vary—some longer others shorter.可知，time sampling和random sampling不同的是兩者觀察時間間隔的不同，所以答案選A。
3. 答案：D
解析：
根據(jù)聽力原文中Now let's come to situation sampling. Then, what is situation sampling? It involves studying behaviour in different locations and under different circumstances and conditions. 可知，situation sampling主要是研究觀察總結(jié)人在不同環(huán)境、狀況下的行為，所以，答案為D。?
