    Many education researchers used to work on the assumption that children experience different phases of development, and that they cannot execute the most advanced level of cognitive operation until they have reached the most advanced forms of cognitive process. For example, one researcher Piaget had a well-known experiment in which he asked the children to compare the amount of liquid in containers with different shapes. Those containers had the same capacity, but even when the young children were demonstrated that the same amount of fluid could be poured between the containers, many of them still believed one was larger than the other. Piaget concluded that the children were incapable of performing the logical task in figuring out that the two containers were the same size even though they had different shapes, because their cognitive development had not reached the necessary phase. Critics on his work, such as Donaldson, have questioned this interpretation. They point out the possibility that the children were just unwilling to play the experimenter’s game, or that they did not quite understand the question asked by the experimenter. These criticisms surely do state the facts, but more importantly, it suggests that experiments are social situations where interpersonal interactions take place. The implication here is that Piaget’s investigation and his attempts to replicate it are not solely about measuring the children’s capabilities of logical thinking, but also the degree to which they could understand the directions for them, their willingness to comply with these requirements, how well the experimenters did in communicating the requirements and in motivating those children, etc.
    The same kinds of criticisms have been targeted to psychological and educational tests. For instance, Mehan argues that the subjects might interpret the test questions in a way different from that meant by the experimenter. In a language development test, researchers show children a picture of a medieval fortress, complete with moat, drawbridge, parapets and three initial consonants in it: D, C, and G. The children are required to circle the correct initial consonant for ’castle’. The answer is C, but many kids choose D. When asked what the name of the building was, the children responded ’Disneyland’. They adopted the reasoning line expected by the experimenter but got to the wrong substantive answer. The score sheet with the wrong answers does not include in it a child’s lack of reasoning capacity; it only records that the children gave a different answer rather than the one the tester expected.
    Here we are constantly getting questions about how valid the measures are where the findings of the quantitative research are usually based. Some scholars such as Donaldson consider these as technical issues, which can be resolved through more rigorous experimentation. In contrast, others like Mehan reckon that the problems are not merely with particular experiments or tests, but they might legitimately jeopardise the validity of all researches of this type.
    Meanwhile, there are also questions regarding the assumption in the logic of quantitative educational research that causes can be identified through physical and/or statistical manipulation of the variables. Critics argue that this does not take into consideration the nature of human social life by assuming it to be made up of static, mechanical causal relationships, while in reality, it includes complicated procedures of interpretation and negotiation, which do not come with determinate results. From this perspective, it is not clear that we can understand the pattern and mechanism behind people’s behaviours simply in terms of the casual relationships, which are the focuses of quantitative research. It is implied that social life is much more contextually variable and complex.
    Such criticisms of quantitative educational research have also inspired more and more educational researchers to adopt qualitative methodologies during the last three or four decades. These researchers have steered away from measuring and manipulating variables experimentally or statistically. There are many forms of qualitative research, which is loosely illustrated by terms like ’ethnography’, ’case study’, ’participant observation’, ’life history’, ’unstructured interviewing’, ’discourse analysis’ and so on. Generally speaking, though, it has characteristics as follows:
    Qualitative researches have an intensive focus on exploring the nature of certain phenomena in the field of education, instead of setting out to test hypotheses about them. It also inclines to deal with ’unstructured data’, which refers to the kind of data that have not been coded during the collection process regarding a closed set of analytical categories. As a result, when engaging in observation, qualitative researchers use audio or video devices to record what happens or write in detail open-ended field-notes, instead of coding behaviour concerning a pre-determined set of categories, which is what quantitative researchers typically would do when conducting ’systematic observation’. Similarly, in an interview, interviewers will ask open-ended questions instead of ones that require specific predefined answers of the kind typical, like in a postal questionnaire. Actually, qualitative interviews are often designed to resemble casual conversations.
    The primary forms of data analysis include verbal description and explanations and involve explicit interpretations of both the meanings and functions of human behaviours. At most, quantification and statistical analysis only play a subordinate role. The sociology of education and evaluation studies were the two areas of educational research where criticism of quantitative research and the development of qualitative methodologies initially emerged in the most intense way. A series of studies conducted by Lacey, Hargreaves and Lambert in a boys’ grammar school, a boys’ secondary modern school, and a girls’ grammar school in Britain in the 1960s marked the beginning of the trend towards qualitative research in the sociology of education. Researchers employed an ethnographic or participant observation approach, although they did also collect some quantitative data, for instance on friendship patterns among the students. These researchers observed lessons, interviewed both the teachers and the students, and made the most of school records. They studied the schools for a considerable amount of time and spent plenty of months gathering data and tracking changes over all these years.
    Look at the following statements or descriptions (Questions 28-32) and the list of people below.
    Match each statement or description with the correct person or people, A, B, C or D
    Write the correct letter, A, B, C or D, in boxes on your answer sheet.
    NB You may use any letter more than once.

    A. Piaget
    B. Mehan
    C. Donaldson
    D. Lacey, Hargreaves and Lambert [br] There is an indication of a scientific observation approach in research.
选项
答案 D
解析 有迹象表明研究中存在一个科学的观察方法。关键词a scientific observation approach。D项Lacey, Hargreaves and Lambert出现于原文最后1段。纵观全文，前半部分阐述了定量研究法和该方法的一些问题，最后两段阐述了定性研究法的特点和优点，而科学的观察方法很有可能出现在定性研究法的描述中。在最后1段中，Lacey, Hargreaves and Lambert人名的附近，文中提到：Researchers employed an ethnographic or participant observation approach，although they did also collect some quantitative data，for instance on friendship patterns among the students．These researchers observed lessons，interviewed both the teachers and the students，and made the most of school records．They studied the schools for a considerable amount of time and spent plenty of months gathering data and tracking changes over all these years．即研究者主要采取人种学或参与观察的方法，偶尔也收集了一些定量数据，例如在研究学生的友谊模式的实验中。研究者观察课程，采访老师和学生，并充分利用学校对学生的记录。他们花了相当长一段时间在学校进行研究调查，并花了数个月收集数据和追踪这些年数据的变化情况。本题题干的关键词observation approach重现。因此，本题的正确答案为D。
