Reading Passage & Questions
QUANTITATIVE RESEARCH IN EDUCATION
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, conducted a well-known experiment in which he asked 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 of 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 of 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, they suggest 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 children’s logical thinking capabilities, but also the degree to which they could understand directions, their willingness to comply with requirements, how well the experimenters communicated those requirements, and how they motivated the children.
The same kinds of criticisms have been targeted at psychological and educational tests. For instance, Mehan argues that subjects might interpret 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 a moat, drawbridge, and parapets, along with three initial consonants: 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 arrived at the wrong substantive answer. The score sheet with the wrong answers does not reflect 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 questioning the validity of the measures upon which quantitative research findings are based. Some scholars, such as Donaldson, consider these to be technical issues that 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 might legitimately jeopardize the validity of all research of this type.
Meanwhile, there are also questions regarding the assumption in quantitative educational research that causes can be identified through physical and/or statistical manipulation of variables. Critics argue that this fails to consider the nature of human social life by assuming it is composed of static, mechanical causal relationships. In reality, social life includes complicated procedures of interpretation and negotiation which do not yield determinate results. From this perspective, it is not clear that we can understand the patterns and mechanisms behind human behavior simply through causal relationships, which are the focus of quantitative research. It is implied that social life is much more contextually variable and complex.
Such criticisms of quantitative educational research have inspired more researchers to adopt qualitative methodologies over the last three or four decades. Qualitative research focuses intensively on exploring the nature of certain phenomena in education instead of setting out to test hypotheses about them. It also tends to deal with ‘unstructured data’, which refers to data that has not been coded during the collection process according to a closed set of analytical categories.
The primary forms of data analysis include verbal descriptions and explanations, involving explicit interpretations of both the meanings and functions of human behavior. At most, quantification and statistical analysis play only a subordinate role. 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 toward 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.

Detailed Passage Analysis
Many educational researchers previously operated under the assumption that children progress through distinct developmental stages and cannot perform advanced cognitive operations until they reach the corresponding developmental phase. For example, Piaget’s famous experiment required children to compare liquid volumes in containers of different shapes. Even after seeing that the amount of liquid remained constant when poured, many children believed one container held more than the other. Piaget concluded that the children lacked the logical capacity for this task because they had not yet reached the necessary cognitive stage.
However, critics like Donaldson have challenged this interpretation. They suggest that children might simply be unwilling to “play along” with the experimenter or may misunderstand the questions. This implies that experiments are social interactions rather than pure measurements of logical thinking.
Mehan further argues that subjects may interpret questions differently than intended. In a language test where children were asked to circle the starting letter for “castle” next to a picture of a medieval fortress, many chose “D” instead of “C.” When asked to name the building, they said “Disneyland.” While their scorecards marked this as incorrect, it didn’t reflect a lack of reasoning; it simply showed they had a different perspective than the tester expected.
These points raise questions about the validity of quantitative research measurements. Donaldson views these as technical issues solvable through more rigorous experimentation, whereas Mehan believes they could undermine the validity of the entire research methodology.
Meanwhile, qualitative research has gained popularity by focusing on exploring the nature of phenomena rather than testing hypotheses. It handles “unstructured data”—information not yet coded into fixed categories. Primary analysis involves verbal descriptions and interpreting the meaning of human behavior. Studies by Lacey, Hargreaves, and Lambert in British schools during the 1960s pioneered this trend using participant observation methods.
