Looking at the system, I was thinking of what is actually happening, relating numbers to features. In applying the dichotomy to problem-solving tasks, we find an exact parallel, with students focusing either on the meaning, or on the words, numbers and diagrams themselves. The deep and surface approaches to learning can therefore be seen as characterizing a fundamental aspect of how students learn, applicable in different types of learning task. In contrast, the surface approach derives from an intention merely to memorize or to reproduce: These are general notes. I tend to write down certain things I rely on myself remembering for the next year or two. In this study 19 out of the 31 students exhibited both types of approach (Laurillard, 1979b). First I had to decide on the criteria of how to approach it, then drew a flow diagram, and checked through each stage. You have to think about it and LEARNING FROM PROBLEM SOLVING 135 understand it first.

Putting in diagrams helps you think clearly and follow through step by step. I chose this problem because it was more applied, more realistic. You get an idea of the different types of problem that exist from reading.

Surface Approach This problem is not to be handed in, but it will be discussed in the lecture because the rest of the course depends on this kind of thing. You just need to know what you need to solve the problem. But the operational outcome of this combination of judgements and perceptions is an intention either to understand or to memorize, and thereby to use either a deep or surface approach. The dichotomy has implications, however, for the way the student engages with the subject matter, and this is of crucial importance in problem-solving.

I tried to set up in my mind how I was going to do it.

First you have to isolate what one knows, or what facts are known. I started by writing down equations, but you should start by thinking of what you need.

I looked up the formulae and made calculations from those.

The essential difference between a holistic and atomistic approach is that whereas the former preserves the underlying structure of the subject matter content, the latter effectively distorts it, because the students pay no attention to the structure and concentrate only on juggling the elements together until they fashion a solution. The whole point of problem-solving as a learning task is that it should engage the students actively in thinking about the subject matter, and in operating on the relations within it, so that personal meaning can be created. The evidence from these interviews demonstrates that the two alternative approaches to problem-solving do exist, and clearly one is desirable and the other less so, at least if students are to be effective problem-solvers outside the narrow educational context. But we need a full understanding of how deep and holist approaches lead to a higher level of learning outcome if we are to make use of this finding in designing problem-solving tasks. What does it mean for a student to understand a topic, and how do different approaches to learning relate to I V LEARNING FROM PROBLEM SOLVING 137 understanding?

The next section introduces a theoretical analysis of these questions from which we can derive a further way of describing how students learn from problem-solving. Such descriptions refer to the structural aspect of human cognition, identified by the Gestalt psychologists, but they are elaborated in relation to the particular context of higher education. Thus we find, for example, that structure can exist in both holistic and atomistic forms. One of the techniques adopted was to arrange the factual and descriptive information about a subject on a series of cards, each one labelled with a description of its content.

Putting the information together would enable students to work out underlying principles (for example, of biological classification). Students were required to work can you buy a research paper out those principles (i. The organization of the subject was essentially hierarchical, but students could work in any way they liked, for example, from general points to specific ones, or vice versa, or across the topics. For the other, they built up the framework step by step from the details to the more general principles. The two strategies achieved equivalent outcomes because that was required by the task. Thus there appeared to be two distinct strategies, ultimately equivalent in outcome, but very can you buy a research paper different in process. This methodology is fundamentally different from that used by Svensson and Marton. Pask, like the information processing theorists, takes the structure of the material as given, and investigates what students do with can you buy a research paper that informa- tion, or how they process it. However, in parallel with this experimental work, Pask also developed a theoretical framework, which allows us to interpret his findings and apply them to more familiar learning tasks.

Pask developed Conservation Theory as a way of describing the logical structure of what an individual (person or even machine) must be to be able to learn, and what the nature of the relation is between this 138 the experience of learning individual and the subject matter to be learned. The second basic principle is that the individual must come to know a subject domain, must operate on it (manipulate its elements according to some plan or procedure) and must obtain feedback on the result of these operations. An obvious parallel is global theory generating localized experiments in scientific method — the prototypical way of can you buy a research paper learning about a domain. The two theoretical frameworks we may call A and B, may be different from each other, but must be operationally equivalent. When both are used to generate an output through the manipulation of lines and points, they will both generate circles. That alternative must then be tested by generating corresponding operations on the subject matter domain and checking that they produce the same results as the previous framework. The vertical pathways in the diagram may also be used to construct frameworks, as in scientific method. The three levels in the diagram indicate different aspects of the subject matter. From this purely theoretical account, Pask derived two styles of learning, both of which are necessary for understanding, i. These are theoretical descriptions of learning, but they may nonethe- less be applicable to the reality of student learning. Ten of the students were interviewed about three of their assignments, each one a problem-solving task — in chemistry (reaction kinetics), crystallography (stereographic projection) and metallurgy (equilibrium diagrams). Each teachback lasted 5-10 minutes and was recorded and transcribed paper writing services for college students for later analysis. The analysis was done by inspection, looking for examples of statements that described either operation learning (statements of rules or procedures) or comprehension learning (descriptions of concepts or interpretation of operational constructions). The analysis was checked by two judges who achieved an average of 82 per cent agreement in assigning these categories.

These students are clearly using operations — procedures and rules — but they are not operating at the level of the theoretical framework of equilibrium diagrams.
