More Components: Knowledge, Literature, Intellectual Projects


action; critical evaluation; instrumentalism; intellectual projects; knowledge; literature; policy; practice; reflexive action; research; theory; understanding; value stances

In the last two chapters, we first introduced the idea of a mental map for navigating the literature plus the tools for thinking that represent the key to this map. We then looked at the first map component: the two dimensions of variation amongst knowledge claims. Here we complete our introduction to the mental map by describing its other three components:

  • three kinds of knowledge that are generated by reflecting on, investigating and taking action in the social world;
  • four types of literature that inform understanding and practice;
  • five sorts of intellectual project that generate literature about the social world.


Figure 8.1 Tools for thinking and the creation of three kinds of knowledge about the social world

Three kinds of knowledge

The three kinds of knowledge that we distinguish are theoretical, research and practice. We describe each below and show how they relate to the set of tools for thinking summarized in Chapter 6. Figure 8.1 represents that relationship, showing that the tools for thinking play a central role. They are employed both to generate and to question the three kinds of knowledge.

What is theoretical knowledge?

The tools for thinking are most obviously reflected in theoretical knowledge – you cannot have a theory without a set of connected concepts. We define theoretical knowledge as deriving from the creation or use of theory, in the following way. On the basis of a theory about the social world, we make claims to knowledge about what the social world is like. The theory itself may or may not be our own and will have been developed on the basis of patterns discerned in that social world, whether through general observation (armchair theorizing), through specific investigations (empirically based theorizing) or a mixture of the two.

For example, in order to provide warranting for the claim that all children should be given the chance to learn a foreign language before the age of eight, an author might offer as evidence the theoretical knowledge that there is a ‘critical period’ for language acquisition. The theory upon which the author is drawing for this knowledge has been built up over the years by various theorists (beginning with Eric Lenneberg). The theorists have used both general observation about what happens when people of different ages learn a language and a range of empirical studies that have sought to establish what the critical age and determining factors are. Bundled up in the theory are potential claims about roles for biology, environment and motivation. The author would need to unpack these roles if the fundamental claim were to be developed into an empirical research study (to see how well it worked to offer foreign language tuition to eight-year-olds) or into practice or policy-based recommendations (about whether, and how, foreign language teaching should be introduced into schools).

So-called armchair theorizing can involve reflecting on personal experience in an area of practice. Normally one would also expect such theorizing to be supported by reflection on what the author has read in the literature, so that it draws on others’ theoretical, research or practice knowledge. Where the links with other kinds of knowledge are weak, armchair theorizing can lead to explanations or prescriptions for practice that are not backed by evidence. Anyone can dream up a theory. However, without the support of evidence, why should others accept it?

Empirically based theorizing entails the abstraction of generalities from specific evidence. Characteristically, existing theory is used to make predictions. The predictions are tested through experimentation, survey or observation. If the results fail to support the predictions and are considered robust enough, adjustments may be made to the theory (see Figure 2.1). Empirically based theoretical knowledge is thus knowledge that, potentially, can be critically evaluated by returning to the studies upon which it was based. However, theorizing necessarily entails abstraction. Some aspects of a claim to theoretical knowledge may be weak, not because of the original evidence but due to the degree of generalization that has been made from it.

Theoretical knowledge needs to be conceived of in the same terms as other kinds of knowledge. It is a form of evidence that is used by authors to justify their claims. Therefore, it can be critically questioned in the same way. How might you engage with a claim such as: ‘Lenneberg’s theory holds that there is a critical period for language acquisition, therefore children should receive foreign language teaching before the age of eight’? There are two basic approaches. One is to question the validity of the theory itself, by finding reasons why you believe that the ‘critical period’ hypothesis is illogical or ill-founded. The other is to challenge the claim to theoretical knowledge that has been derived from the theory, by offering counter-evidence from other domains: empirical studies and practice. Thus, one might ask: ‘what evidence is there that teaching foreign languages to eight-year-olds matches the predictions of the critical period hypothesis?’ and ‘what do foreign language teaching initiatives introduced in primary schools around the world tell us about what can be done?’

What is research knowledge?

Research in the social world entails the focused and systematic empirical investigation of an area of experience or practice to answer an explicit or implicit central question about what happens and why. Sometimes the domain is extended to normative questions about how to improve practice. Research knowledge consists of claims about what happens, supported by empirical evidence gathered through data collection and analysis in the course of an investigation. As described in the previous section, research is often based on predictions made by a theory. However, it can also be atheoretical, where it is not explicitly linked with any perspective, theory or model. In either event, because research cannot be conducted without using tools for thinking, it is inevitable that some concepts will be employed. They may be undefined and used unsystematically, but concepts are bound to inform choices about what evidence to gather and how to interpret findings.

The research approach may vary, from an investigation by professional researchers who do not attempt to intervene in the phenomenon they study, through an intervention study where researchers work in partnership with those they study to help them improve their practice, to practitioners’ action research where they investigate their own practice.

The research process proceeds through the application of particular methods or techniques for focusing the investigation, collecting data as the basis of evidence, analysing and reporting the results, and drawing conclusions about what they mean. These detailed methods tend to reflect a particular methodology, that is, the researchers’ philosophical assumptions about the nature of the social world and how it can be investigated (including whether social phenomena are or are not subject to universal laws).

The conclusions drawn, based on the results of an investigation, embody the researchers’ claims about what happens and why, and possibly about how to make improvements. These claims are typically made public by publishing an account of the research in the literature. The account may be more or less descriptive, explanatory or evaluative, depending on what explicit or implicit central question the researchers were attempting to answer.

What is practice knowledge?

You know a great deal about practice in your domain of the social world, but you may not be aware of just how much you know. We define ‘practice’ to mean ‘everyday activity’. Those engaging with practice knowledge interpret and evaluate their practice, guided knowingly or unknowingly by tools for thinking that are related – however loosely – to theoretical knowledge. Part of practice knowledge is largely unconscious: the know-how entailed in the skilful performance of practical tasks. Some know-how can be raised to consciousness by reflecting on practice, informed either by theories or by investigating and challenging habitual activity, as in some versions of action research. Practice knowledge that is made explicit embodies claims about what does or should happen in the practical domain concerned. This explicit practice knowledge is commonly summarized in the literature, as when experienced practitioners write an account of their practice, or where informed professionals (such as inspectors) report on their work in evaluating practice.

Practice knowledge claims in the literature are open to critical questioning for the same reasons as the other kinds of knowledge. Anyone can hold a view about good practice. However, you can always question what meaning is being given to the concepts used, whether the concepts are used coherently, how logically the concepts are linked together, and whether the claims are supported by evidence.


Any piece of literature may relate to one or more kinds of knowledge. Wallace’s article (Appendix 2) is clearly concerned with research knowledge generated by his empirical investigation as a professional researcher. Early on he states (pages 222–3): ‘I wish to explore empirical factors connected with the contexts of schools and consequent risks – especially for headteachers – that may inhere in their endeavour to share leadership’.

But his research focus is also informed by his combined cultural and political perspective, which channels his attention towards those empirical factors connected with uses of power as determined by different cultural allegiances. He both draws on theoretical knowledge and generates a model of his own to synthesize his findings. Further, his explicitly normative argument culminates in practical prescriptions, designed to influence the development of practice knowledge by school managers and trainers.

So this example of academic literature relates unequally to all three kinds of knowledge. At the top of the hierarchy is research knowledge. But theoretical knowledge is both drawn on and developed, and profitable directions are advocated for practitioners to develop more effective practice knowledge.

Four types of literature

It is theoretical, research and practice knowledge, written down and published, that constitutes the bulk of front-line literature. As you would expect, each kind of knowledge is commonly expressed through its associated type of literature. You will recall, however, that in Chapter 2 we distinguished four types of front-line literature, not three. The fourth type is policy literature. The different types of literature are characterized as follows:

  1. Theoretical – presents models and theories for interpreting and explaining patterns in practice.
  2. Research – describes systematic enquiries into policy and practice.
  3. Practice – written by informed professionals who evaluate others’ practice and by practitioners who evaluate their own practice.
  4. Policy – proposes changes in practice that are desired by policy-makers, thereby implying a negative evaluation of present practice.

Policy literature tends to emphasize practice knowledge, since policy-makers are essentially concerned with improving some practical domain. To a varying extent, policy literature may also draw on research knowledge and theoretical knowledge. A frequent point of discussion in professional groups is whether policy should be built upon, or at least informed by, these types of knowledge. In policy literature, authors will tend to base their vision for improvement on their evaluation of the present situation and this evaluation will be according to the values and assumptions underlying their political ideology. (They may or may not provide warranting from research knowledge for their evaluation of what is wrong with the present situation, and predictions about what will work better.)

When you first come across a text, it is worth identifying what type of literature it conforms most closely to, because each type tends to emphasize claims to particular kinds of knowledge. Each type of literature is prone to specific limitations affecting the validity of the knowledge claims it contains. By identifying the type of literature at the outset, you can alert yourself to what you should look for in the text to help you decide how convincing claims are, including any generalization about the extent of their applicability to different contexts.

Table 8.1 indicates some limitations of the four types of front-line literature. For each type, we have included an indicative list of features to look out for, which may affect the extent to which you find the claims convincing.

Table 8.1 Types of literature and indicative limitations of claims to knowledge expressed in them



These potential limitations underline how open to challenge and alternative interpretation our knowledge of the social world can be. Becoming a critical reader entails developing the habit of questioning whether such limitations have a bearing on claims made in the literature you encounter. Becoming a self-critical writer involves habitually checking whether your own claims might be subject to such limitations, then addressing those that you can resolve or work around, and acknowledging those that you cannot. (In the next chapter, we explain how you might react to these limitations when developing a Critical Analysis of a text.)


Just as the three kinds of knowledge relate to each other, so do the four types of literature. Our distinctions between types of literature are crude and many texts actually give unequal emphasis to more than one kind of knowledge. Combinations include:

  1. Theoretical literature illustrated by examples drawn from practice literature (e.g., an account of systems theory using the authors’ experience of higher education organizations to illustrate its application to practice).
  2. Research literature based on data drawn from practice literature (e.g., research to see if there is a correlation between different hospitals’ bed-occupation turnover and readmission of discharged patients).
  3. Research interpreted through theory (e.g., research using a political perspective as a theoretical framework).
  4. Research into practitioners’ informal theories of practice (e.g., research into the beliefs and values that guide senior managers’ leadership practice).
  5. Research reports commissioned by policy-makers to inform policy designed, in turn, to change practice (e.g., systematic reviews of research commissioned by a central government agency).
  6. Policy statements developed in consultation with representatives of practitioner groups (e.g., documents outlining national standards for patient care).

There are often sufficient clues in the title of a text alone for you to work out which type of literature you are dealing with (italicized in these fictional examples):

  • Theoretical literature – ‘An Ironic Perspective on Organizational Life’.
  • Research literature – ‘The Impact of Marketing on Consumer Decision-Making: A Large-Scale Survey of English Householders’.
  • Practice literature – ‘Effective Hospital Management: the Evidence from Inspection’.
  • Policy literature – ‘Generating Profitable Commercial Spin-offs from Innovation: the Way Forward’.

Failing that, you may get clues from an abstract, the blurb on the cover of a book, or the introduction and conclusion of the text. Theoretical literature will have a strong emphasis on one or more tools for thinking. Research literature will include a report or discussion of empirical evidence, whether gathered by professional researchers or by practitioners investigating their own work. Practice literature will focus on experience in some practical domain. Policy literature will tend to assert that existing practice needs improving or that a new practice should be implemented.


Look at the abstract for Wallace’s article (Appendix 2). Within it, certain key words indicate what type of literature it is: empirically backedfindingsresearchmodel.

Wallace is developing an argument about how leadership should be shared. His conclusion about sharing is backed by warranting that consists of findings from empirical research, which he reports. In the light of the research, he develops a model which uses patterns in the findings as a means of supporting his argument about the value of a contingent approach to sharing school leadership. This piece of research literature is therefore providing evidence to support a model, which itself legitimizes a conclusion. By this means, Wallace aims to convince the target readers of the paper that his conclusion is valid.

Elements of research and theoretical literature are being combined here. But this is research literature because the empirical investigation underpinning the model is the central feature of the author’s work. Whether the conclusion is convincing rests on the adequacy of the claims made possible by the investigation.

Five sorts of intellectual project for studying

An author’s intellectual project is the nature of the enquiry that she or he undertakes in order to generate the desired kind of knowledge and resultant type of literature. We identify five sorts of intellectual project, named for the outcome that they offer:

  • Knowledge-for-understanding – attempting to develop theoretical and research knowledge from a relatively impartial standpoint. The rationale is to understand (rather than change) practice and policy or underlying ideologies.
  • Knowledge-for-critical evaluation – attempting to develop theoretical and research knowledge from an explicitly negative standpoint towards existing practice and policy. The rationale is to criticize and expose the prevailing ideology, arguing why it should be rejected and sometimes advocating improvement according to an alternative ideology.
  • Knowledge-for-action – attempting to develop practice-relevant theoretical and research knowledge, taking a positive standpoint towards practice and policy. The rationale is to inform efforts to bring about improvement within the prevailing ideology.
  • Instrumentalism – attempting, through training and consultancy, to impart practice knowledge and associated skills, taking a positive standpoint towards practice and policy. The rationale is directly to improve practice within the prevailing ideology.
  • Reflexive action – practitioners attempting to develop and share their own practice knowledge, taking a constructively self-critical standpoint. The rationale is to improve their practice, either within the prevailing ideology or according to an alternative ideology.

As a critical reader, identifying the sort of intellectual project that authors have undertaken gives you an overview of what they are trying to do and how they are trying to convince their target audience. It provides clues about how they are likely to go about achieving their purpose and what the strengths and limitations of their approach may be. The type of literature that they have produced, the kind of knowledge claims they are making and the assumptions and values that lie behind these claims will all be linked to their intellectual project for studying. So once you are clear about the authors’ intellectual project, you will be in a strong position critically to assess the extent to which the claims are convincing.


Is the investigator relatively impartial, positive or negative about the issues under investigation?

  • Knowledge-for-understanding typically reflects a relatively impartial stance. The author is seeking to understand without wishing to try and improve what happens.
  • Knowledge-for-critical evaluation typically reflects a negative stance. The author is seeking to demonstrate what is wrong with what happens and may suggest a better way of doing things.
  • Knowledge-for-action, instrumentalism and reflexive action typically reflect a positive stance. The author seeks to justify and improve what happens, though there may be some measure of implicit negative evaluation of particular aspects of the current situation.

Postgraduate students are themselves engaged in an intellectual project as they develop work for assessment or publication. Their training commonly emphasizes knowledge-for-understanding, knowledge-for-critical evaluation and knowledge-for-action. In all three of these intellectual projects, critically reviewing the literature plays a central part in supporting or challenging claims to knowledge.

Whichever intellectual project you identify in a text, certain features should be discernible: the author’s rationale for undertaking the study, the typical mode of working, the value stance that the author takes, the questions that are typically asked, the way that theoretical knowledge is viewed, the type of literature that is characteristically produced and the typical target audience. In Table 8.2, the five intellectual projects head the columns. Each row indicates one feature and shows how it is manifested in that particular intellectual project. When reading literature, you can identify an author’s intellectual project by considering each feature in turn to check which project it best fits. In other words, the realization of these features can be used as an indicator:

  • Rationale for undertaking the study – indicates how authors’ explicit or implicit values about some aspect of the social world, their theorizing, research methodology and methods may affect their focus and the nature of the knowledge claims they make.
  • Typical mode of working – indicates which kinds of knowledge authors are attempting to develop and how they make use of different types of literature.
  • Value stance towards the aspect of the social world they are studying – indicates authors’ attitudes towards policy and practice and towards attempts to improve them.
  • Typical question or questions they ask about the social world – indicates which aspects authors are attending to or ignoring and the focus of the answers they are offering.
  • Assumptions about the place of theoretical knowledge in the study – indicates how authors employ any explicit definition of concepts and the extent to which they are drawing ideas from the social sciences or from practical experience.
  • Types of literature produced – indicates the kinds of knowledge authors are attempting to create, and where they publish.
  • Target audience – indicates the people whose understanding or practice authors wish to inform.

Bear in mind that these categories are simplistic and that, in reality, intellectual projects are not always pursued separately. You may expect to come across authors whose activity spans more than one intellectual project. For instance, an account of social science-based research, designed mainly to generate knowledge-for-understanding, may include in the conclusion some recommendations for improving policy and practice (reflecting a knowledge-for-action agenda). However, even in such cases, you will probably be able to identify a study as being primarily connected with a single intellectual project.

Table 8.2 Five intellectual projects for studying aspects of the social world




The title and abstract of Wallace’s article (Appendix 2) offer indications of the sort of intellectual project that he is undertaking. The following words suggest to us that Wallace is pursuing knowledge-for-action: justifiablenormativeshouldrisksimplications for training.

We judge that Wallace’s research and model-building are explicitly value-laden: developing a normative argument to justify a claim to knowledge about how leadership should be shared, on the basis of a study of what happens in British primary schools. His knowledge claim is directed towards informing senior school staff, trainers who design training programmes on school leadership and possibly policy-makers who commission them. Wallace points to the implications of his research, along with the model for improving training that he presents, as relevant to the improvement of school leadership practice. The centrality of his explicitly stated values about practice, his focus on implications for training and the absence of a critique of related policy and practice, all point towards a knowledge-for-action intellectual project.

Using Table 8.2 as a checklist, here is the emerging evidence for this conclusion, using just the title and abstract of Wallace’s paper:

  1. What is the rationale? To use the research findings to support an argument that may inform senior school staff, trainers and policy-makers about improving practice and related training.
  2. What is the mode of working? Evaluative research, where judgements are made about what happens and then used as a basis for model-building and, in turn, as a basis for identifying implications for training.
  3. What is the value stance? Positive towards sharing school leadership through teamwork.
  4. What is the question being addressed? Implicitly, something like ‘how effective are attempts to share school leadership through teamwork and how may they be improved?’
  5. What is the place of theoretical knowledge in the work? The author generates practical theory from his research findings.
  6. What type of literature is this? Primarily research literature because it hinges on data.
  7. What is the main target audience? Implicitly those who might be in a position to do something about addressing the training needs that are identified – senior school staff, trainers and policy-makers.

Four map components and a key to help you explore the literature

Approaching the reading of the published literature with a mental map will help you identify landmarks that indicate the purpose and nature of the material. Understanding what authors are trying to do, why and how, is a necessary prerequisite for making a fair critical assessment of their success in doing it. Selecting and commenting on arguments out of context can easily distort one’s view. A responsible critical reader aims to consider not only what is said but also the authors’ purposes, assumptions and intentions in saying it, along with an appreciation of whom the authors are primarily saying it to. Where you detect, by this means, that you are not a typical member of the authors’ target audience, it is still legitimate to indicate what information you would require in order to be satisfied (e.g., a stronger line of evidence to back up claims). You will be able to make this assertion in a manner appropriate to your understanding that the authors made choices on the basis of a different readership.

The mental map will be equally useful as a way of informing your writing where you develop your own argument evaluating what you have read. You may consciously deploy particular tools for thinking in constructing this argument, ensure that your claims are well-matched by the warranting you marshal in support of them, draw on and develop a form of knowledge or a mix of them, contribute to your chosen type of literature and be driven by your own clearly articulated intellectual project.

Let us, finally, recap on the relationship between the key to the mental map (Chapter 6) and the four map components (Chapter 7 and this chapter):

  • ONE set of tools for thinking (concepts, perspectives, metaphors, theories, models, assumptions and ideologies) is employed in creating authors’ claims to knowledge. These claims to knowledge are subject to …
  • TWO dimensions of variation – the degree of certainty authors have that a claim is true, and the degree of generalization that it is legitimate to make, beyond the context from which the claim was derived. Independently of the degrees of certainty and generalization, the claims made fall into one of …
  • THREE kinds of knowledge – theoretical knowledge, research knowledge and practical knowledge. Each kind of knowledge is related to the others. When these kinds of knowledge are written down, they are embodied in …
  • FOUR types of literature – theoretical, research and practice literature relate directly to each kind of knowledge. Policy literature reflects policy-makers’ evaluation of present practice and their vision for improvement according to their values. It may draw on practice and the other kinds of knowledge. Authors may produce these types of literature as an outcome of pursuing …
  • FIVE sorts of intellectual project for study – knowledge-for-understanding, knowledge-for-critical evaluation, knowledge-for-action, instrumentalism and reflexive action. The authors’ intellectual project governs the type of literature most suited to their purpose, the kinds of knowledge reflected and the degree of certainty and generalization with which knowledge claims are made, reflecting the way the tools for thinking have been used.

You are now ready to employ the mental map as an aid to becoming a more critical reader of the literature and a more convincing self-critical writer of texts for assessment by other critical readers. To demonstrate how this is done, we offer next a structured approach that can be used to conduct a Critical Analysis of a text.
