Douglas Barnes (1976) prefaced his aptly titled book From Communication to Curriculum by pointing out that orthodox curriculum theory analyses curriculum process from the teacherâs objectives rather than learnersâ understandings. Engaging students in learning about their subject is a central concern for all teachers and teacher educators. The issue of task design in secondary education, how teachers view and use the pedagogic potential of different tasks to engage pupils with knowledge in different subjects, is central to this endeavour. Subject task design relates to the ways teachers translate the curriculum into the tasks and activities that they ask their pupils to do in order to facilitate developmental or higher-level understanding of curriculum content. This involves identifying the goal or purpose of the task, the resources available in a given setting, and the forms of instruction and intervention that allow pupils to process the information as they negotiate the task activities.
The background to this book on task design is that for the past 25 years the curriculum in the UK, and subsequently teaching, has been dominated by the introduction and implementation of government national strategies. In the secondary school environment this has often led to teaching through narrow and restrictive versions of âteaching objectivesâ and patterns of assessment that focus on product and external examinations rather than process and student development. This pattern of curriculum imposition is not unique to the UK of course and educators in many other settings and contexts will recognise the same pressures on teaching and learning. The danger is that pedagogic practices that promote studentsâ learning and knowledge transformation through active participation can be largely shelved (or hidden) in favour of a passive form of knowledge acquisition through transmission assessed by recall of knowledge gleaned from others or the mastery of technical skills.
One of the aims of this book is to help re-professionalise teachers and question approaches to curriculum imposition. The emphasis is on enhancing studentsâ learning, and prospective and experienced teachersâ practice, through a focus on curriculum design, classroom subject knowledge, subject task design, classroom organisation, assessment, student engagement and questions of agency in the learning process. We aim to help to develop an understanding of task design as a pedagogic tool that will provide insights for teacher training and teacher development in enhancing subject understanding and student engagement.
The focus on task design stems from many years of conversation: in the Department of Education at the University of Oxford (OUDE); in our innovative internship initial teaching education (ITE) programme (Benton 1990: McIntyre 1997); in sessions of our Masterâs in Learning and Teaching course; and in talks with both prospective and practicing teachers. The Oxford Internship scheme was set up by OUDE in 1987 in collaborative partnership with the Oxfordshire Local Education Authority and its local secondary schools. The commitment to school-based and research led teacher training was underpinned by âsustained critical dialogue between the different kinds of expertise which teachers and university lecturers could bring as equal partners to considerations of teaching expertiseâ (Hagger and McIntyre 2006: 15). The educational landscape may have changed, particularly in school governance and the role of local educational authorities, but the collaborative partnership between OUDE and Oxfordshire schools remains strong in both initial teacher education and in educational research.
Subject knowledge and concept acquisition
Mercer (2000) identifies three methods that good teachers use when they teach well:
- They use question-and-answer sequences not just to test knowledge, but also to guide the development of understanding.
- They teach not just âsubject knowledgeâ, but also procedures for solving problems and making sense of experience.
- They treat learning as a âsocial, communicative processâ.
(Mercer 2000: 160)
In other words good teaching is as much to do with the processes of pupilsâ learning as it is to do with the outcomes of that teaching. The act of learning for the secondary school student takes place within a constructed classroom zone (Newman, Griffin, and Cole 1989): instruction and learning within this zone involves both mediated activity and the participantsâ cultural contexts and past histories. Pedagogy, in this definition of learning, has to attend to both the cognitive and affective processes involved in learnersâ development. Teachers, to borrow Vygotskyâs metaphor, have to conduct the classroom environment whilst attending to the following questions regarding task design in the different motives and varied sub-practices of school subjects:
- What matters in my subject?
- How does task design relate to subject knowledge?
- What is meant by task demand?
- How do tasks/activities help students conceptualise?
Viv Ellis characterises subject knowledge âas a form of expertise that exists amongst people who engage in the same kind of practiceâ (Ellis 2007: 167). Ellis rightly warns against a potential pitfall involved in using metaphors of subject knowledge or pedagogical content knowledge:
The effect of such metaphors (intended or otherwise) is to distinguish between certain high-status kinds of knowledge that are fixed and universal (subjects or disciplines) and lower status forms of (albeit valued and valuable) âprofessionalâ knowledge that depends on âuse-valueâ and context.
(Ellis 2007: 167)
Pedagogy involves both knowledge about subject and knowledge about how to learn the subject. If the teacher or teacher educator as subject specialist is the all knowing master, then the apprentice could be viewed as being merely a spectator in their own learning. Learning is more complex and requires the learnersâ active involvement in the dialectical relationship of appropriation and internalisation. At the same time, it would be dangerous to ignore the importance of teachersâ knowledge of their subject and the ways in which to teach what Schwab (1978) described as the substantive (key concepts) and syntactic (ways of knowing and representing) knowledge required in a particular subject. Egan argues that the task of teaching is to help learners to engage with the symbolic representations of knowledge that remain hidden without the acquisition by learners of the cultural and social tools needed to translate them_
The educational task, then, involves the resuscitation of knowledge from its suspended animation in symbolic codes. The task is to convert, reanimate, transmute the symbolic codes into living human knowledge in studentsâ minds.
(Egan 2005: 95)
Designing classroom tasks to enable learning requires the teacher to attend to both the design of the learning environment and to conceptual design (see Derry 2013). Vygotsky (1998) and his colleague Shif extended Vygotskyâs (1988) theories of scientific and spontaneous concept development to the field of education. Vygotsky argued that scientific concepts have their origins in the structured academic activity of classroom instruction. Schools introduce scientific, logically defined concepts to students. Spontaneous concepts, on the other hand, emerge from the studentâs own reflections of everyday experience. The relationship between the two types of concept formation is dialectical: spontaneous concepts develop upwards towards greater abstractness just as scientific concepts develop downwards towards greater concreteness. Only when both concepts merge do students develop mature understanding.
Barnes (1976) argues that: âMany of the tasks set in schools do not make it easy for pupils to utilize their everyday knowledgeâ (Barnes 1976: 29). Barnes describes everyday knowledge as âaction knowledgeâ as opposed to âschool knowledgeâ rather than spontaneous or scientific knowledge but the interrelation between the two forms of knowledge is the same. In setting the activities for classroom tasks, teachers need to attend to the following questions:
- How are studentsâ everyday understandings used in the learning?
- What part does talk and language play and what is the role of the teacher in relation to this classroom talk?
- What areas of substantive and syntactic knowledge are learners engaged with?
- What kinds of support are built into different activities in the task sequence?
- What are the different support demands on the teacher, peers, or other adults?
- What are the different assessment demands?
- Do the activities allow opportunities for formative assessment so that support can be adjusted?
- Does the assessment of outcome allow assessment of the teaching objective?
Classroom task design
One of the first questions for teachers to ask when designing a classroom task is: what is the educational function of the task and how should its design maximise the learning potential? Alexander (2000) makes the following distinction between âtaskâ and âactivityâ.
The âtaskâ dimension of a learning assignment is concerned with cognitive demand, ways of knowing and kinds of learning while âactivityâ connotes the ways these are packaged for teaching purposes.
(Alexander 2000: 535)
Task design involves both elements of teachersâ understanding task demand and a focus on the design of the activities and classroom organisation in which the task demands are played out. Vygotskyâs followers Davydov (1990) and Elkonin (1999) used the phrase âlearning activityâ to describe the design of activities that address the development of studentsâ grasp and use of higher order theoretical concepts. The students in this sort of classroom are active agents in their own learning through social collaboration with their teacher and peers. It is in this same context that Vygotsky described the teacher as the conductor of the social environment: both integral to the activity but reliant on social interaction for the symphony to be played.
Doyle and Carter (1984), building on Doyleâs (1979) earlier conceptual framework of task analysis for integrating the academic and managerial aspects of classroom activity, argue that an academic (school) task has three elements: (1) a goal or product; (2) a set of resources or âgivensâ available in the situation; and (3) a set of operations that can be applied to the resources to reach the goal or generate the product. Doyle (1983: 162) wrote, âtask is more than just content. It also includes the situation in which content is embeddedâ. Doyle goes on to argue that task accomplishment has two consequences:
First, a person will acquire information â facts, concepts, principles, solutions â involved in the particular task that is accomplished. Second, a person will practice operations â memorising, classifying, inferring, analysing â used to obtain or produce the information demanded by the task.
(Doyle 1983: 162)
It is important to add that the situation in which these operations take place is a social one â the classroom environment. Shavelson and Stern (1981) argue that task design should consider the following:
- content â the subject matter to be taught
- materials â the things that learners can observe/manipulate
- activities â the things the learners and teacher will be doing in the lesson
- goals â the teacherâs general aim for the task (these are more general and vague than objectives)
- students â their abilities, needs and interests are important
- social community â the class as a whole and its sense of âgroupnessâ
(Shavelson and Stern 1981: 478)
The question remains: does the design of linked tasks clearly highlight what is to be learnt â both substantive and syntactic knowledge? In considering what is to be learnt, we need now to consider how that learning is supported by task design.
Designing contingent support for concept development
One of Vygotskyâs (1998) key theoretical points is that we learn through mediated activity. As Wertsch states of Vygotsky:
In his view a hallmark of human consciousness is that it is associated with the use of tools, especially âpsychological toolsâ or âsigns.â Instead of acting in a direct, unmediated way in the social and physical world, our contact with the world is indirect or mediated by signs.
(Wertsch 2007:178)
But our contact with the world is also mediated through our interaction with more âexpertâ others: more expert in their use of socially, culturally, and historically acquired and developed psychological tools. From the work of Wood, Bruner and Ross (1976), the concept of âscaffoldingâ developed as a metaphor to describe the wide range of strategies such as modelling, suggestion or structuring by which an adult or more e...
