Rocks in the head: Children and the language of geography

By Beverly Derewianka

This paper represents a very early experiment with implementing a genre approach to teaching and learning. The author’s son was one of the children in the class. Now in middle age, he still treasures his rock collection.

An action research project involving a class of seven-year-olds at a country school in Australia is described below. Their teacher, Fran Egan, had been introduced to Michael Halliday’s (2007) functional grammar and was keen to try applying her new insights about language in her classroom.

Although Fran was delighted with the children’s progress and attitudes to writing in their whole language/process writing classroom, many of the activities — retellings, expressive writing, guided reading and so on — had become divorced from the language happening in other learning areas. How could she get language out of the ‘language block’ and into the curriculum? How could she promote purposeful interaction between speaking, listening, reading and writing?

In her language programming, Fran widened her perspective from the individual activity to a whole thematic unit. The focus became language for learning, fostering an explicit consciousness of how language functions in the learning process.

In particular, Fran was interested Halliday’s notion of register. Register is a way of describing the relationship between the context and the language choices made in a particular situation. In the classroom, it is essentially the teacher who controls the context. The ways in which the teacher constructs the classroom context can help promote the sort of language that contributes to learning. The following pages describe the ways in which Fran designed certain contexts and how these contexts influenced the language of the classroom.

Exploring How Texts Work 2nd edition

According to Halliday, there are three main variables that determine the register of any particular context: the field, the mode and the tenor. We can represent this diagrammatically (see Figure 1).

Let’s look at how each of these influenced Fran’s programming.

Schema for Register and context

Figure 1: Register and context

The field

In basic terms, field refers to the ‘subject matter’. The content of any learning is ultimately embodied in language. To learn content is to learn language. The class had developed an avid interest in rocks and Fran decided to build on this, taking ‘why we study rocks’ as the theme of the unit. In a broad sense then, the field which Fran was planning to develop was geology, and in particular, rocks.

Fran acknowledged the children’s existing knowledge of the field of rocks, and was concerned with extending the field in both planned and unplanned directions. One of the functions of education is to help children explore and make sense of their world. Language is a major resource in this endeavour, as it is through language that we represent our world. Language enables us to express the relationships we perceive between phenomena in the environment. The children’s understanding of the field would be developed not only through the labelling or naming of various rocks, but through the identification of relationships within the field.

Fran therefore planned opportunities for the children to develop and use the language needed to observe, describe, define, compare, contrast, group, classify and generalise. The children’s knowledge of the field then would hopefully grow during the unit from their fairly random, everyday ‘commonsense’ knowledge about rocks to a more explicit, systematised, integrated knowledge.

This might sound like a rather onerous, sober undertaking for such young children, but Fran didn’t want to patronise them. She had high expectations and so did they. They were eager to ‘name their world’ in ever-increasing detail, to discover how it is organised and how it functions. And to do that they needed the appropriate language tools.

The mode

Learning can take place through the oral mode or the written mode (including images). Fran was interested in the different roles these modes play in the learning process.

We could look upon learning as a gradual ‘distancing’ process, from an involvement in the detail of the here-and-now to stepping back, reflecting, seeing the bigger picture, relating and consolidating, and putting things in perspective. In fact Halliday talks about a variety of modes, each playing a part in this distancing process. He plots these modes along a continuum, ranging from the sort of language that accompanies action to the sort of language employed in reflection.

At the ‘action’ end of the continuum, the language tends to be oral – the sort of exploratory, interactive language used when coming to grips with the content. Stepping back further, one might reconstruct the action by telling someone what happened or writing a recount of it. Further towards the ‘reflection’ end of the continuum, we can exploit the ‘frozen’ nature of the written mode as it invites us to play around with the thoughts captured on paper — to shape and refine them, to extend them, to make connections between them. At each step, choices are being made to select significant aspects of the experience/subject matter and order them coherently.

Schema for the mode continuum

Figure 2: The mode continuum

The tenor

Fran was aware, however, that the learning power of the various modes could only be fully utilised if the tenor in the classroom situation allowed for this to happen.

Tenor refers to the relationships between the participants and the roles in which the participants engage. The traditional classroom relationship between teacher and pupil is one in which the balance of power is somewhat unequal, with the teacher in control of the knowledge and the patterns of classroom interaction. The sort of language which flows from such a relationship is typically long slabs of teacher monologue, punctuated by routines of pseudo-questions, programmed answers and evaluative comment by the teacher.

More conducive to learning might be the sort of language which reflects a more even balance of power – where children feel comfortable to contribute information, to hypothesise, to admit ignorance, to ask questions, to make suggestions, to give opinions, to initiate topics, to take responsibility. Fran planned therefore that, at appropriate stages during the unit, the children would enter into a variety of relationships (teacher/ class, teacher/group, parent/child, child/child, child/group, child/class) each relationship enabling the child to interact and learn in a particular way.

Another closely related aspect of tenor that Fran took into account was the roles adopted by child and teacher. At times these were deliberately structured into the program according to the learning activity at the time. The teacher’s role would range from ‘knower’ to ‘co-learner’, while the children became ‘geologists’, ‘lapidarists’, ‘researchers’, ‘authors’, ‘apprentices’, ‘experts’ and so on. They were expected to actively assume the role, posing the sorts of questions and making the sorts of observations that such a role would demand. Adoption of these roles aims to empower the children, encouraging them to see themselves as responsible learners, apprentice members of the discipline, moving from a tentative grasp of the field towards a more informed, confident control.

The unit was designed not only to develop knowledge about rocks, but also to provide opportunities for the children to learn the sorts of roles necessary to become independent learners.

In summary, we can see learning language (and even learning itself) in terms of the mastery of a wide range of registers. Each of these registers is characterised by a particular combination of field, mode and tenor.

Figure 3 is an attempt at describing how a number of registers were developed over the three-week unit, starting at the ‘action’ end with physical engagement with rocks, employing a variety of modes as the children worked towards the ‘reflection’ end with the production of a written text (a jointly composed big book drawing together what they had learnt about rocks). It represents the learning process as a spiral with no definite beginning or end.

Putting it into practice

Fran designed a unit of instruction which consciously structured the learning context in terms of field, mode and tenor:

  • The field involved an ever-increasing knowledge of rocks, deliberately introducing an awareness of how the field is constructed through describing, comparing, contrasting, classifying, defining and so on.
  • The mode ranged from oral/active through to written/reflective as the unit progressed.
  • The tenor was reflected in the various roles and relationships engaged in by the teacher and children (and parents).

Fran was then curious to see whether this structuring of the context did in fact produce the sort of language which we would associate with learning.

In the following text we will trace through the stages of the unit as described in the spiral diagram, giving examples of the typical language produced at each stage.

a) Language accompanying action

To initiate the children’s formal study of rocks, an excursion into the surrounding countryside was organised, with a number of parents volunteering to drive the children. To a certain extent the types of rocks could be readily observed, with the students noting rocks in their natural state and rocks that had been used in the built environment. Otherwise the ‘content’ was determined by the children themselves, the open-ended nature of the activity allowing them to relate current knowledge to new information.

They first stopped at some old rock walls, previously just part of the familiar landscape but now seen through new eyes. While they speculated on the origin of the rocks, parents recounted tales from local history about how the walls were constructed by Irish immigrants. Then it was on to a cutting where the freeway made its way through a hillside. The children observed the layers of rock telling their stories of different geological eras. Nearby was a rock platform at the beach where they saw how the molten lava from nearby extinct volcanoes had solidified at the ocean’s edge. Then they went around to the harbour with its pebbly shore and smooth rounded rocks. Finally they made their way to the local quarry surrounded by stately walls of columnar basalt.

Along the way the children had noted several stone fences, a few houses and a school made of basalt, a sandstone church, the retaining walls of the harbour, the road surface, a couple of stone park benches and a number of other rock constructions, including of course their own sandstone school building.

Mode

The language, saved as a voice recording and captured on video, was primarily oral: very much ‘language accompanying activity’, or the language of observing and exploring in the here-and-now. The written mode also played a minor role in its function of recording, capturing fleeting thoughts for later retrieval. The field notes represented more than mere memory joggers, however. They were early attempts at identifying significant details from the wealth of experiences surrounding the children (see Figure 4).

Field notes

Figure 4: Field notes

Tenor

The relationship between the adults and children in this context demonstrated more of an ‘equal status’ nature, allowing the children the freedom to make discoveries along with their teacher and parents. The children themselves asked the questions, sharing information and giving instructions:
‘Come and see this!’
‘This one’s got holes.’
‘Look – sparks!’
‘Why have they got that column shape?’
‘It’s sort of crumbly.’
‘I know why it’s smooth.’

They believed themselves to be apprentice geologists and their language reflected this role.

Field

Their command of the field at this stage was a mixture of everyday terminology (moss rocks, gravel, orangey rocks, stones) and more specific terms (quartz, basalt, quarry, sandstone). In context, and in response to their questions, technical terms were introduced (igneous, latite, columnar basalt).

b) Recount

Mode

On their return to school, the class shared their experiences in the form of an oral recount. This was intended not only as a pooling of information, but as an initial ‘distancing’ from the action of the excursion — putting things in perspective, selecting significant aspects, ordering them in time.

This was followed immediately by further distancing: a written recount of the day’s outing in the form of a ‘joint construction’. With the teacher acting as scribe using the overhead projector, the class, drawing on their shared experience, jointly composed the text. Within this functional context, questions arose regarding sequence, tense, singular/plural, spelling and punctuation. Most of these were initiated and worked through by the children themselves, although Fran explicitly guided them towards a recognition of the typical features of the Recount genre:

  • an opening Orientation (putting the reader in the picture — who took part? when? where?) followed by a series of Events sequenced in time, finishing with a Reorientation
  • the use of connectives of time to link up the events (first, then, next, after that, later)
  • the use of place phrases tracking the route of the excursion (in the Jamberoo/Jerrara/Kiama areas, out of the school yard, at Jerrara, on the top of the fence, on the rocks, at the new bridge work, in the rock cutting, at the base, at the top, out of the hole, into Kiama)
  • individual, named, known participants (Year 2, Nicole, we, Jamberoo school, the Little Blowhole, Kiama, the Quarry)
  • action verbs in the past tense (we walked, we touched, they wiggled, we stopped, we travelled, we talked, we went, we finished).

Here is the ‘joint construction’ of their Recount:

Year 2 excursion to observe rocks

Year 2 became interested in studying rocks when one of the class members (Nicole) talked about a rock book she had read in Silent Sustained Reading. Year 2 and their class teacher, Miss Egan, decided to go on an excursion in the Jamberoo/Jerrara/Kiama area.

As we walked out of the schoolyard, we noticed the Jamberoo School Infants building is made out of sandstone. Our first stop was at Jerrara, where we could observe rock fences. We observed lots of things here. Firstly we saw how the rocks were not stuck together properly. Then we touched them — they wiggled. Barbed wire was placed on the top of the fence. There was dried coloured moss on the rocks. The colours were green, grey, white and light orangey brown.

Next we stopped at the new bridge work. The bridge was made out of cement. We saw mountains of rock that had been cut through. We saw little lines in the rock cutting. These were left by big building drills (jackhammers). There were fragments of rock left at the base. At the top there was a stack of rocks left by the workmen.

From the bridge we travelled down to the Little Blowhole. We noticed the rocks here were sharp and they had little holes in them. We talked about how the igneous rocks were formed long ago.

At the Blowhole there was a dark hole. It’s sort of a hole with cracks in it. When big waves come the water spurts out of the Hole.

Then we went into Kiama. We observed how a bridge’s foundations were being turned (changed) into cement. Then we went to the old Kiama School and saw it was made out of basalt.

Next we went to the Kiama Harbour shore. We noticed there was black sand from the volcanoes. The rocks here were mainly round and smooth. We saw cunji on the rocks.

From here we went to the Quarry. We saw column-shaped rocks. This was called latite. We also noticed that tar is shiny sticky stuff with sparkling minerals in it.

We finished up our excursion by climbing on a huge pile of rocks at the Quarry. It was interesting to observe and find rocks.


Tenor

Because they had all participated in the excursion, the children came to the writing task with something to say – the experience had been shared and each participant had something to contribute. The teacher took on the role of scribe, allowing the children to debate which points they felt were worthy of inclusion in an account of the outing. The teacher did not always play a passive role, however. The scribe can in fact exercise a great deal of power, and when necessary the teacher used this power to guide the children towards a more effective text — reminding them of their audience, pointing out inconsistencies in tense and pronoun reference, helping with the overall structure and so on.

Field

Generally, the field of a Recount is ‘what went on’ and tends to emphasise events. This Recount, however, is not simply an itinerary of the excursion. It also records the observations made by the children, and this is reflected in the high incidence of verbs (we noticed, we observed, we saw). We could represent the field of the Recount by drawing up strings of related phenomena from the text:

 Participants  Locations
Year 2
Nicole
Miss Egan
Jamberoo, Jerrara, Kiama, the schoolyard, Jerrara, the bridge, Little Blowhole, Kiama, Kiama Harbour, the Quarry 
 Rocks  Constructions
sandstone, cement, mountains of rock, stack of rocks,  igneous rocks, basalt, black sand from volcanoes, round rocks, smooth rocks, column-shaped rocks, latite, ‘tar’ — minerals, huge pile of rocks Jamberoo PS Infants School
rock fences
bridge’s foundations
Kiama PS Infants School 

Table 1: Field of recount

From the ‘rocks’ string we can see that at this stage the children’s knowledge about rocks is still expressed in everyday terms, with the occasional technical term creeping in (igneous, basalt, latite, minerals). As yet there is not much evidence of the children attempting to bring order to the field. This is understandable, as the purpose of a Recount is simply to tell what happened.

c) Classification activity

Mode

At this point they ‘shunted’ slightly backwards along the mode continuum towards the ‘action’ end. The children had brought back their rock samples and were now going to classify them. The small-group discussion, while fairly reflective and orderly, nevertheless allowed the children to question, interject, change their minds and react to feedback. This oral give-and-take led to rather unsophisticated written classifications in diagrammatic form (see Figure 5). Nevertheless, the ability to summarise in a precise, logical image is an important function of the written mode and was a significant step along the continuum.

Tenor

Roles were quite deliberately structured for this activity. The children were able to choose whether to be geologists, builders, lapidarists or rock collectors, according to their interest and knowledge. The children looked for the particular characteristics in the collection of rocks that would be of interest to their group:

  • The geologists examined the features of each sample, noted the location where it was found and hypothesised as to its origins, justifying their decisions.
  • The builders considered the different attributes of the rocks and classified them according to their possible uses.
  • The lapidarists grouped their rocks with an eye to aesthetic qualities.
  • The rock collectors classified their samples according to idiosyncratic criteria – shape, colour, size and so on.

In each group the children took their roles very seriously, genuinely trying to tackle the problem from the specialist point of view.

The peer/peer relationships of the small groups permitted the children to interact as equals, without the ‘expert’ adult inhibiting their attempts. For example:

 S1:  I think this comes from down in the earth because it’s got kind of bits of dirt in it.
 S2:  I don’t reckon this is glass. It doesn’t feel like it.
 S3:  I know, ’cause it’s been washed around.
 S4: Geologists can tell what ... they can tell what is what, and which is which, because they’ve got these special tools and stuff like that to open them up and see what they’re like ... this man and then he polishes it and stuff like that and then he sells it for a lot of money and ...
 S1: I think this one comes from the mountain because it’s got all like it was buried in the ground ... like ... ’cause it’s got all grassy patterns on it.
 S3: They’ve come from the sea because they’re all smooth and they’ve got ... um ... sort of like sea patterns and they’re real real clean and that one’s got all green on it and it’s really really smooth – like a giant button.
 S4: The blue rocks ... people might think they’re from the sea and the water made them blue, but Kirsty said they’re from the fishpond.

Field

The children made a valiant effort at the classifying activity (see Figure 6), but while they learnt a lot about the process of classifying (that is, going from the most general to increasingly specific classes, according to particular attributes), they were frustrated by the lack of a more detailed knowledge of rocks and their attributes. This awareness of their limited knowledge of the field is reflected in their later write-up as they moved towards the more ‘written’ end of the mode continuum.

d) Experimenting

Mode

Back towards the ‘action’ end of the continuum, the children carried out a variety of experiments on their rock samples in order to come to a more detailed understanding of the attributes of different types of rocks. The dominant mode was oral, although again the written mode played an ancillary role as the children dictated their observations to a group scribe. These notes were later shared with the whole class.

Tenor

In their role as ‘scientists’, they chipped and hammered and rubbed and scratched. Their language reflected a sense of responsibility for their own learning – an expectation that they would ask the sorts of questions and make the sorts of observations one would expect of a scientist:

‘The crystal cr ... smashed up in three goes.’
That’s why I’m experimenting with it.’
I’m gonna experiment with this one.’
You get a little bit on your finger and dab it onto the paper and it makes a red colour.

The small group resulted in a peer relationship which encouraged the children to participate on an equal footing. The following transcript shows children utilising the oral mode to negotiate meanings about rocks, empowered by their roles as respected, knowledgeable equals: ​

 S1 That will be shale. It could be shale.

Field

The field was one of doing (smashing, crushing, experimenting, squashing, watching) and of discovering attributes (very sharp edges, a bit too hard, too hard to smash up, crushed, orangey). The group was also keen to find out the names for the various rocks (What’s the name of the stone? ... Igneous ... firestone). They regularly compared their samples with those in a labelled rock collection (That’s slate. See how it’s the same? ... We know the name ... we know the stone’s name).

By this stage the children had enjoyed plenty of opportunities to explore the subject of rocks in the oral mode – using familiar terminology, but gradually acquiring more specific terms at the point of need. Every so often, they employed writing to preserve their observations. Fran then started to exploit the power of the written mode to begin ordering their experiences. All their understandings about rocks were to be brought together in the form of a big book. The children decided which aspects they were particularly interested in and formed themselves into groups to each produce a chapter on their chosen topic. They were now moving towards the reflective end of the mode continuum – going from the multitude of specific details to more generalised, orderly reflection.

e) Text talk

Mode

As a model for the students’ writing and to further deepen their understanding, Fran chose a short written Information Report on rocks. Using the overhead projector, she guided the children to engage with the text by identifying various features (for example, overall structure, paragraphing, technical terms, use of exemplification, as well as layout aspects such as headings, illustrations, captions, a glossary). See Figure 7 for a model text and an indication of the sorts of features identified by Fran and the children.

Labelled model text

In this activity, the teacher took on the role of ‘expert’, sharing her knowledge of text with the class. The children, however, were not passive recipients, but rather were invited to actively participate in deconstructing the text.

Field

The written text presented the field in an organised manner — filling in gaps in the children’s knowledge and drawing out relationships, in particular the class/ subclass taxonomy — as indicated in Figure 8.

Figure 8: Structure for presentation of field in written text

f) The big book

Mode

By now the class was well into the writing process. The oral mode was still important, as the groups pooled their knowledge and collaborated in researching and constructing their joint texts. However, it was the written mode that took precedence, as they sought information from books, jotted down their notes, organised their knowledge, drafted, redrafted, edited and finally published.

The children also worked on individual reports, summarising what each student now knew about rocks.

Tenor

The children assumed the roles now of researchers and authors and learnt the skills to make them competent. Most of the interaction was at the peer level as they shared their information, asked each other questions, made suggestions and came to decisions. Because of the constant and explicit modelling by the teacher (for example, text talks, impromptu joint constructions, public editing, shared book) the children were able to be independent and productive in their small groups.

Before publication, the class was fortunate to be visited by a real-life editor of children’s books, who took on the role of expert to answer their questions about what an editor does. They also had discussions with a group of Indonesian geologists visiting the area who were quite taken with the way that the children took seriously their role of ‘apprentices’ in the field.

Field

A perusal of the published big book reveals a well-developed knowledge about the field of rocks. The children appeared to be quite comfortable with the three major classes of rocks and happily took to the terms ‘igneous’, ‘sedimentary’, ‘metamorphic’, defining them in their own words (fire rock, a rock made up of lots of layers, two rocks pressured for a very long time). They also became aware of an extensive variety of subclasses (quartz, crystals, gems, slate, shale, marble, latite, sandstone, pumice, coal, columnar basalt, blue metal and so on).

They started to look at the composition of rocks and had an inkling about minerals. They also had a good knowledge of the characteristics of various rock-types and the uses of different rocks (see Figure 9).

Best of all, they did not see the acquisition of such knowledge as ‘difficult’ or ‘a bore’, as evidenced by the fact that many weeks after the theme had finished their enthusiasm had not diminished and they kept bringing samples to class and making collections at home.

A detailed analysis of the transcripts and written texts has since revealed that Fran’s planning had in fact produced the kind of registers which we would associate with learning, the children engaging purposefully with a variety of modes from action through to reflection; experiencing a number of different roles within a supportive environment; and gaining an increasing control over the field in question.
