1. Why cognitive explorative action games?
When people interact with each other, they leave traces of what they are doing. In communication, they produce utterances, for instance, which they use for certain things. Conversation Analysis, which was first introduced by Sacks, Schegloff & Jefferson (1974), is one branch of linguistics which investigates language on the level of the utterance. Sinclair & Coulthard (1992) adapted this methodology to Speech Act Theory for the analysis of classroom talk.
But dealing with teacher-learner interactions leads sooner or later to the question: what is going on in people’s heads? We need to understand the cognitive states that underlie what the interlocutors are doing on the visible and audible level of the interaction (cf. Schalley & Khlentzos, 2007). In a teacher-learner interaction, just like in any other type of interaction, the interlocutors use language for certain purposes. More precisely, they use language to carry out actions. These actions, on the other hand, are always connected to cognitive states and processes. This connection is often hidden in language use.
To give an example, let us take a look at conceptual metonymy. Here an instance from Niemeier (2004, p.111):
It is immediately understood that it is the driver of the Rolls-Royce who has left without paying. The Rolls-Royce stands here merely as a place holder. This intended interpretation is not expressed on the verbal level but is inferred by the interlocutor.
Levinson’s (2000, p. 16) particularized conversational implicature (PCI) works along similar lines:
In this short sequence, A infers the PCI against background information (including social conventions about how long guests usually attend a social event) which is not explicitly mentioned on the verbal level. Cognitive processes like these naturally occur in language use all the time. Especially in the teaching and learning context, where learning ultimately takes place in the learner’s head, essential parts of the interaction happen on the nonverbal level. We have to incorporate the cognitive level in the description of the interaction if we want to understand what is actually going on.
2. Knowledge building via re-representation
The cognitive states of the interlocutors are an essential part of any interaction. They are part of the picture of what is going on when people talk to each other. Teaching and learning interactions are no exception here. In contrast, these interactions revolve around a vast network of cognitive processes including reasoning, inferring, and understanding, that ultimately combine to what I call knowledge building, i.e., in other words, learning.
Furthermore, the increasing emphasis on 21st century skills (cf. Bellanca & Ronald, 2010) in educational science and practice including skills like creative, critical, and innovative thinking stresses the need to investigate the cognitive level of the teacher-learner interaction more carefully.
Chi & Ohlsson (2005) provide a psychological framework that helps us track learning in terms of what they call re-representation: the learner is anything but a blank slate waiting to be filled with new information (see also Pinker, 2002). In contrast, learning takes place when the learner re-represents her existing knowledge.
Chi & Ohlsson (2005, pp. 376ff.) categorize these changes of knowledge along the following lines:
Defining learning in this way, the question must be posed how these changes can be realized in the teacher-learner interaction. But before we look into this question in more detail, I would like to draw the reader’s attention to another important distinction: shallow vs. deep learning.
Understanding something on a deeper level includes much more than adding information to one’s knowledge base. Especially changes 5)-7) require the learner to form entirely new representations of a given problem or state of affairs. In doing so, the learner has to overwrite or re-represent prior knowledge, i.e. existing concepts are partly or fully deleted and replaced by new ones. This is what Chi and Ohlsson (2005, p. 387) call nonmonotonic change.
These re-representations often involve abstract thinking. Abstract thinking thereby goes beyond identifying common features of things and combining those to higher level categories. Abstract thinking in the sense proposed here already begins with abstract ideas (see also Ohlsson & Lehtinen, 1997). These are eventually combined to larger schemas.
It is this kind of change which is at the center of deep learning. In the following, I will lay out the basic design of a communicative model for teaching and learning that revolves around non-monotonic changes, particularly of the kind as stated in 5)-7). This model correlates deep learning to communicative actions in the teacher-learner interaction. I call it the explorative action game.
4. Teacher-learner interaction as explorative action game
Before we take a closer look at the model of the explorative action game, let me say a few words about dialogic teaching and learning. Over the last decades, evidence has accumulated which shows that dialogic interactions boost learning and help the learner to process information on a higher level of thinking (cf., e.g., Benware & Deci, 1984; Deci & Ryan, 1985; Kage & Namiki, 1990; Koestner, Ryan, Bernieri & Holt, 1984; Vansteenkiste, Ryan & Deci, 2008).
The communication model that I propose grounds in Weigand’s Theory of the Dialogic Action Game (2002, see also 2010). The action game is the smallest functional unit of communication. It consists of an initial communicative action by one speaker and the subsequent reaction by the dialog partner (see Fig. 1).
This pair of communicative action and reaction is embedded within the speakers’ “worlds” incorporating cognitive, perceptive and also emotive states of the interlocutors, as well as their cultural backgrounds, societal norms, personal habits, preferences, and background knowledge.
Adopting the concept of the action game to teacher-learner interactions, we arrive at pairs of communicative actions and reactions that have learning as the main goal. We will take a closer look at the detailed structure of the game in the next sections, especially with regards to the particular speech act types and their functions. For now it is important to see that the explorative action game is a game of discovery. In this type of game, learning is not merely about conveying or comparing information. In contrast, teacher and learner explore a topic in collaboration. The teacher introduces the topic through the explorative speech act, for example, in the form of what I have called elsewhere “deep explanation questions” (Feller, 2013), which hint to a specific cognitive strategy. The learner follows this strategy and actively contributes to the interaction by processing information along its lines. She eventually shares her thoughts in the communication through the so-called discovery speech act. I call this collaboration between the teacher and the learner in the explorative action game dialogic knowledge building (see also author, 2013 for more details on dialogic knowledge building).
4.1. The initial speech act: Exploring a topic
In this section we will look more closely into the function the initial speech act in the explorative action game (i.e. the communicative action), which I call explorative, has with reference to dialogic knowledge building (cf. Feller, 2013) and thus learning. What this means can be best illustrated against Searle’s (1969) formula F(p). F stands for the illocutionary function of the speech act, i.e. the purpose of the speech act or what the speech act is used for such as, for example, making a statement about the world, requesting information, or making a suggestion, among others. p is the propositional act, i.e. what the speech act is about. The propositional act itself consists of reference and predication. For example, a noun phrase like “my car” refers to a particular object in the world, which is represented as the concept [my car] in the speaker’s knowledge base. “is red” is used to predicate the color red to the concept [my car]. The car is ascribed with the property of being red.
Based on Searle’s formula, we can demarcate the following general structure for the explorative speech act:
Explorative in Fig. 2 denotes the illocutionary function of the speech act, which is in this case exploring a topic. More precisely, exploring is directed towards knowledge building via a specific type of knowledge re-representation as indicated by type of change in square brackets. These re-representations refer to Chi & Ohlsson’s (2005) types of changes discussed earlier which, in the explorative, are directed towards a specific topic presented in round brackets. The right side of Fig. 2 refers to how this speech act is instantiated in communication. As indicated by the arrow, the speech act correlates to a potentially open-ended set of communicative means. These means include not only lexical expressions but also cognitive and perceptive means. For example, the speaker might refer to things in her environment and elicit inferences with reference to given background knowledge that is not expressed verbally. In addition, as Weigand (2010) has pointed out, speakers can invent new communicative means ad hoc or overwrite existing conventions in a given situation. This is why it is elementary to work out the function side of the teacher-learner interaction. It is the function side which helps come to grips with the ever-changing side of communicative means.
4.2. The reactive speech act: Discovery as knowledge re-representation
Having arrived at the functional demarcation of the explorative speech act, we can now take a closer look at the reactive speech act: the discovery speech act. Following Searle’s formula once more, we represent this speech act as follows:
The illocutionary function of this speech act is discovery , meaning that the speaker changes her existing knowledge, thus arriving at new knowledge in terms of re-representations as discussed in section 2. As a reaction towards the explorative speech act, this speech act is about engaging in higher level thinking by abstracting and combining abstract ideas to complex schemas. These schemas are thereby directed by the particular type of change introduced in the explorative speech act. Again, just like for the explorative speech act, the set of correlating communicative means is potentially open-ended.
4.3. Selected types of explorative action games: non-monotonic change
Now that we have set the scene, let us take a look at selected action games of non-monotonic change. I will focus on Chi & Ohlsson’s types 5)-7). In the following, each of these types will be correlated with a corresponding explorative action game. The starting point for the construction of the action games are selected passages from school textbooks. These passages apply linguistic means that are used to instantiate a particular non-monotonic type of change.
At this point it is worth to note that the difference between text and speech is irrelevant for our purposes. What is important here is the communicative function of the text, not the medium of communication. The textbook passages could just as likely be part of the teacher’s speech. In all cases, they are in the role of the explorative speech act in the action game and are thus an appropriate data pool in this context.
4.3.1. The game of greater complexity
Following our definition in 5), let us look into the design of an explorative action game for greater complexity. For this purpose, we should answer the following questions:
Both a) and b) must be answered from within the explorative action game. In this context, we want to find out which communicative means map onto deep learning and how these means “manipulate” the learner’s cognitive processing of a given problem or topic.
4.3.1.1. Metaphor as complexity scaffold
In the coursebook
Furthermore, we read about multiplication:
Both definitions follow the basic construction A is B, where A is the tenor, i.e. the object to which attributes are ascribed, while B is the vehicle, i.e. the object from which attributes are borrowed. It is thereby important to note that A is B is not an identification statement; rather, we are dealing here with what we could call partial identification. It is only a specific set of attributes which are projected onto the tenor.
My claim here is that the metaphorical definitions help the learner to process the presented information on a higher level of thinking. The metaphors scaffold a re-representation of what is presented in terms of a complex theory of quantity. This is only possible because the learner operates on abstraction. More so, the learner’s processing of the metaphors requires that she uses abstract representations of the mentioned entities from the very beginning.
This game can be represented as follows:
What does this mean exactly? Well, it means that the learner conceptualizes multiplication by combining her schema of addition with her schema of repetition. Both these schemas are already abstract and eventually combined to the new, more complex schema of multiplication.
4.3.1.2. Irony as complexity scaffold
As I argued elsewhere (Feller, 2008), irony can be used to persuade people to take a specific course of action. This can also be applied to a “cognitive course of action”. In this sense, irony can be used to lead the learner to think in more complex schemas by combining some of her already existing schemas. Consider the following example:
Detecting and interpreting the irony in 3) is based on a complex re-representation of the question of God’s existence and the origin of the universe. The irony of 3) combines three distinct schemas:
We can represent the correlating type of explorative action game as follows:
By processing the irony of 3), the learner takes these three schemas and combines them to a schema of higher complexity: the ironic reading renders the verbally expressed schema i) as absurd, while ii) and iii) remain as plausible alternatives. The evaluation triggered by the ironic mode provides new combinatorial properties for the formation of the complex schema. Without it, the attempt to combine the single schemas would result in a conflict between i), on the one hand, and ii) and iii), on the other hand, which would abruptly end the reasoning process.
4.3.2. The game of higher level of abstraction
Following 6), it is again the two questions a) and b) which lie at the heart of designing the action game. In this case, the action game prompts a re-representation in terms of higher order principles that go beyond material features of concrete objects.
4.3.2.1. Simile as abstraction scaffold
In the coursebook
Taking a closer look at 4) and 5), we can see how analogy directs the learner to think in more abstract terms about the geometric shapes introduced. Both diamond and oval are compared to
Take a look at this representation of the game:
4.3.2.2. Metonymy as abstraction scaffold
Consider the following metonymies in
The metonymy in 6) is
In both 6) and 7), thinking is directed towards abstraction. In the
In this action game, metonymy, more precisely the
4.3.3. The game of shifted vantage point
As defined in 7), the game of shifted vantage point is about changing one’s perspective when processing a topic or problem. Changing one’s perspective is thereby not restricted to the perspective of a person; in other words, this does not necessarily mean considering a problem through somebody else’s eyes. Changing one’s perspective might also refer to one’s viewing a problem from a different angle, i.e. applying a different cognitive strategy when processing a problem or topic.
4.3.3.1. Quasi-synonyms as vantage point shifter
The mathematical operation of dividing is explained along two different concepts: sharing and grouping. The linguistic function which is put to use here is that of quasi-synonymy:
4.3.3.2. Narrative markers as vantage point shifter
Another way to help the learner re-represent a given problem is by clothing information in narrative terms. In the textbook
Word problems like this make the learner associate the provided information with concepts from a real-life context. In this particular case, fractions are applied to amounts of cooking ingredients. The learner can imagine measuring the “real” ingredients, breaking them up into smaller portions and combine these to the amounts stated in the recipe.
Shifting the vantage point from abstract numbers to real world objects scaffolds the learner’s processing of the underlying problem. The descriptive language of word problems, especially the real word references and the use of mental verbs like “suppose” work as cues that tell the learner to take on a different perspective.
Another example comes from the geography textbook
Shifting the vantage point throughout problem solving, the learner can merge the specific aspects of the different perspectives. She can crosslink features across the presented scales of environmental change and combine them to a complex schema that grasps potential interactions between the scales.
We have conceptualized teacher-learner interactions in terms of explorative action games. The novel contribution of this paper is thereby that the presented action games structure language for dialogic knowledge building, correlating speech act functions with the non-monotonic types of change “greater complexity”, “higher level of abstraction”, and “shifted vantage point”.
In the teacher-learner interaction, the teacher scaffolds the learner’s discovery of new knowledge via explorative speech acts. The learner responds with a discovery speech act, in which she communicates how she has changed her existing knowledge.
If the hearer in fact changes her existing concepts, is contingent on a variety of factors that lie beyond the immediate scope of the communicative means applied in the action game like the exact make-up of the learner’s existing knowledge base, her learning preferences and her abilities. For future research, it will be essential to pinpoint these other factors and understand how they exactly affect learning. Only then can learning as discovery be described comprehensively. New insights here will open up a number of possibilities to make teacher-learner interactions more fruitful and enjoyable by tailoring communicative strategies to the individual needs of the learner. I am confident that the model of explorative action games is a first starting point in this direction.
