Using more native-like language acquisition processes in the foreign language classroom

Abstract This work presents the case for using native-like language and learning networks in the classroom-based teaching of foreign languages and suggests how this might be done for EFL lessons. Networks in both syntax and syntax learning are discussed. Language and learning networks are then identified using principles from Evolutionary Linguistics and Cognitive Linguistics. The work culminates in an examination of how the identified networks in language and language learning can be better employed by teachers in the classroom to improve retention and use. Three general lesson plan types are suggested, which correspond with the three language network types that have been identified, which go further to attach meaning to the structures learnt in class.


Introduction
All humans use language in the same way (Calude & Pagel, 2011;Fitch, 2011;Kemp & Regier, 2012): language is what humans do. Furthermore, humans did not invent language; rather, it arose over time (Hauser et al., 2014;Szathmáry & Smith, 1995). However, despite humans having used language for a long time, we still have much to understand about how we develop competency in the use of a language, how language is stored in the brain, how it is processed and produced in communication, and why language change over time benefits these. Moreover, we are still unable to facilitate development of proficiencies in the foreign language classroom that are close to those native children are able to develop in a very short time, and although a great deal of progress has been made in the last couple of decades or so to meet unknowns, much of the work in the aforementioned fields has not found its way into the foreign language classroom in the form of teaching practise. While it is clear that competency with a language comes about through use (Ellis, O'Donnell, & Römer, 2015;Tomasello, 2008), problems with content-based, task-based and other student-centred methodologies abound (Baecher, Farnsworth, & Ediger, 2014;Bruton, 2011;

PUBLIC INTEREST STATEMENT
The broader implications of this work are diverse and far reaching. On one hand, the work presented here explains why it has been difficult for past generations to use the foreign languages they learnt at school, and how we can change this for future generations. However, the work presented here also gives a good example of how teaching practices need to fit how the brain has evolved to learn in order to maximise the benefits conferred upon students in a formal learning environment.
The work begins by examining networks in words and structures and in language learning, goes on to identify those language networks that ought to be taught in EFL lessons and culminates with corresponding lesson plans.

Networks that contribute to language acquisition
Networks, like fishing nets laid out on a beach, can be two-dimensional, or if each point of connection, or node, connects to many other points of connection, can be in more dimensions. More complex systems can have links-or edges-of different strengths, exist only between specific nodes, have multiple levels or be active only at certain times (Davies, Kounios, & Power, 2015;Kivelä et al., 2014;Sayama, 2015). Networked systems pervade nature, including brain structure and function, and language.
It is important to note that these domain-general networks of activity and learning are also present in the brains of other animals (e.g. Bardella, Bifone, Gabrielli, Gozzi, & Squartini, 2016;Dehghani et al., 2016). Furthermore, learning actually changes brain networks (Bassett et al., 2011;Bola & Borchardt, 2016), meaning the brain can be seen as a network that is in constant flux. Indeed, if the physical structure of the brain is in flux, then so too must any stored information. Taking small combinations of stored information from cognitive networks and using them sequentially, whether in learning, processing or production, is called chunking, the small combinations being chunks. Chunking is a defining characteristic of how the brain learns and manages information and is thought to be instrumental in allowing integration of the short-term memory and long-term information retention and learning (Chekaf, Cowan, & Mathy, 2016;Fonollosa, Neftci, & Rabinovich, 2015;Lee, Seo, & Jung, 2012;Mathy, Fartoukh, Gauvrit, & Guida, 2016), and networks in language production and processing most probably rely on chunking. Having now looked at domain-general learning networks, the network-like structure of language will be examined.

Networks in language
Language structure is determined by brain function (Bickel, Witzlack-Makarevich, Choudhary, Schlesewsky, & Bornkessel-Schlesewsky, 2015;Garagnani & Pulvermüller, 2016;Skeide, Brauer, & Friederici, 2015;Zaccarella & Friederici, 2016), and is composed from combinatorial signalschunks-from networks of stored inventories (Carr, Smith, Cornish, & Kirby, 2016;Hoffmann & Trousdale, 2011;Martinčić-Ipšić, Margan, & Meštrović, 2016;Solé, Corominas-Murtra, Valverdie, & Steels, 2011). Furthermore, the signals from which language is composed are ambiguous in their meaning unless placed in context (Piantadosi, Tily, & Gibson, 2012;Wedel, 2012), and that context, and the meaning created, are derived from learning (van Dijk, 2006;Krishnan, Watkins, & Bishop, 2016;MacDonald, 2015;Tamariz, Ellison, Barr, & Fay, 2014;Ullman, 2016). For native speakers learning in their natural environment, learning depends on the frequency of exposure to a certain linguistic structure, or form, and its situational concomitant meaning. This meaning is initially generalised and ever more refined and segmented as the frequency of contextually experiencing the form-meaning pairing increases (Frost & Monaghan, 2016;Silvey, Kirby, & Smith, 2015). Therefore, bringing meaning to ambiguity through context results in a finite set of signals becoming a rich and flexible system of language that is able to convey infinite meaning. Nodes of ambiguous words in the environment are linked to nodes of ambiguous cognitive concepts and given meaning after being linked to other nodes by edges of context. Moreover, the process of composing signals from these networked components manifests the syntactic structures found in language.
For example, in English, embedded structures (Christiansen & MacDonald, 2009;Miyagawa, Berwick, & Okanoya, 2013), dependency of time, gender and number/countability-or parsing (Beuls & Steels, 2013;de Vries, Magnus Petersson, Geukes, Zwitserlood, & Christiansen, 2012;van den Bos, Christiansen, & Misyak, 2012) and collocations and linguistic formulas (Brezina, McEnery, & Wattam, 2015;McCauley & Christiansen, 2014) are all examples of networks that are ambiguous nodes of words and meanings until linked together by edges of context to create word-meaning associations. In this work, a specific type of collocation or formula will be concentrated on, namely a root word that appears with other words on separate occasions that change the context and therefore the meaning, e.g. past participles being found with different auxiliary verbs. Specific examples are presented below in Table 1.
Finally, networks in communication signals are not unique to humans (Collier, Bickel, van Schaik, Manser, & Townsend, 2014, Rey, Perruchet & Fagot, 2012, and as described above with domaingeneral learning being networked, gaining the ability to use a language-language acquisition-is the interaction of language networks, and learning and memory networks, which will be examined below.

Networks in the acquisition of syntactic structures and their concomitant meanings
Memory and learning are networked phenomena with different areas of the brain being linked together and playing different roles. Working memory, colloquially called short-term memory, is very limited and can store correctly three to five "chunks" of information (Baddeley, 2012;Cowan, 2010), and it is necessary to minimise any dependency on working memory when learning to use languages (O'Grady, 2015). Long-term memory, which is associated with learning, is understood as being of the following two non-exclusive types: procedural memory-implicitly learning through practice, such as learning a sport, playing an instrument or using tools-and declarative memory-explicitly memorising things like dates and names for an exam (Andringa & Rebuschat, 2015;Ellis, 2015;Morgan-Short, Faretta-Stutenberg, Brill-Schuetz, Carpenter, & Wong, 2014;Ullman, 2016).
Notice that the second and third rows and the last row in Table 2 are very similar to the three rows in Table 1.
To enable foreign language teachers to use language networks effectively in the classroom, it is necessary to know which form-meaning parings to teach foreign language students and how they are created by native speakers.

Identifying which form-meaning pairings to teach in the foreign language classroom and how they are created by natives
Having defined the roles of networks in language structure and acquisition, it is now necessary to know which structures are the most important to teach in a foreign language classroom, and how those forms are given meaning by users through experience. In this case, the "most important networks" being those that facilitate any rudimentary-level of communication. In order to do this, two different branches of linguistics will be employed: Evolutionary Linguistics (EL) and Cognitive Linguistics (CL). Both will be explained in greater detail below, but a comparison is presented below in Table 4. Essentially, EL is a way of understanding words and structures and CL is a way of understanding how meaning is attached to words.
Learning the meaning of language through use is a common phenomenon observed in action by all parents and all persons who go to live in a country where a different language is spoken. However, while CL can explain how meaning is attached to language, it cannot tell us to why it becomes attached to the language units it does, which is where EL is needed. To identify and use networks in language in the foreign language classroom, we need to employ ideas from EL and CL, and a comparison of both is presented in Table 3.
Evolutionary Linguistics is a framework of theories that model some reasons as to why words and structures change in terms of becoming easier to learn and use after being inherited from parental generations in the process of iterative learning, or learning by copying (de Boer, 2015;Kirby, Griffiths, & Smith, 2014). As they have social impacts, the processes that drive language change in EL are referred to as cultural selection (Steels, 2011;Tamariz et al., 2014). The implications for words and structures are broad, and EL has been used to explain semantic change (Landsbergen, Lachlan, Ten Cate, & Verhagen, 2010), syntactic change (Kirby, Tamariz, Cornish, & Smith, 2015) and vocabulary evolution (Smith, 2004).

Demarcation of word boundaries
Where's the ball gone?(the speaker marks the beginning of ball with "the" and the end of ball with the previously known word gone) allocation of syntactic category "Where's the foogy gone?""What's a 'foogy'?" (the listener knows it is a noun) Embedding combinations of regularly heard forms "I'm going to the park.""What are you going to do in the park?""I'm going to the park to play football.""The man with the beard.""Who? Which man?""The man with the beard who was talking to me before" Dependency of time, gender and number/ countability-or parsing-eliminating ambiguity "The teacher speak funny English daddy.""I know pal. It's a travesty. How many English teachers are there?""One.""The teacher speaks funny English" Learning processes that are more explicit Building meaning by comparing and attaching it to structure "Have you eaten your breakfast yet?""Yes, I have.""What time did you eat it?""At 6,30am.""The girl's (has) gone, but the boys haven't yet" Building meaning by comparing and attaching it to words Breakfast (morning), lunch (afternoon), dinner (evening)time words and verb aspects, e.g.I've already done it.I did it five minutes ago. She's already gone, but they haven't yet Generalising and transposing concepts of meaning between different contexts Past participles being used in different situation (perfect, passive or adjective) to infer that something has happened before the time of speakingVerb and preposition combinations Cognitive Linguistics (CL) is a branch of linguistic research that uses principles that are general to cognition as a whole to model some ways the brain learns and uses language from the environment. First, that an innate linguistic faculty does not exist, i.e. all brain-based competencies used for the production and processing of language are not language-specific; second, that the meaning of language exists in the brain as concepts; and finally, that meaning comes through use (Croft & Cruse, 2004, Pleyer & Winters, 2015. Core ideas in CL are the Cognitive Commitment and the Generalisation Commitment. Essentially, the Cognitive Commitment states that any ideas about how the brain handles language should not be different to how the brain handles any other task; whereas the Generalisation Commitment states that any principle in CL should apply to all human languages (Evans, 2012). Meaning coming through use, is referred to as the "usage-based" approach Janda, 2015;Tyler & Ortega, 2016), and two subthemes from CL, Connectionism and Constructivism, approach the topic in different ways (Lain, 2016). Connectionism sees knowledge as being represented as patterns of numerical activity across simple processing units; where processing occurs across large sets of connections in networks, and; in which learning occurs through non-language specific, general mechanisms combined with experience (Joanisse & McClelland, 2015). Constructivism sees individuals creating meaning over time through experience and active participation, rather than "acquiring it", and that this knowledge occurs within the context that was learnt (Ertmer & Newby, 2013). Both these ideas rely on the network structures of concepts and situational use (Baronchelli, Ferrer-i-Cancho, Pastor-Satorras, Chater, & Christiansen, 2013).

Combining EL and CL
Language exits as words and structures that human brains can attach meaning to and use to communicate effectively. Networks of cognitive form-meaning parings allow efficient communicationstorage, retrieval, processing and production-in real time (Chater, McCauley, & Christiansen, 2016;Garagnani & Pulvermüller, 2016), making language usable and learnable.
Language is usable because the different network types present in language-reusing the same word in different combinations/chunks/transposing concepts (Arnon & Christiansen, 2014, dependencies (Dyson, 2009;Hoffmann & Trousdale, 2011;Kuperberg & Jaeger, 2015;O'Grady, 2015;Omaki & Lidz, 2015;Traugott, 2014) and embedded structures (Lai & Poletiek, 2011;Piantadosi et al., 2012;Trueswell & Gleitman, 2007)-have evolved to be dealt with by a brain that operates using different memory types that have finite capacities for storage and processing (Krishnan et al., 2016;Vagharchakian, Dehaene-Lambertz, Pallier, & Dehaene, 2012) and uses proceduralisation and prediction to speed up processing (Huettig, 2015;van Schijndel et al., 2013).  Have got to do (obligation) Third person "s", apostrophe "s" and plural "s" Usability or learnability advantage as a consequence of change Other forms, which are more easily recalled, are now more common Transposing the concept reduces the amount of information that it is necessary to store and/or process and makes learning easier Recursive-like structures reduce the amount of information that it is necessary to store and/or process and makes learning easier These concepts are part of bigger networks that are integral to how the language functions, e.g. English does not work without plural/countable and singular/uncountable nouns or determiners Example of an iterated learning situation A child who has given his toy to someone: "Who did you give it to?" NOT "To whom did you give it?" To a child when she's finished her breakfast: "Done?" To a child who is hanging on his dad's leg: "I've got to go. Let go please." "Where mummy?""Where's mummy? Your mum's already gone out" Language is learnable because the combined characteristics of language and cognition mean an individual is able to learn his or her native language by interacting with the environment (Lain, 2016;Tamariz et al., 2014;Winters, Kirby, & Smith, 2015), and that other users of the same language distributed in time, e.g. generations, space, e.g. continents, can still understand each other (Silvey et al., 2015, Wedel, 2012 despite their different learning experiences (Foraker et al., 2009;Kirby et al., 2015).

Identifying specific examples of networked structures
Identification of the most important networked words and structures that are learnt in a natural, native environment that need to be taught in the foreign language classroom can be effected by employing ideas from EL. If language is changing to be more usable and learnable, it is necessary to teach the language that is changing as a part of the networks in which it is changing. To facilitate this analysis, the level of change has been categorised as follows: lost, has found multiple uses, currently changing and has not changed despite expectations. These categories and examples, are then cross-referenced with their proposed drivers of evolutionary change and contextual situations in which a native might become familiar with them are presented in Table 4. The forth column in Table 4, which depicts structures that have not changed despite an expectation that they might is not trivial. Networks of overlapping usages, some of which are vital to the functional integrity of the language, might conserve certain domains of linguistic structure through a language's evolutionary history, as with specific areas of restricted genome change in biological evolution (Blair Hedges & Kumar, 2003;Siepel et al., 2005). Furthermore, the third row, which presents examples of iterative learning situations, helps users to build a meaning and attach it to a structure: a process that leads on to the next section, which seeks to identify how specific concepts of meaning are formed.
Additionally, identification of the most fundamental networked concepts of meaning that natives attach to certain words and structures that need to be taught in the foreign language classroom can be effected using ideas from CL. The words and structures presented in Table 4 are processed in situations providing context, and meaning is formed over repeated episodes of use. Examples of how these concepts are linked with the concomitant language in the natural environment, which might be replicated in the classroom, are presented in Table 5 along with the three previously identified network types: embedded structures, agreement and transposed concepts of meaning from Tables  1 and 2. Having now identified the most fundamental form-meaning pairings in English that ought to be taught in the EFL classroom, it is possible to construct lesson plans that replicate these learning processes in lessons.

Replicating how natives use cognitive and linguistic networks to create and proceduralise form-meaning pairings in the EFL classroom
Having identified how networks are involved in language and language learning, presented below in Table 6 are three lesson plan types, based on the three learning networks identified, namely embedding, dependencies and transposing concepts of meaning.
The same language and learning networks have been followed in Tables 1, 2 and 5. However, implicitly learning from repeated expose to certain structures and explicitly attaching concepts of meaning to words and structures appear only in Table 2. That is because these learning processes need to be a part of every lesson. Furthermore, although these lesson plans aim to facilitate implicit learning as much as possible, it has been shown that in the early stages of learning a foreign language, implicit learning alone is not effective (Andringa & Rebuschat, 2015;Boers, Lindstromberg & Eyckmans, 2014), and some explicit instruction and declarative-learning is beneficial ( Morgan-Short et al., 2014). These lessons should therefore contain a minimum of explicit instruction, but the lessons must be repeated continually to facilitate implicit learning. Additionally, each lesson must contain an element that demonstrates that student has linked a concept of meaning to the language being used. These methods could be used to teach most of the structures used in everyday English, as depicted in Table 7.

Conclusion
Lesson plans have been suggested that purport to facilitate learning in a more native-like way in classroom-based EFL lessons, and thereby aid retention, recall and communication skill. The proposed lesson plans use the results of linguistic, teaching and neuroscience research to provide a bridge across the gap between compulsory foreign language students and children learning their native language in order to improve foreign language teaching.
Core to the argument presented is the use of the same three networks used in learning and the use that are present in English, namely embedded structures, agreement of dependencies and transposing concepts or meaning. It has been shown that the brain stores, retrieves, processes and produces information as networks of ambiguous concepts that gain meaning through context, and the lesson plans presented here use the same networks as those found in the networks in words and structures, and learning.
The teaching approach suggested might be termed guided-implicit learning, and it aims to intensify and speed up natural implicit learning processes such that the benefit provided by the necessarily limited amount of classroom instruction time is maximised. Furthermore, three general lesson plan types have been defined, which are based on the networks shown to be present in English and accessible by networked, domain-general learning processes in human cognition. .

Future research
Despite the advances made in teaching a foreign language that are made by incorporating the network principles discussed above, further resolution is necessary of the syntactic structures and the roles of language and learning networks determining how native speakers learn and use them.

Lesson plan type Examples of syntactic forms that might be taught using this approach
Embedding This method could be used to endow students with skill in the use of embedded structures, such as "be going to + [verb]" future, and relative clauses. Lessons would begin with familiarising students with a zero level structure in the first few weeks, and slowly introducing the embedded portion. Pictures and pair work would be used to build meaning Agreement of dependencies and comparing dependencies Here parsing-drills could be used to first indicate to students that they need to listen for, for example, third-person, present-simple "s", and then to use pictures and pair work to demonstrate the difference between, for example, "the boys give presents to the girl" and "the boy gives presents to the girls" and to create meaningTo build meaning for, for example, the difference between simple past "I did it yesterday" and present perfect "I've already done it", first a concept of the difference between "yesterday" and "already" needs to be formed Transposing concepts of meaning to different contexts Meanings for words that have multiple meanings that are demarked by their context can be done by first creating a concept for the base-form, and then introducing the different situations in which the base form-meaning pair is modified Table 7. Examples of syntactic forms that might be taught using these different teaching approaches

Teaching approach Examples of syntactic forms that might be taught using this approach
Embedding Be going to, relative clauses; "if" conditionals; relative pronouns as question words and in relative clauses

Agreement of dependencies and comparing dependencies
How much and how many; plural "s"; third person "s"; apostrophe "s" for possession; verbs as either gerund or infinitive after the head verb; order of adjectives; longer comparatives being "more + adjective"; time words and verb moods Examples might include how native speakers implicitly know to use a gerund ("-ing" form) or an infinitive ("to" form) of a verb when it is used as the subject of another verb, for example, "I want to do" or "I suggest doing". Another might be implicitly knowing the required order of adjectives, for example, "the fat, tired, old, grey, EFL teacher" and not any other combination. Certainly, data driven learning (Boulton & Tyne, 2013;Callies & Paquot, 2015;Gablasova, Brezina, & McEnery, 2017;Granger, 2008)-using software to analyse collections of language use grouped by type, for example, nativespeaking children of different ages, which is available for example, in the CHILDES database in the Talkbank system-will be indispensable in identifying learning and using networks in any future work.
