1.1. Motor Learning’s Theory. Brief Review
Findings in the field of motor learning processes suggests the importance of the body-motor experiences experienced by the child in structured contexts (family, school, sport initiation, etc.) and unstructured (after-school, equipped spaces, etc.) in which to be physically active [
3]. Recent theories of motor learning, in fact, exceed previous theoretical models and paradigms based on the standardized and well-defined sequence of phases that attribute to each age (or stage of learning) specific and predefined expected behaviors. For example, Fitts & Posner (1968) describes the process of motor learning as the transition from the cognitive stage (what to learn) to the autonomous one (when and why to perform a certain movement), passing through the associative stage (how to perform the movement you are learning) [
4], while, according to Meinel & Schnabel (1987) the motor learning process involves the succession of three phases, such as coarse coordination, fine coordination and variable availability, characterized by the progressive improvement not only in terms of acquisition of motor skills, but also automation of gestures and movements [
5]. Schmidt (1975), on the other hand, applies the concept of scheme (proper to psychology) to define the generalized motor program as a class of actions that have similar structural characteristics [
6]. Learning, therefore, is understood as the result of a general program that, through adaptation to new situations and the variability of the surrounding environment, offers different opportunities for movement. In addition, the main theoretical approaches that dealt with the definition and description of learning processes and motor control - behaviorist, cognitive and ecological-dynamic - differ mainly in the ways in which they consider the relationship between perception and action in the execution of the movement. The behaviorist approach considers, in fact, motor learning as the response to a given external stimulus and attributes, therefore, great importance to behavior (product) rather than to cognitive-mental activity (process) [
7,
8].
On the contrary, the cognitive model considers the individual as an active, vigilant, and motivated entity for learning, and defines movement as the result of general cognitive schemes designed to guide or generate motor acts aimed at a purpose [
9]. In this model, perception represents the starter of any movement, followed, in order, by decision and any voluntary motor action. The succession of perception - decision - action presupposes the continuous recall from the memory of previous motor experiences to recover, compare and choose the best and most appropriate option to the specific situation among the different possible solutions.
According to the ecological-dynamic approach, instead, perception is considered a process through which the individual, without using what is contained in memory systems, identifies, discovers and experiments in the environment and from the environment a whole series of information functional to the execution of a given movement; this approach is also defined ecological since it considers the complex interaction between individual-task-environment [
10]. The decision, therefore, comes from the interaction between the person, the movement, and the environment - without necessarily resorting to memory systems - and, therefore, takes on meaning only within the perception-action association. According to the theory of dynamic systems, in fact, learning is understood as the direct result of the interaction of the individual with the surrounding environment and, this aspect, finds its highest representation and expression in the connection between perception-action [
11].
From a practical and applicative point of view, considering the individual differences of the students (cultural, sociological, psychological factors, family context, previous motor experiences, etc.) a same situation can determine and hesitate in movement and motor actions different and diverse.
The conditions dictated by the learning environment, therefore, offer to the students’ different opportunities for action and the possibility of performing multiple variations of a given movement that are, from time to time, adapted to situations that may be similar and similar, but not completely equal.
The variability of the motor responses of children is conditioned by the situation (near-far, large, small field, heavy-light ball, number of players on the field, etc.) already present in the environment or, in educational-educational school, intentionally proposed by the teacher. Any action is adapted based on the analysis of environmental constraints (e.g., running downhill; jumping a ditch; climbing a wall) and, therefore, the learning of different forms and modes of movement is prompted by the variation of the stimuli coming (and intrinsic) by the environment itself.
The model of the Constraints-Led Approach (CLA) is based, in fact, on the modification of the constraints and variants of the movement - in relation to the motor task, the environment and the ability of the performer - to encourage self-regulation and the implementation of the most effective motor solutions, with important implications in the field of education and sports (for example related to the ability to solve problems or make decisions) [
12,
13]. In this regard, international literature has also highlighted how non-linear educational approaches characterize the spontaneous learning of motor skills by the child, in which the teacher is assigned the role of "guide" which intentionally orients students towards the discovery and resolution of some motor problems [
14,
15].
Such an approach is expressed in the research, by the child and the teacher, of dynamic and variable learning contexts, able to enhance the body-stimulus/ external-environment relationship in order to guide decision-making processes (what to do) and problem solving (how to do?) towards the definition of a certain movement, leaving the possibility for the child to experiment, try, make mistakes and try a series of tasks and activities that are not predefined, but open, adapted and customized to the individual abilities-abilities of the individual [
16,
17]
From this perspective, the learning process takes on a more global and inclusive connotation, closely linked to the opportunities and constraints that the environment offers, and resulting from the reciprocal interactions between motor activity (e.g., motor task), child and environment [
14].
1.2. Neuroscience, Teacher’s Reflective Behavior and Motor Learning in Physical Education
Recently the fields of intervention and the activities that make up the disciplinary structure of physical education in the school, have undergone major revisions and organizational updates and a significant expansion, assimilating - sometimes in a hasty way - the repertoire of contents and activities proposed to students with motor skills, object of learning. If this is accurate in terms of the relationship between disciplinary content and learning objectives, it is not always accurate in terms of the learning processes that are required and solicited by motor experiences.
In fact, the teaching of motor skills necessarily takes place through a wide repertoire of contents and organizational methods but develops and proceeds further, since it will have to tend to mobilize the different factors that structure the motor competence itself. This will be possible using different teaching styles [
1] that will allow to promote the didactic mediation and the learning process of the student. In a teaching process, lesson, learning unit, curriculum, modulation, variation, and interaction of teaching styles determines different ways of information processing and response by the student, allowing different and personalized learning methods and a non-linear pedagogical-didactic approach [
14]
Physical literacy is a learning process that allows children to acquire the widest and most articulate motor repertoire possible to promote healthy lifestyles and learn increasingly complex motor skills transferable in relationship life and sports [
18] (Whitehead, 2013). Postural patterns (flex, extend, adduce, abdicate, elevate, slender, push, etc.) and fundamental movements skills (walking, running, jumping, crawling, rolling, climbing, throwing, grasping, etc.) represents, in fact, matrices for every movement, that, with the application of executive variants proposed by teachers, allows the learning of motor skills oriented towards the introduction to sport and sport [
5]. This process is also influenced by extrinsic (such as environment-related learning opportunities) and intrinsic factors (e.g., individual maturation and growth rates) [
18].
Recent evidence in the field of educational neuroscience on the processes and modalities that involve the nervous system, as a learning organ, allow you to appreciate the continuous changes and adaptations that occur at the cortical level during the learning episodes [
19]. Moreover, the neuro-cortical plasticity, and the consequent creation and stabilization of maps and neuronal circuits, are the result not only of the learning object (thing), but also of the learning modalities (like) how the brain learns a certain content [
20]. These discoveries have opened the way to new didactic-methodological reflections, giving increasing importance to how to teach the brain (learning) [
21].
Moreover, from the perspective of the PE teachers, the Reflective Practitioner Model presupposes the improvement of their own knowledge through thoughts and reflections on planned and unplanned actions and the analysis of the advantages and disadvantages in action (when a certain event happens) and on action (after the event happened) to improve personal teaching methods [
22].
The educational neuroscience led to the development of Teaching Brain, a model that reflects the dynamism that characterizes the educational relationship and reflects the complexity of the teaching-learning process [
23]. This approach, in fact, is based on the study of neural markers that are activated differently depending on the strategies and methodologies used by the teacher and, consequently, the responses and actions provided by the students [
24].
In addition, Gola (2020) underlines the pedagogical value of educational neuroscience: it is not only the learning experiences experienced by the child, but also, and above all, the quality and way the child learns to influence brain plasticity and cognitive development [
25].
1.3. The Spectrum of Teaching Styles: An Overview
The model of Teaching Styles (Spectrum Teaching Styles) proposed by Mosston & Ashworth (2008), is a current and important methodological reference to address the complexity of motor competence and to study the interactions between the teacher and the group-class, the degree of responsibility and educational decisions. Not only that, the integration of quantitative (daily motor activity) and qualitative (such as contents, experiences, and modes of teacher-student relationship) in the motor field, therefore, is an essential and indispensable junction [
1].
The Spectrum was presented as a unifying framework, a denominator to delineate teaching styles and it included 11 teaching styles: Command style–A, Practice Style-B, Reciprocal Style-C, Self-Check Style-D, Inclusion Style-E, Guided Discovery-F, Convergent Discovery Style-G, Divergent Discovery Styles-H, Learner Designed Individual Program Style-I, Learner Initiated Program Style-J, and Self-Teaching Style-K. The fundamental reference point regarding the variation of decisions from teacher to student. According to this conceptual framework Mosston & Ashworth (2008), through the definition of teaching styles, present the transition from teaching in which the teacher expresses the highest degree of responsibility and decisions, in the choice of activities and executive and organizational methods (e.g. in athletics or gymnastics), to an approach in which, on the contrary, decisions and choices involve the student in the foreground (e.g. in bodily expression, activities in the natural environment; etc.) [
1].
Therefore, according to the lesser or greater students’ decision-making autonomy, teaching styles are classified into reproduction styles (ranged from styles A to E) and production styles (ranged from F to K).
All areas of physical education have content that can be taught through reproduction styles and production styles [
1,
26,
27].
Teaching Styles understand and outline the contexts in which students can reproduce (by imitating or repeating) and produce (by discovering, reworking and creating) motor skills and knowledge. In the teaching styles of reproduction, the teacher is at the center of the teaching setting, defines the tasks and their executive parameters while in the production ones the student plays an active role, generating modes of response to open motor proposals, original and creative.
The model of Meaningful Learning proposed by Ausubel [
9] led teachers to enhance two processes:
In the first mode (which coincides with the presentation of the motor task), the learning process proceeds from the reception to the discovery (and vice versa); in the second, concerning the modalities of acquiring knowledge or skills into the individual cognitive-motor repertoire, children’s learning proceeds from the mechanical to the significant one (and vice versa).
In the first mode (reception) the teacher presents the task through reproduction styles, promoting first the mechanical acquisition of motor skills and then, through the enrichment of the relationship between previous cognitive- motor experience, more significant learning. In this case the didactic decision-making is attributed only to the teacher who proposes activities and motor tasks, mainly closed and predefined and that provide only one executive mode (e.g., predefined motor sequences in dance, gymnastics, defining number of repetitions and programmed series, intervals, etc.).
In the second mode, (a) the motor task does not provide a single executive mode, (b) the presentation is carried out through styles of production (guided discovery and problem solving), and (c) the students can autonomously discover the executive variants (spatial, temporal, quantitative and qualitative and their reciprocal relationships) of a specific motor skills in a mechanical way but gradually can connect them significantly to the previous motor skills and knowledge already learned, consolidating and reworking its bodily-motor vocabulary [
2,
27,
28]. In the concrete didactic action, it is particularly important to know how to vary and modulate the choice of each style that produces different effects on the student’s learning methods [
27,
28,
29].
Below a brief description of each teaching styles [
1].
Reproduction Styles
Command Style-A
Teacher takes all decisions (i.e., difficulty, duration, series, repetitions, use of tools, etc.) and students perform the task according to teacher’s instructions. Students are asked to reproduce a specific performance or response proposed by teacher.
Practice Style-B
Teacher prepares the organizational methods: individual tasks, in pairs, in groups, relay, paths, circuits, games. The teacher starts the learning process (or consolidation) of a motor skill by proposing the task in easy conditions, the number of executive variants is modulated according to the stage of the learning process (i.e., jump with the cord on equal feet joined, perform a flip forward, etc.). Performance difficulty, repetitions, duration, use of a tool are defined by the teacher. Students individually practice a memory/reproduction task while teachers provide private feedback.
Reciprocal Style-C
Students are asked to work together and in partnership, and teacher provide criteria of successfulness.
Two students work together on a motor task proposed by teacher. One student performs the task while the other gives feedback. The motor and observation times alternate. The students practice in pairs at the same time.
Self-Check Style-D
Teacher provides a sheet designed of motor skills (e.g., jumping with the cable, throwing the ball with one hand to a fixed target, etc.), according to predefined criteria. The students work independently and self-check their performance according to the criteria given by teacher.
Inclusion Style-E
Teacher identifies a motor task /activity, among the disciplinary areas, in which there are different levels of difficulty implying the proper use of executive variants (near-far; high-low; far-close; heavy-light; to one or two hands). The teacher proposes the different levels of difficulty for each student/sub-group and students may decide to perform the easiest or most difficult task by varying executive levels thus integrating the motor skills already learned.
Production Styles
Guided Discovery-F
Teacher defines subject matter, target concept and questions sequential design asked to students.
Students make decisions about certain subject within the topic designed by teacher and try to discover the predetermined motor answers.
Convergent Discovery Style-G
Teacher, as well as determine subject matter decision and target concepts to be discovered, designs specific questions to students allowing them to discover the correct way of performing a motor task. Students are asked to reason, question, and make logic-sequential connection to discover the correct motor answer.
Divergent Discovery Styles-H
Teacher makes decisions about the subject matter topic and specific questions to ask students. Students have to discover different and multiple solutions/motor answers to a question/situation posed by teachers.
Learner Designed Individual Program Style-I
The teacher chooses a disciplinary field, but it is the student who makes most of the decisions about his/her motor experience. The student decides what he wants to learn within the teacher’s programming, and then presents a personal motor sequence with the teacher’s supervision.
Learner Initiated Program Style-J
Students decide the disciplinary area, e.g., group games with small tools. The teacher provides the basic executive criteria, but the student and the group are/are responsible for the organization and conduct. The teacher, if necessary, can help the group through feedback.
Self-Teaching Style-K
Students decide completely the aim of learning, a new field/ theme researching insights and experiences to be performed and learned.
