The Impact of Personal Experience on the Professorial Practice in Physical Education : A Case Study from Tunisia

The observation of teaching practices of physical education (PE) at secondary school (Terrisse & Carnus, 2009) shows some differences at the level of “teaching thinking” (Tsangaridou, 2008), teaching conceptions and knowledge references. Indeed, Physical Education teacher can transmit knowledge by referring in multiple references. He teaches institutional knowledge (school curricula). However, he transmits also personal knowledge, personal conception and personal link to knowledge stemming from his personal experience and his sportive expertise. The research methodology is qualitative and descriptive. We refer to the clinical didactic methodology organized with three times constructed temporality. The aim of this case study (Terrisse, 2003) is to understand whether personal experience, revealing of teaching thinking, influences the nature and the form of teaching practice and the professional activity of a PE teacher during the teaching-learning process.

the process of teaching is complex and multidimensional, but that the behavior and the actions of the teachers, during the process learning-teaching, are widely influenced by what they think (Tsangaridou, 2008).
If the act of teaching is, on one hand, presented as an interactive, complex and professional activity, on the other hand this process must be examined as a result of a conscious or unconscious decision of the teacher.Indeed, knowledge, conceptions, faiths and values are conceived as explanatory elements of the behavior and actions of the teachers because they supposed to influence them (Calderhead, 1987).The primary objective of this current paper is to examine the impact of personal experience on practice teaching and didactic action of a PE teacher.
This comparative study proposes to examine the singularity of the teaching act.It relies on the study "case by case" or "one by one" (Terrisse, 1999).In this context, we are interested in the analysis of subject's singularity and complexity in the PE didactic framework.Our attention will be focused on the personal history of each teacher (Carnus et al., 2013) through the study of his "personal already these" (Carnus, 2003;Ben Jomaa, 2014).We are interested in the teaching of two Physical and Sporting Activities (PSA): sports specialty and another sports activity, by the same teacher.In the first time, we observe a cycle of gymnastics.Teacher C knows specifically this PSA.He practiced it since his childhood, as sports specialty.In the second time, we observe a cycle of basketball.Teacher C does not know enough this PSA because his doesn't practice it outside the school.However he must teach it because of institutional programming and school curricula.

Problematic and Research Questions
We postulate that the "teacher C" hasn't got the same link to knowledge, to body and to PSA.The theoretical and methodological tools allow us to describe and explain this comparison and join a particular epistemological position: the PE clinical didactic.The question of knowledge delivered in class is certainly dependent, on one hand on the institutional constraints already described by Chevallard since 1991, on the other hand it is certainly dependent on the personal constraints which structure the teaching subject and which can explain the causes of some didactic phenomena (Ben Jomaa et al., 2007;Ben Jomâa & Terrisse, 2011).Indeed, the teacher is a "didactic subject".He is autonomous and responsible.His personal history, his private approach and his professional epistemology are central elements in his decisions (Carnus in Terrisse et al., 2009).
The present research study sought to provide answers to the following questions: 1. Does personal experience influences the nature of knowledge transmitted and the practice of teaching?2. Is there a relationship between personal didactic approach (link to knowledge, references of knowledge, link to PSA) and professional practices?

Conceptuel Framework
In this research, we refer to the concept of link to knowledge.It's a fundamental concept/reference for the study of knowledge transmission in PE, even in the other disciplines.Indeed, this didactic concept implies the consideration of the way that a subject is affected by knowledge (De Leonardis, Laterrasse, & Hermet, 2002).Certainly, this notion takes us back to at least three references: didactic, sociological and psychoanalytical.But its aim is to analyze the transformations, which infer the apprenticeship in terms of corporeal transformations for pupils and teaching conceptions for teacher.Therefore, we mean by link to knowledge the creative process of a donor (subject) of sense (Beillerot, Blanchard-Laville, & Mosconi, 1996).
We also refer to the concept of break of the didactic contract (BDC) as an object of didactic study susceptible to explain certain dysfunctions and to think of the didactic phenomena in terms of regulation.The didactic contract is defined by Brousseau (1986) as a system of mutual, explicit and implicit obligations, which determines what every partner is responsible for the apprenticeship (for pupils) and the contingency management (for teacher).The specificity of the contract lies in its tendency to be negotiated as an anti-contract because it is subdued to the contingency of the didactic situation.This BDC consists in the transformations of knowledge object connected to the modifications-explicit or implicit of knowledge stakes (Reuter, Cohen-Azria, Dauney, Delcambre, & Lahanier-Reuter, 2007).This notion serves as an analysis tool of the teacher expertise through the way which the teacher transmits knowledge.These can be interpreted from the speeches (verbatim) and from the didactic gestures used by the teacher such as the ostension.This latter is defined as the monstration of knowledge, by differentiating it in direct, verbal and gestural according to the scale of Salin (2002), for giving pupils an image of corporeal gesture and to identify the distance that the teacher has from knowledge (Berdot, Blan-chard-Laville, & Camara Dos Santos, 1997).Thus, we use the distinction personal/official knowledge as an analysis indicator allowing to show the weight of the personal/official knowledge in the speech (and gestures) of the teacher during the management phases of the BDC.Indeed, we use indicators produced by our research (and spotted in the verbatim of the teacher before, during and after the teaching act) to identify the personal knowledge (what comes from the teacher as personal life, as corporeal felt and teaching desire) from the one who is official, presented in the official texts (school curricula, institution of school reference and project of establishment).

Research Participant
A male and beginner teacher named "teacher C" voluntarily participated in this study.He taught PE in secondary school for 2 years.He is specialist of gymnastics, see Table 1 and agrees to teach two different PSA, that is three sessions of the cycle of gymnastics and three sessions of the cycle of basket-ball.

Data Collection
The filming took place between the 28 th of January, 2014 and the 16 th of August, 2014.Before the first interview "a priori", a first visit allowed us to list, with the teacher, the available space and material (the state of place).
The data analysis is organized around three phases of the clinical didactic methodology of the PE systematically used: − Before the session: this time corresponds to a priori analysis of the "already-there experiential et conceptual" of the teacher through the analysis of his link to PSA (interview a priori) and to knowledge to be taught in gymnastics and basketball (interview "ante" session and analysis of theoretical contents of sessions).− During the session: it is the time of knowledge transmission event.The filming and the transcription of the video recordings allow here to analyze what takes place effectively in situ.− After the session from the interview of "after event", a moment when the teacher explains his version of the progress of the various sequences and the sense that he attributes to his practice and to the transmitted knowledge.Data were collected using the video observation (filming) and interviews: a priori, ante session, post session and "post stroke".Our corpus constituted of audio and video recordings of a PE teacher leading the second, the third and the fourth basket-ball and gymnastics session.We refer to the clinical didactic methodology.This methodology is organized with three distinct times constructed temporality: the "already-there", the "test" and the "post stroke" (Terrisse, 2000).Consequently, we take in account in priority and in postoriority what singularizes the processes of learning-teaching and the professorial activity from epistemological and didactic point of view.

Data Analysis
For the data analysis, we refer to the clinical didactic methodology organized around three analysis phases systematically used: before, during and after the teaching act and the data triangulation process.We used also the retranscription of verbatim and the analysis of the clinical interview, the content's analysis (Van Der Maren, 1996;Bardin, 1998) and the analytical reading (Starobinski, 1970).

The Case of Specialty Teaching
Personal link to PSA: the gymnastics is very significant for the teacher C arousing in him several feelings which are sometimes contradictory: such us personal interest, sacrifices, suffering and pleasure.His personal link to this activity marked him strongly: "teaching gymnastics is a pleasure for me, I like do it, it's my sports specialty, I don't care about" 1 .Personal conception of teaching: specifically, during the teaching of the sports specialty (gymnastics), the teacher exposed and recognized knowledge which is connected to his personal link to knowledge and personal experience such as the gymnastic posture, that is confirmed in the interview of "post stroke": "I felt that I teach something which is in me, that I already have, my gymnast's posture".This personal knowledge is particularly a part of his "sports lived" and recovers from this fact of process of formalization and personal integration of knowledge.
Personal link to body: in this study, we take into account the link to body as the constituent element of the personal expertise of the teacher as both a specialist and a determiner of his teaching process.Indeed, expert teacher transmits a corporeal knowledge.He uses essentially the direct physical ostension (DPO) total or partial (Salin, 2002;Sghaier et al., 2016) stemming from his corporeal expertise to expose the knowledge to pupils.He transmits incorporated and personal knowledge.From Table 2 and Figure 1 presented below, we can discuss that the teacher C uses differently the ostensive forms.Indeed, he refers to the direct physical ostension (corporeal demonstration) in the teaching of sports specialty.However, when he teaches the second PSA (the non-specialty or basket-ball) he refers especially to the direct verbal ostension (DVO).Furthermore, his corporeal practice influences the nature of ostensive forms used and his knowledge proximity.
The Advance of knowledge and the link to contingency: globally, the specialist teacher thinks about knowledge to be transmitted to his pupils: "for me, I have never smelt any difficulties in gymnastics; I can anticipate what is going to take place with my pupils, I think about my teaching".So, he is in the anticipation.Interestingly, Table 2. Ostensive procedures used in gymnastics and basket-ball.he decodes the pupils' practices thanks to his own knowledge in the activity.Indeed, the expert teacher has also singular strategies of contingency allowing him to manage the breaks of the didactic contract (manage the didactic contract ruptures) by referring to the personal knowledge and to the personal forms of ostension.Thinks to his specific link to contingency, he assumes his didactic responsibility for the advance of knowledge and the mastery of pupils (class management) in class.It is not the case when the teacher discovers at the same time as the pupils these difficulties and he cannot resolve them for lack of adaptation (adaptation fault).As a result, teacher C is regarded as professional in education (Altet, 1991;Paquay 1994), with expertise and effectiveness in terms of adaptation, autonomy and reflection (Schӧn, 1994(Schӧn, , 1996;;Berliner, 1986;Siedentop et al., 1989).In fact, reflexive practice allows teachers to improve their professional conduct (Kpazai & Attikleme, 2012;Legault, 2004;Sebren, 1995;Smyth, 1984).

The Case of Non-Specialty Teaching
Official link to PSA: The teacher C presents basket-ball as an "aggressive, complicated and binding" PSA which is practiced in an "uncertain and variable milieu": "I don't like teaching basket-ball, it is not my trick, I don't know it enough…Eh… but I must do it".His official link to PSA characters his speech.For him, teaching the basket-ball is an institutional constraint.
Official conception of teaching: the nature of knowledge transmitted in the teaching of the non-specialty allows us to show the dominant part of the official knowledge marking the transmission process.Indeed, the lack of personal experience and corporeal practice in the activity leads (conduit) the teacher to refer to the official knowledge while staying in his simple planning to preserve class didactic mastery, especially when he is novice in the professional practice: "I transmitted the technical fundamental gestures with and without ball mentioned in the programs".Therefore, we notice, particularly, an official conception teaching on the teaching of the second activity.
A different link to contingency: contrary to the adaptation process marking the link to contingency in specialty teaching, the teacher expresses his fear of the unforeseen, the loss of mastery and his difficulty supporting the class situation contingency.Indeed, he does not know how to solve the unforeseen problems connected to the pupils' apprenticeship: "sometimes I can't solve the problem because I can't find the solution".So, this distance to his planning prevents him to venture into a contingency, which could not be managed and shows his immediate link to knowledge.

Discussion
This paper discusses the impact of the personal experience and the sportive expertise on the teaching activity.We argue that the subjective resources in terms of personal link to knowledge, personal link to PSA, personal link to contingency and personal link to body affect the practice teaching of PE and determine the teaching conceptions (Buznic, 2009;Jourdan in Terrisse et al., 2009).However, we do not intend to generalize our results because it is about a single case study.Our analysis becomes attached to the fact that the most singular of a personal experience can show any universal human condition through a generic frame of invariants applicable, in the professional training context, to a certain extent to every teacher (novice, experimented, specialist or not) confronted with different PSA teaching.

Conclusion
As a conclusion, this comparative didactic analysis shows that personal experience influences the teaching act and the professional practice.Indeed, the personal experience, in terms of personal "reflection" of "thinking", appears to contribute to the raising of awareness of the teacher's "social role as a professional" (Kpazai & Attikleme, 2012).Taking into account the personal dimension of teaching is, in contemporary society, an indicator of professionalism in teachers because this dimension makes them real educative actors.Therefore, the scientific research needs to develop tools that permit the optimization of professional training of PE teachers.There is a need for professional training institutions to develop the conditions that underpin innovation.As noted above, to moving from the specific (case study) to the general, this research demonstrates that thinking in the pursuit of professional training optimization appears to be an emerging process.However, if professional expertise allows us to think that teaching as a "personal thinking", other elements as the impact of the teaching on the pupils learning could constitute in the pursuit of this way of research.
