Does One More Time Verbalization’s Sequence Increases the Progression of Motor Learning

This work studies the effect of the verbalization sequences constructed by the pupils during a cycle of eight basketball sessions in Physical Education and Sport (PES) on motor learning for a mixed class of Tunisian high school pupils. On the one hand, we compare the effects of pupil’s discursive productions after a first and a second sequence of verbalization. On the other hand, we consider the differences in the action projects between the language interactions of girls, boys and mixed groups. The observation is used as data col-lection instruments. The didactic interaction is studied by exercising the quantitative approach to identify hidden intentions. The measured parameters are: played balls, shots and scored baskets. The results of the experiments showed that the practice of learning in condition with verbalization brings positive effects in terms of behavioral modification. The addition of a second sequence of verbalization during the same session is more effective for the learning than the practice under condition of a single sequence application. We sug-gest to Tunisian PES teachers to give more time to verbalization, pupils learn better after identifying the mechanisms that lead to the success of their action projects and have a more pronounced rate of learning.

This work examines the importance of the introduction of language interaction sequences produced by pupils during the learning sessions in physical education and sport (PES). Through this manuscript we propose a model of socioconstructivist learning based on the concept of "socio-cognitive conflict". This model anchored in constructivism emphasizes social interaction as an effective way to improve knowledge and help build human intelligence. Such work can make an interesting contribution to the sciences of the intervention in pedagogical and didactic terms in the field of PES. Indeed, PES is an integral part of the Tunisian education system. Tunisian pupils take two to three hours of PES per week during their primary and secondary school. These sessions are mixed; they are structured in disciplinary learning cycles. The aim of this study is to take into account the pupils' point of view and how they co-construct their knowledge in and through action (Zghibi et al., 2013a).
Several literature reviews have examined the effects of verbalization by the pupils on his motor learning in contexts and with different aims of verbalization. In dance, (Lafont & Martin, 2014) demonstrated that the verbal production of a sequence observed by young pupils was effective only if the teacher had previously had recourse to the explicit demonstration, that is to say If he had accompanied his demonstration of verbal information (comments, explanations). In the same context, Weiss, Ebbeck andRose (1992, cited by Cadopi, 2005) worked on younger pupils aged 5 to 10 years (verbal explanation without demonstration and/or direct reproduction of the sequence without verbal repetition). These authors have suggested that the pupil verbalize in order to elaborate a representative coding and an internal reference allowing him to reproduce the sequence demanded by the teacher, but also to evaluate those that he executes (Cadopi, 2005). Another research conducted by Elandoulsi (2006) has demonstrated positive effects on the motor acquisition of a gymnastic gesture. Similarly, in team sports such as volleyball (Keukelaere, Guérin, & Saury, 2008), In handball (Darnis & Lafont, 2008, 2013 showed that the effect of verbalization was more effective in male dyads (Darnis-Paraboschi et al., 2005) and asymmetric dyads in favor of the less competent pupils (Darnis & Lafont, 2008, 2013. As a discourse in an educational setting, verbal production or negotiation is the set of observable statements produced between pupils. These negotiations aim to improve the game of pupils in a collective sport learning cycle (basketball) in the educational context of PES. Social inequality between girls and boys can play a key role on the team sport in the learning process based on the verbalization between pairs. In this perspective, this study highlights the effect of language interaction on the behavioral progression change in high school pupils during learning of collective sport.

Methodology
The didactic situation proposed in this study consists in allowing a time of discursive interaction in the form of a "debate of ideas" (Grehaigne & Godbout, 1995;Gréhaigne, 2009) between pupils (5 × 5, 3 teams, boys team, girls team and third mixed team girls and boys aged 17), with/without the teacher, before/after a game (T = 3 × 8') in a basketball court (Zghibi, 2009). Each team is composed of 7 players (5 participants and 2 substitutes); the mixed team must play with (3 boys and 2 girls).
The data were collected using an observation grid. The observed indicators are: the balls being played (play volume), the shots and scored baskets (offensive capacity) (Gréhaigne et al., 1989). These results will be presented in groups.
Each session is composed of three game situations (T = 8'), under the teacher's control, interspersed with two verbalization sequences (t = 3'), one in the presence of the teacher and another in his absence, consisting of narrating the facts and arguing about a collective strategy.

From before to after Sequence 1
Data collected during the eight game before and after the first sequence of verbalization (boys) are presented in Table 1. For boys, the number of played balls increased remarkably at the end of the learning cycle (sixth, seventh and eighth session) with a difference of 03 balls played between the two sets separated by the verbalization sequence ( Figure 1).
Regarding the number of shots to the basket showed degradation from before to after verbalization during the first half of the cycle especially for the third session (from 8 to 1 shot) and begins to evolve from the fifth session with a range of progression from 2 to 7 shots ( Figure 2).
The number of scored baskets fluctuated from the first to the fifth session. This parameter has improved over the last three sessions of the learning cycle (sixth, seventh and eighth session) with a difference of 2 and 3 scored goals per session after verbalization ( Figure 3).   Data collected during the eight games before/after the first sequence of verbalization (girls) are presented in Table 2.
For the girls, the recording of the played balls is devoid of degradation. This parameter remained constant for the sessions (3 and 5) and improved for the sessions (1, 2, 4, 6, 7 and 8). The extent of progression ranging from 1 to 4 ( Figure 4).
The number of shots showed a fall during a single session (2) where it increased from 8 before the sequence of verbalization to 6 after this sequence. For the rest of the cycle is characterized by a progressive evolution from 1 more shot for the sessions (1 and 3), 2 more shots for the sessions (4, 5 and 6), 3 more shots for the session (7) and 4 more shots for the last session (8) ( Figure 5).
The number of recorded baskets is improved in a remarkable way along the learning cycle except for the only session (3) it remains constant. This improvement showed an evolution which extends from 1 to 5 from before to after the verbalization sequence ( Figure 6).
Data collected during the eight games before/after the first sequence of verbalization (girls/boys) in Table 3.
For boys/girls group, the number of played balls increased remarkably along the learning cycle except for session (2) it remains constant and during session (1) decreased from 19 before verbalization to 17 after verbalization. The extent of progression is fixed at 1 for the session (3) to 5 more balls played for the session (8) (Figure 7).
Regarding the number of shots to the basket showed degradation from before to after verbalization during the first half of the cycle. This parameter has begun to evolve from the fifth session with a range of progression from 1 to 3 shots      throughout the cycle with an extensive progress that has fluctuated between 1 and 3 scored goals over after verbalization (Figure 9).

From before to after Sequence 2
Data collected during the eight game before and after the second sequence of verbalization (boys) are presented in Table 4. Improving the level of played balls after the second sequence of verbalization was present from the beginning to the end of the cycle. This offensive parameter showed a considerable margin of progression that ranges from 1 to 6 ( Figure  10).
Regarding the number of shots to the basket showed degradation from before to after second sequence of verbalization during the first half of the cycle and  Session 8 Before 22 9 5 After 28 12 10 Figure 9. Scored basket's number during the eight games before/after the first sequence of verbalization (girls/boys).
begins to evolve from the fifth session with a range of progression from 1 to 8 shots ( Figure 11). The number of scored baskets has improved over the learning cycle with a difference of 1 and 5 scored goals per session after second verbalization ( Figure  12).    Data collected during the eight games before/after the second sequence of verbalization (girls) are presented in Table 5.
For girls, the number of played balls increased remarkably over the learning cycle. This parameter evolved during the first half of the cycle with a minimal range of progression which ranged from 1 to 2. For the second half, it was established with a range that fluctuated from 5 to 7 (Figure 13).  Figure 13. Played ball's number during the eight games before/after the second sequence of verbalization (girls).

Played ball After verbalization
Concerning the number of shots to the basket showed degradation from before to after second sequence of verbalization during the first half of the cycle and begins to evolve from the fifth session with a range of progression from 2 to 3 shots (Figure 14).
The number of scored baskets has improved over the learning cycle with a difference of 1 and 5 scored goals per session after second verbalization ( Figure  15).
Data collected during the eight games before and after the second sequence of verbalization (girls/boys) are presented in Table 6.
For boys/girls group, the number of played balls increased remarkably from session (3) to the end of cycle from 1 to 6 after second sequence of verbalization ( Figure 16).    Session 8 Before 20 7 5 After 26 10 9 Figure 16. Played ball's number during the eight games before/after the second sequence of verbalization (girls/boys).
The number of shots to the basket has improved over the learning cycle (from second session) with a difference of 1 and 3 scored goals per session after second verbalization ( Figure 17).
The number of scored baskets has improved over the learning cycle with a difference of 1 and 4 scored goals per session after second verbalization ( Figure  18).

Discussion
Teacher is always in perpetual search for facilitating the action of teaching, the transmission and acquisition of knowledge. In this context, it makes use of the strategy of verbalization which still remains untapped in the Tunisian education sector in terms of PES.
In this perspective, this study highlights the effect of language interaction on the behavioral progression change in high school pupils during learning cycle of collective sport such as basketball.
The results of the experiments showed that the practice of learning in condition with verbalization brings positive effects in terms of behavioral modification. The addition of a second sequence of verbalization during the same session is more effective for the learning than the practice under condition of a single sequence application.
Our findings are consistent with (Zerai et al., 2008, Chang, 2009, Zghibi, 2009) who have reported that the introduction of collective sport verbalization has a beneficial effect on student investment in motor Learning. It seems that the role of the information added by the verbalization during a second sequence of verbalization led students to better interact and produce qualitative indications on the characteristics of the action. The importance of transition information (strategic information about what needs to be done in the next game) provides the best knowledge in terms of future student activities and the promotion of motor learning.
Motor learning is organized and controlled by essentially cognitive processes (Alibali et al., 2000;Bastien, 1987) with divergence in the degree of awareness (Chikoko, 2007;Biao, 2013). Fleurance (1991) affirmed that there is a part of knowledge, of the necessary awareness of motor learning which evolves rapidly in favor of an infra-conscious cognitive process. In the same context, (Bouthier, 1988;Grehaigne et al., 1989) suggested that the approach based on the awareness of action rules through verbalization seems the most relevant to meet the aims of the PES.
The results suggested that requiring students to communicate with each other after each game makes it possible to modify their responses in an evolutionary way with progression ranges from minimal (after the first sequence) to important (after the second sequence). The degree of evolution was more marked in the boys than in the girls especially for the parameters played balls (volume of the game) and scored baskets.
The offensive parameters measured in this study showed fluctuations (ups and downs) after the first sequence of verbalization. Boys seem to be more sensitive to verbalization sequences than girls (Zghibi et al., 2013a(Zghibi et al., , 2013b(Zghibi et al., , 2014 both after the first and second sequences. Zghibi et al. (2014) declared that girls appear to be involved in the discussion, their statements are less numerous, and their analytic statements less effective than those of boys.
An additional sequence of verbalization presents a strategy to support the development of knowledge in collective sport (Wallian & Chang, 2007a, 2007b in order to improve the action projects of players and teams both for boys and girls. This strategy contributes to the development of reinvestable resources (attitudes, motor skills) (Nachon, 2004) and allows students to compare their information and knowledge in order to complete and reconsider their representations in order to improve the effectiveness of their actions.
Verbalisation is a phenomenon of constructivist negotiation (Bronckart, 1997; in the learning of collective sports. Discussion is central to learning (Cottinet and Harmand, 2003), which provides feedback on whether or not to admit the team's action plan by returning to the strategy (Grehaigne, 1996).
The key role of verbalization and explanation, regardless of learning stage or gender (Grehaigne and Godbout, 1995), allows learning situations to evolve in the direction of increasing efficiency, Commitment and active search for solutions on the part of pupils. It is legitimate to note certain limits to this study. We have not given interpretation to the qualitative analysis of linguistic productions of girls and boys, a survey on this issue is necessary to focus on the relationship between words and action. Crossing the qualitative and quantitative analysis allows us to have more detailed findings.

Conclusion
In a framework of socio-constructivist approach to motor learning (Wallian & Chang, 2007a), the allocation of more time to verbalization (Grehaigne, 2009) regardless of stage or condition of learning (group girls, Boys or mixed), pupils learn better after identifying the mechanisms that lead to the success of their action projects and have a more pronounced rate of learning. The study also supports the work of (Zghibi et al., 2014) who suggested a redefinition of the divisions of social roles according to gender in the Tunisian educational context of collective sports in terms of PES.
