Bilateral Transfer of Learning
A study in Classical Ballet
Purpose and relevance

Porto, 2012

Dance performance is often associated with the practice of specific technical skills.

It is expected dance students to be able to perform in a simetrical way.

movement accuracy
injury prevention
(Steinberg et al., 2012)
When children initiate dance practice there is a discrepancy in motor skills, namelly in terms of laterality.

An unexperienced dancer tends to demonstrate a clear preference for learning and practice skills on a particular side (Kimmerle, 2010).

The purpose of the present study was to study bilateral transfer of leraning (BTL) in classical ballet classes development of training techniques to promote movement symmetry.
Bilateral Transfer of Learning
The practice of a motor task with a body segment optimizes learning and performance of the homologous contralateral segment (Magill, 2011).

BTL is widely mentioned in research literature, in particular regarding the reasons why it occurs, or the direction of transfer
In classical Ballet, the teaching methodology tends to rely on the demonstration and practice of movements and technical elements on the right side, usually the preferred side. After learning and initial practice of a particular skill, students are expected to transfer it to the non-preferred side.

To exlpore whether the amount of learning transfered is symmetrical or asymmetric, [from the preferred member (PM) to the non-preferred member (NPM) or vice versa].

To study how the practice should be conducted in order to achieve the optimum performance of a specific motor skill (Vasconcelos, 2006).
In the context of the Classical Ballet, and despite the relevance of the BTL study as an instrument for performance optimization, there is not much research on this subject.
contribute to the body of knowledge regarding BTL;
to provide information that supports the adoption of classical Ballet teaching and practice strategies;
optimization of the training process.
Sample: 34 female right-handed children, aged from 6 to 11 years old (8.76 ± 1.52 years).

Dutch Handedness Questionaire (van Strien, 2002) e Lateral Preference Inventory (Coren, 1993).
The author and an accredited RAD teacher designed a questionnaire to evaluate exercise performance.

for preparing the questionnaire: RAD's vision and objectives (RAD, 2011).
Evaluation parameters:
technical capacity (posture, alignment, coordination and balance), music (timing, response time) and performance (expression and communication).
Lickert scale of 1 to 5 points; qualitative evaluation: "very poor (1), poor (2), sufficient (3), good (4) and very good (5)".

All performances were recorded on video. The videos were subsequently analyzed by two judges.
The task consisted in performing two exercises from Royal Academy of Dance (RAD) former curriculum.

Students were
randomly assigned
to one condition;

was performed by an accredited RAD teacher;

In both treatment conditions, each student made 5 attempts in the learning phase, 5 in the retention phase and 1 attempt in the final evaluation (learning transfer stage), in which each participant performed the exercise to the opposite side to which they practiced, deprived of any additional instruction;

Learning transfer value
: average of the two evaluators' scores on the technical, music and performance parameters at the stage.
Software S.P.S.S. - 20.0 version;

Descriptive statistics

Multivariate ANOVA to examine the effect of age and practice condition factors on BTL;

Level of significance: p ≤ 0.05;
Final score (BTL) in relation to the age
Final score (BTL) in relation to condition of practice
Results - Technique

Results - Musicality

Performance score in relation to the condition of practice
effects of the transfer condition, with higher transfer values in the NPM to PM direction;

effects of the age factor, with higher values of transfer in older dancers;

effects on the interaction of transfer condition and age variables.

The creation of an instrument that measures BTL through performance,

To increase the number of attempts in the acquisition and retention phases of motor learning, taking subjects' ages into consideration;

Increasing the sample size, covering other age groups and higher levels of expertise - investigating variations in the direction or quantity of information transferred throughout development;

To study the BTL and its relation with the manual preference, namely in left-handed or ipsilateral subjects;

To study the BTL in the Classic Ballet according to the sex;
