You have probably seen both types of teams. Team A: players who are
evenly spaced, calling out plays, staying in their positions only to
watch them dribble the ball out of bounds, lose the pass, or shoot
wildly at the goal. Team B: amazing ball control, skillful shooting and
superior quickness, speed and agility but each player is a
"do-it-yourselfer" since no one can remember a formation, strategy or
position responsibility. Team A knows WHAT to do, but can't execute.
Team B knows HOW to do it, but struggles with making good team play
decisions. This is part of the ongoing balancing act of a coach. At the
youth level, teaching technique first has been the tradition, followed
by tactical training later and separately. More recently, there has
been research on the efficiency of learning in sports and whether there
is a third "mixed" option that yields better performance.
Earlier, we took an initial look at as an introduction to this discussion.
In addition, Dr. Markus Raab of the Institute for Movement Sciences and Sport, University of Flensburg, Germany,
(now of the Institute of Psychology, German Sport University in
Cologne), took a look at four major models of teaching sports skills
that agree that technical and tactical skills need to be combined for
more effective long-term learning.Each of the four models vary in their
treatment of learning along two different dimensions; implicit vs.
explicit learning and domain-specific vs. domain-general environments.
Types of Learning
Imagine two groups of boys playing baseball. The first group has gathered at
the local ball diamond at the park with their bats, balls and gloves.
No coaches, no parents, no umpires; just a group of friends playing an
informal "pick-up" game of baseball. They may play by strict baseball
rules, or they may improvise and make their own "home" rules, (no
called strikes, no stealing, etc.). In the past, they may have had more
formal coaching, but today is unstructured.
The second group is what we see much more often today. A team of players, wearing
their practice uniforms are driven by their parents to team practice at
a specific location and time to be handed off to the team coaches. The
coaches have planned a 90 minute session that includes structured
infield practice, then fly ball practice, then batting practice and
finally some situational scrimmages. Rules are followed and coaching
feedback is high. Both groups learn technical and tactical skills
during their afternoon of baseball. They differ in the type of learning
they experience. The first group uses "implicit" learning while the
second group uses "explicit" learning. Implicit learning is simply the
lack of explicit teaching. It is "accidental" or "incidental" learning
that soaks in during the course of our play. There is no coach teaching
the first group, but they learn by their own trial and error and
internalize the many if-then rules of technical and tactical skills.
Explicit learning, on the other hand, is directed instruction from an
expert who demonstrates proper technique or explains the tactic and the
logic behind it.
An interesting test of whether a specific skill or piece of knowledge has been
learned with implicit or explicit methods is to ask the athlete to describe or verbalize the
details of the skill or sub-skill. If they cannot verbalize how they
know what they know, it was most likely learned through implicit
learning. However, if they can explain the team's attacking strategy
for this game, for example, that most likely came from an explicit
learning session with their coach.
Types of Domains
The other dimension that coaches could use in choosing the best teaching
method is along the domain continuum. Some teaching methods work best
to teach a skill that is specific to that sport's domain and the level
of transferability to another sport is low. These methods are known as
domain-specific. For more general skills that can be useful in several
related sports, a method can be used known as domain-general. Why would
any coach choose a method that is not specific to their sport? There
has been evidence that teaching at a more abstract level, using both
implicit and explicit "play" can enhance future, more specific
coaching. Also, remember our discussion about kids playing multiple sports.
Based on these two dimensions, Dr. Raab looked at and summarized these four teaching models:
TGFU
The TGFU approach, (best described by Bunker, D.; Thorpe, R. (1982) A model for the
teaching of games in the secondary school, Bulletin of Physical Education, 10, 9–16), is known
for involving the athlete early in the "cognition" part of the game and
combining it with the technical aspect of the game. Rather than learn
"how-to" skills in a vacuum, TGFU argues that an athlete can tie the
technical skill with the appropriate time and place to use it and in
the context of a real game or a portion of the game. This method falls
into the explicit category of learning, as the purpose of the exercise
is explained. However, the exercises themselves stress a more
domain-general approach of more generic skills that can be transferred
between related sports such as "invasion games" (soccer, football,
rugby), "net games" (tennis, volleyball), "striking/fielding games"
(baseball, cricket) and "target games" (golf, target shooting).
Decision Training
The DT method, (best described by Vickers, J. N., Livingston, L. F.,
Umeris-Bohnert, S. & Holden, D. (1999) Decision training: the
effects of complex instruction, variable practice and reduced delayed
feedback on the acquisition and transfer of a motor skill, Journal of
Sports Sciences, 17, 357–367), uses an explicit learning style but with
a domain-specific approach. Please see my earlier post on Decision Training for
details of the approach.
Ball School
The Ball School approach, (best described by Kroger, C. & Roth, K.
(1999) Ballschule: ein ABC fur Spielanfanger [Ball school: an ABC for
game beginners] (Schorndorf, Hofmann), starts on the other end of both
spectrums, in that it teaches generic domain-general skills using
implicit learning. It emphasizes that training must be based on
ability, playfullness, and skill-based. Matching the games to the
group's abilities, while maintaining an unstructured "play" atmosphere
will help teach generic skills like "hitting a target" or "avoiding
defenders".
SMART
Dr. Raab's own SMART model, (best described in Raab, M. (2003) Decision making in
sports: implicit and explicit learning is affected by complexity of
situation, International Journal of Sport and Exercise Psychology, 1,
406–433), blends implicit and explicit learning within a
domain-specific environment. The idea is that different sports'
environmental complexity may demand either an implicit or explicit
learning method. Raab had previously shown that skills learned
implicitly work best in sport enviroments with low complexity. Skills
learned explicitly will work best in highly complex environments.
Complexity is measured by the number of variables in the sport. So, a
soccer field has many moving parts, each with its own variables. So,
the bottom line is to use the learning strategy that fits the sport's
inherent difficulty. So, learning how to choose from many different
skill and tactical options would work best if matched with the right
domain-specific environment.
Bottom-Line for Coaches
What does all of this mean for the coach? That there are several different
models of instruction and that one size does not fit all situations.
Coaches need an arsenal of tools to use based on the specific goals of
the training session. In reality, most sports demand both implicit and
explicit learning, as well as skills that are specific to one domain,
and some that can transfer across several sport domains. Flexibility in
the approach taken goes back to the evidence based coaching example we gave last time.
Keeping an open mind about coaching methods and options will produce better prepared athletes.
