The Effect of Interfering Waves Strategy in Developing Some Basic Volleyball Skills for Intermediate First Graders

Abstract

The research objectives to reveal the effect of using the interfering waves strategy in learning some basic
skills in the game of volleyball (serve from the bottom facing, receiving the serve from the bottom, and
preparing from the top) for the first intermediate students, the researchers used the experimental method,
and the research sample consisted of (32 A student with (16) students in each group, and by lottery two
groups were named to represent one of them the experimental group and the other the control group,
and parity was achieved between the two groups in the variables (age, weight, and height) in addition to
achieving parity between them in basic skills (under study), And the overlapping waves strategy was used
with the experimental group players, but with the control group, the method was used by the trainer, and the
implementation of the experiment took nine weeks with two educational units per week for each group of
18 educational units, and the time for one educational unit was (45) minutes, and the experiment started on
10/2/2018 until 1/15/2019.
The researchers used the following statistical method: the mean, standard deviation, simple correlation
coefficient (Pearson), (t) test for two related means and two equal samples, and (t) test for two unrelated
means and two equal samples. And after analyzing the data statistically, the researchers reached conclusions,
the most important of which are:
1. The use of the overlapping waves strategy had a clear role in learning some basic skills (under study)
for the experimental group players.
2. Take advantage of the overlapping waves strategy in physical education lessons for all school levels.
