Volleyball is one of the games that the scientific method contributed to
organize and develop its components, which contributed to raising the
level of the game in terms of training and players. Where the players are
the nucleus of the game. Therefore, the process of selecting them from
an early stage helps in developing all their physical, physiological, skill,
and planning, cognitive and psychological indicators. As these indicators
are affected by influences and external factors that directly affect the
process of training, and one of these influences and external conditions
is the environment and its various aspects. Therefore, the research
problem manifested by the effects of environmental variables and the
extent of its impact on some physical indicators among the volleyball
players under the age (18 years) as a result of playing the game under
different circumstances in different areas of Iraq. Descriptive design in
the comparative study method was used, the participants were 41
players selected by random class style from sports clubs under the age
of 18. A set of statistical methods have been used to analyse data and
achieve the study objectives. The research found that there were
significant differences in the selected physical indicators and in different
degrees between the northern and central regions. In light of this, some
recommendations have been made that help to raise the level of training
.on the basis of training period and areas

The research included its introduction and its importance and was
addressed to find standard levels of administrative work ethics for the
.teachers of sports education in Diyala province
To be a guide that helps educators assess the ethical abilities of
teachers. The problem with research is the lack of studies showing the
standard levels of administrative ethics of teachers of sports education.
By building standard levels that reveal the levels of each teacher and are
full of a solution to the problem. The research aims to build standard
levels of administrative work ethics towards the study of sports education
for some middle school principals in Diyala province. The areas of
research included the human field of sports education teachers in Diyala
province. The temporal area (7/1/2029_20/20/2020) and the spatial area
of middle schools in Diyala province. The researcher used the
descriptive method in the survey method to suit the nature of the
problem. The research community included (281) teachers of sports
education. The same research consisted of (140) teacher and teacher
and the sample was chosen in a random way and then the scale was
applied to the sample of the research consisting of (31) expressed
(9/1/2020_13/2/2020) and the answers of the sample were corrected and
the use of statistical bag (spss) to find the appropriate degree and
standard levels. The researcher concluded the standard levels and
grades of the level of administrative work ethics towards the education
lesson. I recommend the adoption of standard levels and grades
recommended by the researcher in the evaluation and dissemination of
teachers

Brain-based learning theory represents a comprehensive approach to teaching
and learning that makes students more productive, and teachers less frustrated.
Also, this theory is based on the structure and function of the brain, as long as
the brain has not been prevented from performing its natural processes, learning
will happen, and it is not only supported by neuroscience, but it is also supported
by cognitive psychology research, so research based on linking brain science
with psychology Cognitive increases the understanding of the basic processes of
learning and memory, as subtle thinking plays a vital role in the success of
individuals and their progress inside or outside educational institutions because
their performance in educational academic tasks, tests, and life situations are the
products of their thinking, according to which the extent of their success or
failure is determined. Dexterous gives a sense of conscious control over
thinking, which is reflected in improving the level of performance and selfconfidence, and the skill of overwhelming hitting is a difficult and complex skill
in volleyball, as the difficulty of this skill is difficult for some students who are
educated to perform this skill with high mastery, and the importance of research
lies in Weakness and fluctuation in the level of performance of the
overwhelming hitting skill by students. This reason is due to the students' lack of
mental, cognitive and behavioral abilities that have an effective impact on the
performance of this skill, and its importance also lies in it being in line with new
theories calling for adapting educational attitudes Familiar with the nature of the
brain, the most prominent of these theories is the theory of learning based on the
brain.
Therefore, the researcher decided to study this problem and learn the strengths
and weaknesses of students and shed light on the theory of harmonious learning
with the brain to know its effective role and its importance in the educational
process as well as the role of this theory in developing the skill of thinking,
especially skilful thinking and learning the skill side and in particular learning
the skill of overwhelming hitting with volleyball undersearch.

The researcher used the experimental approach in the method of the
experimental and control groups, and the research sample included (40) students
from the second stage in the College of Physical Education and Sports Science -
Diyala University for the academic year 2018-2019 and the results of the
research showed that the educational curriculum prepared according to the
theory of learning consistent with the brain proved Its importance and its
effective effect in raising the degree of subtle thinking and learning the skill of
overwhelming hitting the volleyball under discussion, especially in the technical
performance level tests and accuracy tests of the research sample and better than
the curriculum followed in the college. Completing the research requirements,
the researcher provided a set of recommendations, attention to developing
educational curricula and including them in programs to develop the mental
abilities of students, especially skilled thinking, especially in the first and second
stage because smart thinking comes as a result of training and experience, and
the use of the educational curriculum according to the theory of learning
consistent with the brain in learning the skill of hitting the ball The plane is for
second-stage students in the colleges of physical education and sports science in
Iraqi universities because of its active role in learning the basic skills under
discussion.

The present study consisted of five chapters. The first chapter is an introduction
As the technical and legal development in the handball game was addressed, as
well as the method of using the computer and its importance in evaluation and
measurement, whether the player or the team, in matches or training , The study
aims at Designing an analytical program to evaluate the effectiveness of skill
performance in handball , Knowing the relationship between the skill
performance and the ranking of the Premier League handball teams , the
hypothesis of research The existence of a statistically significant relationship
between the 61ffectiveness of the skillful performance of the Premier League
handball team ranking.
The study methodology and field procedures.The descriptive approach was used
on a sample of (11) clubs representing the Iraqi Premier League clubs in
handball, as well as designing and preparing a statistical analysis program, then
explaining the method of its use, as well as conducting the exploratory
experiment in addition to the main experiment on the first stage of the league
and then using statistical means. This chapter included displaying the statistical
description of the variables by extracting the arithmetic mean, median and
deviation, then extracting the coefficient of the rank correlation of the league,
and then discussing these results. The designed analytical program has achieved
its intended purpose in analyzing the effectiveness of skill performance using
the electronic calculator quickly and using it correctly It is necessary to provide
a specialized statistical program at the Iraqi Central Handball Federation in
order to work on analyzing and extracting the results of the team and converting
them from events on the field and skills to specific numbers of values and
significance in a way that serves the game of Iraqi handball
