PSEB 12th Class Physical Education Notes Chapter 6 Sociological and Psychological Aspects of Physical Education

→ It is a well-known fact that man is a social animal by nature and possesses innate social tendencies to create a conducive social environment around him.

→ The term ‘Sociology’ comprises of two words ‘Socius’ meaning associate or social and ‘logos’ meaning science or study.

→ Hence, sociology means the science of society.

→ According to Ogburn, “Socialization is the process by which the individual learns to conform to the norms of the group.”

→ Physical education and sports works as building blocks for inculcating the social qualities in an individual.

→ This field provides varied experience to learn social qualities such as character and moral qualities, group feeling and responsibility, punctuality and dedication and social communication, etc.

→ There are several social institutions that affect human behaviour in many ways such as family, educational institution i.e. school or college, etc, peer group, religious institution or national culture, etc.

→ Physical education and sports programme play a vital role in inculcating a deep understanding of cultural diversity, equal opportunities, respect for nation and patriotism, sense of responsibility, etc.

→ This ultimately serves as an important means to develop national integration among the countrymen.

→ The other aspect which has been discussed in this chapter is the psychological behaviour of a sportsperson and its impact on learning skills.

→ The word ‘Psychology’ has been derived from the Greek word ‘Psyche’ and ‘logos’ which means ‘soul or mind’ and ‘to talk about’ respectively.

→ Hence, psychology deals with the study of the human soul or mind in relation to their behavioural aspects.

→ In physical education and sports, the term sports psychology deals with the study of the behaviour of sportsperson in or outside the playfield.

→ It is very important to understand the behaviour of sportsperson when it comes to performance-oriented sports.

→ In addition to this, the behaviour of adolescents also needs to be recognized and understood for their proper growth and development.

This PSEB 12th Class Physical Education Notes Chapter 5 Disability will help you in revision during exams.

PSEB 12th Class Physical Education Notes Chapter 5 Disability

→ The term disability is the state of being unable to use any part of the body properly, which may be due to injury or disease.

→ This restricts an individual to perform daily activities with comfort and ease.

→ The special ability or disability can be either structural disability or functional disability.

→ There are various causes of disability i.e. it can be inherited or caused by environmental factors.

→ The environmental factors are very vast. it can be due to disease, occupation, physical factors, social factors, chemical factors or psychological factors and accidents, etc.

→ There are many occupational diseases that may cause disability to a person.

→ These occupational diseases can be due to physical agents like dust, noise, radiation, and dust or chemical hazards, etc.

→ These diseases can be prevented to some extent by various means such as medical examination of the workers, maintenance of workplace, control of air or noise pollution, use of protective devices, etc.

→ Another term that has been discussed in this chapter is rehabilitation which means, “the act of restoring something to its original or normal state.

→ The literal meaning came from the Latin words ‘re’-mean again and ‘habitable meaning ‘make fit’. It is the process of keeping a person who suffered an injur}’ or illness to come to a self-sufficient state.

→ There are many societies that are actively engaged for the rehabilitation services such as the Indian Red Cross Society, All India Blind Relief Society, Tuberculosis Association of India, Indian Council for Child Welfare, etc.

→ Hence, these societies help people to return to their normal or near-normal way of living.

This PSEB 12th Class Physical Education Notes Chapter 4 Sport Injuries will help you in revision during exams.

PSEB 12th Class Physical Education Notes Chapter 4 Sport Injuries

→ The term sports injuries mean the injuries that occur during participation in sports activities or exercising.

→ It is also quite common especially for the people who tend to be active or exercise a lot in their routine.

→ The injuries in the field of sports can be due to direct or indirect impact on tissues i.e. soft tissues or hard tissues.

→ In the field, an athlete has to take part in terms of the process or training, or competition and seek medical treatment or first aid for the same.

→ The injuries in the field of sports can be due to poor physical fitness level, inadequate warming up or conditioning, lack of proper knowledge, poor quality sports equipment, bad conditions of the playfield, lack of nutritional diet, etc.

→ The chances of injuries can be avoided by adopting various preventive measures such as participation after proper warming up and conditioning, use of protective equipment, proper knowledge of rules and regulations and techniques, under the supervision of a coach, etc.

→ It is also important to know the basic first aid procedure in order to reduce the chances of further complications at the time of injuries on the field.

→ The sports injuries such as sprain, strain, abrasion, contusion, dislocation, and fracture can be managed with the help of first aid procedure and basic principles of RICE (Rest, Ice application, Compression, and Elevation).

→ But, it is well said that “Prevention is better than cure”.

→ Hence, the principle of ‘PRICE’ is more suitable to avoid the chances of injuries in the field of sports, where ‘P’ stands for ‘Protection’.

→ Hence, for the continuous improvement in the performance level, it is important to take care of each and every aspect related to injuries and their management.

This PSEB 12th Class Physical Education Notes Chapter 3 Careers in Physical Education and Sports Awards will help you in revision during exams.

PSEB 12th Class Physical Education Notes Chapter 3 Careers in Physical Education and Sports Awards

→ Throughout history, sports have played a variety of important roles in society as recreation, preparation for war, and hunting.

→ The ancient Greeks were lovers of sports and taught their children to take part in these activities for health benefits.

→ The main activities at that time were wrestling, running, jumping, discus throw, javelin, and gymnastics, etc.

→ Later, during the modern era, the brief history of physical education revealed a focus on gymnastics, hygiene training, and the development of the human body.

→ In 1882, the Education Commission of India recommended introducing physical education in the school curriculum but did not succeed in their efforts.

→ In the year 1927, with the efforts of A.G. Noehren, H.C. Buck, and Dorabji Tata, IOA was established in order to promote physical education teachers in India.

→ LNCPE was established in Gwalior in the year 1957.

→ In the year 1984, the First National sports policy was introduced which laid the stress to include physical education as a compulsory subject in the school curriculum.

→ This laid foundation for the career options in the field of physical education to teach students at the school level.

→ With the implementation of the compulsory subjects in the school curriculum and with the development of competitive sports in India, career options were groomed in the field.

→ In order to teach at the school level various degree courses such as B.PE., B.P.Ed., D.P.Ed. were introduced for the school teacher.

→ In addition to this, to teach at the college level a teacher must possess, Masters’ Degree in Physical Education, UGC (NET), M.Phil, Ph.d.

→ With the advancement of physical education and sports in India, leading institutes provided various courses for the career options such as YMCA College Madras, LNIPE Gwalior, Shri Hanumans Parasarak Mandal (Amravati), Chennai University, Panjab University (Chandigarh), GNDU, Amritsar, etc.

→ The career options in the field of physical education and Sports also developed such as options to work as a school and college teacher, coaching, fitness trainer, sports journalism, sports physiotherapist, commentator, and official, etc.

→ In order to promote sportspersons, various sports awards were also introduced by the government of India such as the Rajiv Gandhi Khel Ratna Award, the highest sports award for the sports person i.e. Arjuna Award, in order to recognize the contribution of coaches, Dronacharya Award was also introduced, To encourage and improve sports at college or university level MAKA trophy was also introduced by the government of India in the year 1956.

→ Hence, It can be viewed that since the inception of physical education and sports, there has been continuous development in the field to engage youth and children in these activities.

This PSEB 12th Class Physical Education Notes Chapter 2 Sports Training will help you in revision during exams.

PSEB 12th Class Physical Education Notes Chapter 2 Sports Training

→ In today’s competitive world of sports, everyone aims at winning at all costs.

→ Hence, the concept of sports training has a vital role to play in the field of sports.

→ The concept of sports training deals with the systematic preparation of athletes to obtain peak performance at the time of competition.

→ The aim of sports training is to produce optimum performance during competition.

→ Hence, the training schedule is classified in such a way that a player gets complete recovery from the training load and feels fresh and energetic to take a fresh load to continue performance.

→ According to Martin, “Sports training is a planned and controlled process of achieving goals in which the changes of motor performance and behaviour are made through measures of content, method, and organisation”.

→ Hence, sports training implies a systematic and controlled way of imparting training to an athlete to produce an optimum performance at the time of competition.

→ In order to have fruitful results from the sports training programme various principles such as individual differences, the principle of use of disuse, load (overload), progression, safety, continuity, and rest or recovery must be followed, otherwise, the purpose of training will not be effective and useful for the trainees.

→ It is also important to perform the warm-up exercises to prepare an athlete physically, physiologically, or psychologically for the sports training programme or prior to competition.

→ It helps an athlete to perform with the least chances of injuries.

→ Similarly, limbering or cooling down plays a significant role to attain normal conditions after performing strenuous exercises.

→ Hence, sports training is the way and means of systematic training to develop various components of physical fitness to attain optimal performance during competition.

This PSEB 12th Class Physical Education Notes Chapter 1 Physical Fitness will help you in revision during exams.

PSEB 12th Class Physical Education Notes Chapter 1 Physical Fitness

→ The term Physical fitness has different notions for different segments of people.

→ It not only refers to being physically fit but also refers to a balanced state of mind.

→ A person can only be considered fit if he is able to function well without any undue fatigue or tiredness.

→ A person who is fit both on physical and mental aspects stays strong in every sphere of life.

→ Now, let’s discuss the definition of physical fitness.

→ It is the ability of an individual to work effectively and efficiently with joy and pleasure.

→ According to David R. Lamb, “Physical fitness is the capacity to meet the present and potential physical challenges of fife with success.”

→ In order to achieve the optimum level of physical fitness one must possess basic components such as strength, speed, endurance, agility, flexibility, and coordinative abilities.

→ If a person is having these components, then he will be considered to be physically fit.

→ But, there are various factors that may influence the physical fitness of an individual such as anatomical structure, physiological and psychological makeup, posture, diet, lifestyle, inactivity, injury, age and gender, etc.

→ So, these factors are responsible to have a major influence on the physical fitness of an individual.

→ Hence, physical fitness plays a vital role to live healthy, prosperous, and conducive life in the present scenario of technological advancement.

→ It helps in the proper growth and development with the efficient functioning of the physiological systems in the body.

→ These developments ultimately induce the feeling of a balanced state of mental health and physical health of a person.

This PSEB 10th Class Science Notes Chapter 2 Acids, Bases and Salts will help you in revision during exams.

→ The sour taste of foods is due to acids and the bitter taste is due to bases present in them. Acids turn blue litmus into red and bases turn the red litmus into the blue.

→ Acids and bases neutralize each other’s effects.

→ Acids and bases can be tested using litmus, turmeric, methyl orange, and phenolphthalein indicators.

→ On passing carbon dioxide gas through lime water, lime water turns milky.

→ On passing, excess carbon dioxide gas through lime water, its milky colour disappears due to the formation of soluble calcium bicarbonate.

→ Bases turn phenolphthalein pink in colour.

→ Acids and bases react to produce salt and water.

→ The flow of current in the solution is due to ions present in the solution.

→ In acids H+ ions are present. Acids produce hydrogen ion H⁺(aq) in a solution due to which solutions become acidic.

→ Bases produce hydroxide (OH^–) ions in water.

→ Alkali is a base that dissolves in water.

→ Bases are soapy to touch, bitter, and corrosive.

→ All acids produce H⁺(aq) and bases produce OH^–(aq) in an aqueous solution.

→ The process of the dissolving of acids or bases in water is highly exothermic, therefore to dilute them these should be added and mixed slowly in water. Never add water to concentrated acid.

→ A universal indicator is a mixture of several indicators.

→ Universal indicators show different colors for different concentrations of hydrogen ions in the solution.

→ A scale known as the pH scale has been developed for measuring the concentration of hydrogen ions present in the solution.

→ The ‘p’ in pH stands for ‘potenz’ this is a German word which means power.

→ On the pH scale, we can measure pH generally from 0 (very acidic) to 14 (very basic).

→ Higher is the concentration of hydronium ion, less is the value of pH. A neutral solution has a pH value of 7.

→ If the value of pH is less than 7 then the solution is acidic and if pH lies between 7 to 14 then the solution is basic.

→ Those acids which produce a large number of H⁺ ions are called strong acids and those acids which produce less H⁺ ions are weak acids.

→ Our body works in the range of 7.0 to 7.8.

→ When the pH value of rainwater is less than 5.6 it is called acid rain.

→ To get rid of acidity in the body, and antiacid like magnesium hydroxide which is a weak base is used.

→ If the pH value is less than 5.5 in the mouth, decay of teeth starts.

→ Nettle is a herbaceous plant that causes painful stings due to methanoic acid present in stinging hair. A traditional remedy is rubbing the area with the leaf of the dock plant.

→ Common salt (NaCl) is produced by the reaction between hydrochloric acid and sodium hydroxide.

→ Bleaching powder is produced by the action of chlorine on dry slaked lime.

→ Bleaching powder is used in the paper and textile industry for bleaching. It acts as an oxidant and as a disinfectant.

→ Baking soda (NaHCO₃) is produced from sodium chloride.

→ Sodium hydrogen carbonate is a mild non-corrosive base. It is used in the production of Baking powder and used in the preparation of cakes. It is also used in fire extinguishers.

→ Washing soda (NagCO₃.10H₂O) is prepared from sodium chloride. It is used in the glass, soap, paper industries. It is used to remove the permanent hardness of the water.

→ The chemical formula for hydrated copper sulfate is CuSO₄.5H₂O and of gypsum is CaSO₄.2H₂O.

→ Plaster of Paris is obtained from calcium sulphate hemihydrate (CaSO₄. \(\frac{1}{2}\) H₂O) by heating it at 373K.

→ Indicators: These are the substances that give different colors in acidic and basic solutions e.g. litmus, turmeric, phenolphthalein, methyl orange, etc.

→ Olfactory Indicators: There are some substances whose odour changes in acidic or basic media, which are known as olfactory indicators.

→ Acid: Those compounds which have one or more hydrogen atoms and which give hydrogen (H⁺) or hydronium (H₃O⁺) ions (H₃O⁺) ion in an aqueous solution are called acids. These are sour in taste.

→ Ionization: It is a process in which a substance produces ions in water, ionization.

→ Basicity of an acid: Basicity of an acid is the number of hydronium ions [H⁺] produced when one molecule of acid gets completely ionized in an aqueous solution.

→ Base: Bases are those compounds which are metal oxides or metal hydroxide or aqueous ammonia and these react with hydronium ion (H₃O⁺) of acids to produce salt and water.

→ Neutralization: Due to the reaction between acids and bases, salt and water are produced. This is called a neutralization reaction.

→ Alkali: Those basic hydroxides which on dissolving in water form hydroxyl (OH^–) ions, are called alkali.

→ Universal indicator: It is a mixture of various organic substances which show different colours with solutions having different pH values.

→ Dissociation: When a molecule or ionic compound dissociates into two or more atoms or ions, this is called dissociation.

→ Chemical dissociation: A reaction in which a molecule of a compound breaks into atoms or ions is called chemical dissociation.

→ The water of Crystallisation: Water, which is present in crystals of a substance is called water of crystallization. e.g., FeSO₄.7H₂O, Al₂O₃.2H₂O, CuSO₄.5H₂O, Na₂CO₃.10H₂O.

→ Efflorescence: The process of release of crystalline water from hydrated salts into the air is called efflorescence.

→ Deliquescence: This is a process in which a substance absorbs moisture from the atmosphere and dissolves in the absorbed water to form a solution.

→ Dilution: On mixing acid or base in water, the concentration of ions (H₃O⁺/OH^–) per unit volume becomes less. This is called dilution.

→ Chlor-alkali process: The electrolysis of sodium chloride solution is called chlor-alkali process.

→ According to the law of conservation of mass matter (or Mass) can neither be created nor destroyed in a chemical reaction.

→ If the number of atoms of each element is the same on both sides of the arrow in a chemical reaction then the chemical equation is a balanced equation.

→ The method used to balance chemical equations is known as the Hit-and-Trial method since we make trials to balance the equation by using the smallest whole number coefficient.

→ The solid, gas, liquid, and aqueous states of reactants and products are represented by the notations: (s), (g), (l), and (aq) respectively.

→ When reactants and products are present as solutions in water then the word aqueous (aq) is written.

This PSEB 11th Class Sociology Notes Chapter 12 Western Sociological Thinkers will help you in revision during exams.

PSEB 11th Class Sociology Notes Chapter 12 Western Sociological Thinkers

→ During the 19th and 20th centuries, many changes came in the European society and it is said that Sociology originated to study such changes.

→ From the 17th-19th centuries, many philosophers wrote new books which gave a great contribution to the emergence of sociology. Montesquieu and Rousseau are quite important among them.

→ Auguste Comte was a French philosopher and is considered as the Father of Sociology.

→ He wrote a book ‘The Course on Positive Philosophy’ in which in 1839, he used the word ‘Sociology’. He called it a science of society.

→ Comte gave the theory of Positivism and said that social phenomenon can also be understood with scientific explanation and positivism is that method.

→ So, positivism is the systematic method of observation, experience, comparison, and historical method with which society can be scientifically studied.

→ Comte studied different societies and said that to reach the present stage, society had to cross through three stages and these stages are the Theological stage, Metaphysical stage, and Positivistic stage. This is Comte’s law of three stages.

→ Karl Marx was a German Philosopher who is known for his views given on class and class struggle.

→ The concepts of communism and socialism were also given by Karl Marx.

→ Marx was of the view that the history of society, is the history of class struggle.

→ There exist two classes in all the societies-capitalist class which owns all the means of production and labour class which is not having anything to sell except its labour.

→ There is the existence of conflict between the both to get more and this is known as class struggle.

→ Emile Durkheim is also known as one of the founding fathers of sociology.

→ He tried to establish sociology as a science. He was the first professor in the subject of sociology.

→ Durkheim gave a great contribution to the subject of sociology and some of the important concepts given by him are the concept of Social Fact, Theory of Suicide, the theory of Division of Labour, the Concept of Religion, etc.

→ Durkheim was of the view that the concept of division of labour existed in society right from ancient times.

→ The nature of society is determined due to the division of labour.

→ Max Weber is one of the important sociologists and founding fathers of sociology.

→ Like Marx, he was also a German Philosopher.

→ He gave many concepts to sociology such as the concept of social action, Verstehen, Protestant Ethics and Spirit of Capitalism, Authority and its types, Bureaucracy, etc.

→ Class: Group of people whose means of production are common.

→ Authority: It is a form of power supported by the norms of a social system and accepted as legitimate by those who participate in it.

→ Social Action: It is an act that cares about the actions and reactions of individuals. If the acting individual takes account of others’ behaviour, it is social.

→ Class Consciousness: The awareness among members of a class about their common motives.

→ Class Struggle: There exists a conflict of interests between capitalist and labour classes. This conflict of interests becomes a reason for class struggle. When class consciousness increases among the people, class struggle also increases.

→ Positivism: In positivism, it is considered that society acts according to certain rules which can be discovered.

→ Mechanical Solidarity: The sense of unity among the members of a homogeneous society is called mechanical solidarity.

→ Organic Solidarity: In many societies, people have differences among them and that’s why they depend upon each other. The unity which exists in such a society is known as organic solidarity.

This PSEB 11th Class Sociology Notes Chapter 11 Social Change will help you in revision during exams.

PSEB 11th Class Sociology Notes Chapter 11 Social Change

→ Change is the law of nature. There is nothing in this world that has not yet changed. Even nature changes itself from time to time.

→ When change comes in different parts of society and the change affects the structural change comes in the ways of living of the people.

→ There are many features of social change such as it is a universal process, speed of changes is different in different societies, it is community change, no prediction regarding change is possible, it is the result of many interactions, it can be planned as well as unplanned, etc.

→ There are many types of social change such as evolution, development, progress, and revolution.

→ Many a time these words are used for each other but in Sociology, they are very much different from each other.

→ The meaning of evolution is equal change internally. This is a very slow process and social institutions change from simple to complex.

→ Development is also an aspect of social change.

→ When change comes in anything in the desired direction, it is known sis development.

→ Different sociologists have given different bases of development.

→ Progress is another type of social change. It means to move towards achieving objectives.

→ Progress is the efforts made to achieve objectives which is definite and which get scope ration from social values.

→ Revolution brings a sudden and fast change in society with which old structure comes to an end and new structure comes forward.

→ Many a time people become so dissatisfied that they stand up against the system. It is known as revolution.

→ The revolution of 1789 A.D. in France was a change of such type.

→ Many factors influence the direction and speed of social change such as natural factors, beliefs, and values, social reforms, demographic factors, technological factors, educational factors, etc.

→ Diffusion: The process by which cultural traits spread from one culture to another.

→ Innovation: Introduction of new ideas, techniques, etc., and better use of existing ideas and technology.

→ Social Change: Change in the functions of social structure and social system.
