KNOWLEDGE ABOUT THE CHANGES IN PUBERTY AMONG PREPUBESCENT CHILDREN IN SELECTED COUNTRIES

Puberty is an important element of sex education in the global dimension. The pre-pubescent needs to be adequately prepared in time for puberty, for all changes, relationships and contexts. The cognitive and informative level of puberty knowledge represents the level of learning and expresses the amount and quality of information or knowledge. Our pedagogical research realized the level of knowledge about changes in puberty shown by primary school pupils the Czech Republic, Sweden, China, Spain. We used the didactic knowledge test to determine knowledge about changes in puberty among primary school pupils. The level of knowledge about changes in puberty was verified by selected test tasks. We used descriptive statistics to describe the data. The non-parametric Kruskal-Wallis test was used to identify statistically significant differences in pupil responses across countries. The results pointed out that the pre-pubescent people did not have the right knowledge and did not comprehend the relationships and connections with the issue of puberty comprehensively. The prepubescent often do not realize the biological aspect and its importance for the future reproductive life of each person in the context of further changes. Puberty can be described as a fundamental hormonal process of physical changes. Early adolescence preparedness means that children should acquire the necessary knowledge about it before it starts, even when they are primary school pupils. Educational research conducted by us investigated the level of knowledge about changes in puberty shown by primary school pupils in selected countries. Results (Q8): The answers also suggest the respondents’ awareness of other changes than biological. Most of the responses were in the category of partially correct answer. The respondents indicated only various incomplete combinations of other changes. The most frequent responses included the need to spend leisure time with peers, aspects associated with emotional instability, love and affection, and the need to participate in decision making on matters that relate to them. In this question, the least knowledge was shown by the respondents from the Czech Republic.


Introduction
The present research focuses on the identification of the cognitive and informative level of knowledge about puberty among primary school pupils (by means of testing) and information about mutual communication about puberty among primary school pupils, their teachers, and families (by means of a survey among pupils). The key concepts of the present research are puberty and knowledge about puberty among primary school pupils. The paper focuses on the level of knowledge about the changes in puberty, as reported by primary school pupils in selected countries. Miluše Rašková, Ph.D.). Given the situation with the spreading of COVID-19 coronavirus in Europe and closure of schools in spring this year, so far the authors have been unable to statistically evaluate the data in the context of other countries because data collection in elementary schools in Croatia was conducted at a later date. For this reason, the comprehensive results from Croatia are not included in the paper as they are currently being processed.

Problem Statement
The focus of the research problem is on identifying the level of knowledge about puberty among primary school children before its onset. Prepubescent children need to be prepared for puberty in time and in an appropriate manner; this should include all related associations and contexts. Timely readiness for puberty means that children have the required knowledge before its onset when they are in primary school. Knowledge is gained in the process of learning and represents the level of awareness. The cognitive and informative level of knowledge about puberty includes the amount and quality of relevant information.
Most information is of a general nature and forms an integral part of general knowledge. The system of acquired knowledge and skills is a part of education and forms a holistic human personality.
The personality of an educated person should match the culture of the era. Education also includes the adoption of values and the development of the attitude towards the world, society, and oneself. The attitudes are reflected in the ability of critical thinking and in the opinions and behaviour in practical life.

Research Questions
In relation to the research problem, the researchers focused on the area that represents the level of knowledge about the changes in puberty among pubescent children. The part of the educational research study performed by the researchers focused on the level of knowledge about the changes in puberty among primary school children in selected countries (Czech Republic, Sweden, China, Spain, and newly Croatia-see introduction).

Purpose of the Study
The purpose of the study was to show whether prepubescent children were sufficiently educated in the area of the changes in puberty. The researchers also focused on whether prepubescent children understood puberty comprehensively with respect to all changes in the biological, psychological, and social areas, taking into account the specificity of both genders.
In the life of every person, puberty is an important part of human development. During puberty, the signals that concern the hοrmοnal changes that are required are sent from the brain to the reprοductive οrgans, which stimulate growth, develοpment of functiοns, and other changes in the brain and οther organs. Along with the hormonal process of physical changes in both genders, during which the reproductive organs mature and start to prοduce sex hοrmones (sperms or ova), changes are taking place in the physical structure. During that period, growth is decelerated or even stopped, while changes in the physical structure and the appearance of secondary sex characteristics, including pubic hair in the armpit, skin changes, and acne development also take place. Changes in boys further include body thickening and muscle growth, pubic hair on the scrοtum, hair οn the face, and vοice change. Changes in girls include hair in the pubic area, gaining female shape οf the bοdy, and breast growth.
The period of puberty is marked also by significant psychological changes including becoming aware of others' personality. Puberty is a period of searching for and building one's identity. The manifestations of psychological changes in puberty include refusal of a subordinate role that changes the individual's social role and causes attacks against authorities including the parents and teachers. Changes take place in the attitude towards the school and the teachers as well, which are no longer considered a formal authority, unless there is something to be impressed by. Generally, adolescent children want to participate in decision making about matters related to them and they start to critically assess their parents and other adults. Leisure time is a significant aspect in the life of an adolescent. They want to spend time with their friends. For some individuals, puberty may become an impulse for artistic expression, reading complex literary works, doing attractive sports, interest in mysteriousness, romance, nature, and other activities. Pubescents tend to be emotionally instable. There are changes in their self-evaluation, they tend to be touchy and vulnerable. According to psychologists, the reason behind this emotional instability is primarily the hormonal changes. Secondarily, instability may be supported by psychological changes and changes in interpersonal relationships. In puberty, there are also changes in the way of thinking. During that period, individuals start to think hypothetically (at the level of formal logical operations), a process that affects not only their οverall attitude tο the world but alsο tο themselves.

Research Methods
The data collection was performed by means of non-standardized knowledge achievement tests

Findings
The research sample included a total of 349 prepubescent children from the Czech Republic, China, Spain, and Sweden aged 10 to 12 years. The comparison of the overall results using the Kruskal-Wallis test showed that the overall score achieved by the boys and girls in the test significantly differed in the countries involved (p<0.0001, see Table 1 below). Significant differences were also observed in the comparison of the overall point score of the responses between all countries (p<0.05-significant differences between the results of the boys and girls from the countries involved). The following text describes the overall results concerning the level of knowledge about the changes in puberty in the countries involved with a focus on physical changes in boys (Q6) ( Figure 01) and girls (Q7) (Figure 02) and other changes that puberty induces in both genders (Q8) (Figure 03).

In this question, the least knowledge was shown by the respondents from the Czech Republic.

Conclusion
The incomplete or missing knowledge about puberty suggests that prepubescent children do not consider the issue of puberty and relevant associations and contexts in a comprehensive way. Younger school-aged prepubescent children are often unaware of the biological aspect and its importance for future reproductive life of each person in context with other changes. Prepubescent children usually associate puberty only with psychosocial changes.
These findings suggest that teachers should strengthen the knowledge of prepubescent children about puberty in a comprehensive manner including all changes in the biological, psychological, and social areas, taking into account the specificity of each gender.
The results concerning the level of knowledge about puberty among boys and girls in the countries involved (Q1-Q9) have been continuously published (Rašková & Otavová, 2019;Rašková & Provázková Stolinská, 2015a, 2015b, 2017Rašková & Vavrdová, 2019;Rašková et al., 2015 etc.). The aim of paper was to emphasise the insufficient or missing knowledge concerning the changes in puberty among prepubescent children across the countries involved.
The testing of the knowledge among prepubescent children in selected countries revealed their incomplete knowledge. It was observed that the respondents' knowledge was not completely absent, but rather that they did not understand puberty comprehensively. It was observed that they did not associate the achievement of the reproduction ability, full sexual maturity, and the completion of physical growth with psychological and social changes.
In the area of physical changes during puberty in both genders, the respondents reported in their answers various incomplete combinations of changes. Although the respondents were aware of other than biological changes, in their responses they indicated only various incomplete combinations of other changes (most frequent responses included the need to spend leisure time with peers, aspects associated with emotional instability, love and affection, and the need to participate in decision making on matters that relate to them).
These findings are especially important to teachers, who should focus their work on strengthening the development of comprehensive knowledge about puberty. Education should also include the knowledge about the changes in puberty. From an educational perspective, the complete knowledge about puberty is part of overall personality development.
