I have just looked through copies of 10 current high school geometries and in not one of them can I find a direct and explicit proof of the fact that if the square on one side of a triangle equals the sum of the squares on the other 2 sides, it is a right triangle. In some books it is proved indirectly by proving its converse and its opposite, but no attention is called to the fact. Some authors use the fact in problems without having proved it or mentioned it and these same authors seem worried in their opening chapters if the converse of any little proposition is assumed to be true without giving the proof of it.

The oral form-discrimination abilities of 18 orally educated and oriented deaf high school subjects were determined and compared to those of manually educated and oriented deaf subjects and normal-hearing subjects. The similarities and differences among the responses of the three groups were discussed and then compared to responses elicited from subjects with functional disorders of articulation. In general, the discrimination scores separated the manual deaf from the other two groups, particularly when differences in form shapes were involved in the test. The implications of the results for theories relating orosensory-discrimination abilities are discussed. It is postulated that, while a failure in oroperceptual functioning may lead to disorders of articulation, a failure to use the oral mechanism for speech activities, even in persons with normal orosensory capabilities, may result in poor performance on oroperceptual tasks.

Discipline in class is essential. Without it the educational processes and teachings are difficult. In this manner curricula goals are almost impossible to achieve. There are and there always will be some kind of conflicts between teachers and students, but they should not evolve to become a problem. Teachers (especially elderly teachers) often express pessimism of contemporary students. They say that today's students have less knowledge, they do misbehave more often than previous generations. A study among students was conducted. It was trying to determine the rate of discipline in schools in Celje to see if these statements are true. The questionnaire to students of one primary and one high school in Celje, Slovenia were distributed. The answers from 234 students were received. On the one hand, it was found out that senior high school students have the worst level of discipline of all the grades tested. They themselves assess their class atmosphere as less disciplined. They report that teachers use a lot of time to calm the class down. All this is probably a factor in lower average grade that the senior high school students have. On the other hand, it was found out that teachers do not react to the disturbance or they are trying to be repressive. These are not the correct ways of dealing with discipline issues. Therefore, there are some recommended ways how teachers should react. Keywords: discipline in class, primary school, contemporary student, elderly teachers.

Objective: To review the rules, resolutions and existing documents relating to consultant and advisor to better target the actions of those who exercise these roles. Methods: The following documents were consulted: Statute of CAPES, through Decree No. 7692 of March 2, 2012; Ordinance No. 47 of 17/10/1995; Opinion 977 1965 Newton Sucupira; Area Document of Medicine III; Interministerial Ordinance 251 of 2012, based on Decree No. 7642 of 2011 of the Ministry of Science and Technology; CAPES Regiment. Results: The Brazilian Postgraduate system is divided in two different fields, according to its aspects: the "lato sensu" postgraduate, defined as all professional studies performed after the high school graduation; and the "stricto sensu" postgraduate that includes the master degree and the doctorate, both of them different from what is known as MSc or MS and PhD. The Brazilian doctorate is recognized as academic because its purposes include to improve the scientific and the teaching levels of university docents. The master degree has two different objectives one is to be academic and similar to the doctorate; the other is to upgrade professionals to a higher level than specialist or MBA and is denominated professional master degree. The master degrees and the doctorate are designated as courses and may be put together in a structure known as stricto sensu postgraduate program. The complexity of these courses and programs in all the areas of the superior human knowledge requires a large number of professional directly involved with this system and other professionals that attend them, called consultants and advisors. The consultants are counselors, and the advisors are assistants, both of them legally established with the incumbency to aid the postgraduate staff in all their duties. Conclusion: Nothing prevents a person from being a consultant on the situation and advisor on another, even in the same institution. Have knowledge about what being a consultant and advisor is required to exercise the function within the limits and dimension that the wingspan of the professional allows.

While personalized learning environments often include systems that automatically adapt to inferred learner needs, other forms of personalized learning exist. One form involves the use of personal analytics in which the learner obtains and analyzes data about himself/herself. More known in informatics communities, there is potential for use of personal analytics for design of instruction. This chapter provides two cases of personal analytics learning explorations to demonstrate their range and potential. One case is of a high school student examining how sleep influences her mood. The other case is of a sixth-grade class of students examining how deviations from typical walking behavior change distributional shape in plotted step data. Both cases show how social support and direct experience with data correction are intimately involved in how youth can learn through personal analytics activities.

The Covid-19 pandemic has caused several changes in the human state of mind, in particular adapting to the culture of the new normal while lockdown measures are implemented. This study explored the effect of the lockdown measure on the level of anxiety of high school students, comparing those identified as introverts and extroverts. Participants (N = 103) filled out the given survey, which determined that they were both introverts or extroverts and the level of anxiety that they had before, during, and after the lockdown caused by the pandemic. According to statistical analysis, the result showed that the level of anxiety perceived by those feeling the sense of extroversion was statistically higher than those with introversion, at the significance level of 95%. In addition, the analysis revealed that there was no correlation between extroverts and anxiety before, during, and after the lockdown measures. On the other hand, there were statistical correlations between the level of introversion and the level of anxiety in every stage of lockdown: before, during and after, indicating that the lockdowns due to the global pandemic did not affect extroverted people anxiety as much as it affected introverts. Moreover, it also showed that the level of anxiety of the introverts has become even more intensified even after the lockdown.

How do people feel emotions for someone else? This has been studied asempathy—feeling the same emotion that someone else feels. But people also feel emotions for someone else that the other person doesn’t feel, such as feeling angry for someone who is sad. We use appraisal theories to predict that people feel an emotion for someone else when they appraise that person’s situation differently. According to appraisal theories, people react to misfortunes with anger if they are caused by another person, but not if the cause is impersonal, and we predicted that this would also be true in feeling emotions for another person, regardless of what the other person feels. In two studies, subjects learned about a disadvantaged high school student who applied to college and was rejected from every school. Subjects felt angrier when they learned that the student’s friend caused the bad outcome than when the student made a well-intentioned mistake, but they did not think the student felt angry. The difference in subjects’ anger was mediated by changes in appraisals of agency. The student believed the rejections were caused by bad circumstances and felt sad in both conditions. The results extend research on empathy and other vicarious emotional experiences by supporting appraisal as a process that is involved in feeling emotions for other people.
