Este trabalho é um recorte do relato de uma pesquisa experimental com o uso do software Graphmática. O experimento deu-se através de uma sequência didática com estudantes do ensino médio de uma escola pública de Campo Grande, MS. A metodologia utilizada foi a dialógica e teve por objetivo analisar a contribuição do software e da dialogia para fazer emergir os raciocínios classificados por Peirce como abdutivo, indutivo e dedutivo. Os resultados indicam que essa possibilidade existe, mas requer mais tempo de convivência com os estudantes para conquistar confiança e corrigir algumas fragilidades decorrentes da pouco familiaridade deles com a tecnologia de bancada, bem como, alguns vícios de notação e comunicação verbal construídos durante a vida escolar.   Palavras-chave: Graphmatica. Abdutivo. Indutivo. Dedutivo. Educação Matemática.   Abstract This work is a cut of the report of an experimental research with the use of the software Graphmática. The experiment was carried out through a didactic sequence with high school students from a public school in Campo Grande, MS. The methodology used was the dialogic, which had as objective analyze the software's contribution and the dialogism to emerge the reasonings classified by Peirce as abductive, inductive and deductive. The results indicate that this possibility exists, but it requires more time with the students to gain confidence and to correct some weaknesses due to their lack of familiarity with bench technology, as well as some notation and verbal communication habits built during the school life.  Keywords: Graphmatica. Abductive. Inductive. Deductive. Mathematical Education.

The likelihood that learned skills will be maintained in natural performance settings may be affected by the number of opportunities to perform the skills following acquisition. To examine this hypothesis, 17 high school students with moderate to severe mental retardation were selected from three public school classrooms. Each student had learned one adaptive skill that he or she had performed at least twice per month without additional training for 5 months prior to this study (high opportunity). Each student had also learned one adaptive skill that he or she had not performed more often than once per month over the 5 months immediately preceding the study (low opportunity). Performance of both behaviors was probed under conditions as similar as possible to those experienced during training. Twelve of the 17 high opportunity skills were performed successfully while only 4 of the 17 low opportunity skills were completed. A sign test indicated these differences to be statistically significant. Implications of the results for selection of IEP goals and the inclusion of “opportunity” objectives are discussed.

The article summarises the preliminary results of a three-stage study of the influence of the socio-cultural context on the life and educational manifestations of modern high school students. Firstly, data on the Russian representatives of «Generation Z» were specified. At the second stage of the research, the manifestations of «Generation Z» representatives, regarding everyday school life were studied. At the third stage of the research, there were analysed different educational learning situations as opportunities for senior students to show the behavioural and intellectual characteristics inherent in the digital generation. The main results of the study make it possible to set new tasks in the study of the socio-cultural context of the educational situation of modern high school students.

With the amount of speeches delivered on social networks that students browse continuously, it is possible to use this mechanism as an additional support for classes. This research, using this possibility, seeks to present a didactic sequence applied to high school students from a public school, whose objective is to examine the concept of logic, present in the speeches of the two main candidates for the presidency of Brazil, in 2018 The proposal is to demonstrate to students how the concepts of logic can be identified in discourses that permeate the social environment and are part of the reality experienced by students. It is hoped that this research can contribute as a reference to an activity of theory and practice, such a relevant discussion in the school scenario.

The purpose of this work was to study the sexual characteristics of the relationship between the emotional reflection of high school students in the objects-values of school life and their awareness of the reasons for the need for schooling (motivation). Separately for groups of boys and girls, the following were revealed: 1) the structure of the emotional attitude to the values of school life by means of factor analysis of estimates using the method of the Semantic Differential; 2) the correlation of the identified factors with different explanations-motivations of the reasons for schooling (70 options). Schoolchildren of grades 9—11 (15—17 years) of two schools in Moscow were studied, only 253 pupils (132 boys and 121 girls), including 90 students at the same time (48 boys and 42 girls). As a result, it was found that boys have 3 factors of emotional attitude to learning (cognitive motivation, avoidance and affiliation), while girls have 4. In addition to three similar to boys, they have a communication factor. The interrelationships of these factors-motives with the variants of a conscious explanation of the reasons for the need for schooling were revealed, which made it possible to discover the qualitative specifics of the conceptual sphere of students of different sexes.

<p class="Abstrak"><strong>Abstract:</strong> This research aim is to know the effect of ecopedagogy model on aspect of ecological competence high school students. This study was quasi-experimental research with the Pretest-Posttest Nonequivalent Control Group. The research subjects consisted of two classes namely XI IIS II as the experimental class and XI IIS I as the control class. This study was conducted at MAN 1 Sintang. The data analysis used independent sample t-test which showed that the ecopedagogy model had an effect on ecological competence students. From the results of the posttest, it can be seen that the experimental class has higher value rather than the control class.</p><strong>Abstrak:</strong> Penelitian ini bertujuan untuk mengetahui pengaruh model <em>ecopedagogy</em> terhadap aspek kompetensi ekologis siswa SMA.
