ResumenPresentamos un esbozo del problema de investigación que forma parte de un trabajo de tesis. Tras analizar el currículo español de matemáticas y algunos manuales escolares, hemos encontrado una ausencia de las cuestiones a las que responden los conocimientos geométricos propuestos para la Educación Secundaria Obligatoria (alumnos de 12 a 16 años). Después de haber revisado diferentes estudios relacionados con la enseñanza de la geometría, postulamos que los problemas espaciales pueden ayudar a encontrar una posible razón de ser de esos conocimientos geométricos. Así, pretendemos identificar y abordar algunos problemas espaciales a fin de confirmar dicha hipótesis.Palabras-clave: Teoría Antropológica de lo Didáctico, Geometría elemental, Conocimientos geométricos, Problemas espaciales, Modelización Espacio-Geométrica.Abstract.We present an outline of the research problem that is part of a doctoral thesis. After analysing the Spanish mathematics curriculum and some textbooks, we have found an absence of the questions to which the geometric knowledge proposed for high school (students aged 12 to 16 years) answer. After reviewing different studies related to the teaching of geometry, we postulate that spatial problems can help to find a possible justification for such geometric knowledge. Thus, we intend to identify and address some spatial problems in order to confirm this hypothesis.Keywords: Anthropological Theory of Didactics, Elementary Geometry, Geometric Knowledge, Spatial Problems, Space-Geometric Modeling.

The research problem relates to the examination of the relationof socio-demographic characteristics (gender, level of education and the place where most of childhood was spent) and the self-esteem of the respondents with loneliness.In investigating this problem, the focus was primarily on the perception of the distribution of loneliness, and the examination of the relation of independent variables (socio-demographic characteristics and self-esteem) with the dependent variable (loneliness).The sample of respondents consists of 677 high school students (49.34%) and college students (50.66%) of Bosnia and Herzegovina. The range of years of subjects ranges from 15 to 23 (AS = 18.696).The results of the study show that there is a statistically significant difference in loneliness with regard to gender (U = 38672.000, Z = -6.122, p = .000), to the level of education (U = 42292.500, Z = -5.905, p = .000) and the place in which the respondents spent most of their childhood (χ2 = 9.383, df = 2, sig = .009). The results show that there is a statistically significant relation between self-esteem and loneliness (ro = -.401, sig = .000, N = 676).

Graphing calculators are revolutionizing the learning and teaching of mathematics. Students can view and manipulate graphs of functions in a matter of seconds. Such features as “plot,” “graph,” “trace,” and “zoom” offer opportunities for users to develop an understanding of the terms variable and function. According to the Curriculum and Evaluation Standards for School Mathematics (NCTM 1989), these concepts are vital aspects of the middle school curriculum. According to the standards document, “[A]n ideal 5-8 mathematics curriculum would expand students' knowledge of numbers,… patterns and functions, and the fundamental concepts of algebra” (pp. 65-66). In addition, “[T]echnology, including calculators, computers, and videos, should be used when appropriate” (p. 67). It stand to reason that tools to aid in understanding such concepts as variable and function, specifically graphing calculators, should not be reserved for high school juniors and seniors. This article discusses the use of graphing calculators by students of middle school age in an enrichment program for academically able, but economically disadvantaged, students. The exercises described helped students develop an understanding about variable and function. Students were actively engaged in problem solving that involved hands-on, real-life activities.

This study sought to determine the Senior High School English teachers’ teaching practices in terms of punctuality, attendance and its relationship to students’ academic performance. Specifically, it determined the Senior High School English Teachers’ level of punctuality and attendance; the Senior High School Students’ level of academic performance in English; and the significant relationships of the teachers’ level of punctuality and attendance and their Senior High students’ level of performance in English. The study used the descriptive-correlational survey method. The respondents of the study were the twenty four (24) teachers of the twelve (12) senior high schools of Maguindanao, Philippines. There were two (2) Senior High English teachers that were chosen randomly from each senior high schools of Maguindanao. It has a total of twenty-four (24) Senior High English Teachers. In every teacher, there are 10 senior high school students chosen randomly with a total of two hundred forty (240) senior high school students. The immediate supervisors of the teachers from the twelve (12) secondary schools answered the research problem number 1, while the final grades in English of the two hundred forty (240) senior high students were taken from their English teachers to answer the research problem number 2. The respondents of this study were chosen randomly using lottery. Pearson’s Product - Moment Correlation Coefficient was used to determine the significant relationship of the level of punctuality and attendance of the English teachers to the students’ level of academic performance. Based on the findings of the study, it is concluded that the Senior High School English Teachers’ level of teaching practices is influenced by their punctuality and attendance. It further concluded that teachers’ punctuality and attendance contributed to students’ level of academic performance in English.   Keywords: Senior High School English Teachers, Punctuality, Attendance, Students’ Academic Performance

This paper describes an investigation which was carried out to determine if mobile learning can be used to help high school students improve their performance in mathematics. The investigation was driven by the need to develop innovative learning solutions to eradicate the problem of low pass rates in mathematics in the Caribbean. A mobile learning application called MobileMath was developed targeting a subset of the mathematics curriculum. MobileMath offers the learner different learning strategies, game-based learning, and personalization. Two of the evaluation studies conducted are described in this paper. The first study focused on students using mobile learning on their own, while the second study explored the effects of teacher support while using mobile learning. A t-test analysis shows that there was a significant improvement in performance by students in both evaluation studies. The paper also compares the students’ performance with actual usage of the mobile learning application.

The article is devoted to the analysis of the AUE phenomenon (Convict's Codex is Unified) using a Siberian Federal District case study. The author bases the analysis primarily on neo-institutional and post-structuralist approaches.  The paper considers non-formal aspects of the AUE institution functioning related to the relationships between the nodes forming various forms and models of network interactions. The purpose of the study is the need for scientific analysis and interpretation as well as the importance to design ways to prevent and detect this phenomenon. The research problem is the contradiction between today’s approaches towards interpretation of the AUE phenomenon and inability to create effective youth policies to prevent it. The study is founded on empirical material gathered by the author in Siberian Federal District in cooperation with the “Siberian Politics” Foundation in 2017 - early 2018. The empirical part includes 9 focus groups, a survey of high school students (920 respondents), a focused interview and an expert survey. The author argues that the AUE structure includes three partly overlapping phenomena: criminal youth subculture, rhizomatous youth movement, and criminal youth organization. However, the author proves that the AUE phenomenon cannot be fully identified with any of them.

In the English teaching and learning process, there are four skills that are identified as very important; listening, speaking, reading and writing. The Indonesian government places English as a compulsory subject for junior and senior high school. But in practice, teaching English is not too maximal. Reading skills in this case reading English texts is very important because by reading it is open the opportunity to absorb other existing knowledge. Reading comprehension is an advanced level of reading skills. Senior high school students are expected to have mastered the comprehension skills of reading English texts at an advanced level. This is because most likely at the level of lectures these students are required to read English reference books. Therefore, research that reveals the problems that exist in the teaching and learning process of Reading Comprehension English texts needs to be done. Data sources were the articles about teaching English, focusing in the problem of reading comprehension. Data were words and sentences from the articles. The analysis technique used was thematic analysis. Based on the research, problem face by student in reading comprehension of English text was majoring in three theme; 1. Problems from the student self, 2. Problems from the teacher, and 3.External problems. Problems from the student self consist of three part; student basic English ability, less attraction on the subject and not motivated. Problems from the teacher were not using any method while teaching and used inappropriate method. External problems were material and environment.

The personal data of the Jaya Krama Beringin Private High School students is required in the administrative data collection by the school. Personal data includes student identification such as student name, family identification number (NIK), gender, address, mobile number, e-mail, and so on. In today's digital era data is everything, with the development of the internet network that is increasingly easy to access, it is necessary to know and be aware of what things are personal data and what should be done to protect personal data. The research problem is that the personal data security of Jaya Krama Beringin High School students needs attention due to the widespread occurrence of data theft by hackers to be misused, it is necessary to need computer software for data security. The first step in the RC4 algorithm stage is to carry out the KSA (Key Scheduling Algorithm) process which at this stage is the process of forming an S-Box (Array S) with a length of 256 bytes (index 0 to 255) based on the encryption key. After using the XOR operation on the ciphertext with the key, the XOR result of the binary number obtained is converted into plaintext.
