This article presents a program in C++ which defines a class of polynomial name in order to implement a data abstract type (TAD), a polynomial through a class that performs polynomials arithmetic with operations such as addition, the product of a constant by a polynomial, the product of a monomial by a polynomial and a polynomial derived. The program code is presented, and its details, features and limitations are discussed. Implementation is done in the Dev C++ 4.1 compilator; a GNU compilator with GPL licence.

Considering a discussion, under the prism of the Phenomenology of Perception developed by Maurice Merleau-Ponty (1908-1961), it is possible to observe that Mathematics Education has shown interest in the postulates of this philosopher through the research being carried out in the Brazilian territory. In order to identify the research approach, based on Merleau-Ponty's postulates and in the area of Mathematics Education, we elaborated a study that allows us to visualize the research scenario of the last five years regarding the use of this philosopher as a theoretical reference. The research has a qualitative approach and the data production is carried out through a documentary analysis. The results showed the existence of three research axes: the student, the teacher and teaching, being the teacher the research axis with more evidence in the works considered so far.

The study presented aims to promote and understand the agent commitment of students, future educators, in initial education through an expanded educational experience in order to proactively rethink their professional role. Participated 41 students from the Faculty and the Bachelor of Initial Education, who were studying the third year of the career at the National University of Río Cuarto, Argentina. Under an interpretive qualitative design, an expansive educational experience was designed so that students could proactively rethink their professional role from their agencies, based on an activity that proposed going to the territory, specifically, walking the city, in search of art to teach. Data were collected in three moments, during the investigation almost finished and already concluded. The results show that students develop proactive actions and emotions that motivate rethinking ...

The purpose of the research was to demonstrate how the application of the Inverted Class pedagogical model (Flipped Classroom) improves learning in English grammar proficiency in students of the Working Adult program, UPN, Lima-2018. The type of research was applied, scientific method and quasi-experimental method of explanatory level. The design was quasi-experimental with two equivalent groups and quantitative approach measurement. The sample consisted of 40 students of the program. The data collection technique was the evaluation for both groups a pretest and posttest test with their checklist instrument. A survey was applied to the students of the experimental group, observation sheet of learning sessions. The hypothesis was tested using the Student's T statistic for independent samples, using the SPSS version 24 program, with 5% margin of error, with P-value = 0 less than 0.05 signi...

El objetivo del presente trabajo fue, construir y validar un sistema observacional para realizar análisis de interacciones didácticas en dos clases de ciencias en el bachillerato, y describir de manera exploratoria, las relaciones establecidas entre el desempeño del profesor y el desempeño del estudiante. Este estudio se llevó a cabo en tres fases: En la fase 1 se delimitaron las categorías apegadas a un enfoque teórico. En la fase 2, en el software Lynx versión 4.1 se programaron las categorías e indicadores. y se calculó el índice de acuerdo entre observadores. En la fase 3 se probó el sistema de observación, analizando dos vídeo grabaciones de clases de ciencia. De acuerdo con los resultados, este sistema de registro observacional obtuvo buen índice de confiabilidad, mostrando ser útil para analizar las interacciones didácticas. Los datos también mostraron, que los c...

The objective was to determine the correlation between gamification and motivation. It was developed through quantitative, non-experimental and correlational research. We worked with a census population of 253 students of regular basic education. To obtain data, the Gamification Observation Guide by García (2020) and the MSLQ Motivation Questionnaire by T. García et al. (1988). The results indicated that there is a very low, significant relationship of 0.025 (p value = 0.0694> 0.05). It is concluded that gamification is not related to the motivation of the students, most of the teachers, in the development of their classes, do not use digital tools - a necessary element in the delivery of classes at a distance and virtually due to the difficult situation caused by COVID-19. Likewise, teachers suffer from inexperience in handling social networks, videoconferences and online forms.

The aim of the study was to determine the growth direction, position and size of the maxilla and mandiblewith skeletal open bite Class II and III. Methodology: This is an observational, descriptive andcross-sectional investigation. The population consisted of 100 lateral cephalometric radiographs of patientswith clinical diagnosis of skeletal open bite. The sample was not probabilistic for convenience. TheNemoceph program was used for Ricketts analysis to get the values of variables. The sample consistedof 36 radiographs of skeletal open bites. The data obtained were analyzed with the chi-square test at aconfidence level of 95% equivalent to 1.96 and a margin of error of 5%. Results: Of the 36 open bites,72.2% were class II and 27.8% Class III skeletal pattern. The two groups showed mostly normodivergentgrowth direction in the maxilla but all the mandibles showed hyperdivergent growth. I...
