El problema que se detectó en la Escuela de Post Grado de la UNHEVAL es la existencia de la asignatura de estadística con diferentes nomenclaturas según las menciones, tanto en las maestrías, como en los doctorados, en este sentido, se ha observado que los egresados tienen dificultades para procesar los datos recolectados durante el trabajo de campo, en este sentido se propone que la asignatura de estadística tenga un solo nombre y con la misma sumilla única, para todas las maestrías y doctorados, todo ello implica que la asignatura esté a cargo de docentes con especialidad en la Ciencia Estadística. Para ello, el informe final se diseña de la siguiente manera: Capítulo I, todo lo referente al problema de investigación. Capítulo II, se incluye el marco teórico, básicamente considerando: los antecedentes de la investigación, las teorías básicas y la definición conceptua...

El problema que se detectó en la Especialidad de Matemática y Física de la UNHEVAL es que los alumnos con mucha dificultad podían determinar el dominio y rango de las funciones de manera analítica; ello constituye un problema de magnitud, porque serán docentes de matemática y física; o sea, docentes sin capacidades específicas ejerciendo la docencia para estudiantes de Educación Básica en plena formación, en la cultura matemática; por tanto, es probable que esto sea uno de las factores de la deficiencia en el aprendizaje de los alumnos de educación básica.Debido a lo dicho y tratando de paliar en algo el problema de aprendizaje del dominio y rango de funciones, en la investigación, se propone la aplicación del método gráfico con la ayuda del programa Geogebra, entonces en función a ello, el informe final ha sido diseñado de la siguiente manera:Capítulo I, incluye to...

The purpose of the study was to test the effectiveness of the application of the first and second derivatives to analyze the mathematical functions in future teachers of Mathematics and Physics at UNHEVAL; for this, a cause-effect study and quasi-experimental design was carried out, hoping to optimize the learning of functions in a graphical and analytical way, by means of the exact location of the maximum and minimum points, inflection, determination of the concavity up and down, and others; we worked with a sample of 114 students, of them 73 units of analysis were control and 41 experimental; the data were collected with the written evaluative test, and they were processed obtaining descriptive statistics that allowed to say that the value Z = 7,09 is higher with respect to the critical z = 1,96 at 95% reliability, which allowed to reject the null hypothesis and accept the research hyp...

The problem that has been detected in the Specialty of Mathematics and Physics at UNHEVAL is that students determine the domain and range of functions analytically with much difficulty; this is indeed a very worrisome problem since they will be teaching Math and Physics without enough skills at basic levels where students are in formation and discovering the foundations of Maths; which is likely to be one of the reasons of many deficien- cies in students at basic leves.Because of what has been said and to try to decrease the problem of learning domain and range of functions, in this research it is been proposed the application of the graphical method with the Geogebra software; hence the final report has been designed as follows: Chapter I includes everything related to the research question as: description of the problem,formulation of the research problem, objectives, hypothesis, justi...

Huanuco is located in the center of Peru. In its surroundings it is bathed by three basins such as the Marañón, Huallaga and Pachitea, which in turn receive the tribute of their waters from a set of micro-basins, such as the Nupe, Murmunya, Lauricocha, Carhuacocha, Vizcarra, Higueras, Huacar, the Eco , Llata, Quera, among others. The purpose of the research was to detect the factors of the contamination process of the basins and micro-basins of Huánuco, to test the inventory of the main micro-basins of Huánuco in the quality of life of its inhabitants and to determine the role of environmental education in the preservation of basins and micro-basins. The main method was observation, on-site view of the problem, information gathering, consultation of bibliographic sources and their analysis. The result was a high degree of contamination of the micro-watersheds, little preservation pol...

The objective of this article is to analyze and measure the environmental impact from the photovoltaic energy use through three photovoltaic systems that already exist in Peru. To reach that an energy balance or energy payback time (EPBT) calculation and a carbon footprint sizing was made. For the analysis, the stage of manufacture, transport, installation and uninstallation of solar panels was considered, furthermore, the manufacture of the elements from the Balance of System (BOS) that contribute significantly to the life cycle of the solar panels.  The first case is a group of 5 rural houses at Puno that consume 10 kWh/day. The second case is the photovoltaic system that is installed at the Institute of Mining Engineers of Peru roof and has a 20 kWp capacity. The third case is the Rubi Solar Central at Moquegua, which has a 179.5 MWp capacity. The EPBT obtain for the three cases ...

The objective of the study was to evaluate the incidence of the application of trigonometric functions in a heuristic mode, on the cognitive development of adolescents from Cauri. In this sense, the autonomous variable was applied to the dependent variable to generate an effect of improvement in cognitive development. The study had an explanatory level, basic type and quasi-experimental design. The population was made up of 335 young people from Cauri, from which a non-random sample of 46 was selected, who were grouped as follows: 20 in the experimental group and 26 in the control group. The data were collected through three evaluative written tests, each with 10 propositions to develop. The data obtained were processed in Microsoft Excel, which allowed the calculation of the statistics corresponding to the descriptive and inferential analysis. The results showed that the test T value is...
