En esta investigación se implementó la ingeniería
didáctica como metodología de investigación la cual
fue presentada por Artigue y Douady en Colombia en
el segundo simposio internacional en educación
matemática. Este trabajo pretendía abordar el diseño
y la evaluación de intervenciones educativas basados
en la investigación para mejorar la enseñanza y el
aprendizaje del cálculo. Se diseñaron secuencias
didácticas apoyadas en las teorías de las situaciones
didácticas y de las representaciones semióticas que
pretendían la correcta apropiación del concepto de
función en un grupo de estudiantes de Licenciatura en
Matemáticas. Los resultados evidenciaron beneficios
en el proceso de apropiación conceptual.; In this research, didactic engineering was
implemented as a research methodology which was
presented by Artigue and Douady in Colombia at the
second international symposium in mathematics
education. This paper aimed to address the design
and evaluation of educational interventions based on
research to improve the teaching and learning of
calculus. Didactic sequences were designed based on
the theories of didactic situations and semiotic
representations that sought the correct appropriation
of the concept of function in a group of students with
a Bachelor's degree in Mathematics. The results
showed benefits in the process of conceptual
appropriation.

Elementos asociados al nivel de desarrollo del pensamiento lógico matemático en la formación inicial de docentes; Elements associated with the level of development of mathematical logic thinking in the initial training of teachers
Ramirez Leal, Pastor; HERNANDEZ SUAREZ, CESAR AUGUSTO; Prada Nuñez, Raul
El presente estudio busco, por una parte, evaluar el nivel de
desarrollo del pensamiento lógico matemático a través de la
aplicación de una adaptación del Test of Logical Thinking
(TOLT) y por otro lado se busca evaluar algunos de los
elementos asociados a este estadio de desarrollo. Se utilizó
la versión española denominada Test de Razonamiento
Lógico-Matemático (TRLM), de TOLT. En función de los
objetivos propuestos, se hizo un diagnóstico del nivel de
desarrollo del Pensamiento a través del test de TOLT: con
una fase cuantitativa para la aplicación del test y luego
determinar las puntuaciones y los análisis comparativo por
variables sociodemográficas a 103 estudiantes de
licenciatura de matemáticas. Los resultados revelan que sólo
una baja proporción de los estudiantes se encuentra en el
nivel de pensamiento formal y en nivel de pensamiento
concreto la gran mayoría del grupo. La edad del estudiante y
la motivación previa en matemáticas se consideran
elementos estrechamente relacionados con el nivel de
desarrollo del pensamiento lógico.; The present study seeks, on the one hand, to evaluate the
level of development of mathematical logical thinking
through the application of an adaptation of the Test of
Logical Thinking (TOLT) and on the other hand it seeks to
evaluate some of the elements associated with this stage of
development. We used the Spanish version called the
Logical-Mathematical Reasoning Test (TRLM), from TOLT.
Based on the proposed objectives, a diagnosis was made of
the level of development of Thought through the TOLT test:
with a quantitative phase for the application of the test and
then determine the scores and comparative analysis by
sociodemographic variables to 103 undergraduate students
of mathematics. The results reveal that only a low proportion
of the students is in the level of formal thought and level of
concrete thought the great majority of the group. The age of
the student and the previous motivation in mathematics are
considered elements closely related to the level of
development of logical thinking.

Construcciones sociales en torno a las ciudadanías: una mirada a su concepto y práctica; Social constructions around citizens: a view of its concept and practice
garcía, cristhian; Rincón, Nydia María
El presente escrito realiza un análisis de revisión sobre las dimensiones de la ciudadanía. Contribuye a reconocer de qué manera
se ha venido trabajando en torno al concepto y las prácticas de ser
ciudadano o ciudadana en diferentes contextos sociales (económicos, políticos y culturales). De esta forma, el documento rastrea
las formas de concebir la ciudadanía en las diferentes épocas de la
historia y enfatiza en las nuevas construcciones desarrolladas en la
actualidad. Finalmente, se aproxima a un abordaje de la ciudadanía
en cuanto construcción social fruto de las intersubjetividades de los
seres humanos con otros seres humanos y con las instituciones que
conforman las sociedades en cada momento histórico.; This paper analyzes the dimensions of citizenship, helping to recognize
how work has been done around the concept and practices of being a citizen
in different social, economic, political and cultural contexts. In this way,
the document traces the ways of conceiving citizenship in different periods of
history and emphasizes the new constructions developed today. Finally, we
will refer to a theme of citizenship as a social construction resulting from
the intersubjectivities of human beings with other human beings and the
institutions that make up societies in each historical moment.

Problems of production lines in parallel machines with lapses: Mathematical modelling
HERNANDEZ SUAREZ, CESAR AUGUSTO; Prada Nuñez, Raul; Prada, R
Production programming consists of assigning, sequencing and timing tasks leading
to the acquisition of physical assets in productive resources. Normally, we talk about "jobs" to
be sequenced in "machines" so that the result of the production programming is shown in the
form of a Gantt chart where each job is divided into as many tasks as necessary and each task is
executed in the machines of the factory as technologically necessary. In the productive reality
several machines are observed in each stage of the production process, which suggests a problem
of hybrid flow workshop type (HFS). However, in some companies a machine of each stage is
joined by conveyor belts. All these machines would behave like a single virtual machine since
the works enter in order in the first machine and that order is maintained until the last machine,
without allowing neither stops nor changes in the sequence. Then in a modelling approach, it is
suggested to reduce the problem of (HFS) to a problem with several production lines in parallel
where each line would behave would be basically like a virtual machine. The problem is that
since the line is so long, once the last element of a job leaves the first stage, it can start the
processing of a new job while the first sequenced work moves through the production line.
Effectively, the "parallel machine" modelling the line would be processing more than one job at
the same time, that is, overlaps between the processed jobs are evident. The model is evaluated
with the help of two of the commercial solvers and to be able to evaluate it, it was necessary to
create a set of instances that would represent the situation under study.
