The study’s goal was to provide an educational intervention in Algebra through GeoGebra that would boost students’ confidence, improve their learning, and correct their most minor mastered skills, allowing them to improve their Algebra performance. The research design was quasi-experimental, with 40 nonrandomly chosen participants comprising the GeoGebra and control groups. Mean and standard deviation was employed to describe the algebra performance and confidence of the respondents. At the same time, independent and dependent t-tests were used to determine (...) the students’ significant difference in algebra performance and confidence in the pre-and post-test between the control and GeoGebra groups. GeoGebra effectively improved algebra confidence, enhanced learning, and remedied the students’ least mastered skills. GeoGebra is recommended as an instructional material in teaching and learning Algebra and can be extended to other mathematics content areas. (shrink)

This paper aims to address the difficulties of high school students in bridging their computational understanding with their visualization skills in understanding the notion of the limits in their calculus class. This research used a pre-experimental one-group pretest-posttest design research on 62 grade 10 students enrolled in the Science, Technology, and Engineering Program (STEP) in one of the public high schools in Zamboanga del Sur, Philippines. A series of remedial sessions were given to help them understand the function values, one-sided (...) limits, limits of a function, and its discontinuities with the aid of the GeoGebra. Results revealed that there is a significant improvement in their mathematics performance before and after the remediation, t(61) = -19.99, p<.05. The real-time feedback provided by the drawing interface of GeoGebra has provided the students the insights into how objects behave in geometrical space, bridging their understanding in locating the values shown by the computational algebraic processes. Additionally, the significant difference in the achievement reveals a large effect size (Cohen’s =2.54) which could be accounted for by the remediation using interactive activities in the GeoGebra.

El artículo pretende provocar un acercamiento a la enseñanza de la estadística descriptiva y probabilística, con el diseño de experiencias didácticas basadas en experiencias de maestros que aprenden de maestros a través de la implementación de tecnologías de información y comunicación, con el fin de implementar un recurso concreto para la modelación y estructuración de situaciones en las que las diferentes distribuciones de probabilidad se pueden implementar pedagógicamente. Como estrategia pedagógica, se persigue más que “hacer datos”, conseguir la familiaridad del (...) concepto, con el cual los estudiantes colombianos están enfrentados en particular dentro del componente de estándares básicos de pensamiento aleatorio y variacional (MINISTERIO DE EDUCACIÓN NACIONAL -MEN-, 2006). La estrategia, para el cuerpo de docentes del área de matemáticas y estadística, constituye una metodología dirigida a la conformación de un banco de alternativas innovadoras para trabajar didácticamente en estos conceptos tanto en su didáctica, como en su forma de implementar el software libre GeoGebra. La perspectiva de la propuesta se materializa en la expresión reflexiva de estrategias de enseñanza continuamente mejoradas. En cuanto a la estadística descriptiva e inferencial, se persigue el desarrollo de actitudes positivas de maestros y de estudiantes frente a la cotidianidad y al mundo de la vida, en donde las actividades suelen involucrar situaciones contextualizadas en las que se demanda del lenguaje estadístico.
