“…In contrast to the experiences of students of the conventional group, interview responses indicated that students of Autographassisted lessons were able to observe, visualise, recognise, and comprehend geometric shapes with variant and invariant properties which provide them with spatial reasoning abilities to make conjectures and generalisations. These findings corroborate with the conclusions of Akgül (2014), and Çekmez (2020) that dynamic geometric software provides an interactive interface which offers students multiple opportunities to explore and realise the existence and preserve of geometric relationships in different figures.…”

The use of technology as a pedagogical practice is growing at a phenomenal rate due to the availability of numerous computer mathematics software. As a result, conscientious efforts need to be made by teachers to integrate technology effectively to enhance the teaching and learning processes and consequently learning outcomes of students. This non-equivalent quasi-experimental study sought to explore students’ achievements and their attitudes after using a dynamic Autograph software technology to learn circle theorems. One hundred and fourteen Senior High School students purposively selected from three different schools participated in the study. While students from two of the schools were taught using the Autograph technology in a social-interaction and self-exploration environment respectively, the group of students from the last school were taught conventionally without the use of the Autograph technology. The findings of this study showed that the three teaching strategies had a significant positive effect on students’ achievements. However, the social-interaction Autograph-assisted group significantly outperformed, followed by the self-exploration Autograph-assisted group, and then the conventional group. The study also showed that though the self-exploration group showed higher positive attitudes than the social-interaction, the Autograph-assisted groups in general reported overall positive attitudes towards using the technology indicating further that the Autograph-support made lessons practical, stimulating, and provided imagery simulations and multiple representations that enhanced visualisation and understanding. Implications of the Autograph technology use in teaching, while engaging students in small groups are discussed.

“…El agua por encima de su temperatura y presión crítica (374°C, 22 MPa) tiene especial importancia en la conversión de la biomasa debido a que, los enlaces de hidrógeno por molécula de agua disminuyen gradualmente a medida que el proceso avanza hacia las condiciones supercríticas, convirtiéndose en un buen disolvente para las moléculas orgánicas (Akgül, 2014).…”

Introducción: los residuos agrícolas están aumentando en todo el mundo, siendo necesario identificar nuevas estrategias para su valorización. Objetivo: analizar los principales procesos de transformación de biomasa para ser implementados en el aprovechamiento de los residuos de la agroindustria del plátano. Metodología: la consulta de la información se realizó en diferentes bases de datos como: Web of Science, Scopus y Google Scholar. Se utilizaron diferentes palabras claves en inglés y español como: “waste”; “process”; “transformation”; “banana” and “plantain”. La información se analizó en MS Excel. Resultados: los procesos de conversión física y biológica pueden ser una alternativa para la valorización de los residuos de la agroindustria del plátano en diferentes productos de valor agregado como alimentos para animales y biocombustibles debido a la cantidad y composición de este tipo de residuos. El alto contenido de humedad de estos residuos puede representar un inconveniente para su aprovechamiento. Es necesario extraer agua de la matriz para aumentar la eficiencia en la transformación. Conclusiones: diseñar y evaluar tecno–económica, ambiental y socialmente los procesos de transformación físicos y biológicos en el contexto de las biorrefinerías puede apoyar la toma de decisiones de inversión e investigación en este tipo de tecnologías para ser implementadas a nivel industrial.
