This paper presents an educational design that develops, implements, and evaluates certain educational games to support teaching and learning biology in secondary school. A quasi-experimental design was employed in which biology was taught to an experimental group using educational games while a control group was taught using traditional methods. The quasi-experiment was conducted in the first year of a technical high school, with two biology teachers assigned to each of the groups involved in the study. Both the control group and the experimental group consisted of 40 students. The study used observation guides, surveys, and questionnaires to collect data. The results demonstrate that educational games positively impact the teaching and learning of biology.

Esta investigación tiene como objetivo fortalecer el aprendizaje de la Biología a través de prácticas experimentales en los estudiantes de bachillerato. Se realizó un diseño cuasiexperimental, con enfoque mixto, cualitativo y cuantitativo, con una metodología explicativa, descriptiva, de campo y comparativa, mediante los métodos inductivo‐deductivo y descriptivo. La muestra fue de 56 estudiantes divididos en un grupo experimental y un grupo de control. Para determinar diferencias entre las notas obtenidas en los test de glúcidos, lípidos, proteínas y ácidos nucleicos se empleó la prueba U de Mann Whitney, y la prueba Wilcoxon se utilizó para establecer si existían diferencias significativas entre el pretest y postest de biomoléculas en cada grupo con un nivel de significancia p<0.05. Al comparar los resultados del pretest y el postest se puede evidenciar que las prácticas experimentales tienen un impacto significativo en el rendimiento académico de los estudiantes. En conclusión, las prácticas experimentales áulicas mejoran en gran medida el rendimiento de los estudiantes

Waste managing plan for floriculture plants

Ecuador's Floriculture Industry is essential as one of the biggest flower producers exporting flowers worldwide. However, flower production generates harmful environmental waste, emitting greenhouse gases. Therefore, it is vital to implement sustainable practices. In this document, an analysis of the supply chain will be conducted to provide a cleaner production system and efficiency for the Floriculture Industry. The objective is to reduce the harmful impact on the environment, searching solutions to minimize water use and develop energy-efficient technology. As a result, we look forward to sustainable flower production, protecting the environment and natural resources.
