El aprendizaje basado en el juego y el uso de tecnologías de la información mejora las habilidades y aprendizaje de las matemáticas universitarias. Este estudio pretende validar una técnica de aula llamada “El Rompecabezas” en estudiantes de ingeniería industrial desde las asignaturas cálculo diferencial e integral, apoyado en el aprendizaje activo y colaborativo. Se elaboró un rompecabezas con una plantilla digital, la cual se aplicó a equipos conformados donde el ganador tuvo un incentivo académico. Es un estudio experimental en el cual se analizaron aspectos sociodemográficos de los estudiantes y se aplicó un pretest y postest para evaluar la efectividad de la técnica en el aula. Se utilizó una muestra intencional con un total de N= 178 estudiantes pertenecientes a las asignaturas cálculo diferencial e integral de los años 2016 a 2020. Los datos sociodemográficos de los estudiantes se analizaron con estadística descriptiva y se utilizó el software estadístico SPSS Statistics versión 25 con la prueba no paramétrica de Wilcoxon para muestras relacionadas y poder medir las mejoras, producto de la aplicación de la técnica. Los resultados del pretest y postest refieren diferencias e indican que la aplicación de la técnica de aula “El Rompecabezas” mejora significativamente el aprendizaje del proceso de derivación e integración. Los resultados de este estudio coinciden con otros trabajos donde las estrategias didácticas mejoran el aprendizaje, además esta técnica puede ser un referente para ser aplicada en otras asignaturas y promover actividades de este tipo en el aula.

Citizen science resources have had great relevance in community educational intervention, fostering interest in ecological research projects. This study investigated the influence of the application of multimedia didactic resources focused on citizen science and analysis of sociodemographic variables to improve the levels of ecological knowledge about mosquito-borne diseases. For this, a probabilistic sample of 172 participants from an urban sector in southwestern Colombia was selected. A multimedia didactic material was designed for the educational intervention and evaluated by means of pretest and posttest. To assess whether the educational intervention was statistically significant, the data were processed with statistical inference to determine the influence of various variables (gender, age, marital status, schooling, and occupation) on each person’s ecological knowledge. The findings showed a significant increase in the knowledge levels of the participants. The marital status variable (married and cohabiting) significantly influenced ecological knowledge. These participants are more likely to obtain high knowledge, associated with the prevention of their family environment. This study demonstrated that multimedia didactic strategies are an important factor to take into account in the structuring of environmental education and citizen science projects. For future research, it is suggested to deepen the relationship between sociodemographic variables and ecological knowledge.

Background: Mosquito-borne diseases (MBD) continue to represent a critical public health challenge, particularly in tropical regions where environmental and socioeconomic factors facilitate transmission. Methods and materials: This study assessed the knowledge, attitudes, and practices (KAP) related to MBD among 172 residents of an urban area in Santander de Quilichao, Colombia. A structured survey, validated and adapted from the Pan American Health Organization, was performed for data collection. Results: The mean knowledge score was 57%, indicating moderate awareness of MBD. While 63.4% of participants reported adequate preventive practices, the majority (94.8%) demonstrated indifferent attitudes toward MBD prevention. Multinomial logistic regression analysis revealed a statistically significant association between marital status and knowledge levels ( p < 0.05), with married participants exhibiting higher knowledge. Socioeconomic analysis showed that 41.3% of participants earned the legal minimum wage, and 68.6% of households included at least one woman of childbearing age. Despite moderate knowledge and preventive practices, the prevalence of indifferent attitudes may hinder effective MBD prevention. Conclusion: These findings emphasize the need for targeted community engagement and educational interventions. Incorporating KAP assessments into public health strategies can enhance the design and implementation of effective educational and vector control programs in urban areas of tropical countries.

The Culicidae family (mosquitoes) has great relevance worldwide, due to its involvement in the generation of several diseases. The department of Cauca in Colombia characterize as a region with influence of several vector-borne diseases. The purpose of this study is to analyze the ecological diversity and distribution of mosquitoes with potential transmitters of diseases in a particular urban area of the municipality of Santander de Quilichao. This is one of the first studies of its kind in this municipally. Mosquito collections were carried out during the rainy and dry seasons of 2022, between 17:00 to 19:00. Morphological keys were used for species identification. For the analysis of diversity comparison vs. sampling points, Simpson's index was used, dendrogram, rarefaction curve and non-metric multidimensional scaling (nMDS). In the statistical analysis of species-abundances, ANOVA were applied to determine if there were significant differences regarding abundance. A total of 1116 culicid specimens were collected. The 59.4% were mosquitoes of the species Aedes aegypti, 18.5% Culex quinquefasciatus, 18.2% Aedes albopictus and 3.9% Psorophora ferox, being the rainy season important for their survival. ANOVA analysis showed that the mean abundance of Aedes aegypti was significantly different from the other species. This study is broadly consistent with other studies in the tropical American context where the abundance of Culicidae is more representative in the rainy season. The results suggest a wide presence of Aedes mosquitoes in natural and artificial habitats, showing the importance of establishing controls and permanent epidemiological surveillance in this region.
