Challenges of Shaping Student Study Strategies for Success: Replication and Extension

We replicated and extended Maurer and Shipp’s (2021) intervention to teach students the successive relearning study strategy and encourage its use in preparation for course exams. This mixed-methods project was conducted in partnership between the faculty member teaching the course and an undergraduate student enrolled in the course. Results were similar to those reported by Maurer and Shipp (2021) but differed in meaningful ways. In this investigation, students reported more spaced practice in studying for the exam, demonstrated both greater confidence and greater mastery of the targeted course concept and closer alignment of confidence and mastery. They also reported greater unprompted metacognitive awareness of their own need to learn better study strategies. Qualitative responses from students aligned with the recommendation from SoTL literature that interventions to teach students to adopt more effective study methods need to both provide information and research evidence about more effective methods to students. The responses also aligned with the recommendation from SoTL literature to scaffold students through how to use the methods with opportunities to practice them. Time management issues emerged as the largest student-identified barrier to adopting successive relearning. Click here to read the corresponding ISSOTL blog post.

Rediseño del sistema de alcantarillado combinado y diseño de planta de tratamiento de aguas residuales para el barrio Selva Alegre, ubicado en la parroquia de Sangolquí, cantón Rumiñahui, provincia de Pichincha

Se propone el rediseño del sistema de alcantarillado combinado y diseño de la planta de tratamiento de aguas residuales para el barrio Selva Alegre, cumpliendo con la normativa establecida, esto con la finalidad de proporcionar una red de alcantarillado segura y confiable para la población, y garantizar una descarga libre de contaminantes al río Santa Clara. Para el diseño del alcantarillado se realizan cálculos hidráulicos, estudios sociales e hidrológicos con la finalidad de obtener un caudal combinado máximo horario acumulado de 2.993⁄, que es conducido hacia la planta depuradora a través de un colector. Para la planta de tratamiento de aguas residuales se diseña unidades de pretratamiento, tratamiento primario y tratamiento secundario, conformada por las siguientes estructuras: separador de caudales, canal de ingreso, cribado mediante rejillas, desarenado-desengrasado, tanque Imhoff y filtro percolador de flujo ascendente. Para el tratamiento de lodos provenientes de las unidades depuradoras se diseña un lechado de lodos y antes de su descarga final, un tanque purificador. Finalmente, se presenta un presupuesto referencial y planos de la red de alcantarillado y la planta de tratamiento.The present project proposes the redesign of the combined sewerage system and design of the wastewater treatment plant for the Selva Alegre district, located in the parish of Sangolquí, in compliance with the regulations established, this with the aim of providing a safe and reliable sewerage network for the population, and ensuring a without discharge of contaminants to the Santa Clara River. For the design of the sewerage system, hydraulic calculations, social studies and hydrological studies are carried out in order to obtain a final accumulated maximum hourly combined flow of 2.993⁄, that is carried to the treatment plant through a collector. For the wastewater treatment plant, pretreatment, primary treatment and secondary treatment units are designed, consisting of the following structures: Flow separator, inlet channel, screen by grating, de-greasing, Imhoff tank and upstream percolator filter. For the treatment of sludge are designed sludge drying tank and before final discharge a disinfection tank. Also, a benchmark price and plans for the sewerage network and treatment plant are presented

Construction of Bioreactors for Obtaining Mycelium from Agaricus Brunnescens and Pleurotus Ostreatus Mushrooms Using the Honey Tek Technique

Mycelium cultivation plays an important role in mushroom production and in various biotechnological studies. Submerged fermentation has received much attention as a promising alternative for the efficient production of mushroom biomass and active metabolites. For the following research, bioreactors were constructed to obtain pure mycelium from Pleurotus ostreatus and Agaricus brunnescens mushrooms using the Honey technique. This method is based on using honey as the main nutrient for the growth of microorganisms on an industrial scale. In the beginning, spore impressions were extracted by the dry chamber method and inoculated into the honey broth. The bioreactors were dimensioned with a 2.5 L culture chamber, 2 L production, controlled temperature of 28∘C, pH = 4, and agitation of 120 revolutions per minute. Conidia/milliliter was quantified every three days with a Neubauer chamber, and the Kjeldahl method was used to identify protein as the main bioactive metabolite of the mycelium. Finally, the mycelium obtained was evaluated on three types of substrates comparing their colonization time. The use of bioreactors in mycelium cultivation is efficient as better mycelium quality, higher biomass yield, and more dispersion on substrates are obtained. It also has the benefits of much better oxygen mass transfer and culture homogeneity. With this technique, physical, chemical, and biological factors can be controlled to produce mushrooms in a much shorter time. Keywords: bioreactor, honey technic, mycelial biomass, Agaricus brunnescens, Pleurotus ostreatus. Resumen El cultivo de micelio juega un papel importante en la producción de hongos y en diversos estudios biotecnológicos, el usar la fermentación sumergida ha recibido mucha atención como alternativa prometedora para la producción eficiente de la biomasa de hongos y metabolitos activos. Para la siguiente investigación se construyeron biorreactores con el objetivo de obtener micelio puro de hongos Pleurotus ostreatus y Agaricus brunnescens usando la técnica Honey. El método Honey se basa en aprovechar la miel como nutriente principal para el crecimiento de microorganismos a escala industrial. En principio se extraen impresiones de esporas mediante el método de cámara seca y se inoculan en caldo honey. Los biorreactores se dimensionaron con una cámara de cultivo de 2,5 litros, producción de dos litros, temperatura controlada de 28 grados Celsius, pH igual a cuatro y agitación de 120 revoluciones por minuto. Se cuantificaron los conidios/mililitro cada tres días con una cámara de Neubauer y se usó el método Kjeldahl para identificar la proteína como principal metabolito bioactivo del micelio. Finalmente, el micelio obtenido fue evaluado sobre tres tipos de sustratos comparando su tiempo de colonización. El uso de biorreactores en el cultivo de micelio es eficiente debido a que se obtiene mejor calidad de micelio, mayor rendimiento de biomasa y más dispersión sobre sustratos. Así mismo, posee los beneficios de una transferencia de masa de oxígeno y una homogeneidad de cultivo mucho mejores. Con esta técnica se pueden controlar factores físicos, químicos y biológicos para producir setas en tiempos mucho más cortos.
