Research and Publish. 2. Answering the Question: Study Design / Investigar y publicar. 2. Cómo responder la pregunta "diseño del estudio"

Abstract Introduction: Study design guides the methodology for obtaining an answer to a research question. Understanding the different types of research, their advantages, and disadvantages will help ensure the validity of our results. Objective: To describe experimental and non-experimental research designs, along with their respective advantages and disadvantages, in order to guide researchers in selecting the most appropriate design based on their research question. Results and Conclusions: The literature is reviewed to describe the main characteristics, the simplest and most useful classifications for determining the best study design. The study population, internal and external validity of the studies are also determined, in order to understand, based on our research question, the possible extrapolation of our results.

Resumen Introducción: El diseño del estudio dirige la metodología para obtener la respuesta a la pregunta de investigación, y tener claro cuáles son los tipos de investigación, sus ventajas y desventajas, ayuda a la validez de los resultados. Objetivo: Describir los diseños de investigación experimental y no experimental, las ventajas y desventajas de cada uno de estos diseños con el fin de guiar al investigador a la mejor escogencia de este con base en la pregunta de investigación. Resultados y conclusiones: Se revisa la literatura con el fin de describir las características principales, las clasificaciones más sencillas y de mayor utilidad para determinar el mejor diseño de estudio. Se determina además la población de estudio, validez interna y externa de los estudios a fin de entender, basados en la pregunta de investigación, la posible extrapolación de los resultados.

"Application of ""Flipped Classroom"" and Experiment Project Modular Design in the Instrumental Analytical Experiment Teaching" / 中国药房

OBJECTIVE:To improve the effectiveness of experimental teaching and independent hands-on ability of the students.METHODS:Combined with teaching characteristics of newly established universities,the characteristics of instrumental analytical experiment teaching and the characteristics of pharmaceutical students,flipped classroom and project modular design were applied to instrumental analytical experiment teaching together.The instrumental analytical experiment teaching was expounded and integrated in respects of curriculum content design,teaching implementation and curriculum assessment.RESULTS&CONCLUSIONS:The students achieve the knowledge learning after classroom,and complete the knowledge absorption and mastering in class with the help of video and audio information.It also improved independent learning ability of the students,strengthened the ability of interactive learning and cooperative leafing between teachers and students and among students.It is feasible to apply the flipped classroom and the experimental project modular design in the instrument analytical chemistry experiment teaching reform.This method also can provide some references for the reform of instrument analytical chemistry experiment teaching.
