| description | A large group together with the fact that organic chemistry is commonly regarded as difficult creates challenges for the instructor. In this paper we describe the evaluation of the effectiveness of implementing Web 2.0 tools in organic chemistry lecture on students' understanding of basic concepts in comparison with the absence of such tools in large groups. The study used a mixed method design that encompassed 537 students in six separate sections of two courses, four accelerated and two general organic chemistry courses. All the sections but three experienced the standard lecture environment without intervention. The intervention consisted of a blog designed specifically for this research, which used entries regarding key concepts with selected videos. Instructors and students were invited to respond to various instruments for research data gathering. Those instruments included questions concerning previous knowledge of chemistry, covered information to acknowledge the use of Web 2.0 by instructors and students, and involved items to discover whether the tools were perceived useful for the students. The study used only data from the students who attended class on a regular basis and completed the test and the questionnaires. The impact of the use of Web 2.0 on student achievement was obtained from the students' grades on the first examination of the term. The participants' perception was that the tools are useful for the teaching-learning process and the blog and videos had a positive impact on their academic performance |

En este artículo se describe la evaluación de la efectividad del uso de herramientas Web 2.0 en las clases de química orgánica para apoyar la comprensión de conceptos básicos por parte del estudiantado, en comparación con la ausencia de ellas. El estudio utilizó un diseño mixto que abarcó a 537 estudiantes en cuatro grupos de Fundamentos de química orgánica y en dos de Química orgánica general. Todos los grupos, excepto tres, experimentaron el ambiente estándar de la clase sin intervención. La intervención consistió en un blog diseñado específicamente para esta investigación, el cual contenía videos sobre conceptos clave. Tanto instructores como estudiantes fueron invitados a responder diversos instrumentos para la recolección de datos. Dichos instrumentos incluyeron preguntas sobre conocimientos previos de química e información sobre el uso de Web 2.0 por parte de instructores y estudiantes. Asimismo, se incluyeron consultas para descubrir si las herramientas eran percibidas como útiles. El estudio utilizó solo datos del estudiantado que asistió a las lecciones de forma regular y completó la prueba y los cuestionarios. El impacto del uso de Web 2.0 en el rendimiento estudiantil se valoró con las calificaciones obtenidas en el primer examen del semestre. La percepción de las personas participantes fue que las herramientas son útiles para el proceso de enseñanza-aprendizaje y que el blog y los videos tuvieron un impacto positivo en su desempeño académico Universidad de Costa Rica 2019-01-01 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Article application/pdf text/html https://revistas.ucr.ac.cr/index.php/aie/article/view/35589 10.15517/aie.v19i1.35589 Actualidades Investigativas en Educación; Vol. 19 No. 1: (Enero - Abril); 31 Actualidades Investigativas en Educación; Vol. 19 Núm. 1: (Enero - Abril); 31 Actualidades Investigativas en Educación; v. 19 n. 1: (Enero - Abril); 31 1409-4703 spa https://revistas.ucr.ac.cr/index.php/aie/article/view/35589/36176 https://revistas.ucr.ac.cr/index.php/aie/article/view/35589/38443 Derechos de autor 2018 Actualidades Investigativas en Educación http://creativecommons.org/licenses/by-nc-nd/4.0 |
