The purpose of this study was to develop an Electronic Performance Support System (EPSS) to improve students’ knowledge and performance in the Basic Life Support (BLS) course. This study was planned and carried out as a developmental research. The participants of the study were composed of medical-dental students and experts. Academic achievement test, performance test, expert evaluation form and interview form were used as data collection tools. Findings showed that the students taught using the EPSS have higher levels of academic achievement and performance compared with the students taught using the lecture format in a traditional way of teaching. Students stated that the system was useful and effective. EPSSs like present system, which was developed without any cost and using advanced programming, can be used for supporting learning. The used framework in this study can provide guidance for future works.
STEM education, which advocates the application of different fields such as Science, Technology, Engineering, and Mathematics (STEM) by using an interdisciplinary approach, has become a phenomenon that addresses the needs of our century. In this study, I aimed to determine the views of pre-service science teachers about STEM education. I conducted a two-hour Arduino based STEM learning activity for fifteen pre-service science teachers. Afterward, I investigated further the views of the participants by conducting an online survey consisting of open-ended questions. Finally, I analysed the data obtained with content analysis technique using NVivo 12. As a result of the analysis, it was concluded that pre-service teachers do not know the content of the STEM approach but at the same time, they think that STEM education should be applied in schools, and they want to learn how STEM can be used in classes. Based on the results, it is suggested that it may prove beneficial to provide professional development to pre-service teachers regarding the content of the STEM approach.
Introducción: Debido a la complejidad de los estudios y la preferencia cognitiva por la información visual, las tablas y figuras son formas idóneas para presentar datos organizados, y una herramienta poderosa para comunicar y comprender los hallazgos de la investigación médica. Sin embargo, existe poca información de como deben de ser construidas y presentadas correctamente las tablas y figuras. Objetivo: Sintetizar la información disponible para diseñar, construir y leer tablas y figuras en las publicaciones médicas. Método: Se realizó una busqueda de la literatura y se presentan los resultados sintéticos. Resultados y Conclusiones: Las tablas y figuras son la mejor forma de presentar datos de manera sintetica y clara, además de que se logra una mayor comprensión de los datos por el lector al permitir encontrar tendencias, diferencias y desarrollar una conclusión propia a partir de los mismos. Se deben presentar datos y figuras solo en situaciones especificas. El número total de figuras o tablas es 1 por cada 1000 palabras del texto, si ha sido publicada previamente, hay que refereir a la fuente original. Se desarrollo un método de 5 pasos para la lectura e interpretacion correcta de tablas y figuras: Identificación estructural: (Orientación), ¿QUÉ significan los números? (Identifica los valores individuales), ¿COMO cambian los datos y DONDE lo hacen?, ¿POR QUE cambian los datos? Y por ultimo, APLICACIÓN de la información.
RESUMEN\nEl contenido básico de este artículo se centró en analizar, algunos momentos que identifican la\nactividad de control a una clase universitaria en Cuba. La esencia del control a “una clase”, es \nretroalimentarse sobre la calidad de la instrucción y la educación del proceso formativo que \ntranscurre; de ahí, la relevancia del tema. Los métodos de investigación empleados han sido: el \ninductivo deductivo, analítico sintético, análisis documental, y la observación científica\nestandarizada. Como resultados alcanzados: se esclareció lo que plantean los documentos \nrectores con relación al control a clase; se dilucidó la polémica de si el control es al profesor,\no al evento clase; se esclareció qué aspectos se consideran esenciales y pudieran afectar la\ncalificación del control; se identificó cómo debe actuar un profesor en una clase controlada\npara satisfacer las exigencias establecidas, y se esclarecieron las partes de una clase que se \ndeben respetar, para que dicha actividad tenga la calidad exigida. Estos resultados han sido \nsignificativos, toda vez que han permitido capacitar a potenciales “controladores” y orientar a \nlos “controlados”, lo cual se tradujo en un crecimiento de la calidad del proceso docente \neducativo. El objetivo que pretenden los autores consistió en orientar al personal docente en \ngeneral (autoridades universitarias y docentes sometidos a la actividad de control), sobre los \naspectos básicos que se deben tener en cuenta para realizar un control a clase en la enseñanza \nsuperior cubana, y obtener resultados de excelencia. Este trabajo puede interesar a lectores de \nmás de una disciplina del ámbito nacional e internacional.\nPalabras clave: control, clase, proceso.
The strong relation between learner autonomy and second/foreign language learning is well documented. It is also believed that successful language learners display the characteristics of autonomous learners. The current study examined the degree of learner autonomy and the relation between autonomy beliefs and autonomy practices of Saudi EFL university students. It also detected the major obstacles against their autonomy. In this quantitative study, a survey questionnaire was administered to 350 (N=350) students in the English Language Center of King Khalid University, Saudi Arabia. The findings revealed that Saudi EFL learners are autonomous (average Mean: 3.67 and Standard Deviation: 1.268). Statistical analysis (i.e., paired t-test, and correlation test) detected a statistically significant positive relationship (r = 0.668, p < .05) between Saudi EFL learners’ autonomy beliefs and autonomy practices. The study also highlighted the major obstacles that Saudi EFL learners encounter in achieving autonomy. These findings have some pedagogical implications.
Here hydromagnetic mixed convective flow of viscous nanoliquid due to rotating disk is addressed. Slip condition is to be account. Joule heating and thermal flux are discussed in heat equation. Furthermore random motion and thermophoresis impacts are accounted. Additionally irreversibility analysis in binary chemical reaction is scrutinized. Bejan number is calculated. The governing equations are transformed by using suitable similarity variables. ND-solve method is used to get the convergent solution. Influences of sundry variables on velocity field, entropy rate, temperature distribution, Bejan number and concentration are deliberated. Performance of Sherwood and Nusselt number are examined. An opposite trend is seen in temperature and velocity field for magnetic parameter. Temperature distribution is improved for larger radiation variable. Concentration has reverse trend for thermophoresis and Brownian motion parameters. An increment in radiation variable augments the entropy optimization. Bejan number and entropy rate both have reverse effect versus magnetic parameter.
This article investigates hydromagnetic flow of viscous liquid by a curved stretching surface. Dissipation, radiation and Joule heating effects are deliberated through energy equation. Irreversibility analysis and binary chemical reaction are scrutinized. Here convective boundary and slip conditions are addressed. The concerned PDEs are altered to the ordinary ones through suitable variables. The obtained system is solved employing ND-solve method. Influence of sundry variables on velocity, concentration, temperature, entropy rate and Bejan number are examined. Velocity field is amplified for higher curvature parameter. For larger second-order slip variables the velocity is decreased. Temperature distribution is more against higher curvature and radiation parameters. Higher solutal Biot numbers boost the concentration. Entropy optimization has similar behavior for radiation parameter and Brinkman number
