ABSTRACT
The purpose of this study was to evaluate two versions of a programmed instruction training program designed to teach undergraduate college students a goal-directed systems approach to analyzing organizational systems (Malott & Garcia, 1987). The first version was a paper-based programmed instruction module that had previously been shown to be effective at training the basic knowledge of the concepts, however was ineffective at training the application of these concepts. A computer-based programmed instruction (CBPI) version was created to improve the application of these concepts, which was tested through a series of three open-ended posttests with increasingly explicit prompts for each successive test. The results of the study showed higher performance results for the CBPI versions across all three dependent variables. The results of a nonparametric global test showed a standardized effect size of .86 and a p-value of < .001.
El propósito de este estudio fue evaluar dos versiones de un programa de instrucción programada diseñado para enseñar a estudiantes no graduados una aproximación al diseño de sistemas dirigidos a metas para analizar sistemas organizacionales (Malott & Garcia, 1987). La primera versión consistió en un modulo de un programa de instrucción personalizada de papel que anteriormente había probado ser efectivo para enseñar conocimientos básicos de conceptos, pero que no obstante era ineficiente para entrenar en la aplicación de dichos conceptos. Se creó una versión computarizada de instrucción programada (CBPI) para mejorar la aplicación de los conceptos, la cual se probó a través de una serie de tres post-tests con respuestas libres que incluyeron pistas cada vez más explícitas en cada prueba sucesiva. Los resultados del estudio mostraron una mejor ejecución en las tres variables dependiente cuando se usaron las versiones del CBPI. Los resultados de una prueba no paramétrica global mostraron un tamaño del efecto estandarizado de .86 y un valor p < .001.
ABSTRACT
Purpose: Use of technology to integrate pathology teaching in the third year of medical training. The teaching of pathology and disease includes several sections that have been taught by separate departments of immunology, haematology, microbiology, histopathology and biochemistry. It has been noted that students are not able to integrate the teaching from all these departments. To address this problem we have developed a model to integrate the teaching of the different sections by providing additional cases and materials in the computer laboratory. Methods: The eight week course of general pathology has been chosen for this model as it is the first section of pathology and the availability of teaching materials in the server of the computer. Three practical sessions are given to each section, histopathology, microbiology, haematology, immunology and clinical chemistry. Additional information was made available to students in the new thin client computer laboratory. A questionnaire was administered at the end of the course to half of the students. The responses which targeted in three areas, content, relevance, and acceptance and analyzed. Results: The eight week course was received enthusiastically by the students. The data indicated that the students generally accepted a computer-based instruction in teaching pathology. There was no improvement in performance of the class at the end of the term examinations as compared to the previous year. Conclusions: Computer-based instruction is possible in low resource countries. Use of technology can address challenges relating to integration of teaching .This model could serve as a nucleus for more extensive restructuring of teaching in the entire Medical School as well in other Medical Schools in Kenya and the rest of Africa.
