Resumen
Esta investigación empírica aplica a estudiantes de una institución privada de Lima
Metropolitana, la línea de investigación es “Aprendizaje potenciado por tecnología” y
la sublínea de investigación es “Uso e impacto de recursos tecnológicos en el
desarrollo de capacidades curriculares del área de Ciencias”. El objetivo general fue
determinar en qué medida el uso de laboratorios contribuye en mejorar las habilidades
de indagación científica. La investigación tiene diseño metodológico
cuasiexperimental con grupo experimental y de control con características
equivalentes. Comparando datos del pretest y postest con la prueba de Wilcoxon, del
grupo experimental relacionada a la habilidad de formular pregunta indagatoria e
hipótesis tienen p valor <0.001, cuentan con diferencia significativa. El grupo control
frente a la habilidad de formular preguntas indagatorias e hipótesis tiene valores
p=0.064 y p=0.002, no existe significatividad. Los resultados de la Prueba de
Normalidad no presentan distribución normal. En la Prueba U de Mann Whithney no
existen diferencias significativas al comparar rangos de grupos experimental y control
para la formulación de la pregunta indagatoria tanto en el pretest (p-valor 0.61) como
en el postest (p-valor 0.22), lo mismo se observa al comparar el grupo experimental y
control para la formulación de la hipótesis en el pretest (p-valor 0.45). Comparando
los grupos postest experimental y control para la formulación de la hipótesis se
observa el p-valor <0.001, lo cual es estadísticamente significativo. Concluyendo que
el grupo experimental, fortalece la habilidad indagatoria después de utilizar el
laboratorio virtual.
This empirical research applies to students from a private institution in Metropolitan Lima. The line of research is "Technology-enhanced learning" and the subline of research is "Use and impact of technological resources in the development of curricular capacities in the area of Science." The general objective is to determine to what extent the use of laboratories contributes to improving scientific inquiry skills. The research has a cuasiexperimental methodological design with experimental and control groups with equivalent characteristics. Comparing data from the pretest and posttest with the Wilcoxon test, the experimental group's p-value related to the ability to formulate investigative questions and hypotheses has a value of <0.001, showing a significant difference. The control group's p-values regarding the ability to formulate investigative questions and hypotheses have p = 0.064 and p = 0.002, not showing significance. The results of the Normality Test do not present a normal distribution. In the Mann-Whitney U test, there are no significant differences when comparing the ranges of the experimental and control groups for the formulation of the investigative question in both the pretest (p-value 0.61) and the posttest (p-value 0.22). The same is observed when comparing the experimental and control groups for the formulation of the hypothesis in the pretest (p-value 0.45). Comparing the experimental and control posttest groups for the formulation of the hypothesis, a p-value of <0.001 is observed, which is statistically significant. Concluding that the experimental group strengthens their investigative skills after using the virtual laboratory.
