Con base en el análisis de los resultados obtenidos, se diseñó y probó una secuencia de enseñanza aprendizaje con el objeto de propiciar un conocimiento más significativo de las causas y efectos del fenómeno ambiental. Los resultados muestran una mejoría en varios de los aspectos analizados, sin embargo, se recomienda contemplar el estudio de estos temas de manera integral en los currículos del bachillerato.]]></p></abstract>

Based on the analysis of the results obtained, a teaching-learning sequence was designed and tested in order to promote a more significant knowledge of the causes and effects of the environmental phenomenon.
