Ejercicios de cálculos en química aplicada

Research shows that during the last 10 - 13 years the number of students who claim to enjoy solving chemistry exercises has decreased by almost one fifth. One way to make chemistry exercises more interesting for students is to relate the content to real life situations. This article presents a conceptual approach to include practical elements in chemistry exercises. Based on this concept, we have devised an educational model for effectively relating real life to the content of chemistry exercises. The didactic objective of the model is to ensure a link between the student's real life experiences and the chemistry exercise - to include this practical aspect in the exercise and, in turn increase the chances that the student will apply what is learned in the exercise later on in life. Trialling of the model shows that student interest increases if they perceive the exercise as useful, but students still find it difficult to relate their personal experience to chemistry exercises and chemistry in general.
