Once the learner has completed viewing the demonstrations of each principle they can practice recognizing situations in which the principle is applicable. The practice of retrieving this information will help the learner to retain the information in long term memory.
1. Using the “Drug Options” tab the student can practice replicating the basic principles by selecting a range of patient variables, routes of administration and drug dosages. The learner begins by stating the principle they want to replicate.
2. As the learners experience the applications of the principles they are encouraged to focus their attention on the direction and magnitude of change which occurs in the ‘blood concentration time curve’ (see green arrow in figure 3) or area under curve (AUC) as a result of a variable being changed. Unless attention is given to this information it will be lost from memory.
3. After sufficient practice the student will be able to identify the features of the situation that suggest a particular principle is being applied and become proficient in correctly explaining, predicting and controlling the effect of these changes on the patient. In order to shift the principle that is being learned from short-term memory to long-term memory the steps which were taken to generate the principle must be rehearsed within 30 seconds.
The memory model for the 3 steps of the practice phase are illustrated in figure 4.
