This study introduces a medication dosage calculation problem-solving (MDC-PS) competence model, linking understanding, computation, and measurement skills. It emphasizes integrating cognitive and functional competence for effective education and error diagnosis in healthcare professionals.
Area of Science:
- Nursing Education
- Health Professions Education
- Pharmacology Education
Background:
- Accurate medication dosage calculation problem-solving (MDC-PS) is crucial for patient safety and effective healthcare practice.
- Existing educational approaches may not adequately bridge the gap between theoretical knowledge and practical application in MDC-PS.
- A clear model is needed to define, measure, and improve competence in MDC-PS.
Purpose of the Study:
- To advance a comprehensive competence model for medication dosage calculation problem-solving (MDC-PS).
- To illustrate the interrelationships between conceptual, calculation, and measurement competences in MDC-PS.
- To propose an educational framework integrating cognitive and functional competence for MDC-PS.
Main Methods:
- Development of an MDC-PS competence model defining conceptual, calculation, and measurement competencies.
- Exploration of PhD fieldwork challenging pedagogical approaches isolating theory from practice.
- Consideration of misconceptions theory and mathematical 'dropped stitches' in MDC-PS.
Main Results:
- The proposed MDC-PS model integrates understanding, computation, and measurement skills.
- Fieldwork suggests that abstract, practice-isolated learning can lead to conceptual errors.
- An assessment model is presented to diagnose and address flawed computational skills.
Conclusions:
- A holistic competence model is essential for effective MDC-PS education and assessment.
- Bridging the theory-practice gap requires integrating cognitive and functional competence.
- Diagnostic assessment tools are vital for identifying and correcting errors in MDC-PS.
