As a representative of
the complex approach of program design, the four-component model (4K model) assumes the creation of a program based on real-life situations that the student students currently face or will encounter after the program. A distinctive feature of the 4K model is the use of such situations in their whole entirety, avoiding their division into parts if possible.
Consider teaching car driving: according to the 4k model, the program should immerse students in simulations that mimic the entire driving experience—from opening the car door to navigating from point A to point B, and finally, closing the door upon arrival. These simulations occur under conditions that mimic real-life as closely as possible yet remain manageable for the learner at the beginning of the program and become real and difficult at the end. The 4K model critiques methods that dissect driving into tasks which focus on isolated skills, like parking or straight-line driving without traffic signs, as these do not prepare students for real-world driving complexities. While the 4K model accommodates such "isolated skills" tasks as supplementary, it warns against programs built exclusively around such isolated tasks. Students trained in such a fragmented fashion may struggle to integrate these skills in real-life settings.
The main goal of this approach is to facilitate students' effective transfer of knowledge and skills beyond the confines of the educational program. Additionally, the model cares about students' cognitive load to prevent students from feeling overwhelmed. To this end, the model advocates for a curriculum foundation comprising four key components to enable both learning and its transfer: (1) learning tasks, which are the simulations of real-world problems, (2) supportive and (3) procedural information, and (4) part-time practice.
Thus, the 4K model aims to help students learn how to coordinate the knowledge, skills and competencies acquired in the educational environment in a real environment outside the program. In addition, the 4K model takes care of the cognitive load of students, trying not to overload them. Considering students' cognitive load when you train them in simulations that represent the whole real situation is especially important. According to the 4K model, the following four components should form the basis of the program so that students learn how to cope with real problems: (1) a series of simulations, (2) supporting and (3) procedural information, and (4) partial practice.
