Summary
This study proposes a new instructional design for serious games (SG) in medical education, specifically for branching scenarios. The developed design demonstrated high usability among medical students, enhancing decision-making skills.
Area of Science:
- Educational Technology
- Medical Education
- Serious Games Design
Background:
- Serious Games (SG) are effective in health professions education for diagnosis and knowledge transfer.
- Branching scenarios, a type of SG, offer linear or multiple pathways for learning but require evidence of instructional design (InD) and usability.
Purpose of the Study:
- To propose an instructional design (InD) for branching scenarios in serious games.
- To evaluate the usability of these branching scenarios among undergraduate medical students.
Main Methods:
- A two-phase study was conducted, starting with literature review and expert validation (Delphi technique) for the InD.
- Five branching scenarios were developed based on the validated InD.
- Usability was assessed in a cross-sectional study with 216 undergraduate medical students using a specific instrument.
Main Results:
- A five-dimension InD for branching scenarios was successfully elaborated, guiding designers.
- Five branching scenarios were created for medical students, receiving high usability scores.
- Branching SGs with multiple options provide varied outcomes for clinical problems within a single activity.
Conclusions:
- The proposed InD for branching scenarios integrates SG theory and specific design elements (levels, checkpoints, avatars).
- The InD was tested for usability, showing positive results and potential for developing decision-making skills.
- Assessing SG usability is recommended to identify areas for improvement in future designs and platforms.

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

Albert Bandura's theory of observational learning identifies four critical processes: attention, retention, motor reproduction, and reinforcement or motivation.
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...

Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

Consider an arbitrary truss structure composed of diagonal, vertical, and horizontal members fixed to the wall. To calculate the force acting on members CB, GB, and GH, method of sections can be used. The loads and lengths of the horizontal and vertical members are known parameters, as shown in the figure.

Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...
