• Keywords: Educational Games, Process Reflection, Game Visualization, Open Player Model (OPM), Parallel Programming, User Experience, Data Transparency, Serious Games

Research Background and Issues

• Identified Problems or Challenges:

  1. Educational games are considered effective educational tools, but there is a research gap in how data visualization can help students reflect on their learning process and analyze peer strategies.
  2. Current data visualization systems are mostly designed for game designers or analysts, with limited research on player-friendly visualization.
  3. Traditional Open Learner Models (OLM) primarily focus on academic progress and fail to address dynamic processes and strategy data in serious games.

• Why This Issue Is Important: The increasing adoption of educational games in teaching environments highlights the need for effective communication of process data and strategy information to enhance learning outcomes. By leveraging effective visualization systems, students can better understand their own and their peers' game strategies, fostering reflective insights to improve learning performance.

• Research Motivation and Related Work: Building on research in the OLM domain, this paper introduces the concept of Open Player Model (OPM) to address the limitations of traditional learning models in handling complex game data. It also employs novel UX design methods to meet the practical needs of students and educators.

Solution

• Proposed Method or Solution: This study proposes a new OPM system capable of visualizing complex player data in serious games. The system is based on spatial partitioning and domain knowledge mapping, focusing on abstracting and presenting player behavior data.

• Innovative Aspects of the Solution:

  1. Development of a model that maps the spatial logic of serious games to academic concepts.
  2. Provision of domain-based error annotations and recommendation mechanisms to help players identify optimization strategies and improve decision-making.
  3. The system balances the need for an overview (high-level data aggregation) and detailed insights (specific content on demand).

• Implementation Steps:

  1. Requirement Collection: Conduct interviews and observations with teachers and students in the parallel programming domain to summarize system requirements.
  2. Design and Development: Develop partition abstraction algorithms and similarity judgment algorithms to identify key learning points and optimization opportunities.
  3. Evaluation: Apply the OPM system in the educational game Parallel, validating user experience and comprehension through game testing and student interviews.

• Key Technologies:

  1. Spatial Partitioning Algorithm: Divides the game space into regions with distinct semantics.
  2. Knowledge State Labeling: Annotates player behaviors based on domain knowledge to indicate correctness.
  3. Similarity Calculation Algorithm: Matches player states with high-learning-opportunity states in the community using cosine distance.

Research Outcomes

• Specific Results:

  1. Successfully developed a visualization system that helps students analyze learning opportunities in serious games.
  2. Delivered an efficient human-computer interaction design that enables players to compare their performance with peers and improve learning strategies through recommendations and reflective prompts.

• Advantages Over Existing Solutions:

  1. First to integrate complex player data in serious games with the OLM domain, addressing a gap in the field.
  2. Considers player needs and UX design principles, achieving an intuitive and information-rich visualization interface.
  3. Supports process-level learning reflection rather than solely focusing on outcome-oriented academic progress visualization.

• Experimental or Evaluation Results:

  1. Players can better understand their gameplay process and peer strategies through the OPM system.
  2. Players flexibly apply recommended learning opportunities and form optimized solutions through simulation and comparison.
  3. Players generally express positive attitudes toward sharing personal game data, supporting community-driven learning models.

• Limitations and Future Directions:

  1. Current algorithms may not be applicable to all types of serious games, especially those not driven by spatial logic.
  2. The linear event display in the game may not fully accommodate multi-threaded or concurrent event scenarios.
  3. The study sample lacks gender diversity; future research should expand participant diversity to ensure generalizability of findings.
  4. Further longitudinal studies are needed to explore the depth of reflection and long-term learning outcomes.
