Study Notes

Computational Thinking

Enables analysis of complex problems and development of potential solutions.
Consists of key processes: decomposition, pattern recognition, and abstraction.

Dr. Snow's Algorithm

Utilizes a systematic approach to identify sources of disease outbreaks.
Steps include:
- Collecting data
- Identifying infected individuals
- Testing hypotheses
- Looking for patterns
- Implementing treatments

Relevance Today

Dr. Snow's methods remain applicable in modern contexts, such as public health.
Example: Use of mosquito nets for malaria prevention, though not universally adopted.

Key Concepts of Computational Thinking

Decomposition: Breaking down a complex problem into manageable parts.
Pattern Recognition: Identifying trends and regularities in data to inform solutions.
Abstraction: Focusing on essential details while ignoring irrelevant information to simplify problems.

Grading Criteria

Grade 1-3: Understand the role of decomposition in problem-solving.
