Rationale
This unit aims to make algebra more relevant and engaging for high school students. Algebra is often viewed as abstract and disconnected from students' everyday lives, leading to a lack of motivation and interest. By demonstrating the practical applications of algebra in understanding real-world biological phenomena, such as lactose tolerance, this unit aims to bridge that gap and spark students' interest in the subject.
Moreover, this unit aims to inspire students and show them the importance of mathematics in understanding and solving real-world problems by connecting algebra to a fascinating topic like evolutionary medicine. This approach can foster a love for learning and motivate students to engage more deeply with their studies.
Relevance to Students' Lives: Many students may have personally heard of or experienced lactose intolerance. By exploring lactose tolerance's genetic and evolutionary basis, students can connect algebraic concepts to something tangible and relevant to their lives. This personal connection can enhance their interest and engagement in the subject, making them feel more connected. Furthermore, the unit includes an initial anonymous survey to determine what percentage of the students are lactose intolerant, making the unit more appealing as it directly relates to them.
Interdisciplinary Learning: This unit exemplifies the benefits of interdisciplinary learning by integrating algebra with biology. Students gain a deeper understanding of both subjects by examining how mathematical models can be used to study genetic traits. This holistic approach enriches their knowledge and encourages them to see the interconnectedness of different fields of study.
Preparation for Standardized Assessments: Integrating mathematics and science in this unit aligns with educational standards and prepares students for Science Standards of Learning (SOLs) assessments. By developing their analytical, problem-solving, and critical thinking skills, students will be better equipped to perform well on these assessments. The unit provides a comprehensive learning experience that reinforces key concepts in algebra and biology, giving students a sense of readiness for their assessments.
Development of Critical Skills: Students will develop essential skills that are valuable in various academic and career paths by applying linear models and data analysis. These skills include data interpretation and constructing and testing hypotheses as various linear models. Students will also enhance their mathematical proficiency and scientific literacy.
Real-World Applications: Evolutionary medicine is a rapidly growing field that applies evolutionary principles to understand health and disease. By exploring the genetic basis of lactose tolerance, students can appreciate the practical applications of algebra in scientific research and medicine. This understanding can inspire them to pursue further studies or careers in STEM fields.
