Many foundational concepts in biology are notoriously difficult to teach. The challenge grows tougher when you add the need to align with the Next Generation Science Standards (NGSS). This book makes your job easier by opening your mind to fresh and effective approaches for today's high school classrooms. Hard-to-Teach Biology Concepts provides an Instructional Planning Framework that helps you understand students' learning needs, incorporate appropriate teaching strategies, and interpret the framework and teaching tools through the lens of NGSS. Contributing authors show how they use the framework to teach four NGSS disciplinary core ideas: growth and development of organisms, ecosystems, heredity, and biological evolution. Although the teaching models are specific and illuminating, the book doesn't dictate what's right for you. Veteran teachers and those new to the classroom can use the framework to develop students' conceptual understanding based on what works best for student and teacher.
