Biology Grade-9: Semester 2

Description

Welcome to Module 2!

This module provides a comprehensive knowledge and concept of grade 9 biology with the last three chapters. It starts from reproduction, types of reproduction, the human health, nutrition, and disease, up to ecology, ecological relationships. While online learning shares many of the fundamental design principles of effective activities, assessments, and interactions used in other learning contexts, it is worth considering the unique set of teaching and learning conditions that the online environment generates. Interactions between instructors, course content, and learners in online courses are influenced by physical and social distances, familiar and unfamiliar types of teaching technologies, and cognitive, affective, and motivational challenges as well as opportunities.

As you work through this module, you will be asked to think about the following key questions:

• Do my activities and assessments help learners develop core skills and competencies that align with my course learning outcomes?
• Have I structured my activities and assessments to help to build academic integrity?
• Are my assessments authentic, reflecting discipline-specific, real-world problems and challenges?
• Do my activities and assessments follow the principles of universal design for learning?
• Do my activities and assessments help to foster learner engagement and build community in the course?

By the end of the module, you will be able to;

• Define asexual and sexual reproductions.
