Course Description
Welcome to Module 1!
This module covers fundamental concepts and principles of acid-base equilibria and electrochemistry. It provides a comprehensive understanding of various acid-base theories, the behavior of weak acids and bases, and the principles of redox reactions and electrolysis. By the end of this module, students will be able to describe and apply these concepts in various chemical contexts and practical applications. While this 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 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?
