Module Description

This module provides a comprehensive knowledge and concept of grade 11 physics. It starts from heat conduction and calorimetry, the concept of heat, heat transfer mechanisms, heat capacity and specific heat capacity ,thermal expansion, change of phase, calorimetry , electrostatics and electric circuit , Columbo’s law , electric field , electric potential, electric current, current density, resistance, conductivity, resistivity and drift velocity, capacitors, capacitances, dielectric, electric circuit in our surrounding, Nuclear physics ,Atoms ,Radioactivity ,use of nuclear radiation, Nuclear reactions and energy production, Nuclear safety, 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:

• 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 learners develop core skills and competencies that align with my course learning outcomes?
• Do my activities and assessments help to foster learner engagement and build community in the course?
