Animal Diversity
Conditions of Use:
Remix and Share
Rating

The lessons presented in this module on animal diversity are based on the social constructivist theory of learning. Learners construct their own understanding and develop their own skills, both individually and as part of a peer group. The activities presented here will help you, but a large part of the responsibility rests on you, in the aim of fostering learner empowerment.

Evolution Biology
Conditions of Use:

The course emphasises variation among life forms as the fundamental basis for evolution arising from environmental factors and mutations that act on the genes, which are the basic units for inheritance. When these genetic changes in a population are constantly acted upon by a variety of environmental pressures, organisms with better-suited genes to the changing environment survive, reproduce and multiply. These organisms are favoured by the process of natural selection, which continues to act on the population, over successive generations, until a population that at one time could interbreed not longer can do so. This leads to a population split that gets divided into two or more species.

Geometrical Optics and Physical Optics
Conditions of Use:

Rating

In this module, the concept of light’s behavior when reflected from the same medium or at the interface between two different media will be treated. The construction of images obtained through optical systems and different types of lenses will be discussed. Certain optical systems will be presented in this module: the eye, a magnifying glass, a microscope, a telescope, a camera, along with the way they work by calculating focal lengths, magnification and vergency (optical power). The module explains the comprehension and correction of vision problems: farsightedness, nearsightedness. The next step will be to explain essential wave-related concepts, along with the way they interact. The observation that the pitch of sound from a siren changes when the source or receiver or both moves will be elucidated. The concept of phase will allow the understanding of phenomena such as interference or diffraction when two apparently identical phenomena are superimposed.

Geometry
Conditions of Use:

The Module on Geometry starts by looking at the historical development of knowledge that the humankind gather along centuries and became later, about 300 BC, the mathematical subject called “Euclidian Geometry” because of the grate work of Euclid. The inductive-deductive reasoning which characterizes this subject will be developed through investigation of your own conjectures on geometric objects and properties. You will explore geometry by using basic mechanical instruments (compass and straightedge) and computer software. As you progress you will treat the Euclidian geometry using a referential system to locate points. The orthogonal Cartesian system of coordinates that you already know from secondary school is the most common referential system you will use in both two and three dimensions. You will also learn some other systems of coordinates that will empower you to do research in geometry and in other mathematical modules as well. Going deeper in analysing the axiomatic construction of Euclidean geometry you will learn new geometrical structures, generally designated as Non-Euclidian geometry. So, summarily speaking, this Module is about Euclidean geometry treated in both syntactical and analytical ways and encloses an introduction to Non-Euclidean Geometry, handled synthetically only.

Introduction to Guidance and Counseling
Conditions of Use:

This Module Four: An Introduction to Guidance and Counseling has been written specifically for you as a teacher who is undergoing training to become an effective and useful person to students, teachers, and school administrators and of course to the larger community around the school. There are four units in the module. In each unit, statements of General and Specific objectives have been given. These statements of objectives are there to help you remain in focus, and also in making sure that the necessary knowledge, skills and attitudes are acquired by you within the period of the training. There are also activities that have been included as part and parcel of the required things you are expected to do or meet. It is important that you do not only find time, but also ensure that they are done. The references that have been included in the module are things you must make all efforts to read them. Access to computer is a must for you, because most of the readings can only be accessed through the internet.

Managing a School's Educational Resources
Conditions of Use:

Apart from teaching, as a teacher you can also assume other positions of responsibility: Principal, Headmaster, Headmistress, Vice Principal, and so on. Each actor has a specific role in the school system, but all activities within the school system are interrelated. This module answers the following questions: What are the different components of a school system, and how do they interrelate functionally and structurally? What is the concept of the Principals role and how is it exercised? How can you create a school climate that nurtures human and intellectual development and prevent failures? How can you manage relationships between the various school actors? How can you manage, use and develop school resources? How can the schools human resources manage the available resources for which they are responsible?

This module deals with the mathematical elements essential to understanding physics courses, namely the study of real functions, derivation and integration of a function with one and several real variables, the development of a function, some elements of numerical calculations and, finally, solving a system of linear equations. Learning activities of different difficulty levels are developed with formal assess- ments. Moreover, online word and useful links enable students to study certain topics in detail.

This module develops upon the concepts introduced in the module Physical chemistry 1, which focused on kinetic molecular theory, thermodynamics and chemical kinetics. It covers the study of solutions and colloids, phase equilibrium, electrochemistry and nuclear chemistry. In solutions, we examine essentially the behaviour of homogenous mixtures involving pure substances.

Quantum Mechanics

The module describes the experimental findings that lead to a new concept and a new scientific attitude towards physical phenomena at the microscopic level. In addition, the module describes the formal terminology based on assumptions derived from these experimental observations, such as Schrödinger's wave mechanics and the fundamental principles of quantum mechanics. Examples of applications (such as the study of a related one-dimensional study of a system of two quantum states, and the study of the hydrogen atom) can aid in supporting the results of abstract ideas which bring about the various formal theories of quantum mechanics.

This module covers introductory topics that are fundamental to analytical chemistry; the branch of chemistry that deals with qualitative and quantitative aspects of chemical analysis. In this module, we shall examine the quantitative aspects of reactions in aqueous solution. These quantitative dimensions are sometimes referred to as solution stoichiometry.
