The first part of this magnitude will examine alternative powered circuits, circuits which display diverse combinations of resistance, inductance and capacity. The second part will examine the momentum of charged particles in both electric and magnetic fields. We will describe and explain J.J. Thompson’s experiment, the Hall effect and the principle of accelerating particles such as cyclotrons and synchrotrons. Next we will study the electromagnetic induction phenomenon, Lenz’s law, auto- and mutual induction phenomena and their resulting applications. The third section will describe and analyze the properties of the three classes of magnetic substances: the paramagnetic, the ferromagnetic and the diamagnetic. The last part of the module explains the four fundamental equations (Maxwell’s equations) which underlie electromagnetism and examine electromagnetic waves, their polarization and the energy they transport.

This is a four unit module. The first two units cover the basic concepts of the differential and integral calcualus of functions of a single variable. The third unit is devoted to sequences of real numbers and infinite series of both real numbers and of some special functions. The fourth unit is on the differential and integral calculus of functions of several variables. Starting with the definitions of the basic concepts of limit and continuity of functions of a single variable the module proceeds to introduce the notions of differentiation and integration, covering both methods and applications. Definitions of convergence for sequences and infinite series are given. Tests for convergence of infinite series are presented, including the concepts of interval and radius of convergence of a power series. Partial derivatives of functions of several variables are introduced and used in formulating Taylor’s theorem and finding relative extreme values.

The module consists of 5 units, each with at least 4 learning activities. First you will be introduced to ecology by defining its various branches and terminology. You will then learn how organisms are organised into populations and communities and factors governing their change over time. Organisms interact with one another in ways that affect their populations we will therefore study the various types of relationships between populations and their implications.

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.

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.

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.

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 is a first degree course in Mechanics. The module starts with a treatment of vectors and vectors calculus and attempts to explain all the topics in mechanics from this basis. It is hoped that the students enrolling for this course will acquaint themselves with the basic notions of force and the resultant motion of its application. Four areas of mechanics: Statics, Dynamics, Kinetics and Kinematics of particles and rigid bodies have been treated in this module. The student is strongly advised to consult Physics sources on Mechanics in conjunction with this module for practical examples which are mathematically modelled in the module.

This Module is a study of organisms that can not be seen with the unaided eye unless with the help of a microscope. They are referred to as microorganisms. More commonly they are called microbes. These are bacteria, viruses, protozoa and fungi. Although viruses are strictly not organisms, they too will be discussed under the same title for convenience. Mycology which is the study of fungi includes some groups like the mushrooms with macroscopic fruiting structures, which appear seasonally above the ground. The study of microbes is called microbiology.

This module consists of three units: Unit 1: Descriptive Statistics and Probability Distributions - Descriptive statistics in unit one is developed either as an extension of secondary mathematics or as an introduction to first time learners of statistics. It introduces the measures of dispersion in statistics. The unit also introduces the concept of probability and the theoretical treatment of probability. Unit 2: Random variables and Test Distributions - This unit requires Unit 1 as a prerequisite. It develops from the moment and moment generating functions, Markov and Chebychev inequalities, special univariate distributions, bivariate probability distributions and analyses conditional probabilities. The unit gives insights into the analysis of correlation coefficients and distribution functions of random variables such as the Chi-square, t and F. Unit 3: Probability Theory - This unit builds up from unit 2. It analyses probability using indicator functions. It introduces Bonferoni inequality random vectors, generating functions, characteristic functions and statistical independence random samples. It develops further the concepts of functions of several random variables and independence of X and S2 in normal samples order statistics. The unit summarises with the treatment of convergence and limit theorems.

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.
