Challenges facing education in South Africa outh Africa has a high-cost‚ low-performance education system that does not compare favourably with education systems in other African countries‚ or in similar developing economies. There is a multitude of well-publicised problems‚ including a shortage of teachers‚ underqualified teachers and poor teacher performance. In the classroom‚ this results in poor learner standards and results‚ a lack of classroom discipline and is exacerbated by insufficient resources

P3 & P4: Communication barriers and how to overcome them Type of barrier Why this could be a barrier Unmet language needs or preferences Unmet language needs or preferences is a communication barrier because if you don’t speak the same language as the service user you won’t be able to understand what the other person is saying and the other person won’t be able to understand you‚ so there isn’t any communication being made. Linking this to the case study ‚ where the care worker ‘‘Joanne’

the introduction of contaminants into a natural environment that causes instability‚ disorder‚ harm or discomfort to the ecosystem i.e. physical systems or living organisms.[1] Pollution can take the form of chemical substances or energy‚ such as noise‚ heat‚ or light. Pollutants‚ the elements of pollution‚ can be foreign substances or energies‚ or naturally occurring; when naturally occurring‚ they are considered contaminants when they exceed natural levels. The major forms of pollution are listed

additive noise is characteristic of almost all communication systems. This additive noise typically arises from thermal noise generated by random motion of electrons in the conductors comprising the receiver. In a communication system the thermal noise having the greatest effect on system performance is generated at and before the first stage of amplification. This point in a communication system is where the desired signal takes the lowest power level and consequently the thermal noise has the

Prof. BERESFORD TALK ABOUT THE PROBLEMS OF POLUTION (Tape script‚ slightly abridged) Pollution is today‚ probably‚ the greatest problem that faces mankind. There is a saying in English that it is an ill bird that fouls its own nest. And human beings are‚ collectively speaking‚ fouling their nest at the increasing rate. It is an alarming picture. We are polluting the air‚ which we need to breathe‚ the earth from which we derive all our food‚ and the waters from which wе‚ of course‚ derive the

Describe the barriers of effective communication. Introduction: If an individual (Sender) sends a message and the receiver interprets it in the same way as the sender had intended to express‚the process of communication is said to be complete. But it is not always so. Certain barriers in communication affect the clarity‚ accuracy and effectiveness of the message. The barriers could be related to the communication system‚ mechanical devices being used‚ language or symbols being used

Besides the blowing of horns‚ rumbling of factories and noises from the loudspeakers and vehicular movements are causing noise pollution as well. The pollution has been an important cause of various diseases like high blood pressure‚ asthma‚ skin problem and respiratory disorders. Migration is also major cause of pollution. Every day a large
