This pack contains three chemistry programs on cassette and a booklet. The booklet is divided into three sections: Teachers' Guide, Students' Notes and Technical Documentation. loading instructions appear on the inside front cover of this pack and all other instructions are contained in the booklet.

IR - This program provides an introduction to infra-red spectroscopy by presenting the spectra of some very simple organic compounds. The student is to work out the number of atoms of each element contained in one molecule of compound.

PH - This is a four part simulation of titration of acids against bases. part 1 gives a basic review together with a graph plotting facility. Part 2 is a test on elementary theory and Part 3 is a test on the mathematical theory on pH curves. Part 4 sets graded random problems with model answers.

ORGANAL - This is a simulation of an organic functional group analysis. By doing tests with selected reagents, the student can identify the compund. Functional group reactions are summarised in the Basic Review to which one can refer during the analysis.

Gruneberg LINKWORD language courses are unique in using a number of established principals of memory to make language learning quicker, easier and more enjoyable than by conventional methods. An independant assessment of a course run in a major international travel company found that executives learned in 12 hours what normally took 40 hours to learn.

The pack contains a program cassette, an audio cassette, and an instruction booklet, so combining computer-aided instructions with audio practice. As you use the programs you will follow a planned learning sequence, which continually develops your knowledge.

The course teaches a vocabulary of about 400 words, covering topics such as restaurants, food, numbers, business, travelling, emergencies, the car, the beach, furniture, colours, clothes, the family, telling the time, places, people, and the calender. The course starts with a number of animal words.

You do not need a gift for languages to use this course. You will be amazed at how quickly and effortlessly you learn, without hours of homework, simply by reading what is on the screen and working with your microcomputer.

This pack contains three programs on cassette.

Put in the Signs provides practice in addition, subtraction, multiplication and division. Each exercise presents the pupil with incomplete sums into which they must insert the sign which will make the calculation correct. If two incorrect attempts are made, the program provides the correct answer.

The two Missing Signs programs present addition and subtraction, or multiplication and division equasions which have the balancing sign missing. The child must calculate both sides of the equasion and decide wether the missing sign is greater than (i.e. >) or less than (i.e. <) or equal to (i.e. =). The equasions contain one and two digit numbers.

All three programs offer a high degree of user control over the exercises presented to the child. The "Teachers' Notes" which appear at the beggining of each program give the user the opportunity to set the layout, difficulty, content and timing of the exercise before the child begins. Once these parameters are set, the program can be used by up to 20 children and their results will be stored for later recall.

It is a technique which combines an audio voice-track with computer software to provide a unique audio-visual presentation. Children (and adults!) can be left to operate the computer on their own. They simply follow the clear instructions given by the presenter and the software.

The presentations offer an absorbing mix of explanation, demonstration and active participation at the keyboard. They introduce various features of the computer, explain certain computer terms and tell something of the history of computers and computing. Though primarily intended for children in the 9-12 age range, the presentations will nevertheless find an audience amongst all those who would like a simple, easy-to-understand guide to computers and computing.

The pack contains two voice-track cassettes and two software cassettes. You will need two cassette recorders in order to operate the presentations successfully. (However, full instructions are provided on how to transfer the computer software to disc).
