Teaching and eLearning Selftest-wiki

A multiple choice selftest-wiki where the questions and internet links are input by the Users. A collaborative activity that benefits educators and students alike. The software accepts new questions and can build into a valuable teaching and learning resource for any subject.

The software can also act as a proctor for examinations and includes reports of examination results in summary format suitable for class lists or in detailed format suitable for individual students. The selftest-wiki is also applicable to commercial and other endeavours apart from it's usefulness to mainstream educators and students.

The Selftester program has been re-written in PHP to enable it to be used on the internet. The Analyser program that can be used to process and analyse a Test's questions and Student results, as well as, produce reports, is still Windows PC based.

Albedo Offset Calculators

Low albedo, unreflective surfaces, absorb sunlight and get hot. High albedo, solar reflective, surfaces reflect sunlight and stay cool.


Choosing high albedo or solar reflective materials for roads, roofs and footpaths, as well as, the walls of buildings, can help mitigate climate change both locally and globally.

The albedo offset calculators program calculates the global warming offset that increasing the albedo of urban areas globally, or for square meters of a local area such as a roof, or a city, would provide as an offset to global warming. The results are given in tonnes of CO2e, watts, Dollars and also as a percentage of current global warming.

When this program was first written global warming was 0.7 degrees Centigrade. It is over 1.0 degree Centigrade and increasing at an accelerating rate. However, the program enables one to configure the current value.

Albedo Offset Calculators (Windows PC)

Download "Albedov81.zip" - It contains the Albedo Offset Calculators installation program - "Albedov81.exe"
Albedov81.zip
Albedo Offset Calculators vers 8.1

Try the online local albedo offset calculator. It has a limit in area of 1 million square meters and gives the kilowatts of offset to global warming, as well as, the tonnes of CO2e and a dollar value for the offset. Meters can also be regarded as square kilometers and the calculator's results then multiplied by 1 million. There are a million square meters in a square kilometer.
