Debre Zeit like every other part of Ethiopia has undergone trial and tribulation to find a suitable education system. The core organization and instruction, especially reading and writing were more or less a continuation of the religious school systems like synagogue, church and Islamic school model. Below is a brief introduction of the Ethiopian education system presented by Dr. Aklilu Habte at Library of Congress.
The soul searching has been focused on building a modern education system and how to teach foreign language, mathematics, history, geography and science. While the attempt at building a modern education system began in the early 1900, it was interrupted due to the five-year occupation of Ethiopia by Italy.
Rigorous work to reform the educational system of Ethiopia re-started after the Italians were driven out. The challenge was there no home-grown professionals to advise the government on how to organize the educational system. As was indicated “efforts to create a modern mass education system intensified, but this time under the influence of education advisors from Britain and the United States.” (Source: WENR World Education News + Reviews, Education in Ethiopia (wes.org)
In line with the British influence, Ethiopia adapted English as a medium of instruction in schools starting from grade three. In fact, in grade two, we started reading the Green Primer series like “The Giraffe who went to school” and others. Then from Grade three on until grade 5, all subjects except Amharic and religious studies were provided in English.
Besides the English reading books, Arithmetic’s was taught using Highway Arithmetic books. One thing that was missing is when developing the curriculum, it was simply a copy of the British system without due consideration how mathematics was used and thought in local religious schools. For instance, Ethiopia alrady has a number system that was different from the Arabic numerals.
interestingly, there was a mathematics method developed by merchants in Ethiopia that was very advanced but was never thought in school when were young. “Ethiopian multiplication is a method of multiplying integers using only addition, doubling, and halving.”
Ethiopian multiplication – Rosetta Code is this system (methods of Ethiopian calculation) that powers today’s’ computers…… The ways they perform that calculation is almost exactly the same with the working method of a computer. Amazingly it seems centuries before the invention of computers Ethiopian traders crack the code that lies behind the modern the age”
Here is a video showing how the base two Ethiopian multiplication works:
