Abstract: A list of 20 four-word sentences was memorized by 40 first grade junior middle school pupils. The results showed:1. The methods of memorization used by the pupils are: grouping the materials by meaning, grouping into quantitatively equal portions, using the first word of a sentence as hint, grouping by rhyming the materials. Some subjects learned the sentences one by one by rote learning.2. The efficiency of different methods of memorization is conditioned by the nature of the materials and the learning task. If all parts of the material are learned to approximately the same degree, the materials are better retained.3. The method of memorization adopted by the pupils is dependent upon their understanding of the materials. Those understood the materials equally well may, however, use different methods for memorization.4. The different methods of memorization reveal in a certain degree the different processes of memorizing the materials.
