In this study we researched varying aspects of using flashcards to increase vocabulary, these aspects include method variations, as well as variations to the flashcards themselves. Through this text it is conveyed that vocabulary is important for communication. The aim of this research is to reflect upon the various flashcards variances and understand their effects upon vocabulary teaching. To research both writers searched for relevant articles together, these articles were agreed upon together. Each researcher read and summerized half of the articles each. Afterwards, the other researcher read the same article and inspected the written summaries. The results of the various research papers generally agreed with theories of learning. Multiple different learning theories were used as basis for this research, and the findings of the research articles are overall in agreement with these theories. The different drill methods, altering the flashcards themselves and the introduction of digital flashcards were found to be in agreement with the relevant learning theories. The different flashcard alternatives were found to have positive results, however these positive results were in different aspects. Some results found the students had larger vocabulary, some other results found the students had longer retention of the vocabulary learnt, and some had increased motivation.
