Here is an example of what my virtual flashcards look like (very simple, nothing fancy):
Virtual Flashcards - Adjectives that Describe Things
For each set of vocabulary, I make two sets of virtual flashcards; one where the picture appears first, followed by the word (when clicked), and one where the word appears first, followed by the picture (when clicked).
This allows me to focus on recognizing words during the first week of instruction. I display the word and call on a student to tell me what it means. As the week goes on, you can easily measure the progress as the students take way less time to make it through all 20 slides. Their responses become more automatic and they do not have to use a reference sheet/vocabulary list to find definitions.
During the second week of instruction, I focus on getting students to produce these words. I display the pictures (which students are now familiar with after seeing them during the first week) and call on a student to tell me the Spanish word. I listen for pronunciation and target common mistakes. I can also pull out my dry erase boards and ask for written responses from the entire class. At the end of the second week, we say the words together as the pictures appear. Again, you can tell the progress based on how long it takes students to come up with the answer. Sometimes we even make a game out of it by timing ourselves Monday, Wednesday, and Friday and seeing how much faster we have gotten.
Virtual Flashcards, once created, are easy to share with students and parents. You can upload them to a school website or e-mail them. When parents or students ask what students can do at home to practice, I always send them a copy of the current flashcards. I also no longer have to write out a million sentence strips only to lose them (or have them crumpled beyond repair) the next year. Some of the teachers at my school require the students to make their own flashcards for homework, which they do, never to pick them up again. This way you KNOW your students are reviewing.
Once students are familiar with the images you use in the flashcards, you can use these same images on worksheets, tests, for storytelling, classroom games, etc. The use of pictures reduces the reliance on English, which on it's own will improve their acquisition of the new language.
