Simple, effective Spanish vocabulary learning:

Flash cards are one of the best tools for memorizing information. This application provides a set of flash cards for memorizing vocabulary. These electronic flash cards are used just like paper or cardboard cards. The English word is displayed on one side, and the Spanish word is displayed on the other. You can hear the pronunciation of each word. You can go through the cards, and see how many words you get right. Once you feel confident in your knowledge, you can test yourself by taking the Quiz.
You can configure your learning experience by selecting the number of cards, category, and order of presentation.

Other great tools for learning and memorizing vocabularies are word games. The word games included in this application are Concentration and Mix & Match. You can use these games to improve your memory and word association skills.

Concentration is an educational game in which some cards are laid face down on a surface and two cards are flipped face up over each turn.
The object of the game is to turn over pairs of matching cards. A matching pair is one where an English word matches a corresponding Spanish word. When a matched pair is selected both cards remain turned over.
The game ends when the last pair has been turned. The score is determined by the amount of time required to find all matching pairs.

In Mix & Match, a player matches English words to corresponding Spanish words.
Words can be dragged around the screen. Any two words side-by-side are considered “matched”
The game ends when all words have been matched correctly.
The time you take to match all words determines your score.

Alumno comes with a lexicon of over 850 commonly used words. These words can be organized into “categories”, or user-defined groups, to make the learning process more focused and effective. There is also the option of adding your own words, as many as you want. The lexicon can be searched, providing a simple, handy English-Spanish/Spanish-English dictionary. Check out the help pages included with the application to see how vocabulary items can be added, edited and deleted.
