The Science
7spell is scientifically designed, and utilizes principles based on decades of research in learning, retention, and psychology. Here is a summary of the theory and research behind 7spell's effectiveness.
Craik, F., and Tulving, E. "Depth of processing and the retention of words in episodic memory." Journal of Experimental Psychology: General, Vol 104(3) (1975): 268-294. Print and PDF. http://dx.doi.org/10.1037/0096-3445.104.3.268
In this seminal study performed at the University of Toronto, Canada, the authors performed a series of tests in which they gave the study participants a sequence of words to learn, with information related to each word as it appeared in order. They discovered that when the information provided stimulated the participant's brain to process the word on a more involved level (referred to as "deep encoding" or "degree of elaboration" in the study), that word was more effectively learned and remembered. With 7spell, the user is given a wide range of additional information about each spelling word, including the word's definition - one of the key factors in enhanced memory, according to this study - as well as usage examples, synonyms, and antonyms.

Each person is influenced by a unique set of factors related to their own status and progress towards goals, but is also affected to a greater or lesser degree by the achievements and perceived standards of the people around them. This analysis of past and current studies looks at the way people view and are motivated by individual goals as well as societal achievement (competition). The authors conclude that effective use of motivational strategies must take both into account. This is something that 7spell accomplishes by providing each user with the ability to set personal goals, earn reward points, and view their own progress tracking reports, and also to publish all of those results on public social media platforms.

In a study focusing on the influence of reward-scheme programs on behavior, the authors found that when people see visible progress towards their goals they are more likely to increase the activity required to reach those goals. The study also confirms that most people are also motivated by receiving rewards for completing specific activities, even if those rewards are not immediately transferable to actual material or monetary benefits. Status points, rewards, and real-time progress tracking are all methods used in 7spell to encourage frequent spelling practice by awarding points for the completion of exercises and activities. Because the user can access their progress charts at any time, they will always be able to see how close they are to achieving their personal spelling goals.

Instrumental learning, also called "operant conditioning," is a method by which behaviors are learned in connection with a stimulus, a reward, or both. In this research done at the University of Vermont, the authors studied the ways in which the information connected to a specific behavior is retained when the stimulus is removed, and how subsequent repetition or reward reinforces information recall and a resumption of previously learned behaviors. They conclude that there are two primary methods of reinforcing active memory and behavior: by creating a different way to test the subject's memory, and by providing the opportunity for intensive focused repetition of that stimulus-behavior response. These two methods are widely used in the 7spell activities and games to create the link between instruction and memory that is so crucial in effective spelling learning on the student's part.

In this study comparing long-term and short-term memory, the study authors tested the neural activity of participants as they memorized a set of images. Half of the study participants used massed learning techniques, in which each new image was presented multiple times in a row; the other half were given the images in a spaced repetition mode, where the images were shown in alternating order. Although each participant saw each image the same number of times, the people in the spaced-repetition exercise were able to accurately remember more images, and for a longer period of time. Repetition is a key technique in learning spelling, and 7spell incorporates spaced repetition in two ways. First, the system uses randomized selection of spelling words from the user's current list to populate the activities and exercises, ensuring an interval between word reviews. Second, the system's Word Discover feature provides pop-up instant review of the words on that list, again in random order. By providing users with multiple opportunities throughout the day to read and review their words, 7spell provides all of the benefits of the spaced repetition methodology in its spelling instruction.

Spaced repetition is a memory training tool that relies on frequent and consistent review of information; mnemonics is a memory technique that involves multiple ways of looking at that information, such as the incorporation of images or story lines. Researchers at Carnegie Mellon University focused on the combination of spaced repetition and mnemonics in evaluating how best to train people to remember specific pieces of information: computer passwords. They found that by combining the two methodologies, the results in both ease of learning and retention were increased. 7spell uses each method separately and together to help users learn and remember new spelling words by using the same words in multiple exercises, presenting spelling words in a variety of formats, and encouraging users to add information related to each word to make a personal connection that helps them to remember that word and its correct spelling.
At the end of this month, the 2012 Scripps National Spelling Bee will be broadcast on national television in the United States and around the world, and thousands of people will watch 278 young students compete for the title of champion speller. The competitors come from all over the United States, from China and Korea, from Japan and Jamaica, and all have been focused on learning the quirks and intricacies of English spelling. Some have been studying spelling for six years – and one of the competitors is only six years old! Lori Anne Madison is the youngest speller on record to compete in the Scripps National Spelling Bee. This second-grade student from Virginia is also a gold-medal competitor in science and robotics competitions, and takes part in swimming meets as well. You might wonder how she finds the time to study her spelling with such a busy schedule, but she says that she reads a lot, and that she loves to “find new interesting words in the dictionary.”
If you’re a parent of a young child, and want to encourage them to develop their spelling skills, take a hint from Lori Anne Madison, and start by encouraging your child to read. Many studies have proven that the more children read, the better they spell. Help your child learn to love reading, first by reading aloud to them and then later reading with them, or helping them pick out a book at the library. The benefits of reading include better spelling skills and more success at school even in classes other than English.
Children like to play games, so make it a game to find new words to learn. As part of learning a new word, draw pictures, tell a story using the word, and practice the word’s spelling. You can also make spelling quizzes into fun activities if you award points and prizes, or have two or more children compete against each other.
Incorporate spelling into as many aspects of the child’s life as you can, and you’ll find that they naturally pick up good spelling skills. And be sure to tune in to the Scripps Spelling Bee and cheer on the competitors – it’s a good way to learn new words, too!
Have your say!
