Abstract:

Researchers have suggested that the input-enhancement hypothesis (e.g., Chapelle, 1998) and mind-centered input-based theories (e.g., Collentine, 1998) might be consulted for the design of multimedia CALL. The input-enhancement hypothesis, processing instruction theory, and the nature of Spanish preterite and imperfect were examined in this light in order to determine how the input-based hypothesis and theory could inform the input-enhancement methods and techniques needed for the design of a computer application focusing on the instruction of the targeted structures. Despite having considered the above mentioned hypothesis and theory, to derive potentially effective input-enhancement techniques, the application would have to take the following into account: the student's learning problems observed during classroom teaching, the shortcomings of the language models included in textbooks, the drawbacks of current grammar rules, our incomplete knowledge of the uses of the Spanish preterite/imperfect. Consequently, this mini input-enhancement application draws insights from the following areas to guide its design: the input-enhancement hypothesis, processing instruction theory, the author's investigation in the uses of the Spanish preterite/imperfect, the benefits of using videos in language instruction, and the concept of data-driven learning as exemplified by concordances. The author concludes by proposing that to create a potentially effective input application for grammar instruction, CALL designers need to consult other relevant areas in addition to considering SLA theory.
