Tesoros (Treasures) is an exciting and innovative first year media-based Spanish program that addresses the growing faculty and student interest in multimedia educational products. The Tesoros program is one in which the core course content (including vocabulary and grammar presentation and practice) is delivered on an interactive 5 CD-ROM set. An animated mystery story serves to engage and motivate students in a medium that is captivating, pedagogically sound, and fun. The CD-ROM set, which is available separately from the textbook, can be used as a multimedia supplement to any beginning or intermediate level Spanish textbook. The Tesoros textbook complements the CD-ROM set by providing activities that support the mystery storyline, additional vocabulary and grammar practice, and cultural and literary readings.
