Since the program uses the “discovery” method of language learning for the learner, there is no initial input to teach the learner vocabulary or other language aspects in context. This presumes quite a lot on the part of the learner who must then know or find a way to record and practice grammar and vocabulary of the language. Written and listening examples in native Spanish speaker male and female voices, written and oral drills, and exercises are very well done but even at level 3 the program still lacks clear instructions on completing exercises for the Spanish language learner.
The lower level Spanish program materials may be the same for both Latin American Spanish and Spanish (Castellano) from Spain as some vocabulary and usage drills seem to indicate. Ultimately, this will be less of a problem, but if the Spanish language learner doesn’t have any strict reinforcement of Latin American Spanish, there could be some problems with their listening comprehension since different expressions and vocabulary are used in the program which are NOT typical of Latin American Spanish but are much more likely to be heard or spoken in Spain or Europe.
In reference to time, the Latin American Spanish program uses the expressions “retaso a horario” and “menos quince a la hora”, which aren’t typically heard in much of Latin America. More commonly used are "faltan quince para las tres" or "faltan cinco para la una" (or whatever the hour will be). Spoken examples and drills are clear and understandable, but they are also spoken a bit more slowly than in a normal conversational speed. Ultimately, this can cause listening comprehension problems for learners who develop a “practiced ear” for the slower conversational speed used in the program. Frequently used, alternative words are not illustrated in the program. For example, the word “derecho” is always used to mean straight ahead or forward and is quite commonly used, but the word “recto” is also frequently used in some Latin American regions, like in Panama and parts of Colombia.
