There are many techniques that can be used to teach vocabulary. The approach in Français interactif gives students word level practice before requiring them to negotiate meaning of richly contextualized samples of vocabulary.
Please download the template for Préparation du vocabulaire from Chapter 2 under the Liste de vocabulaire. This sequence of exercises, a "first pass" is primarily a decontextualized treatment of the vocabulary, as it requires learners to study and manipulate words in isolation. They practice pronunciation, identify cognates and word families, and relate words to create associations.
Students end with Chassez l'intrus (Find the word which doesn't belong), an activity which requires them to make connections across words, thereby contextualizing the individual lexical items.
Students do these exercises as homework at the beginning of each chapter. This video demonstrates a typical classroom followup. Please note that this is Chapter 2 of first-semester French.
