Teaching Verbs Of Motion In A Task-Based Russian As A Foreign Language (Rfl) Course, Joan Castellví, Elena Markina

Russian Language Journal

The paper focuses on one of the most complex topics in Russian as a Foreign Language (RFL) instruction: verbs of motion (VoM). We introduce an innovative approach to teaching these verbs, grounded in Task-Based Language Teaching (TBLT), and contrast it with the traditional approach that follows the Presentation-Practice-Production (PPP) framework, which has dominated the field until now. By analyzing a sample of widely used textbooks specializing in VoM, we show that introducing the VoM system—specifically, the sequence in which the verbs are presented—follows the PPP design and is primarily grammar-oriented. This approach is based on the concept of “directionality,” which …

Do Your Abc: Teaching Tense And Aspect With Verbs Of Motion, Irina Six

Russian Language Journal

This paper examines the continued application of a content-based approach initially developed for teaching Russian verbs of motion (VoM) at the novice level (Six). It begins by introducing the ABC principle, a method that presents prefixed and unprefixed VoM together in their most typical contexts, rather than separately. The ABC principle ("A+B+C=D", as in поплыл + плыл + приплыл = плавал) helps visualize a three-leg journey and introduces students to two distinct sets of stems: Directional stems for A, B, and C verbs, and Non-directional stems for D verbs.

The paper then explores extending the ABC principle to intermediate-level …
