Should you still need more convincing as to the value and contribution of gesture in L2 learning and instruction, the September 2014 issue of
The Modern Language Journal (98) has two excellent, complementary articles that you should read, one by Dahl and Ludvigsen on the effect of gesture on listening comprehension and a second, by Morett, on gesture as a "cognitive aid" during speaking production and communication. (See full references below.)
The first study examines how observing gesture complements comprehension; the second then demonstrates how actually producing the gesture as you learn and then communicate with a new L2 term in the early stages of the process results in more effective acquisition, retention and recall.
The learner populations involved are quite different, as are the research methodologies, but the two studies together contribute substantially to our understanding of how and when gesture works. (You'll have to access them through your library online or shell out the usual 5-6 Vente Carmel Frap equivalents for each, of course--but it may be worth it in this case.) There is also an earlier (free, accessible online) 2012 paper by Morett, Gibbs and McWhinney,
The Role of Gesture in Second Language Learning: Communication, Acquisition, & Retention, that lays out the theoretical background for the new study as well.
One striking (but not surprising) finding of the Morett study is that using a gesture while speaking and communicating results in better acquisition than just observing the gesture being used by someone else. The other study examines the conditions under which seeing gesture performed functions best.

The bottom line: Systematic incorporation of gesture in (at least initial) L2 learning is again shown to be exceedingly effective. It must be carefully timed and linked to meaning, but the results of both studies are very persuasive. Another good example of that, of course, is
