The involvement load hypothesis (ILH) was designed to predict the effectiveness of instructional tasks for incidental L2 vocabulary learning. In this meta-analysis we examined 398 effect sizes from 42 empirical studies (N = 4,628) to explore (a) the overall predictive ability of the ILH, (b) the relative effects of different components of the ILH…

This meta-analysis aimed to clarify the complex relationship between repetition and second language (L2) incidental vocabulary learning by meta-analyzing primary studies reporting correlation coefficients between the number of encounters and vocabulary learning. We synthesized and quantitatively analyzed 45 effect sizes from 26 studies (N = 1,918)…

The main findings of a meta-analysis of 23 research reports were the following: giving behavioral objectives, learning directions, or questions before an instructional text is read leads to some improvement in the learning of goal relevant material; however, these preinstructional acts impede the learning of goal irrelevant materials.

Reviews current literature in the fields of computer science and education that is related to the structure and use of hypermedia; discusses discovery and incidental learning; examines the nature of the environment and of the learner; describes implications for the design of hypermedia-assisted instruction (HAI); and suggests further research…
