The present study presents an instructional procedure developed in an attempt to enhance incidental learning through graded readers in class, the Multiple Incidental Exposures (MIE) procedure, and compares it to a more common procedure involving reading and doing the exercises, which is referred to as Traditional Explicit Practice (TEP). Participants were 44 Catalan/Spanish students (aged 10-11 years) taking the fifth course of primary education in a school in Catalonia. Participants belonged to two intact classes that were randomly assigned a condition: MIE group (n = 23, n = 15 males, n = 8 females) and the TEP group (n = 21, n = 12 males, n = 9 females). The MIE group was first told the story by their teacher, then read and listened to the graded readers twice (first collectively and later on individually), to be followed by a True/False activity and a jigsaw reading task. The TEP group read and listened to the story collectively once and then performed a series of traditional explicit exercises very similar in format to those included at the end of the graded reader. Participants were administered a vocabulary test, a grammar test and a perception of pronunciation test following a pre- post-test design. A questionnaire on the participants' attitudes was also administered on the post-test. The results show that while the TEP procedure is more effective for grammar learning, the MIE and TEP procedures are equally effective in terms of vocabulary and pronunciation. In terms of enjoyment and perception of learning, both groups showed comparable results.
