Comparing the Effects of Different Post-Listening Output Tasks on Second Language Incidental Vocabulary Acquisition: Revisiting the Involvement Load Hypothesis

Based on the Involvement Load Hypothesis, the present study investigated the differential effects of three post-listening output tasks (gap-filling, translation, and sentence-making) on immediate acquisition and retention of such vocabulary dimensions as productive knowledge of orthography, receptive recall of meaning and form, and productive knowledge of grammatical functions. Ninety second-year English majors were divided into three groups to finish listening plus one of the post-listening tasks. The results showed that the post-listening output tasks had positive effects on immediate acquisition of productive vocabulary knowledge, partially in agreement with the Involvement Load Hypothesis. However, the effects on vocabulary knowledge retention were found to be largely inconsistent with the Involvement Load Hypothesis. The finding thus challenges this hypothesis in that involvement load is not the only determining factor and suggests that the theoretical construct of involvement load should be constructed with more caution.

Task-induced Involvement Load, Vocabulary learning and Reading Comprehension Among Iranian Intermediate English as a Foreign Language Learners

The importance of vocabulary in a second language is so self-axiomatic that it renders learning and teaching a must. The present study aimed to explore whether the manipulation of the task components, as proposed by Laufer and Hulstijn, affected the acquisition of English vocabularies by EFL learners. The present study followed an experimental design in that it used pre-test and post-test to collect data from the participants. The current research included 50 EFL students from two private English language institutions in Yazd, Iran. The study included two distinct reading tasks that placed varying loads on participants. The two reading texts were controlled for their difficulty level: one with the high level of involvement load and the other with lack of involvement load, thus two experimental groups. There was a reading comprehension exam for those who participated in the first experimental group (with a high involvement load). Reading comprehension was assessed using the first Vocabulary Knowledge Scale (VKS1), which measures vocabulary knowledge. The second reading comprehension assignment was simultaneously presented to the second experimental group (the one with a low involvement load). After two weeks, they were administered VKS2, and their results were recorded. Analyzing the data was done by using independent t-tests. Exposure to high levels of involvement load has been shown to impact vocabulary development in English learners. This is despite respondents being able to recall more words from high-involvement vocabulary acquisitions than from low-involvement vocabulary acquisitions. Findings from this study may be used to construct practical tasks of reading with suitable degrees of difficulty for English language learners (EFL/ESL) teachers and vocabulary instructors.

INVOLVEMENT LOAD HYPOTHESIS PLUS

The present meta-analysis aimed to improve on Involvement Load Hypothesis (ILH) by incorporating it into a broader framework that predicts incidental vocabulary learning. Studies testing the ILH were systematically collected and 42 studies meeting our inclusion criteria were analyzed. The model-selection approach was used to determine the optimal statistical model (i.e., a set of predictor variables) that best predicts learning gains. Following previous findings, we investigated whether the prediction of the ILH improved by (a) examining the influence of each level of individual ILH components (need, search, and evaluation), (b) adopting optimal operationalization of the ILH components and test format grouping, and (c) including other empirically motivated variables. Results showed that the resulting models explained a greater variance in learning gains. Based on the models, we created incidental vocabulary learning formulas. Using these formulas, one can calculate the effectiveness index of activities to predict their relative effectiveness more accurately on incidental vocabulary learning.

Manipulation of the Involvement Load of L2 Reading Tasks: A Useful Heuristic for Enhanced L2 Vocabulary Development

Ensuring second language (L2) learners have an adequate breadth and depth of L2 vocabulary knowledge is a key pedagogical objective in L2 learning contexts. For this reason, establishing guiding principles that successfully enhance the efficacy of L2 vocabulary knowledge development is of strong importance. The current study investigated the value of applying principles from the Involvement Load Hypothesis (ILH) as part of a reading comprehension task among 40 intermediate English as a foreign language (EFL) students. Half of the group undertook a high involvement reading task, whereas the other half undertook a low involvement reading task. After the reading task, an unannounced Vocabulary Knowledge Scale test was administered to measure incidental vocabulary gains. Results showed the high involvement group remarkably outflanked the low involvement groups in terms of the target words learned from the reading task. A delayed post-test indicated that the retention of target word knowledge was more robust among the high involvement group, but that this difference did not maintain a level of statistical significance after 2 weeks. We conclude with suggestions about how EFL/ESL instructors can apply the principles of the ILH in efforts to systematically enhance learners’ L2 vocabulary knowledge.

HOW THE CO-CREATIVE PROCESS AFFECTS CONCEPT FORMATION

The importance of forming concepts in one's mind has been argued from various perspectives in design studies. This experimental study examines how the co-creative process affects concept formation considering its depth.The authors conducted a learning experiment applying three processes; non-interactive (NI), interactive but non-co-creative (NC), and interactive and co-creative processes (C). To evaluate whether and how deep the concept is formed in the examinee's mind, mimetic Japanese words, which contain several different explicit concepts underlying a certain integrated implicit concept, were chosen as learning materials. The examinees without any knowledge about mimetic Japanese words were gathered globally and the experiment was conducted fully online using English. Examinees were tested several times to measure how they had formed these concepts for comparing the processes.The findings suggest that the co-creative process enhances the depth of concept formation: involvement load and willingness to participate in the co-creative process lead to deeper concept formation.

A Study on the Effects of Chinese EFL Learners’ English Proficiency and Involvement Load on Incidental Vocabulary Acquisition

The effects of EFL learners’ English proficiency and involvement load induced by tasks on incidental vocabulary acquisition are observed in this study. 163 students of non-English majors in a local university of China were divided into two groups of different English proficiency according to their scores of College English Test Band 4 (CET-4). The students in each group were randomly assigned one of three tasks (reading-for-comprehension, blank-filling, and writing) involving 10 target words. Fifteen minutes after they finished the task, they were required to take an immediate vocabulary test about the target words. Two weeks later, they were asked to take the same kind of vocabulary test to examine their delayed memory of the target words. All of the students did not know about the vocabulary tests beforehand. The results show that: in the process of immediate incidental vocabulary acquisition, both learners’ English proficiency and involvement load have a main effect on immediate memory, but the interactive effect of these two factors on incidental vocabulary acquisition is not significant; in the vocabulary retention test, learners’ English proficiency does not have a significant main effect on delayed memory, but the main effect of involvement load is still significant; at the same time, the interactive effect of these two factors is still not significant.

Task-induced involvement load, vocabulary learning in a foreign language, and their association with metacognition

This study examined the effects of involvement load-based tasks on vocabulary learning in a foreign language, as well as the extent to which task effects are predicted by learners’ metacognition (i.e. metacognitive knowledge and regulation). A total of 120 Chinese university students of English as a foreign language (EFL) were randomly assigned to four task conditions: (1) reading; (2) reading + gap-fill; (3) reading + writing; and (4) reading + writing with the use of a digital dictionary. The Vocabulary Knowledge Scale was adapted to measure condition effects. The Metacognitive Awareness Inventory was used to examine learners’ metacognitive knowledge and regulation. Results revealed that the group of learners who completed reading + writing tasks with the use of a digital dictionary demonstrated the best performance in acquiring receptive and productive vocabulary knowledge, followed by the reading + writing group, the reading + gap-fill group, and, finally, the reading only group. Multiple regression analysis supported the predictive effects of metacognitive regulation on task-based vocabulary learning. Structural equation modelling presented an overall profile of task-based vocabulary learning and metacognition. Based on the findings, we proposed a framework to understand the relationship between learners’ metacognition, task type, and L2 vocabulary learning.
