Abstract
Research indicates that L2 words can be learned incidentally through watching audio-visual materials.
Gap in the literature: Previous studies focused largely on incidental vocabulary learning through reading, not through viewing a full-length TV program.
This study investigates incidental vocabulary learning via L2 television and examines factors affecting learning:
Frequency of occurrence.
Cognateness.
Word relevance.
Prior vocabulary knowledge.
Two experiments conducted with Dutch-speaking EFL learners:
Experiment 1: Effects on form recognition and meaning recall.
Experiment 2: Effects on meaning recognition.
Findings reveal that viewing TV can lead to significant incidental vocabulary learning, impacted by frequency of occurrence, prior knowledge, and cognateness.
Introduction and Background
Major need to explore how watching L2 television affects vocabulary acquisition.
Note:
English learners need approximately 3,000 word families for spoken discourse and 8,000-9,000 word families for written discourse (sources include Van Zeeland & Schmitt, 2013; Nation, 2006).
Limited classroom time prevents thorough vocabulary acquisition, prompting interest in supplementary methods like extensive reading and TV viewing.
Previous studies have shown possible incidental vocabulary acquisition via short clips; however, the impact of a full-length TV show remains unexplored.
Worth noting:
86% of EU residents watch TV daily (European Commission, 2014).
Substantial viewing habits in English are reported among foreign language learners, surpassing reading (Lindgren & Muñoz, 2013).
Research shows audiovisual input can support language proficiency and vocabulary acquisition (Lindgren & Muñoz, 2013; Peters, in press).
The study aims to bridge the gap in literature regarding the role of TV in incidental vocabulary acquisition.
Literature Review
Incidental Vocabulary Acquisition
Vocabulary learning through reading has been well-documented (e.g., Horst, Cobb, & Meara, 1998).
Studies show L2 vocabulary may be incidentally learned through educational clips but not yet through a full-length TV program.
Webb and Rodgers (2009a) advocate for TV viewing to enhance vocabulary due to its ability to expose learners to low-frequency words through repetition within viewing contexts.
Word-Related Factors Affecting Vocabulary Learning
Frequency of Occurrence
Repeated encounters with words enhance vocabulary learning.
Evidence shows that 8–10 encounters lead to significant gains.
Listening studies are less extensive; results vary based on delivery method (Vidal, 2003).
Cognates
Defined as words that share phonological, orthographic, and semantic similarities (e.g., house/haus).
Cognates tend to be easier for learners to grasp (de Groot & Keijzer, 2000).
Limited research available regarding cognate impact in TV studies, yet relevance to L1 similarities noted (d’Ydewalle & Van de Poel, 1999).
Word Relevance
Defined as task-induced relevance; relevant words essential for comprehension (Peters, 2007).
Limited research in this area, highlighting the need to investigate word relevance further in TV contexts.
Learner-Related Factors Affecting Vocabulary Learning
Prior Vocabulary Knowledge
Learners with robust vocabulary achieve better text comprehension (Laufer & Ravenhorst-Kalovski, 2010).
Prior knowledge correlates positively with incidental learning gains (Horst et al., 1998).
Results inconsistent across studies focused on TV viewing; mixed outcomes concerning the impact of prior vocabulary knowledge on learning gains.
Methodology
Experiment Design
Two distinct experiments using pretest-posttest-delayed posttest between-participant designs.
Participants: primarily Dutch-speaking EFL learners, assigned randomly to experimental (viewing) or control (no viewing) groups.
Experimental Setup
Experiment 1: Form Recognition and Meaning Recall
Participants: 63 Dutch EFL business students (intermediate proficiency).
Authentic material: One-hour BBC documentary on J. M. Keynes.
Measures: Form recognition, meaning recall assessed using rating scale and multiple-choice formats.
Data collection over three sessions, included pretests, treatment, questionnaires, and posttests.
Experiment 2: Meaning Recognition
Participants: 62 learners engaging in meaning recognition tests (multiple-choice format).
Focused on evaluating whether watching TV influenced meaning recognition without a test-learning effect from prior sessions.
Results
Experiment 1 Findings
Form Recognition
ANCOVA results showed prior knowledge did not impact learning gains meaningfully.
Meaning Recall
Experimental group learned an average of four words (8.31% increase), while control group learned 1.5 words (3.35% increase).
ANCOVA results indicate significant variance explained by treatment and prior knowledge.
Experiment 2 Findings
Meaning Recognition
Experimental group: significant gains compared to control group (14% increase).
ANCOVA findings indicate treatment accounted for 8% of variance; prior knowledge showed a 19% variance.
Discussion
Significance of Findings
Affirmed that viewing full-length TV programs positively impacts incidental vocabulary learning.
Prior knowledge, frequency of occurrence, and cognateness were key factors influencing vocabulary acquisition.
Notably, word relevance did not show significant effects.
Recommendations
Educators should leverage TV viewing with structured support to enhance incidental learning opportunities.
Future research needed on lexical acquisition contexts, different input modalities, and long-term impacts.
