This study is a corpus study on morphological features of children's books in Turkish. The purpose of the study is to determine derivational and inflectional suffixes in Turkish children books and to identify the common and productive morphemes used in child literature in the light of the information obtained; hence, reach clues about determining…

This study investigated the effect of derivational suffix instruction on vocabulary knowledge. Fifty-eight high school learners were recruited to participate in the study. The learners were divided into control (n = 29) and experimental (n = 29) groups. The experimental group received a Fundamental English II course with an emphasis on…

Vocabulary learning strategies are essential in vocabulary acquisition and one particularly important strategy is word part strategy. This quasi-experimental research attempted to investigate the effects of word part strategy instruction on vocabulary knowledge among primary school students in a Thai EFL context. It also sought to explore primary…

This study explores the effects of receptive derivational affix knowledge, derivative frequency, part of speech, and vocabulary breadth on production of derivatives. Twenty-one speakers of English as a first language and 107 learners of English as a second language were asked to produce derivatives for 90 prompt words on a decontextualized…

Research has indicated that first language (L1) English speakers acquire derivational knowledge--the ability to understand and produce derived forms of a word--through increased exposure to the language (e.g., Anglin, 1993). Second language (L2) research has shown that L2 English learners tend to have limited productive derivational knowledge in…

Background: Morphological analysis skill is the ability to problem-solve meanings of unfamiliar words by applying knowledge of morphological constituents. For vocabulary words from the academic layer of English, the major, meaning-carrying morphological constituents are Latin roots (nov meaning 'new' in innovative). The degree to which…

Word learning in a second language (L2) is a complex process, which is affected by learner-related (e.g., morphological awareness) and language-related (e.g., word semantic transparency) factors. Morphological awareness is learners' sensitivity to the morphological structure of printed words, and semantic transparency is the degree to which…

Generalization is the ability to apply regularities to novel instances, for example, correctly guessing that the plural for the novel English word 'wug' should be 'wugs'. Early language learners make overgeneralization errors like 'mouses', applying regularities beyond their attested uses. Theories concerned with the question of how learners learn…

A nonrandomized quasi-experimental, mixed-method double pretest-posttest design was used to compare the effects of a multilinguistic word study model of instruction -- RAVE-O program (Wolf, Miller, & Donnelly, 2000) -- in comparison with a phonics word study model of instruction -- Fountas and Pinnell Phonics Lessons -- Letters, words, and how…

Vulnerability of morphosyntactic production, including grammatical aspect, has been identified in at least some children with autism spectrum disorder (ASD) exposed to typologically different languages. However, Tovar et al. (2015) found strengths in comprehending grammatical aspect in English-exposed children with ASD, suggesting that the…

This study investigated how word and child characteristics affect children's ability to learn the meanings of novel words. Participants were fourth- and fifth-graders representing native English speakers (NE) and bilingual learners with fluent English proficiency (FEP) and designated English Learners (EL). Students were taught the meanings of a…

This article synthesizes the roles of morphology in English reading acquisition and reports a meta-analytic structural equation modeling study (k = 107, N = 21,818) that tested the effects of morphological awareness (MA) on reading comprehension in school-aged readers. Moderator analysis was conducted through a set of subgroup comparisons based on…

Morphological analysis and incidental learning are two vocabulary learning strategies that language learners may use in order to acquire the meanings of new words. To date, however, few studies have compared the effectiveness of these two strategies. Hence, the current study was carried out to compare the effect of morphological analysis and…

Given that words from the academic layer of English typically carry bound roots ("min" in "diminish") rather than free-standing base words ("small" in "smaller"), there is a need to understand the factors that make bound roots more or less accessible for morphological problem-solving unfamiliar words. We…

This study explored whether form-focused instruction (FFI) and peer corrective feedback (CF) facilitated vocabulary development during peer interaction (PI). Third-semester learners of German were assigned to a PI group (peer interaction only), PI FFI group (peer interaction and form-focused instruction), or PI FFI CF group (peer interaction,…
