Child-directed language can support language learning, but how? We addressed two questions: (1) how caregivers prosodically modulated their speech as a function of word familiarity (known or unknown to the child) and accessibility of referent (visually present or absent from the immediate environment); (2) whether such modulations affect…

When the course materials prepared in the field of teaching Turkish to foreigners are carefully examined, there is no holistic consistency regarding the instructional design. Dimensions such as theme and unit starters, to what extent and how grammar is handled, to what extent and with what kind of design skills are included, what kind of strategy…

A large body of research has been carried out on integrating picture dictionaries in EFL classes globally; however, a gap in the literature has been noticed on their effects at the tertiary level in the Iraq context. To address this issue, this paper, for the first time in the literature, focuses on the effects of the Oxford Picture Dictionary on…

This quantitative study examines the Lexile level, estimated volume, and genre of fourth- and fifth-grade texts used in four popular core reading series to analyze the programs' possible effects on instruction and comprehension. The four series include Houghton Mifflin Harcourt's Into Reading, Lucy Calkins' Units of Study for Teaching Reading,…

This study examined the variations between providing secondary-school teachers with collaborative professional development (PD) and traditional PD. Although the U.S. local and federal governments spend billions of dollars on teacher PDs each year, there is still a debate on the effectiveness of those trainings. Research suggests that the most…

By 12 months, English-learning infants have an awareness of the sound patterns of word forms that constitute acceptable labels for objects in their native language. In the following experiments, we replicated and extended previous findings that Canadian English-learning infants will not link function-like words with novel objects. Across three…

This study will address how translation tools could be incorporated into the curricula of terminology courses for translators in Iran taking language policy and planning in Iran into consideration. One of the main objectives of this study is to argue that terminology courses in Iran are different from those offered in some other universities in…

Recreational reading is in a decline for upper elementary aged readers, and along with this decline comes consequent declines in students' ability to make meaning from what they read and their acquisition of different language forms, including the acquisition of new vocabulary words. However, one reading format is increasing in popularity: graphic…

Facilitating the transformation of vocabulary from receptive to productive can be challenging for second language (L2) teachers. Although some studies have focused on understanding activities that promote productive vocabulary in written modes (e.g., Teng & Xu, 2022), little is known about the effect of activities on productive vocabulary in…

Purpose: The current investigation evaluated the extent to which early noun, verb, and adjective lexicon sizes predicted later grammatical outcomes in Mandarin-speaking children with and without late language emergence (LLE) using a parent report. Method: In Study 1, the parents of 24 Mandarin-speaking children with typical language filled out the…

Developmental science has increasingly scrutinized how environmental hazards influence child outcomes, but few studies examine how contaminants affect disparities in early skill formation. Linking research on environmental inequality and early childhood development, this study assessed whether differences in exposure to neurotoxic lead explain…

In this manuscript we show how readalouds can significantly enrich student vocabulary and comprehension by demonstrating enhancements that will foster student learning and language development. We anchor our examples to empirical evidence demonstrating that the content of a readaloud (i.e., the what we teach) as well as the quality of the…

This study investigated whether seeing iconic gestures depicting verb referents promotes two types of generalization. We taught 3- to 4-year-olds novel locomotion verbs. Children who saw iconic manner gestures during training generalized more verbs to novel events ("first-order generalization") than children who saw interactive gestures…

A key question in developmental research concerns how children learn associations between words and meanings in their early language development. Given a vast array of possible referents, how does the child know what a word refers to? We contend that onomatopoeia (e.g. "knock," "meow"), where a word's sound evokes the sound…

The authors look back on their participation in three successful multiyear research studies focused on multifaceted vocabulary instruction and distill four overarching lessons that provide practical guidance to schools and teachers interested in implementing effective comprehensive vocabulary instruction. Specifically, they elaborate on the value…
