Research into Family Language Policy (FLP) focuses on language planning by and among family members within home spaces. In this study we gather data from multilingual young adults with different backgrounds across Mexico through an online questionnaire. We use a trajectory approach to look at how FLP changes over time and space from the…

One of the essential characteristics of the human being as social existence is his ability to communicate with his environment. There are many ways for people to communicate. However, the most preferred form of communication in interpersonal relations was primarily speaking. Effective use of speaking skills can be said to be possible if…

Argumentation is an important mathematical practice, highlighted by research and policy documents that describe ways to structure reform-oriented classrooms (Nardi and Knuth 2017; NCTM 2000; NGA Center and CCSSI 2010). Participating in argumentation can enhance students' mathematics learning as they make sense of mathematical ideas, provide…

Constructing formal geometry proofs in is an important topic in the mathematics curriculum. But students' difficulties with proof are well documented. This article focuses on proofs that use triangle congruence postulates in US high school geometry. Examining students' proof reasoning in one-on-one task-based interviews, we analyzed students' oral…

Research has revealed the extent and mechanism of the relation between language (dominated by alphabetic systems) and students' mathematics learning, but when it comes to Chinese language (an orthographic system), nature remains elusive. In this meta-analysis we aim to quantify the size of the relation between Chinese language and mathematics and…

Background: Previous work suggests that children can teach themselves new written words via reading aloud texts independently (i.e., orthographic learning via self-teaching). In self-teaching in Chinese, regular phonetic radicals and transparent semantic radicals facilitate orthographic learning. The present study examined the roles of phonetic…

Written text production remains a relatively under-explored area in the child development literature, not only for typically developing (TD) children, but also for children with Developmental Language Disorder (DLD), despite its important role for academic performance and life success. The present study attempts the combined investigation of…

Intelligibility is a critically important aspect for effective oral communication. This study explored salient (important) pronunciation errors and their relative roles in the intelligibility of nonnative speech based on listener judgments. Speech samples, collected from speakers with a Turkish as a native language (L1) background, were presented…

This study investigated the effects of L2 pronunciation instruction on speech intelligibility and fluency, the relationship between intelligibility and fluency, and the extent to which utterance fluency can predict perceived fluency. Participants were 30 beginning adult EFL learners who received either segmental or suprasegmental instruction. Oral…

This manuscript reports on a study carried out at a public university in southeast Mexico aimed to determine whether changes in the instructional design of an online English course benefit students' oral communicative competence. The research followed a quantitative quasi-experimental design that involved two groups of students. One of them took a…

Over half of US children are enrolled in preschools, where the quantity and quality of language input from teachers are likely to affect children's language development. Leveraging repeated objective measurements, we examined the rate per minute and phonemic diversity of child and teacher speech-related vocalizations in preschool classrooms and…

A child's ability to understand text (reading comprehension) can greatly impact both their ability to learn in the classroom and their future contributions to society. Reading comprehension draws on oral language; behavioural measures of knowledge at the word and sentence levels have been shown to be related to children's reading comprehension. In…

This article reports on a longitudinal, quasi-experimental comparison of two English language development (ELD) models implemented from kindergarten through Grade 3 to support oral English language development among Spanish-speaking English language learners (ELLs). Specifically, the study examined oral English language proficiency among students…

An AB single case design was used to measure the effect of data-based feedback for 6 children in a listening and spoken language early intervention (EI) programme in Australia. Changes in the number of parent-child conversational turns following feedback were measured using an automated language environment analysis system. The perceived value and…

This study investigated the development and utilization of argument and representation resources in pre-service science teachers' (PSTs') written and oral arguments over two semesters in an argument-based inquiry environment of General Chemistry Laboratory I and II courses. The study employed a form of mixed methods research that is known as…
