A rich home literacy environment (HLE) fosters students’ academic achievement. However, the link between HLE and children’s reading comprehension is unclear. This study examined the effects of HLE factors on children’s reading comprehension through a meta-analysis of 59 studies conducted between 1998 and 2018. Results of the meta-analysis indicated three main findings. First, the overall positive correlation between HLE and children’s reading comprehension was moderate (z = .32). Second, sampling area, type of home literacy resource and parental involvement styles did not show a significant interaction effect between each HLE factor and children’s reading comprehension. Third, parents’ involvement and literacy expectations of children had a significantly higher correlation with children’s reading comprehension than home literacy resources did. Findings of this study suggest that parental literacy activities involvement and parental literacy expectations contribute more to children's literacy knowledge enhancement.

This study synthesized the correlation between reading strategy and reading comprehension of four categories based on Weinstein and Mayer's reading strategy model. The current meta-analysis obtained 57 effect sizes that represented 21,548 readers, and all selected materials came from empirical studies published from 1998 to 2019. Results showed that reading strategies in all the four categories had a similar correlation effect size with reading comprehension. The correlation between monitoring strategy and reading comprehension was significantly larger in first language scripts than second language scripts. Affective strategy and elaboration strategy had an independent effect on reading comprehension, which was not significantly moderated by selected moderators. Results suggested that the reading strategies of all the four categories may have a similar contribution to text comprehension activities.

This paper is a quantitative synthesis of research on home literacy environment (HLE) and children’s English as a second language (ESL) learning outcomes through a meta-analysis of 18 articles in kindergarten, primary, and secondary school students (N = 4401) carried out between 2000 and 2018. It examines the associations between HLE factors and children’s ESL performance. Results showed the effect sizes between HLE factors and children’s ESL performance was small to moderate. Family members shared a similar effect size on children’s ESL performance. Parental literacy teaching behaviors have stronger effects on children’s ESL ability than parental beliefs on their children’s English learning and the availability of learning resources at home. These results highlight the importance of HLE and indicate the relative contributions of specific HLE factors on children’s ESL acquisition.

As an effective teaching approach that allows teachers and students to interact collaboratively and actively build on each other’s ideas, dialogic teaching can enhance classroom engagement and learning outcomes. This study addresses the use of dialogic teaching for improving English language learning among Chinese children with varied levels of English vocabulary. It focuses on the effects of dialogic teaching on vocabulary knowledge and phonological awareness. Seventy-two first graders from Hong Kong primary schools were tested on English vocabulary knowledge and phonological awareness and were assigned to control and experimental conditions. A 12-week dialogic teaching intervention was implemented in daily English lessons. Results from repeated measures ANOVA showed that students in the experimental condition with dialogic teaching implemented exhibited significantly greater growth in expressive vocabulary knowledge on textbook items in both low and high vocabulary groups, and greater gain in phonological awareness in the high vocabulary group, than those in the control condition. These results suggest that dialogic teaching in English-as-a-second-language (ESL) classroom enhances English language development in young ESL learners. In addition, when assessing the effectiveness of dialogic teaching in young children’s second language classroom context, it is important to consider its differential effects on children with diverse vocabulary levels.

Metalinguistic knowledge has a facilitative effect on reading comprehension. This meta-analysis examined the relationship between metalinguistic knowledge and reading comprehension among Chinese students. By focusing on both Chinese and English scripts' reading comprehension performance, this study synthesized 46 studies with 73 independent samples that represented 10,793 Chinese students from primary school to university levels. We found that in both Chinese and English scripts' reading, morphological awareness had the strongest correlation with reading comprehension, whereas both phonological awareness and orthographical skill had a similar medium correlation with reading comprehension. All three metalinguistic knowledge, which was not significantly influenced by the selected moderators of grade group, area, language type, and assessment, had an independent correlation with reading comprehension. The results suggested that reading stages did not significantly impact the function of metalinguistic knowledge on both Chinese and English scripts' reading comprehension for Chinese students. In addition, for Chinese students, morphological awareness plays a more important role than phonological awareness and orthographical skill in both Chinese and English scripts' reading comprehension.

The study aimed to examine the cohesive tie effect on reading comprehension through the grammatical knowledge cognition process. The present meta-analysis examined the correlation between grammatical knowledge and reading comprehension based on empirical results published between 1998 and 2021. This study selected 86 studies with a total of 14,852 readers whose grades were grouped from primary school to university. The results showed that the overall correlation effect size between grammatical knowledge and reading comprehension was large, and the significant interaction effect of the grade group was confirmed through moderator analysis. The results suggested that the grammatical knowledge’s function of the cohesive tie has a transfer effect across different text comprehension scripts.
