In this study, we examined the relation of observed classroom practices to language and literacy achievement and the moderation of this relation for students from pre-K to sixth grade. A total of 136 studies (N = 107,882 participants) met the inclusion criteria, of which 108 studies were included for meta-analysis and the other 28 studies were narratively synthesized. The average zero-order (r = 0.12) and partial correlations (r[subscript p] = 0.04) were statistically significant but weak in magnitude. The relation was slightly weaker in upper than in lower grade levels, and stronger for observations capturing macro quality and instructional dimension than those capturing micro measurement and emotional or structural dimension, respectively. The relation did not vary by observation duration, frequency, adopted statistical approach, or type of covariates. Taken together with the narrative synthesis, the results highlight the complex nature of classroom observation and a need for more classroom research, particularly on higher grade levels.

We investigated the relations among theory of mind (ToM), mental state talk, and discourse comprehension. Specifically, we examined the frequency of mental state talk in children's oral recall of narrative texts and informational texts as well as relations among ToM, mental state talk (inclusion of mental state words in the recall of narrative and informational texts), and narrative and informational text comprehension. Results from children in Grade 4 (N = 132; M[subscript age] = 10.39 years) revealed that a greater number of mental state talk instances appeared in children's recall of narrative texts than in their recall of informational texts, but the mean number also differed across texts within a genre. ToM skill predicted the extent of mental state talk in narrative texts and informational texts, and the relation was stronger for narrative texts than for informational texts, after accounting for vocabulary, grammatical knowledge, working memory, and attentional control. Mental state talk in narrative texts was extremely strongly related to narrative comprehension, whereas mental state talk in informational texts was weakly related to informational text comprehension. Results suggest that ToM skill relates to mental state talk in the recall of texts, and both ToM and mental state talk play greater roles in comprehension of narrative texts than in comprehension of informational texts.

Purpose: Children's ability to adjust one's language according to discourse context is important for success in academic settings. This study examined whether second graders vary in linguistic and discourse features depending on discourse contexts, that is, when describing pictures in contextualized (describing the picture to an examiner while looking at it together) and decontextualized (pretending to describe the picture to a friend while sitting in front of the examiner) conditions. Method: A total of 330 English-speaking second graders in the United States (M[subscript age] = 7.33 years; 53% boys; 55% Caucasian children, 35% African American children) described three pictures in contextualized and decontextualized conditions. Children's picture descriptions were transcribed verbatim and coded for linguistic (e.g., elaborated noun phrase) and discourse (e.g., proper character introduction, degree of decontextualization) features. Results: Type-token ratio was higher in the contextualized condition than in the decontextualized condition, whereas certain types of elaborated noun phrases (e.g., simple descriptive noun phrase, noun phrase with postmodification), coordinating conjunctions, and nonclauses occurred more frequently in the decontextualized condition, controlling for total productivity and student demographics. The proportion of proper character introduction was higher in the decontextualized condition, whereas higher degrees of decontextualization and complex perspective-taking were found in the contextualized condition. Conclusion: Various linguistic and discourse cues illustrated the extent to which primary grade students employ their discourse knowledge when producing oral language.
