This study examined the relationship between reading fluency and reading comprehension of grade-level academic language. The CUBED Narrative Language Measures: Reading (NLM:R) subtest was used to assess the reading fluency and reading comprehension performance of 605 second- and third-grade students. The Measures of Academic Progress (MAP) reading assessment was also used to assess students' reading comprehension.

The Xdrop® droplet technology facilitates high-throughput compartmentalization of viable single cells or single-cell pairs in double-emulsion droplets, enabling the study of single cells or cell-cell interactions at an individual level. Effector cell molecule secretion and target cell killing can be evaluated independently or in combination.

- - This study tested a dynamic assessment approach to identify language disorders in a large, diverse group of 634 students from first to fifth grade, making it a significant contribution to the field.
- - The assessment, which took about 10 minutes, showed over 90% accuracy (sensitivity and specificity) in identifying language disorders and was equally effective across various demographic factors like age, race/ethnicity, and gender.
- - The findings suggest that this dynamic assessment may offer a more equitable method for classifying language disorders compared to traditional assessments, which can be biased.
Article Synopsis
- The study investigated factors linked to myopia progression and axial elongation in children with myopia.
- It analyzed data from a trial comparing atropine treatment with a placebo, focusing on children aged 5 to <13 with specific refractive errors and other characteristics.
- Results showed that younger children and those with higher initial myopia experienced more significant changes in refractive error and axial length, highlighting the need for treatments to slow progression in this at-risk group.
