LXD Research was engaged by 95 Percent Group to conduct a third-party, mixed-methods efficacy study of their 95 Phonics Core Program (95 PCP) to evaluate the impact on fourth and fifth grade literacy outcomes over the school year 2023-2024. LXD analyzed the formative assessment data from i-Ready, focusing on overall scale scores, subdomains, and…

In 2012, New Jersey implemented a broad change to the teacher evaluation system with the Teacher Effectiveness and Accountability for the Children of New Jersey (TEACHNJ) Act which identified the Marzano Causal Teacher evaluation system as one of the prescribe models for districts to adopt. This system provides a more differentiated teacher…

Behavior rating scales represent one of the most commonly used types of assessments in school psychology. Yet, they suffer from a fundamental limitation: They are an indirect methodology influenced partially by student behavior and partially by rater perspectives. Thus, the current study utilized advanced analytic approaches to evaluate rater…

Handwriting is an important daily occupation for children. When assessing children's handwriting, it is recommended that clinicians use objective handwriting performance tests as well as solicit children's and parents' perspectives to promote client-centered practice. However, it remains unknown to what extent objective handwriting performance…

Curriculum-based measurement (CBM) has conventionally included accuracy criteria with recommended fluency thresholds for instructional decision-making. Some scholars have argued for the use of accuracy to directly determine instructional need (e.g., Szadokierski et al., 2017). However, accuracy and fluency have not been directly examined to…

Recent work has demonstrated that having students study worked examples and answer self-explanation prompts as part of their problem-solving practice improves learning on researcher-developed measures of mathematical proficiency. However, little work has been done to date to investigate whether these benefits translate to improvements on the types…

In October 2023, the California Department of Education released test scores for all students in Grades 3-8 and 11 for the 2022-23 school year. These results represent an opportunity to analyze whether and to what extent student learning has rebounded after the dramatic declines in scores resulting from the COVID-19 pandemic and related school…

Recent work has demonstrated that having students study worked examples and answer self-explanation prompts as part of their problem-solving practice improves learning on researcher-developed measures of mathematical proficiency. However, little work has been done to date to investigate whether these benefits translate to improvements on the types…

The objectives of this study were: (i) to compare the scores on the test between students who took a Chinese Traditional Culture course (including ancient fairy tales, traditional festivals, and ancient etiquette) and students who did not, (ii) to examine students' performance on the traditional culture after taking the Chinese Traditional Culture…

Valid and reliable measurements of teaching quality facilitate school-level decision-making and policies pertaining to teachers. Using nearly 1,000 word-to-word transcriptions of fourth- and fifth-grade English language arts classes, we apply novel text-as-data methods to develop automated measures of teaching to complement classroom observations…

Methods to handle ordered-categorical indicators in latent variable interactions have been developed, yet they have not been widely applied. This article compares the performance of two popular latent variable interaction modeling approaches in handling ordered-categorical indicators: unconstrained product indicator (UPI) and latent moderated…

Background: Previous studies used curriculum-based measurement (CBM) maze scores as an indicator of the reading comprehension level of secondary school students with and without special educational needs in multiple grades, pinpointing a high influence of both student- and context-related variables. However, studies on cumulative influence are…

Most studies of test-based promotion policies focus on measuring the effect of retention (being left back) on later student outcomes, and the evidence is fairly mixed. However, test-based promotion policies do not only affect the students who are retained. Presumably, they also affect students and schools as they try to improve reading performance…

This study analyzed the required inclusion of school test scores in the yearly evaluation of school principals within the current school reform and standards and accountability movements of both the federal and state departments of education. Extant data from a single school district in Oregon was used for this study, and included: (a)…

Despite the importance of analytic text-based writing, relatively little is known about how to teach to this important skill. A persistent barrier to conducting research that would provide insight on best practices for teaching this form of writing is a lack of outcome measures that assess students' analytic text-based writing development and that…
