Early mathematics achievement is a strong predictor of later mathematics achievement, and student competence in fractions and division may be the strongest predictor of success in secondary-level algebra. We used a multisite cluster-randomized trial to estimate the impact of a mathematics teacher professional development (PD) program on student…

Lesson study, especially when conducted with support from targeted resources, is often identified as a potentially effective means to support teacher learning. In this study, 80 school-based teams of educators, representing 80 classrooms of third- or fourth-grade students in the US, were randomly assigned to one of four conditions: lesson study…

This study was conducted to explore US elementary teachers' perceptions of their experiences using rubrics as a tool for student self-assessment and metacognition (assessment for learning) to improve elementary students' achievement and their instructional decision-making at a private American elementary school in South Florida. The constructivist…

Purpose and Method of Study: The purpose of this study was to compare the effectiveness of two approaches to professional development methodologies implemented in public schools. A quantitative, correlational research design was employed to determine whether the academic success in the core content areas of reading, writing, math and science could…

Despite the use of literacy coaching to help improve the instructional practices of teachers and increase reading achievement, data of the National Assessment of Education Progress (NAEP) indicate that Florida's students are averaging about 60% below NAEP proficient level. This dissertation reported the results of a nonexperimental study that…

The purpose of this quantitative correlational study was to describe the associations between the specific Central Florida district's final instructional summative evaluation scores and student achievement scores for Grade 4 instructional staff teaching ELA or mathematics within the district for the school year 2017-2018. The self-determination…

The purpose of this quantitative ex post-facto study was to determine if differences exist in 4th-grade students' reading and math learning outcomes between co-taught classrooms and traditional classrooms in a Florida public school district. The study was conducted with archival data from the school district's fall and winter progress monitoring…

Many studies conducted in the last decades report that very few elementary-grades students understand the meaning of = in mathematics, and that upper-elementary students do not understand it any better than the lower-elementary students do. Using data from thousands of Florida elementary students, we show that students in Florida perform ten to…

Research has established that reading and writing skills are closely linked for most individuals, which can be explained by the shared knowledge and functional relations theoretical perspectives. The current study used quantile regression to explore differences between and within Grades 3-5 in the United States in the associations between a…

Science, technology, engineering, and mathematics (STEM) programs serving students from low socioeconomic areas are understudied in the literature. More research studies need to be conducted to make informed instructional decisions for students who may be at a disadvantage compared to their peers from higher socioeconomic areas. The purpose of…

The shift from the traditional self-contained classroom to the departmentalized classroom structure in upper-elementary classrooms is increasing as the pressure to maximize student outcomes is higher than ever for public schools. Teachers prefer departmentalization but findings as to its benefits for students are mixed. This study considers the…

Standardized testing is generally regarded in schools today as the primary way to measure and determine student achievement. Student performance determines the degree to which schools, teachers, and students are identified as being successful. The problem being investigated by this study was that all students are spending too much classroom…

A Comprehensive K-3 Reading Policy establishes support and intensive reading interventions for K-3 students to ensure they read on grade level by the end of third grade. The policy also requires third grade students to demonstrate sufficient reading skills for promotion to fourth grade. For students severely below grade level and who do not…

Purpose: The purpose of this study was to determine if a direct, explicit method of teaching vocabulary with the Vocabulary Scenario Technique -- General Education 16 Encounter (VSTGE16) protocol would yield gains in the vocabulary knowledge of fourth grade students in a general education classroom. Two research questions examined whether fourth…

Computer science (CS) and computational thinking (a problem-solving process used by computer scientists) teach students design, logical reasoning, and problem solving--skills that are valuable in life and in any career. Computational thinking (CT) concepts such as decomposition teach students how to break down and tackle a large complex problem.…
