In recent years, many states have adopted Item Response Theory (IRT) based vertically scaled tests due to their compelling features in a growth-based accountability context. However, selection of a practical and effective calibration/scaling method and proper understanding of issues with possible multidimensionality in the test data is critical to…

Elementary instruction of fifth grade classrooms was found to be primarily in two organizational models in a school district northwest of Atlanta, Georgia. The self-contained classroom provided a generalist teacher responsible for the instruction of all academic subjects to one group of students throughout the day, while departmentalized…

The purpose of this research project was to evaluate fifth grade teacher mathematical content knowledge, compare that mathematical content knowledge to efficacy in teaching the new rigorous mathematical standards, and to ascertain if these two factors played a role in student achievement. Quantitative results were derived from student assessment…

The equipartitioning learning trajectory (Confrey, Maloney, Nguyen, Mojica & Myers, 2009) has been hypothesized and the proficiency levels have been validated through much prior work. This study solidifies understanding of the upper level of co-splitting, which has been redefined through further clinical interview work (Corley, Confrey &…

This study was conducted to determine whether a lesson, in which context-based learning approach and scientific stories were used, changed stereotypical images of students (aged 11-12) about science and scientists. Data was collected from two separate sources: Interviews conducted with six students and Draw a Scientist Test (DAST) document that…

"Scott Foresman-Addison Wesley Elementary Mathematics" is a core mathematics curriculum for students in prekindergarten through grade 6. The program aims to improve students' understanding of key math concepts through problem-solving instruction, hands-on activities, and math problems that involve reading and writing. The curriculum…

This study assessed the anthropometrics and acanthosis nigricans (AN) in a sample of 7,337 children at two assessments. Four groups of children were identified based on the presence of AN at both time points: those who never had the marker, those who gained the marker, those who lost the marker, and those who maintained the marker. Group…

The purpose of this research was to investigate how domain-specific importance ratings affect relations between perceived competence and self-worth among African American school-age children. Importance ratings have been found to affect the strength of the relationship between perceived competence and self-worth and have implications for…

Measures of phonological and morphological awareness of Chinese were administered to 94 third-grade students of Chinese in Taiwan to evaluate their relative contributions to current and prospective prediction of early reading in Chinese L1 and English L2. Phonological awareness made a significant unique contribution to Chinese character reading…

Pedagogical competence and teaching efficacy significantly influence the quality of classroom science learning. Without applying pedagogical learning in realistic classroom environments, there is slight possibility that prospective teachers will increase their teaching confidence or develop understanding of how learners acquire and construct…

The aim of this study was to examine the effect of progressive sentence development activities on 5th graders' description skills. The study was conducted based on the pretest-posttest quasi-experimental model with a control group. A total of 58 students participated in the study; 29 in the control group, and 29 in the experimental group. The…

Archaeology provides the chance to ask questions about human culture, past and present, using artifacts as evidence. By studying archaeology, students learn about how people in their region found and prepared food, responded to changes in their environment (e.g., flooding, earthquakes, droughts), and interacted with other peoples. This article…

In 2 experiments the authors investigated whether assigning a perspective to middle school students prior to reading a long informational text would improve their reading comprehension. Pretest-posttest control group designs were employed in both experiments, in Experiment 1 (n = 146 fifth- and sixth-grade students) and in Experiment 2 (n = 83…

Background: One of the objectives of the new Spanish Education Act is for students to develop a series of social skills, largely derived from the ability variables of assertiveness and empathy. Sport Education is an instructional model that is deemed useful in the development of personal and social responsibility and social values. It requires…

In this study, we examined whether orthographic learning can be demonstrated in disabled readers learning to read in a transparent orthography (Dutch). In addition, we tested the effect of the use of text-to-speech software, a new form of direct instruction, on orthographic learning. Both research goals were investigated by replicating Share's…
