Few longitudinal studies examine how "changes" in parent-child relationships are associated with changes in youth internalizing problems. In this longitudinal study, we investigated how developmental trends (linear change) and year-to-year lability (within-person fluctuations) in parental warmth and hostility across Grades 6 to 8 predict…

Little is known about the naturalistic development of mindfulness in adolescence and how it relates to changes in emotional well-being. The current longitudinal study examined the development of one dimension of mindfulness, nonreactivity to difficult inner experience (or in more colloquial terms, being able to notice, but "take a step…

Although a great deal of research exists regarding various components of the Writing-Based Practice along with best practice of writing instruction, the research that does exist only examines how writing instruction impacts writing. This research study, however, examined whether there is a potential connection between a writing immersion program,…

Many students' knowledge of fractions is adversely affected by whole number bias, the tendency to focus on the separate whole number components (numerator and denominator) of a fraction rather than on the fraction's integrated magnitude (ratio of numerator to denominator). Although whole number bias appears early in the fraction learning process…

The authors of this report aim to understand the health of the science, technology, engineering, and mathematics (STEM) education and labor market in the Appalachia region -- defined as the intersection of Ohio, Pennsylvania, and West Virginia -- with a focus on the mining and extraction industry. This report is the third in a three-part series.…

The purpose of this study was to explore the extent to which teachers in one high performing Southwestern Pennsylvania Middle School view the model and use of Professional Learning Community teams in their school with an existing survey instrument. Twenty-three of twenty-four teachers participated in this voluntary mail survey. The researcher used…

A secondary data analysis was conducted using a large dataset from a study related to online professional development for eighth grade teachers of mathematics. Using this data, the paper provides a snapshot of the current state of teachers' knowledge related to proportional reasoning and functions. The paper also considers how teachers' knowledge…

We examined developmental and individual differences in 6th and 8th graders' fraction arithmetic and overall mathematics achievement and related them to differences in understanding of fraction magnitudes, whole number division, executive functioning, and metacognitive judgments within a crosssectional design. Results indicated that the difference…

This second of five annual reports focuses on employment and wages in energy and advanced manufacturing-related industries and on science, technology, engineering, and mathematics (STEM) education indicators in the Appalachia Partnership Initiative (API) region, comprising twenty-seven counties in Ohio, Pennsylvania, and West Virginia. Together,…

Many students enter large comprehensive high schools without having the necessary social and academic skills or understanding of what will be expected of them as they move through the high school curriculum. To help a higher number of students experience success, schools must help them develop academic, social, and self-management skills.…

Why do girls perform so well academically yet lose ground as professional women? This diminishing number of women up the leadership hierarchy is often referred to as the "leaky pipeline," and attributed to many factors: external ones such as work environments not conducive to work/life balance, and internal ones such as women's own…

This first of five annual reports focuses on employment and wages in energy and advanced manufacturing--related industries and on science, technology, engineering, and mathematics (STEM) education indicators in the Appalachia Partnership Initiative (API) region. Together, these reports will capture trends over the next four years to (1) inform the…

Identifying means of assisting teachers in integrating technology during their instruction is becoming more important as the rate new technologies enter the classroom accelerates. The primary means of helping in-service teachers employ new technologies in their classrooms is frequently professional development. Unfortunately, professional…

Intelligent tutors have become increasingly accurate at detecting whether a student knows a skill, or knowledge component (KC), at a given time. However, current student models do not tell us exactly at which point a KC is learned. In this paper, we present a machine-learned model that assesses the probability that a student learned a KC at a…

Guided by a new framework, the NAEP science assessment was updated in 2009 to keep the content current with key developments in science, curriculum standards, assessments, and research. The 2009 framework organizes science content into three broad content areas. Physical science includes concepts related to properties and changes of matter, forms…
