Measuring the Acceleration of Falling Objects

Earth\u27s gravity pulls all objects toward its center, and near the Earth\u27s surface. Objects in free fall accelerate at 9.8 m/s2 vertically downward, provided air resistance is negligible. This value of acceleration is often referred to as g . There are many ways to measure this rate of acceleration, and most require a timing device. Typically, stopwatches are the least expensive technology, so these are commonly available in high school science classrooms. With the recent addition of movie cameras on cell phones and digital cameras, another timing tool is available at moderate cost (free if the school policy allows students to use their personal cell phones during class time). The following set of experiments provide four ways to calculate g using (1) a 10-meter (25-yard) tape measure, (2) a brightly colored ball, (3) a stop watch, (4) a digital camera with movie mode, (5) a tripod, and (6) free software called MovieTracker (http://www.lawrencehallofscience.org/gss/rev/ip/index.html)

Factor analysis of the Brain Check Survey

2013 Summer.Includes bibliographical references.Children who have a traumatic brain injury (TBI) are under-identified and lack appropriate educational supports to help them achieve their academic goals. Because TBI can greatly impact a child's ability to succeed at school, there is a need for a convenient and effective way to screen for TBI in students who are struggling in school so they can obtain appropriate school-based services. The purpose of this study was to work toward establishing construct validity for the Brain Check Survey (BCS), which is a parent-report questionnaire intended to help school personnel screen for possible TBI in students. The BCS can act as a starting point in the process of qualifying students for Special Education, a 504 Plan, or Response to Intervention assistance. In five different school districts in Colorado, parents completed the BCS for their child who was recruited from one of three groups: has identified TBI, is currently receiving special education services for diagnosed specific learning disabilities, or is considered typically developing. Construct validity was tested using multiple factor analyses: 1) all participants combined (typically developing, traumatic brain injury, and specific learning disability), 2) elementary, middle, and high school level categories of all participants, and 3) all ages from the typically developing group only. These factor analyses confirmed the two-factor construct of the BCS that measures student Symptoms and Behaviors. The analysis also gave insight into two distinct aspects of behaviors that the instrument is measuring: Cognitive Processing and Behavior Control. The positive findings from this factor analysis study suggest that the BCS has strong construct validity and can be effective in screening students for possible TBI

How Can Researchers\u27 Browsing Behaviors Inform Library Space-Planning?

This study is an in-depth, qualitative analysis of the ways academics at the Claremont Colleges browse library materials, both print and electronic, for their research. Many academic libraries today are struggling with the question of how best to accommodate the quantity of print materials they routinely acquire as those volumes increasingly strain the capacity of their physical spaces. It is hoped this project will help these institutions identify which subject-based collections and which format types researchers need to have immediately accessible for physical perusal and which they can browse productively online

Teaching: An Exploration of Best Practices

The purpose of this Action Research Project as part of the fulfillment of my Master of Arts in Teaching degree is to become aware of my teaching practices and to explore options and avenues to better improve my teaching practices. To build a foundation of understanding of teaching practices I first began researching three major themes: effective teaching, evidence-based practices, and developing stronger readers in an ELA classroom; I also sought examples of how I could implement them into my practice . The research begins with an examination of what differentiation is and how it can be modeled. Three sub-themes emerged: designing differentiation, supporting English Language Learners, and how to create inclusive classrooms. Second, my research focuses on identifying the major theme of evidence-based practices by focusing on three sub-themes: high leverage practices, effective instruction in the ELA classroom, and how to create student-centered classrooms. Lastly, because I know that reading is usually a strong indicator for student ability in an ELA classroom, I sought out ways to help develop students into stronger readers. The three sub-themes that arose from this research were using literature circles, technology, and reading identity. I gathered data from my year of student teaching including my teaching journals, lesson plans, lesson materials such as slides or assignments and directions, and teaching observation summaries. Using this data, I analyzed my teaching practices, noting where I had room for growth or had met some of my goals
