Hubble space telescope: Pointing error effects on nonlinear ball joints

The Hubble Space Telescope pointing error produced by optical benches mounted on free ball joints is examined. Spacecraft cable connections are assumed to produce translational and rotational damping and restoring forces which act through the optical bench center of mass. The nonlinear dynamics are modeled and then implemented using an existing computer program for simulating the vehicle dynamics and pointing control system algorithm. Results are presented for the test case which indicate acceptable performance

Institutionalizing TILT Across a University

Transparency of learning and teaching (TILT) is key to student success, as it allows students to understand directions and make concrete steps toward completing a set of tasks. The present paper outlines the early stages of a campus-wide program at one institution that infuses TILT practices across campus in the classroom as well as non-academic units. TILT practices make the purpose, required tasks, and criteria for success clear to students in everyday campus interactions with faculty and staff. TILT programming for faculty and staff is described, including strengths, challenges, and future directions

Quality and Cost Matter: Students’ Perceptions of Open versus Non-Open Texts through a Single-Blind Review

Although prior research has examined student perceptions of open materials, research investigating students’ perceptions of open versus copyright-restricted textbooks through a direct, experimental approach is lacking. To better understand how students perceive open textbooks outside the context of the classroom, we examined students’ perceptions of unfamiliar open and non-open (copyright-restricted) psychology textbooks. Forty-four introductory psychology students reviewed chapters from two open textbooks and two traditional/copyrightrestricted textbooks and then ranked the textbooks from most to least favourite. Students rated each chapter on several quality measures, including layout structure, visual appeal, ease of reading, and instructional features. Next, bibliographical information and cost were revealed, and students re-ranked the textbooks accordingly. Before knowing the bibliographic information and cost, students were more likely to prefer the two traditional textbooks. There after, they were more likely to select the open texts. Students often referred to textbook price as a determining factor for their change

Open-Educational Resources (OERs) in the College Classroom: A Case Study

Rising textbook costs are creating additional debt for college students and in some cases, are causing students to forgo purchasing a textbook (Mitchell, 2014). Open educational resources (OER), which are typically free or low-cost, have become an increasingly popular alternative to traditional paper textbooks. In this study, we examined perceptions and effectiveness of an OER in an introductory psychology course at a small, public university in Georgia. We compared 1) perceptions of the type of textbook students were using (perceptions of OERs among students using an OER and traditional paper texts among students using traditional paper texts) and 2) course performance (i.e., exam grades). First, we found that students preferred the textbook format they were given: Students who used the OER preferred using the OER to a traditional paper text, and students using a traditional paper text preferred using a paper text. Second we compared exam grades across the two courses. Although initial differences were found, these differences were not statistically significant, t(64) = -1.329, p = 1.88. This presentation is based on a completed research project. Implications for using OER in all disciplines will be discussed
