Perturbations Observed In The Orbital Elements Of The Spectroscopic Binary 57 Cygni, Kenneth W. Mclaughlin, Janak Panthi

Journal of the Iowa Academy of Science: JIAS

We present spectroscopy that confirms periodic Doppler-shifts along with photometry that reinforces a lack of eclipsing in the double-lined spectroscopic binary 57 Cygni. Our spectroscopy concentrates on a range encompassing H-alpha and the helium 667.8 nm line, where we find Doppler-shifts of both stars resolved in the helium line but less so in the broader H-alpha profile. Although we find the radial velocities derived from both lines reasonably consistent, we retained only the helium-line derived velocities for sinusoidal curve-fits to the orbital dependence. The fit-amplitudes specify the ratio of the stellar masses as 1.03 ± 0.05, in agreement with previous …

The Effects Of Teaching Exponential Functions Using Authentic Problem Solving On Students’ Achievement And Attitude, Yamamah Sawalha

Wayne State University Dissertations

Most of the current mathematics education focuses on procedures and pays very little attention to conceptual understanding in many classrooms. NCTM (2000) called for improving students’ understanding to help improve their achievement. To help prepare students for the future, they need to be taught to value mathematics and realize that it is relevant to their lives. Students need to use their mathematical knowledge to solve real life problems. This can’t be achieved by focusing only on the procedures and expecting students to understand how to apply it to real life. The purpose of this study was to examine the effect …

Effect Of Technology On Community College Developmental Mathematics Course Completion Rates, Mandi Leigh Bradford

Walden Dissertations and Doctoral Studies

Students who enter community colleges in need of developmental education are often at high risk of failure due to identities or perceptions of self, that do not conform to college expectations that can be problematized by age, gender, and ethnicity. Additionally, students' efficacy for using technology may affect completion rates which was examined at Midwest Community College (MCC) through observing a program shifting from teacher-directed course designs with greater teacher-student interaction to technology-directed course designs with greater technology-student interactions. The theoretical foundation of this study was Tinto's theory of student retention based on the belief that student success is facilitated …
