Piloting a Blended Approach to Teaching Statistics in a College of Education: Lessons Learned

This study investigated the performance of graduate students enrolled in introductory statistics courses. The course in Fall 2005 was delivered in a traditional face-to-face manner and the same course in Fall 2006 was blended by using an online commercial tutoring system (ALEKS) and making attendance of several face-to-face classes optional. There was no significant difference in the t-test comparing performance in the courses, which used the students’ combined score on two mid-terms and the final exam to indicate performance. The ANCOVA analyzing influences on performance in the blended class yielded no significant influence for gender, ethnicity, age, or class type (traditional vs. blended), but a significant influence from students’ incoming GREQuantitative score. Seven Likert questions on students’ perception of blended learning were not correlated with student performance. Three focus groups – comprised of low-, medium-, and high-performing students – revealed three themes and several subthemes and differences based on students’ performance level.

The Experience and Persistence of College Students in STEM Majors

In this study, an online survey was constructed based on the extant literature on college student success. The survey was used to collect data from a sample of college students in science, technology, engineering, and math (STEM) majors in order to examine their learning experiences and to identify the factors that may influence their persistence to degree completion. The findings support the theoretical modeling of the academic and social aspects of student college experience. Nonetheless, it is the institutional conditions, particularly the quality of academic program and faculty teaching and accessibility, which dominate the STEM students’ college experience and their persistence in academic major and to graduation. Therefore, it is critical for academic institutions to invest in a supportive learning environment by emphasizing quality teaching, accessible academic advising, and related functions in order to successfully engage STEM students in college education and increase their likelihood of degree completion.

College Student Retention on a Racially Diverse Campus: A Theoretically Guided Reality Check.

Theoretically grounded in Tinto’s model of retention and Braxton and colleagues’ revisions , this study is designed to examine the applicability of the integration model to students of different racial backgrounds. Results from a sample of full-time undergraduate students at a research-extensive university suggest that (a) academic and social integrations function differently to the persistence of Black and White students, (b) financial pressure was the most consistent impediment to college retention for all students, and (c) institutional control over academic quality is critical to student retention. In addition, results show that students of different racial backgrounds do not differ significantly in their reported intention to drop out. Implications for policy and planning are discussed.
