Distortion or Clarification: Defining Highly Qualified Teachers and the Relationship between Certification and Achievement

Recent studies of the relationship between teacher preparation pathways and student achievement have resulted in similar statistics but contradictory conclusions. These studies as a group have several limits: they sometimes focus on student-level indicators when many policy decisions are made with indicators at the school-level or above, are limited to specific urban locations or grade levels, or neglect the potential influence of building type, as defined as the grade-levels serviced. Using statewide data from the 2004-2005 school year, we examined the relationships between school-level indicators of student achievement on nationally-normed tests and proportions of alternatively certified teachers, while controlling for building type and other relevant covariates. Our findings indicate that the relationship between teacher preparation and student achievement at the school level depends on whether the building mixes multiple grade levels (e.g., elementary and middle). The implications of Missouri's policy change for research and school improvement are discussed with respect to the current high-stakes testing environment

College Student Retention : Formula for Student Success

2e éditionComprend des références bibliographiques et un indexAlthough access to higher education is virtually universally available, college student retention stills remains a vexing and puzzling problem for educators and legislators. In College Student Retention: Formula for Student Success, second edition, Alan Seidman deals with this problematic issue by examining a number of areas critical to the retention of students, including the history, the theories and concepts, models, and a standardized definition of the term. Seidman and his contributors also lay out the financial implications and trends of retention in one of their updated chapters. Completely new to this edition are three chapters that examine several recent issues: the current theories of retention, retention of online students, and retention in community colleges. Tying all of these components together, Seidman then presents his formula and highly successful model for student success that colleges can implement to effect change in retaining students and helping them to complete their academic and personal goals.Chapter 1: Past to Present: A Historical Look at Retention ; Chapter 2: Measurements of Persistence ; Chapter 3: Retention Theories, Models and Concepts ; Chapter 4: How to Define Retention: A New Look at an Old Problem ; Chapter 5: Finances and Retention: Trends and Inplications ; Chapter 6: Pre-College and Institutional Influences on Degree Attainment ; Chapter 7: Community College Retention ; Chapter 8: Pathways to a Four-Year Degree: Determinants of Transfer and Degree Completion ; Chapter 9: On-line Student Retention ; Chapter 10: Student Persistence and Defree Attainment Beyond the First Year in College ; Chapter 11: Moving From Theory to Action ; Chapter 12: Taking Action: A Formula and Model for Student Succes
