University Interdisciplinary Linked Block Schedules And Developmental Student Success, Linda S. Reeves-Wymer Jan 2023

University Interdisciplinary Linked Block Schedules And Developmental Student Success, Linda S. Reeves-Wymer

Walden Dissertations and Doctoral Studies

Developmental education is the starting point for many 1st-year college students, especially from underrepresented, low-income, and first-generation populations. One such 1st-year program linked block-scheduled academic skill-development courses with a required interdisciplinary general education science course where instruction was provided simultaneously in a lecture format to college-ready nondevelopmental students and developmental students in three skill-development courses: reading, writing, and combined reading/writing. Although this program had existed for over 20 years, the effectiveness of the program, meaning whether the linked skill-development courses were associated with academic success, had not been assessed.

The Interrelationship Between Sensorimotor Deficits And Maladaptive Behavior In The Classroom, L B Marie Filion

Walden Dissertations and Doctoral Studies

Mainstreaming special education students has created challenges for teachers, resulting in significant lesson time allocated to classroom disruptions related to maladaptive behavior. This correlational study examined the extent to which specific sensorimotor deficits predict maladaptive behavior among special education students (aged 8-12 years) based on archival data of teacher assessments in New Zealand. Piaget’s cognitive and affective development theory was used as the theoretical foundation. Results from standard multiple regression demonstrated that higher levels of sensorimotor deficits (vision, touch, taste and smell, body awareness, balance and motion) predicted high levels of maladaptive behavior (internalizing, externalizing, and overall maladaptive behavior indices); …
