Schools throughout the United States use the IQ-achievement discrepancy method to

identify children with learning disabilities. This current method allows many students to fall behind in the regular education setting. In 2004, the Individuals with Disabilities Education Act was reauthorized to provide states with the option of using a response to intervention (RtI) model in lieu of or in conjunction with the IQ-achievement discrepancy model. The purpose of this quasi-experimental, single subject, pre/posttest design study was to determine the impact of a Tier II intervention using SuccesMakers Math, a learning system that adapts to the unique needs of the individual …

Restructuring High School Science Curriculum: A Program Evaluation, Cathy Robertson

Walden Dissertations and Doctoral Studies

One rural Midwestern high school discovered a discrepancy among school, state, and national science skill attainment, verified by ACT scores. If students do not acquire vital science skills, they may not perform proficiently on science tests, thus impacting future college options. Inquiry based instruction and constructivism provided the basis for the theoretical framework. This study questioned associations between ACT scores, inquiry science technique usage, and ACT standard usage (Phase 1), and teachers' views on science instruction (Phase 2). This sequential explanatory mixed methods program evaluation included 469 ACT scores, surveys sent to 9 science teachers, and 8 interviews. Phase 1 …

Implementation Of The Environmental Issues Instruction Model By Elementary Teachers, Barbara Ann Ehlers

Dissertations and Theses @ UNI

Teachers attend many professional development experiences throughout their professional careers. Many teachers attend because they have a personal desire for professional growth. In addition, in the state of Iowa, they are required to engage in professional development to renew teacher licensure. Professional development is offered on a myriad of topics including the latest educational research on learning, innovations in curriculum, and instructional strategies to use in the classroom. However, just attending does not guarantee improved professional practice. After these experiences teachers may or may not implement the strategies, teaching methods, or information they have learned.

This qualitative study analyzed data …

Educational Leadership & Workforce Development Faculty Publications

There is a strong need to increase the number of undergraduate students who pursue careers in science to provide the “fuel” that will power a science and technology–driven U.S. economy. Prior research suggests that both evidence-based teaching methods and early undergraduate research experiences may help to increase retention rates in the sciences. In this study, we examined the effect of a program that included 1) a Summer enrichment 2-wk minicourse and 2) an authentic Fall research course, both of which were designed specifically to support students' science motivation. Undergraduates who participated in the pharmacology-based enrichment program significantly improved their knowledge …

Teaching High School Biology Students To Coordinate Text And Diagrams: Relations With Transfer, Effort, And Spatial Skill, Bradley W. Bergey, Jennifer G. Cromley, Nora S. Newcombe

Publications and Research

There is growing evidence that targeted instruction can improve diagram comprehension, yet one of the skills identified in the diagram comprehension literature—coordinating multiple representations —has rarely been directly taught to students and tested as a classroom intervention. We created a Coordinating Multiple Representation (CMR) intervention that was an addition to an intervention focused on Conventions of Diagrams (COD) and tested their joint effects on diagram comprehension for near transfer (uninstructed biology diagrams), far transfer (uninstructed geology diagrams), and content learning (biology knowledge). The comparison group received instruction using a previously validated intervention that focused exclusively on COD. Participants were 9th–10th …
