Supporting Middle School Students In Tier 2 Math Labs: Instructional Strategies, Emily C. Bouck, Jiyoon Park, Mary Bouck, Jim Alspaugh, Stacey Spitzley, Angela Buckland

Current Issues in Middle Level Education

Response to Intervention (RtI) has become a common support system for students; yet, no universal RtI model exists, especially for mathematics and specifically at the middle school level. This article focuses on a specific model for delivering Tier 2 mathematics supports and services at the middle school level: math labs. Evidence–based and research–supported interventions are discussed that support the delivery of Tier 2 services within a middle school math lab RtI structure. A fictionalized vignette, drawing from multiple actual cases, is presented to highlight the use of a Tier 2 math lab within a middle school setting.

A "Choose-Your-Own" Classroom-Based Activity That Promotes Scientific Inquiry About Rna Interference, Jeremy L. Hsu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

RNA interference (RNAi), the process that results in the degradation of a target gene’s mRNA, is a fundamental part of eukaryotic gene regulation and is also an important molecular technique that allows for experimental manipulation of gene expression without altering DNA sequences. Despite the importance of RNAi, there have been relatively few lecture-based activities designed to teach about the consequences of this process and counter common misconceptions. I present here an inquiry-based activity that is centered around a “choose your own experiment” design where students generate hypotheses and critically evaluate their ideas by choosing several simulated experiments. The activity presents …

Promoting Stem Teacher Reflection Through Self-Evaluation, Steven W. Mumford, Kathryn Newcomer

Political Science Faculty Publications

Evaluators face serious challenges assessing the impact of teaching practice on student outcomes, such as for assessing the impact of grant-funded teacher training programs. To overcome these barriers, the evaluators of an NSF-funded teacher scholarship program elected to coach teachers on conducting their own evaluations of student outcomes. To facilitate this process, we collaboratively developed templates and guidance for teachers’ measurement and reporting of student growth, provided training and technical assistance as teachers prepared student outcome data, and guided teachers in reflecting on results to improve their practice. The evaluators then aggregated fellows’ student outcome reports to assess the program’s …

A Mixed-Methods Study Of Entomology Incorporation In U.S. Secondary Science Instruction, Erin M. Ingram

Department of Entomology: Dissertations, Theses, and Student Research

To encourage understanding and appreciation of insects, entomology education advocates have supported and encouraged K-12 teachers to integrate insects and insect-related content into formal science instruction. However, research examining how and why science teachers incorporate entomology into secondary science courses is limited.

A sequential explanatory mixed-methods research study was conducted to address this gap. The study was conducted in two phases. During the first phase, quantitative survey research was conducted with a representative sample of 254 U.S. secondary life science teachers. During the subsequent qualitative phase, follow-up interviews were conducted with a purposeful sample of 18 survey participants and an …
