Facilitating Student Engagement In Elementary Science Classrooms With Reformed Teaching Principles, Nathaniel Bryant

Dissertations and Theses @ UNI

Science performance among elementary school students in the United States has stagnated in recent years. To address this issue, the Next Generation Science Standards (NGSS) were introduced, advocating for a reform in science education. Traditionally, hands-on laboratory work has been used to help students understand scientific concepts through a "learn by doing" approach. However, students often become disengaged during practical work, as following a set procedure to replicate scientific phenomena does not reflect how scientists approach problems in their daily practice. It is now argued that hands-on laboratories should not only involve observation or manipulation of materials and equipment but …

Faculty, Staff and Students Publications

Patients with immune dysregulation may present with varying combinations of autoimmunity, autoinflammation, immunodeficiency, atopy, lymphoproliferation, and/or malignancy, often with multisystem involvement. Recognizing specific patterns of immune dysregulation, coordinating and interpreting complex diagnostic testing, and choosing initial (often empiric) treatment can be challenging. Centers are increasingly assembling multidisciplinary teams (MDTs) to standardize evaluation and optimize treatment of patients with complex immune dysregulation (immune dysregulation MDTs [immMDTs]). However, published information on the composition and function of immMDTs is sparse, and there is little guidance for those seeking to establish or optimize an immMDT. To inform this review, we assembled a panel of …
