The professional identity of scientists has historically been cultivated to value research over teaching, which can undermine initiatives that aim to reform science education. Course-Based Research Experiences (CRE) and the inclusive Research and Education Communities (iREC) are two successful and impactful reform efforts that integrate research and teaching. The aim of this study is to explicate the professional identity of instructors who implement a CRE within an established iREC and to explore how this identity contributes to the success of these programs.

- Over two decades, initiatives have aimed to enhance STEM undergraduate outcomes, with the inclusive Research Education Community (iREC) emerging as a scalable reform model that supports STEM faculty in implementing course-based research to improve student learning.
- This study utilized pathway modeling to describe the HHMI Science Education Alliance (SEA) iREC, identifying how faculty engagement leads to sustainable adoption and improvement of new teaching strategies through feedback from over 100 participating faculty members.
- The findings indicate that iREC fosters a collaborative environment where STEM faculty can share expertise and data, thereby enhancing their teaching practices and contributing to the overall evolution of undergraduate science education.
Models of Classroom Assessment for Course-Based Research Experiences.

Course-based research pedagogy involves positioning students as contributors to authentic research projects as part of an engaging educational experience that promotes their learning and persistence in science. To develop a model for assessing and grading students engaged in this type of learning experience, the assessment aims and practices of a community of experienced course-based research instructors were collected and analyzed. This approach defines four aims of course-based research assessment - 1) Assessing Laboratory Work and Scientific Thinking; 2) Evaluating Mastery of Concepts, Quantitative Thinking and Skills; 3) Appraising Forms of Scientific Communication; and 4) Metacognition of Learning - along with a set of practices for each aim.

- - The study investigates the implementation and educational benefits of course-based research experiences (CRE) in STEM education over three years, involving 102 instructors from the SEA-PHAGES program.
- - The research includes surveys and feedback sessions to understand instructors' perspectives on the goals and teaching practices of CRE, ultimately utilizing qualitative content analysis.
- - Findings reveal three instructional models for CRE teaching: 1) acting as a scientist and generating data, 2) teaching procedural knowledge, and 3) promoting project ownership, which help inform new instructors and institutions about effective CRE instruction.
Electrical stimulation of contractions (pacing) of primary neonatal rat ventricular myocytes increases intracellular calcium and activates a hypertrophic growth program that includes expression of the cardiac-specific gene, atrial natriuretic factor (ANF). To investigate the mechanism whereby pacing increases ANF, pacing was tested for its ability to regulate mitogen-activated protein kinase family members, ANF promoter activity, and the trans-activation domain of the transcription factor, Sp1. Pacing and the calcium channel agonist BAYK 8644 activated c-Jun N-terminal kinase (JNK) but not extracellular signal-regulated kinase.
