In order to help overcome barriers to success for undergraduate STEM students from disadvantaged backgrounds, we developed two classroom-based research experiences (REs), (CL) and the (SRI). These REs were implemented over a two-year period (2014-2015) for regional community college students as part of the Southern Illinois Bridges to the Baccalaureate (SI Bridges) program. CL and SRI, broadly centered in biomedical sciences research, are designed to be offered in tandem. CL utilizes a guided inquiry approach with microscopy work-stations in experimental cell biology to experientially introduce research while building skills and confidence. CL serves as the gateway experience for the SRI, an intensive summer RE in which scholars engage in authentic research using modern technologies including optogenetics. We piloted the REs in year 1 (9 scholars) and made refinements in year 2 (10 scholars). Participants ("Bridges scholars") were enrolled full-time at one of two regional, rural community colleges, and came on-site to Southern Illinois University at Carbondale (SIUC) for the paid REs. Here we report the development, design and implementation of CL and the SRI, and report improved STEM research-related attitudes and aptitudes as a result of these experiences. Our findings suggest that guided inquiry with increasingly technical authentic research projects in a classroom-based and supportive learning community-style setting is a positive model for the transformation of underserved community college students into confident, motivated scientists with research-ready skills, and is likely translatable to other research novices.

Emotional literacy programme in special schools for children with a learning disability in England: the ZF-SEND feasibility RCT.
Public Health Res (Southampt)
December 2024
School of Psychology, University of Birmingham, Birmingham, UK.
Background: Children with a learning disability experience a range of inequalities and adverse life events that put them at greater risk of mental health problems. The construct of emotional literacy has been shown to be a moderating factor of how life stress affects mental health. Teaching emotional literacy in schools may therefore be an effective way to promote positive mental health.

Objective: There is conflicting evidence whether decreased clerkship duration is associated with reduced NBME shelf examination performance. We hypothesized that scores would remain stable for students in a shortened 2-week flipped classroom-based virtual rotation as compared to the traditional 4-week Neurology clerkship.
Background: There is conflicting evidence whether decreased clerkship duration is associated with reduced NBME shelf examination performance.
Behavioral intentions of university teachers and students toward the adoption of the hyb-blended learning method: Evidence from Bangladesh.

Hyb-blended learning is a novel method that can serve as a substitute for conventional classroom-based learning activities, demonstrating effectiveness in both pandemics like COVID-19 and other crises, as well as in non-pandemic situations. The successful application of this method in the field of education depends on the users' intentions to adopt it. Therefore, this study aims to understand the behavioral intentions of teachers and students at Bangladeshi universities toward the adoption of the hyb-blended learning method.

Department of Psychology, Virginia Commonwealth University, Richmond, VA, USA.
Social media has negative effects on adolescent body image and disordered eating behaviors, yet adolescents are unlikely to discontinue engaging with these platforms. Thus, it is important to identify strategies that can reduce the harms of social media on adolescent mental health. This article reviews research on social media and adolescent body image, and discusses strategies to reduce risks associated with social media use.

CBA has emerged as a prominent pedagogical approach aimed at intertwining assessment within the instructional process, effectively fostering student learning. In English as a Foreign Language (EFL) education, CBA has garnered considerable attention, given its potential to enhance language learners' engagement, speaking proficiency, and willingness to communicate. This mixed-method research study delves into the impact of Classroom-Based Assessment (CBA) on the speaking performance, engagement, and willingness to communicate of undergraduate Chinese EFL learners.
