The high attrition rate among science, technology, engineering, and mathematics (STEM) majors has long been an area of concern for institutions and educational researchers. The transition from introductory to advanced courses has been identified as a particularly “leaky” point along the STEM pipeline, and students who struggle early in an introductory STEM course are predominantly at risk. Peer-tutoring programs offered to all students in a course have been widely found to help STEM students during this critical transition, but hiring a sufficient number of tutors may not be an option for some institutions. As an alternative, this study examines the viability of an optional peer-tutoring program offered to students who are struggling in a large-enrollment, introductory biology course. Struggling students who regularly attended peer tutoring increased exam performance, expert-like perceptions of biology, and course persistence relative to their struggling peers who were not attending the peer-tutoring sessions. The results of this study provide information to instructors who want to design targeted academic assistance for students who are struggling in introductory courses. 相似文献

Statistics are the primary tools for assessing relationships and evaluating study questions. Unfortunately, these tools are often misused, either inadvertently because of ignorance or lack of planning, or conspicuously to achieve a specified result. Data abuses include the incorrect application of statistical tests, lack of transparency and disclosure about decisions that are made, incomplete or incorrect multivariate model building, or exclusion of outliers. Individually, each of these actions may completely invalidate a study, and often studies are victim to more than one offense. Increasingly there are tools and guidance for researchers to look to, including the development of an analysis plan and a series of study specific checklists, in order to prevent or mitigate these offenses.Key words: a priori, analytical plan, statistical methods, disclosure, transparency, biostatistics 相似文献

In the midst of the current environmental crisis, scientists, academics, authors, and politicians worldwide are urging citizens to create sustainable communities. However, there is little capability to build a sustainable society without an informed, active, and engaged populous. This requires more than just environmentally knowledgeable citizens. It requires a society that understands the principles of the environment and can also exemplify them in daily life. In order to create a more environmentally literate world, there has been a push for environmental education integrated into schools. This qualitative study sought to examine Kenyan teachers’ perspectives on the human–nature interaction by conducting vignette focus-group interviews. It is a subject not widely explored but vital for conservation not only in this area, but also other areas that seek to have an ecological informed populous. The vignettes were created using photographs and explanations of the photographs that the participants collected and emailed to the authors. For the focus-group vignette interviews, there were a total of 55 participants (30 females and 25 males). After InVivo analysis, we had 6 codes (resentment, pride, perils, blame, pragmatism, and self-interested) within 3 major themes. This study has implications for informing science education to combat these traditions of subjecting students to a science curriculum that demotes Kenyan cultural heritage and lifestyle. By incorporating local knowledge such as the ideas discussed in this paper into Kenyan science education, Kenyans can reach one of most challenging objectives of education, which is to produce children who are fundamentally aware of their environment. 相似文献

Multiple case study was used to explore the impact of a modeling approach on pre-service teachers’ self-efficacy and willingness to integrate technology into their elementary lessons. Three primary investigators infused educational technology with a range of objectives into teacher education courses. A survey measured student comfort with and understanding of technology. Student products (lesson plans, websites, reflections) and interview responses were analyzed. The analysis revealed that participants gained knowledge and confidence with technology from instructor modeling, but there was a disparity between what pre-service teachers learned in the college classroom and what they experienced in the elementary classrooms. The implications for teacher education programs are discussed. 相似文献

Instructional communication behaviors have been routinely associated with student learning outcomes for the past 40 years; however, the explanations for why these relationships exist remain somewhat controversial. Specifically, the relationship between immediacy and learning outcomes continues to be disputed. This study used Self-Determination Theory to evaluate the utility of students’ need for relatedness and their intrinsic motivation to learn as sequential mediators of the teacher immediacy-student learning relationships. Results of a structural equation model supported the theory’s hypothesis, as relatedness and intrinsic motivation to learn operated in serial to mediate the immediacy-learning relationship. These results indicate Self-Determination Theory is a well-suited framework for explaining the relationship between instructors’ communicative behaviors (e.g., immediacy) and their effects on student outcomes. 相似文献

Extant research has established that racially based brawn and brain frames are common within sports media. Framing theory suggests that these brawn and brain frames should influence audience members’ behaviors and attitudes, but little empirical evidence to support this notion exists. This study used a quasi-experimental design (Frame x Athlete Race) to understand how exposure to sports news articles that emphasize the physical or mental attributes of White and Black athletes may result in audiences’ subsequent observable behaviors or character judgments toward athletes. Results indicated that frames influenced audiences’ behaviors in a simulated environment and attitudes regarding athletes’ mental abilities, whereas athlete race influenced audiences’ attitudes of athletes’ physical abilities. These findings support sports scholars’ assertions about framing effects and underscore the potential dangers of current sports media trends. 相似文献

This paper finds its origins in a multidisciplinary research group’s efforts to assemble a review of research in order to better appreciate how “spatial reasoning” is understood and investigated across academic disciplines. We first collaborated to create a historical map of the development of spatial reasoning across key disciplines over the last century. The map informed the structure of our citation search and oriented an examination of connection across disciplines. Next, we undertook a network analysis that was based on highly cited articles in a broad range of domains. Several connection gaps—that is, apparent blockages, one-way flows, and other limitations on communications among disciplines—were identified in our network analysis, and it was apparent that these connection gaps may be frustrating efforts to understand the conceptual complexity and the educational significance of spatial reasoning. While these gaps occur between the academic disciplines that we evaluated, we selected a few examples for closer analysis. To illustrate how this lack of flow can limit development of the field of mathematics education, we selected cases where it is evident that researchers in mathematics education are not incorporating the important work of mathematicians, psychologists, and neuroscientists—and vice versa. Ultimately, we argue, a more pronounced emphasis on transdisciplinary (versus multidisciplinary or interdisciplinary) research might be timely, and perhaps even necessary, in the evolution of educational research. 相似文献

A growing body of research suggests educators need to focus on cultivating social and emotional competencies that youth will need to thrive in the new knowledge economy (Durlak, Weissberg, Dymnicki, Taylor, &; Schellinger, 2011). For marginalized urban youth, in particular, few have derived programs and interventions to assist with these competencies. This study illuminates the perspectives of 9 African American youth at risk for academic failure taking part in the Fulfill the Dream (FTD) program. FTD is a social and emotional learning curriculum emphasizing social justice and critical consciousness through the utilization of hip-hop culture. Information regarding the nature of the collaboration of this research project and recommendations for education professionals working with marginalized youth are discussed. 相似文献

The purpose of this study was to identify the various ways that instructors communicatively fulfill college students’ basic psychological needs (i.e. autonomy, competence, relatedness) in the classroom. Participants were 119 undergraduate students who completed open-ended, self-report questionnaires. Analyses of the coded data revealed that a variety of instructor communication behaviors and practices previously identified in the effective teaching literature fulfill students’ needs for autonomy, competence, and relatedness. According to Deci and Ryan’s (1985) self-determination theory, the fulfillment of these needs intrinsically motivates students to learn, develops their cognitive capacities, and equips them for short-term and long-term success. 相似文献
