In the world of K–12 education, the growing numbers of dropouts are a major concern. This article examines the dropout rates of Chinese and Vietnamese high school students. Using logistic regression analysis, this article examines the influence of ethnicity, gender, and socioeconomic status (SES) on dropout rates. The distinct contribution of this analysis lies within the intraethnic comparisons within the Asian American student population and its use of longitudinal data. The results of the study support existing research that gender and SES are related to dropout rates. Moreover, an interesting interaction between ethnicity and SES exists.

This work proposes a procedure for simultaneous parameters identifiability and estimation in metabolic networks in order to overcome difficulties associated with lack of experimental data and large number of parameters, a common scenario in the modeling of such systems. As case study, the complex real problem of parameters identifiability of theEscherichia coliK-12 W3110 dynamic model was investigated, composed by 18 differential ordinary equations and 35 kinetic rates, containing 125 parameters. With the procedure, model fit was improved for most of the measured metabolites, achieving 58 parameters estimated, including 5 unknown initial conditions. The results indicate that simultaneous parameters identifiability and estimation approach in metabolic networks is appealing, since model fit to the most of measured metabolites was possible even when important measures of intracellular metabolites and good initial estimates of parameters are not available.

The development of student civic engagement has featured in Indian educational policies for decades as a critical goal of schooling. However, the narrowness of the prescribed K-12 curricula, and the intense focus on competitive exams, do not support such an outcome. To overcome this problem, ABC School in India decided to pilot service-learning in its middle-school classroom. The idea was to assess the effects of such a program on students and the community’s welfare. Analysis of data from surveys, focus groups, and interviews showed that the service-learning project might have supported increased civic engagement in some students while also enhancing the welfare of the community served. No prior peer-reviewed empirical studies have been published on the nature and effects of service-learning at schools in India.

<p>A recent phenomenon in the MOOC space has been the development of courses tailored to educators serving in K-12 settings. MOOCs, particularly as a form of educator professional development, face a number of challenges. Academics, as well as pundits from traditional and new media, have raised a number of concerns about MOOCs, including the lack of instructional and social supports. It is an assumption of this study that challenges arising form this problem of scale can be addressed by leveraging these massive numbers to develop robust online learning communities. This mixed-methods case study addresses critical gaps in the literature and issues of peer support in MOOCs through an examination of the characteristics, mechanisms, and outcomes of peer networks. Findings from this study demonstrate that even with technology as basic as a discussion forum, MOOCs can be leveraged to foster these networks and facilitate peer-supported learning. Although this study was limited to two unique cases along the wide spectrum of MOOCs, the methods applied provide other researchers with an approach for better understanding the dynamic process of peer supported learning in MOOCs.</p>

In this case study, undergraduate students presented physics concepts to patrons at a planetarium. This created an early opportunity for these pre-professionals to practice the process skill of oral communication to a lay audience. The case study resulted from working with students participating in a grant called the da Vinci project. It reports on a situated experience pre-engineering and calculus-based physics students had working with their professor to create a brochure and present a physics concept to patrons visiting a public planetarium. Working closely with their professor, students were able to use this required professional skill in a real world (situated) context. This opportunity helped bridge the gap between these pre-professionals’ experiences in training and in their careers in STEM fields. Thirty students attending a two-year college in the Southwestern US self-selected to participate in the project. Each student participant built a kit-based model of a machine, designed an informational flyer aligned to state K-12 physical science standards, and presented informally to the public visiting a planetarium. Data were collected from the students via written reflections before and after the presentation and from email correspondence with their professor. Qualitative analyses of these reflections assessed the students’ progress toward a finished presentation. Results suggest that obstacles to public speaking fluency come from the fear of making mistakes or giving out misinformation. Opportunities to engage in informal public speaking helped overcome these obstacles. Students demonstrated increased confidence in their ability to share their knowledge with the public after undergoing guided informal speaking practice. The opportunity for students to practice public speaking during their undergraduate training can increase confidence and better prepare them for a career.
