As educational budgets continue to shrink, colleges and universities have turned to online course delivery as a means of increasing enrollments. In addition, with the proliferation of Internet-based course management and other software that facilitate the learning experience, many traditional courses are adding an online component, creating hybrid courses in different formats. In this chapter, the authors explore different strategies and technology solutions to help instructors develop rich, dynamic courses, whether they are completely online or hybrid courses that use online tools and technologies to augment the traditional class. This chapter covers the advantages and disadvantages of hybrid courses, technologies and practices available for them, emerging technologies such as Second Life™, social networks, dense wavelength division multiplexing, telepresence, satellite networks, and the use of texting in the classroom.

The Relationship

Purpose – This paper aims to investigate the relationship between hybrid classes (where a per cent of the class meetings are online) and transportation-related CO2 emissions at a commuter campus similar to San José State University (SJSU). Design/methodology/approach – A computer model was developed to calculate the number of trips to campus for a student body similar to SJSU. Different scenarios considered the theoretical effectiveness of implementing a hybrid course system to reduce CO2 emissions. Findings – Increases in hybrid courses resulted in decreased student trips to campus and associated CO2 emissions. The utility of such a relationship is demonstrated through a case study where the required increase in online class meetings needed to eliminate the need for an overflow parking lot is studied. Finally, preferential scheduling of online meetings can further reduce trips to campus. Research limitations/implications – A limitation of the model is that student schedules are random. Future research could use actual student schedules to better model how online course delivery will affect trips to campus. Practical implications – As today’s universities struggle with financial pressure, online course delivery is being offered as a way to cope. This analysis provides an additional metric to evaluate online courses and includes other potential financial savings. Social implications – Transportation contributes to local air pollution and emissions of heat-trapping gases. As universities move toward more sustainable behaviors, reducing automobile trips to campus can be seen as a priority. Originality/value – To the authors’ knowledge, this is the first attempt to model the relationship between hybrid courses and CO2 emissions at an urban university. This information will be valuable to the SJSU community, as well as many other institutions.

The purpose of this study was to evaluate student perceptions of different online course delivery methods. In order to develop the experimental course delivery method, the researchers used universal design for learning (UDL) guidelines as a theoretical framework. Responses to pre- and postsurvey items provided data to examine whether an online course developed using UDL principles afforded a more positive learning experience. This study provides online student perceptions that indicate the online learning environment developed with the UDL framework is preferred by students.

AbstractData rates in optical fiber networks have increased exponentially over the past decades and core-networks are expected to operate in the peta-bit-per-second regime by 2030. As current single-mode fiber-based transmission systems are reaching their capacity limits, space-division multiplexing has been investigated as a means to increase the per-fiber capacity. Of all space-division multiplexing fibers proposed to date, multi-mode fibers have the highest spatial channel density, as signals traveling in orthogonal fiber modes share the same fiber-core. By combining a high mode-count multi-mode fiber with wideband wavelength-division multiplexing, we report a peta-bit-per-second class transmission demonstration in multi-mode fibers. This was enabled by combining three key technologies: a wideband optical comb-based transmitter to generate highly spectral efficient 64-quadrature-amplitude modulated signals between 1528 nm and 1610 nm wavelength, a broadband mode-multiplexer, based on multi-plane light conversion, and a 15-mode multi-mode fiber with optimized transmission characteristics for wideband operation.

AbstractIn this work, we study and analyze the performance of Raman + Erbium-Ytterbium codoped fiber hybrid optical amplifier (HOA) for an ultradense wavelength division multiplexing (UD-WDM) system having 100 channels. The system has been investigated considering initial values of channel spacing and data rate of 0.1 nm (12.5 GHz) and 100 GB/s, respectively. Initially, the two important WDM system parameters—wavelength and channel spacing—have been selected and then optimization of the proposed HOA has been performed in terms of EYDFA length, pump power and Er+ concentration to achieve higher values of average gain, Q-factor and lower gain variation ratio. The optimized configuration of the HOA results in the achievement of higher value of average gain, Q-factor and gain variation ratio of 47 dB, 14 and 0.14, respectively, which confirms its viability for UD-WDM system applications.
