The use of online platforms in higher education as an alternative to traditional residential classrooms has grown dramatically in recent years. The integration of online technology into pedagogy technology is acknowledged as a useful means for addressing the characteristics of Generation Z, an age cohort for which technology is second nature. This chapter examines the efficacy of the use of audio recordings as an additional pedagogical tool for engaging students in both active learning and information dissemination on career opportunities and methods for career advancement. Specifically, the chapter reports on a case study in which active learning was employed in an online course – Retail Management – an undergraduate elective course taught in the marketing major at a large public institution. Audio recordings, labeled “Professionals on Demand (PODcasts)” were used to provide insights into career explorations, job searching, and networking. To conclude, directions for future teaching practice and research are provided.

Do It Yourself

Since its introduction in the early 2000s, podcasting has become a popular alternative to traditional radio, with a do-it-yourself emphasis and a democratization of producing audio without a need for advertisers or a broadcaster’s backing. Podcasting has also been a promising learning tool for educators and students. With the popularity of the platform, many have jumped on board to create and utilize podcasts for pedagogical purposes, both in the classroom and for the public. Podcasting for pedagogical purposes has coincided with developments in educational theory such as flipped classrooms, active learning, and digital humanities. While there have been debates about the effectiveness of using podcasts for educational purposes, the majority of the literature on podcasting demonstrates that there are benefits for students learning through podcasts and digital audio recordings. Whether it’s the positives and the negatives of the format, or even just how to create a podcast, literature on podcasting has grown exponentially as more people and scholars think about how to use the medium for learning purposes. One significant hurdle in terms of a creating a podcasting bibliography is that the technology involved has changed over the years since its introduction to academia. While some of the methodology may not be as up-to-date in the older texts, they still have critical information that is relevant to incorporating podcasting into a classroom setting.

Labeling of samples is a recurrent and time-consuming task in data analysis and machine learning and yet generally overlooked in terms of visual analytics approaches to improve the process. As the number of tailored applications of learning models increases, it is crucial that more effective approaches to labeling are developed. In this paper, we report the development of a methodology and a framework to support labeling, with an application case as background. The methodology performs visual active learning and label propagation with 2D embeddings as layouts to achieve faster and interactive labeling of samples. The framework is realized through SoundscapeX, a tool to support labeling in soundscape ecology data. We have applied the framework to a set of audio recordings collected for a Long Term Ecological Research Project in the Cantareira-Mantiqueira Corridor (LTER CCM), localized in the transition between northeastern São Paulo state and southern Minas Gerais state in Brazil. We employed a pre-label data set of groups of animals to test the efficacy of the approach. The results showed the best accuracy at 94.58% in the prediction of labeling for birds and insects; and 91.09% for the prediction of the sound event as frogs and insects.

Reported Data

Substantial evidence suggests active learning pedagogies are superior to lecturing, but little evidence exists on the prevalence of such methods. Watts and Schaur (2011) find, based on self-reported data, the median instructor lectures 83 percent of the time. We analyze audio recordings of 535 total classes from 30 different instructors to show instructors greatly underestimate how often they use passive learning pedagogies such as lecturing. Survey results show instructors estimate they lecture approximately 78.5 percent of class time; our data reveals the true average is 89 percent. This gap between perception and reality is statistically significant.

AbstractThe occurrence of LDE-type flares in the last three cycles has been investigated. The Fourier analysis spectrum was calculated for the time series of the LDE-type flare occurrence during the 20-th, the 21-st and the rising part of the 22-nd cycle. LDE-type flares (Long Duration Events in SXR) are associated with the interplanetary protons (SEP and STIP as well), energized coronal archs and radio type IV emission. Generally, in all the cycles considered, LDE-type flares mainly originated during a 6-year interval of the respective cycle (2 years before and 4 years after the sunspot cycle maximum). The following significant periodicities were found:• in the 20-th cycle: 1.4, 2.1, 2.9, 4.0, 10.7 and 54.2 of month,• in the 21-st cycle: 1.2, 1.6, 2.8, 4.9, 7.8 and 44.5 of month,• in the 22-nd cycle, till March 1992: 1.4, 1.8, 2.4, 7.2, 8.7, 11.8 and 29.1 of month,• in all interval (1969-1992):a)the longer periodicities: 232.1, 121.1 (the dominant at 10.1 of year), 80.7, 61.9 and 25.6 of month,b)the shorter periodicities: 4.7, 5.0, 6.8, 7.9, 9.1, 15.8 and 20.4 of month.Fourier analysis of the LDE-type flare index (FI) yields significant peaks at 2.3 - 2.9 months and 4.2 - 4.9 months. These short periodicities correspond remarkably in the all three last solar cycles. The larger periodicities are different in respective cycles.
