Engaging farmers as citizen scientists may be a cost-efficient way to answering applied research questions aimed at more sustainable land use. We used a citizen science approach with German horse farmers with a dual goal. Firstly, we tested the practicability of this approach for answering ‘real-life’ questions in variable agricultural land-use systems. Secondly, we were interested in the knowledge it can provide about locomotion of horses on pasture and the management factors influencing this behaviour. Out of 165 volunteers, we selected 40 participants to record locomotion of two horses on pasture and provide information on their horse husbandry and pasture management. We obtained complete records for three recording days per horse from 28 participants, resulting in a dataset on more individual horses than any other Global Positioning System study published in the last 30 years. Time spent walking was greatest for horses kept in box-stall stables, and walking distance decreased with increasing grazing time. This suggests that restrictions in pasture access may increase stress on grass swards through running and trampling, severely challenging sustainable pasture management. Our study, involving simple technology, clear instructions and rigorous quality assessment, demonstrates the potential of citizen science actively involving land managers in agricultural research.

The quality of data collected by non-professional volunteers in citizen science programs is crucial to render them valid for implementing environmental resources management and protection plans. This study assessed the reliability of data collected by non-professional volunteers during the citizen science project Scuba Tourism for the Environment (STE), carried out in mass tourism facilities of the Red Sea between 2007 and 2015. STE involved 16,164 volunteer recreational divers in data collection on marine biodiversity using a recreational citizen science approach. Through a specifically designed questionnaire, volunteers indicated which of the seventy-two marine taxa surveyed were observed during their recreational dive, giving an estimate of their abundance. To evaluate the validity of the collected data, a reference researcher randomly dived with the volunteers and filled in the project questionnaire separately. Correlation analyses between the records collected by the reference researcher and those collected by volunteers were performed based on 513 validation trials, testing 3,138 volunteers. Data reliability was analyzed through 7 parameters. Consistency showed the lowest mean score (51.6%, 95% Confidence Interval CI 44.1–59.2%), indicating that volunteers could direct their attention to different taxa depending on personal interests; Percent Identified showed the highest mean score (66.7%, 95% CI 55.5–78.0), indicating that volunteers can correctly identify most surveyed taxa. Overall, results confirmed that the recreational citizen science approach can effectively support reliable data for biodiversity monitoring, when carefully tailored for the volunteer skills required by the specific project. The use of a recreational approach enhances massive volunteer participation in citizen science projects, thus increasing the amount of sufficiently reliable data collected in a reduced time.

Background/Context Memphis has, in many ways, become “ground zero” for neoliberal—or corporate—reform efforts, including a statewide turnaround school district, proliferation of charter schools, and value-added teacher evaluation measures. Along with these reforms come models of schooling that undermine the concept of the “community school,” leading to different conceptions of schools, teachers, and students. In this reform context, it is challenging to implement culturally relevant pedagogy (CRP) in a way that is true to its three pillars: academic achievement, cultural competence, and sociopolitical consciousness. The challenges that those who desire to implement CRP face can be categorized as either conceptual—representing a lack of understanding of CRP's conceptual underpinnings—or systemic—representing institutional barriers that impede the integration of CRP. Purpose/Objective The purpose of this analytic essay is to outline particular challenges to CRP in a hyper-reform context and to propose a framework describing changes that must take place in the process of implementing CRP. Setting The authors use Memphis as a model of hyper-reform and the backdrop for discussions of how CRP can be implemented in such a setting. Research Design This paper is an analytic essay. Conclusions/Recommendations We propose that effectively implementing CRP in a reform context is a process that requires a shift from a methodology of individualism to a methodology of collectivism. We align corporate reform with an individualist approach, while CRP, we argue, takes a more collectivist stance. The shift from individualism to collectivism also signals a shift in our conceptions of students, from trainees to successful citizens; teachers, from engineers to artists and activists; and schools, from corporations to community. A quick tour of the school reveals nothing out of the ordinary: classrooms, desks, cafeteria tables, bulletin boards, posters with announcements, etc. But a closer look exposes several clues to the influence of local and national trends in educational reform. First, it is a charter school, a fact attested to by the student uniforms ¾ plaid skirts and button-down shirts for girls, and khaki pants with shirt and tie for boys. Also, an observer would notice that each teacher's door is decorated with the name and paraphernalia of her or his college alma mater. The local public university is heavily represented on these doors, along with a small number of other local or regional universities. However, sprinkled throughout the school are decorations reflecting the universities of the Teach for America corps members who are part of the school's faculty: Syracuse, Valparaiso, Florida, Washington University, etc. In addition, a quick look inside each classroom reveals “data walls,” places to track student achievement over the course of the semester and school year. Similarly, an announcement on the television screen in the cafeteria announces the school's distinction as a “reward school,” meaning that the school's gains on the standardized achievement tests were among the highest in the state. In the same cafeteria is a bulletin board featuring examples of “nonverbal classroom cues,” “snapping,” and “tracking with your eyes.” The title of the bulletin board is, “What's the word on culture?”

Online learners are typically considered to be isolated learners, except for occasional opportunities to post views on an electronic bulletin board. This is not the team orientation that is so central to collaborative learning (CL) theory. Why does formal CL receive so little attention in online instruction? First, the teachers who do value CL generally are traditional educators and not involved in online instruction. Second, online teachers often have little understanding or appreciation for the formalisms of CL. In this chapter, electronic bulletin boards, although universally used, are shown to provide poor support for Collaborative Learning. As a better alternative, shared-document conferencing environments that allow learning teams to create academic deliverables are discussed. Finally, examples are given of well-known CL techniques, illustrating how these are implemented with shared-document conferencing.
