Where to go: Computational and visual what-if analyses in soccer

ABSTRACT

To prepare their teams for upcoming matches, analysts in professional soccer watch and manually annotate up to three matches a day. When annotating matches, domain experts try to identify and improve suboptimal movements based on intuition and professional experience. The high amount of matches needing to be analysed manually result in a tedious and time-consuming process, and results may be subjective. We propose an automatic approach for the realisation of effective region-based what-if analyses in soccer. Our system covers the automatic detection of region-based faulty movement behaviour, as well as the automatic suggestion of possible improved alternative movements. As we show, our approach effectively supports analysts and coaches investigating matches by speeding up previously time-consuming work. We enable domain experts to include their domain knowledge in the analysis process by allowing to interactively adjust suggested improved movement, as well as its implications on region control. We demonstrate the usefulness of our proposed approach via an expert study with three invited domain experts, one being head coach from the first Austrian soccer league. As our results show that experts most often agree with the suggested player movement (83%), our proposed approach enhances the analytical capabilities in soccer and supports a more efficient analysis.     

Calcium isotope compositions as a means to trace carbonate recyclingOA

<正>Marine carbonates, such as sedimentary carbonates and secondary carbonates formed during marine alteration processes, are returned to the mantle at subduction zones, and their fates regulate the global carbon cycle. Some carbonates are destroyed at the subduction zones,     

Characterizing Students’ Attempts to Explain Observations from Practical Work: Intermediate Phases of Understanding

This study aims to characterize a group of students’ preliminary oral explanations of a scientific phenomenon produced as part of their learning process. The students were encouraged to use their own wordings to test out their own interpretation of observations when conducting practical activities. They presented their explanations orally in the whole class after having discussed and written down an explanation in a small group. The data consists of transcribed video recordings of the presented explanations, observation notes, and interviews. A genre perspective was used to characterize the students’ explanations together with analysis of the students use of scientific terms, gestures, and the language markers “sort of” and “like.” Based on the analysis we argue to separate between event-focused explanations, where the students describe how objects move, and object-focused explanations, where the students describe object properties and interactions. The first type uses observable events and few scientific terms, while the latter contains object properties and tentative use of scientific terms. Both types are accompanied by an extensive use of language markers and gestures. A third category, term-focused explanations, is used when the students only provide superficial explanations by expressing scientific terms. Here, the students’ use of language markers and gestures are low. The analyses shows how students’ explanations can be understood as tentative attempts to build on their current understanding and observations while trying to reach out for a deeper and scientific way of identifying observations and building explanations and new ways of talking.     

A novel approach to London: Infusing ethnography and the study abroad experience

Courses: Qualitative Research Methods, Ethnographic Research Methods.

Objective: This purpose of this activity is to document the enculturation process through which students begin to understand a new culture during a study abroad experience. To accomplish this, we created a new pedagogical approach for study abroad experiences that involved a combination of academic and fictional readings to help students make sense of and perform ethnographic research techniques.     

Tracking Professional Development of Novice Teachers when Integrating Technology in Teaching Mathematics

This research traced changes in choices of technological tools and attitudes toward technology use among novice mathematics teachers at three stages of their professional development: as pre-service teachers, a year later, and in their work as novice teachers. At each stage, the participants were required to evaluate the benefits of technology use in their learning/teaching.

We found that the novice mathematics teachers used a variety of technological tools, while as students they preferred to use digital presentations or dynamic software. Moreover, the novice teachers used two additional tools: the school platform and the WhatsApp instant messaging application. The novice teachers placed significantly higher value on the benefits of using technology in teaching in terms of improvement in learning, enhancement of pupils' motivation and increased effectiveness of the lesson. These results indicated that only as practical teachers were the participants able to see the benefits of technology.     

Inarticulate Transfer: Do Community College Students Understand Articulation Agreements?

Only 25% of community college students transfer to a 4-year institution within 5 years, and only 17% earn a bachelor’s degree within 6 years of transferring (Jenkins &; Fink, 2015). In response, community colleges have partnered with 4-year institutions to draft articulation agreements, outlining transfer policies and procedures for specific academic programs (Montague, 2012). However, no extant research has examined whether these articulation agreements are readable by community college students. This study examines 100 articulation agreements between 2- and 4-year institutions to answer the question: do community college students understand articulation agreements? Findings indicate that 93% of articulation agreements are unreadable by community college students of average reading ability, with 69% of articulation agreements written at or above a 16th-grade reading level. Implications for practitioners and future research are addressed.
