Open Data: What It Is and Why You Should Care

Open data is information that is provided by public entities to be accessed and reused. Publishing open data is an excellent way to improve an organization’s transparency and provide insight into the value of the organization. Libraries are uniquely positioned to assist their patrons in the use of open data by making them aware of it and helping them access and use it. This article provides a short history of open data and explores ways that library trailblazers are already using open data as well as contributing open data for others to use. Getting started with open data involves identifying key open data resources such as data.gov, identifying library information that would be beneficial to publish, and creating programs that provide digital literacy training and create opportunities for patrons to engage with open data in new and creative ways.     

Teacher Contracts and Staff Development on Pupil‐Free‐Days

Sex bias in the curriculum is a relatively recent concern of the educational establishment. In 1975 the Sex Discrimination Act established the principle of equal access to educational facilities and equality of treatment for girls and boys. In the same year the HMI catalogued the sexually differentiated curriculum of girls and boys in Education Survey 21 and this surprisingly enlightened pamphlet thrust the issue onto the mainstream educational agenda. Up to that point sexual inequity in education had tended to be perceived as the prerogative of the teaching profession (overwhelmingly female but with few women in senior posts) and the particular promotion prospects of women teachers. The passing of the Sex Discrimination Act has done little to remedy the promotion prospects of women teachers, and in education generally the issue has moved beyond the realm of curricular access and into the less clearly charted territory of sexual differentiation: attention needs to be directed less to the examined curriculum patterns accessible to anyone willing to plough their way through the yearly statistics issued by the Department of Education and Science and focused more on the subtle processes through which girls' and boys' aspirations and expectations are shaped. Examination outcomes are convenient proof that ‘equal access’ has merely ensured that the educational experience of boys and girls continues to differ. This article, then, attempts to address some of the schooling processes as well as the curricular patterns.     

Characteristics and Levels of Sophistication: An Analysis of Chemistry Students’ Ability to Think with Mental Models

This study employed a case-study approach to reveal how an ability to think with mental models contributes to differences in students’ understanding of molecular geometry and polarity. We were interested in characterizing features and levels of sophistication regarding first-year university chemistry learners’ mental modeling behaviors while the learners were solving problems associated with spatial information. To serve this purpose, we conducted case studies on nine students who were sampled from high-scoring, moderate-scoring, and low-scoring students. Our findings point to five characteristics of mental modeling ability that distinguish students in the high-, moderate-, and low-ability groups from one another. Although the levels of mental modeling abilities have been described in categories (high, moderate, and low), they can be thought of as a continuum with the low-ability group reflecting students who have very limited ability to generate and use mental models whereas students in the high-ability group not only construct and use mental models as a thinking tool, but also analyze the problems to be solved, evaluate their mental models, and oversee entire mental modeling processes. Cross-case comparisons for students with different levels of mental modeling ability indicate that experiences of generating and manipulating a mental model based on imposed propositions are crucial for a learner’s efforts to incorporate content knowledge with visual-spatial thinking skills. This paper summarizes potential factors that undermine learners’ comprehension of molecular geometry and polarity and that influence mastery of this mental modeling ability.

Interpretations of graphs by university biology students and practicing scientists: Toward a social practice view of scientific representation practices

Using graphs is a key social practice of professional science. As part of a research program that investigates the development of graphing practices from elementary school to professional science activities, this study was designed to investigate similarities and differences in graph‐related interpretations between scientists and college students engaged in collective graph interpretation. Forty‐five students in a second‐year university ecology course and four scientists participated in the study. Guided by domain‐ specific concerns, scientists' graph‐related activities were characterized by a large number of experience‐based, domain‐specific interpretive resources and practices. Students' group based activities were characterized by the lack of linguistic distinctions (between scientific terms) which led to ambiguities in group negotiations; there was also a lack of knowledge about specific organism populations which helped field ecologists construct meaning. Many students learned to provide correct answers to specific graphing questions but did not come to make linguistic distinctions or increase their knowledge of specific populations. In the absence of concerns other than to do well in the course, students did not appear to develop any general interpretive skills for graphs, but learned instead to apply the professor's interpretation. This is problematic because, as we have demonstrated, there are widely differing viable interpretations of the graph. Suggestions for changes in learning environments for graphing that should alleviate this problem are made. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 1020–1043, 1999     

Different visual stimuli affect muscle activation at the knee during sidestepping

Increasing knee stability via appropriate muscle activation could reduce anterior cruciate ligament (ACL) injury risk during unplanned sidestepping. High-level athletes may activate their knee muscles differently from low-level athletes when responding to quasi-game realistic versus non game-realistic stimuli. Eleven high-level and 10 low-level soccer players responded to a non game-realistic arrow-planned condition (AP), a quasi game-realistic one-defender scenario (1DS) and two-defender scenario (2DS), and an arrow-unplanned condition (AUNP), that imposed increasing time constraints to sidestep. Activation from eight knee muscles during sidestepping was measured during pre-contact and weight-acceptance. Knee flexor-extensor co-activation ratios were established. Muscle activation levels increased by approximately 27% solely in the 1DS in both sidestepping phases. In the 2DS, the shift from a flexor dominant co-activation strategy in pre-contact toward extensor dominance in weight-acceptance commenced earlier for the high-level players. Quasi game-realistic information allowed for anticipatory increases in knee muscle activation regardless of expertise levels but only when the time demands to respond were low (1DS). High-level players were better at interpreting complex game-realistic information (2DS) to activate their knee extensors earlier in preparation for single-leg landing during weight-acceptance.
