Curriculum as Experienced by Students: How Teacher Identity Shapes Science Notebook Use     

Lauren Madden  Eric N. Wiebe 《Research in Science Education》2013,43(6):2567-2592

This mixed-methods case study examined the notebook entries of one class of 22 second graders as a way of examining how teacher identity shaped the way students experienced their science curriculum. These notebook entries were created during lessons with three different teachers over the course of one school year, using similar kit-based materials to teach science. The entries were coded for inquiry phase, percent missing or incomplete entries, and driving force (teacher-driven, student-driven, or balanced); chi-squared analyses revealed significant differences among the notebook entries created by the same students during lessons taught by each of the three teachers. Qualitative observations of each teachers' instruction around notebook use supported these quantitative differences, and suggested that the differences in curriculum as experienced by students could be attributed to differences in teacher identity, both who the teacher is and what they do in the classroom. These findings indicate that students' notebooks are useful tools for examining how teachers' identities might shape how elementary students experience science curriculum, and that they can be used to help structure more effective professional development plans for each teacher.  相似文献

Training Alone Is Not Enough     

Lauren Crigler  Alfredo L. Fort  Orla de Diez  Susan Gearon  Hayk Gyuzalyan 《Performance Improvement Quarterly》2006,19(1):99-116

Improving healthcare services in the developing world remains a major goal for many organizations and despite enormous training and program investments from international organizations, service improvements have been modest. This study looks at how to improve results by examining the relationship between the conditions in a healthcare providers' work environment and his or her performance. Drawing upon a human performance model that assumes that performance expectations, timely feedback, adequate environment, incentives, and skills and knowledge are required for a worker to perform well, this study explores how these conditions might affect healthcare provider performance in four countries. The study successfully shows that although multiple conditions were deficient or missing in every country, significant association is found between the performance of workers and conditions in the workers environment. Further, when viewed across all countries, non‐monetary incentives is the most powerful “predictor‘ of performance when compared with other factors. Of particular interest to Performance Improvement practitioners, knowledge and skills surfaced as important in only three of eight possible cases (with multiple cases in each country)—the least influential factor overall.  相似文献   

Promoting multicultural understanding and positive self-concept through a distance learning community: Cultural connections     

Lauren Cifuentes  Karen L. Murphy 《Educational technology research and development : ETR & D》2000,48(1):69-83

We explored the effectiveness of distance learning and multimedia technologies in facilitating an expanded learning community among two teachers and their students in geographically separated schools. The teachers collaboratively developed curricular activities and identity-forming multicultural activities for their K-12 students to conduct over the distance. Predominantly Hispanic students in a school on the Texas border with Mexico communicated regularly over a school year with diverse students in a partner school hundreds of miles to the north. They participated in collaborative activities and shared multimedia files via interactive videoconference. Using qualitative research methods, we discovered that the participating teachers developed empowering multicultural relationships while their students developed multicultural understanding and positive self-concept. Examples of empowerment and positive self-concept included raised levels of academic aspirations and heightened poise during public speaking. Thanks to Lucy Cifuentes, Sharon Clark, Trina Davis, and Teri Metcalf for their contributions of raw data and earlier versions of writings about Cultural Connections. Also, thanks to Ester Gonzales and Trina Davis for permitting us to use their names in this paper.  相似文献   

Can sit-to-stand muscle power explain the ability to perform functional tasks in adults with severe obesity?     

Samuel T. Orange  Phil Marshall  Leigh A. Madden  Rebecca V. Vince 《Journal of sports sciences》2019,37(11):1227-1234

This study examined the relationship between sit-to-stand (STS) power and physical function in adults with severe obesity. Thirty-eight adults (age: 44 ± 12 years; body mass index [BMI]: 45.2 ± 7.8 kg/m²) completed evaluations of STS power, strength and functional performance. STS power was measured with a wearable inertial sensor, strength was assessed with the isometric mid-thigh pull, and function was measured with the timed up-and-go (TUG), six-minute walk test (6MWT) and 30-s chair STS. Power and strength (normalised to body mass) entered regression models in addition to age, gender, BMI and physical activity (daily step count). Power displayed large univariate associations with TUG (r = 0.50) and 30-s chair STS (r = 0.67), and a moderate association with 6MWT (r = 0.49). Forward stepwise regression revealed that power independently contributed to TUG (β = ?0.40, p = 0.010), 30-s chair STS (β = 0.67, p < 0.001) and 6MWT performance (β = 0.27, p = 0.007). Power also appeared to be a superior determinant of function compared with strength. Power generated via the STS transfer largely underpins the ability to perform functional tasks in adults with severe obesity, although intervention studies are required to investigate a potentially causal relationship.  相似文献   

The influence of race length on arterial compliance following an ultra-endurance marathon     

Alis Bonsignore  Shannon S. D. Bredin  Holly Wollmann  Barb Morrison  Andrew Jeklin  Lauren Buschmann 《European Journal of Sport Science》2017,17(4):441-446

There is inconclusive evidence concerning the effects of routine participation in ultra-endurance events on cardiovascular disease (CVD) risk. Arterial compliance is a reliable, non-invasive, and effective tool for evaluating CVD risk. The purpose of this research was to examine if race length influences acute changes in arterial compliance following an ultra-marathon event. A total of 46 ultra-marathon runners were recruited including 21 participants (39.8?±?8.3?years, 6 females) in the 80-km event and 25 participants (43.7?±?9.8?years, 3 female) in the 195-km event. Arterial compliance was measured via radial applanation tonometry (CR-2000, HDI) for diastolic pulse contour analysis before and following the race. Significant between-group differences were found for changes in large arterial compliance with a decrease (increase in stiffness) following the 195-km event and an increase following the 80-kilometre event (p?<?.05). Longer race lengths are associated with greater reductions in large arterial compliance following recreational ultra-marathon running. Assessment of arterial compliance might be a useful prognostic tool to assess the long-term risk of CVD among ultra-marathon runners.  相似文献

Key points

• Testing for accessibility after extensive changes to a website and addressing them as technical debt is unsustainable in the long term.
• To stay modern and efficient, providers of digital content to academic institutions should build accessibility into development.
• For JSTOR, working with participating institutions to understand their concerns was essential to reaching WCAG 2.0 AA conformance.
• With Artstor recently joining ITHAKA, we face the challenge of making a visual archive accessible.
