The authors tested whether students can be taught to better understand conventional representations in diagrams, photographs, and other visual representations in science textbooks. The authors developed a teacher-delivered, workbook-and-discussion–based classroom instructional method called Conventions of Diagrams (COD). The authors trained 1 experienced teacher to deliver COD to two 10th-grade biology classes (n = 31) and compared gains in diagram comprehension from COD to those from a business-as-usual control condition (n = 30) in 2 classrooms taught by the same teacher. Students in the COD condition showed statistically significantly greater growth in comprehension of literal and inferential biology diagrams. The control condition in some cases advantaged high-spatial, high-knowledge students, whereas the COD condition for the most part did not. Entries in the COD workbooks were analyzed for amount of student effort. Students with a combination of low pretest biology knowledge and low effort showed much lower gains from pretest to posttest on the inferential biology diagrams measure than did other students in the COD condition.  相似文献

Persistent biomechanical and jumping capacity alterations have been observed among female athletes who have sustained anterior cruciate ligament (ACL) injuries. The purpose of this study was to examine if biomechanical jumping differences persist among a cohort of elite female handball players with previous ACL reconstruction several years after return to top-level competition. In order to achieve this goal, a direct mechanics simplified analysis by using a single Inertial Sensor Unit (IU) was used. Twenty-one elite female (6 anterior cruciate ligament reconstructed and 15 uninjured control players) handball players were recruited and evaluated 6.0 ± 3.5 years after surgical anterior cruciate ligament reconstruction. Bilateral and unilateral vertical jumps were performed to evaluate the functional performance and a single inertial sensor unit was employed in order to collect 3D acceleration and 3D orientation data. Previously ACL-reconstructed analysed athletes demonstrated significant (p < 0.05) alterations in relation to the three-dimensional axis (XYZ) supported accelerations and differing jump phase durations, including jumping performance values, in both bilateral and unilateral jumping manoeuvres several years after ACL reconstruction. Identification of the encountered deficits through the use of an IU devise could provide clinicians with a new reliable tool for movement analysis in a clinical setting.  相似文献

Biting the Hand     
This column considers a wide range of issues concerning publishers, librarians, and academic authors from a personal perspective. It particularly focuses on the existence of marketing strategies when it comes to journal content, and considers what the role of all parties should be in the climate of publishing change.  相似文献

The opening column offers an overview of the roles and interrelationships among authors, publishers, intermediaries, libraries, and consortia in the production, selling, and procurement of serial publications and generally traces the evolution of the commerce over the last several decades.  相似文献

Aggregator products available to libraries are both praised and criticized by those that use them. The value of these products depends on perceived attributes and their relevance to the information needs of a library. Disconnects arise when aggregated products are either misunderstood or the structure and design of the products are not appropriately matched to end-user needs. More evaluation of these products is needed to ensure that they are serving end users as intended and are affordable into the future.  相似文献

The bankruptcy of two major serial agents within twelve years calls into question whether academic libraries are appropriately monitoring and overseeing the business partners to whom we entrust very large sums of money. The background events leading to the financial collapse of RoweCom/divine and Swets Information Services are reviewed and compared, along with a discussion of industry mechanisms to judge financial stability. Without adherence to financial best practices libraries risk being “left holding the bag” of problems, blame, and lost serial money.  相似文献

Because of the high cost of the 1990 census and the continuedundercoverage of some population subgroups, it has been suggestedthat administrative records be used to supplement or replaceconventional census-taking activities. Very little informationexists concerning public knowledge and attitudes on this topic.The most extensive information to date comes from questionsasked on several IRS surveys of taxpayers. In late 1993 an opportunitypresented itself to add a small number of questions about datasharing to national telephone surveys conducted by the WisconsinLetters and Sciences Survey Center. Here we report on an analysisof these data.  相似文献

As the traditional toys of the past are quickly being replaced with electronically “enhanced” toys, it is important to understand how these changes impact parent–child interactions, especially in light of the evidence that the richness and variety of these interactions have long‐term effects on diverse areas of cognition (Hart & Risley, 1995). Here, we compared the quantity and quality of the language children hear during play with either a traditional (nonelectronic) or an electronic shape sorter designed to teach children about geometric shapes. Spatial toys and spatial language, in particular, were explored since recent work has established that parents' use of spatial language links to children's short‐ and long‐term performance on spatial tasks (Pruden, Levine, & Huttenlocher, 2011), and that spatial skills are relevant to success in learning mathematics and science (Newcombe, 2010). Traditional toys prompted more parental spatial language and more varied overall language than did electronic toys.  相似文献
