Children’s Teleological Intuitions: What Kind of Explanations Do 7–8 Year Olds Give for the Features of Organisms, Artifacts and Natural Objects?

Research has shown that children usually provide teleological explanations for the features of organisms from a very early age (3?C4?years old). However, it is not clear if teleology is applied selectively for organisms, or if it is generally applied to other objects as well (artifacts and non-living natural objects). The present study examined whether 7?C8?year old students provided teleological explanations for particular organisms, artifacts and natural objects. We investigated whether children's familiarity with these objects influenced the types of explanations they gave. Finally, we also investigated correlations between 'teleology' and 'usefulness' in children's explanations. The results indicate that 7?C8?year olds are able to distinguish between living and non-living entities, as well as that they provide teleological explanations mostly for organisms and artifacts. This may have important implications for biological education, since teleological explanations in classrooms are likely to pose important conceptual obstacles to the development of a scientific understanding of evolution.     

Developing and evaluating instructionally sensitive assessments in science

The purpose of this article is to address a major gap in the instructional sensitivity literature on how to develop instructionally sensitive assessments. We propose an approach to developing and evaluating instructionally sensitive assessments in science and test this approach with one elementary life‐science module. The assessment we developed was administered to 125 students in seven classrooms. The development approach considered three dimensions of instructional sensitivity; that is, assessment items should: represent the curriculum content, reflect the quality of instruction, and have formative value for teaching. Focusing solely on the first dimension, representation of the curriculum content, this study was guided by the following research questions: (1) What science module characteristics can be systematically manipulated to develop items that prove to be instructionally sensitive? and (2) Are the instructionally sensitive assessments developed sufficiently valid to make inferences about the impact of instruction on students' performance? In this article, we describe our item development approach and provide empirical evidence to support validity arguments about the developed instructionally sensitive items. Results indicated that: (1) manipulations of the items at different proximities to vary their sensitivity were aligned with the rules for item development and also corresponded with pre‐to‐post gains; and (2) the items developed at different distances from the science module showed a pattern of pre‐to‐post gain consistent with their instructional sensitivity, that is, the closer the items were to the science module, the larger the observed gains and effect sizes. © 2012 Wiley Periodicals, Inc.

Students’ and teachers’ perspectives about quality of engineering education in Portugal

Quality in higher education is a subject of increasing importance. This idea can be supported by looking at different sources, namely, the scientific literature, national and transnational governments’ policies, such as those emerging from the Bologna Process. Also, the internationalisation of higher education and, within it, students’ and staff mobility among institutions, has brought to the agenda the quality issue, particularly with regard to the teaching and learning process. Several authors argue that the meaning of quality depends on who defines it. This article focuses on a study that looks at how teachers and students in higher education institutions, in Portugal and in the domain of Engineering, see the quality issue. Data was collected through interviews to teachers (six) and students (38) in two different Portuguese institutions. The results indicate that, although teachers and students refer to the same dimensions that influence quality, they have different perspectives about their importance. From the point of view of the authors, this discrepancy requires some pedagogical actions in the context where the study was developed and, also, further research to see if the same tendency exists in different settings.     

Fitting Multidimensional Amotivation into the Self-Determination Theory Nomological Network: Application in School Physical Education

The present study investigated the nomological validity of the Amotivation Inventory–Physical Education (Shen, Wingert, Li, Sun, & Rukavina, 2010b Shen, B., Wingert, R. K., Li, W., Sun, H. and Rukavina, P. B. 2010b. An amotivation model in physical education. Journal of Teaching in Physical Education, 29: 72–84. [Web of Science ®] , [Google Scholar]) scores by examining the associations of ability, effort, value, and task characteristics amotivation beliefs with self-determination theory variables. Data were collected from 401 fifth- and sixth-grade students, 416 middle-school students, and 401 high-school students. After providing support for the correlated four-factor structure, the hierarchical structure, internal consistency, and composite reliability of the Amotivation Inventory–Physical Education scores, large negative correlations emerged with perceived autonomy support by the PE teacher; needs for autonomy, competence, and relatedness; identified regulation; intrinsic motivation; and students' subjective vitality. Strong positive correlations were obtained with unidimensional amotivation and external regulation, and weak correlations were obtained with introjected regulation. Also, multidimensional amotivation beliefs partially mediated the relationship between the need for autonomy and subjective vitality. The results provided support for the nomological aspect of construct validity of the Amotivation Inventory–Physical Education scores.     

Biomechanical analysis of the penalty-corner drag-flick of elite male and female hockey players

The aim of this study was to analyse the kinematic sequencing in the penalty-corner drag-flicks of elite male and female field hockey players of international calibre. Thirteen participants (one skilled male drag-flicker and six male and six female elite players) participated in the study. An optoelectronic motion analysis system was used to capture the drag-flicks with six cameras, sampling at 250 Hz. Select ground reaction force parameters were obtained from a force platform which registered the last support of the front foot. Twenty trials were captured from each subject. Both player groups showed significantly (p < 0.05) smaller ball velocity at release, peak angular velocity of the pelvis, and negative and positive peak angular velocities of the stick than the skilled subject. Normalised ground reaction forces of the gender groups were also smaller than that of the skilled drag-flicker. By comparing these players we established that the cues of the skill level are a wide stance, a whipping action (rapid back lift) of the stick followed by an explosive sequential movement of the pelvis, upper trunk and stick.     

Desaturation Patterns Detected by Oximetry in a Large Population of Athletes

Optimal exercise performance in well trained athletes can be affected by arterial oxygen saturation failure. Noninvasive detection of this phenomenon when performing a routine ergometric test can be a valuable tool for subsequent planning of the athlete's training, recovery, and nutrition. Oximetry has been used to this end. The authors studied 339 athletes performing a similar exercise trial under well controlled environmental conditions. Maximum speed, oxygen uptake, and heart rate levels were simultaneously measured. From the obtained data, six patterns were found: (a) athletes in whom oxygen saturation is constant (≥ 95%) during test execution; (b) athletes displaying a progressive desaturation with incremental exercise intensities; (c) athletes presenting a transient desaturation in the anaerobic threshold region; (d) athletes starting with a mild-to-moderate desaturation at the beginning of the test, but reaching normal saturation values at the end; (e) athletes displaying mild-to-moderate desaturation levels throughout the whole test; and (f) athletes displaying a transient desaturation in the anaerobic threshold region and a new desaturation at the end of the test. In conclusion, it is believed that establishment of desaturation patterns by validated oximetry could be a first approach to evaluate the adaptation of the cardiorespiratory system to exercise intensity, helping to improve results.     

Evolving Workflows: Knowing when to Hold'em,Knowing when to Fold'em

Electronic resource management (ERM) workflows in academic libraries are characterized by their complex and constantly shifting nature. This article describes four phases of effective workflow management including careful planning, development of workflow strategies, staffing and identification of resources, and integration of ERM and communication tools. The importance of supporting effective communication strategies is emphasized throughout the article. Information obtained from informal interviews with eight academic librarians provides discussion points on workflows given up and workflows maintained as libraries transition to larger electronic resource collections.     

Chile: From the Pay-for-Access Model to a Civic Right to Information

The earlier funding model adopted by Chile to implement programs of access to scientific information had been unique within Latin America. Countries like Argentina, Brazil, and Mexico had successfully tested charging the service provision to the nation’s general budget, and had achieved a model of universal access. Chile, on the other hand, had followed a path where a co-financing model and the derived logic regarding action of the state created the Electronic Library of Scientific Information Program (BEIC), which limited benefits to only those users who belonged to the institutions that had the ability to pay and already had a consolidated community of researchers. This article reviews public policy options adopted to ensure access to resources of scientific information by the communities of researchers and reflects on the important change that occurred in 2012, when the Chilean State decided to finance the entire cost of the BEIC Program and to define access to information as a de facto universal right. The article also discusses future challenges and new programmatic features as a result of periodic assessments of the program.     

Interpersonal Communication Motives as a Predictor of Early and Middle Adulthood Siblings' Use of Relational Maintenance Behaviors

The purpose of this study was to examine whether early and middle adulthood siblings' use of relational maintenance behaviors (i.e., positivity, openness, assurances, networks, tasks) is predicted, after controlling for relational closeness, by their interpersonal communication motives (i.e., affection, inclusion, control, pleasure, relaxation, escape). Participants were 122 individuals who reported on their relationship with a sibling. Results indicated that for the positivity relational maintenance behavior, psychological closeness, the affection motive, and the control motive were significant contributors; for the openness, assurances, and tasks relational maintenance behaviors, psychological closeness and the affection motive were significant contributors; and for the networks relational maintenance behavior, psychological closeness was a significant contributor.
