Classroom Learning Environments and Students' Approaches to Learning

Four hundred and eighty-four students from two metropolitan secondary schools completed the Learning Process Questionnaire, the Individualised Classroom Environment Questionnaire and the Learner Self Concept scale. Relationships between perceptions of the classroom learning environment, approaches to learning and self concept as a learner were investigated. Gender and level of schooling (junior high versus senior high) differences were examined. Results showed Deep Approaches to learning were significantly related to classroom learning environments which were perceived to be highly personalised and to be encouraging active participation in the learning process and the use of investigative skills in learning activities. High learner self concept was positively associated with Deep Approaches to learning and with classrooms perceived as high in Personalisation. It was negatively associated with Surface Approaches to learning. Differences in perceptions of learning environments and approaches to learning in relation to gender and level of schooling were small. The implications of these findings are discussed and strategies for facilitating Deep Approaches to learning are referred to. This revised version was published online in July 2006 with corrections to the Cover Date.     

Revenue and attendance simultaneous optimization in performing arts organizations

Performing arts organizations are characterized by different objectives other than revenue. Even if, on the one hand, theaters aim to increase revenue from box office as a consequence of the systematic reduction in public funds; on the other hand, they pursue the objective to increase its attendance. A common practice by theaters is to provide incentives to customers to discriminate among themselves according to their reservation price, offering a schedule of different prices corresponding to different seats in the venue. In this context, price and allocation of the theater seating area is decision variables that allow theater managers to manage their two conflicting goals to be pursued. In this paper, we introduce a multi-objective optimization model that jointly considers pricing and seat allocation. The framework proposed integrates a choice model estimated by multinomial logit model and the demand forecast, taking into account the impact of heterogeneity among customer categories in both choice and demand. The proposed model is validated with booking data referring to the Royal Danish theater during the period 2010–2015.     

Elbow joint kinematics during cricket bowling using magneto-inertial sensors: A feasibility study

Magnetic and inertial measurement units (MIMUs) may provide an accessible, three-dimensional, in-field alternative to laboratory-restricted marker-based motion capture. Existing upper limb MIMU models have predominantly been validated with low-velocity motion and their suitability for use with sport-based movements remains relatively untested. We propose a MIMU system approach to enable the estimation of anatomically meaningful and participant-specific elbow kinematics with considerations for use with cricket bowling. A novel standardised elbow reference posture of 90 degrees flexion and 0 deg pronation, and functional definition of elbow joint axes of rotation calibrated the MIMU method model before it was validated across three experiments: (1) simple elbow rotations with a mechanical linkage; (2) low-velocity elbow rotations in human participants; and (3) low-medium velocity sport-based movements in human participants. The proposed MIMU method demonstrated high elbow kinematic measurement agreement when compared with a criterion measure across all three conditions. However, during experiment 3, sensor components neared their measurement capacity and the MIMU method elbow flexion measurement variability increased. We conclude that the proposed MIMU method can estimate anatomically referenced, participant-specific joint angles, however, the hardware specifications of currently available systems may limit application in high-velocity/acceleration situations, preventing the measurement of cricket bowling in-field for now.     

Physiological characteristics of America's Cup sailors

The aim of this study was to assess the physiological profile of America's Cup grinders and mastmen, by measuring energy expenditure during sailing and assessing their aerobic and anaerobic fitness. The study focused on estimating the energy used during grinding activity, by measuring oxygen uptake (VO(2)) during sail setting in real sailing conditions. In the laboratory, using an arm-cranking ergometer, we measured VO(2peak) during an incremental maximal exercise test and total energy expended during the effort and recovery phases of an all-out test that simulated grinding activity, in six grinders and mastmen and ten sailors of the same crew. Total energy used during grinding corresponded to 45% (s = 9) and 51% (s = 5) of that used in the all-out test (234 kJ, s = 21.7) for tacks and gybes, respectively. In both grinding activity and the all-out test, VO(2) increased during and after the effort. The "VO(2) top value" was 53% (s = 8.6), 68% (s = 5.5), and 78% (s = 3.1) of VO(2peak) (4.7 l . min(-1), s = 0.43) in tacks, gybes, and the all-out test, respectively. During fast sequences of grinding activity, the "VO(2) top value" reached 65% (s = 7.1) VO(2peak) in tacks and 91% (s = 3.3) VO(2peak) in gybes. Our results suggest that grinders and mastmen are characterized by a high anaerobic capacity but their performance can be improved by powering aerobic fitness, to increase this energy contribution to all-out efforts and to guarantee fast recovery when grinding activity is repeated with short rest intervals.     

Eozoön: debunking the dawn animal

Discovered in the nineteenth century by the Canadian Geological Survey, the Eozo?n canadense fossil, or 'dawn animal of Canada', created a sensation in the geological community. Only a few initially challenged its status as a fossil organism, including two professors in the remote Irish town of Galway. These men claimed that Eozo?n was nothing more than a mineral formation and did not represent the discovery of the primordial organism. Supporters of Eozo?n closed ranks and a heated debate soon broke out in a range of periodicals. The story of Eozo?n lays bare the construction of scientific credibility, a process that was threatened in the second half of the nineteenth century by the proliferation of popular science.     

Assessing Research Compliance for Federally Funded Projects: The Good,the Bad,and the Publicly Accessible

Abstract

In 2016, Utah State University launched a program to ensure their campus’ federal grant recipients were in compliance with funder mandates to share any data or publications produced as a result of the award. This article discusses how a cross-institutional team of librarians and administrators evaluated the success of this program using online asynchronous focus groups (OAFG) in conjunction with a traditional survey. The challenges and successes of using OAFGs to assess library services are also examined. An OAFG gave participants greater convenience, flexibility, participation, and time to craft answers, eliminating some of the hurdles to traditional focus group participation.     

Researchers Apply Lesson Study: A Cycle of Lesson Planning,Implementation, and Revision

Scripted lesson plans and/or professional development alone may not be sufficient to encourage teachers to reflect on the quality of their teaching and improve their teaching. One learning tool that teachers may use to improve their teaching is Lesson Study (LS). LS is a collaborative process involving educators, based on concepts of iteration and revision, to improve instruction. The initial use of an adapted version of LS referred to as a microteaching lesson study (MLS) is described in this article. Our purpose is to illustrate the process of MLS used by a group of researchers when developing lesson plans for teaching students with learning disabilities. We describe MLS, and then (1) share an application of MLS used by a research team in developing a writing intervention, and (2) discuss how the MLS format was mirrored with K‐12 teachers during professional development training.
