Student difficulties in science learning are frequently attributed to misconceptions about scientific concepts. We argue that domain‐general perceptual processes may also influence students' ability to learn and demonstrate mastery of difficult science concepts. Using the concept of center of gravity (CoG), we show how student difficulty in applying CoG to an object such as a baseball bat can be accounted for, at least in part, by general principles of perception (i.e., not exclusively physics‐based) that make perceiving the CoG of some objects more difficult than others. In particular, it is perceptually difficult to locate the CoG of objects with asymmetric‐extended properties. The basic perceptual features of objects must be taken into account when assessing students' classroom performance and developing effective science, technology, engineering, and mathematics (STEM) teaching methods.  相似文献   

Red pigment production by Penicillium purpurogenum GH2 is influenced by pH and temperature     

Méndez A  Pérez C  Montañéz JC  Martínez G  Aguilar CN 《Journal of Zhejiang University. Science. B》2011,12(12):961-968

The combined effects of pH and temperature on red pigment production and fungal morphology were evaluated in a submerged culture of Penicillium purpurogenum GH2, using Czapek-Dox media with d-xylose as a carbon source. An experimental design with a factorial fix was used: three pH values (5, 7, and 9) and two temperature levels (24 and 34 °C) were evaluated. The highest production of red pigment (2.46 g/L) was reached with a pH value of 5 and a temperature of 24 °C. Biomass and red pigment production were not directly associated. This study demonstrates that P. purpurogenum GH2 produces a pigment of potential interest to the food industry. It also shows the feasibility of producing and obtaining natural water-soluble pigments for potential use in food industries. A strong combined effect (p<0.05) of pH and temperature was associated with maximal red pigment production (2.46 g/L).  相似文献

Organisational forms of science communication: the UK and Spanish European higher education systems as paradigms     

Ojeda-Romano  Gabriela  Fernández-Marcial  Viviana  Wilkinson  Clare  Stengler  A. Erik 《Higher Education》2022,84(4):801-825

As key elements in research and development systems, higher education institutions have been taking a leading role when it comes to communicating science and technology, but their performance has been inconsistent so far. In this critical and comparative study of the UK public engagement model and the Spanish scientific culture model, eighteen practitioners from higher education institutions across both regions were interviewed. A mixed qualitative data analysis has been performed identifying similarities and differences that unravelled the science communication management model in the two different higher education systems. This article provides evidence on how the institutionalisation of science communication is strongly influenced by key driving forces in the higher education context as well as the policies of administrations and other agents.

Mathe mit der Matte – Verkörperlichtes Training basisnumerischer Kompetenzen     

Tanja Link  Eva Johanna Schwarz  Stefan Huber  Dr. Ursula Fischer  Prof. Dr. Hans-Christoph Nuerk  Prof. Dr. Ulrike Cress  Prof. Dr. Korbinian Moeller 《Zeitschrift für Erziehungswissenschaft》2014,17(2):257-277

Basic numerical representations are seen as the building block for the successful development of more complex numerical and arithmetic competencies. Extending previous studies focusing on improving basic numerical representations by means of embodied training schemes, the current study focused on an embodied training of children’s place-value understanding. In this vein, 49 secondgraders were trained on solving a number line estimation task by stepping on different fields of a dance mat allowing for separate estimations of tens and units with more effort needed to step on the tens. In a partially randomized cross-over design, two control conditions were used to controll for training effects caused exclusively by the numerical content trained or the use of the dance mat. Interestingly, results revealed specific training effects after both the embodied and the control conditions. However, training effects were significantly more pronounced after the embodied training, thereby providing further evidence for the benefit of an embodied training of the place-value structure of the Arabic number system.  相似文献

TYPES OF ACADEMIC EXCHANGES AND TARGET GROUPS: BALANCES AND IMBALANCES     

Peter Fischer‐Appelt 《Higher Education in Europe》1990,15(1):46-51

The article considers, on one hand, the need to increase East‐West and West‐East academic exchanges in Europe, and on the other, to reduce or to rationalize imbalances. The three major segments of university populations, students, faculty members, and administrators, are each examined with regard to participation in exchanges, and pertinent suggestions are made. The author particularly insists on the importance of involving university administrators in exchange programmes even to the extent of moving them physically to other universities for stays of varying length. In closing, he evokes the setting up of the European Association of International Exchange Administrators.  相似文献   

Redefining Successful Interpretation in Art Museums     

Daryl Fischer  Lisa Levinson 《Curator: The Museum Journal》2010,53(3):299-323

Abstract This article aims to capture the spirit and content of a lively exchange among museum staff members at the Denver Art Museum. It began as a conference call and continued as an online dialogue about how definitions of success have evolved with advances in technology and changing expectations of visitors. Together we explored how DAM staff encourage more active participation in the museum and the creative tension that ensues between visitor co‐creation and institutional control. Woven throughout this conversation are examples that demonstrate the need to move fluidly between high tech and low tech interpretives, onsite and online experiences, and the impact of environments that break down museum stereotypes. It is our hope that this discussion will spark similar dialogues among colleagues in individual institutions and in the profession at large.
