The aim of this study was to investigate if the effects of changes in physiological arousal on timing performance can be accurately predicted by the catastrophe model. Eighteen young adults (8 males, 10 females) volunteered to participate in the study following ethical approval. After familiarisation, coincidence anticipation was measured using the Bassin Anticipation Timer under four incremental exercise conditions: Increasing exercise intensity and low cognitive anxiety, increasing exercise intensity and high cognitive anxiety, decreasing exercise intensity and low cognitive anxiety and decreasing exercise intensity and high cognitive anxiety. Incremental exercise was performed on a treadmill at intensities of 30%, 50%, 70% and 90% heart rate reserve (HRR) respectively. Ratings of cognitive anxiety were taken at each intensity using the Mental Readiness Form 3 (MRF3) followed by performance of coincidence anticipation trials at speeds of 3 and 8 mph. Results indicated significant condition × intensity interactions for absolute error (AE; p = .0001) and MRF cognitive anxiety intensity scores (p = .05). Post hoc analysis indicated that there were no statistically significant differences in AE across exercise intensities in low–cognitive anxiety conditions. In high–cognitive anxiety conditions, timing performance AE was significantly poorer and cognitive anxiety higher at 90% HRR, compared to the other exercise intensities. There was no difference in timing responses at 90% HRR during competitive trials, irrespective of whether exercise intensity was increasing or decreasing. This study suggests that anticipation timing performance is negatively affected when physiological arousal and cognitive anxiety are high.  相似文献   

Computer‐based Learning in a Primary School: Differences between the early and later years of primary schooling     

Joanne Dwyer 《Asia-Pacific Journal of Teacher Education》2007,35(1):89-103

There have been increasing expectations that all primary school students and teachers actively use information and communications technologies (ICT) in their learning. In order to achieve this it is important that appropriate environments are set up to support the varying needs and potential of the different groups within the school context. However, in case studies of primary schools undertaken as part of the study Enhancing Learning Using New Technologies, also known as the E.ffects Project, our research indicated that the ICT learning environments established within schools often favoured the later primary year levels over the early primary school years. This paper will present illustrative evidence of this inequity using data extracted from the E.ffects Project case studies. It also discusses observed differences in approaches between early primary school years and later primary programs from the perspective of early childhood philosophies that underpin the first years of school.  相似文献   

Undergraduate Biotechnology Students’ Views of Science Communication     

Joanne Elisabeth Edmondston  Renato Schibeci 《International Journal of Science Education》2013,35(18):2451-2474

Despite rapid growth of the biotechnology industry worldwide, a number of public concerns about the application of biotechnology and its regulation remain. In response to these concerns, greater emphasis has been placed on promoting biotechnologists’ public engagement. As tertiary science degree programmes form the foundation of the biotechnology sector by providing a pipeline of university graduates entering into the profession, it has been proposed that formal science communication training be introduced at this early stage of career development. The aim of the present study was to examine the views of biotechnology students towards science communication and science communication training. Using an Australian biotechnology degree programme as a case study, 69 undergraduates from all three years of the programme were administered a questionnaire that asked them to rank the importance of 12 components of a biotechnology curriculum, including two science communication items. The results were compared to the responses of 274 students enrolled in other science programmes. Additional questions were provided to the second year biotechnology undergraduates and semi‐structured interviews were undertaken with 13 of these students to further examine their views of this area. The results of this study suggest that the biotechnology students surveyed do not value communication with non‐scientists nor science communication training. The implications of these findings for the reform of undergraduate biotechnology courses yet to integrate science communication training into their science curriculum are discussed.  相似文献

Artistic Ways of Knowing in Gifted Education: Encouraging Every Student to Think Like an Artist     

Joanne Haroutounian 《Roeper Review》2017,39(1):44-58

After decades of fluctuating presence in gifted education, the arts are surprisingly establishing themselves in academic classrooms, spurred by arts integration with science, technology, engineering, and mathematics (STEM) curricula or science, technology, engineering, art, and mathematics (STEAM). This renewed interest provides the opportunity to recognize the artistic process as an effective way to deepen and enlarge the scope of academic content. Teachers can readily identify potentially talented students in their classrooms who immerse themselves in arts activities. Students in every classroom, if provided with substantive arts integrated curricula, can learn to perceive with discrimination, metaperceptively mold creative interpretations, and communicate these performances/products expressively to others with insightful critiques. Artistic ways of knowing mirror the artistic process and provide the opportunity for every student in every classroom to think like an artist.  相似文献   

Girls debating penises,orgasms, masturbation and pornography     

Joanne Cassar 《Sex education》2017,17(1):1-13

This paper presents findings from a study of students’ writings about the erotic. These occurred in the form of graffiti and were scrawled on toilet doors for female students attending a higher education institution in Malta. The study explores how the erotic was defined and perceived by students, and how they attempted to create alternative spaces to explore their erotic selves through their writing. Foucault’s notion of heterotopia, which refers to spaces enacted for the Other, informs the analysis. Heterotopias subvert the order of spaces and mirror other dominant sites that make up the social fabric. This framework considers the lavatories as heterotopias, through which students broke silences and taboos about the erotic by challenging perspectives concerning sexual relatedness and erotic fantasy. In the absence of sexuality education in the curriculum of the institution in which the study took place, the study suggests that students may have sought out and constructed new ways of learning.  相似文献

ARE STUDENTS PREPARED TO COMMUNICATE? A CASE STUDY OF AN AUSTRALIAN DEGREE COURSE IN BIOTECHNOLOGY     

Joanne Edmondston  Vaille Dawson  Renato Schibeci 《International Journal of Science and Mathematics Education》2010,8(6):1091-1108

Public concerns about biotechnology have resulted in greater attention being paid to the mechanisms by which biotechnology is communicated with non-scientists, including the provision of science communication training. As undergraduate and postgraduate courses form the foundation of the biotechnology sector by providing a pipeline of university graduates entering into the profession, it has been proposed that formal science communication training be introduced at this early stage of career development. Using an Australian biotechnology degree course as a case study, this paper examines science communication training within this course and the views of past and present students towards this training. Interviews were undertaken with 22 stakeholders in the case, including undergraduate lecturers (who also supervise postgraduate research students), doctoral candidates and biotechnologists recently graduated from the course. Few of the students felt the course provided them with any form of science communication training, let alone training in how to engage non-scientists. Many were unaware of the training available to them and few of the lecturers were able to identify where communication skills are taught within the course. A previous study of this case has also shown that biotechnology undergraduates taking this course do not value communication with non-scientists. Clearly, the current state of science communication training for these students needs to be improved if they are to enter the biotechnology workforce as able civic scientists. The findings of this study may be useful for other university biotechnology courses which have yet to integrate science communication training into their curriculum.  相似文献   

Teaching Bioinformatics and Neuroinformatics by Using Free Web-based Tools     

William Grisham  Natalie A. Schottler  Joanne Valli-Marill  Lisa Beck  Jackson Beatty 《CBE life sciences education》2010,9(2):98-107

This completely computer-based module''s purpose is to introduce students to bioinformatics resources. We present an easy-to-adopt module that weaves together several important bioinformatic tools so students can grasp how these tools are used in answering research questions. Students integrate information gathered from websites dealing with anatomy (Mouse Brain Library), quantitative trait locus analysis (WebQTL from GeneNetwork), bioinformatics and gene expression analyses (University of California, Santa Cruz Genome Browser, National Center for Biotechnology Information''s Entrez Gene, and the Allen Brain Atlas), and information resources (PubMed). Instructors can use these various websites in concert to teach genetics from the phenotypic level to the molecular level, aspects of neuroanatomy and histology, statistics, quantitative trait locus analysis, and molecular biology (including in situ hybridization and microarray analysis), and to introduce bioinformatic resources. Students use these resources to discover 1) the region(s) of chromosome(s) influencing the phenotypic trait, 2) a list of candidate genes—narrowed by expression data, 3) the in situ pattern of a given gene in the region of interest, 4) the nucleotide sequence of the candidate gene, and 5) articles describing the gene. Teaching materials such as a detailed student/instructor''s manual, PowerPoints, sample exams, and links to free Web resources can be found at http://mdcune.psych.ucla.edu/modules/bioinformatics.  相似文献   

Joint attention strategies used by a preschool educator who is deaf     

Deluzio J  Girolametto L 《Journal of deaf studies and deaf education》2006,11(2):214-223

This exploratory study examined the attention-gaining and attention-regaining strategies used by a preschool educator who is Deaf during child-directed play. Four children (2 with typical hearing and 2 with severe-to-profound hearing loss) were videotaped interacting with the educator in two different play contexts. The educator used four different strategies to gain and to regain the children's attention: visual, visual using an American Sign Language (ASL) sign, tactile/vibratory, and observing/waiting. Overall, tactile and visual strategies were used with the same frequency and occurred more often than either waiting or using an ASL sign to establish joint attention. With the exception of waiting, all strategies were equally successful at gaining or regaining the children's attention. The knowledge and experience of educators with hearing loss potentially provide important insights into enhancing the effectiveness of the communicative environment for preschool children with hearing loss. The implications of this line of inquiry include training for educators on the effective use of strategies to establish joint attention with preschool children with hearing loss.  相似文献
