Reading Practices in the Juvenile Correctional Facility Setting: Incarcerated Adolescents Speak Out     

Jade Wexler  Deborah K. Reed  Keith Sturges 《Exceptionality》2013,21(2):100-123

This multi-phasic, qualitative study explored the perceptions and provision of research-based reading instruction in the juvenile correctional facility setting. In three settings in two states, we interviewed students (n = 17), teachers (n = 5), and administrators (n = 3); and conducted two focus groups (n = 8), student surveys (n = 49), and seven observations of reading instruction. Our purposes were to (a) examine students' perceptions of themselves as readers, (b) their perceptions regarding the importance of reading, and (c) the reading practices implemented with juvenile offenders. Findings suggest that a majority of incarcerated students view reading as an important skill, but there is a large disparity in the amount and type of reading instruction they are provided.  相似文献   

The sharing‐out of nuclear attraction: or ‘I can't think about physics in chemistry’     

Keith S. Taber 《International Journal of Science Education》2013,35(8):1001-1014

Pre‐university chemistry students were found to consider that an atomic nucleus gives rise to a certain amount of attractive force which is shared equally among the electrons. Students used this ‘conservation of force’ principle in their explanations of such phenomena as patterns in ionization energy. It is suggested that teachers of chemistry should be aware that although they may be using conventional electrostatic principles in their presentations, their students may be reinterpreting their explanations through this alternative conception. The present research concerns the interface between two scientific disciplines (chemistry and physics) and suggests that learners do not readily integrate their knowledge across such domains. It is mooted that more research into how such demarcations encourage learners to compartmentalize their knowledge may prove fruitful.  相似文献   

Memories and scientific literacy: remembering exhibits from a science centre     

Maria I. Medved  Keith Oatley 《International Journal of Science Education》2013,35(10):1117-1132

The contribution of science centres to scientific literacy in the general adult population was explored through the study of memories of exhibits. Visitors participated in a structured interview about two exhibits they found interesting at the time of the initial visit and one month later. Participants retained stable episodic memories of the exhibits they chose, independently of whether or not they had discussed the exhibit in detail with the interviewer in the first interview. As to change in semantic memory, for some particpants the memories were enhanced between the initial and follow-up interview, for some they remained stable, and for others they deteriorated. There was an approximately equal proportion in each category. All participants reported affective involvement at both interview times, with happiness, followed by curiosity, being the most common. Post-visit integration of the exhibit information was common. The majority of participants reported talking to others about the exhibits. Moreover, one-third of the participants reported linking the exhibit memories to everyday occurrences, thus indicating an increased awareness of scientific phenomenon.  相似文献   

Exploring Conceptual Integration in Student Thinking: Evidence from a case study     

Keith S. Taber 《International Journal of Science Education》2013,35(14):1915-1943

Two reasons are suggested for studying the degree of conceptual integration in student thinking. The linking of new material to existing knowledge is an important aspect of meaningful learning. It is also argued that conceptual coherence is a characteristic of scientific knowledge and a criterion used in evaluating new theories. Appreciating this ‘scientific value’ should be one objective when students learn about the nature of science. These considerations imply that students should not only learn individual scientific models and principles, but should be taught to see how they are linked together. The present paper describes the use of an interview protocol designed to explore conceptual integration across two college‐level subjects (chemistry and physics). The novelty here is that a single interview is used to elicit explanations of a wide range of phenomena. The potential of this approach is demonstrated through an account of one student's scientific thinking, showing both how she applied fundamental ideas widely, and also where conceptual integration was lacking. The value and limitations of using this type of interview as one means for researching conceptual integration in students' thinking are discussed.  相似文献   

Students’ Conceptions of Ionisation Energy: A Cross‐cultural Study     

Kim Chwee Daniel Tan  Keith S. Taber  Xiufeng Liu  Richard K. Coll  Mercedes Lorenzo  Jia Li 《International Journal of Science Education》2013,35(2):263-283

Previous studies have indicated that A‐level students in the UK and Singapore have difficulty learning the topic of ionisation energy. A two‐tier multiple‐choice instrument developed in Singapore in an earlier study, the Ionisation Energy Diagnostic Instrument, was administered to A‐level students in the UK, advanced placement high school students in the USA, and first‐year university students in China, New Zealand, and Spain to determine whether the students from different countries and educational systems had similar conceptions and difficulties as the students in Singapore with the concepts assessed in the instrument. The results showed that, in general, the students in all six samples had similar alternative conceptions, which were grouped under the categories of octet rule framework, stable fully‐filled and half‐filled subshell conceptions, and conservation of force thinking. The students also resorted to relation‐based thinking when answering items involving the trend of ionisation energies across Period 3. Implications for teaching and further research are discussed.  相似文献   

Strategies for improving communication between teachers and school students about learning: a university/school collaborative research project     

Linda Haggarty  Keith Postlethwaite 《Educational Action Research》2013,21(3):449-478

The research reported here is the result of a collaborative project between a group of teachers in a secondary school and two university lecturers. The group has been meeting for several years and the issue of trying to improve communication arose as a result of findings from a previous study in the school. After reviewing the literature, we were able to identify actions for teachers to trial in the school and, following data collection and analysis, we were able to refine those actions for widespread adoption in the school. We were also able to identify issues that required further exploration. The research exemplifies a way in which university and school staff can engage in collaborative, high quality research. It also identifies some of the complexities involved for schools and teachers as they try to improve practice.  相似文献

Ecological Validity in Understanding Sport Performance: Some Problems of Definition     

Keith Davids 《Quest (Human Kinetics)》2013,65(2):126-136

One of the most significant aspects of current sport psychology research is the trend toward developing the relationship between theoretical concepts and practical applications. There have been many recent calls for the development of specific experimental paradigms closely linked to critical features of movement control and social interaction within specific frames of reference such as competitive sport (e.g., Lee & Young, 1985; Martens, 1979). The concept of ecological validity has been proposed as a crucial element of this current research thrust, and this paper attempts to identify and define some of the more important criteria underpinning ecologically valid research in sport psychology. Vision and sport performance is used as an exemplary area of investigation in which problematic and specific issues are examined. The basis of this critique has important implications for other areas of interest in the application of the behavioral sciences to sport. It is concluded that much greater debate must be stimulated concerning this important methodological principle, and a preliminary definition is provided for this purpose as well as to aid in the process of research evaluation in sport psychology.  相似文献   

Life under flow: A novel microfluidic device for the assessment of anti-biofilm technologies     

Maria Salta  Lorenzo Capretto  Dario Carugo  Julian A. Wharton  Keith R. Stokes 《Biomicrofluidics》2013,7(6)

In the current study, we have developed and fabricated a novel lab-on-a-chip device for the investigation of biofilm responses, such as attachment kinetics and initial biofilm formation, to different hydrodynamic conditions. The microfluidic flow channels are designed using computational fluid dynamic simulations so as to have a pre-defined, homogeneous wall shear stress in the channels, ranging from 0.03 to 4.30 Pa, which are relevant to in-service conditions on a ship hull, as well as other man-made marine platforms. Temporal variations of biofilm formation in the microfluidic device were assessed using time-lapse microscopy, nucleic acid staining, and confocal laser scanning microscopy (CLSM). Differences in attachment kinetics were observed with increasing shear stress, i.e., with increasing shear stress there appeared to be a delay in bacterial attachment, i.e., at 55, 120, 150, and 155 min for 0.03, 0.60, 2.15, and 4.30 Pa, respectively. CLSM confirmed marked variations in colony architecture, i.e.,: (i) lower shear stresses resulted in biofilms with distinctive morphologies mainly characterised by mushroom-like structures, interstitial channels, and internal voids, and (ii) for the higher shear stresses compact clusters with large interspaces between them were formed. The key advantage of the developed microfluidic device is the combination of three architectural features in one device, i.e., an open-system design, channel replication, and multiple fully developed shear stresses.  相似文献
