Improved learning efficiency and increased student collaboration through use of virtual microscopy in the teaching of human pathology

The implementation of virtual microscopy in the teaching of pathology at the Bloomington, Indiana extension of the Indiana University School of Medicine permitted the assessment of student attitudes, use and academic performance with respect to this new technology. A gradual and integrated approach allowed the parallel assessment with respect to both the virtual and optical microscopes. Student survey data indicated that the virtual imaging technology was enthusiastically received, and aggregate grade comparisons with the previous classes showed no decrease in content mastery. Survey questions assessing a variety of parameters reveal improved time and resource utilization, as well as increased student collaboration. Even so, 50% of the respondents indicated having both optical and virtual microscopes available was preferable. Anat Sci Ed 1:240–246, 2008. © 2008 American Association of Anatomists.     

An analysis of the effects of geographic-demographic factors on college attendance

Geographic and demographic characteristics of the 120 Kentucky counties were utilized to group counties with similar characteristics. Factor analysis and then cluster analysis were used to establish four county groupings. ACT test results and demographic data, and enrollment data for 1977, 1978, 1979, and 1980 for those 1977 high school graduates enrolled in Kentucky state-supported colleges and universities, fall semester 1977, were analyzed to determine whether geographic origin influenced college attendance. Four hypotheses tested enrollment, persistence, and transfer activities; college-going rates; and academic achievement of students. Test results revealed significant differences and the null hypotheses were rejected.     

Being a parent's eyes and ears: emotional literacy and empathy of children whose parents have a sensory disability

Children of parents with sensory disability may feel that their experience helped nurture their sense of empathy. The study was designed to examine the connection between parents’ sensory disability (visual disability to blindness and hearing disability to deafness) and the empathy and emotional literacy of their non‐sensory‐disabled children. Participants were 77 children aged 7–17 – 37 children of parents with a sensory disability and 40 children of parents with no such disability. Questionnaires to check empathy and emotional literacy were accompanied by a demographic questionnaire. Findings revealed that levels of empathy and emotional awareness of others (a measure of emotional literacy) were higher among children of parents with a sensory disability than among children of parents without a disability. The results expand the literature on that subject and shed light on the important issues of empathy and emotional literacy in families with disability.     

Local links,local knowledge: Choosing care settings and schools

This article draws on data from two recently completed Economic and Social Research Council funded projects in order to examine class differences and similarities in choice of school and choice of childcare. The authors argue that there is every reason to believe that in many circumstances, within its particular mechanisms and practices, choice produces specific and pervasive forms of inequity. The processes by which working‐class parents in one study chose care settings and schools could be seen as less skilled, less informed, less careful than the decision making of many of the middle‐class respondents. However, this is not an argument that the authors advance, noting instead that the practices and meanings of choice are subject to significant social, cultural and economic variations in terms of who gets to choose, who gets their choices, and what, how and why people choose when they are able to. The authors argue that there are alternative sets of priorities in play for the working‐class respondents, involving attachments to the communal and the local.     

Scoring Constructed Responses Using Expert Systems

The use of constructed-response items in large scale standardized testing has been hampered by the costs and difficulties associated with obtaining reliable scores. The advent of expert systems may signal the eventual removal of this impediment. This study investigated the accuracy with which expert systems could score a new, nonmultiple-choice item type. The item type presents a faulty solution to a computer programming problem and asks the student to correct the solution. This item type was administered to a sample of high school seniors enrolled in an Advanced Placement course in Computer Science who also took the Advanced Placement Computer Science (APCS) examination. Results indicated that the expert systems were able to produce scores for between 82% and 95% of the solutions encountered and to display high agreement with a human reader on the correctness of the solutions. Diagnoses of the specific errors produced by students were less accurate. Correlations with scores on the objective and free-response sections of the APCS examination were moderate. Implications for additional research and for testing practice are offered.     

Parallel assessment of nutrition and activity in athletes: validation against doubly labelled water, 24-h urea excretion, and indirect calorimetry

The assessment of nutrition and activity in athletes requires accurate and precise methods. The aim of this study was to validate a protocol for parallel assessment of diet and exercise against doubly labelled water, 24-h urea excretion, and respiratory gas exchange. The participants were 14 male triathletes under normal training conditions. Energy intake and doubly labelled water were weakly associated with each other (r = 0.69, standard error of estimate [SEE] = 304 kcal x day(-1)). Protein intake was strongly correlated with 24-h urea (r = 0.89) but showed considerable individual variation (SEE = 0.34 g kg(-1) x day(-1)). Total energy expenditure based on recorded activities was highly correlated with doubly labelled water (r = 0.95, SEE = 195 kcal x day(-1)) but was proportionally biased. During running and cycling, estimated exercise energy expenditure was highly correlated with gas exchange (running: r = 0.89, SEE = 1.6 kcal x min(-1); cycling: r = 0.95, SEE = 1.4 kcal x min(-1)). High exercise energy expenditure was slightly underestimated during running. For nutrition data, variations appear too large for precise measurements in individual athletes, which is a common problem of dietary assessment methods. Despite the high correlations of total energy expenditure and exercise energy expenditure with reference methods, a correction for systematic errors is necessary for the valid estimation of energetic requirements in individual athletes.     

The politics of teaching as an occupation in the professional borderlands: the interplay of gender,class and professional status in a biographical study of trainee teachers in England

A lack of esteem for teachers and the teaching profession is a central tenet underpinning policy reforms put forward by the 2010 UK Government White Paper ‘The Importance of Teaching’. This article argues that the policy problem and solutions presented in the White Paper lack awareness of the historical and social positioning of teaching. Drawing on in-depth interviews with 32 London-based secondary teacher training students from various social class and ethnic backgrounds, this paper asks how the profession is perceived and what sort of choice it is for the trainees. It employs a Bourdieusian lens and concepts of social and cultural capital to examine the interplay of gendered, classed and ‘raced’ biographies in relation to individuals’ decisions to become teachers. Understanding the social world as ‘accumulated history’, as Bourdieu does, stresses that experiences and outcomes are rooted and collected in a series of historical structures and functionings. The paper argues that the ambiguous status of the profession is both a function and an effect of its conceptualisation as feminised. It also asks whether the weak professional standing of teaching has further destabilising consequences in the present political moment where a string of neoliberal and neoconservative policy reforms reshape the profession.     

Policy enactments in the UK secondary school: examining policy,practice and school positioning

This paper presents a first attempt in an ongoing research study of the policy environments in four UK secondary schools to examine policy enactment, where ‘enactment’ refers to an understanding that policies are interpreted and ‘translated’ by diverse policy actors in the school environment, rather than simply implemented. The paper is divided into two parts. The first part presents an audit of the policies encountered in four case study schools in the south‐east of England. The second part looks at one current English government policy, namely personal learning and thinking skills, and how this is taken up in two of the case study schools. In this way, the paper not just explores why a policy is adopted but also illustrates the capacity for school‐based policy elaboration, where schools produce their own ‘take’ on policy, drawing on aspects of their culture or ethos, as well as on the situated necessities.     

The Technology Policy Unit of the University of Aston in Birmingham

The purpose of this research project was to study how students in the first years of elementary school (children from 7 to 10 years of age) are initiated into the construction of explanations of physical phenomena in the teaching of science. With this purpose in mind, we organized classes based on the proposition of investigative problems, where children, working in groups, could solve problems by raising and testing their own hypotheses. They would then attempt, by means of general discussion organized by the teacher, to discuss how each problem was solved and why it worked. We videotaped a series of classes in which the students solved 15 different investigative problems. We also analysed the teacher/student interactions that took place (in this paper, we present data on two of these classes). Based on our data we found that students construct their own causal explanations by following a sequence of stages that includes the appearance of novelties. We also discuss how our data relate to the teacher's role in the classroom and to the organization of science teaching at this level.     

Slovak high school students' attitudes toward computers

The pervasive involvement of information and communication technologies and computers in our daily lives influences changes of attitude toward computers. We focused on finding these ecological effects in the differences in computer attitudes as a function of gender and age. A questionnaire with 34 Likert-type items was used in our research. The sample consisted of 659 students from 14 high schools, aged 15–19 years attending the first, the second, the third, and the fourth years of study. The results of the questionnaire were divided into the two dimensions of concrete computer enjoyment and computer anxiety. On the first dimension both younger students and girls have positive attitudes. On the second dimension both younger students and boys have more positive attitudes. Overall, girls have more positive attitudes than boys. This is interesting because in the existing literature there is evidence that boys have more positive attitudes toward computers than girls. Perhaps a change is taking place.
