Fish and Oceanographers,Scholars and Librarians: Researching Nineteenth-Century Russian Women Writers

This article discusses librarianship and literary scholarship as operating under separate paradigms, or ways of looking at the world, and considers the relationship between them. Each of these paradigms, it is suggested, generates distinctive research tools that combined can expand our ability to help Slavic and other Humanities literary researchers.     

Effectiveness of Podcasts Delivered on Mobile Devices as a Support for Student Learning During General Chemistry Laboratories

Chemistry instructors in teaching laboratories provide expert modeling of techniques and cognitive processes and provide assistance to enrolled students that may be described as scaffolding interaction. Such student support is particularly essential in laboratories taught with an inquiry-based curriculum. In a teaching laboratory with a high instructor-to-student ratio, mobile devices can provide a platform for expert modeling and scaffolding during the laboratory sessions. This research study provides data collected on the effectiveness of podcasts delivered as needed in a first-semester general chemistry laboratory setting. Podcasts with audio and visual tracks covering essential laboratory techniques and central concepts that aid in experimental design or data processing were prepared and made available for students to access on an as-needed basis on iPhones^® or iPod touches^®. Research focused in three areas: the extent of podcast usage, the numbers and types of interactions between instructors and student laboratory teams, and student performance on graded assignments. Data analysis indicates that on average the podcast treatment laboratory teams accessed a podcast 2.86 times during the laboratory period during each week that podcasts were available. Comparison of interaction data for the lecture treatment laboratory teams and podcast treatment laboratory teams reveals that scaffolding interactions with instructors were statistically significantly fewer for teams that had podcast access rather than a pre-laboratory lecture. The implication of the results is that student laboratory teams were able to gather laboratory information more effectively when it was presented in an on-demand podcast format than in a pre-laboratory lecture format. Finally, statistical analysis of data on student performance on graded assignments indicates no significant differences between outcome measures for the treatment groups when compared as cohorts. The only statistically significant difference is between students who demonstrated a high level of class participation in the concurrent general chemistry lecture course; for this sub-group the students in the podcast treatment group earned a course average that was statistically significantly higher than those in the lecture treatment group.     

Physical fitness percentiles for Portuguese children and adolescents aged 10–18 years

Abstract

This study aimed to produce age- and sex-specific physical fitness reference data for Portuguese youth; to report the prevalence of youth in the healthy zone of physical fitness according to the FITNESSGRAM^® criteria; to verify the agreement between the Portuguese physical fitness percentiles and the FITNESSGRAM^® healthy zones. In 2008, 22,048 Portuguese children and adolescents (10–18 years) were evaluated. Physical fitness (curl-ups, push-ups, 20-m shuttle run and modified-back-saver-sit-and-reach tests) was evaluated using the FITNESSGRAM^® Test Battery 8.0. Smoothed percentile curves were estimated using Cole’s LMS method. Boys consistently outperformed girls in every physical fitness test, except for the modified-back-saver-sit-and-reach tests. In both sexes and for all physical fitness tests, higher percentile values were observed at older ages. The 50th percentile of all physical fitness tests had the highest accuracy to discriminate between under healthy zone and healthy zone of the FITNESSGRAM^®. Portuguese schools and physical education teachers may considerer the 50th percentile for age and sex or the FITNESSGRAM^® criteria for classifying participants in the healthy zone as acceptable cut-offs, above which youth should be considered fit. These reference values can be used as normative data and for baseline values for subsequent surveillance of the physical fitness of Portuguese youth.     

Impact of compliance with different guidelines on physical activity during pregnancy and perceived barriers to leisure physical activity

Abstract

The aims of the this prospective study were to analyse physical activity (PA) engagement during the first and second trimesters, considering the different guidelines published on PA, to document the individual characteristics associated with the accomplishment of these guidelines and to examine pregnant women’s perceived barriers to leisure PA, using a socioecological framework. A sample of 133 pregnant women in two stages – at 10–12 weeks’ gestation (T1) and 20–22 weeks’ gestation (T2) – were evaluated. PA was assessed by accelerometry during the T1 and T2 evaluation stages. Socio-demographic characteristics, lifestyle factors and barriers to leisure PA were assessed via questionnaire. A large proportion of women (ranging from 32% to 96%) did not reach the levels of PA recommended by the guidelines. There were no significant differences between T1 and T2 with regard to compliance with PA recommendations. A decrease in PA levels from T1 to T2 was noted for all recommendations. No associations were found between participants’ characteristics and adherence to the recommendations in T1 and T2. No significant differences were found in barriers to leisure PA between T1 and T2. The most commonly reported barriers to leisure PA were intrapersonal, not health related. Our results indicate that there were no differences between trimesters regarding compliance of PA recommendations, and perceived barriers were similar in both trimesters.     

The relationship between students’ small group activities,time spent on self-study,and achievement

The purpose of this study was to investigate the relationship between the contributions students make to the problem-based tutorial group process as observed by their peers, self-study time and achievement. To that end, the Maastricht Peer Activity Rating Scale was administered to students participating in Problem-Based Learning tutorial groups. With this rating scale students had to rate the constructive, collaborative and motivational activities of their peers within the tutorial group. In addition, time spent on self-study was measured with a self-estimation method and achievement was measured with a unit test and a group assignment. A causal model of these variables was developed, in which the three types of activities were assumed to affect time spent on self-study, which would in turn affect unit test scores and group assignment scores. A structural equation modeling analysis indicated acceptable model fit. Especially apparent was the evidence for the causal relations between a student’s constructive activities and his/her unit test score and between a student’s collaborative activities and the group assignment score. On the other hand, time spent on self-study was not affected by the students’ contributions, nor did it have an effect on the unit test score. These results suggest that there are indeed causal relations between a student’s contributions to the tutorial group process and achievement.     

Becoming a teacher: student teachers’ experiences and perceptions about teaching practice

In an attempt to build a more comprehensive and holistic understanding of the complexity, dynamics and idiosyncrasies involved in becoming a teacher, this study focussed on the experiences of 295 student teachers. Their feelings, cognitions and perceptions regarding teaching practice were analysed using the short version of the Inventory of Experiences and Perceptions of the Teaching Practice. Results emphasise some of the difficulties experienced during this period (e.g., stress, sense of weariness and ‘vulnerability’), as well the positive perceptions of these student teachers regarding their growing knowledge and skilfulness, as well as their sense of efficacy, flexibility and spontaneity in their performance and interactions. Their perception of their accomplishments in achieving reasonable levels of acceptance and recognition within the school community and their positive evaluation of the guidance and support provided by their supervisors are also emphasised. Differences were found – in terms of gender and graduate course background – in the way these student teachers experienced some aspects of teaching practice.     

De-Mystifying the U.S. News Rankings: How to Understand What Matters,What Doesn't and What You can Actually Do About It

College rankings present challenges and opportunities for higher education marketers. Statistical analysis of data on the national universities reveals which measures are associated with peer assessment scores, whether it is possible to influence the score, and what underlying factors are present. Marketers can use the findings to counsel senior leaders and position their institutions more effectively with key constituencies.     

Ideologies and utopias: education professionals' views of inclusion

The paper addresses the contrast between different elements in thinking about the appropriate educational placement for children with special educational needs. In particular, it is concerned with the tension between the widespread expressions of support for the principle of inclusion and a continuing level of support for separate special school provision. Evidence from interviews with education officers and headteachers of both special and mainstream schools in the UK demonstrates the support for inclusion as an ideal but also the relatively limited influence of such an ideal on education policy. Considerable reservations were expressed about the feasibility of inclusion, based on the types and severity of children's difficulties and the capacity of mainstream schools to meet them. Contrasting with support for inclusion was a set of views which stressed the primacy of meeting children's individual needs as overriding an ideological commitment to inclusionist ideals. Themes within utopian thinking, in particular, the distinction between hope and desire and the different functions which can be served by utopian ideals, are used to explore tensions and contradictions in the interview responses and in educational thinking more generally.     

Promoting Science Outdoor Activities for Elementary School Children: Contributions from a research laboratory

The purposes of the study were to analyse the promotion of scientific literacy through practical research activities and to identify children's conceptions about scientists and how they do science. Elementary school children were engaged in two scientific experiments in a marine biology research laboratory. A total of 136 students answered a questionnaire about their previous habits towards science and carried out the following actions: (1) a guided visit to the laboratory, (2) a brief presentation of the research theme, (3) the development of two experiments, and (4) a questionnaire about the experiments and science conceptions. The research methods included observation, document analysis, and content analysis of the answers to the questionnaires. Additionally, each visit was video recorded in order to design learning materials. The results revealed that most of the pupils were able to follow every stage of experimentation. However, some of them misinterpreted results and conclusions. One implication of the study is that this type of outdoor activity is extremely important to promote meaningful science learning in children, but more care should be taken in practical science activities so that children can overcome some common difficulties when performing scientific inquiry.     

Single‐sex schooling and labour market outcomes

One quarter of the 1958 British Birth cohort attended single‐sex secondary schools. This paper asks whether sex‐segregated schooling had any impact on the experience of gender differences in the labour market in mid‐life. We examine outcomes at age 42, allowing for socio‐economic origins and abilities measured in childhood. We find no net impact of single‐sex schooling on the chances of being employed in 2000, nor on the horizontal or social class segregation of mid‐life occupations. But we do find a positive premium (5%) on the wages of women (but not men), of having attended a single‐sex school. This was accounted for by the relatively good performance of girls‐only school students in post‐16 qualifications, not by the wider range of subjects studied by both girls and boys at single‐sex schools. Men’s labour market attainments were more closely related to attending private schools and to parental class, suggesting that the intergenerational transmission of advantage, while not related to coeducation, is related to gender.
