Time series analysis of a Web search engine transaction log

In this paper, we use time series analysis to evaluate predictive scenarios using search engine transactional logs. Our goal is to develop models for the analysis of searchers’ behaviors over time and investigate if time series analysis is a valid method for predicting relationships between searcher actions. Time series analysis is a method often used to understand the underlying characteristics of temporal data in order to make forecasts. In this study, we used a Web search engine transactional log and time series analysis to investigate users’ actions. We conducted our analysis in two phases. In the initial phase, we employed a basic analysis and found that 10% of searchers clicked on sponsored links. However, from 22:00 to 24:00, searchers almost exclusively clicked on the organic links, with almost no clicks on sponsored links. In the second and more extensive phase, we used a one-step prediction time series analysis method along with a transfer function method. The period rarely affects navigational and transactional queries, while rates for transactional queries vary during different periods. Our results show that the average length of a searcher session is approximately 2.9 interactions and that this average is consistent across time periods. Most importantly, our findings shows that searchers who submit the shortest queries (i.e., in number of terms) click on highest ranked results. We discuss implications, including predictive value, and future research.     

The effect of secondary school study skills preparation on first‐year university achievement

Although many studies have revealed the importance of study skills for students' first‐year performance and college retention, the extent of the impact of study skills preparation on students' academic achievement is less clear. This paper explores the impact of pre‐university study skills preparation on students' first‐year study experiences, academic achievement and persistence. The setting for this study is a large law school in the Netherlands which attracts students from more than 100 schools for secondary education. The results show that the perceived study skills preparation concerning time management and learning skills does have a positive impact on college students' first‐year study behaviour and academic achievement. However, the study also shows that the impact of perceived college preparation is far less important for college retention than other factors such as satisfaction about the chosen degree programme and tutorial attendance.

How teachers’ beliefs about learning and teaching relate to their continuing professional development

Teachers’ continuing professional development (CPD) can improve teacher quality and teaching practice, yet teachers differ greatly in the extent to which they engage in CPD. In extensive research into which factors affect teachers’ participation in CPD, the effects of teachers’ beliefs have received limited attention, despite their strong influences on people’s working and learning. Teachers’ beliefs about learning and teaching in particular influence their teaching practices. Does a comparable relationship exist between these beliefs and teachers’ own learning or participation in CPD? To explore this relationship, 260 Dutch secondary school teachers completed a survey that focused on the teachers’ student-oriented and subject matter-oriented beliefs, as well as on teachers’ updating, reflective and collaborative activities. Because teachers’ characteristics reflect both belief dimensions, this study relied on cluster analysis, which revealed three distinct belief profiles. These results indicated that teachers’ beliefs about learning and teaching relate to their participation in CPD: the more a teacher’s profile is student oriented and subject matter oriented, the higher his or her participation in CPD. The results have implications for enhancing teachers’ reflections on their beliefs about learning and teaching, in conjunction with participation in CPD.     

Individualization,the new political spectrum and the functions of adult education

The ambivalences of individualization have triggered a new discourse on social policy. The central themes in this discourse are the promotion of social integration and participation. This new political discourse has thwarted the old left‐right continuum and given rise to a new political spectrum. On one side of this new political spectrum are political perspectives that emphasize integration, solidarity, community. The authors call these collectivistic perspectives. On the other side of the spectrum are perspectives that interpret individualization as the triumph of freedom of choice for individuals. The authors call these the individualistic perspectives. They then describe the spectrum between collectivism and individualism in detail and link each perspective to programmes in adult education typical of such a perspective. In conclusion, the authors summarize their own position in respect of the mission of adult education.     

Integrating Physics and Literacy Learning in a Physics Course for Prospective Elementary and Middle School Teachers

The ability to listen closely, speak clearly, write coherently, read with comprehension, and to create and critique media offerings in science contexts is essential for effective science teaching. How might instructors develop such abilities in a physics course for prospective elementary and middle school teachers? We describe here such a course, involving collaboration among physics, science education, and literacy faculty members and two graduate assistants. Meeting twice a week for 10 weeks, the course emphasized questioning, predicting, exploring, observing, discussing, writing, and reading in physical science contexts. We report common themes about aspects that fostered or hindered science and literacy learning, changes in views about science teaching and learning, and positive shifts in interest in science and intended teaching practices.     

Towards graduateness: exploring academic intellectual development in university master’s students

Our research aims to contribute to the body of knowledge on graduateness by proposing a model that explicates the expected level performance of graduates. In this study, the model is elaborated for 3 graduateness domains: reflective thinking, scholarship, and moral citizenship. We used data on students’ perceived abilities in these domains that were collected at both the beginning and end of 1-year master’s programmes in 3 faculties at a research-intensive university. The model appears to be suitable for investigating students’ academic intellectual development. Not all students appeared to achieve the expected level of graduateness by the end of the master’s programme. However, the results revealed an increase in the proportion of students meeting the thresholds for graduateness. The students’ reports reveal growth in reflective thinking and scholarship during the master’s programme.     

Cognitive abilities of Kenyan children in relation to nutrition, family characteristics, and education

The purpose of this study was to determine whether nutritional factors, family characteristics, and the duration of schooling were associated with cognitive and attentional capacities in children growing up in rural Kenya. Food intake was measured by direct observation and weighment twice monthly over the course of a year. Families were characterized in terms of socioeconomic status and the literacy of the parents. Children who were better nourished had higher composite scores on a test of verbal comprehension and the Raven's matrices. Better-nourished females were more attentive during classroom observations than malnourished female schoolchildren. Family characteristics and duration of school participation were associated with cognitive abilities for both boys and girls. For the children considered as a group, cognitive scores were best predicted by a combination of factors including duration of schooling, food intake, physical stature, and SES.
