Developing essay writing skills: an evaluation of the modelling behaviour method and the influence of student self-efficacy

Social cognitive learning theory has shown that observational learning positively influences essay writing development in high-school students, and that self-efficacy impacts on motivation. This study investigated the relative contribution of model observation, model evaluation, post-submission feedback, and factors relating to self-efficacy, as measured through academic confidence, in the essay writing development of 142 university students. The research compared students’ essay marks between two semesters in order to explore whether observational learning had an impact on the development of the complex skills involved. The results revealed that all students benefit from traditional feedback and higher levels of self-efficacy when developing their essay writing performance. Underperforming students particularly benefited from actual essay writing. However, contrary to the predictions drawn from the literature, students in this study did not appear to benefit from observational learning when developing their skills. Limits to social learning theory are discussed.     

Touchstones as sprezzatura: the significance of attachment to teacher literary formation

A touchstone is a smooth dark stone that, when rubbed against gold and silver, proves the metal's quality. Figuratively, it has come to signify ‘that which serves to test or try the genuineness of anything’ (Oxford English Dictionary). Here I consider why certain literary ‘touchstones’ of teachers are more formative than others. This leads to an exploration of the close association between the aesthetics of literary response and the sprezzatura of childhood reading. The pedagogical question of involving teachers and teacher educators in critical reflection on their practices should begin with these formative stories.     

Using item response theory to describe the Nonverbal Literacy Assessment (NVLA)

The Nonverbal Literacy Assessment (NVLA) is a literacy assessment designed for students with significant intellectual disabilities. The 218‐item test was initially examined using confirmatory factor analysis. This method showed that the test worked as expected, but the items loaded onto a single factor. This article uses item response theory to investigate the NVLA using Rasch models. First, we reduced the number of items using a unidimensional model, which resulted in high levels of test reliability despite decreasing the number of questions, providing the same information about student abilities in less time. Second, the multidimensional analysis indicated that it is possible to view the NVLA as a test with four dimensions, resulting in more detailed information about student abilities. Finally, we combined these approaches to obtain both specificity and brevity, with a four‐dimensional model using 133 items from the original NVLA.     

The Stability of IRT b Values

This study investigated possible explanations for an observed change in Rasch item parameters (b values) obtained from consecutive administrations of a professional licensure examination. Considered in this investigation were variables related to item position, item type, item content, and elapsed time between administrations of the item. An analysis of covariance methodology was used to assess the relations between these variables and change in item b values, with the elapsed time index serving to control for differences that could be attributed to average or pool changes in b values over time. A series of analysis of covariance models were fitted to the data in an attempt to identify item characteristics that were significantly related to the change in b values after the time elapsed between item administrations had been controlled. The findings indicated that the change in item b values was not related either to item position or to item type. A small, positive relationship between this change and elapsed time indicated that the pool b values were increasing over time. A test of simple effects suggested the presence of greater change for one of the content categories analyzed. These findings are interpreted, and suggestions for future research are provided.     

Students’ views of uncertainty in formal and personal science

Background: Uncertainty is a crucial element of scientific knowledge growth. Students should have some understanding of how science knowledge is developed and why scientific conclusions are considered more or less certain than others. A component of the nature of science, it is considered an important aspect of science education and allows students to recognize the limitations of scientific research.

Purpose: This study examined Grades 5 and 9 students’ views of uncertainty in their personal scientific research and the formal scientific research of professionals.

Sample: This study included 33 students in Grade 5 (n = 17) and Grade 9 (n = 16). The students were recruited from a charter school that emphasised inquiry instruction.

Design and methods: Data were collected through interviews. Students were asked their views of their inquiry-based projects and their views of professional science.

Results: Interview data and statistical analyses indicated that students recognized uncertainty in personal science, which varied across elements of the scientific process. Additionally, their views of uncertainty in formal science tended to change across grades and knowledge of uncertainty in personal and formal science were positively correlated.

Conclusion: These findings offer insights into the processes by which students come to understand uncertainty in science and point to ways of fostering such knowledge through teaching practices.     

Preservice teachers’ articulated noticing through pedagogies of practice

Elementary preservice teachers at six universities engaged in a task that provided them opportunities to articulate their professional noticing within video representations, written decompositions, and animated approximations of practice. The preservice teachers’ written accounts indicated that a majority attended to students or student thinking; however, when asked to illustrate their noticing through animation, focus shifted to the classroom teacher. Findings indicate the extent to which preservice teachers articulated specific mathematics concepts within and across pedagogies of practice and highlight the critical importance for selecting and utilizing multiple types of tasks to better understand preservice teacher noticing. Implications for eliciting and supporting preservice teacher noticing are discussed.     

Appreciated abroad, depreciated at home. The career of a radiochemist in Norway: Ellen Gleditsch (1879-1968)

Ellen Gleditsch (1879-1968) became Norway's first authority on radioactivity and the country's second female full professor. From her many years abroad--in Marie Curie's laboratory in Paris and at Yale University in New Haven with Bertram Boltram--she became internationally acknowledged and developed an extensive personal and scientific network. In the Norwegian scientific community she was, however, less appreciated, and her appointment as a professor in 1929 caused controversy. Despite the recommendation of the expert committee, her predecessor and his allies spread the view that Gleditsch was a diligent but outdated researcher with little scientific promise-a view that apparently persists in the Norwegian chemical community today. In addition to her scientific work, Gleditsch acquired political influence by joining the International Federation of University Women in 1920; she later became the president of both the Norwegian section and the worldwide organization. She worked in particular to establish scholarships enabling women to go abroad.
