Beyond SumBasic: Task-focused summarization with sentence simplification and lexical expansion

In recent years, there has been increased interest in topic-focused multi-document summarization. In this task, automatic summaries are produced in response to a specific information request, or topic, stated by the user. The system we have designed to accomplish this task comprises four main components: a generic extractive summarization system, a topic-focusing component, sentence simplification, and lexical expansion of topic words. This paper details each of these components, together with experiments designed to quantify their individual contributions. We include an analysis of our results on two large datasets commonly used to evaluate task-focused summarization, the DUC2005 and DUC2006 datasets, using automatic metrics. Additionally, we include an analysis of our results on the DUC2006 task according to human evaluation metrics. In the human evaluation of system summaries compared to human summaries, i.e., the Pyramid method, our system ranked first out of 22 systems in terms of overall mean Pyramid score; and in the human evaluation of summary responsiveness to the topic, our system ranked third out of 35 systems.     

A well-started beginning elementary teacher’s beliefs and practices in relation to reform recommendations about inquiry-based science

Given reform recommendations emphasizing scientific inquiry and empirical evidence pointing to the difficulties beginning teachers face in enacting inquiry-based science, this study explores a well-started beginning elementary teacher’s (Sofia) beliefs about inquiry-based science and related instructional practices. In order to explore Sofia’s beliefs and instructional practices, several kinds of data were collected in a period of 9 months: a self-portrait and an accompanying narrative, a personal philosophy assignment, three interviews, three journal entries, ten lesson plans, and ten videotaped classroom observations. The analysis of these data showed that Sofia’s beliefs and instructional practices were reform-minded. She articulated contemporary beliefs about scientific inquiry and how children learn science and was able to translate these beliefs into practice. Central to Sofia’s beliefs about science teaching were scientific inquiry and engaging students in investigations with authentic data, with a prevalent emphasis on the role of evidence in the construction of scientific claims. These findings are important to research aiming at supporting teachers, especially beginning ones, to embrace reform recommendations.     

Learning and the new growth theories: policy dilemma

This paper identifies and interprets the six essential steps in the development of neoclassical growth theory from the Solow–Swan model to the new growth theory models of sustained endogenous growth driven by learning (e.g., [Romer, P., 1990. Endogenous technological change. Journal of Political Economy, 98 (5): S71–S102]). The success of that modeling exercise is based on the specification of selected assumptions about learning in industry. The practical shortcomings of the exercise are highlighted by the various and conflicting policy implications arising from the selection of attributes. It is concluded that better policies may follow from basing assumptions of learning behavior on the understanding of the process and strategy of learning that is emerging from institutional and evolutionary work.     

Summative and Formative Style Anatomy Practical Examinations: Do They Have Impact on Students’ Performance and Drive for Learning?

Anatomical knowledge is commonly assessed by practical examinations that are often administered in summative format. The format of anatomy practical examination was changed at the Lee Kong Chian School of Medicine in Singapore from summative (graded; must pass) to formative (ungraded; no pass/fail) in academic year (AY) 2017–2018. Both assessment formats were undertaken online, but the formative mode used a team-based learning activity comprising individual and team assessments. This gave an unique opportunity to investigate: (1) the impact of two different online assessment formats on student performance in practical examination; (2) the impact of new formative practical examination on students’ performance in summative examinations; and (3) students’ opinions of these two practical examination formats. The class of 2021 perceptions was obtained as they experienced both formats. A retrospective cohort study was also conducted to analyze the Year 2 students’ performance in anatomy practical and year-end summative examinations of cohorts AY 2015–2016, AY 2016–2017 (summative format), and AY 2017–2018 (formative format). There were no significant differences in students’ performance between two practical examination formats. The cohort who experienced the formative format, performed significantly better in summative examinations (mean ± SD: 82.32 ± 10.22%) compared with the cohort who experienced the summative format (73.77 ± 11.09%) (P < 0.001). Students highlighted positive features of the formative practical examination, including team reinforcement of learning, instant feedback, and enhanced learning. These findings indicate that students continue to study for anatomy practical examination without the need for external drivers. The team-based learning style practical examination enhances students’ performance in summative examinations.     

Aggression toward teachers,interaction with school shooting media,and secondary trauma: Lockdown drills as moderator

The purpose of the present study was first to investigate whether both teacher-reported classroom aggression (ATT) and teachers’ interaction with school shooting media (ISSM) are predictors of teachers’ secondary trauma related to school shootings (STSS) and to second, consider how participation in lockdown drills may moderate these relationships. Two measures were created to understand the levels of aggression teachers report occurs in their classrooms and to understand how teachers interact with media related to school shootings. Both ISSM and ATT were associated with higher levels of STSS. Lockdown drills did not appear to interact with these relationships to either strengthen or weaken them. Considering the importance of teachers’ well-being and how it influences their ability to be effective teachers, continued investigation is warranted.

Developing and articulating pedagogic principles: A case study of early childhood teacher trainees learning to use pedagogic documentation techniques

ABSTRACT

This research examines the development and articulation of pedagogic principles and the process of using pedagogic documentation techniques by early childhood teacher trainees in a university teacher training program (BA Primary Education leading to Qualified Teacher Status) in London, England. The study draws on the perspectives of students in the second year of the teacher training program, and the tutor for the module, as well as documentary analysis of 14 pedagogic documentation panels that were produced by the teacher trainees. The research demonstrates how the development and articulation of pedagogic principles is enabled by the reflective and collaborative practice of photography, dialogue, narrative, and metaphor. Findings can be used to better understand how teacher trainees engage with pedagogic principles while they learn how to use the techniques of pedagogic documentation.
