Mathematics teaching as problem solving: A framework for studying teacher metacognition underlying instructional practice in mathematics

The purpose of this exploratory study was to use a teaching as problem solving perspective to examine the components of metacognition underlying the instructional practice of seven experienced and seven beginning teachers of secondary school mathematics. A metacognitive framework was developed to examine the thoughts of teachers before, during and after lesson enactments. Data were obtained through observations, lesson plans, videotapes, and audiotapes of structured interviews during the course of one semester. Data analysis suggests that the metacognition of teachers plays a well-defined role in classroom practice. These findings provide useful insights for researchers and teacher educators in their preservice and inservice mathematics programs.     

Different Reproductive Strategies in Males and Females

The claim for a connection between stressful, unstable childhood environments and early pubertal maturation has only modest empirical support. However, granting the claim for purposes of discussion, and taking an evolutionary perspective, it is argued here that early puberty need not imply a shift from a "quality" toward a "quantity" reproductive strategy. Indeed, for females to make such a shift when they cannot count on secure pair bonding or paternal investment from a male would not serve their inclusive fitness interests; indeed, probably the reverse. Delayed puberty among juveniles with secure, long-continued bonds with the parental generation may serve a different evolutionary function: to minimize inbreeding. Nonevolutionary factors are more than adequate to account for precocious sexuality in individuals with stressful childhood histories.     

A writing curriculum for preschoolers

Conclusion There is no doubt that composing can add much to children's potential for learning at the preschool level. It is critical, however, that the writing should always be for meaningful communication. A play environment is rich with opportunities for meaningful labeling, drawing, and sending of messages. Preschool teachers do not have to succumb to a ditto and workbook approach to writing filtered down from the elementary school curriculum. Older children may not have trouble understanding the purposes for isolate drills, tracing, and copying from the board, but younger children become bewildered by such an abstract instruction. Their writing needs to emerge from drawing and dictating and from first-hand experiences. Their audiences must be immediate.When preschool teachers are sensitized to the values of writing for children and provide a stimulating environment in their classrooms, children will learn to write (and read) easily and naturally and will come to their elementary school experiences with a much more solid foundation for the basic skills.Linda Leonard Lamme is Associate Professor and Chair of the Early Childhood Program and Patricia Denny is a doctoral candidate in early childhood education at the University of Florida in Gainesville.     

A discursive question: Supporting student-authored multiple choice questions through peer-learning software in non-STEMM disciplines

Peer-learning that engages students in multiple choice question (MCQ) formulation promotes higher task engagement and deeper learning than simply answering MCQ’s in summative assessment. Yet presently, the literature detailing deployments of student-authored MCQ software is biased towards accounts from Science, Technology, Engineering, Maths and Medicine (STEMM) subjects, rather than discursive subjects or disciplines where content may contain fewer absolute facts and objective metrics and more nuance. We report on qualitative and quantitative findings from a semester-long deployment of a peer-learning software package (PeerWise) in a 140-student course on Interaction Design. PeerWise enables students to author, rate and comment upon their peers’ MCQ questions. The platform was enthusiastically adopted as a revision aid, yet overall question quality was poor and students expressed difficulty in translating the discursive nature of the course content into MCQs with only one correct answer. In addressing these shortcomings, this paper offers specific recommendations to instructors of more discursive subjects using student-led MCQ authoring platforms, and further, how platforms such as PeerWise may be adapted to better suit disciplines characterised by discursive content. We propose alternative approaches to moderation and two suggestions for potential amendments to the software itself.     

A Multi-Instrument Examination of Preschool Classroom Quality and the Relationship Between Program,Classroom, and Teacher Characteristics

Research Findings: A statewide study of preschool classroom quality was conducted using 3 distinct classroom observation measures in order to inform a statewide quality rating system. Findings suggested that Tennessee preschool classrooms were approaching “good” quality on the Early Childhood Environment Rating Scale–Revised (ECERS-R) and provided a mid-to-high emotional and engaging climate as indicated by the Classroom Assessment Scoring System (CLASS) domains of Emotional Support and Student Engagement. However, classrooms were only minimal on the Early Childhood Environment Rating Scale–Extension and the CLASS Instructional Support domain. Past performance on a state quality rating assessment consistently predicted the current quality of preschool classrooms as assessed by all 3 measures. Lead teachers' education in early childhood and experience were also predictors across quality measures. Practice or Policy: Tennessee preschool classrooms scored higher on the ECERS-R, which is the measure utilized in the statewide Quality Rating and Improvement System. However, classrooms generally performed poorly on measures of instructional support and curriculum. This finding illuminates the importance of the tool selected to measure quality in state quality rating and improvement systems and has implications for policy as states work to build systems that enhance quality in early care and education.     

Applying the High Involvement Framework to Local Management of Schools in Victoria,Australia

ABSTRACT

This article assesses the policy strategy for local management of schools in Victoria, Australia within the high involvement framework for creating high performance organizations. The high involvement framework as adapted to education hypothesizes that a decentralized strategy for improving educational performance requires decentralizing four key resources: power over the budget and personnel functions; information about revenues, expenditures, costs and best practices; knowledge and skills including both technical and business knowledge; and rewards including compensation and other incentives. The framework also includes an instructional guidance framework of curriculum standards and student assessment to those standards, and facilitative principal leadership. Based on two years of data collection at both the state and school levels, focusing on governance, management, finance, and curriculum and instruction, the study found that Victoria's Schools of the Future ranked high on all six variables, and that the decentralization process was working smoothly and major changes were being made in curriculum and instruction when school sites also ranked high on the six variables

     

Biographical Sketch of Frederick G. Kilgour Librarian,Educator, Entrepreneur, 1914–2006

The article traces the career of Frederick G. Kilgour (1914–2006), who is widely recognized as one of the leading figures in 20^th-century librarianship. He founded the Ohio College Library Center (OCLC) and from 1967 to 1981 was its first president and chief executive officer, presiding over OCLC's rapid growth from an intrastate network to an international network. In 1971, under Kilgour's leadership, OCLC introduced an online shared cataloging system and an online union catalog (WorldCat) that is today the world's foremost bibliographic database. In 1978, he created the OCLC Office of Research, and in 1979, under his direction, OCLC launched its online interlibrary loan system. The author of 205 scholarly papers, Kilgour received numerous awards and honors over the course a career that took him from Harvard University Library, to the Office of Strategic Services in World War II, to Yale Medical Library, to OCLC, and finally, to the University of North Carolina at Chapel Hill, where he spent his final years on the faculty of the School of Information and Library Science as a Distinguished Research Professor.

The Language of Laughter: A Quantitative/Qualitative Fusion Examining Television Narrative and Humor

This study utilizes multiple methods to analyze the effects of a laugh track on audience response to four episodes of the classic sitcom, “The Andy Griffith Show.” An experimental design and a narratological approach are used in concert. One of the four episodes stood out quantitatively in terms of perceived humor and overall enjoyment, and was the only episode for which the laugh track had a negative impact. Narratological richness might explain the anomalous episode, as it was found to possess a more complex story structure, higher levels of satire, and other distinctive elements found to have high audience appeal.
