Tracing Milin's development of inductive reasoning: a case study
No full textThis study examined how Milin, a nine-year old student, justified his solutions to towers of a variety of heights over a 13 month period. Specifically, it sought to identify heuristics, strategies, and forms of reasoning and argumentation used by Milin in building and supporting his reasoning by partial cases, cases, and then an inductive argument. The research also traced how Milin's ideas traveled to other students. Videotape recordings of Milin's work on towers task and its extensions were analyzed along with his written work, written assessments and the researcher's field notes. The video data consisted of two problem-solving sessions, three individual task-based interviews, a small group assessment, and a whole class discussion. As Milin searched for and sought to justify a global solution for the towers problem, he constructed mathematical ideas by continuously evolving the heuristics and strategies employed. He started by making random towers using a "guess and check" method, where he would randomly create a tower and then compared it with existing towers to identify duplicates. He then proceeded to use local organization strategies to create pairs of towers. This included opposites by color, opposites by inverting and a hybrid strategy. Later, Milin moved towards more refined local organizations such as staircase patterns. When these schemes also proved inadequate to justify a complete solution, Milin developed a family strategy, based on a doubling pattern he had uncovered. This strategy gave him a global organization method. The progression to the global solution was an iterative process in which Milin revisited earlier strategies. Milin also used various forms of reasoning to account for all towers. These included amount of time elapsed between building towers, the concept of "partner" towers, justification by contradiction, cases, doubling rule, and the family strategy. Milin shared his inductive argument with three other students during a small group assessment session. Almost one year later, he re-explained his inductive argument to his partner, Michelle, while working on another task. In turn she shared this argument with other class mates, culminating with one student presenting it to the entire class. The students appeared to understand and retain Milin's strategy better when involved in solving the problem themselves. This case study contributes the body of research in several ways. It documents strategies used by young students to build models of reasoning and argumentation. It also provides support for Davis and Maher's idea that building understanding is not a linear process in that new ideas are built from previous ideas. Finally, this study contributes to the broader collection of case studies from the longitudinal study at Rutgers University.Ed.D.Includes abstractIncludes bibliographical referencesby Manjit Kaur Sra
‘Borrowed borrowings’ traced from Sanskrit to Malay to Malaysian English / Manjit Kaur Balwant Singh
Get PDFThis research investigates the influence of Sanskrit language in Malaysian English tracing the indirect route of the loanwords through Malay as the intermediary language, known as the phenomenon of “borrowed borrowings” in this study. The Sanskrit loanwords found in the online versions of the Malay Newspapers; Berita Harian and Utusan, were examined for their current change in form and function in the process of acculturation by the multicultural speakers and the same procedure was applied to trace these loanwords in the online versions of the Malaysian English Newspapers; the Star and New Straits Times. The Old Malay language was heavily influenced by Sanskrit around the seventh century. Examples include words like Maharddhika ‘prosperous’ borrowed as Merdeka ‘independence’ in Malay which are also found with the same meaning in Malaysian English. These changes were analyzed using Haugen's (1950) theoretical framework of lexical borrowing and recent developments in the field. The categories of loanwords found in the written data were mostly loanwords, derivational and compound blends, and semantic loans. The Malaysian English has been researched for influences of Malay, Chinese and Tamil, the three major languages in Malaysia, but rarely has the indirect influence of the minority groups speaking Indic languages under the Sanskrit umbrella been investigated in its rich tapestry

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
