Investigating the Effectiveness and Teachers’ Perceptions of Rigorous Curriculum Design for Project-Based Learning Implementation on Middle School Science Students’ Achievement and MAP scores in a Private School in Abu Dhabi, UAE
No full textBackground and Purpose: Project-based learning (PBL) is an active student-centered instructional that has been explored in various contexts of schooling over the years. While the majority of the reviewed studies were conducted in North America, Europe, and part of Western Asia, very limited studies were conducted in the MENA region. Achieving proficiency in science requires students to learn through a high-quality curriculum that allows them to participate in authentic practices resembling scientists’ work that enhance their skills, sustain motivation, and increase their achievements. Therefore, the Rigorous Curriculum Design (RCD) framework was adopted in this study to develop PBL curriculum units that align standards, instruction, and assessments. Since countries’ educational systems accountability is currently evaluated based on student’s achievements in external benchmark assessments and while students are still underperforming in benchmark assessments particularly Measure of Academic Progress (MAP) in the United Arab Emirates (UAE) this study aimed to Investigate the Effectiveness and Teachers’ Perceptions of RCD for PBL Implementation on Middle School Science Students’ Achievement and MAP scores in a Private School in Abu Dhabi, UAE.
Methods: Guided by the perspectives of Vygotsky’s social constructivist theory and Dewey’s experiential learning theory, an explanatory sequential mixed method design was used in this study. Science Standards Knowledge Test (SSKT), teachers’ questionnaires, MAP results, and teachers’ interview questions were adopted as tools for collecting data. Participants included N=304 middle school students, mostly Emiratis, middle school science teachers N=25, and six middle school science teachers that were purposively selected and interviewed as they implemented the RCD-PBL curriculum units. Descriptive and inferential statistics were used to analyze the results of the quantitative tools while thematic analysis was used for the qualitative data.
Results: The findings revealed several significant results: 1) implementing RCD-PBL has increased grades 6 to 8 students’ Pre-Posttest results in the SSKT in the experimental group compared to the control group. 2) implementing RCD-PBL has increased the students’ spring 2022 results in the MAP science exam for the experimental group compared to the control group for grades 6 to 8. 3) Teachers’ perceptions have evolved whereby they are more confident about the implementation of the RCD-PBL. They indicated how their involvement, understanding of the RCD-PBL, competencies, knowledge, and professional development were very important factors that influenced the curriculum design process and its successful implementation. In addition to the type of assessment (GRASPS), resources, delivery time, leadership, and parental involvement and support. Teachers have indicated that RCD-PBL curriculum units provided a coherent, cumulative, and well-sequenced enriched curriculum that helped improved and achieved the quality of education needed for their students and had a positive effect on improving their results in science benchmark exams.
Implications, contributions, and recommendations: It was evident that students were underperforming in benchmark exams due to the lack of a high-quality curriculum that enhances their skills and ensures their engagement in science. In addition, teachers are facing many challenges as they struggled to figure out the best ways to address the standards, plan, and implement PBL in UAE. The isolation that they faced as pioneers in implementing such an approach peripheral to the curriculum in K-12 education was also evident. Therefore, investigating the effectiveness of implementing PBL science curriculum units using the RCD while grasping teachers’ perceptions towards their involvement in the development and implementation process could enhance all UAE students’ results in benchmark exams and help all educational leaders in the country to reach the UAE National Agenda 2031 and 2071. Therefore, further research is suggested with regards to monitoring the effectiveness of RCD-PBL on MAP scores for more than one academic year, investigating the effectiveness of such curricula in different subjects, grade levels, and impact on genders, increasing parental involvement, and examining their perceptions towards such curriculum desig
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
