The effect of using Problem based Learning Strategy in Teaching Biology on Academic Achievements and Learning Retention among 1oth Grade Female Students
Get PDFهدفت هذه الدراسة إلى تقصي أثر استخدام استراتيجية التعلم المبني على المشكلة في تدريس الأحياء على التحصيل الدراسي، والاحتفاظ بالتعلم لدى طالبات الصف العاشر.
ولتحقيق أهداف الدراسة تم تقسيم عينة الدراسة إلى مجموعتين: ضابطة، درست بالطريقة السائدة، وعدد طالباتها (61) طالبة، ومجموعة تجريبية درست باستخدام استراتيجية التعلم المبني على المشكلة وعدد طالباتها (62) طالبة. كما تم تصميم اختبار مكون من (30) فقرة في صورته النهائية، يهدف إلى قياس تحصيل الطالبات في مادة الأحياء، والاحتفاظ بالتعلم. وقد تم التحقق من صدقه بعرضه على مجموعة من المحكمين في تدريس الأحياء، كما تم حساب ثباته باستخدام معادلة كرونباخ ألفا للاتساق الداخلي، وقد كان معامل ألفا يساوي (0.76)، والذي يعد مناسبا لغرض الدراسة.
أشارت نتائج الدراسة إلى تفوق أداء المجموعة التجريبية التي درست باستخدام استراتيجية التعلم المبني على المشكلة على المجموعة الضابطة التي درست بالطريقة السائدة في التحصيل الدراسي المباشر. كذلك أشارت نتائج الدراسة إلى وجود فروق دالة إحصائيا بين المجموعتين في الاحتفاظ بالتعلم ولصالح المجموعة التجريبية التي درست باستخدام استراتيجية التعلم المبني على المشكلة.
وخلصت الدراسة إلى عدد من التوصيات والمقترحات في ضوء ما أسفرت عنه من نتائج من ضمنها تشجيع المعلمين سواء معلمي الأحياء أو معلمي مواد العلوم الأخرى على استخدام استراتيجية التعلم المبني على المشكلة في تدريسهم، وتدريبهم عليها، والقيام بمزيد من الدراسات والبحوث في هذا المجال على صفوف ومتغيرات تعليمية - تعلمية أخرى.The study aimed at identifying the effect of using problem
based learning strategy on pupils' achievement and learning retention
of the lOth grade female pupils.
To achieve the above aim, the sample was divided into two
groups: control group taught by normal method and it consisted of
( 61) students. The second group was an experimental group taught by
problem based learning strategy and it consisted of (62) students.
A multiple choice test consisted of (30) items in its final
version was used to investigate pupils' achievement and learning
retention. The test was validated through a panel of judges and the
reliability was calculated by Alfa Cronbach for internal consistency
method which gives the value of(0.76).
The results showed that there was a statically significant
difference in the mean scores between the experimental group and the
control group in achievement in favor of the experimental group.
Moreover, the results showed there was a statically significant
difference in the mean scores between the experimental group and the
control group in retention in favor of the experimental group.
A number of recommendations and suggestions were proposed
in light of the above results, such as encouraging science teachers to
use problem based learning strategy in their teaching, training these
teachers how to use such strategy in their teaching and conducting
more research in this area at different class levels and for other
teaching and learning variables
The Image of Omani Teachers as Viewed by Segments of Society: An Analytical Descriptive Study
Get PDFThis study aimed to identify the image of Omani teachers as viewed by other segments of society. The study sample consisted of 1196 members of Omani society from different sectors of the following Omani governorates: Muscat, Al-Dakhlyha, North Al-Sharqyia, South Al-Sharqyia, North Batinah, and South Batinah in academic year 2014/2015. To gather the data, a questionnaire consisting of 32 items and two open ended questions was used. The validity of the instrument was checked by a panel of experts. The reliability of the questionnaire was checked for internal consistency using Cronbach's alpha (a = 0.93). The overall results showed a positive image of Omani teachers as they are seen to play a positive role in the development of society and hold a message in life to pass to their students. In addition, the results showed statistically significant differences due to gender and the nature of their jobs. In addition, the results showed no significant differences due to having kids in school. Based on the findings, the researcher concluded with a number of suggestions and recommendations
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
