The Use Of Coastal Potency In Learning Mathematics To Enhance Social Skills Of Junior Secondary School Students
No full textSocial skills of junior secondary school students in coastal area are still considered low due to the lack of interaction in mathematics learning. Interaction in coastal class can be done by using coastal potency problem. The objective of this study is to enhance students’ social skills by using coastal potency in learning of mathematics (CCTL). Junior secondary school sample is randomly selected from 10 classes in SMPN 5 Kendari. Two classes are randomly selected from the school sample, experiment class (CCTL) and control class (conventional teaching and learning, CVTL). Instrument that was used in this research is scale of social skills. Data are analyzed by using a qualitative-descriptive technique, one-sample T test, and independent-sample T test. Based on the result of data analysis, it can be concluded that the use of CCTL is significantly better than CVTL in enhancing the students’ social skills, however it’s still in the medium category.

Development Mathematical Problem Solving Problems At Junior High School
No full textThis is development researched which aims at (1) constructing valid and practical mathematical test items based on some problem-solving skills for junior high school students, and (2) finding out the potential effects of such test items after their third or final prototype construction. Those test item were tested to 41 ninth grade students of the state junior high school number 9 in Palembang in academic year 2010/2011. The data were collected through “walk-through” for the test validation by experts. Their validation will result in accurate tests. In addition, the application of small group testing will result in practical potential positive effects for mathematical problem solving skill. Finally, this study reached good level as shown by the mean score “71”.

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
