Profil Regulasi Kognisi Siswa SMP Negeri 2 Palu Dalam Memecahkan Masalah Matematika Ditinjau Dari Gaya Kognitif
Full text linkThis research is a qualitative research aimed to describe the profile of cognitive regulation of the students of VIII C class of SMP Negeri 2 Palu in solving system of equations in two variables viewed from cognitive style. The research subjects were one student belonged to independent field and another student belonged to dependent field. The grouping for obtaining the desired subjects was done by administering GEFT test. The research results show that: (1) in the planning stage, FI was not easily influenced by his environment so that he could convey the information that he knew and was asked to him and he could also develop the steps for solving problems, (2) in the problem solving stage in order to obtain results, FI executed the solving steps already planned, and checked the correctness of the solving steps by analyzing the conformity to the plan, sometimes the subject asked himself because he felt that probably the problems were not in line with the solving steps to be achieved, (3) in the stage of checking the correctness of the solution, FI firstly asked to himself for he felt that probably there might be something illogical, then he matched them manually in order to confirm the results obtained, and when observing his own ways of work, FI decided that the results he obtained were correct, (4) FD was easily influenced by his environment; thus, in the planning stage, he tried to interact with others first and only then he could convey the information that he knew and was asked to him, and he could develop the problem solving steps, (5) in the problem solving stage, FD executed the solving steps, and checked the correctness of the solving steps by analyzing the conformity to the plan, sometimes the subject asked himself because he felt that probably the solving steps were not in line with the solutions to be achieved, and (6) in the stage of checking the correctness of the solution, FD asked to himself for he felt that the solutions obtained were not in line with the objectives being asked, and when observing his own ways of work, FD remained confident with the results he obtained

Pengaruh Model Pembelajaran Inkuiri Dan Gaya Kognitif Terhadap Hasil Belajar Matematika Siswa Kelas VIII SMP Negeri 2 Palu
Full text linkThis study aims to explain the influence of models of inquiry learning and cognitive styles of students towards mathematics student learning achievements. This study is a quasi-experimental design with factorial 2 × 2. The independent variable in this study is the inquiry learning and direct instruction. Cognitive styles of students is divided into two parts, namely the cognitive style field independent (FI) and cognitive style field dependent (FD). The dependent variable is the result of students' mathematics learning. The instrument used was GEFT test used to determine students' prior learning styles koognitif implemented and achievement test used to measure the learning achievements of students after learning mathematics implemented. Samples were students of class VIII SMP Palu Negeri 2 theconsist of 48 students were taken by purposive sampling technique. Data were analyzed using ANOVA analysis of two-path. The results showed that (1) there is an interaction between the model and style koognitif inquiry learning on learning achievement outcomes of mathematics, (2) there is a difference between students' mathematics learning achievements by inquiry learning model and the learning achievements of students who received direct instruction on a group of students who have FI force, (3) there are differences in mathematics learning achievements of students who received the inquiry learning model and who received students learning directly to the student groups which share FD cognitive styles, (4) there are differences in mathematics learning outcomes of students between who have cognitive styles FI and students who have the cognitive styles of students who obtain the FD on inquiry learning, (5) there are differences in mathematics learning achievements students’, among students who have cognitive styles FI with students who have the cognitive style FD on students who received direct instruction
Analysis of the Characteristics of Creative Thinking Students through Mathmatical Posing Problems in terms of Gender Differences
Full text linkThe purpose of this research is to obtain the description of the characteristics of creative thinking of female students and male students through mathematical posing problems. This research uses a qualitative approach in form of case studies based on the categories of the creative thinking according to Balka. The research subjects were chosen based on purposive sampling who willing to provide complete information, had an open nature, and were willing to work together. The two subjects were chosen female students (PR) and male students (LK). The result shows that the characteristics of creative thinking through problem posing PR subjects and LK subjects in the categories: (1) fluency that is, PR subjects and LK subjects were able to raise a number of problems regarding the function of representing the information content provided, (2) flexibility namely PR subjects and LK subjects were able to create many problems that lead to the understanding of functions with different categories of functions, (3) novelty, homework subjects and LK subjects were able to raise new problems when the interview at the same time, which are different from the problems raised when working on written task posing problems, and (4) understanding, that is, the PR subject and LK subject were able to make linkages between ideas about function. Based on these categories, it is concluded that both subjects able to think creatively in raising problems from the information provided

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
