Creating And Solving Model Of Linear Equation Through The Balance At Junior Secondary Class
No full textAlgebra is one of the most difficult subject felt by most students and this strand is just started given to the students at early junior secondary school. Infact, if we can manage the algebra subject wisely and attractively, it can be predicted that the students’ conceptual understanding algebra would be relatively improved.
A study was conducted to the Year 7 students at a Junior Secondary of Laboratory School of UPI. The class was set to learn the linear equation topic by using balance (scales).
Through a weighing activity, the students were able to design linear equation models. They followed a guidelines created by the teacher and researcher. The students were not only able to create linear equation models, but also were able to solve mathematical model of linear equation. By using steps of balance (weighing), finally the students were able to know the weight of a hidden quantity.
A number of teachers were involved in an observation activity which were designed in a lesson study context. Information related to the students’ reaction as well as the teachers’ reaction toward the implementation of creating and designing models of linear equation. The information were analysed qualitatively. The results indicate that introducing the linear equation through the scale (balance) were responded positively by the students. A brief interview with the students indicated that the students fluently could solve linear equation, and find the value of variable which infact as a weight variable. This variable seemed to be the weight of hidden variable as the solution of the linear equation.
Moreover, the students were able to interpret the process of weighing to the form of linear equation, since then the students solved it and found the solution of the problem.
While other teachers as observers at the lesson gave comments that the model teacher had practiced the concept of linear equation by using unusual way of teaching.
Intuitively they solved the linear equation by using step by step of weighing process and determined how much weight of an object. The process of weighing and thinking are parallel to solving a linear equation.
Data of test results regarding the linear equation indicated that the students’ understanding of linear equation improved. The researchers recommend to use the balance (scales) as an alternative to teach the topic of linear equation.

Interview with Endang Turmudi
No full textEndang Turmudi is an Indonesian who studied in Australia on two occasions; in 1988-1990 at Flinders University, and in 1992-1996 at the Australian National University (ANU). On both occasions, he studied on Australian International Development Assistance Bureau (AIDAB) Scholarships. He completed his Masters in Sociology during his time at Flinders University before completing his PhD in the same field at ANU. The interview was conducted in English on 24 April 2014 by Dr. Jemma Purdey and Prof. David Lowe, both of Deakin University, and Dr. Ahmad Suaedy of the Abdurrahman Wahid Centre for Inter-faith Dialogue and Peace at Universitas Indonesia. This set comprises: an interview recording, a timed summary, and a photo

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
