THE DEVELOPMENT OF PROBLEM POSING-BASED MATHEMATICS
INSTRUCTIONAL MODEL TO IMPROVE THE ABILITY OF
CREATIVE THINKING OF STUDENTS AS PROSPECTIVE TEACHERS
(PMP2MK), ALIMUDDIN, YEAR 2012, NUMBER OF PAGES: 74
One of higher level of thinking types that currently attracts keen attention
of cognitive psychologists and becomes educational goal of each country is
creative thinking or creativity. At least, there are two reasons for that, namely 1)
the ability to think creatively is very important for individual to possess, and 2)
creative thinking can be improved through training.
Indonesia as a developing country realizes that to become a developed
country and parallel to other developed countries, it is needed creatively human
resources. Therefore, the ability to think creatively is accounted for national
education goal that is embedded in Ministry Regulation No. 22 Year 2006. Vision
2025 of Ministry of Education and Culture explicitly states that creative is one of
keywords that must be crystallized. Another concern that Ministry of Education
and Culture looks is the existance of policy in case of character of nation culture.
The impact of this policy is that teachers are demanded to develop characterbased-instructional
package.
One of
its
indicators
is
creativity.
Practically,
it is seen that creative ability of teachers and students of all
educational levels are still low. Therefore, it is necessary to conduct a research in
terms of creative thinking. Particularly, students as prospective teachers. It is
because to create a creative student, it is needed a creative teacher, and to create a
creative teacher, the ability of creative thinking of those prospective teachers has
to be improved. In relation to this concern, the author himself conducted a
research entitled The Development of Problem Posing-Based Mathematics
Instructional Model to Improve the Ability of Creative Thinking of Students as
Prospective Teachers (PMP2MK)”. This was aimed at developing problem
posing-based-instructional model to improve the ability of creative thinking of
students as prospective teachers (PMP2MK). In addition, to support the
practicality of this model, it was also developed an instructional package.
Particular targets expected within this study were: (i) Problem Posing-BasedMathematics
Instructional
Model
to
Improve
the
Ability
of
Creative
Thinking
of
Students
as Prospective Teachers (PMP2MK) in the form of model book; (ii)
Prototype of Instructional Package to Support the Practicality of Teaching and
Learning Activity by Using the PMP2MK Model. The intended instructional
package was Lesson Plan (RPP), Student Worksheet (LKM), Student Book (BM),
and Learning Achievement Test. Thus, to attain them, it was designed a
developmental research by referring to as Kemp’s approach.
The research conducted in the first year (year 2012) produced product as
the following: (a) The validated framework prototype of PMP2MK model
consisted of syntax, social system, reaction principle, supporting system, and
instructional and nurturant effects along with underpinning theory of PMP2MK
model; (b) The validated Prototype I of Student Book (BM), Student Worksheet
(LKM), Lesson Plan (RPP), and Creativity Test in Mathematics Problem Solving.
Henceforth, to produce a practical instructional model, it would be
conducted a limited trial. This is planned for the next 2
year of this study.
Whereas, to obtain an effective instructional model, it would be followed up with
an experimental research as a crystallization of implementation of the developed
instructional model. This is planned for the next 3
nd
rd
year of this study
Students' Difficulties in Mathematics Proofs
Full text linkThis qualitative research aimed at investigating difficulties experienced by students in Mathematics Department, State University of Makassar. This study was conducted in Mathematics Education Study Program at Mathematics Department, Faculty of Mathematics and Science, State University of Makassar in academic year 2013/2014. The subjects involved in the research were students of Mathematics Education Study Program in the subjects of Calculus, Trigonometry, and School Mathematics. The subjects were administered in tests concerning mathematics proof. Further, the students’ answers were then categorized into several aspects of difficulties in proving. The research findings showed that there were four categories of difficulties experienced by the students in proving statements in mathematics. The four categories were:(1) the use of symbols which was inappropriate; (2) the lack of students’ understanding about mathematics proof; (3) the difficulties in selecting strategies for mathematics proof; and (4) the lack of understanding of concepts and principles in mathematics.

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
Is Reforming School Mathematics Urgent in Indonesia?
Full text linkABSTRACT - The reformed curriculum for school mathematics in Indonesia has been implemented on a massive scale and it has invited various criticisms. The critics focus mainly on the three reasons for the reform. Firstly, it is believed that the 2004 Curriculum is outdated. Secondly, the reformers say that it could not be implemented effectively by teachers. The third reason is that it has failed to raise the rank of Indonesian students in international assessment programs. In the new curriculum, teachers are given the instructional package complete and ready to implement in the classroom. The development of syllabi and lesson plans is no longer fully assigned to the teachers. With fewer burdens, they are expected to focus on teaching practice and ensuring that the instructional objectives are achieved by their students. With this policy, the teacher empowerment is in question. It has been warned not to treat teachers as mere executors of prescribed syllabi, thus inevitably
limiting their chance to innovate. This paper will examine the reasons for the reform and argue about the importance of continuing professional development in order to produce competent teachers.

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
