Development of Student Worksheets Based on Constructivism in Mathematics Learning for Grade VII at SMP Pertiwi 2 Padang
No full textThis research is motivated by the still low level of attention and participation of students during the process mathematics learning. Media used to support learning only use the Mathematics package book for class VII independent curriculum and learning is still centered on the teacher. Based on these problems, researchers developed mathematics Student Worksheets based on constructivism on quadrilateral material for class VII SMP Pertiwi 2 Padang. The aim of the research is to produce a valid and practical constructivism-based mathematics worksheet on rectangular plane material. This type of research is development research. In this study, researchers used research procedures by Borg and Gall. Data used to assess the validity of the media were obtained from validation sheets by worksheets characteristic and language experts and design experts, while the data used to assess practicality is obtained from the sheet student practicality. The worksheets developed contains flat material rectangular . The product validity assessment was carried out by two lecturers and declared valid for use from the aspects of worksheets characteristics, language and design. Practicality assessment from students\u27 practicality questionnaire at the test stage try with practicality criteria of 77.46% based on ease of use use, ease of understanding, and time required. So it can be concluded that the constructivism-based worksheets in class VII mathematics learning at SMP Pertiwi 2 Padang is valid and practical to use as a mathematics learning medium. Based on the results of this research, researchers suggest that this worksheets can be used as an alternative media by teaching staff.
 
Analysis of Student Errors in Solving Word Problems using Polya Steps
No full textThis research was motivated by the many difficulties experienced by students in the mathematics learning process which had an impact on the occurrence of errors in working on mathematics story problems. These errors need to be known so that it is easier to find solutions so that these errors can be minimized. This research aims to determine the types and causes of errors made by students in solving mathematics story problems on single interest and compound interest materials using Polya\u27s steps. This research method is qualitative with descriptive research type. The research subjects consisted of 2 students from 13 class XI TKP SMKN 1 Pariaman students, with the criteria being 1 student each from the medium group and 1 student from the low group. Data collection techniques include tests and interviews. The results of the research show that the percentage of errors made by students in solving mathematics story problems on single interest and compound interest material using Polya steps is: in question number 1, the biggest error made in the step of understanding the problem was 23.08%. Question number 2, the biggest error made during the rechecking step was 15.38%. In question number 3, the biggest mistake made in the step of understanding the problem was 19.23%. The factors that cause students to make mistakes include, not being used to writing information on questions using their own words, not writing down what they know and what is asked in the question correctly, not focusing when working on questions, not being careful in carrying out the calculation process, not being used to checking again, and rushing through the settlement process
Pengembangan LKS Berbasis Problem Based Learning Pada Materi Sistem Persamaan Linear Dua Varibel Di Kelas VIII
No full textThis research was motivated by students lacking enthusiasm and being less active in learning mathematics. One effort to overcome this problem is to develop problem based learning worksheets because they can help teachers in developing student centered learning which makes students active in learning. This type of research is development using the ADDIE development model which has 5 stages, namely analysis, design, development, implementation and evaluation. Product trials were carried out at SMP N 1 Kuantan Hilir. The research subjects were 10 students in class VIII.2. The research results showed that problem based learning worksheets were valid by two validators. Worksheets based on problem based learning were declared practical with a score of 63%. So that problem based learning worksheets are valid and practical. From the research, it is recommended that teachers use LKS based on problem based learning as teaching materials and several shortcomings during the research include: (1) in groups of students only a few people are looking for answers and apart from that they only see answers from their group friends (2) students tended to tell stories during learning (3) the researcher did not take all the subjects in the class (4) when filling in the practicality sheet the students were not honest

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
