PENERAPAN PENDEKATAN PEMECAHAN MASALAH DALAM PEMBELAJARAN MATEMATIKA BERDASARKAN PERSPEKTIF KONTRUKTIVIS
Full text linkPenelitian-penelitian yang membandingkan pendekatan kontruktivisme dan pendekatan
tradisional dalam pengajaran matematika seringkali sulit diinterpretasikan. Hal ini disebabkan karena
metode-metode kontruktivis biasanya dimaksudkan untuk menghasilkan hasil belajar yang secara
kualitatif berbeda dengan apa yang dihasilkan oleh metode-metode tradisional. Selain itu kebanyakan
penelitian tentang metode-metode kontruktivis bersifat deskriptif dari pada komparartif. Salah satu
pendekatan pembelajaran yang berbasis kontruktivisme yang dapat dikembangkan dalam proses belajar
mengajar matematika adalah pendekatan pemecahaman masalah. Tujuan penulisan ini adalah
membahas suatu model pendekatan pembelajaran matematika yang berbasis kontruktivisme yang
tersimpul dalam beberapa masalah yaitu; bagaiamana pandangan kontruktovisem dalam pembelajaran,
Bagaimana model pendekatan pemecahamn masalah, sera bagaimana penerapan pendekatan
pemecahan masalah dalam pembelajaran matematika. Untuk lebih meningkatkan hasil belajar siswa
dalam matematika maka pendekatan pemecahan masalah yang didasarkan pada pandangan
kontruktivisme merupakan salah satu alternatif yang dapat dilakukan guru dalam pembelajaran
matematika. Untuk menerapkan pendekatan pemecahan masalah dalam pembelajaran matematika guru
harus lebih berhati-hati dan lihai dalam memilih masalah yang diberikan sebagai panduan
pembelajaran. Pendekatan pemecahan masalah dalam pembelajaran matematika akan menumbuhkan
kemampuan kreatif siswa dalam memecahkan masalah yang mereka hadapi baik dalam pembelajaran
matematika maupun dalam kehidupannya sehari-hari
Description and Analysis of the Competence and Performance of Mathematics Teachers during the COVID 19 Pandemic: A Study Conducted in Gorontalo City
No full textIn the era of the COVID-19 pandemic, online learning has become the main alternative to the learning system taken by schools. The implementation of the online system certainly affects teachers\u27 performance as the frontline in the success of a learning process. In this case, at least the teacher\u27s performance has been directly or indirectly influenced by the learning system that is being carried out. This study aimed to describe and analyze the performance of teachers’ competencies during the COVID-19 pandemic. The study relied on a quantitative descriptive method, and the data were taken from the results of a questionnaire distributed to 89 teachers. The research instrument used questionnaires and interviews, which had previously been tested for validity and reliability. Furthermore, the results of the questionnaires were analyzed based on theories related to teacher performance and theories related to teacher competency development. The result showed that the teachers’ performances with the online learning system during the COVID-19 pandemic were varied and greatly influenced by the competence of the previous teacher. Based on these results, it could be concluded that teachers with high competence had higher performance than teachers with low competence in online learning. Likewise, there was an interaction between the ability of teacher competence and teacher performance in online mathematics learning. Further, the average performance of mathematics teachers in online learning was lower than the performance of teachers who use ordinary learning

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
Developing Students\u27 Mathematical Communication Skill in Junior High School with Various Level of Mathematics Achievement through Generative Learning Model
No full textMathematical communication skill was the missing piece of the mathematics education failure puzzle for centuries despite its central role in learning activities. Built on top of other process skills, the skill was the tool to construct a more comprehensive conceptual understanding by learning math from different perspectives, sharpening other cognitive skills, and providing important feedback about students\u27 understanding. This study observed how the students\u27 mathematical communication skill was correlated with the application of the generative learning model and how this correlation was influenced by various level of the school\u27s academic achievement in mathematics. It employed a fractional 2x2-factorial design, careful non-probability sampling combined with simple random sampling to pick 171 students, and a validated and reliable scoring system to measure communication skills. Based on the results, the students\u27 mathematical communication skill significantly correlates with the application of the generative learning model. The use of factorial design revealed that this correlation was more determined by applying the generative learning model, not by the level of schools\u27 or students\u27 mathematics achievement. Teachers should be more optimistic about using generative learning models to improve mathematical communication skills, even in classes with lower mathematics achievement levels
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
The Effectiveness of Heuristic Vee Model to Improve Students’ Mathematical Problem Solving Skills
No full textMathematical problem solving ability is a key component of students’ cognitive development, enabling them to understand, analyze, and apply mathematical concepts in various real-life situations. Despite its importance, many students struggle with problem-solving due to teacher-centered approaches and the lack of interactive, concept-oriented instructional models. This study aims to examine the effectiveness of the Heuristic Vee learning model in improving students’ mathematical problem-solving skills, particularly in the topic of two-dimensional shapes. The research employed a quasi-experimental method using a Non-Equivalent Posttest-Only Control Group Design. The participants were two seventh-grade classes at MTs Negeri 1 Kota Gorontalo, selected through purposive sampling based on class equivalence and teacher recommendations. The experimental group received instruction using the Heuristic Vee model, which involved problem exploration, concept mapping, and guided reflection, while the control group was taught through the direct instruction method. Data were collected through a post-test consisting of essay questions based on Polya’s four problem-solving stages. All instruments were validated by experts and tested for reliability. Data analysis included descriptive statistics, normality and homogeneity tests, independent t-tests, and effect size measurement. The results showed that the experimental group achieved a higher mean post-test score (49.83) than the control group (31.70), with a significant t-value of 3.458 > 2.002 at the 5% significance level. The effect size (Cohen’s d = 0.89) was categorized as high. These findings indicate that the Heuristic Vee model significantly enhances students’ mathematical problem-solving skills and serves as an effective strategy for promoting student-centered and meaningful mathematics learning
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
