PENGEMBANGAN MODUL KOMPOS TERINTEGRASI KONSEP KIMIA SEBAGAI BAHAN AJAR UNTUK SISWA PROGRAM AGRIBISNIS TANAMAN PERKEBUNAN (ATP) SMKN ACEH TIMUR
Full text linkLearning curriculum in a vocational school combines the adaptive, normative and productive subject group. The adaptive, normative and productive subject groups are expected to be mutually supportive and complementary, in fact the group of subjects did not support each other. The purpose of this study is to develop a learning module for productive subject package (composting techniques) which is integrated by the concept of chemistry as one of the adaptive subjects in vocational school, another purpose of this study is to collect the responses of teachers and students on the module, the module quality assessment by experts, assessment of the portion of chemical concepts that integrated in the module by specialists and module effectivity test. The development of module is using the one of instructional development model in teaching materials development known as ADDIE model (analysis, design, development, implementation, evaluation). The results showed that 92% of teachers responded positively to the module, 85% of students responded positively . While the negative resposes from teacher wes 8% and 15% for student responses. The module quality assessment indicate score 3.36 which the criteria "good" and the expert assessment of chemical concepts are integrated in the module is 70% - 80%. The effectivity of module using student test results indicate the average grades is 92 which criteria "very good". The results suggest that the effectivity of the module is very good for learning

Implementasi Modul Kimia Pangan Melalui Pendekatan Etnokimia di SMK Negeri Aceh Timur Program Keahlian Tata Boga
Full text linkImplementation of learning modules is part of the development proses of ethnochemistry based modules. This study aims to find out the effect of the implementation of ethnochemical-based food chemistry modules on students through analysis of student understanding of integrated chemistry concepts, analysis of the effectiveness of learning processes in the classroom, and the level of understanding and awareness of ethnochemistry and the scientific process. This type of research is quantitative descriptive with a comparative approach using an experimental method with a control group. The sample determination was done by random sampling technique taken at one of the Vocational Schools in East Aceh on Food Expertise Program. Data collection is done through evaluating student learning outcomes using multiple choice questions, measuring learning effectiveness and understanding of ethnochemistry using observation sheets and structured interview sheets. The research results obtained student learning outcomes in the experimental class were on average higher than the control class, even though the results of statistical using t test did not show a significant difference. The score of the observation result of learning effectiveness in the experimental class is higher than the control class that is equal to 89,532 with very good criteria. Measurement of students' understanding of ethnochemistry after the application of the module obtained an increase of 40 points compared to before the application of the module. This shows an increase in students' understanding and awareness of ethnochemistry and the scientific process that take place in it and can strengthen the justification that learning modules with ethnochemical approaches are very well applied as teaching material
Analisis Konten Buku Teks Geografi SMA Menggunakan Model Beck & McKeown
Full text linkPenelitian ini bertujuan untuk mengetahui konten (isi) buku teks geografi yang digunakan oleh siswa dan guru Sekolah Menengah Atas di Kota Langsa. Penelitian ini menggunakan metode analisis deskriptif. Analisis isi (konten) menggunakan model pengembangan kognitif Beck & McKeown dengan memodifikasi menjadi enam langkah. Hasil penelitian menunjukkan bahwa sebagian besar buku teks geografi hanya mengandung fakta, data, dan konsep sehingga dapat digolongkan Not close look at problematic discussion. Buku teks yang tidak dapat membantu siswa untuk belajar menyelesaikan masalah dan berfikir kreatif.

PENGEMBANGAN MODUL KOMPOS TERINTEGRASI KONSEP KIMIA SEBAGAI BAHAN AJAR UNTUK SISWA PROGRAM AGRIBISNIS TANAMAN PERKEBUNAN (ATP) SMKN ACEH TIMUR
Full text linkKurikulum pembelajaran di SMK merupakan kurikulum yang menggabungkan mata pelajaran adaptif, normatif dan produktif. Kelompok mata pelajaran tersebut diharapkan agar saling mendukung dan saling melengkapi, namun pada kenyataannya kedua kelompok pelajaran tersebut tidak saling mendukung sehingga terjadi kesenjangan antara pelajaran adaptif dan produktif. Tujuan penelitian ini adalah (1) mengembangkan modul pembelajaran untuk pelajaran produktif (teknik pengomposan) yang mengintegrasikan konsep pelajaran adaptif (kimia), (2) mengumpulkan tanggapan guru dan siswa terhadap modul, (3) penilaian kualitas modul oleh ahli, (4) uji efektivitas modul. Metode penelitian mencakup pengembangan modul kimia kompos dilakukan dengan menggunakan model ADDIE yang terdiri dari analisis kebutuhan modul, perancangan modul, pengembangan modul, implementasi modul dan evaluasi modul. Hasil penelitian menunjukkan bahwa 92% guru dan 85% siswa memberikan respon positif terhadap modul, penilaian ahli untuk kualitas modul menunjukkan skor sebesar 3,36 (baik), dan uji efektivitas modul menunjukkan kriteria sangat baik, hasil ini diukur dari hasil tes belajar siswa dengan perolehan nilai rata-rata total sebesar 87 (sangat baik)
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
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
