Model Computerized Adaptive Test (CAT) untuk Ujian Pendidikan Kesetaraan
No full textStudi ini bertujuan untuk: (1) mengembangkan bank soal terkalibrasi dan model Computerized Adaptive Test (CAT) untuk sistem ujian akhir, khususnya peserta didik program Paket C setara SMA, dan (2) untuk mengevaluasi tingkat efektifitas dan akurasi CAT dalam mengukur kemampuan peserta tes. Di samping bank soal dan model CAT, studi ini juga menghasilkan program aplikasi untuk pengelolaan bank soal dan Computer Based Test (CBT).
Studi ini merupakan penelitian dan pengembangan (research and development, R&D) yang mencakup 8 (delapan) langkah kegiatan, yaitu: identifikasi kebutuhan, pengembangan produk awal, evaluasi dan pengujian internal, penyempurnaan produk tahap pertama, ujicoba skala terbatas, penyempurnaan produk tahap kedua, ujicoba skala lebih luas, dan finalisasi produk. Analisis dan kalibrasi terhadap 233 butir soal dilakukan untuk mendukung bank soal. Validasi terhadap bank soal dilakukan oleh 6 (enam) orang ahli materi. Diskusi kelompok (focus group discussion) yang melibatkan 5 (lima) orang pakar di bidang psikometri dan teknologi komputer diselenggarakan dalam rangka evaluasi dan validasi program aplikasi (bank soal, CBT, dan CAT). Ujicoba CAT dengan skala terbatas melibatkan 28 orang sukarelawan, sedangkan ujicoba skala lebih luas melibatkan 88 siswa dari 3 sekolah, yaitu SMA Kolombo, SMA Negeri 1 Kasihan, dan SMA Negeri 2 Metro. Dari hasil ujicoba skala lebih luas, diperoleh rata-rata panjang tes pada CAT masing-masing adalah (21,67 + 4,67 SD); (20,62 + 3,63 SD), dan (17,37 + 4,18 SD). Rata-rata kesalahan baku pengukuran (standard error of measurement, SEM) masing-masing adalah 0,3342; 0,3238, dan, 0,3293.
Kesimpulan dari studi ini adalah (1) bank soal dan CAT yang dikembangkan siap untuk dijadikan sebagai prototipe dalam pengembangan selanjutnya, baik untuk mata pelajaran lain atau untuk jenis dan jenjang pendidikan lain, dan (2) hasil pengukuran oleh CAT lebih efektif dibandingkan dengan tes konvensional dengan tingkat akurasi pengukuran yang setara dengan reliabilitas 0,90 pada teori tes klasik. Sebagai tambahan, CAT yang dikembangkan memperoleh nilai baik berdasarkan expert judgement dan berdasarkan persepsi subjek coba. Namun demikian, studi ini masih memiliki beberapa kelemahan dan keterbatasan, seperti proses equating bank soal yang belum sempurna karena tidak tersedianya anchor items, ukuran bank soal yang belum memadai, serta banyaknya subjek coba yang masih terbatas. Rekomendasi untuk studi selanjutnya antara lain perlu dilakukan rekalibrasi terhadap karakteristik butir soal dalam bank soal, dilakukan ujicoba pada sampel yang lebih luas, serta adanya penelitian di beberapa aspek seperti kendali eksposur butir, kendala waktu dan konten, serta sistem keamanan
Validitas dan Reliabilitas SCARED Berbahasa Indonesia Menggunakan Model Rasch
Full text linkGangguan kecemasan pada anak dan remaja Indonesia memerlukan instrumen diagnostik yang valid dalam Bahasa Indonesia, namun ketersediaannya masih terbatas. Penelitian ini menganalisis validitas dan reliabilitas instrumen SCARED (Screening for Children Anxiety Related Emotional Disorders) versi Bahasa Indonesia menggunakan model Rasch. Adaptasi instrumen dilakukan melalui forward-backward translation, review ahli, dan pilot study pada 51 siswa SMP. Hasil menunjukkan properti psikometrik yang baik dengan reliabilitas person 0,91 dan reliabilitas item 0,94. Separation index sebesar 3,14 (person) dan 4,00 (item) mengonfirmasi kemampuan instrumen membedakan responden dan item secara signifikan. Analisis fungsi informasi tes membuktikan instrumen sangat efektif (precision >0,80) dalam mengukur kecemasan pada rentang -2,0 hingga +2,0 logit. Nilai Real RMSE rendah (0,29 untuk person; 0,26 untuk item) mengindikasikan presisi pengukuran tinggi. Penelitian ini mengisi kesenjangan penting dengan menyediakan instrumen skrining kecemasan tervalidasi empiris untuk populasi anak dan remaja Indonesia, berkontribusi pada upaya deteksi dini dan penanganan gangguan kecemasan dalam konteks klinis dan pendidikan
Indonesia National Curriculum Reform in the Context of Standard-Based Education: Policy and Implementation
No full textAbstract
Curriculum reform plays an essential role in assuring the success of systematic educational change. The purpose of this study is to portray the government policy and the issues of the Curriculum 2013 implementation. This study employed qualitative methodology using document analysis, observation and Focused Group Discussion (FGD) as data collection techniques. The results of this study show that the curricula philosophy of curriculum reform was well-articulated and relevant to meet the requirements of twenty-first century learning competencies. However, the curricula implementation process faced substantial challenges with technical problems regarding the national standards of education document, teacher training and competences, the availability of school textbooks, and classroom assessment implementation. The findings of this study have several implications for implementing the national curriculum in Indonesia. Therefore, alignment between the national standards of education document, the curriculum structure, and the assessment system is required in order to ensure the successful implementation of Curriculum 2013 throughout the nation.

Reformasi kurikulum memainkan peran penting dalam memastikan keberhasilan perubahan pendidikan yang sistematis. Tujuan dari penelitian ini adalah untuk menggambarkan kebijakan pemerintah dan isu-isu implementasi Kurikulum 2013. Penelitian ini menggunakan metodologi kualitatif menggunakan analisis dokumen, observasi dan diskusi kelompok terpumpun sebagai teknik pengumpulan data. Hasil penelitian ini menunjukkan bahwa filosofi reformasi kurikulum diartikulasikan dengan baik dan relevan untuk memenuhi persyaratan kompetensi pembelajaran abad kedua puluh satu. Namun, proses implementasi kurikulum menghadapi tantangan besar dengan masalah teknis mengenai dokumen yang terkait dengan standar nasional pendidikan, pelatihan dan kompetensi guru, ketersediaan buku pelajaran di sekolah, dan implementasi penilaian di dalam kelas. Temuan penelitian ini memiliki beberapa implikasi untuk menerapkan kurikulum nasional di Indonesia. Oleh karena itu, diperlukan keselarasan antara dokumen standar nasional pendidikan, struktur kurikulum, dan sistem penilaian untuk memastikan keberhasilan implementasi Kurikulum 2013 di seluruh negara
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
