Abstract

Setiap proses pembelajaran memerlukan suatu evaluasi berupa tes. Dalam perkembangannya tes dapat dilakukan secara online. Jenis tes antara lain tes benar salah, test pilihan ganda, tes mencocokan, dan tes esai. Sudah banyak penelitian di luar negeri maupun di dalam negeri yang mengembangkan metode-metode sebagai penilai jawaban esai otomatis. Sebagai contoh Eksperimen LSA untuk esai GMAT (Graduation Management Achievement Test) menghasilkan persetujuan dengan manusia sebesar 85%-91% (Valenti, Neri, & Cucchiarelli, 2003), Electronic Essay Rater (E-Rater) menghasilkan 87%-94% (Valenti, Neri, & Cucchiarelli, 2003), untuk penelitian di dalam negeri hasil uji coba SIMPLE (Ratna, Budiharjo, & Hartanto, 2007) menghasilkan 69.80%-94.64% untuk lima mahasiswa dan 77.18%-98.42% untuk sepuluh mahasiswa. Hasil yang didapatkan masih jauh dari yang diharapkan. Hal ini yang mendasari dilakukannya penelitian mengenai pembobotan yang baik dalam penilaian jawaban esai otomatis. Penelitian ini membandingkan Algoritma pembobotan TF/IDF dan BLEU dengan alat bantu Automatic Essay Scoring yang berbasis web untuk membobotkan jawaban siswa terhadap kunci jawaban esai serta meneliti pengaruh perluasan kunci jawaban serta penyisipan huruf pada kata kurang huruf (toleransi) untuk memaksimalkan hasil penilaian. Algoritma TF-IDF merupakan salah satu skema pembobotan istilah/term dalam pencarian dokumen yang terdiri pembobotan lokal Frequency Term (TF), pembobotan global Inverse Document Frequency (IDF), dan normalisasi. Sedangkan Algoritma BLEU merupakan salah satu sistem evaluasi otomatis yang dikenalkan oleh grup riset IBM. Dalam penelitian ini penulis menghitung nilai BLEU sampai 4-gram (4 kata) saja, sedangkan esai yang dinilai dibatasi pada esai yang merupakan jawaban dari pertanyaan pada tes esai (maksimal 250 kata per jawaban), bukan esai karangan yang panjang (lebih dari 250 kata) dan jawaban yang dinikai berupa kalimat bukan berupa jawaban hasil perhitungan (matematika, fisika dan kimia). Uji coba dilakukan dengan 10 soal esai dengan 22 peserta ujian. Secara keseluruhan, rata-rata korelasi TF/IDF-penilaian guru mencapai 0.70 dengan nilai korelasi tertinggi mencapai 0.98, sedangkan rata-rata korelasi BLEU-penilaian gurur mencapai 0.63 dengan nilai korelasi tertinggi mencapai 0.97. secara keseluruhan nilai yang dihasilkan algoritma TF/IDF lebih tinggi dari BLEU. Every learning process requires an evaluation of a test. In the development of the test can be done online. Types of tests include tests completely false, multiple choice tests, matching tests, and essay tests. There have been many studies abroad and within the country are developing methods as assessor automated essay answers. For example Experimental LSA for GMAT essay (Graduation Management Achievement Test) results in agreement with the human by 85% -91% (Valenti, Neri, & Cucchiarelli, 2003), the Electronic Essay Rater (E-Rater) resulted in 87% -94% (Valenti , Neri, & Cucchiarelli, 2003), for research on domestic trial results SIMPLE (Ratna, Budiharjo, & Hartanto, 2007) resulted in 69.80% -94.64% for the five students and 77.18% -98.42% for ten students. The results obtained are still far from the expected. It is for conducting research on a good weighting in the assessment of automated essay answers. This study compared the weighting algorithm TF / IDF and BLEU with Automatic Essay Scoring tools are web-based to membobotkan answers to the answer key student essay and examines the impact of the expansion of the answer key and the insertion of letters in the word less letters (tolerance) to maximize the results of the assessment. Algorithm TF-IDF weighting scheme is one term / terms in the search for documents consisting of local weighting Term Frequency (TF), Inverse Document Frequency weighting globally (IDF), and normalization. While the algorithm is one of the BLEU automatic evaluation system introduced by IBM research group. In this study the authors calculate the value to 4-gram BLEU (4 words) only, while the assessed essay essay is limited to the answers of the questions on the test essay (maximum of 250 words per answer), not an essay written by a long (more than 250 words ) and answer dinikai not be the answer in the form of sentence calculation results (mathematics, physics and chemistry). The test is done with 10 essays by 22 examinees. Overall, the average correlation of TF / IDF-teacher ratings reached 0.70 with the highest correlation value reaches 0.98, while the average correlation of BLEU-assessment gurur reached 0.63 with the highest correlation value reaches 0.97. overall value of the resulting algorithm TF / IDF higher than BLEU.

Abstract

This research is motivated because the learning of ICT is still using the lecture method that is one direction and, teachers are one - the only source of information for students. So that students become passive and less active learning outcomes achieved less than the maximum. One effort to overcome this problem is by using Snowball Throwing learning model that aims to determine the activity and student learning outcomes.This study design using quasi-experimental design to study design pretest-posttest control group design. The samples in this study using cluster random sampling technique. And obtained VIID grade students as an experimental class and class VIIA as the control class. Techniques used in data collection that documentation, observation and tests.The results showed that the average activeness in class experiments of 80.07% with both categories. While the value - average learning outcomes of students in the experimental class increased to 83.03 to test the gain obtained at 0.558%. The conclusion that Snowball Throwing learning model can enhance the activity and student learning outcomes. It is advisable for most teachers use these models on the subjects that diampunya so that the desired learning outcomes achieved.

Abstract

English is an international language that is needed in the development of global information technology. Each persons English skills can be measured by a test called TOEFL. TOEFL (Test of English as a Foreign Language) is a test oriented to American English. The English test used in the eucation world is the TOEFL ITP (Institutional Testing Program) because it focuses on a particular institution. Currently, there are many universities that use TOEFL ITP as one of the requirements of graduation that is adjusted to the standards of each university. Currently many agencies provide services to study and practice TOEFL at a cost that is quite expensive. In this study made alternative implementation of TOEFL simulation to learn, practice and perform TOEFL simulation through android smartphone. The results showed the validation and validation category of the media, the TOEFL ITP simulation application included in the category very well. The effectiveness test obtained Sig. (2-tailed) less than 0.05 ie 0.012 and 0.002 with average Sig. (2-tailed) is 0.007. Test results of 82.5% outcome result results with very good category. So it can be concluded that the application called TOEFL OS enthused by the user and has been appropriate user needs as an alternative learning media TOEFL.
