Abstract

Abstract This study is trying to optimize the effectiveness of English lecturers held  in the non-English departments conducted by lecturers from the English Department of the Faculty of languages and Art (FBS) of the State University of Yogyakarta (UNY). To achieve the objective, this study sets the methods as: 1) selecting core material,2) developing activities in the lecturing, 3) training the candidate lecturers 4) implementing the designed instruction, 5)evaluating and discussing the results of the implementation of the instruction in the target classes. The learning processes run well in the seven target classes, but it runs so slowly in one target class because on belief conflict in the lecturer’s side. Positive aspects reported are: 1) the teaching  method is practical, 2) easy to follow, 3) giving new experience and spirit to students; 4) continually given homework are promoting strong students’ motivation and spirit to study harder, 5) the exercises are helping students to have better understanding and competence of English; teaching materials, methods, and techniques are very effective; the teaching learning processes are felt very special, new, enjoyable, and promoting students’ competencies of English. Negative aspects reported are materials to learn are too much comparing to time available, too much of memorization, using uncommon terms, too much time used for  discussing formulas, too much  demanding of command on teaching materials and methods to the teachers, too many numbers of formative tests, short of rich examples for each type of sentences, lack intention of promoting oral communication. Keywords: lecturing of English, basic general subject, the non-English department, learning instruction design.

Abstract

Penelitian ini bertujuan untuk menganalisis kualitas butir soal Penilaian Tengah Semester (PTS) mata pelajaran matematika SMAN 1 Kota Mungkid. Penelitian ini merupakan penelitian deskriptif kuantitatif. Subjek penelitian ini adalah siswa kelas XI MIPA 4 dengan instrumen tes berupa soal pilihan ganda. Butir soal dianalisis berdasarkan teori klasik yaitu indeks kesukaran, daya pembeda, reliabilitas, dan efektivitas pengecoh. Hasil analisis indeks kesukaran terdapat 3 soal kategori sukar, 12 soal kategori sedang, dan 5 soal kategori mudah. Daya pembeda soal menunjukkan 16 soal kategori sangat baik, 1 soal kategori cukup baik, 2 soal kategori sedang, dan 1 soal kategori buruk. Analisis reliabilitas menunjukkan soal memenuhi kriteria reliabilitas dengan kategori baik. Efektivitas pengecoh pada soal menunjukkan 3 soal kategori sangat baik, 6 soal kategori baik, 8 soal kategori kurang baik, 2 soal kategori tidak baik, dan 1 soal kategori sangat tidak baik. Secara keseluruhan terdapat 8 butir soal memenuhi kriteria soal sangat baik dan dapat digunakan kembali.

Abstract

In the 21st century, education focused on equipping students with abilities for lifelong learning and self-development, one of which was problem-solving ability. This ability was crucial in preparing students to solve real-life problems. The SAVI (Somatic, Auditory, Visual, Intellectual) learning model was one of the instructional models that could enhance students' mathematical problem-solving ability and could be integrated with technology use. This study aimed to examine the effect of the SAVI learning model assisted by multimedia on students' mathematical problem-solving ability. This research was a quasi-experimental study using the non-equivalent posttest only control group design. The sample consisted of classes X-1 and X-2 from a public high school in Magelang. The sample was selected by random sampling technique. The data obtained were processed using Independent Sample t–test and effect size. The results of the data analysis showed that there was a significant difference in students' mathematical problem-solving ability between the control and experimental groups. In addition, an effect size of 0.7 was obtained, indicating that the SAVI learning model assisted by multimedia had a large impact on mathematical problem-solving ability. This study recommended broader implementation and exploration in other subjects to enhance learning effectiveness.
