In the last decade, micro-lectures have been widely used to teach mathematics, but only a few studies have examined the factors affecting teachers’ intentions of using micro-lectures. As teachers are key to integrating modern technologies such as micro-lectures into students’ learning processes, knowledge about teachers’ intentions in this regard could be of particular importance. This study aimed to analyze the behavioral intention (BI) of mathematics teachers in using micro-lectures in mathematics in China, and identify the most influential factors involved, for the very first time. The Unified Theory of Acceptance and Use of Technology (UTAUT) model was used as a design model to investigate teachers’ BIs concerning the use of micro-lectures, and we used an online questionnaire to collect quantitative data. The participants in our research were 174 mathematics teachers from China, 166 of whom provided us with evaluable questionnaire data. Furthermore, partial least squares (PLS) regression was used, and hypothesis testing was performed with the Smart-PLS software. From the results, BI was positively affected by Performance Expectancy (PE), Effort Expectancy (EE), and Social Influence (SI). BI and facility conditions also had positive effects on user behavior; in contrast to other studies, SI had the most significant positive effect on BIs in our study. Our findings could provide insights into both future strategies for successful technology integration in mathematics classes and into mathematics teachers’ intentions towards integrating technologies into mathematics teaching.
This study aims to describe the effectiveness of the Assessment for Learning (AfL) in improving the quality of learning and mathematics learning outcomes in elementary schools. This study used a quasi-experimental method with a non-equivalent control group design. The instrument used was a test instrument with good validity, reliability, difficulty level, and different power. The non-test instrument was valid and good. Data analysis was performed using descriptive statistics, mean difference test, and variance difference test on AfL learning outcomes. The results showed that the effectiveness of learning in implementing AfL could be influenced by assessment preparation, student involvement, and follow-up assessment. The quantitative analysis results show that AfL can improve student learning outcomes; there is no mean-variance in AfL learning outcomes; There are differences in learning outcomes, and there are no variants in learning with AfL and conventional assessments. Suggestions, it is necessary to plan the assessment process, diagnose student needs and abilities. Moreover, there is a need for follow-up and feedback to see achievements
The National Examination in Indonesia, which began in 2015, was no longer a determinant of student graduation at the end of the education level. Utilization of the examination results will affect the seriousness of the students in working on it. This study aims to describe the level of seriousness of 12th grade students in working on National Examinations, when it no longer a determinant of graduation by examining teachers and school principals’ point of view. This research is a qualitative study by using the phenomenology approach. Data was collected using focus group discussions (FGD) conducted 3 times in 3 provinces in Indonesia, consisted of Yogyakarta, South Kalimantan and East Nusa Tenggara. FGD participants were 9 high school principals, 9 vice principal of curriculum, and 54 teachers who teach subjects that are tested on national exam. In each province, three schools were selected, consisted of two public schools, and one private school. Data were analyzed using data reduction stages, to find relationships between themes, and verification. The results showed that the motivation of 12th grade students in preparing National Examination were reduced. They no longer focused on preparing the exams, otherwise they preparing themselves for higher education. Furthermore, students tended to select subjects that were easier and the teacher should motivate students harder to prepare for the National Examination.
Tujuan penelitian yaitu mengeksplorasi tantangan dan kesiapan guru dalam melaksanakan pembelajaran matematika secara daring dilihat dari dimensi-dimensi pedagogik dan melihat upaya guru dalam mengembangkan pembelajaran matematika secara daring. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi eksplorasi. Teknik sampling yang digunakan yaitu purposive sampling. Subjek penelitian yaitu orang tua/wali siswa dan guru yang melaksanakan pembelajaran matematika secara daring. Pengumpulan data menggunakan kuesioner dan wawancara. Instrumen yang digunakan sudah divalidasi oleh ahli dan nilai validasi yaitu 0,803 yang mengindikasikan sangat valid. Analisis data menggunakan statistik deskriptif dan analisis model Bogdan & Biklen. Hasil temuan menunjukkan bahwa tantangan dalam pembelajaran matematika secara daring yaitu peningkatan literasi digital, fasilitas belajar, pengembangan karakter, dan evaluasi pembelajaran. Namun yang menjadi sorotan yaitu literasi digital. Hal ini menjadi faktor yang sangat penting dalam menjawab tantangan pada pembelajaran secara daring. Melihat hal tersebut, guru belum cukup siap dalam melaksanakan pembelajaran secara daring. Kemudian, upaya-upaya yang bisa dilakukan oleh guru dalam meningkatkan pembelajaran matematika berbasis daring yaitu pada segi pemahaman, guru perlu meningkatkan literasi teknologi, inovasi perencanaan pembelajaran dan perkembangan belajar. Sementara pada segi pelaksanaan guru perlu meningkatkan komunikasi, bimbingan, pendekatan menggunakan media teknologi dan kerjasama dengan orangtua pada proses pembelajaran.
Dalam melakukan standarisasi pendidikan di Indonesia maka dilakukan Ujian Sekolah Berstandar Nasional (USBN).Karena perangkat tes yang digunakan dalam USBN tersebut sebagian besar butir tesnya dikembangkan oleh guru, perangkat tes yang diujikan kepada siswa di daerah yang satu akan berbeda dengan daerah yang lainnya meskipun sama-sama mengacu pada kisi-kisi dari pemerintah. Oleh karena itu perlu dilakukan penyetaraan perangkat tersebut. Penelitian deskriptif eksploratif dengan pendekatan kuantitif ini bertujuan untuk mendeskripsikan kesetaraan perangkat USBN tahun 2018/2019 pada mata pelajaran matematika wajib. Pengumpulan data dilakukan melalui dokumentasi respon siswa pada USBN 2018/2019 untuk mata pelajaran matematika wajib. Respon siswa tersebut berasal dari lima paket soal dari empat sekolah menengah atas di Provinsi D.I. Yogyakarta dan Kalimantan Selatan. Data yang terkumpul dianalisis menggunakan teknik equating berdasarkan teori respon butir dengan metode mean-mean, mean-sigma, Haebara, dan Stocking Lord. Estimasi parameter butir dan equating dilakukan dengan bantuan program R. Hasil penyetaraan menggunakan empat metode menunjukkan bahwa lima paket tes USBN 2018/2019 untuk mata pelajaran matematika wajib cenderung setara satu sama lain dan penyetaraan menggunakan metode Haebara menghasilkan kesetaraan yang lebih baik dibandingkan dengan tiga metode equating lainnya. Dalam artikel ini juga disajikan contoh butir sulit beserta peluangnya untuk digunakan sebagai referensi dalam meningkatkan kualitas pembelajaran matematika. How are the results of the equating of test packages of mathematics USBN with item response theory?AbstractIn standardizing education in Indonesia, then Ujian Sekolah Berstandar Nasional (USBN) or National-Standardized School Examination was conducted. Because most of the test items contained in the test packages which were used in USBN were developed by the teachers, the test packages which were administered to students in a region would be different from other regions. Therefore, there was a need to do equating towards those test packages. This exploratory descriptive research with a quantitative approach was focused on describing the equality of test packages of USBN year 2018/2019 for compulsory mathematics subject. Data collection was done through documentation of students’ responses to the USBN 2018/2019 for compulsory mathematics subject. These students’ responses were collected from five test packages from four senior high schools in Province of Special Region of Yogyakarta and South Kalimantan, Indonesia. The collected data were analyzed by using an equating technique based on the item response theory with the methods of mean-mean, mean-sigma, Haebara, and Stocking Lord. The item parameter estimation and equating were conducted with the aid of the R program. The results of equating showed that the five test packages of the USBN 2018/2019 for compulsory mathematics subject tend to be equal to each other and the equating through Haebara method yields better equality than the other three equating methods. This article also presents the example of a difficult item as well as its opportunity to be used as a reference for enhancing the quality of mathematics learning.
