Education is a key to a successful life for all human beings. Having a good education certainly helps people to have a better life and improve their living standard. Therefore, education should be continually conducted meaningfully to enhance students’ competence. However, carrying out effective learning and appropriate classroom assessment during the coronavirus pandemic could be highly challenging for the teachers to do. Teachers need to utilize various technological devices to assess students' learning competence. This is due to online learning has become a priority in learning activities in the pandemic situation. Consequently, teachers must have broader horizons on how to conduct the learning processes and appropriate assessment strategies and operate various communication technologies. This study found that English teachers implemented three types of online assessment strategies to improve students' learning competence during the pandemic of Covid-19 in Indonesia. Those strategies are online test administration, portfolio, and self-assessment. Several challenges were accoutered by the teachers in carrying out the classroom assessment through online systems such as slow internet network, expensive internet quota prices, limited access to computer and smartphone devices, poor ability in using digital technology, difficulty in conducting effective interaction. Feedback was occasionally provided when the learning processes were conducted through zoom meeting or google meet. The study implies that teachers should improve their communication technology ability and fulfill online assessment strategies' administrative procedures.

This study adopted a pretest-posttest nonrandomized control group design in a quasi-experimental setting. The population comprised all students grade XI IPA of SMA Negeri 1 Jetis D. I. Yogyakarta in the second semester of the academic year 2012/2013 consisting of three classes. Two classes were selected as the research sample, namely experimental class and control class. The instruments of the study were a test of MCA and scale of self-efficacy. The data were analized using the one sample t test and MANOVA test. The findings of the study show that the instruction using BBLA has an effect on students’ mathematical communication ability and self-efficacy.Keywords: Brain-Based Learning Approach (BBLA), mathematical communication ability, self-efficacy

Statistical literacy, which is the ability to use statistics in daily life, is an essential skill for facing society 5.0. This study aims to explore first-year university students’ ability to properly use simple descriptive statistics and data visualization. Qualitative data were collected using a set of questions from 39 undergraduate students. Many students were able to calculate various descriptive statistics, but some of them were still unable to determine suitable statistics to describe the data clearly. Related to data visualization, many students failed to provide a meaningful chart that effectively shows the difference between two groups of data. Students with higher statistical literacy tend to use comparison or variability reasoning to determine the usage of descriptive statistics, and use data-based reason in visualizing the data. Improvement in statistical teaching – both in the university and the secondary school – is needed so that the students can use descriptive statistics and data visualization correctly.

Penelitian ini bertujuan untuk menjelaskan pengaruh Mathematics self-efficacy (MSE) terhadap hasil UN Matematika siswa tahun 2015. Penelitian ini merupakan penelitian ex-postfacto dengan desain kausal komparatif yang melibatkan 1 grup eksperimen dan 1 grup kontrol. Total sampel adalah 110 siswa, yaitu 55 siswa jurusan IPA dan 55 siswa jurusan IPS. Instrumen yang digunakan dalam penelitian ini adalah skala MSE. Data penelitian dianalisis menggunakan regresi sederhana dan Analysis of Covariance (ANCOVA). Hasil penelitian ini menunjukkan besarnya pengaruh MSE terhadap hasil UN Matematika adalah sebesar untuk jurusan IPA. Sedangkan untuk jurusan IPS, besarnya pengaruh MSE terhadap hasil UN Matematika adalah sebesar. Hasil pengujian lebih lanjut, ANCOVA, menunjukkan terdapat perbedaan hasil UN Matematika siswa antar kategori MSE dengan melakukan kontrol terhadap hasil TO UN Matematika. Dengan kata lain, dapat disimpulkan bahwa Mathematics self-efficacy (MSE) berpengaruh terhadap hasil UN Matematika siswa tahun 2015.

Tujuan penelitian ini adalah mendeskripsikan kemampuan pemecahan masalah geometri berbasis budaya pada mahasiswa pendidikan matematika ditinjau dari perbedaan gender dan gaya belajar David Kolb. Jenis penelitian ini adalah deskriptif kualitatif dengan subjek penelitian mahasiswa Program Studi Pendidikan Matematika Universitas Tidar pada mata kuliah Geometri Ruang sebanyak delapan mahasiswa (gaya belajar diverging, assimilating, converging, dan accommodating) yang masing-masing gaya belajar terdiri dari laki-laki dan perempuan. Instrumen dalam penelitian ini adalah angket tes gaya belajar David Kolb, soal tes kemampuan pemecahan masalah geometri berbasis budaya dan pedoman wawancara. Data dianalisis secara kualitatif kemudian dibandingkan hasil tes tertulis dan wawancara. Hasil penelitian menunjukkan bahwa mahasiswa dengan gaya belajar diverging, subjek laki-laki berada pada kategori kurang dan subjek perempuan berada pada kategori cukup dalam pemecahan masalah. Kemampuan mahasiswa dengan gaya belajar assimilating, baik subjek laki-laki maupun perempuan berada pada kategori cukup dalam pemecahan masalah. Kemampuan mahasiswa dengan gaya belajar converging, baik subjek laki-laki maupun perempuan berada pada kategori cukup dalam pemecahan masalah. Kemampuan mahasiswa dengan gaya belajar accommodating, baik subjek laki-laki maupun perempuan berada pada kategori cukup dalam pemecahan masalah. Kata kunci: Budaya; gaya belajar; gender; geometri; pemecahan masalah.

The results of the PISA (Program for International Student Assessment) survey in 2012-2015 on the achievement of mathematical competencies of Indonesian students showed a significant increase, but the overall achievement was still below the average of the countries belonging to the Organization for Economic Co-operation and Development (OECD). Furthermore, the results of the Trends in International Mathematics and Science Study (TIMSS) report showed that many students like and feel good about mathematics, but their confidence in their mathematical abilities was quite low. Many studies reveal the close association of Mathematics Self-Efficacy (MSE) with the performance/achievement of students' mathematical competencies. In 2015, the PISA survey was done using computerization except in 15 countries, one of them was in Indonesia. Therefore, the results of this study are to produce the first computer-based MSE scale developed in Indonesia.

Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran berupa lembar kerja siswa (LKS) dengan pendekatan kontekstual untuk meningkatkan kemampuan pemecahan masalah matematika pada materi kubus dan balok, dan untuk mengetahui kualitas perangkat pembelajaran LKS berdasarkan pada aspek kevalidan, kepraktisan, dan keefektifan.

<p>This study aims to analyze the local potential of Gunung Kidul in developing environmentally friendly child-friendly learning models in learning biology. This research was conducted in Gunung Kidul Regency. The population of this research is all local potential in Gunung Kidul Regency. The sample of this study were high school biology teachers, students' parents, and people with disabilities in Gunung Kidul Regency. Surveys and interviews are carried out through observation as well as some clear information on a study of local potential, biology teachers' perceptions of inclusion, and disability. The data obtained are the local potential in Gunung Kidul and teachers' perceptions about inclusion and persons with disabilities. The results of identification of local potentials owned, namely; Pindul caves, Oya river, Oyot caves, and house buildings which are planted with Tectona grandis and Melaleuca leucadendron trees. The results of interviews with teachers, students' parents, and people with disabilities in Gunung Kidul, so far, learning biology is not yet child-friendly. It has not used the environment as a learning resource. This research concludes that it is necessary to develop an environmentally friendly child-friendly learning model in biology learning.</p><p>Keywords: Local potential, Child-friendly learning, environment, and biology learning</p>
