Abstract

Abstract Language learning strategy is one of the main factors that help determine how well our students learn a second or foreign language (Oxford, 2003). Research has shown that more effective language learners use more and better learning strategies than poorer language learners (Rubin, 1975; Stern, 1975). This research investigates the difference in ESL learning strategies used by students with different levels of ESL learner motivation and how gender plays a role in both. Strategy Inventory of Language Learning (SILL; Oxford, 1990) and English Language Learner Motivation Scale (ELLMS; Ardasheva, Tong and Tretter, 2012) were used and adopted to measure English language learning strategies  and English language learner motivation, by employing 65 male students and 75 female students from Budi Utama Junior High School as participants. The data analyzed showed that there was significant difference in ESL learning strategies used by the students with different levels of ESL learner motivation but there is no significant role of gender in ESL learner motivation and ESL learning strategies. Keywords: ESL, gender,  learner motivation,  learning strategy. DOI: doi.org/10.24071/llt.2018.210101

Abstract

Salah satu konsekuensi pergantian kurikulum di jenjang pendidikan dasar dan menengah adalah pergantian buku pelajaran yang akan digunakan oleh para siswa. Hal ini tidak jarang merepotkan perpustakaan sekolah, khususnya dalam menyediakan buku pelajaran sesuai kurikulum terbaru dengan anggaran yang cenderung terbatas. Analisis secara mendalam menunjukkan bahwa materi-materi pelajaran kurikulum terbaru tidak jauh berbeda dengan kurikulum sebelumnya. Penelitian ini bertujuan untuk menyusun tabel pokok bahasan pada beberapa mata pelajaran sesuai Kurikulum 2013 (revisi 2016) jenjang Sekolah Menengah Atas (SMA)/sederajat. Menggunakan tabel tersebut, pustakawan sekolah dapat membantu para pemustaka untuk memanfaatkan buku pelajaran pada kurikulum sebelumnya (Kurikulum 2013/Kurikulum Tingkat Satuan Pendidikan 2006/Kurikulum Berbasis Kompetensi 2004) yang masih tersedia di perpustakaan sekolah.

Abstract

Portfolio is a type of investment consists of several assets, such as stocks. Single index model is a portfolio optimization method that uses the market index value to calculate beta as a measure of asset’s performance. However, there are several market index available in Indonesia Stock Exchange. In this study, we examine and compare the performance of several market index to the portfolio’s performance that calculated using Single-Index Model. We choose several stocks that used in several market index, obtain the return data, and obtain the beta using several market index. The calculation of the optimal portfolio were repeated using 15 sets of data to obtain consistency. Based on the empirical study, we obtain that the way to choose the market index could affect the estimated beta as well as its standard error. However, it has a very small effect on the weight and the performance of the optimal portfolio.

Abstract

Abstrak. Mata uang crypto atau mata uang virtual merupakan salah satu bentuk investasi yang berkembang sejak 2010. Dewasa ini, terdapat lebih dari 2.000 jenis mata uang crypto di seluruh dunia. Riset-riset mata uang crypto di Indonesia masih terfokus pada status kehalalan dan status hukum dari investasi mata uang crypto. Penelitian deskriptif kuantitatif ini bertujuan untuk mendeskripsikan imbal hasil dan risiko investasi mata uang crypto. Analisis secara deskriptif dengan penghitungan ukuran risiko serta penggunaan model heteroskedastik GARCH (1,1) dilakukan pada data return 15 mata uang crypto yang memiliki nilai terbesar. Diperoleh informasi bahwa investasi sebagian besar mata uang crypto menghasilkan keuntungan yang lebih tinggi dibandingkan investasi pada mata uang asing maupun pasar saham. Di sisi lain, mata uang Crypto memiliki risiko kerugian yang lebih tinggi dan sifat volatility clustering atau heteroskedastisitas. Riset lebih lanjut diperlukan untuk mengungkap sifat-sifat return mata uang Crypto dan performanya dalam bentuk portfolio.Kata kunci: Bitcoin, mata uang virtual, rupiah, investor, pasar modal.Abstract. Cryptocurrency or virtual currency is a kind of investment that is common since 2010. Nowadays, there are more than 2.000 cryptocurrencies around the world. Research about cryptocurrency in Indonesia still focused on the legal or religious status of its investment. This descriptive-quantitative research aim is to describe the return and the risk of cryptocurrency investment. Therefore, we use the descriptive analysis and the GARCH (1,1) model to the return data of 15 cryptocurrencies with the largest market value. Most of these cryptocurrencies can yield a higher return when compared with the return of the foreign exchange and stock market return. Despite this benefit, they exhibit higher risks and volatility clustering or heteroscedasticity. Further research should be done to reveal more properties of their return and performance in portfolio.Keywords: Bitcoin, virtual currency, rupiah, investor, stock market.

Abstract

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.

Abstract

Shifting students to a growth mindset can increase their achievements. Nevertheless, only a few studies have been conducted on this topic in developing countries. This study aims to examine the relationship between growth mindset, school context, and mathematics achievement in Indonesia. Using a multilevel model on the PISA 2018 data, this study explored the variables that contributed to mathematics achievement. The multilevel analysis showed that students’ gender, growth mindset, index of economic social, and cultural status were statistically significant predictors of students’ mathematics achievement. Girls have been reported to have a higher mathematics achievement than boys in Indonesia. As the students’ growth mindset increases, so do their mathematics achievement.
