Factors influencing the individual investors of Bangladesh to opt for investment in ṣukūk

Purpose – This study aims to identify the factors that influence the willingness of Bangladeshi retail investors to invest in ṣukūk. Design/methodology/approach – The authors surveyed Bangladeshi retail investors using a structured questionnaire to understand their perspectives on potential investment in ṣukūk. The authors considered the behavioral aspects of retail investors and the desired ṣukūk features to analyze the demand side. Factors and regression analyses were performed to identify the persuading factors. Findings – The results indicate that investor awareness is a fundamental factor in potential investments in ṣukūk. Investors perceive the security represented by government and third-party guarantees as a persuasive feature of ṣukūk. The tradability and tenor of ṣukūk also affect the investment intention. Sharīʿah consciousness of the investors also plays a significant role in their investment decisions. Research limitations/implications – One limitation of this study is that it incorporates potential individual investors only, and precludes institutional investors. In the future, there is scope for research to explore the demand factors impacting institutional investors of ṣukūk in Bangladesh. Practical implications – The authors expect that the study will aid policymakers and ṣukūk issuers in crafting strategies to cater to the needs of Bangladeshi retail investors. Originality/value – This study is the earliest research conducted in Bangladesh to determine the factors impacting the willingness of individual investors to make their potential investments in ṣukūk. To the best of the authors' knowledge, no study has analyzed the desired ṣukūk features from the perspective of Bangladeshi retail investors

Pengajaran matematik berasaskan animasi untuk meningkatkan kefahaman pelajar pada topik dimensi 3 di sekolah menengah

The purpose of this study is to identify the problems in teaching and learning and the appropriateness of learning method used in dimensi 3 topics in secondary school mathematics. The learning method used was structured inquiry-based learning model animation courseware. The research design used in this study was divided into two phases: the first phase used a case study design and the second phase used a quasi experimental design (non-equivalent control group design). A total of 124 students Sekolah Menengah Atas (SMA) in Tanjungpinang and Bintan, Kepulauan Riau of Indonesia were samples of this study (62 for the experimental group and 62 for the control group). Data collection was conducted using questionnaires, observation, interviews and mathematics tests (Dimensi 3 topics). The questionnaire was conducted to the experimental group and 6 students were selected for an interviews session after the teaching and learning proses using the animation courseware. Mathematics tests were conducted to both control and experimental groups for comparison. The qualitative data were analyzed using thematic analysis were the quantitative data were analyzed using statistical descriptive and inferential methods. The findings of the first phase indicate that problems existed after the implementation of the teaching and learning of mathematics using conventional method. Among them are the habit in the students' attitudes about learning mathematics; uninteresting teaching approach that bored students; conventional teaching methods, and difficulties in understanding mathematical concepts. T tests were conducted to identify the difference in mean for both experimental and control groups in the second phase. This study showed an increase in the mean of mathematics test in the experimental group (4.36 for SMA A Bintan and 6.29 for SMA B Tanjung Pinang) compared with the control group. The teaching and learning with animation courseware made learning mathematics more appealing and fun. Therefore this effort needs to be implemented in schools to improve the quality of teaching and learning mathematics in the future
