Colligative Properties

Students often have difficulty in understanding chemistry lessons, especially Colligative Properties. Teachers should have systematic learning plans so that students understand the content of learning well. Hypothetical Learning Trajectory (HLT) is effective to be used in the learning process because it becomes an idea in designing detailed learning paths. Besides that, learning outcomes can be achieved well and optimally. This study uses qualitative and quantitative approaches. Data processing is carried out based on four assessment criteria. First, student responses that appear based on response predictions, second, student ability test scores, third, analysis of learning activities, and finally science process skills (SPS). The results showed that the didactic presented by the teacher as a student learning path was good enough. Only 12% of student responses are beyond predictions. Furthermore, student SPS through the use of HLT shows that classification and communication skills have a high value, respectively 82% and 81%. Meanwhile, based on Piaget's approach, students' conceptual abilities are better (56%), compared to other abilities. Therefore, the application of HLT to the material of colligative properties towards students is very good.

Important Activity

Pembuktian dalam matematika adalah suatu aktivitas yang penting, tetapi aktivitas ini tergolong sulit bagi mahasiswa calon guru matematika. Masalah ini salah satunya dipengaruhi oleh kepercayaan-diri. Tujuan penelitian ini adalah untuk menganalisis karakteristik pencapaian kemampuan pembuktian matematis dan kepercayaan-diri mahasiswa melalui metode Moore. Penelitian ini menggunakan metode campuran bertahap yaitu tahap kuantitatif dan tahap kualitatif. Pada tahap kuantitatif disimpulkan bahwa kemampuan pembuktian pada kelas yang menggunakan metode Moore lebih baik daripada kelas yang menggunakan model pembelajaran langsung. Metode Moore dapat mengungkap proses perkembangan capaian pembelajaran mahasiswa dalam pembuktian, sehingga dosen dapat memberikan umpan balik untuk mengembangkannya. Pada tahap kualitatif, dihasilkan karakteristik kemampuan pembuktian beberapa mahasiswa. Karakteristik ini ditinjau berdasarkan respon mahasiswa terhadap masalah pembuktian. Pada pembelajaran dengan metode Moore, mahasiswa tidak diperbolehkan membuka bahan ajar, sehingga dosen harus mengikuti alur berpikir mahasiswa dan mengarahkan proses berpikirnya. Sebagai implikasi, metode Moore baik digunakan dengan catatan mahasiswa harus belajar terlebih dahulu sebelum pembelajaran di kelas.Proving in mathematics is an important activity, but this activity is classified as difficult for prospective mathematics teacher students. This problem is influenced by self-confidence. The purpose of this study was to analyze the characteristics of achievement of students' mathematical proving ability and self-confidence  through the Moore method. This study uses a phased mixed method, namely quantitative and qualitative stages. In the quantitative stage, it was produced: "Based on the overall and PAM categories, the ability to prove the class using the Moore method is better than the class that uses the direct learning model". Moore's method can reveal the process of developing student learning outcomes in proof, so that lecturers can provide feedback to develop it. In the qualitative stage, the characteristics of the ability of several students are produced. these characteristics are reviewed based on student responses to the problem of proof. In the Moore method of learning, students are not allowed to open teaching materials, so the lecturer must follow the flow of student thinking and direct the thinking process. As an implication of the results of this study, the Moore method is well used with the notes that students must study before learning in class.

Courses Intermediate and Advanced Finance, Economics, Islamic Economics & Finance, Islamic Banking & Finance, Islamic Capital Market and other relevant courses. Specifictopics/syllabus Capital markets instruments, conventional or Islamic. Case overview This case focuses on Tracoma Holding Berhad Bai Bithaman Ajil Debt Securities (BaIDS) amounting to RM 100 million which was issued by Tracoma Holding Berhad in 2005. It was the first issuance of a sukuk (Islamic debt securities or bond) by the company. The proceeds were used to finance its growth and to repay existing bank borrowings and capital requirements. This case is interesting, as it allows students to study the bai bithaman ajil sukuk structure and issuance process in the Malaysian capital market. It also provides basic financial transaction and credit rating of sukuk which requires analytical skills. Being a debt-based facility, the sukuk was subjected to credit rating evaluation by the MARC, the rating agency appointed by the company. Further downgrading of the sukuk meant it would lead to the worst-case scenario. Some actions needed to be taken to solve this issue; therefore, the CFO suggested an urgent meeting with the sukuk holders. Expected learning outcomes The students should be able to: understand the issuance process and the principle of BBA (bai bithamin ajil) in sukuk structure; understand reason(s) methods of fund raising by firm and the allocations of fund; understand the sukuk default issue; analyze the reasons for sukuk default; understand the importance of debt securities credit ratings; and identify investors' protection in the case of sukuk default.
