Implementasi teknologi informasi khususnya dalam ujian berbasis komputer (CAT-Computer Assisted Test) mulai banyak digunakan. Kerahasiaan soal yang tersimpan dalam bentuk database menjadi hal utama yang harus diperhatikan, dikarenakan soal yang dipergunakan dalam ujian tidak boleh terpublikasikan (bocor) baik dari sisi peserta test (client) yang menggunakan cat tersebut maupun dari pengelola database (administrator). Dalam paper ini akan dipaparkan salah satu alternative solusi pengamanan soal yang tersimpan dalam bentuk blob-field database yang memuat konten teks maupun konten citra yang disandikan, sehingga konten soal yang aslinya hanya akan terbaca apabila menggunakan aplikasi cat yang sesungguhnya. Teknis penyandian yang dipergunakan dalam blob-field adalah dengan memanfaatkan enkripsi simetrik yang dimunculkan dalam bentuk aplikasi entry bank soal sebagai alat bantu memasukkan soal sekaligus berfungsiuntuk enkripsi konten soal, disisi lain menggunakan aplikasi CAT yang dipergunakan oleh user untukmengerjakan soal sekaligus berfungsi sebagai dekripsi konten soal. Pembuktian hasil enkripsi soal ditunjukkan dengan akses langsung ke dalam blob-field konten soal yang tersimpan pada database menggunakan antarmuka akses database.

AbstractCassava is a strategic crop, especially for developing countries. However, the presence of cyanogenic compounds in cassava products limits the proper nutrients utilization. Due to the poor availability of structure discovery and elucidation in the Protein Data Bank is limiting the full understanding of the enzyme, how to inhibit it and applications in different fields. There is a need to solve the three-dimensional structure (3-D) of linamarase from cassava. The structural elucidation will allow the development of a competitive inhibitor and various industrial applications of the enzyme. The goal of this review is to summarize and present the available 3-D modeling structure of linamarase enzyme using different computational strategies. This approach could help in determining the structure of linamarase and later guide the structure elucidation in silico and experimentally.

This chapter aims to address assessment in the modern age in terms of its importance, challenges and solutions by examining the views of 1,423 users at UK test centres following their recent experience of using two systems which employ computer-based assessment (CBA) and computer-assisted assessment (CAA). Generally speaking, based on the research, which informs the findings presented in this chapter, both systems face similar challenges but there are challenges which are specific to the CAA system. Similarly, both systems may require common solutions to improve user's future experience, but there are solutions which are more relevant to the CAA system. The chapter concludes with a discussion around the UK apprenticeship and a case study of a pilot apprenticeship programme in which CBA and CAA are also integrated.

Assisted Instruction

Students with intellectual and developmental disabilities (IDD) require intensive supports, including those that target behavior, to make progress on literacy goals. In this study, we investigated whether computer-assisted instruction (CAI) may be one effective method to decrease challenging behavior and increase academic engagement. Participants were three students with IDD (7 to 9 years old) who engaged in challenging behaviors during instruction. We used a single-case alternating treatments design to compare levels of challenging behavior and academic engagement during paper-based and CAI (i.e., tablet computer-based) literacy instruction. Results indicated that CAI was associated with decreased challenging behavior and increased academic engagement for two of three participants. In addition, the CAI condition corresponded with higher scores on academic performance assessments for one participant. Although teacher and student measures of social validity were positive, there was limited evidence that results maintained. These findings are described in relation to their limitations, future directions for research, and impact on practitioners.

The number of educational institutions seeking solutions to the problems associated with the burden of expanded student numbers is increasing every day. Most solutions to the problems of delivering course content, supporting student learning, and assessment may be found through the use of computers, thanks to the continuous advances of information technology. According to Bull (1999), using computers to perform assessment is more contentious than using them both to deliver content and to support student learning. In many papers, the terms Computer Assisted Assessment (CAA) and Computer Based Assessment (CBA) are often used interchangeably and somewhat inconsistently. The former usually covers all use of computers in assessment, including reporting and marking, such as in optical mark reading. The latter is often restricted to the use of computers for the entire process, including delivery of the assessment and provision of feedback (Charman and Elmes, 1998). In this paper we will adopt the term Computer Based Assessment and we will discuss some issues related to the online assessment of students.

In a previous paper, we highlighted the design requirements of a computer-based system for the automated assessment of neuropsychological drawing tasks. In this paper, we shall examine the implementation of an analysis system specifically with reference to the software engineering principles utilized and the modular framework within with a flexible implementation can be realized. We shall highlight some of the implemented modules and, using two actual test batteries as examples, demonstrate the flow of information between each module. We shall also show the additional reporting and analysis features implemented for clinician support and describe how the framework can be utilized for more generic applications of handwriting/drawing analysis.
