Basic Directing Workshop.
Some of the things I've learned is; what is a film; what is a director; what are the role of the director; basic elements in making a film. Direct Teng taught us all about the life of a director. How to become a director and what are the trials and difficulties they encounter. We also viewed some of his films and Direct Sheron's film. We did some group activities to enhance our skills in basic directing. Direct Teng taught and demonstrate to us some of the camera movements, different types of shots. For me, the Workshop was very interesting and very enjoy, I hope that there will be more seminars and workshops for us student.

Computer Aided Instructio (CAI)
Diverse and rapidly expanding spectrum of computer technologies that assist the teaching and learning process. CAI is also known as computer-assisted instruction. Examples of CAI applications include guided drill and practice exercises, computer visualization of complex objects, and computer-facilitated communication between students and teachers. The number of computers in American schools has risen from one for every 125 students in 1981 to one for every nine students in 1996. While the United States leads the world in the number of computers per school student, Western European and Japanese schools are also highly computerized.
Computer-aided instruction packages are effective for many reasons. One of the most important reasons is that students like learning in the environment that the computer has to offer. CAI packages of today are much more user-friendly and entertaining than their predecessors. “These technologies move us light years beyond the tedious drill that early educational software promoted, and allow highly engaging activities like multimedia simulation.” (Gifford, 1993) Students can now work at their own pace regardless of the level at which they are supposed to be. This promotes self-confidence because it gives the student a feeling of control over what they are learning. “The computer has allowed the student to become a more active participant in his/her education...” (Matray & Proulx, 1995)
CAI technology has brought with it drastic changes to the conventional classroom/laboratory. Teachers, students and parents have all been required to change their role in education. The teacher’s role has changed “from that of an oracle of knowledge to a guide and/or resource person.” (Matray & Proulx, 1995) As previously mentioned, students have changed from complacent, passive onlookers to active participants in the classroom. CAI has encouraged students to “explore more and memorize less.” (Matray & Proulx, 1995) Now more than ever, parents are strongly encouraged to take an active part in their child’s education. Since the software programs are available on the market, parents have the chance to bring education into the home at an affordable price.
Information that helps teach or encourages interaction can be presented on computers in the form of text or in multimedia formats, which include photographs, videos, animation, speech, and music. The guided drill is a computer program that poses questions to students, returns feedback, and selects additional questions based on the students' responses. Recent guided drill systems incorporate the principles of education in addition to subject matter knowledge into the computer program.
Computers also can help students visualize objects that are difficult or impossible to view. For example, computers can be used to display human anatomy, molecular structures, or complex geometrical objects. Exploration and manipulation of simulated environments can be accomplished with CAI—ranging from virtual laboratory experiments that may be too difficult, expensive, or dangerous to perform in a school environment to complex virtual worlds like those used in airplane flight simulators.
CAI tools, such as word processors, spreadsheets, and databases, collect, organize, analyze, and transmit information. They also facilitate communication among students, between students and instructors, and beyond the classroom to distant students, instructors, and experts.
CAI can dramatically increase a student's access to information. The program can adapt to the abilities and preferences of the individual student and increase the amount of personalized instruction a student receives. Many students benefit from the immediate responsiveness of computer interactions and appreciate the self-paced and private learning environment. Moreover, computer-learning experiences often engage the interest of students, motivating them to learn and increasing independence and personal responsibility for education.
Although it is difficult to assess the effectiveness of any educational system, numerous studies have reported that CAI is successful in raising examination scores, improving student attitudes, and lowering the amount of time required to master certain material. While study results vary greatly, there is substantial evidence that CAI can enhance learning at all educational levels.
In some applications, especially those involving abstract reasoning and problem-solving processes, CAI has not been very effective. Critics claim that poorly designed CAI systems can dehumanize or regiment the educational experience and thereby diminish student interest and motivation. Other disadvantages of CAI stem from the difficulty and expense of implementing and maintaining the necessary computer systems. Some student failures can be traced to inadequate teacher training in CAI systems. Student training in the computer technology may be required as well, and this process can distract from the core educational process. Although much effort has been directed at developing CAI systems that are easy to use and incorporate expert knowledge of teaching and learning, such systems are still far from achieving their full potential.
