The ADDIE model consists of five phases: Analysis, Design, Development, Implementation, and Evaluation. Development is not a key component of the ADDIE model.

The primary goal of instructional design is to ensure that students learn the material. This can be achieved through the use of effective teaching strategies, engaging and interactive learning experiences, and a positive learning environment.

Social Learning Theory emphasizes the importance of active participation and social interaction in the learning process. It suggests that individuals learn by observing and imitating the behavior of others.

Formative evaluation is used to identify areas where the educational technology product or program can be improved. It is conducted during the development and implementation phases of the ADDIE model.

Text is not a type of instructional media. Instructional media refers to the various tools and resources that are used to deliver instruction, such as audio, video, graphics, and animation.

The learner plays an important role in the design of educational technology. They can provide feedback on the educational technology product or program, participate in the development and implementation of the educational technology product or program, evaluate the effectiveness of the educational technology product or program, and use the educational technology product or program to learn.

The personal preferences of the instructor should not be a factor to consider when selecting instructional media. The focus should be on selecting instructional media that is appropriate for the learning objectives, the characteristics of the learners, the cost of the instructional media, and the availability of the instructional media.

Synchronous learning occurs in real time, while asynchronous learning occurs at the learner's own pace. Synchronous learning involves face-to-face interaction, while asynchronous learning involves online interaction. Synchronous learning is more effective than asynchronous learning for some types of learning, while asynchronous learning is more flexible than synchronous learning.

Technology plays a vital role in educational technology. It provides tools and resources for teaching and learning, facilitates communication and collaboration between teachers and learners, creates engaging and interactive learning experiences, and assesses student learning.

Evaluation is an essential part of educational technology. It helps to ensure that the educational technology product or program is meeting its objectives, identify areas where the educational technology product or program can be improved, provide feedback to learners on their progress, and measure the impact of the educational technology product or program on student learning.

The design of educational technology is associated with a number of challenges, including the need to keep up with the latest technological developments, the lack of resources and funding, the difficulty in creating engaging and interactive learning experiences, and the need to ensure that the educational technology product or program is accessible to all learners.

Some of the trends in the design of educational technology include the use of artificial intelligence and machine learning, the development of personalized learning experiences, the use of augmented reality and virtual reality, and the focus on mobile learning.

The future of educational technology is bright. Educational technology will become more integrated with artificial intelligence and machine learning, more personalized and adaptive, more accessible to all learners, and more engaging and interactive.

The educational technologist plays a vital role in the design, development, implementation, evaluation, and research of educational technology solutions.
