In virtual immersive environments (VIE), setting measurable objectives is essential for effective learning. Learning objectives should be designed to address specific knowledge, skills, or behaviors that students should acquire after completing the learning experience.

The measurable objectives in VIE should follow the SMART criteria, meaning they should be Specific, Measurable, Achievable, Relevant, and Time-bound. Specific learning objectives outline exactly what students should be able to do, whereas measurable objectives help assess whether the objectives have been achieved. In VIE, measurable objectives can be assessed through various means, such as quizzes, assignments, and simulations.

In addition, the measurable objectives in VIE should also consider the affordances of the technology. For instance, if the learning experience is a simulation, the measurable objectives should align with the affordances of the simulation, such as specific skills or knowledge that can be acquired through the simulation. Furthermore, the objectives should be designed to enhance the user's engagement and interaction with the VIE.

To ensure that measurable objectives in VIE are effectively designed, instructional designers should conduct a needs assessment to identify the learning goals, the audience, and the environment in which the learning experience will be delivered. This information will help in determining the most appropriate measurable objectives for the VIE.

ABCD model (Smaldino et al., 2008) is a commonly used framework for writing learning objectives. Here's an example of how the model can be applied to write an objective for a VIE:

A: Audience: The audience for this objective is a group of high school students.

B: Behavior: By the end of the VIE experience, the learners will be able to demonstrate their understanding of the physics concepts related to motion.

C: Condition: The learners will use physics simulation software to investigate the relationships between speed, velocity, and acceleration.

D: Degree: The learners will be able to explain the key concepts of motion and calculate the speed, velocity, and acceleration of an object with 90% accuracy.

Overall Objective: By the end of the VIE experience, high school students will be able to demonstrate their understanding of the physics concepts related to motion, using physics simulation software to investigate the relationships between speed, velocity, and acceleration. Specifically, they will be able to explain the key concepts of motion and calculate the speed, velocity, and acceleration of an object with 90% accuracy.

In conclusion, setting measurable objectives in VIE is crucial for effective learning. Instructional designers should ensure that measurable objectives follow the SMART criteria, align with the affordances of the technology, and are designed to enhance the user's engagement and interaction with the VIE.
