An assessment is a measure of what a student has learned. It is defined as how well a student has mastered a section of content. Also, professors can use grades to assess student progress and mastery of skills. In this week’s lesson 337, we studied the difference between summative assessment and formative assessment.

By definition, the most straightforward understanding is that a summative assessment is an assessment of students’ mastery of a subject at the end of a year or a unit of instruction. On the other hand, formative assessments are provided during the learning process to determine student progress toward learning objectives. Both types of assessments are common in most of our courses, regardless of major or field. As a student, I prefer formative assessment to summative assessment, which is usually not in the form of a grade because it is given during the learning process. Its primary purpose is to detect whether the student is making progress toward the ultimate goal of skill mastery. In this process, the teacher can determine the level of student learning and provide timely assistance. For example, in my econ203 course, the professor gave us 1-2 questions (which would not be scored), mainly in multiple-choice format, and the system automatically tallied all the answers after the students chose them. At the same time, the instructor explained why the options were wrong based on the tally. I especially liked this form of formative assessment because not only did we get not to be graded, but we also got to know in real-time what we did wrong, which was a great way to build a foundation for our ultimate goal.

But both formative assessment and summative assessment can help students know where they are lacking, but in college courses, if you make a mistake in the summative assessment, you don’t get a second chance to update your grade. Therefore, most students will perform abnormally for fear of being nervous in midterm and final exams, but that doesn’t mean they are not on the proper instruction.

This week I will post a message about AR on multimedia learning. With the development and research of random technology, AR will also be widely used in our multimedia learning area, although there are still a few APPS using AR at present. For example, some common AR apps in daily life include Google Map, 3D virtual reality house viewing, and AR games. In the future virtual classroom, students and teachers can put on AR glasses to study topics together in the same space without physical contact. For example, the learner can use AR in interior design to learn space measurement, decoration, the physical environment, and display art through 360° and 3-D space. AR education is a new educational form and content produced by applying AR (augmented reality) technology in education. The essence of AR education is still education, but because of the combination with AR, there are many new characteristics and new teaching methods, learning methods. People can interact because AR combines the best of the virtual and real worlds. In education, AR can be applied in different scenarios, such as skill training and gamification learning. The application of AR in the training process of practical operation skills is probably the simplest. Because AR head display device develops very rapidly, it has been widely used in medical, military, commercial, and other aspects. AR teaching can provide a vibrant and three-dimensional learning environment and create a completely risk-free operating environment.

In medicine, for example, AR technology can display human organs and bones in 3D to train surgeons and medical workers. Both VR and AR can be used in digestive surgery. Patients are first scanned with CT or MRI and then simulated, and 3D modeling technology is used to generate a virtual human body that looks completely transparent. Surgeons can use fundamental surgical tools to carry out surgical training on the virtual human body, and interactive tracking can be carried out in real-time during surgical training. AR presents all the contents in 3D, which is very intuitive and vivid, helpful for students to understand and remember. For animals, plants, daily necessities, and other three-dimensional objects that are visible in reality, it is no longer necessary to imagine 3D images from planar 2D photos. AR can be visually displayed for radio waves, magnetic fields, atoms, and objects that are abstract or invisible to the naked eye, which helps to improve cognition and understanding.
AR is a good combination of the gamification of education that we studied earlier. Games are a quick and effective way to learn in many learning situations and can be very effective. The visualization and interactivity of AR can naturally design desirable gamification teaching content to significantly improve students’ learning willingness and stimulate their interest in learning. From passive learning to active learning.

AR application: Complete Anatomy

Complete Anatomy offers over 17,000 high-quality anatomical models. It covers almost all of the human anatomy, from macro to micro. Local anatomy of 206 human bones, head and neck, and blood vessels, muscles and nerves all over the body; Small to including the eyeball, teeth, aorta and other levels of micro-anatomical structures, and even the human body’s four central tissue cells, spermatogonial cells, egg cells 3D structures are included. I highly recommend this software for medical students, and you can use your iPad to explore various parts of the human body, using AR technology to display 3D anatomical models. The cool part is that AR can also show pain, bone growth, and fractures in the model.

Gamification is a particular way to increase student interest and engagement. Gamified learning adds game elements to traditional education, such as competition, music, rewards, rules, and more. The purpose of gamification is still primarily testing, but in a game without game environments. Generally, it adds game mechanics or game elements to websites to attract consumers and students.

We’ve come across many gamification platforms such as Quizzes, Kahoot, etc. As it turns out, based on my personal experience, I do think gamification makes me feel more involved. Although its primary purpose is to test students’ mastery of knowledge, I will not reject this test in this process. On the other hand, a lot of routine testing I think of it as a task. I remember a lot from an activity when I didn’t feel excluded from it.

For example, when I was in college, my professor would prepare a game for us every week, Kahoot. This is a site that fully meets the principles of gamification. First of all, each of us is an individual, and students need to earn points to compete for the top three (the top three get an extra 1% of participation points). My favorite part of this activity is its background music. Earworm’s music keeps playing during the game, which I think will be a very effective memory point. Second, the game mechanic is that the faster and correct answers are given within a limited amount of time will result in higher scores. Students will try to answer every question because of motivation (1% participation score). I think this kind of gamified learning allows me to believe in the process of learning and allows me to earn points through learning. It’s like when puppies learn to sit down and give commands and rewards. So motivation and memory points are essential in gamification. Kahoot does an excellent job of remembering facts, not just the background music, but the shapes and colors of each option (triangles are red, hexagons are blue, circles are yellow, squares are green).

However, I think what needs to be improved is that in the process of playing this game, although everyone is fair, there must be some top-notch students in the class, they may get the top three every time, if it goes on for a long time, the lagging students will lose interest and motivation. But during exploration and learning, gamification increases our interest and engagement compared to traditional testing.
