Reliability and Validity01:29

Reliability and Validity

13.7K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Tooth Anatomy

2.1K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Virtual Work01:20

Virtual Work

1.3K
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Data Validation01:03

Data Validation

6.3K
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
Nursing assessment guides are generally based on holistic models rather than medical...

Data Validation

Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
Key parameters for method validation include:

What is an Experiment?01:12

What is an Experiment?

17.4K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Area of Science:

  • Dental Education
  • Educational Technology
  • Augmented Reality

Background:

  • Emerging technologies like augmented reality (AR) and virtual reality (VR) offer new avenues for dental education.
  • A Virtual Dental Library and an AR virtual tooth identification test were developed at a U.S. dental school.

Purpose of the Study:

  • To investigate the validity of the AR virtual tooth identification test.
  • To evaluate user experience with this virtual testing method.

Main Methods:

  • The AR test scores were correlated with real tooth identification tests, quizzes, final exam, and course grades.
  • A survey assessed student perceptions of the AR tool.
  • 109 first-year dental students were invited; 93 participated.

Main Results:

  • The AR test showed positive correlations with real tooth identification tests (r=0.410), combined real test scores (r=0.545), the final exam (r=0.489), and overall course grade (r=0.661).
  • Students reported difficulties viewing/manipulating images and experienced technical issues with smartphones.
  • Survey responses indicated limited student support for the AR tool.

Conclusions:

  • The AR virtual assessment tool demonstrated criterion validity for tooth identification.
  • Despite technical and usability challenges, AR holds potential for dental assessment.
