Summary
A new biotechnology literacy test was developed and validated for prospective science teachers. This 25-item multiple-choice test accurately measures biotechnology literacy, ensuring reliable assessment for educators.
Area of Science:
- Biotechnology Education
- Science Teacher Training
- Educational Assessment
Background:
- Assessing biotechnology literacy is crucial for effective science education.
- Prospective science teachers require specialized knowledge in biotechnology.
- Existing assessments may not adequately capture multidimensional scientific literacy.
Purpose of the Study:
- To develop a valid and reliable biotechnology literacy test.
- To evaluate the biotechnology literacy of prospective science teachers.
- To align the test with established scientific literacy frameworks.
Main Methods:
- A 42-item draft test was created based on Bybee's scientific literacy classifications.
- Expert review was conducted to establish content validity.
- Item analysis (difficulty and discrimination) was performed on data from 494 prospective teachers.
Main Results:
- Content validity was confirmed by expert evaluations.
- Item analysis led to the exclusion of 13 items.
- The final 25-item test demonstrated medium difficulty (p=0.40) and discrimination (D=0.41).
Conclusions:
- A valid and reliable 25-item multiple-choice biotechnology literacy test was successfully developed.
- The test is suitable for assessing the biotechnology literacy of prospective science teachers.
- This instrument contributes to improving science teacher education in biotechnology.

Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

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.

In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

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.
