Summary
Assessing undergraduate interdisciplinary science understanding is challenging. Current writing assessments may not fully capture students
Area of Science:
- Interdisciplinary science education
- Undergraduate science curriculum development
- Assessment of scientific literacy
Background:
- Effective education reform aims for undergraduates to integrate knowledge across disciplines for real-world problem-solving.
- Current assessments for interdisciplinary thinking in science are limited.
- Understanding how science faculty assess interdisciplinary science is crucial.
Purpose of the Study:
- To survey science faculty on their methods for assessing students' interdisciplinary science understanding.
- To evaluate the effectiveness of a social science rubric for assessing undergraduate science writing assignments.
- To explore the alignment between assignment scores and students' verbal understanding of interdisciplinary science.
Main Methods:
- Survey of science faculty regarding assessment practices.
- Application of a social science interdisciplinary rubric to 71 undergraduate science writing assignments.
- Semistructured interviews with 25 students to compare rubric scores with verbal understanding.
Main Results:
- Individual writing-intensive activities are the most common assessment (69%).
- The preexisting rubric's constructs did not fully capture interdisciplinary science competency in this population.
- An interdisciplinary framework may be a more suitable model for assessment development.
Conclusions:
- Current writing assessments may not adequately measure interdisciplinary science thinking.
- A new assessment instrument, guided by an interdisciplinary framework, is needed.
- Developing accurate assessments is key to fostering interdisciplinary science education.

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...

The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.

Measurement is an indispensable part of analytical chemistry. The result of measurement helps quantify a substance's physical property and compare it with the physical property of another substance. Each measurement comprises two components - a number indicating the magnitude and a unit of measurement as a standard for comparison. Further, the same quantity can be measured using different units of measurement, which leads to differences in magnitude.

03:37Uncertainty in Measurement: Accuracy and Precision
99.1K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...
