Summary
A mobile app designed with cognitive load theory significantly improved healthcare students' medication calculation skills and confidence. The app was rated highly useful for learning medication dosage calculations.
Area of Science:
- Healthcare education
- Cognitive psychology
- Educational technology
Background:
- Accurate medication dosage calculation is a critical skill for healthcare students.
- Traditional methods of teaching medication calculations can be complex.
- Mobile applications offer a potential solution for enhancing learning.
Purpose of the Study:
- To evaluate a mobile app's effectiveness in improving medication calculation ability and self-efficacy.
- To explore correlations between numerical ability, self-efficacy, and calculation skills.
- To gather student feedback on the app's usability and usefulness.
Main Methods:
- A quasi-experimental study with 60 UK university healthcare students.
- App usage over 8 weeks during clinical practice.
- Pre- and post-intervention tests for calculation ability and self-efficacy, plus a numeracy test and user survey.
Main Results:
- Significant improvements in medication calculation ability (p=0.004) and self-efficacy (p<0.001).
- Positive correlations between numerical ability, calculation ability, and self-efficacy.
- Numerical ability and self-efficacy were the strongest predictors of calculation ability.
Conclusions:
- The app's design, based on cognitive load theory, effectively enhanced students' medication calculation skills and confidence.
- Students highly rated the app's usefulness for supporting medication calculation learning.
- Further research is recommended to explore the app's applicability to different learner levels and other cognitive skills.

01:17Design of Columns under a Centric Load
564
The design of columns under centric load is a fundamental aspect of structural engineering and is critical for ensuring the stability and integrity of structures. Euler's and Secant's formulas are central to understanding and calculating the critical load and deformation behaviors of columns, providing a basis for safe and effective structural design.
Euler's formula is applicable under the assumption that the column is a perfect, straight, homogenous prism, and it is operating...

01:21Design of Columns under an Eccentric Load
1.2K
Designing columns to withstand eccentric loads is a critical aspect of structural engineering, ensuring structures can support off-center loads without failure. This design process must account for the additional normal stresses introduced by eccentric loading, which can significantly influence a column's stress distribution and overall stability. An eccentric load applied to a column induces normal stresses that can be conceptualized as a combination of stresses due to an equivalent...

01:17Design Example: Calculating Safe Diameter for Wind-Exposed Disc
359
Assessing safety in wind-exposed installations is crucial to preventing potential failures. This example explores the calculation and design adjustments needed to mount a circular disc on a building facade, where wind forces are a primary concern. A 4-meter diameter disc was initially designed as an aesthetic feature facing winds at a velocity of 25 meters per second, with an air density of 1.25 kilograms per cubic meter. Given these conditions, the drag force on the disc was determined using...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

02:46Calculating the Equilibrium Constant
38.1K
The equilibrium constant for a reaction is calculated from the equilibrium concentrations (or pressures) of its reactants and products. If these concentrations are known, the calculation simply involves their substitution into the Kc expression.
For example, gaseous nitrogen dioxide forms dinitrogen tetroxide according to this equation:

02:49Calculating Standard Free Energy Changes
25.6K
The free energy change for a reaction that occurs under the standard conditions of 1 bar pressure and at 298 K is called the standard free energy change. Since free energy is a state function, its value depends only on the conditions of the initial and final states of the system. A convenient and common approach to the calculation of free energy changes for physical and chemical reactions is by use of widely available compilations of standard state thermodynamic data. One method involves the...
