What are the 3 laws of reflection of light?
Any mirror obeys the three laws of reflection, flat, curved, convex or concave.
What are the 2 laws of refraction of light?
The two laws followed by a beam of light traversing through two media are: The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.
What does Snell’s law say?
Snell’s law, in optics, a relationship between the path taken by a ray of light in crossing the boundary or surface of separation between two contacting substances and the refractive index of each. Snell’s law asserts that n1/n2 = sin α2/sin α1.
What are the four reflective practice models?
Each model of reflection aims to unpick learning to make links between the ‘doing’ and the ‘thinking’.
- Kolb’s learning cycle.
- Gibbs’ reflective cycle.
- ‘Reflection-in-action’ and ‘reflection-on-action’
How many type of reflection are there?
Two
How many reflective models are there?
4 Models
Which reflective model is the best?
Gibbs’ Reflective Cycle. One of the most famous cyclical models of reflection leading you through six stages exploring an experience: description, feelings, evaluation, analysis, conclusion and action plan.
What are the pros and cons of the reflective models?
Pros and Cons of Reflective Practice Models
| Pros | Cons |
|---|---|
| Provide a useful starting point for those unsure where to begin | In the real world you may not start at the ‘beginning’ |
| Allow you to assess all levels of a situation | Models may not apply in every situation |
Why do nurses use Gibbs model of reflection?
Reflection is a key aspect of the personal and professional development that nurses are required to undertake to keep pace with the changing nature of practice. It helps ensure safe and effective evidence-based care by allowing nurses to constantly improve their skills.
What are the disadvantages of reflective practice?
Limitations to reflective practice include:
- Not all practitioners may understand the reflective process.
- May feel uncomfortable challenging and evaluating own practice.
- Could be time-consuming.
- May have confusion as to which situations/experiences to reflect upon.
- May not be adequate to resolve clinical problems.
What is difficult about a reflective exercise?
Perhaps one of the biggest barriers to reflection is you! Unfortunately this is one of the hardest to overcome but it can be done. Being reflective takes a certain level of self-insight which can be uncomfortable for some people, especially if you are not used to it.
What are the barriers of reflective practice?
The top 5 barriers to reflective practice were “Lack of time” (n=73, 68.9%); “Lack of training” (n=44, 41.5%); “Lack of guidance” (n=39, 36.8%); “Lack of knowledge” (n=38, 35.8%); and “Not supported by organizational culture” (n=37, 34.9%).
What are the advantages of reflective practice?
Reflective practice has huge benefits in increasing self-awareness, which is a key component of emotional intelligence, and in developing a better understanding of others. Reflective practice can also help you to develop creative thinking skills, and encourages active engagement in work processes.
What is reflective thinking?
Critical thinking and reflective thinking are often used synonymously. Dewey (1933) suggests that reflective thinking is an active, persistent, and careful consideration of a belief or supposed form of knowledge, of the grounds that support that knowledge, and the further conclusions to which that knowledge leads.
Why is being reflective important?
Reflecting helps you to develop your skills and review their effectiveness, rather than just carry on doing things as you have always done them. It is about questioning, in a positive way, what you do and why you do it and then deciding whether there is a better, or more efficient, way of doing it in the future.
