There are 8 videos of classroom teaching and diversity issues. You need to watch all videos to complete the reflection paper assignment. Try to think about this in terms of either in-person teaching or virtual or a combination of videos, in-person observation, and interview of a teacher.

These videos are not to offend anyone but to discuss issues of diversity and classroom teaching. The instructor does not want to impose his own views on anyone but to allow you to study issues as a way of the learning process.

After watching the videos and interviewing a teacher or visiting a classroom, you should have enough information to write your final paper. Your final paper will include responses to the following questions:

1. Describe any observations in the classrooms or in the videos that highlighted specific classroom management rules/strategies. Make sure to identify the video(s) in your response.

2. If you were the teacher in these classes, identify at least two classroom management strategies that you would use. Be clear.

3. Finally, based on your personal experiences in-classroom observation and discussions with teachers, share your thoughts about how the classroom management strategies from this course will help you to teach all students in your future teaching assignments. Also, include some ways you could avoid possible ineffective management strategies you may have encountered or viewed in the videos.

Sample Solution

using cellulose acetate phthalate/2-butanone/Poloxamer 407 system and in two systems it was found that there is a switch between micro and nanoparticles depending on polymer concentration in internal organic phase where, as polymer concentration increased, size of produced particles significantly increased [215]. On the other hand, these results are disagreeing with those reported in Ahmed, I.S., et al.,2014 [216] who prepared poly-Ɛ- caprolactone nanoparticles by solvent displacement method and investigated the effect of polymer concentration on particle size. It was found that increasing polymer concentration from (0.5 to 0.8% w/v) at surfactant concentration (0.5% w/v) resulted in increasing particle size while, at the same surfactant concentration and increasing polymer concentration to (1% w/v) particle size decreased. Also, increasing polymer concentration from (0.5 to 0.8% w/v) at surfactant concentration (1% w/v) resulted in decreasing particle size while, at the same surfactant concentration and polymer concentration was increased to (1% w/v) particle size increased. These results were attributed to that at low polymer concentration and high surfactant concentration, the solubility of polymer in acetone/water mixture might have increased due to the solubilizing effect of the surfactant leading to slower rate of polymer precipitation and formation of larger particles. While at higher polymer concentration the effect of surfactant on solubility was less marked leading to higher precipitation rate and the formation of smaller particles [216].
The higher polymer concentration might also results in increasing viscosity of the organic phase, which might decrease the diffusion rate and might lower the rate of Ostwald ripening for the more viscous solutions so smaller particles were produced [217].
Eudragit S100 nanoparticles were smaller than those of HPMC phthalate HP55 while maintaining the same formulation conditions; this may be due to that polymer molecular weight that influences nanoparticle size as the higher polymer molecular weight, the smaller the nanoparticles [218].According to this, molecular weight of Eudragit S100 (150000 g/mole) [128] is greater than molecular weight of HPMC phthalate HP55 (78000 g/mole) [133], Eudragit S100 nanoparticles of were smaller than HPMC Phthalate HP55 nanoparticles.
