Action Research Proposal - Thesis Example Content analysis will be used for analysing data that is going to be obtained from the study. There is a lot of information on Instructional Rounds about how to do them, prepare them and the reasoning behind them. However, there is little information that gets directly back to the teacher. It is because of this, I find it necessary to conduct research in order to establish how instructional rounds directly influence instruction in the class room. In this study, I will specifically focus on the teachers since some of them are stuck in their old ways, refusing to try new approaches while others are willing to give a try to anything new. However, most teachers fall between the two categories and this is the reason why this study seeks to investigate the measures that can be taken to implement instructional rounds in order to improve instructional competencies in teaching students from different backgrounds. The study will also investigate how instructional rounds in teaching can enhance the teaching profession in different contexts. The study will mainly focus on Union Groove Middle School which has a current enrolment of 876 with a composition of 416 males and 460 females. The ethnicity composition of the students is as follows: White (325), Pacific Islander (10), Black (224), Asian (45), Indian (6) and Hispanic (200). The number of students with 504 plans stands at 82, and the number of at risk students is 224. The total number of students in special education is 85. The composition of the total population of the students is ideal for conducting a study about the effectiveness since it is comprised of six ethnic groups as mentioned above. Usually, teaching students from diverse ethnic backgrounds can be challenging since these people have different levels of understanding by virtue of their experiences. Elements such as language and cultural differences also contribute to the level of understanding of the students in as far as

How Eukaryote Cells Came into Life Essay Example | Topics and Well Written Essays - 1500 words

How Eukaryote Cells Came into Life - Essay Example Prokaryotes had been first found around 3.5 billion years, which is just a billion years following the formation of the earth’s crust. Till today these life forms remain to be the most profuse ones, and since they have a very varied metabolism as compared to the eukaryotes, we can find a great many kinds of prokaryotic types. Since eukaryotic cells comprise of a huge majority of multi-cellular organisms and other complex cells, their origin has been considered a great highlight in the evolution of life. It is not really possible to determine when exactly these cells came into existence but according to Knoll (2006) it was around 1.6 – 2.1 billion years ago that eukaryotic cells took form. Certain acritarchs have been said to have originated 1650 million years ago and Grypania is an alga that was probably discovered to be approximately 2100 million years back. Besides this, it is the opinion of biomarkers that stem eukaryotes had come into being even before this and, as an example, steranes were found to be present in Australian shales almost 2.7 billion years ago. In 1966 the endosymbiosis theory was proposed by Lynn Margulis and he said that the prokaryotic cells and the initial eukaryotic cells lived together. At the beginning there was much hesitation in the acceptance of this theory. Eukaryote cells are more complicated and are set inside membranes while prokaryote cells do not have any membrane bound organelle. Another difference between these two cells is that eukaryotes have a cell nucleus while prokaryotes do not. This nucleus contains the DNA of the cell. Secondly, the size of eukaryotes is bigger as in the width and thus the volume is also more as compared to the prokaryotes. Chromosomes are present in eukaryotes which are actually where the DNA is. The movement of eukaryotes are controlled by motile cilia, also called flagella; and the flagella of eukaryotes are quite simple as compared to those in prokaryotes. Besides this, eukaryotes are like prokaryotes in respect to the plasma membrane and its function, but there is slight difference in the setup. Symbiosis as a mutually beneficial relationship happens when there are two species living together or closely for very long durations. This association is actually known as symbiotic, the word meaning to live together. Now there are different kinds of such a relationship and one is mutualism in which both the species get something out of the relationship. A very common example is that between plants and fungi. MAIN BODY Eukaryotes have been explained through various ways. An attempt has been made to explain the origin of these cells through the endosymbiotic theory as well, which was first proposed in 1905. This theory is basically concerned with the mitochondria, plastids and similar other organelles of the eukaryotes. This theory proposes that there were some specific kinds of organelles which actually came into being as free living bacteria. These were then taken within another cell as endosymbionts. Thus took place the development of cells and proteobacteria resulted in mitochondria while cyanobacteria lead to chloroplasts. In 1966 this theory was again proposed by Lynn Margulis and he said that the prokaryotic cells and the initial eukaryotic cells lived together. At the beginning there was much hesitation in the acceptance of this theory. Eukaryotes have double membranes around them. Within these membrane-bound compartments take place certain metabolic activities. As
