Create inclusive learning environments that demonstrate respect and value of diverse backgrounds.

/in /by

In this course, you will consider diversity and multiculturalism. The two course competencies related to these topics are:

  1. Create inclusive learning environments that demonstrate respect and value of diverse backgrounds.
  2. Incorporate multicultural perspectives into curriculum, instruction, and assessment.

Consider these competencies and complete the first two columns of a KWL chart about them. A KWL chart is a way to activate background knowledge and to stimulate thinking about a topic; the K stands for what you know about the topic and the W stands for what you want to know about the topic. Using the KWL chart template linked in the Resources, complete the K and W sections. Post the chart to the discussion board. Then discuss the following:

  • What content related to these topics feels “solid” to you? In other words, about which content do you have the firmest knowledge and experience?
  • What about these topics feels “muddy” to you? In other words, with which topics do you have less knowledge and experience?
  • How do this knowledge and the areas of gap affect your instructional practice?
  • How would you and your students benefit if you strengthened your knowledge and skills in this area?

For this discussion, you are not required to cite sources. The discussion is asking you to assess the state of your own knowledge, so there are no right or wrong answers. However, if you wish to make reference to academic literature to enrich your discussion, you are encouraged to do so.

Describes the cultural identifiers discussed in the articles.

/in /by

Throughout this course, you will be working on a paper 750-1,000 word research paper on a controversial topic involving a cultural identifier and the implications for K-12 public education. Your first draft of the research paper will be due in Topic 4 when you will be required to submit it in a CLC assignment for peer review, and your final version will be submitted in Topic 7.

In this assignment, you will identify and summarize research relating to the topic of your paper. Begin by reviewing the list of cultural identifiers found in Topic Materials.

Identify a controversial topic such as transgender bathrooms, same-sex relationships, religious clothing, etc. in K-12 education that involves one or more of the cultural identifiers. This topic should include two or more viewpoints that are for and against the issue.

Research a minimum of three scholarly sources from the last 3 years and submit a 500-750 word summary that includes the following:

  1. Describes the cultural identifiers discussed in the articles.
  2. Summarizes the historical background of the cultural identifiers and associated controversial topic in K-12 education.
  3. Identifies arguments presented for and against the issue.
  4. Discusses any associated injustices arising from the issue.
  5. Describes how teachers and students are affected by the cultural identifiers and associated controversial topic.
  6. Summarizes solutions and/or proposed solutions to associated injustices.

Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center.

This assignment uses a rubric. Review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

LABEL THE PARTS FROM PRESENTATION OR TEXT

1. Eukaryotic cell cycle is divided into two major phases: interphase and cell division

2. Interphase is the stage where the cell acquires nutrients from its environment, grows and duplicates its chromosomes it contains three sub phases

G1_ a newly formed daughter cell enters this stage, and carries out activities like: it grows in size, specializes to perform specific function and it decides whether to divide or not, and enters the next phase

S-phase: DNA synthesis takes place via semiconservative replication

G2: cell grows some more and then synthesize the proteins needed for cell division.

Cell division: cell carries out either mitosis or meiosis’ in order to form new daughter cells

2. Explain the process of Mitosis.

Mitosis consists of nuclear division followed by cytoplasmic division.

Mitosis occurs in the following phases

1: Prophase is the first phase, duplicated chromosome condense, spindle microtubules form , chromosomes are captured by microtubules

2 : Metaphase – duplicated chromosome are connected to spindle fibers leading to opposite poles of the cell. Microtubules shorted and lengthen until each chromosome lines up along the equator of the cell

3: Anaphase- sister chromatids formed during S-phase separates becoming independent daughter chromosomes, one of the 2 daughter chromosomes from each original parental chromosomes move to each pole of the cell

4: telophase- spindle fibers disintegrate nuclear envelope forms around each group of chromosome. The DNA revert to its original extended state, nucleoli begin to form

5: cytokinesis- microfilaments attached to membrane form a ring around the equator of the cell, constricts dividing the cell, in plants cell plate is formed forming 2 daughter cells

3. Compare the process of cytokinesis in plant cell and animal cell.

Cytokinesis in animal cells

a. Microfilaments attached to the plasma membrane form a ring around the equator of a cell . The ring contracts and constricts the cell’s equator

b. Eventually, contraction of the ring pinches off the membrane, forming two daughter cells, each with a nucleus identical with the other

c. Following cytokinesis, animal cells enter G1 of interphase, thus completing the cell cycle

Cytokinesis in plant cells

a. Stiff plant cell walls prevent the “pinching off” of cytokinesis seen in animal cells, which only have a plasma membrane

b. Instead, carbohydrate-filled vesicles assemble along the cell’s equator, between the daughter nuclei

c.The vesicles fuse into a continuous flattened sac, surrounded by plasma membrane and filled with sticky carbohydrates .This is called a cell plate

d. The plasma membranes of the plate fuse with the plasma membrane of the cell, forming two cells, with the carbohydrate in between becoming part of the cell wall

e. As in animals, plant cells enter G1 of interphase following cytokinesis, thus completing the cell cycle

4. Describe in humans the three categories of cells, based on their ability to divide and differentiate

1.Stem cells :

– have two important characteristics: self-renewal, and the ability to differentiate into a variety of cell types

-Stem cells self-renew because they retain the ability to divide, perhaps for the entire life of the organism

-Some stem cells in early embryos can produce any of the specialized cell types of the entire body

2.Other cells capable of dividing

-Some cells other than stem cells are capable of continuing to divide, but typically differentiate into only one or two different cell types

· Dividing liver cells, for example, can only become more liver cells

3. Permanently differentiated cells

· Permanently differentiated cells differentiate and never divide again

· For example, most heart and brain cells cannot divide

5. Complete the following table to compare mitosis and meiosis

mitosis Meiosis
a. Number of chromosomal duplications
b. Number of cell divisions
c. Number of daughter cells produced
d. Number of chromosomes in daughter cells
e. How chromosomes line up during metaphase
f. Genetic relationship of daughter cells to parent cells
g. functions performed in the human body
