When I try to communicate through text message, the most common problem I experience is that the recipient of my message doesn’t understand the tone I am using when writing my message. Even though I recognize that this is a potential issue when communicating in writing rather than speaking, I continue to make this mistake. For example, there have been times that I’ve attempted to make a joke to my friends, who took the meaning of what I said literally. Unfortunately, it is difficult to use rhetorical devices while communicating in writing. A reasonable way to resolve this problem would be to avoid any assumptions in my message and state what I mean clearly.

An additional problem that I have experienced when writing text messages or emails quickly is that these scripts do not include proper grammar. This leads to misleading messages because the use of a comma is important to ensure that the words used are assigned the proper meaning. A related issue is the formation of typos. When using a smartphone, typing one word incorrectly means that the word could become completely transformed. Other related issues include sending a message to the recipient before it has been completed and sending a message to the wrong individual. These are embarrassing mistakes that could be easily avoided if the writer takes time to write the message and revises it before it is sent. This is especially important when the messages are sent in a professional or academic setting, as errors tend to reflect the personal character of the individual who sends them.

The process being examined is mitosis, which is another word for cellular division. It is important to understand mitosis because it is involved in the growth and repair of cells. Mitosis has four distinct steps, which includes prophase, metaphase, anaphase, and telophase (Morgan, 2007).

The first step of mitosis is called prophase. This step occurs when the chromosomes inside of the cell decondense and become distinct units. The sister chromatids become apparent, and cell components such as the centromeres position themselves to facilitate the continuation of this process. Prophase transitions into a phase known as metaphase.

The second step of mitosis is called metaphase. This step occurs when the sister chromatids, comprised of chromosome pairs, are pulled to the center of the cell by the mitotic spindle, which is controlled by the centromeres. After sister chromatids are aligned, the cell continues to prepare for division. The next step of mitosis that facilitates this process is called anaphase.

The third step of mitosis is called anaphase. In this step, the chromosome pairs separate and travel to opposite poles of the cell. This occurs in order to ensure that each cell that results at the end of mitosis will have the same number of chromosomes. Anaphase transitions into a phase known as telophase.

The fourth and final step of mitosis is called telophase. In this step, a barrier forms around each separate step of chromosomes and the cells start to divide. Following telophase, the single parent cell divides into two separate daughter cells through a process known as cytokinesis, which is the division of the cytoplasm.

At the beginning of mitosis, there is one single parent cells. After all four steps of this process are complete, there are two genetically identical daughter cells (Freeman, 2002).

The technical instructions are effective because the title promises exactly what the instructions deliver; the ability to replace the iPhone 4S display screen (Galan, n.d.). The background is adequate for the intended audience because it assumes that readers do not have advanced knowledge of phone engineering. It enables readers to understand what to do because there is simple wording and pictures that demonstrate the actions that viewers would need to make. While the definition and purpose of each step is given and all obvious steps are omitted, there are not proper cautions or warnings. It is important to consider that the individual replacing the cell phone screen must take steps to ensure that the glass does not break, which could potentially cause a wound. Visuals are consistent and adequate at explaining the steps. All of the information provided appears to be accurate based on my understanding of iPhone construction.

The introduction is brief and to the point. The instructions follow the exact sequence of steps, although some steps are grouped together when it may have been beneficial for them to be separate. The information for each step is provided in the form of a list, so the following step can be found underneath the prior one. A layered approach was not utilized, although the conclusion was adequate because it demonstrates how the final product should appear. However, the section is not clearly labelled “conclusion”, which is a disadvantage.

Many of the steps have long sentences. Even though this is familiar material, this causes the steps to be somewhat confusing. Each step begins with an action verb, which allows viewers to understand what they should be doing. Instructions are in the active voice and include notes on what the person should be doing in addition to what they should have done prior to the step. Transitions are adequate for marking time and sequence.

Headings do not clearly indicate to readers what they should expect. Steps are double spaced within and there is a paragraph break between. The design is simple, but seems longer than necessary. The occasional warnings are clearly set aside.

The speaker I selected to analyze was Lizzie Velasquez who gave a TED talk on body image (Velasquez, 2013). The characteristics that stood out most to me for this speaker is that:

1) She created an interest in the topic. To do so, she provided listeners with her own personal life story, which is incredibly difficult due to her rare disease.

2) She dressed appropriately. Despite her “ugly” appearance because of her disorder, she dressed professionally and had her hair styled.

3) She had good posture and eye contact. Even though she referred to the fact that she was blind in one eye in the talk, she appeared to be looking at the audience throughout the speech.

4) She avoided needless digressions. While she would tell stories, these would support her point instead of distract from it.

5) She showed proper enthusiasm by showing how the topic relates to her own personal life and that of others

6) She did not keep the audience actively involved because she asked rhetorical questions instead of answerable questions.

7) She did not interact with the audience and the speech was more of a monologue.

8) She did not answer questions concisely and convincingly because she did not invite questions.

9) She seemed in control of the speaking situation because she always seemed that she knew what she would say next.

10) She stayed on course because all of the information she provided helped her demonstrate her main point in a sequential manner.
