Brief Lesson Description:
Growth and differentiation of cells in the body normally are precise and regulated. When cells grow uncontrollably, mutations can occur and cancers can form. As a mechanism of introducing the biological basis of cancer, this tasks has been developed to help students gain a conceptual understanding of how the process of mitosis not only provides a complete set of genes to each somatic cell, it can result in cells that divide abnormally resulting in cancer.

Objective: Students will recall conflict terms and prior knowledge of conflict and resolutions in various texts.
As a teacher in training, I have very limited in-classroom experience and depend heavily on the expertise of professors as well as a variety of books and articles published on education. I am convinced that a learner centered approach to instruction is of fundamental importance and that it will inform most teaching decisions I will need to make to become an effective educator. Knowing as much about the students before school even begins will help structure the content material and guide the instruction methods. Along with this, knowing what the school provides in terms of environment and materials will help formulate a plan to give students every possible opportunity for achievement and success. Wong (2005) defines classroom management as “all of the things that a teacher does to organize students, space, time and materials so that student learning can take place” (p. 84).
Cancer has been an active concern in our society for the past couple decades, since we truly discovered the nature of cancer and the potency it brings along with it. However, it was not until the mid-20th century that scientists were beginning to truly understand the origin of cancer. Scientists dating back all the way to the Renaissance, when they first began performing autopsies to learn more about the human body and form, noticed abnormalities but it never clicked that it was something much worse than it seemed. Research has continued since then, and it has continued to thrive even to this day. When James Watson and Francis Crick discovered DNA and it’s chemical structure in 1962, it opened up doors that even they could not expect. With the understanding of DNA and how it affected the way we look at life, came the beginning of the understanding of mutated DNA (which is a cause of the growth of cancerous cells). In this past century, researching scientists discovered that cancer is linked with the DNA that resides in a cell’s nucleus. By ways of damage to the cells via chemicals or radiation, or even introduction of a new DNA, the cancerous cells begin to form and duplicate. We are learning more and more about cancer and how to fight it, but we still have much more to learn.
Cancer is the term used to describe a group of diseases consisting of hundreds of ailments and although there exists so many different types of cancer, they all begin in a similar way. The body is made up of over a trillion cells, and cancer is the uncontrolled growth of malfunctioning cells in the body (Dawson, 1996). “Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person’s life, normal cells divide faster to allow the person to grow. After the person becomes an adult, most cells divide only to replace worn-out or dying cells or to repair injuries” (American Cancer Society, 2012).
All organisms are made of cells that grow by cell division. An adult human being consists of about 100000 billion cells. Dying cells are replaced by a large number of unceasingly dividing cells. A cell duplicates its chromosomes, segregates the chromosomes, and divides into two. These ordered sequences of events are called a cell cycle. 2001 Nobel Prize in Physiology or Medicine to Hartwell, Hunt, Nurse and 1998 Lasker Prizes in Basic Medical Research to Hartwell, Masui, Nurse have made important discoveries about the regulation of a cell cycle. Understanding the regulation of a cell cycle is seminal to understanding why and how cancer cells are formed. In this review, I focus on how these crucial discoveries made progress in understanding cell cycle regulation and leading to understanding cancer cell and cancer therapy.
Healthy cells grow and divide in a way to keep your body functioning properly. But when a cell is damaged and becomes cancerous, cells continue to divide, even when new cells aren't...
There have been extraordinary progresses in identifying cancer at the cellular level and the question of how cancer cells develop are no longer a secret. Although there are many different types of cancer and almost every tissue can turn into malignancies, the basic processes of how cancer arises are very similar. While normal body cells follow the orderly path of cell cycle and only reproduce when instructed to do so, cancer cells violate the schedule and ignore instructions, it fails to follow the orderly enzymatic reaction which is responsible for the deletion of cells with damaged DNA (Kerr et al. 1994). Cancer cells enter cell cycle repeatedly until it will eventually disrupt the function of tissues and organs that are essential to the organism (Weinberg 1996). Not all types of cancer are fatal, benign cancer is a type of cancer which stays in one location only, in another word it will not m...
Objective 1 (Explaining & Understanding): Students will review the definitions of bias and point of view. Students will be taught how to determine bias and point of view (word choice).
By harnessing this normal cell process, scientists hope to have found an effective way to combat cancer. Cancer is a disease that affects human somatic cells. It causes the cells to divide uncontrollably and form masses known as tumors. There are two different types of cancer tumors. Some tumors are benign, and other tumors are malignant.
The most challenging part of creating a unit plan is knowing the depth of information to provide for the students, especially when creating a unit plan for 8th graders. I am not always sure how far I should go in my curriculums and because I already know a lot of in-depth information about my lessons, I second guess myself on whether I am adding enough objectives for students to learn. I also believe that time management might be an issue for me as well. It is easy for me to get distracted when certain topics arise and since so many topics in science are related to each other. I fear that I might add side notes that may confuse my students, shift their focus or lose their interest.
Learning Theories and Instructional Strategies The lessons contained in this unit of instruction were based upon Madeline Hunter’s Seven Steps of Lesson Plan Formatting. This lesson plan format is a proven effective means for delivering instruction. When designing lessons, the teacher needs to consider these seven elements in a certain order since each element is derived from and has a relationship to previous elements. It should be noted that a lesson plan does not equal one class period.
This I Believe Philosophy statement will include my thoughts and beliefs about classroom management with comparison to other theorists’ models. The major theorists that will be mentioned are Barbara Coloroso, Linda Albert, and Lee & Marlene Canter. I highly agree with the Canter’s and Coloroso’s models of classroom management because it best fits my personality as an individual teacher. I believe that an affective classroom management plan is first practiced and then modeled for improvements. My ultimate goal for my Classroom Management Plan is to model self-discipline by teaching it through my daily actions so that students may be able to self-manage themselves accordingly.
In this essay, I will talk about the components of a lesson plan, the benefits of planning with clear and appropriate goals, selecting age-appropriate goals and objectives that align with state academic content standards, and selecting goals and objectives that are differentiated for varying abilities and learning styles and for multiple intelligences.
At the core of every great teacher there is a strategy for teaching, a plan to be followed. For those lucky few that naturally have the ability, and personality to promote learning, the plan to be followed comes almost instinctively; for other there are lesson plans. Now, the ideal lesson plan will provide step by step instructions for any teacher, no matter their experience or personality, to effectively teach a subject. Yet, much like theories in science, when put to the test, some will inevitably fail. Still, every plan has some type of yield, for this lesson plan it feel between a good and bad rating of 82%. Meaning, it was not the best, nor was it ultimately average at or around 70%, so hopefully with a few minor tweaks this lesson plan
