Evolution of the Hominids - 1290 Words

Modern humans are the only remaining species of the hominids, a branch of great apes which characterized by posture, dexterity, sociality and uses tools which trend towards larger and more complex brains. Early hominids, for example the australopithecines had more apelike brains and skulls, are less often thought to as human than hominids of the genus of Homo. Homo heidelbergensis are considered to be the most likely to form the line of ancestry of modern humans. Homo sapiens began to reach their modernity about 200,000 years ago. They began to exhibit behavioral towards modern era around 50,000 years ago. Humans have become the most cosmopolitan species at the earth that established their populations on all parts of earth except the smallest, driest, and coldest lands. They also permanently manned spaces in Antarctica, on area offshore platforms, and also orbiting the earth. Humans are distinguished by their relatively larger brain with its, prefrontal cortex and temporal lobes, which enable high levels of reasoning, language, problem solving, and culture through social learning. Human uses tools to a much higher degree of complexity than any other animal, and are the only known species to build fires and cook their food, as well as using cloths and also creating numerous other technologies and arts. Humans are also uniquely adept in utilizing systems of symbolic communication, such as language and art which they used for self-expression, exchanging ideas, andShow MoreRelatedHominid Evolution2435 Words   |  10 PagesHominid Evolution The evolution of hominids has been and still is a heated topic of debate.

Depression The Fastest Growing Psychological Disorder

Depression is one of the fastest growing psychological disorder. It affects a major part of the world population. According to the Anxiety and Depression Association of America (ADAA), depression is defined as a condition in which a person feels discouraged, hopeless, unmotivated or disinterested in life in general. There are two types of depression namely Major Depression and PDD (Persistent depressive disorder) (America). A major depressive episode involves an interference with the ability to work, play, eat or sleep. Also, a major depressive episode will have five symptoms namely persistent anxiety or sadness, feelings of guilt or helplessness, loss of appetite and thoughts of death and suicide etc. Some of the causes may be the death of a loved one, a romantic breakup and a medical illness etc. On the other hand, PDD is less severe than major depression but involves a lot of the same symptoms such as low energy, poor appetite, and overeating etc. According to the ADAA, the differ ence between major depression and PDD is that a person with major depression sees life as worthless and may try to end it. Whereas, a person suffering from PDD will see life as a half empty. According to the DBSA, roughly 14.8 million American adults are affected by major depressive disorder (Alliance).

Open Eyes and Wonder free essay sample

I stepped out of the gray colored elevator into the hall. In front of me stood a golden, oak-colored wall that said â€Å"Maternity†. Walking to my right, I pushed a calling bell that had a camera attached. When I informed the receptionist who I was, the doors unlocked and I pushed open the entrance to the day that changed my life. I stepped in and a green carpet with black speckles welcomed me. The walls were the color of oatmeal; the lobby smelled like witch hazel solution and diapers. After I walked through the halls for about half a minute, I found the secretary at the reception desk and informed her that it was my last day of volunteering at the hospital that summer. She spoke words of sorrow and repeatedly said that she would miss me terribly. I shared with her my feeling of not wanting to leave the hospital, and proceeded to my daily duties for the last time. We will write a custom essay sample on Open Eyes and Wonder or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Throughout that summer, the nursery had always been a sacred sanctuary for me. It had comforted me during some of the worst moments of my life. I had experienced three deaths through the course of those two months, so seeing the miracle of life happen in front of my eyes everyday had often left me in awe. When pondering upon this fact, I was called into the nursery to assist a nurse. I handed her some papers and arranged some mustard-colored binders for the new patients because it had been a busy day. There were about ten babies born within four hours; two of them were twins, and the nurses were running a marathon to finish all the work ahead of them. As I turned around after putting away the binders, I noticed one of the twins: twin B. Since it had only been about an hour after his birth, he had not even opened its eyes yet. He was about a foot and a half in length, cream in color with a head full of black hair. Suddenly, there was a slight twitch in his eyelids. His eyeballs moved . The miniature eyelashes fanned, possibly creating the slightest wave of wind possible. His blood-red lips quivered. Slowly, he opened his pale eyes: inside were two perfectly round blue balls staring at me with wonder. A subtle smile appeared on his cherry-red lips that seemed to say â€Å"I like this place so far.† These few seconds sent a comforting wind through me that blew away my past and put a clear future ahead of me. My future, I realized, was determined then. I finally understood my calling. I was destined to work in that environment where each day creates a sense of new life within me. The atmosphere does not call for the same repetitive tasks that await me each day, rather a new person, a new life, and a new story. I was meant to be a nurse practitioner surrounded by these true joys of life. What more could I ask for than to help people make the most brilliant of memories? My patients trust me to shape the most personal aspects of their lives. How could I ever be more honored? How could I ever be of more help to anyone if not by making that day the most special of all days? I walked out that day leaving behind the pain of the summer, but ever so tightly holding onto the treasured lessons I learned from the experiences. Sharing those few precious moments with my twin B enabled me to realize my passion for working with children. When I stepped into the car at 2:30 p.m. that day, I was certain t hat I wanted to repeat that same delicate moment I had with that cream-colored twin many more times. The story simply cannot end with that single occurrence because; how wonderful it is to share the very first moments of a newborn’s life.

Observing math instruction free essay sample

In every aspect of life there is a need for some kind of standard, in mathematic instruction there are two aspects of these standards, processing and constructivism. Standards are an example of what learning should occur in students. Standards are important because it gives schools and districts a goal. By incorporating standards it allows everyone involved to be aware of what needs to happen, what the teacher will teach, what the student will learn and any assessments that will be done (great schools). In my opinion standards can improve student achievement because students and parents know what information they have to learn and they can better prepare themselves. Most people like having a pattern or guide of some sort to follow because it takes the guess work out. With such good guide lines in place some people still use traditional math instruction verses constructivist programs. With tradition al instruction the teacher provides the information and is the main authoritative figure, they usually disseminate their knowledge. We will write a custom essay sample on Observing math instruction or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The students react directly to the teacher’s instruction, and the classroom atmosphere is very passive. Students are not expected to rely on prior knowledge or background for learning experience. The lessons are usually revolved around a textbook and the assessments are usually formal and informal tests. On the other hand constructivist programs are based on theory. Constructivist teachers interact with their students, promote the construction of their own learning, allow students to have points of view and encourage participation in classroom activities. The students are usually active and work in groups. Constructivism focuses on problem solving, and the application of knowledge. Finally in a constructivist setting there is the use of such tools as running records, observations and portfolios when the student is being assesses because these tools capture knowledge and comprehension of concepts (Mazarro 2009). During recent observation of a math class in an elementary school the opportunity was permitted to see if and how certain math standards were being used in the classroom. The objective of this lesson was students will be able to improve their critical thinking skill by practicing solving problems. This particular teacher was using mathematical processes. In this particular standard the student focuses on problem solving, reasoning, and proof of. This particular teacher had already pre-assigned her students with partners to work with. This evidentially was done in the very beginning of the school year so all the students were familiar with their partners. The teacher presented the students with several sceneries and the students had to develop questions that could be used. She reminded the students they should focus on what the question is asking. There were several little games already in place for problem solving strategies. One of the questions was packing for camp, what things would one need to bring. The students worked with their partner and came up with different questions. The teacher was practicing constructive response. She used pictures, and drew something that resembled a T, this tool allowed the students to visualize the questions she was asking. The question was how many ways can 36 tiles are drawn? The students seem to enjoy the exercise, and the partners they had chosen were actively engaging in exchange of ideas. The teacher had a few students in her class that were Spanish speaking, there were no special education students, disabled students. For the Spanish students there was a paraprofessional that translated and helped the Spanish students to understand the questions being asked. When the teacher was asked about differentiation she stated â€Å"they have been here for a while and they comprehend pretty well with the paraprofessional giving them assistance†. She also explained that sometimes there are special education students in the class but the same procedure takes place with the paraprofessional. As far as this lesson goes the results and expected outcomes were pretty clear. The questions were everyday questions that any of the students could identify with regardless of background or culture. There was no need to make any changes and in my opinion I would not have done anything different. I have often been surprised when doing my practicum at this particular school because there is so little technology available to students. The teacher did however use an overhead board that had some technological tools. The students would go up to this particular board and click on what they wanted to use and then preceded to write whatever their question was. This particular assignment was more or less thinking skills so the use of technology was not necessarily needed. The teacher had different little rhymes she would use to jog the students memory. She allowed time for each question to be answered and when the class was over the students didn’t appear to be as though they were rushed. The assessment of the learning was through group activity so it was based on constructivism. The students were also given test prep questions as homework. The class was mostly based on allowing students to process information and practice problem solving. The best way to describe the assessment was observations. I did notice the teacher kept some type of record of student activity. The opportunity was not awarded to investigate this record. After the lesson and the practicum experience it has become very clear that the use of standards are a very important aspect of education. Standards are the baseline for most things we do in life. The math standards are clear and concise, so the use of these standards has become practical and easy for most teachers to use. The use of standards can make teaching a better experience on my opinion. According to several statistics noted student achievement has greatly improved, but the use of these standards is slow to catch on. The reasoning for this is many teachers have been in the system for a while and are not as open to using updated information. As more new teachers are put into the system the use of these standards will take precedence
