Scientific research assignment #2 - Essay Example ts has planet-centric view in that is necessary to assume that the building blocks of life on Mars are analogous to that of Earth and so will be carbon-based. It was apparent in the 70s that Martian surface conditions are strongly oxidized and that this complicates efforts to detect biological life. The Urey was developed by NASA-funded researchers to work in these highly oxidized conditions. This instrument has the ability to differentiate between left-handed and right-handed amino acids with its The Mars Organic and Occident Detector (MOD) (Skelley et al., 2006). All life on Earth is comprised of chains of amino acids, although these may be to non-biological means as well. Earth life overwhelmingly tends to be comprised of left-handed amino-acids. The Urey is able to detect both types of amino acids through an oxidant instrument that has microsensors coated with various chemicals painted on like a film. Urey will be able to detect key molecules associated with life at a sensitivity roughly a million times greater than previous instrumentation, that because it is the one with the highest sensitivity for organic chemicals. In a contrasting study, Steel and colleagues (2004) are part of the interdisciplinary, international Arctic Mars Analogue Svalbard Expedition (AMASE) team formed to develop a sampling and analysis instrument that can make real-time decisions on the surface of the planet as to weather searches for life should continue in those areas. The instrument is being created to form a two-phase investigative approach; first the surface is analyzed to determine an ideal target site; following samples and analyses are used to study the actual samples collected. Candy et al. (2003) proposed that developments of instruments that extend knowledge about extraterrestrial life are able to be made using morphological biosignatures. These signatures consist of conclusive microbial fossils as well as microbial influenced sedimentary structures. A microbial fossil

Does one on one tutoring have a positive effect on my students' Dissertation

Does one on one tutoring have a positive effect on my students' attitude about reading - Dissertation Example Furthermore, studies showed a strong relationship between structured and quality tutoring and reading attitudes. Sources indicated, however, that contextual factors must also be considered when understanding attitudes on reading, such as training of tutors and structure of tutor strategies, frequency and regularity of tutoring sessions, close monitoring and evaluation practices, and specially designed curriculum for readers with reading problems or disabilities (McKenna et al., 1995; McKool, 2007; National Institute on Out-of-School Time at Wellesley Centers for Women, 2009; U.S. Department of Education, 1997). Does one-on-one tutoring have a positive effect on students' attitude about reading? I am directly involved in tutoring students to improve their attitude about reading. I am currently tutoring a 4th grader with ADHD, who reads at about a beginning 3rd grade level with poor comprehension skills. This boy has 3 siblings (1 older brother and 2 younger sisters) and a loud, rather disorganized home. The research will also include a 3rd grader who a co-worker is tutoring. This student has a stutter and reads at about a mid 1st grade level with difficulties in vowel sounds. This boy is an only child and I do not have knowledge of his home life or condition. Both boys have parents that are supportive, but only the 3rd grader’s mom is very involved with helping her child. ... This paper reviews the literature on tutoring and reading. Review of Literature The review of literature reveals that are numerous factors that shape reading attitudes, but the most prevalent are children's personal experiences in reading, children's self-confidence in reading, parents' attitudes towards reading, and teachers' teaching strategies. Furthermore, studies showed a strong link between structured and quality tutoring and reading attitudes. Factors that can Shape Reading Attitudes There are a variety of factors that affect children's attitudes toward reading: children's personal experiences in reading, children's self-confidence in reading, parents' attitudes towards reading, and teachers' teaching strategies. Sources indicated, however, that contextual factors must also be considered, such as training of tutors and structure of tutor strategies, frequent and regular tutoring sessions, close monitoring and evaluation, and specially designed curriculum for readers with readi ng problems or disabilities (McKenna et al., 1995; McKool, 2007; National Institute on Out-of-School Time at Wellesley Centers for Women, 2009; U.S. Department of Education, 1997). Children’s personal experiences in reading. Children's personal experiences in reading can improve children's attitudes toward reading (Wang, 2000, p.1). It is important that the environment of the children provides easy access to interesting books, because this leads to them experiencing the world of reading as an entertaining experience (National Institute on Out-of-School Time at Wellesley Centers for Women, 2009; Wang, 2000, p.1). Access to quality books, however, is not widely provided by low-income families.
