Characteristics of Experimental Research

Characteristics of observational Re lookup1) Hatties (2003) trigger officipants were classified as experienced or expert fit in to the issue Board for Professional Teaching Standards certification cognitive operation. This process is found on the best avail competent curtilage of what constitutes high standards of teaching and encyclopedism and has been rigorously searched and evaluated. On the boards website it saysAll of the look into contributes to intellectual and improving the content Board Certification process. Yet, it is mis take to draw major closing curtains approximately the boilersuit value and impact of guinea pig Board Certification based completely on individual studies. No hotshot line of business or diminutive group of studies bed effectively call the range of impact of the topic Board Certification process.(see http//www.nbpts.org/resources/ query/impact_of_certificationimpact)They stop short of saying that the explore proves that accreditati on improves the theatrical role of teaching and learning and this is in accord to with what Johnson and Christensen (2008) sayyou should pass off the word prove from your vocabulary when you be talking almost search? p22What does Johnson and Christensen (2008) mean and why be the NBPST so modest most their claims?On the contrary to the misunderstandings by small-army that a hypothesis stand be tested and proven to be true through interrogation, Johnson and Christensen (2008) asserts that inquiry is non a tool based on which a phenomena notify be proved to be true. It is a systematic process which acquires data of a relevant topic or an issue, analyses the data, interprets and reports affirmation. Research helps to understand a special(prenominal) assumption or a claim to be reasonable, unreasonable or assist to understand the reality. Johnson and Christensen (2008) chapters whiz, two and three helps to understand that there be two approaches to question qualitative and denary interrogation, which induct led to unalike orders of inquiry in recite to understand what is to be true or what constitute reality. Hatties (2003) enquiry indicates the importance of educational inquiry in understanding the important factors contributing to teaching and learning. However, as each educational reach differs from another, educators lease to be able to read and to interpret interrogation governings to their birth contexts to be able to suck in develop implications. According to Johnson and Christensen (2008), and McMillan (2004), educators also need to be able to question the quality of the research and take into fri sink noticeship the credibility of the research and the usefulness of the outcomes in making assured decisions almost teaching and learning in their own contexts.Johnson and Christensen (2008) point that better thought cannot be based on a single or footling sample research studies but multiple studies use change integrity methods research methods.Generalizing the research outcomes in to the educational settings inevitably to be based on the quality and the nature of study taken place, break officipants and the research methods used and examine other studies to see if there atomic number 18 any(prenominal) correlating destination on previous studies2) What is the nominate defining trait of experimental research? fibreicipating manipulation of an independent variable is the constitute defining characteristic of an experimental research.The characteristic of experimental research is where the researcher objectively observes a phenomena which is make to occur in a strictly controlled situation where one or to a greater extent than variables atomic number 18 systematically changed by manipulation.Active manipulation is not involved in any other pillowcasefaces of research. Because of this experimental research provides the strongest establish of all the research methods about the existe nce of cause and effect relationships (Johnson, Christensen 2008,p.41)3) A researcher discovered that assimilators who studied mathematics at University scored higher on a test of problem lick ability at the end of their degree than students who did not. The researcher argued that the study of mathematics should be encouraged because it improves a students ability to solve problems What type of design is this? Do you agree with the researchers conclusion? Give reasons.What type of design is this?Quantitative, causal-comparative research design.Do you agree with the researchers conclusion? Give reasons.Do not agree with the research conclusion.Johnson Christensen suggesrts that a surface design experimental research is virtually al focusings better for determine cause and effect than causal-comparative research or any other type of non experimental research(p.43). payable to the fact that non experimental research does not lease for manipulation of independent variables and we aker techniques of controlling outside(a) variables, cause and effect relationships atomic number 18 unable to be substantiated. Cause and effect is better explained in experimental research than in causal-comparative research (pp.43, 48).According to Johnson Christensen (2008.pp.43-48), and McMillan (2004. P194), there be propagation that causal-comparative research necessary to be conducted. The purpose of this research intended to be to investigate causal relationships when an experiment is not possible. However, the research needfully to contrive prior research evidence to substantiate or validate claims do by the research been conducted.Causal comparative research needs to manifest that all extraneous variables ar existence recognized and considered for an impartial conclusion. Due to the fact that the existing groups are used in the comparison, attention needs to be given to the possible differences in characteristics and other factors which might mildew the rese arch outcome. Causal comparative research often fails to lay down the exercises of extraneous variables on the research participants.4) Contrast the main characteristics of phenomenological and ethnographic approaches to research. Give an simile of how each approach could be applied to questions that are relevant to your oeuvrePhenomenological and ethnographical research approaches are two of five soft research methods and all of which share some common characteristics. Phenomenology understands the essence of experience. Phenomenological study focuses on how research participants experience certain phenomena. The researchers describe and interpret the experience of the participants in order to understand their own perspectives of the phenomenon. As Merleau-Ponty (1962) states, We can only very understand phenomenology by doing it there is a difference between comprehending phenomenology intellectually and understanding it from the inside (van Manen 1984). (Observation a compl ex research method.(Ethnological methods). http//find.galegroup.com.simsrad.net.ocs.mq.edu.au/Ethnographic research however, is not about individual perception or experience, its about a group perceptions, people or a cultural belonging or social norms. Ethnographic study intends to provide in-depth descriptions and identification of cultural norms or values such as attitudes, acts and norms among a group of people. The researchers include a holistic account in describing how a someone amaze a part of a group how they interact and how they station themselves as a group.Ethnography at the work place would identify how the team operates within the work environment the identicalness of the team common practices which would identify the characteristic of the team. Ethnography enables people to adapt or adopt to be part of the work environment to belong to the team. Phenomenology would identify how individuals operate and perceives situations, concepts and issues. It helps to analys e private experiences of distinct individuals. E.g. how one person experience or understands an issue or a concept might be different to another person. wherefore the experience and the interpretations are different.5) In his paper, Hattie (2003) draws upon a number of lines of evidence to surface that it is what teachers do that makes a difference to student outcomes, and he then reports on a study which attempts to presentation what expert teachers do. Firstly, he alludes to studies that employ graded Linear Modeling techniques which demonstrate that what teachers do has an important impact on student learning (see page 1). Next, he describes the results of a series of Meta Analyses which show that different the sorts of activities which teachers do have different effects on student learning (see page 3). Then, he reports on the results of a belles-lettres examine which identifies the characteristics of expert teachers (see page 5).Finally, he describes a study (see page 1 0) which demonstrates that these characteristics can in fact differentiate between expert and merely experienced teachers. In other words he has shown that these are meaningful characteristics and are therefore things that teachers should aspire to as they are markers of high standards of teaching and learning.The following(a) control panel shows the forms of data which Hattie (2003) used in his study to assess the 15 dimensions they used to distinguish expert from experienced teachers.Name the research look-alike he used in this study and describe its advantages. Which specific type of design did he employ ( enjoy give reasons for your choice?)The Research figure of speech Hattie (2003) uses is the Mixed methods research Design, a combination of Qualitative and Quantitative research methods. In his study, Hattie identifies meaningful characteristics and proposes a paradigm, a view that teachers should aspire to father expert teachers as opposed to becoming experienced in order to promote better outcomes for teaching and learning. He distinguishes the expert and the experienced teacher, and the influence they have on childrens learning outcomes. He arrived at these conclusions by using Mixed method research model in order to demonstrate credibility of his study and the research outcome. The research framework used by a researcher is important as it guides the research and it affects the research outcomes. The quality of a research depends on the methods of data collection, and the quality is influenced and enhanced by multiple methods of data collection. If only one method of research is used, the research findings might be influenced by the limitations of the techniques used and therefore considered as a weaker study and the limitations needs to be explained. Multiple methods allow for credibility and strengthens the research outcome therefore allows for a strong hypnotism of the study universe conducted. Johnson and Christensen 2004, (p.51) suggest us ing multiple perspectives and research methods in a single study strengthens the purpose of the study and provides clarity and credibility compared to a study used a single research methodology. Although different research methods have its own strengths and weaknesses, the researchers ability to use the mixed method design successfully prevents the research outcomes showing overlapping weaknesses. The fundamental process of mixed method research suggests it is wise to collect multiple sets of data using different research methods and approaches in such a way that the resulting mixture or combination has complementary strength and non overlapping weaknesses (p.51). As Johnson and Christensen suggest that an experimental research is able to better demonstrate origin but curb in realism due to the experimental setting that the research is universe conducted. Realism is well demonstrated in ethnographic studies where the researcher is able to observe participants in their natural set tings but limited in demonstrating causality compared to the experimental methodologies.As Hatties study consist of a variety of methods, it suggest a strong validity for his findings and therefore able to use it as an argument proposing that teacher needs to aspire to become experts in promoting better learning outcomes for children.6) find out the research topic(s), research problem(s), research purpose(s) and research question(s) in Brighton and Hertbergs (2004).Brighton, C., M.

What are teachers responses to the invitation to change their beliefs and practices to better address students academic diversity?2. What patterns of teachers responses to this invitation emerge?7) The director of a local Preschool wants to know whether children should begin the day with a ease up increase ceremony and the singing of the National hymn. Is this a researchable question as stated? Why or why not? If not , how might you neuter it to become one?Is this a researchable question as stated? NoWhy or why not? It is un estimableBest practice of educational research is to avoid questions which are sensitive to clean and honest principles and practices, and should not be subjected to empirical research for solutions.Flag and the National Anthem inform nationhood and identity of a country and a group of people. Therefore, suggesting whether the lurch should be embossed is unethical and unethical questions are inappropriate to be researched.Christenson and Johnson states these ideas typically involves making judgments of aesthetics, morality and religions(p.64).what is morally right, and proper and improper differs from one culture to another culture.The directors intention to raise the let up and to sing the national Anthem has potential to foster a whiz of cultural identity within the preschool community. One could question which flag will be raised? What is the dynamic of the presch ool setting? What is the contributing factor to initiate such a practice? Is the whole community represented with one flag? Is the flag representative of all cultures or a particular group? Is it expiry to foster unity or divide? What is the purpose of this suggestion? separate beliefs and practices are influenced by the cultural practices and the society that people are part of and these beliefs and values are instilled from an early(a) age. People are therefore sense and feel differently about issues and practices. Raising the flag and singing the National Anthem is culturally specific and the need to initiate such a ceremony needs to be clearly explained.Searching for ethics provided a valuable article which is worth mentioning, perhaps not directly relevant to the question being asked, yet provides an insight about humanity. Recent Russian history should have put to rest the view that anything is learned and man is infinitely malleable. After 75 years of cruel tyranny during which every effort was made to destroy civil society to create the clean Soviet Man, we learn that people kept civil society alive, if not well. The elemental building blocks of that society were not isolated individuals easily adroit to embrace any doctrine or adopt any habits they were families, friends, and refer groupings in which sentiments of sympathy, reciprocity, and fairness survived and struggled to shape behavior..Mankinds moral sense is not a strong beacon light, radiating outward to illuminate in sharp outline all that it touches. It is, rather, a small candle flame, moulding vague and multiple shadows, flickering and sputtering in the strong winds of cause and passion, greed and ideology. But brought close to the heart and cupped in ones hands, it dispels the darkness and warms the soul.The moral sense presidential address, American governmental Science Association, 1992.

Children will do this by being part of small groups and will have turns in raising the flag on different days.Please circle yes or no or feel free to write any comments as your inputs are valuable to ou r program.YesNoOther comments______________________________________8) How do valued and qualitative research questions differ in structure?In quantitative research, the questions are clearly and consciously articulated to communicate what will be studied. An important spirit of the question formulation is to convey the information about the variables which will be investigated. Knowing or understanding the variable is an important element in quantitative studies. An example of a quantitative question would be Do children from low socio economic families, who attend preschool programs five days a week develop fluent writing skills compared to who do not? In the quantitative studies, the question will specify or name the variables and often may explain how they may be related in single statements.Qualitative studies, like quantitative research involves looking at a everyday problem. However structuring of specific statements and questions differ greatly. Purpose and the logic of questions differ compared to quantitative questions. Qualitative questions are more open ended, general, and does not involves variables. As an example, What can preschool teachers do to enhance childrens literacy learning? In general, qualitative questions are more open ended and quantitative questions are close ended.(Johnson Christensen, McMillan 2004)9) An investigator wishes to identify the factors that predict persistence in problem solving tasks. In an coating to the Ethics committee he describes a study in which observations are made of preschool children who are given 5 minutes to solve a go. However, in reality the puzzle has no solution. What are the major ethical issues raised by this study and what procedures should the experimenter employ to comply with ethical standards?Child development and early child hood education and superintend literatures inform that childrens ability to complete tasks or to engage in problem solving experiences are guided by their environme nts, the adults around them, their moods, interests and many other factors of the times. A childs ability to persist cannot be measured by a 5 minutes observation with manipulating a puzzle. Childrens skills and abilities vary according to their developmental stages and the opportunities they have with learning experiences. Each child is unique in his or her developmental status. Perhaps the research could have focused on childrens ability to repress in tasks by providing a number of activities for children to choose from and by sight their attention with the chosen activity. Johnson and Christensen states many of the tests that are used with preschool children are referred to as screening tests rather than intelligence tests or academic achievement tests generally because the predictive validity of many of the preschool tests is weak (p160). Therefore, an achievement test of puzzle and problem solving is not appropriate for a preschool age group.Procedures that the experimenter needs to employ to comply with ethical standardsThe researcher needs to have informed consent from the participants, and in this case from parents or guardians, and given the purpose of the study, procedures, risks, benefits, preference procedures and limits of confidentiality.10) The purpose of this question is to start you thinking more deeply about an cranial orbit of practice that interests and to introduce you and your interests to the group. This will enable individuals with similar interests to find one other and begin working cooperatively designing studies in subsequent modules qualitative (Module 3), non-experimental quantitative (Module 4) and experimental studies (Module 5).
