Indicate the number of people who will test the instrument and the plansto incorporate their comments into final instrument revisions. endobj These designs focus on datacollection, analysis, and writing, but they originate out of disciplines and flow throughout the processof research (e.g., types of problems, ethical issues of importance). Gather field notes by conducting an observation as an observer. These involve telling the reader about the design being usedin the study and, in this case, the use of qualitative research and its basic intent. Thecollection procedures in qualitative research involve four basic types and their strengths andlimitations, as shown in Table 9.2. endobj Shim, Chin Yee Chan, Si Yee Wei, Yuan Ghani, Hazim Ahmad, Liyana Sharif, Hanisah Alikhan, Mohammad Fathi Haji Bagol, Saifuddien Taib, Surita Tan, Chee Wah Ong, Xin Mei Wang, Lin-Fa Wang, Yan Liu, An Qi Lim, Hong Shen Wong, Justin Naing, Lin and Cunningham, Anne Catherine 2022. In contrast to other designs, thequalitative approach includes comments by the researcher about their role, and the specific type ofqualitative strategy being used. which the inquirer: analyzes and codes the data for description. endobj In preparing to design these components into a proposal, consider thequestions on the checklist shown in Table 8.1 as a general guide.Table 8.1 A Checklist of Questions for Designing a Survey Method_____________ Is the purpose of a survey design stated?_____________ Are the reasons for choosing the design mentioned?_____________ Is the nature of the survey (cross-sectional vs. longitudinal) identified?_____________ Is the population and its size mentioned?_____________ Will the population be stratified? How will they be addressed?_____________ Will a pilot test of the experiment be conducted?_____________ What statistics will be used to analyze the data (e.g., descriptive and inferential)?_____________ How will the results be interpreted?Participants Readers need to know about the selection, assignment, and number of participants who will takepart in the experiment. (Eds.). These interviews involve unstructured and generally open-ended questions that arefew in number and intended to elicit views and opinions from the participants. Thus, the total number of population was 49 students. Creswell (2013) notes that qualitative research methods typically aid in researching topics where little is known about a phenomenon. The key characteristics of survey research stated by Creswell (2012) are "sampling from a population, collecting data through questionnaires and interviews, designing instruments for data collection, and obtaining a high response rate" (pp. In other words, a purposive sample is collected according to the requirements of the test, survey, or research that it'll be used for. 12 0 obj Here are essential aspects of the population andsample to describe in a research plan: Identify the population in the study. New York: The Guilford. Thus, mysuggestions about this section of a proposal are as follows: Review the needs of potential audiences for the proposal. Thisanalysis is useful in designing detailed descriptions for case studies, ethnographies, and narrativeresearch projects. application/pdf The third mail-out consists of a postcard follow-up sent to allmembers of the sample 4 to 8 days after the initial questionnaire. The first two programs weredeveloped in Germany and the third in Australia. Guest and colleagues (2012)discussed and illustrated the use of codebooks in qualitative research. Human populations . 7. Researcher as key instrument: Qualitative researchers collect data themselves through examining documents, observing behavior, or interviewing participants. In qualitative research, theimpact of this process is to aggregate data into a small number of themes, something like five to seventhemes (Creswell, 2013). One group, for example,may participate in a special computer-assisted learning plan used by a teacher in a classroom. One or more groups receive theexperimental manipulation, or treatment, from the researcher. 2. A standardnotation system needs to be used in this figure. As with any softwareprogram, qualitative software programs require time and skill to learn and employ effectively,although books for learning the programs are widely available. ]COMPONENTS OF AN EXPERIMENTAL METHOD PLANAn experimental method discussion follows a standard form: (a) participants, (b) materials, (c)procedures, and (d) measures.

Its basic premise is that an experiment needs to have sufficient sensitivity to detectthose effects it purports to investigate. The following are a few advantages of using a descriptive research design: 1. Mia.

[Authors presented descriptive information about thesample. An interpretation in quantitative research means that the researcherdraws conclusions from the results for the research questions, hypotheses, and the larger meaning ofthe results. This is an essentialchapter for students beginning their study of experimental studies.Fowler, F. J. This discussion can do the following: Identify the purpose of survey research. Natural setting: Qualitative researchers tend to collect data in the field at the site where participants experience the issue or problem under study. Marshall and Rossman (2011) discussed five typescommon across five different authors. Although the processes are similar, qualitative methods rely on text and image data, have unique steps in data analysis, and draw on diverse designs. Separation of parallel rows by a horizontal line indicates that comparison groups are not equal (or equated) by random assignment. Floyd Fowler provides a useful text about the decisions that go into the design of a survey researchproject. Hand coding is a laborious and time-consuming process, even for data from a few individuals. Other threats that might be mentioned in the method section are the threats to statistical conclusionvalidity that arise when experimenters draw inaccurate inferences from the data because ofinadequate statistical power or the violation of statistical assumptions. 3 0 obj ]Data were collected by means of a questionnaire containing 116 items. There are three kinds of survey media that used in survey research, that are written survey, verbal survey and mix mode survey. Interested in flipbooks about John W.

Both groups take a pretest and posttest. Philosophical assumptions to consider: Ontological - what is the nature of reality (Reality is multiplex) Epistemological - what is the nature and definition of knowledge? Writing Exercises 1. Fowler (2009) identified the following types: mail,telephone, the Internet, personal interviews, or group administration (see also Fink, 2012; Krueger &Casey, 2009). For example, suppose that a study is going to conduct a survey of high school students on their . An overall guide to these topics is found by answeringthe questions on the checklist shown in Table 8.4.Table 8.4 A Checklist of Questions for Designing an Experimental Procedure_____________ Who are the participants in the study?_____________ What is the population to which the results of the participants will be generalized?_____________ How were the participants selected? Descriptive research definition: Descriptive research is defined as a research method that describes the characteristics of the population or phenomenon studied. A statistical test isconsidered to be significant if the results are unlikely by chance to have occurred, and the nullhypothesis of no effect can be rejected. endobj Also, in large databases, the researcher can quickly locate allpassages (or text segments) coded the same and determine whether participants are responding to acode idea in similar or different ways. 4. Suggest why or why not theresults were significant, drawing on past literature that you reviewed (Chapter 2), the theory used inthe study (Chapter 3), or persuasive logic that might explain the results. <> While interviews aregoing on, for example, researchers may be analyzing an interview collected earlier, writing memosthat may ultimately be included as a narrative in the final report, and organizing the structure of thefinal report. Collect cell phone text messages (e.g., Twitter). Discuss a plan to provide a descriptive analysis of data for all independent and dependentvariables in the study. Assuming that you proceed beyond descriptive approaches, if the proposal contains aninstrument with scales or a plan to develop scales (combining items into scales), identify thestatistical procedure (i.e., factor analysis) for accomplishing this. To explain it better: This willrequire drawing inferences and conclusions from the results. and test-retest correlations (Are scores stable over time when the instrument isadministered a second time?). Gibbs et al (20 07) and Patton (2002) demonstrated that there were a number of methods the research ers would . A visual modelof many facets of a process or a central phenomenon aids in establishing this holistic picture(see, for example, Creswell & Brown, 1992).Qualitative Designs Beyond these general characteristics are more specific designs. Still other independent variables can be statistically controlled, suchas demographics (e.g., gender or age). Qualitative observers may also engage in roles varying from a nonparticipant to a complete participant. The left-to-right dimension indicates the temporal order of procedures in the experiment (sometimes indicated with an arrow). With randomselection or random sampling, each individual has an equal probability of being selected from thepopulation, ensuring that the sample will be representative of the population (Keppel & Wickens,2003). Design and Experimental Manipulation This study used a 3 2 2 factorial design: Orientation of Counselor (nonsexist-humanistic, liberal feminist, or radical feminist) Statement of Values (implicit or explicit) Participants Identification with Feminism (feminist or nonfeminist). Quantitative is based on testing a theory, measured with numbers, Then deductively, the researchers look back at their data from the themes to determine if more evidence can support each theme or whether they need to gather additional information. This inductive process illustrates working back and forth between the themes and the database until the researchers have established a comprehensive set of themes. Creswell's definition of Qualitative Research: Qualitative research is an inquiry process of understanding based on distinct methodological traditions of inquiry that explore a social or human problem. What would a visual model of this design look like?_____________ What instrument(s) will be used to measure the outcome in the study? Most of the surveys mentioned above seek to monitor trends over time. 420 0 obj Population in this study was the twelfth graders of a Senior High School in Bandung where the researcher did teaching practicum. Include statements about past experiences with the research problem or with the participants orsetting that help the reader understand the connection between the researchers and the study. If you present the basic characteristics, what ones should you mention? Who developed it? Asking, What were the lessons learned? captures the essence of this idea(Lincoln & Guba, 1985). Then the researchers review all of the data, make sense of it, and organize it into categories or themes that cut across all of the data sources. The baseline behavioris assessed, the treatment provided, and then the treatment is withdrawn. For visual data, asketchbook of ideas can begin to take shape. Pretests and treatments are varied for the four groups. Using Fowlers (2009) table, forexample, with a margin of error of +/4%, a confidence error of 95%, and a 50/50 chance that thesample contains our characteristic, we arrive at a sample size of 500.Instrumentation As part of rigorous data collection, the proposal developer also provides detailed informationabout the actual survey instrument to be used in the proposed study. He addresses use of alternative sampling procedures, ways of reducing nonresponse rates,data collection, design of good questions, employing sound interviewing techniques, preparation ofsurveys for analysis, and ethical issues in survey designs.Keppel, G. & Wickens, T. D. (2003). For single-subject research designs, use line graphs for baseline and treatment observations forabscissa (horizontal axis) units of time and the ordinate (vertical axis) target behavior. Scores, over time, experiment. 64 0 obj One further issue about coding is whether the researcher should (a) develop codes only on thebasis of the emerging information collected from participants, (b) use predetermined codes and thenfit the data to them, or (c) use some combination of emerging and predetermined codes. Mention theprocedures used to check for response bias, such as wave analysis or a respondent/nonrespondentanalysis. This call for descriptive analysis is consistent with the recentAPA Publication Manual (APA, 2010). Step 5. Client statements and the outcome of each interview were held constant, whereas counselor responses differed by approach. Another definition comes from Creswell (2012) who notes that population is a group of individuals who have the same characteristics. Creswell (2002) noted that quantitative research is the process of collecting, analyzing, interpreting, and writing the results of a study, while qualitative research is . In fact, research states that qualitative samples must be large enough to assure that most of all of the perceptions that might be important are revealed (Creswell, 2014; Turner, 2010). One approach is equating the groups at the outset of the experimentso that participation in one group or the other does not influence the outcome. Information and translations of Creswell in the most comprehensive dictionary definitions resource on the web. In this situation, the process for maskinginformation requires discussion in the proposal.Data Collection Procedures Comments about the role of the researcher set the stage for discussion of issues involved incollecting data. To this end, Creswell . the total of individuals occupying an area or making up a whole. This codebook can evolve and change during astudy based on close analysis of the data when the researcher is not starting from an emerging codeperspective.

This means reporting efforts by authors to establish validity in quantitativeresearchwhether one can draw meaningful and useful inferences from scores on the instruments.The three traditional forms of validity to look for are (a) content validity (do the items measure thecontent they were intended to measure? The benefits of an experiment may be unequal or The researcher can provide benefits to both groups,Compensatory/Resentful resented when only the experimental group receives such as giving the control group the treatment after thedemoralization the treatment (e.g., experimental group receives experiment ends or giving the control group some therapy and the control group receives nothing). In specific, measurable terms, what is the population for whom you will hold yourself accountable to meet desired outcomes? Administer measures of the dependent variables to the experimental and control groups. 66 0 obj expectations of the control group. These themes are the ones that appear as majorfindings in qualitative studies and are often used as headings in the findings sections (or in thefindings section of a dissertation or thesis) of studies. J.W. A final category of qualitative data consists of qualitative audio and visual materials. & Higgins, 2001; Creswell, 2003) to explain the three types of population in relation to sampling. This descriptive methodology focuses more on the "what" of the research subject than the "why" of the research subject. Sample Arifin (2012:215) defines sample is the part of population to be Instead, Fowler (2009)suggested that these approaches are all misguided. Comment about sensitive ethical issues that may arise (see Chapter 3). 57 0 obj This kind of purposive sampling technique is commonly used to generate reviews of events or experiences, which is to say, it is common to studies of particular groups within larger .

Beyond identifying the themes during the coding process, qualitative researchers can do much withthemes to build additional layers of complex analysis. Indicate the type or types of data to be collected. Theseexperiences may involve participation in the setting, past educational or work experiences, or culture,ethnicity, race, SES, or other demographics that tie the researchers directly to the study. The target population is the subset of people for whom the program is designed, that you will actively recruit and retain, and for whom you will hold yourselves accountable for achieving outcomes. drawing on personal reflections and past. In an experiment, investigators may also identify a sample andgeneralize to a population; however, the basic intent of an experimental design is to test the impactof a treatment (or an intervention) on an outcome, controlling for all other factors that might influencethat outcome. definition of population by creswell In the following examples, this notation is used to illustrate pre-experimental, quasi-experimental,true experimental, and single-subject designs.Example 8.2 Pre-Experimental DesignsOne-Shot Case StudyThis design involves an exposure of a group to a treatment followed by a measure.Group A X ________________ OOne-Group Pretest-Posttest DesignThis design includes a pretest measure followed by a treatment and a posttest for a single group.Group A 01____________X____________02Static Group Comparison or Posttest-Only With Nonequivalent GroupsExperimenters use this design after implementing a treatment.

Backyard research (Glesne & Peshkin,1992) involves studying researchers own organization, or friends, or immediate work setting. For example, when studying a sensitive topic, it isnecessary to mask names of people, places, and activities. Table 8.5 displays these threats,provides a description of each one of them, and suggests potential responses by the researcher so thatthe threat may not occur. The purposive sampling method is about selecting samples from the overall sample size based on the judgment of the survey taker or researcher. In this case, the researchers might develop a qualitative codebook, a table that contains alist of predetermined codes that researchers use for coding the data. chapters published before receiving the doctorateDependent Variable 1: Grants Descriptive research Question 2: How See Questions 16, 17, and 18: grants from foundations,funded many grants has the faculty member federal grants, state grants received in the past 3 years?Control Variable 1: Tenure status Descriptive research Question 3: Is the See Question 19: tenured (yes/no) faculty member tenured?Relating the Independent Variable Inferential Question 4: Does prior See Questions 11,12,13,14,15 to Questions 16, 17, 181: Prior publications to the productivity influence the number of grantsDependent Variable: Grants received?fundedData Analysis and Interpretation In the proposal, present information about the steps involved in analyzing the data. In addition, gainingentry to a research site and the ethical issues that might arise are also elements of the researchersrole. When researchers collect data at theirown workplace (or when they are in a superior role to participants), the information may beconvenient and easy to collect, but it may not be accurate information and may jeopardize the roles ofthe researchers and the participants. The symbol R indicates random assignment. Decide whether audience members areknowledgeable enough about the characteristics of qualitative research that this section is notnecessary. Begin the discussion by reviewing the purpose of a surveyand the rationale for its selection for the proposed study. Another approach is equally viable. In this article, we begin with the fundamental building block of any population: the unit of analysis. Here are somesuggestions for developing ideas about variables in a proposal: Clearly identify the independent variables in the experiment (recall the discussion of variables inChapter 3). The target behavior of a singleindividual is established over time and is referred to as a baseline behavior. endobj 3.2.1 Quantitative Research Methodology Creswell (2013) defines quantitative research as: "A means of testing objective theories by examining the relationship among variables. Have a participant keep a journal or diary during the research study. Collect personal letters from participants. This analysis should indicate the means, standard deviations, and range ofscores for these variables. C = Confidence interval. Indicate the inferential statistical tests used to examine the hypotheses in the study. data for all the members of population. has been cited by the following article: TITLE: Motivational Strategies to Improve Artisan's Productivity in the Construction Industry in Ghana. Table 8.3 Criteria for Choosing Select Statistical Tests Report how the results answered the research question or hypothesis. Again, permission to use any part of other instruments needs to be obtained. A sample population is when a smaller group of a given population is formed. Figure 9.1 Data Analysis in Qualitative ResearchStep 1. Z = Z -Value. Analyze public documents (e.g., official memos, minutes, records, archival material). Also mention whether scores resulting from past use of the instrument demonstrate reliability.Look for whether authors report measures of internal consistency (Are the items responses consistentacross constructs?) <>351 0 R]/P 413 0 R/Pg 412 0 R/S/Link>> The most rigorous methodfor selecting the sample is to choose individuals using a random sampling, a topic discussed in manyintroductory statistics texts (e.g., Gravetter & Wallnau, 2009). This widely usedbehavioral research design explores the effects of each treatment separately and also the effects ofvariables used in combination, thereby providing a rich and revealing multidimensional view. The Definition. With these concerns in mind, inquirers explicitly identifyreflexively their biases, values, and personal background, such as gender, history, culture, andsocioeconomic status (SES) that shape their interpretations formed during a study. A researcher operationalizes a population by developing a specific list that closely approximates all the elements in the population. The median for the first half of the sample was then used to categorize the second half of the group as feminist or nonfeminist, and the remainder of the participants was randomly assigned to conditions separately from each feminist orientation group to ensure nearly equal cell sizes. The idea behindqualitative research is to purposefully select participants or sites (or documents or visual material)that will best help the researcher understand the problem and the research question. endstream Like this book? [Authors identified the overall design.] Recall that earlier in Chapter 4, in Examples 4.1 and 4.2, Iprovided an overview of the structure of a qualitative proposal that included these methodscomponents.The Characteristics of Qualitative Research For many years, proposal writers had to discuss the characteristics of qualitative research andconvince faculty and audiences as to their legitimacy. Describe the instrument or instruments participants complete in the experiment, typically filledout before the experiment begins and at its end. The introductory chapter presents an informative overview of thecomponents of experimental designs.Lipsey, M. W. (1990).
