Thisplan might involve handouts, lessons, and special written instructions to help students in thisexperimental group learn how to study a subject using computers. Design a plan for procedures for an experimental study. 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. According to Smith et al., (1979), quantitative research employs the traditional, the positivist, the experimental, or the empiricist method to enquire into an identified problem. Thecollection procedures in qualitative research involve four basic types and their strengths andlimitations, as shown in Table 9.2. ^d)bD]qiN0#IbGd5~m (m$$z9YY+N&1, Nestor Asiamah, Henry Kofi Mensah, and Eric Fosu Oteng-Abayie, General, Target, and Accessible Population: Demystifying the Concepts for Effective Sampling. Guest and colleagues (2012)discussed and illustrated the use of codebooks in qualitative research. A table with numbers and percentages describing respondents and nonrespondents is auseful tool to present this information. The dropout rate the previous year was 25%. If audiotaping is used, researchers need to planin advance for the transcription of the tape. Researchersplot each data point separately on the graph, and connect the data points with lines (e.g., see Neuman& McCormick, 1995). There are those involving participants (i.e., history, maturation, regression,selection, and mortality), those related to the use of an experimental treatment that the researchermanipulates (i.e., diffusion, compensatory and resentful demoralization, and compensatory rivalry),and those involving procedures used in the experiment (i.e., testing and instruments).Table 8.5 Types of Threats to Internal ValidityType of Threat to Description of Threat In Response, Actions the Researcher Can TakeInternal ValidityHistory Because time passes during an experiment, events The researcher can have both the experimental and can occur that unduly influence the outcome beyond control groups experience the same external events. Because text and image data are so dense and rich, not all of the information can be used in aqualitative study. 321322).Methodology The site of this study was a small (enrollment 1,000), religious, coeducational, liberal arts college in a Midwestern city with a population of 175,000 people. A log kept by the researchers would work equally well for this form of data.Data Analysis and Interpretation A methods discussion in a qualitative proposal needs also to specify the steps in analyzing thevarious forms of qualitative data. 1 Steps for addressingthese potential issues are also presented in Table 8.6. In Table 8.3, I show how the factors, in combination, lead to the selection of a number ofcommon statistical tests. Chapter 1 opens with -- definition of research approaches and the . 2. This form of validity is different than identifying the threats tovalidity in experimental research, as discussed later in this chapter. Indicate the major content sections in the instrument, such as the cover letter (Dillman, 2007,provides a useful list of items to include in cover letters), the items (e.g., demographics, attitudinalitems, behavioral items, factual items), and the closing instructions. endobj According to Creswell (2014), phenomenology research typically ranges from three to ten participants (p. 189). 2. First of all, there is no specific answer to this question; although I have taken the position(Creswell, 2013) that sample size depends on the qualitative design being used (e.g., ethnography,case study). 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). 5 0 obj Focus should also be on whether or not the researchquestions/hypotheses were supported.Example 8.1 A Survey Method SectionAn example follows of a survey method section that illustrates many of the steps just mentioned.This excerpt (used with permission) comes from a journal article reporting a study of factorsaffecting student attrition in one small liberal arts college (Bean & Creswell, 1980, pp. The interview protocol needs to include the followingcomponents: A heading (date, place, interviewer, interviewee) Instructions for the interviewer to follow so that standard procedures are used from one interview to another The questions (typically an ice-breaker question at the beginning followed by four to five questions that are often the subquestions in a qualitative research plan, followed by some concluding statement or a question, such as, Who should I visit with to learn more about my questions? Probes for the four to five questions, to follow up and ask individuals to explain their ideas in more detail, or to elaborate on what they have said Spaces between the questions to record responses A final thank-you statement to acknowledge the time the interviewee spent during the interview Researchers typically develop a log to keep a record of documents collected for analysis in a qualitative study. The fact that individuals were reminded of past traumatic incidentsretriggering prompted us to use the term as an important code and ultimately a theme in our analysis. This calculation involves thefollowing: A consideration of the level of statistical significance for the experiment, or alpha The amount of power desired in a studytypically presented as high, medium, or lowfor the statistical test of the null hypothesis with sample data when the null hypothesis is, in fact, false The effect size, the expected differences in the means between the control and experimental groups expressed in standard deviation units Researchers set values for these three factors (e.g., alpha = 0.05, power = 0.80, and effect size =0.50) and can look up in a table the size needed for each group (see Cohen, 1977; Lipsey, 1990). How was it operationalized?_____________ Will variables be covaried in the experiment? endobj and writes the final report that includes. Total Population Sampling . 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. 6 0 obj Sampling is a way that you can choose a smaller group of your population to research and then generalize the results of this across the larger population. 3.2. This descriptive methodology focuses more on the "what" of the research subject than the "why" of the research subject. Specify the form of data collection. Research Design Fifth Edition. It could also be a meaning derived from a comparison of the findings with informationgleaned from the literature or theories. ]Multiple regression and path analysis (Heise, 1969; Kerlinger & Pedhazur, 1973) were used toanalyze the data. <>stream Itinvolves segmenting and taking apart the data (like Peeling back the layers of an onion) as well asputting it back together. In a proposal for a study, it is helpful to note in this log whether the information represents primary material (i.e., information directly from the people or situation under study) or secondary material (i.e., secondhand accounts of the people or situation written by others). For experimental research, investigators use a power analysis(Lipsey, 1990) to identify the appropriate sample size for groups. endobj They may use a protocolan instrument for collecting databut the researchers are the ones who actually gather the information. A helpful conceptualization to advance in the methods section is that qualitative data analysiswill proceed on two levels: (a) the first is the more general procedure in analyzing the data (seebelow), and (b) the second would be the analysis steps embedded within specific qualitative designs.For example, narrative research employs restorying the participants stories using structural devices,such as plot, setting, activities, climax, and denouement (Clandinin & Connelly, 2000).Phenomenological research uses the analysis of significant statements, the generation of meaningunits, and the development of what Moustakas (1994) called an essence description. There are several ways that you can sample. It is important to gain access to research or archival sitesby seeking the approval of gatekeepers, individuals at the site who provide access to the site andallow or permit the research to be done. The book explores statistical power and includes a table tohelp researchers identify the appropriate size of groups in an experiment.Neuman, S. B., & McCormick, S. Reliability of thefactors was established through the coefficient alpha. Creswell is currently growing at a rate of 1.06% annually and its population has increased by 3.24% since the most recent census, which recorded a population of 5,641 in 2020. 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.

Researchers send this fourth mail-out 3 weeks after the second mail-out. <> ), Handbook of research on teaching (pp. Further, because the writing structure of a qualitative project mayvary considerably from study to study, the methods section should also include comments about thenature of the final written product. 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. What activities will occur at the site during the research study? Report information about the number of members of the sample who did and did not returnthe survey. Forexample, in a repeated measures design, participants are assigned to different treatments at differenttimes during the experiment. Population in this study was the twelfth graders of a Senior High School in Bandung where the researcher did teaching practicum. 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. In other words, a purposive sample is collected according to the requirements of the test, survey, or research that it'll be used for. This call for descriptive analysis is consistent with the recentAPA Publication Manual (APA, 2010). A single-stage sampling procedure is one inwhich the researcher has access to names in the population and can sample the people (or otherelements) directly. Instead, he recommended that sample sizedetermination relates to the analysis plan for a study. and Creswell, J.D. 421 0 obj In this article, we begin with the fundamental building block of any population: the unit of analysis. No horizontal line between the groups displays random assignment of individuals to treatment groups. Newark, DE: International Reading Association. These interviews involve unstructured and generally open-ended questions that arefew in number and intended to elicit views and opinions from the participants. [Authors presented descriptive information about thesample. In a study of leadership in nonprofit organizations, I might learn about the impact of geo-warming on the building of the organization and how this shapes the location and proximity of individuals to one another. In the design of anexperiment, the researcher identifies participants in the study, the variablesthe treatment conditionsand the outcome variablesand the instruments used for pretests and posttests and the materials to beused in the treatments. Administer measures of the dependent variable or a variable closely correlated with the dependent variable to the research participants. This questionnaire had been developed and tested at three other institutionsbefore its use at this college.

For example,researchers match participants in terms of a certain trait or characteristic and then assign oneindividual from each matched set to each group. Description. Bogdan and Biklen (1992) advanced topics that could be addressed insuch a proposal: Why was the site chosen for study? A research can use a wide range of methods for data collection, such as case study, observational, and survey methods. Writing a methodssection for a proposal for qualitative research partly requires educating readers as to the intent ofqualitative research, mentioning specific designs, carefully reflecting on the role the researcher playsin the study, drawing from an ever-expanding list of types of data sources, using specific protocolsfor recording data, analyzing the information through multiple steps of analysis, and mentioningapproaches for documenting the accuracyor validityof the data collected.

Third, estimate the percentage of your sample that will respond in a givenway (50% with 50/50 being the most conservative because people could respond either way). Thus, interpretation in qualitative research cantake many forms; be adapted for different types of designs; and be flexible to convey personal,research-based, and action meanings. 16 0 obj For example, a factorial design experiment, a variation on the between-group design, involves using two or more treatment variables to examine the independent andsimultaneous effects of these treatment variables on an outcome (Vogt, 2011). Design and analysis: A researchers handbook (4th ed.). Cluster sampling is ideal when it is impossible or impractical to compile a list of theelements composing the population (Babbie, 2007). 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). It is broader than the concept sample frame. Also mention reliability checks forthe internal consistency of the scales (i.e., the Cronbach alpha statistic). 8. Mark. For a mailed survey, identify steps for administering the survey and for following up to ensure ahigh response rate. During the process of research, the investigator may collect qualitative documents. <> drawing on personal reflections and past. personal biases and a flexible structure. Another definition comes from Creswell (2012) who notes that population is a group of individuals who have the same characteristics. the total of particles at a particular energy level. Researchers can select participants by random selection or random sampling.

Information and translations of Creswell in the most comprehensive dictionary definitions resource on the web. Many designs exist, such as the 28approaches identified by Tesch (1990), the 22 types in Wolcotts (2009) tree, and the five traditionsto qualitative inquiry by Creswell (2013). In a true experiment, the investigator randomly assigns the participants to treatmentgroups.

Perhaps jot down some ideas as they come to mind as you read. design, population and sample, research instrument, procedure, and data analysis. Make a final decision on the abbreviation for each category and alphabetize these codes. endobj In qualitative research, theimpact of this process is to aggregate data into a small number of themes, something like five to seventhemes (Creswell, 2013). Will they be matched? Thisoften leads to compromises in the researchers ability to disclose information and raises issues of animbalance of power between the inquirers and the participants. The software program then can generate results and report them back to theresearcher as descriptive statistics or as graphed information. Participants meanings: In the entire qualitative research process, the researcher keeps a focuson learning the meaning that the participants hold about the problem or issue, not the meaningthat the researchers bring to the research or that writers express in the literature.Emergent design: The research process for qualitative researchers is emergent. After the treatment, the researcherselects a comparison group and provides a posttest to both the experimental group(s) and thecomparison group(s).Group A X ________________ OGroup B ________________ OAlternative Treatment Posttest-Only With Nonequivalent Groups DesignThis design uses the same procedure as the Static Group Comparison, with the exception that thenonequivalent comparison group received a different treatment.Group A X1 ________________ OGroup B X2 ________________ OExample 8.3 Quasi-Experimental DesignsNonequivalent (Pretest and Posttest) Control-Group DesignIn this design, a popular approach to quasi-experiments, the experimental Group A and the controlGroup B are selected without random assignment.

Now these discussions are less frequentlyfound in the literature and there is some consensus as to what constitutes qualitative inquiry. [1] expectations of the control group. Practical research tips for proposal writers to address validity issues are as follows: Identify the potential threats to validity that may arise in your study. How?_____________ How many participants will be in the experimental and control group(s)?_____________ What is the dependent variable or variables (i.e., outcome variable) in the study? Intervening variables significantly related to intent to leavewere then regressed on organizational variables, personal variables, environmental variables,and background variables. Assemble the data material belonging to each category in one place and perform a preliminary analysis. Tavallaei and Talib (2010) further note that qualitative approaches are utilized "when the researcher's variables are unclear and unknown and when a relevant theory base is missing in any sense" (p. 571). Using products such as these, researchers cancreate their own surveys quickly using custom templates and post them on websites or e-mail them forparticipants to complete. Thus, mysuggestions about this section of a proposal are as follows: Review the needs of potential audiences for the proposal. Single-subject experimental research: Applications for literacy. 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. data. The median on the final sample was checked and a few participants recategorized by the final median split, which resulted in 12 or 13 participants per cell. US English. New York: The Guilford. Insome survey projects, the researcher assembles an instrument from components of severalinstruments. From sample results, the researcher generalizes ordraws inferences to the population.

The total population of the tenth grade students in Office Management major is 107 students from three classes. Do results correlate with other results? 3.2.1 Population According to Creswell (2012, p. 142), population is a group of individuals who have the same characteristics. Experimental researchersneed to identify potential threats to the internal validity of their experiments and design them so thatthese threats will not likely arise or are minimized. In these field notes, the researcher records, in an unstructured or semistructured way (using some prior questions that the inquirer wants to know), activities at the research site.
