The use of existing metrics and instruments could also be done as replication studies, particularly given the recent calls for more replication research related to educa-tional technology (e.g . Special education researchers conduct studies that can be considered replications. Replication helps verify that the presence of a behavior at one point in time is not due to chance.

The experiments set up in this replication study are consistent with their published registered report in eLife last year. This model of DNA replication is most widely accepted .

Replication study.

DNA Structure and Replication Study Guide Readings: Biology in Focus 3.6, 3.7, 13.1-13.4 LOs: 3G, 11 A-E Outline the discovery of DNA, reviewing the evidence that supports the double helix model. We add a few words on the opposite of scientific discoveries, namely replication research.

Currently, few replication studies occur in the field of education (Makel & Plucker, 2014; Plucker & Makel, 2021) and specifically in educational technology where it has been noted that there is a "singular lack of replication studies" (Dron, 2021, p. 1). (1999). Nicky Terblanche, Joanna . Google Scholar; Ryland R . Both clear and practical, this groundbreaking volume covers how to introduce, develop, conduct, report, and discuss these studies, and the issues they raise for policy and practice. vif was found to be required for replication in the CD4+ T-cell lines CEM and H9 as well as in peripheral blood T lymphocytes. It is with replication that we start to trust a finding is likely real.

The DNA replication that occurs in all living cells is termed as semiconservative, meaning that the new DNA molecule will have one original strand (also called the parental strand) and one new strand of DNA.

Even better, when considering research, look for what is called a meta-analysis or a systematic review.

Please direct any questions or comments to replication@3ieimpact.org. By doing so, that prior research is confirmed as being both accurate and broadly applicable, since the replication study typically changes one or more variables of the original study, such as sample population, industry sector, etc. ABSTRACT.

Introduced in the 1980s by LaLonde (1986) and Fraker and Maynard (1987), design replication studies (also called "within-study comparison" designs) evaluate whether a quasi-experimental approach (such as an observational study, a comparative interrupted time series design, or a regression-discontinuity design) replicates findings from a gold-standard RCT with the same target population. Using this method, Lemons et al. The replication studies found an effect that did not exist in an earlier study. .

The description .

A replication study involves repeating a study using the same methods but with different subjects and experimenters. In design replication studies, treatment effects from a randomized experiment are compared to those obtained from a non-experimental .

Every time a study progresses to a new stage, 3ie updates this list. (2016) and Makel et al.

Replication studies in education are relatively rare. 10.3928/01484834-20141118-10. The Replication Programme has funded 23 replications through four rounds of funding. The field of psychology began to reckon with reproducibility around 2010 when a particularly dubious paper claimed to provide evidence of "precognition," or the ability to perceive events in the. The word "replication" has, of late, set many a psychologist's teeth on edge. 14. Replication studies help researchers verify the original results of the study.

(2016) reported that the rate of replication in special education is between 0.4 to 0.5%, meaning that out of all the articles published in our field, less than 1% are replications. First we make a distinction between replication and validation studies. There's more than one way to conduct a replication study: Beyond statistical significance.

This key text: brings together in a single volume, existing issues, claims and counterclaims, discourses, and practices of replication; introduces, covers, and extends this field of research, indicating its possibilities and limits; Both involve. Descriptors: Replication (Evaluation), Educational Research, Research Problems, Evidence Based Practice Routledge.

A replication study that validates existing research could, for example, improve the rating of a new law enforcement method from "promising" to "effective." The quest for reliability cannot mask the uncertainty inherent in all science. The operationalization of the variables, that is, the way variables are defined and manipulated, is not different in the replication of the original study.

Based on a literature review, it explains what replication studies are, and why they are important for our field.

In a replication study, the researcher repeats a study using the same methods but employs different variables such as different subjects and situations.

Upon completion of the replication study, contributors share statistics from the project necessary to complete meta-analyses (e.g., effect sizes).

New analysis finds that education researchers, unlike scholars in many other disciplines, don't check one another's work. The replication study was designed to examine whether the DAM shows discriminant validity compared to an existing measure, the Neutral Objects Satisfaction Questionnaire (NOSQ).

Replication Studies in Education Research?

In the "what works" agenda, the case for replication studies in education has strong proponents and supporting arguments. In most cases, replication is associated with duplication.In other words, you take a piece of published research and . So it is the "double check" of a study.

Close replications of (or failures to replicate) previous research are published online only in the Journal of Experimental Psychology: General and will be listed in the Table of Contents in the print journal. Contributors who complete all the CREP steps can earn small research awards (ranging from $300 to $500) sponsored by Psi Chi and the Center for Open Science. If the sample size of the replication study is 10 times larger (N = 80 and N = 800), the percentage of remaining false positive results in the meta-analysis shrinks to 10%. In the "what works" agenda, the case for replication studies in education has strong proponents and supporting arguments.

Often replication researchers begin a study motivated by questions of robustness and may even take for granted that a pure replication (which is applying the published analysis methods to . Stoet and Geary (2012) found that only 30% of later studies could replicate Spencer et al.'s (1999) finding of stereotype threat in females. In designing, conducting, and documenting the findings of studies in nursing education, researchers are encouraged to make design choices that improve study replicability and reproducibility of study findings. In this study, the effect of vif in the context of the HXB2 virus on virus replication in several CD4+ T-cell lines was investigated. 10. .

Hongmei Wang & Jiangtao Luo (2019). The goal of the replication study is to examine whether findings of Scruggs and colleagues replicate in a larger sample of students with high-incidence disabilities, which will provide important information regarding how these populations acquire and apply information. Exact replication serves to duplicate an original study's .

In systematic replication studies, a researcher introduces planned variation by relaxing one or more replication assumption while trying to meet all others.

Describe how isotopes were used to track DNA and/or proteins in the Hershey-Chase experiment and in the Meselson-Stahl experiment. 2012; Easley et al., 2000). 2.2.2 Replication Research. Based on a literature review, it explains what replication studies are, and why they are important for our field.

the original study) should always be informed about any replication attempt.

Exact (or close) replication: Such studies emphasize high fidelity replication of an earlier study, most possible in a controlled experimental laboratory setting. Some open discussions about replication . Thus, there is a need for the replication of research studies in education. In the approximate replication, King et al. A massive 8-year effort finds that much cancer research can't be replicated Unreliable preclinical studies could impede drug development later on An effort to replicate nearly 200 preclinical. We use the model to describe three types of publication biases: (1) file drawer bias, (2) a "repeat study" bias against the publication of replication studies, and (3) a "gotcha bias" where replication results that run contrary to a prior study are . The authors of the replicated study (i.e. Preparing a replication or update study in the business disciplines. vif was not required for replication in the SupT1, C8166, and Jurkat T-cell lines. A replication study in the proper sense means that one performs the same investigation, using the same experiments, materials, and tools as the original or . DNA replication occurs during the S phase of the cell cycle, illustrated below.This happens within the nucleus in eukaryotic cells.

The direction of an effect was found to change (i.e., a positive effect was found to be negative or vice versa).

It is possible to submit a proposal for a project that is not yet carried out, which, if sent out for external . We suspected thatfor a number of reasons (e.g., perceptions that replications are difficult to publish .

Providing an overview of key issues in theory and practice, Replication Research in Education is designed to identify and discuss the benefits and challenges facing replication studies in education. studies and contribute to the development of fundamental knowledge of ways to improve learning and other education outcomes.

Don't conduct measurement and estimation analysis (which some call robustness testing) before conducting a pure replication.

This paper presents a reflection on the importance of replication studies in the development of the field of mathematics education. Original studies that are suitable for replication testing contain statistically significant findings and effect sizes that are at least of a medium size.

One reason is publication bias. Replication is involves repeating the essence of an earlier research study with different subjects and in different circumstances.

For example, if 1 the population parameter value for the original study (study 1) and 2 is the population parameter for the replication study (study 2), then the magnatude of 1- 2 describes the degree to which study

Experience shows that replication studies that question the results of original studies are more likely to be published, and Gertler, Galiani, and Romero (2018) provide evidence from a survey of editors of economics journals showing that editors are much more likely to publish a replication study that overturns results than one that confirms results.

Analysis of the publication history of the top 100 education journals (based on their 5-year impact factor) showed that replication studies constituted only 0.13% of education articles (Makel .

Stoet and Geary (2012) conducted a similar analysis and found 23 studies that they classified as replications of a study of stereotype threat in females conducted by Spencer et al. European Journal of Scientific Research, 47, 278-287. replication studies, which are summed up by Polio and Gass (1997) as exact and conceptual replications.

(1982) changed the sampling procedures and modified the .

The replication studies replicated the previous findings, but also suggested that DAM and NOSQ are overlapping measures of the same construct. (See here and here. This paper outlines some of their key claims and argues that replication studies, whilst potentially making an important contribution to the "what works" and evidence-based agenda, and education more widely, face several challenges in the context-dense . . Once a study has been conducted, researchers might be interested in determining if the results .

Supported by the Institute of Education Sciences, the Collaboratory is working with experts in reading and special education to implement an iterative systematic replication evaluation of Read Well (RW1). Based on a literature review, it explains what replication studies are, and why they are important for our field. It also addresses the issue of why, despite their apparent importance, replication studies remain scarce.

. Replication is vital to psychology because studying human behavior is messy. This study is currently in progress. Explain how the Meselson-Stahl experiment demonstrates . This paper presents a reflection on the importance of replication studies in the development of the field of mathematics education. The replication study of " BET Bromodomain Inhibition as a Therapeutic Strategy to Target c-Myc " is proposed to replicate the key findings in the original paper published in Cell by Delmore et al.

Clearly, this definition requires some explanation. If a replication study is accepted for publication in IREE, the Editors will invite the original authors to comment the replication study. This paper outlines some of their key claims and argues that replication st. Route #1 Replication-based dissertations. For early-stage or exploratory research, proposals should explain how the reproducibility or replication study would contribute to the accumulation of knowledge regarding relationships The journal focuses on implementation and replication research that . ABSTRACT In the "what works" agenda, the case for replication studies in education has strong proponents and supporting arguments. Charlie Tyson. As Polio & Gass ( 1997) suggested a decade ago, faculty should play a role in changing the tide by discussing the importance of replication in graduate seminars and Ph.D. courses, and by encouraging students to read the existing literature carefully and to conduct replication studies. Subjects. Question: How feasible is it to procure funding and conduct replication studies in education research?

However, they do not often refer to them as replication studies. It is more likely to be a valid claim of newfound information when another confirms that one study's outcome is consistent. The replication study found a smaller effect than that found in the original study, and the difference was material.

In the "what works" agenda, the case for replication studies in education has strong proponents and supporting arguments. A replication study attempts to validate the findings of a prior piece of research. The Role of Replication Studies in Educational Research Jinfa Cai, Anne Morris, Charles Hohensee, Stephen Hwang, Victoria Robison, and James Hiebert This editorial discusses the critical idea of replication in educational research.

Instead of assessing replication evidence dichotomously, replication evidence should be assessed quantitatively. The majority of ecologists in our sample considered replication studies to be important (97%), not prevalent enough (91%), worth funding even given limited resources (61%), and suitable for publication in all journals (62%). This paper outlines some of their key claims and argues that replication studies, whilst potentially making an important contribution to the "what works" and evidence-based agenda, and education more widely, face several challenges in the context-dense, variable-rich field . It enables researchers to plan and conduct studies successfully, from their earliest stages through to completion. The main conclusion is that even replication studies with the same sample size as the original study have value and can help to reverse false positive findings. The replication study found a larger . Studies in the field of cognitive psychology had a higher replication rate (50%) than studies in the field of social psychology (25%).

This helps in determining whether the study can be generalized across locations, cultures, age groups, gender, etc.

Comparing artificial intelligence and human coaching goal attainment efficacy.

This paper presents a reflection on the importance of replication studies in the development of the field of mathematics education.

For example: a. Most quantitative dissertations, whether carried out by academics or undergraduate, master's or doctoral level students, will involve one of three types of replication, which we refer to as duplication, generalisation or extension.. It also addresses the issue of why, despite their apparent importance, replication studies remain scarce.

A replication study is a study that is an independent repetition of an earlier, published study, using sufficiently similar methods (along the appropriate dimensions) and conducted under sufficiently similar circumstances. In the meantime, the American Educational Research Association (AERA), which publishes a number of top education journals including Educational Researcher, decided last year (2013) to publish AERA Open as a new open-access research journal, and is specifically encouraging the publication of peer-reviewed replication studies in it. With so few replication studies, and many of those that are attempted producing null results, the scientific status of the evidence base for educational policy and practice is in question. Any contributor can take the lead in .

Both clear and practical, this groundbreaking volume covers how to introduce, develop, conduct, report, and discuss these studies, and the issues they raise for policy and practice.Bridging theory .

There are numerous extraneous variables that can result in bias if researchers are not vigilant. Advice / Support. Providing an overview of key issues in theory and practice, Replication Research in Education is designed to identify and discuss the benefits and challenges facing replication studies in education. This paper outlines some of their key claims and argues that replication studies, whilst potentially making an important contribution to the "what works" and evidence-based agenda, and education more widely, face several challenges in the context-dense .

When the authors took into account several characteristics of the studies replicated - such as the number of authors, the rate of male authors, the details of the experiment (location, language and online implementation) and the field in which the paper was published - the relationship between replicability and citations was unchanged. Journal of Development Effectiveness, 11(4), 373-390. Replication studies. Sort by: Recent Popular.

In the wake of high-profile controversies, psychologists are facing up to problems with replication.

If replication failure is observedand all other assumptions are metthen the researcher may infer that the assumption was violated and resulted in treatment effect heterogeneity. A lack of scientific transparency, however, should not be allowed to contribute to that uncertainty. It also addresses the issue of why, despite their apparent importance, replication studies remain scarce.

Replication studies had an annual mean of 7.3 citations, much higher than averages in linguistics and education.

REPLICATION RESEARCH IN NURSING 75 King and Tarsitano (1982) described an "approximate" replication of a study reported by Lindemann and Van Aernam (1971) which examined the effect of structured and unstructured preoperative teaching. Replication is a term referring to the repetition of a research study, generally with different situations and different subjects, to determine if the basic findings of the original study can be applied to other participants and circumstances. Getting serious about building nursing education science. For example, a laboratory study of the usability of a specific CPOE system could be repeated in a different laboratory by different investigators using the same protocol and system. Of the few which are conducted, many are conceptual rather than direct replications. The researchers will apply the existing theory to new situations in order to determine generalizability to different subjects, age groups, races, locations, cultures or any such variables. We track and maintain a list of all 3ie-funded and in-house replication studies, with details on the status of each.

The purpose of this article is to consider the potential benefits of conceptualizing special education intervention research within a framework of systematic, conceptual replication. Only research partners who are .

We offer a model of the publication process involving an initial study and a replication.

One of the most important ways researchers increase their trust in the validity of their findings is through replication. Book Description.

We estimated a mean rate of 1 published replication study for every 400 articles, with a mean of 6.64 years between initial and replication studies and a mean of 117 citations of the initial study before a replication was published. It just began . Implementation and Replication Studies in Mathematics Education is an important channel for academic work related to applying and scaling up the insights of mathematics education research, and a channel for bridging the academic community and the policy-making communities.

Indeed, for many important kinds of studies in mathematics education that involve the messy interactions among students, teachers, and mathematics in .

For a useful replication test, the original study needs to produce specific results and conclusions. Such a reply will be published along with the replication study.
