Included in the study are the harmful substances produced by blue-green algae in algal blooms and noroviruses, the announcement said. Scientists "listen" to plants to find water pollution Scientists in Israel have discovered a new way to test for water pollution by "listening" to what the plants growing in water have to say. By shining a laser beam on the tiny pieces of algae floating in the water, the researchers said they hear sound waves that tell them the type and amount of contamination in the water.
Creswell and Amanda L. Educational researchers have propelled much of this forward progress and have developed novel methodologies to provide increasingly sound and complete evidence. Mixed methods research has emerged alongside quantitative and qualitative approaches as an important tool for researchers.
In this article our overall aim is to better acquaint educational scholars with the mixed methods field by articulating the development of the mixed methods field and by citing current trends and issues. The role of educational researchers in the evolution of mixed methods research is high- ligh ted.

T he c urre nt d ebate over key aspects of mixed methods research is now in progress and is ripe for future contributions. Even the very nature of what constitutes mixed methods research is being discussed among scholars. Understanding and advancing the mixed methods field is an important goal for methodologists and researchers.
With the inc rea se d intere st an d e n thu sia sm for m ixe d eswe writing a business eth od s re se arc h, it is likely that the dialogue surrounding mixed methods approaches will thrive, continuing the movement of the field.
These skills are needed to study the increa- singly complex problems facing educators and social scientists. Addressing these problems requires amassing substantial evidence — all types of evi- dence gained through measurement of precise questions, as well as more general assessment through open-ended questions.
In short, research approaches continually evolve and change in response to the com- plex, interconnected global communities and their needs in our world.
Quantitative research has traditionally provided a measurement orientation in which data can be gathered from many individuals and trends assessed across large geographic regions Creswell, On the other hand, qualitative research yields detailed information reported in the voices of participants and contextualized in the settings in which they provide experi- ences and the meanings of their experiences Creswell, When resear- chers bring together both quantitative and qualitative research, the strengths of both approaches are combined, leading, it can be assumed, to a better understanding of research problems than either approach alone.
Despite substantial developments in mixed me- thods, the field of study is plagued by early growing pains such as debates and disagreements about core issues such as its essential nature.
Lingering behind many thoughtful discussions about mixed methods are key stances of authors, many of which are not articulated clearly, and certainly not apparent to the casual reader of the mixed methods literature. A need exists to better understand the emerging nature of mixed methods and to clarify the stances of authors.
A need also exists to examine the literature closely to see whose voices are being heard or at least presented. Such an exploration in this article, it would seem, would help those decide if mixed methods is appropriate to use, assess whether it is a legitimate inquiry approach, and consider how to apply the approach to a particular study.
Purpose and concept clarification The purpose in this article is to briefly discuss the developments and trends of mixed methods that educators should be cognizant of and that educators have helped shape.
As a working definition, mixed methods is an approach to inquiry in which the researcher links, in some way e. A sub-text flowing throughout the discussion will be the important role that individuals in the field of education have played in the growth of mixed methods research.
Our focus on the role of educators is not to minimize the contributions of others and certainly others are mentioned ; our focus is only to create a dialogue about the educators involved in mixed methods during its year history.I shall not employ any subcontractor, whether verbal or in writing, unless properly licensed by Broward County or the State of Florida for any part or portion of the work.
