When estimating causal effects using observational data, it is desirable to replicate a randomized experiment E matching review closely as possible by obtaining treated and control groups with similar covariate distributions. This goal can often be achieved by choosing well-matched samples of the original treated and control groups, thereby reducing bias due to the covariates. Matching methods are gaining popularity in fields such as economics, epidemiology, medicine, and political science.

In an effort to increase science exposure for pre-college K—12 students and as part of the science education reform agenda, many biomedical research institutions have established university—community partnerships. Typically, these science outreach programs consist of pre-structured, generic exposure for students, with little community engagement. National Lab Network formerly National Lab Dayan ongoing initiative E matching review increase science equity and literacy, provides a model for engaging the public in science via an E-matching and hands-on learning approach.
We argue that science outreach should be a dynamic endeavor that changes according to the needs E matching review a target school. We will describe a case study of a tailored science outreach activity in which a public school that serves mostly under-represented minority students from disadvantaged backgrounds were E-matched with a university, and subsequently became equal partners in the development of the science outreach plan.
In addition, we will show how global science outreach endeavors may utilize a CBPA, like E-matching, to support a pipeline to science among under-represented minority students and students from disadvantaged backgrounds. By merging the CBPA concept with a practical case example, we hope to inform science outreach practices via the lens of a tailored E-matching approach. For that to become a reality I will have to take several steps in life, I know some of them but not all so E matching review would love for you to become my mentor and guide me through some of the necessary steps for my dreams to become my life in the future.
At times I wonder if I had the science classes that other students are getting if I would be interested in becoming part of the science field as I am now. Consequently, pre-college science outreach has grown to become an integral component of creating a generation of students that are scientifically literate and interested in pursuing science careers .
As reliance on the efforts of pre-college programs has increased, and such efforts to increase visibility and outreach of these programs have been expanded, the need to ensure that these programs meet the goals they have intended by targeting the specific concerns of the school community is more urgent than ever .
To address this need, we suggest that E-matching is a useful tool to ensure mutually beneficial partnerships between students and scientists. E-matching, a term coined in this paper, is electronic web-based matching of teachers and their students with science, technology, engineering, and mathematics STEM experts. The E-matching approach focuses on the needs of students both within and outside of the classroom, has the goal of increasing students' participation in science, and E matching review caters to pre-college science outreach needs.
Since science is a discipline that consists of multiple entry points and various subdisciplines, E-matching allows students to explore their specific interests by gaining access to mentors and experts within these specific domains. In addition, it helps harness their scientific interests by providing biomedical expertise that will be beneficial throughout their academic careers.

E-matching embraces the community-based participatory approach CBPAwhich has E matching review roots in the social sciences, public health, and education . The traditional science outreach programs typically involve a pre-structured science experience with little input from the teachers and students in the planning and implementation of the science outreach experience. However, applying the CBPA to E matching review outreach entails a collaborative approach that engages all partners and stakeholders equally.
In this project, stakeholders include high school science teachers, scientists, and science outreach administrators. Unlike the traditional approach, the CBPA acknowledges that each stakeholder has unique needs and contributes a unique strength to mutually benefit the partnership see Table 1.
The school benefits from a tailored science outreach experience and the scientists benefit from the stimulation of sharing research with inquisitive young minds and fulfilling broader impact objectives often required of grant submissions. This CBPA begins by assessing the primary interest of the school. E-matching allows a school to advertise its needs so that outside institutions that can provide resources may contact the schools and subsequently tailor an agenda to fulfill those needs.

This approach has many components that are deed to lead to more successful science outreach outcomes, as it 1 empowers the teacher with tools and resources to shape the science exposure needs of his or her students; 2 puts the needs of the school first; and E matching review facilitates a dynamic endeavor since each relationship is tailored to the needs of the school and the resources of the scientist. Table 1 describes the process of tailoring science outreach endeavors utilizing a CBPA via E-matching and compares it to the traditional approach to science outreach.
Recognizing a critical need to increase science equity and literacy, and employing a E matching review, NLN was created in as a national call to action. NLN tailors its outreach to the needs of the target student population via an E-matching service that links K—12 teachers with STEM professionals, organizations, and resources.
Scientists and teachers are matched on a variety of parameters including subject matter, geographic location, grade level, interests, need, and other factors Figure 1. This model allows for teachers to connect with STEM experts who can tailor an outreach based on the specific needs of teachers and students.
In addition to this linking process, all projects and registered users on the NLN website are accessible beyond suggested matches.
This process serves as a model that allows for a CBPA that complements a traditional one. Figure 2 shows archived from teachers on the NLN website. Websites have been used as a powerful tool for organizations to provide science outreach to E matching review public by providing online educational resources promoting hands-on learning  and virtual learning and building a community of scientists . The NLN model also complements existing efforts to create an online partnership between scientists and the public.
Most of the web-based resources complement each other by fulfilling different science outreach needs.
Ask a Biologist is a forum sponsored by Arizona State University where students can ask scientists questions about biology. This site also includes virtual experiments.
MySciNet allows scientists and students to discuss their general scientific interests and science careers. NLN enhances existing science web community efforts like these by directly linking students and teachers with experts who can provide both an E-learning experience and in-person, hands-on experiences within the classroom or at a collaborating institution.
This hands-on learning provides additional options for teachers and students to receive authentic scientific training in the real world. Employing the web for scientist—teacher—student matching has several advantages. First, the web platform provides a variety of resources that traditional matching services cannot deliver.
Scientists who represent institutions can choose student projects or schools that they want to work with. Second, the website provides personalization. Each teacher and scientist on the site has a personal dashboard and regular personal updates that are customized E matching review their goals and attributes. Third, teachers can either complement or fill a gap in their existing science curriculum with real world experiences from STEM experts.
Fourth, the website allows for community engagement via rapid connections between the K—12 school and the STEM professional. Finally, using the web provides data for measurement and assessment that can inform science outreach program practices Figure 1.
This Bronx high school's student body was largely made up of students who are of under-represented minority and from socioeconomically disadvantaged backgrounds. A teacher L. After discussions with the stakeholders, a tailored agenda was formulated addressing the K—12 school areas of interest E matching review 2.
In initiating the collaboration through a CBPA, both the K—12 school and the institution were bringing unique strengths to the endeavor. This approach also met the needs of all stakeholders in the partnership. The chances of my urban high school students interacting with science professionals increased dramatically with E-matching.

The ability to propose a project on the internet, which entailed the interaction of science professionals with urban youth, allowed for the publication of the needs of my chemistry and ecology class. In addition, the logistics of physical location, grade level appropriateness and diversity which were apparent within the proposal allowed for feasible responses. Communication is a key component in education and the ability to electronically connect with professionals actively engaged within the content area of study has important ramifications.
Students must work E matching review a rich, responsive environment and have contact with knowledgeable people in the community if they are to learn important critical thinking skills . Several institutions E matching review to my proposal, and engaged my students in ways that allowed for collaborations both within and outside the school setting [ Table 2 ]. As part of the outreach within the school setting, students targeted in my proposal listened to a presentation and interacted with a chemist from a translational research laboratory. As part of the out of school experience, students visited a biomedical research university The Rockefeller University.
Via personal testimonial, research presentation, science content demonstrations, interactive panel discussions, campus tours and meet and greet with a variety of researchers, students and professionals, students experienced the possibilities, activities and interactions which occur within a science educational research organization. Their knowledge base of the opportunities inherent within the scientific field and the connections between their understanding that what is learned in the classroom as an initiation to higher education settings and real E matching review application, broadened immensely.
The benefits and opportunities which resulted from the relationships formed during this E-matching process including acceptance of four students to the longer duration summer program enhanced the awareness of my Bronx high school students to the scientific community.
These connections were made possible due to the establishment of a venue in which partnerships could be initiated electronically. The fact that there were individual STEM professionals and their respective scientific organizations whom were willing and able to connect with urban youth and offer these students a window into the STEM community was made possible through the E-matching initiative.
As the teacher I also received stimulation from these opportunities to connect with scientific and educational professionals engaged in the process of academic and medical research. Such interactions will serve to enhance the educational experiences of the students, teachers and the scientific community.
Outreach via E-matching has shown several benefits. It has served as an information pipeline for under-represented minority and disadvantaged students, enabling them to consider science careers as a viable option.
Through establishment of an E-mentoring network the relationship has continued with the students who are interested in further discussions about science careers; this electronic E matching review network consists of Rockefeller University scientists, health professionals, staff, and research team members who have made their electronic contacts available for students to receive further guidance.
Lastly, under the auspices of NLN, this collaborative effort has allowed E matching review both institutional buy-in via funding for the initiative and community buy-in via navigating administrative logistics for a successful academic—community partnership.
Matching methods for causal inference: a review and a look forward
As a result of the community-based participatory E-matching approach, both the research institution and lay community had an equal investment in the outcome, because they are stakeholders at the beginning and are actively involved in formulating the agenda. This buy-in helps to E matching review long-term sustainability of the outreach. Utilizing E-matching and a CBPA to tailor science outreach allows for highly specific, targeted, and collaborative coordination of science outreach endeavors to meet the needs of all stakeholders. Reflecting back on the high school student's statement at the beginning of this manuscript about inequities in science access, E-matching can address some of the science exposure disparities seen in many urban classroom settings.
This approach may also serve as a pipeline to increase diversity in the STEM fields.
We don't deny that for some science outreach programs a traditional, pre-structured outreach may work better.
