Lijek2,3* 1Department of Biology, Oxford College of Emory University, Oxford, GA 30054, 2Department of Microbiology and Immunobiology, Harvard Medical School, Boston, MA 02115, 3The Journal of Emerging Investigators, www.emerginginvestigators.org Primary literature is the most reliable and direct source of scientific information, but most middle school and high school science is taught using secondary and tertiary sources. One reason for this is that primary science articles can be difficult to access and interpret for young students and for their teachers, who may lack exposure to this type of writing. The Journal of Emerging Investigators (JEI) was created to fill this gap and provide primary research articles that can be accessed and read by students and their teachers. JEI is a non-profit, online, open-access, peer-reviewed science journal dedicated to mentoring and publishing the scientific research of middle and high school students. JEI articles provide reliable scientific information that is written by students and therefore at a level that their peers can understand. For student-authors who publish in JEI, the review process and the interaction with scientists provide invaluable insight into the scientific process. Moreover, the resulting repository of free, student-written articles allows teachers to incorporate age-appropriate primary literature into the middle and high school science classroom. JEI articles can be used for teaching specific scientific content or for teaching the process of the scientific method itself. The critical thinking skills that students learn by engaging with the primary literature will be invaluable for the development of a scientifically-literate public. INTRODUCTION Students receive the majority of their scientific information and news from secondary and tertiary sources. In the science classroom, students typically learn from textbooks and sometimes popular science articles. Outside the classroom, students increasingly receive their science news from social media outlets such as Twitter, Facebook, and Reddit (10, 12). These crowdsourced platforms provide little to no objective, scientific review of the legitimacy of their content but instead prioritize information based on the “aggregated opinion of others” (11). In these settings, reports on scientific findings are often sensationalized because of the need to increase page views to generate advertising revenue. As the *Corresponding authors.

Not only do these misleading reports generate false beliefs, but they also misrepresent how scientific research is performed and evaluated (3, 6, 13). Students cannot be prevented from using these social media sources, and it would be just as difficult to convince those who share science-related information in these forums to critically evaluate the credibility of the information. One solution to this growing problem is to teach students to use the Internet to access and learn directly from the primary scientific literature, rather than from secondary or tertiary sources. This approach removes the layers of other people’s (mis)interpretation from students’ access to scientific information. Peer-reviewed primary literature provides evaluated scientific content, and reading the primary literature consequently strengthens student understanding of the scientific process (5, 8, 16). Moreover, engaging with primary scientific literature teaches students how to rigorously evaluate information from others and how to accurately communicate scientific information to others. Developing these skills in all students will be an important first step in creating a scientifically literate citizenry that is capable of critically evaluating any type of information. ©2016 Author(s).

Incorporating primary literature in the classroom can prove daunting, in part due to many articles’ narrow focus, their use of jargon, and sometimes their physical inaccessibility (14). Additionally, we cannot solely rely on schoolteachers to impart this education, since classroom time is often already stretched too thin and scientific communication and the research process can be unfamiliar subjects for teachers. One approach is to turn to scientists themselves to give students a better understanding of how the former perform hypothesisdriven research and effectively communicate their findings through peer-reviewed journal articles. To achieve this goal of promoting scientific literacy by connecting students with scientists, we formed the open-access, peer-reviewed Journal of Emerging Investigators ( JEI, www.emerginginvestigators.org). JEI is a free, online, non-profit science journal dedicated to engaging middle and high school students with primary scientific literature by having scientists mentor and evaluate students’ research for publication. JEI benefits students and teachers in two ways: 1) the peer-review and publication processes are educational experiences for the student-authors and their mentors, and 2) the resulting repository of student-written scientific articles serves as an age-appropriate, Internet-accessible tool for teaching any student how to read and interpret primary literature. As a completely free and online journal, JEI offers an alternative to Facebook or Twitter as a source for readily-accessible scientific information that is written by students, for students. At the same time, JEI maintains the structure and integrity of academic peer-reviewed science writing. and communication. In this way, student-authors are connected to scientists and gain valuable feedback on how to improve their scientific research and/or communication of their work. We believe that this peer-review process is the most important part of the educational experience for students, indeed as it is for professional scientists themselves. Since one of the main missions of JEI is to teach the scientific process through primary literature, it is imperative that each JEI article portrays the scientific method clearly. Therefore, JEI’s peer-review process places high value on how well the research question, hypothesis, and experimental approach are articulated. For example, each article is required to have a well-defined rationale that builds on previous scientific evidence. In addition, each article needs to describe clear experimental setups and controls, although we recognize that it may not be feasible 1 Scientific review as an educational experience JEI was started in 2012 and is still maintained by researchers at Harvard Medical School. The structure of the journal and its publication process are modeled on a typical academic journal, with three editors-in-chief who manage the publication process, a team of over 40 editors, who are each responsible for overseeing the publication of between one and four manuscripts per year, and over 75 expert scientific reviewers, many of whom are Ph.D. candidates or research fellows at the various research schools at Harvard University. The publication process is outlined in Figure 1 and is very similar to that of other academic journals. The first step in the process is for students to submit their research manuscript using the JEI website (www.emerginginvestigators.org), which also provides extensive guidelines for writing and submitting articles. Upon submission, the manuscript moves to the second step, in which the editor assigns three reviewers with expertise in the subject(s) of the article. The third, and critical, step is the peer-review, in which the scientists critique the manuscript and provide feedback on how to improve the research methodology, interpretation, FIGURE 1.  Outline of the JEI publication process. Students, along with their mentors (teacher, parent, or scientist), submit their original research manuscript through the JEI website. Editors select three scientists with expertise in the subject of the study to review the manuscript for scientific and written clarity. A manuscript will always require some changes or modifications prior to publication, and these changes may be minor communication changes or larger changes that require additional experimentation. Accepted papers are copy-edited and published on a rolling-basis on JEI’s website. There are no costs associated with JEI. Volume 17, Number 1 Journal of Microbiology & Biology Education 121 FANKHAUSER and LIJEK: PRIMARY LITERATURE IN THE CLASSROOM for some student-authors to perform all ideal controls. Student-scientists must also ensure that their experiments are safe, ethical, and comply with the International Rules for Pre-College Science Research (17), provided on JEI’s website. Finally, JEI asks students to write discussions that demonstrate deep thought about the implications of their work, even if the experimental parameters were not perfect and the results inconclusive. Different from other academic journals, JEI is aware that this review process is a learning experience for the student, and so reviewers are also instructed to provide encouraging remarks to the students to embolden them in their pursuit of science. In particular, reviewers are reminded that the manuscript was composed by young students and thus to adjust their expectations accordingly. JEI manuscripts do not have to examine a novel scientific question that has never been tested previously. Instead, JEI simply asks that student-authors propose scientific questions to which they themselves do not know the answer. JEI also acknowledges that students will have access to varying types of scientific equipment, and requires reviewers to evaluate the manuscript based on the quality of the scientific method and not the sophistication of the techniques. Overall, we have found that even the most unlikely submissions can be improved to publication quality, and only in dire cases such as breaches of scientific integrity would a manuscript be rejected. In these ways, JEI transforms peer-review into an age-appropriate educational experience wherein studentauthors and their teachers are mentored by scientists throughout the publication process. For a more in depth description of how JEI manuscripts are reviewed, see Appendix 1, which contains the full reviewer evaluation form. Journal articles as educational tools We realize that performing original research and writing a scientific manuscript for submission to JEI is not feasible for many middle and high school students and teachers. In order to benefit all students, and not just the select few student-authors, JEI also provides a free, online repository of age-appropriate primary science articles that can serve as an educational resource for all students and their teachers. To facilitate JEI’s mission to incorporate primary journal articles in everyday science education, JEI employs a team of outreach volunteers who provide hands-on instruction at science fairs and festivals, middle and high school science classes, and extracurricular science clubs. We also design and teach workshops for middle and high school science teachers and science department chairs for continuing professional development credits. One teacher-participant of a JEI-organized professional development course commented that JEI “took a topic that seemed out of reach and made it doable.” Another participant stated that JEI’s introduction to primary literature “gives me new ideas on how to include writing in science.” In JEI’s outreach efforts, we demonstrate that the opportunities to use journal articles in the science classroom are vast. JEI articles can be used to teach students about specific scientific concepts contained within the articles, as well as the scientific method and science writing itself. Teachers can benefit from using JEI articles as background reading when the subject pertains to the lesson at hand. For example, there are several JEI articles that investigate some aspect of climate change that have been successfully used to supplement climate education in the high school classroom (2, 4, 7). JEI articles are also useful for teaching broader concepts such as the scientific method and the peer-review and publication processes. For example, one article entitled “The effect of music on heart rate” is scientifically simple enough for middle school students to understand, but still provides an excellent example of developing a hypothesis, designing experiments and discussing implications of the work and limitations of data interpretation (1). We have had great success using this specific article to engage the public at science fairs, to teach high-school students how to critically evaluate a research study, and to educate teachers about the structure of a scientific article. For many more specific ideas about how to incorporate primary articles into the science classroom, a selection of recommended lesson plans is summarized in Table 1, and one of our most popular and easily-adaptable TABLE 1. Ways for students to use primary science articles in the class- room. READING • • • • • Search online for primary articles on a topic of interest as part of a research project Read an article as a background reading assignment instead of a textbook Compare and contrast a research article with a news article on the same subject Journal club A: entire class reads an article and critically evaluates it together Journal club B: each student presents a different part of the article to the class WRITING • • • • • • Write a journal article manuscript instead of a lab report for a preexisting class laboratory Write an abstract to an article provided without its abstract Write a“Results” section that fits a provided piece of data (e.g., a table of results) Peer-review an article by listing each section’s strengths, weaknesses, and needed next steps Peer-review other students’ lab reports and/or manuscripts Design a follow-up question and experiment for an article (then e-mail ideas to study’s author!) Part of JEI’s mission is to encourage the incorporation of primary literature into the middle and high school classroom. Here, we provide a selection of lessons that we and others have used successfully to engage students with JEI articles and other primary literature. Many of these can be done in groups, and/or as part of an active learning module. 122 Journal of Microbiology & Biology Education Volume 17, Number 1 FANKHAUSER and LIJEK: PRIMARY LITERATURE IN THE CLASSROOM activities is described in detail in our accompanying article published in this themed issue (9). Current outcomes and future directions Since JEI began in 2012, we have published over 50 articles written by student-scientists that cover a range of scientific fields, all of which are available for free download on the JEI website (Fig. 2A). Student submissions come from all over the US and abroad (Fig. 2B). While the majority of the articles are written by high school students, there are several articles that have been written by middle school scientists and one article written by elementary school scientists (15). In addition, JEI’s research content is diverse, from psychology to physics, and only continues to grow as JEI increases its publication rate (Fig. 2C). This variety in the reading level and scientific content in JEI articles makes it easy for teachers to find and use articles in a diversity of contexts. At present, JEI is undertaking a formal evaluation to assess how the journal impacts student understanding of the scientific process. Specifically, we are measuring how the review process affects students’ interpretations of the scientific process and their own research. Anecdotally, we have observed positive outcomes from student-authors. This sentiment is most clearly described by one of our student-authors, who said: “I really appreciate all the helpful suggestions of the JEI editorial team, which helped to shape and polish the manuscript to its present state. It would not have been possible without JEI’s behind-thescene help / guidance. It was a great learning experience.” Moreover, we have heard from several teachers and mentors about their experience publishing with JEI. One mentor shared the following with us: “I serve as the managing editor for an Elsevier journal with a relatively high impact factor. I personally was very impressed by the quality of both the technical and editorial feedback provided by the JEI staff.” A two-time student-author, wrote “It was a pleasure to work with JEI again on publishing a paper, and I will (hopefully) be pursuing environmental science in college and as a career in the future. I learned a lot from the experience, and I really appreciated the time and effort of everyone involved in helping me edit and finalize my paper.” These sentiments reflect JEI’s mission: to help students understand the process of science and encourage them to continue to pursue science. As JEI continues to grow, our aspiration is for it to serve as a broadly applicable and widely used tool in the science classroom and beyond. JEI will continue to provide a go-to resource for students to easily read reliable scien- FIGURE 2.  JEI publication statistics as of May 2015.

Over time, we believe that the introduction of primary literature in the middle and high school years will demystify the scientific process and empower citizens of all ages to engage in responsible scientific communication.
