<p> With the continued emphasis in the United States on science teaching reform as a way to increase science learning and the scientific literacy of all, the integration of informal science learning activities like citizen science is emerging as a possible way to enhance formal science teaching and learning. There is a limited but growing number of studies indicating that the general public is learning science content and process from participating in citizen science, but research in this area is just beginning and the use of citizen science projects by teachers in formal classroom settings has barely been examined at all. This qualitative study examined three research questions: 1) What motivates experienced middle school science teachers to use citizen science programs in their classrooms? 2) What do experienced middle school science teachers perceive to be the impact on their students as a result of using citizen science in their classrooms? and 3) What do experienced middle school science teachers perceive as the challenges in using citizen science in their classrooms? Twenty-two middle school teachers from across the United States were interviewed about their motivations and expectations regarding their use of citizen science projects in their classrooms. Using a basic thematic analysis, responses from these semi-structured interviews were coded and themes were developed. Findings indicated that teachers use citizen science to engage their students in authentic science experiences that make a contribution to science and society. Also, teachers perceive that citizen science activities broaden students&rsquo; perspectives and build their agency to make a difference in their environment. Teachers perceived two main challenges with citizen science: making the task meaningful and ensuring that students experience the whole scientific process. This study makes a start at understanding why teachers use citizen science and how they perceive it to impact their students. </p><p>

<p> This descriptive case study examined the meanings public elementary school teachers (N = 13) made of learning to enact citizen science projects in their schoolyards in partnership with a local Arboretum. Utilizing Engestr&ouml;m&rsquo;s (2001) framework of cultural-historical activity theory (CHAT), the Arboretum&rsquo;s outreach program for area Title 1 schools was viewed as an activity system composed of and acting in partnership with the teachers. The major finding was that teachers designed and mastered new ways of teaching (expansive learning) and transformed their citizen science activity to facilitate student engagement and learning. I highlight four important themes in teachers&rsquo; expansive learning: (a) discussion, (b) inclusion, (c) integration, and (d) collaboration. Teacher learning communities formed when colleagues shared responsibilities, formed mentor/mentee relationships, and included student teachers and interns in the activity. This program could serve as a model for elementary school citizen science education, as well as a model for professional development for teachers to learn to teach science and Environmental Education outdoors.</p>

<p> Although research is limited on the effectiveness of co-teaching as a service delivery model for students with disabilities, through observation, many educators have reported positive outcomes with co-teaching (Beninghof, 2011). This case study was designed to examine the implementation of co-teaching in an elementary magnet school in a Midwestern school district driven by science, technology, engineering, arts, and mathematics (STEAM) and with a strong emphasis on personalized learning. General education teachers, special education teachers, and administrators were interviewed three times during the initial implementation school year. In addition, journaling was documented by three of the participants, and co-teaching fidelity checks were completed by the school district&rsquo;s Executive Director of Special Services. After information was gathered and analyzed, it was discovered both students with and without disabilities benefit from co-teaching as a service delivery model. It was also noted there are similarities between the benefits and challenges in a traditional co-taught classroom and a co-taught class in a STEAM elementary school with an emphasis on personalized learning. The benefits of co-teaching far outweigh the detriments. It was further discovered the success of co-teaching is attributed to the pairing of co-teaching partnerships. Finally, the participants shared the need for special education administrators to play a more active role in professional development and the sustainability of co-teaching.</p><p>

<p> Committed elementary teachers of science and engineering, members of a professional learning community called Collaborative Conversations in STEM, were studied to elicit their perceptions of experiences that influenced their commitment to, and their pedagogical content knowledge of, STEM teaching and learning. The hermeneutic phenomenological interviews enabled the teachers to express their beliefs in their own words. Data analysis employed a theoretical framework that investigated teacher epistemology and knowledge in light of their experiences. Findings revealed a web of lifelong experiences unique to each individual, and evidential of the committed elementary scientist-teachers&rsquo; present day values, teaching epistemology, lifelong learning, and emotional and intellectual engagement. Scientist-teachers are individuals whose teaching and learning characteristics reflect those of scientists and engineers.</p><p> Evidence indicated that no single transformative learning experience resulted in those elementary teachers&rsquo; commitment to STEM teaching and learning, but recent professional development activities were influential. Formal K-16 STEM learning was not uniformly or positively influential to the teachers&rsquo; commitment to, or knowledge of, STEM.</p><p> Findings suggest that ongoing professional development for STEM teaching and learning can influence elementary teachers to become committed to actively teaching STEM. The Collaborative Conversations in STEM provided intellectual and emotional engagement that empowered the teachers to provide STEM teaching and learning for their students and their colleagues overcoming impediments encountered in a literacy-focused curriculum. Elementary teachers actively committed to teaching science and engineering can undergo further transformation and emerge as leaders.</p>

The purpose of this study was to examine elementary students' perspectives of a constructivist approach to enhance their knowledge about stress. Participants were fifth grade students in an elementary school in the northeast. Data collection included a pretest-posttest, teacher reflective journal and student interviews. A multiple choice pre-test was administered to students to obtain information about students' knowledge of stress. The pre-test was followed by a four day unit that focused on the concept of stress employing a constructivist approach. The four day unit was monitored in two ways. First, a daily reflective journal was recorded by the teacher about each lesson. Second, students were interviewed at the end of the unit regarding their perceptions of learning through a constructivist approach. A post-test was administered to evaluate students' knowledge. Data analysis for the pre-test consisted of descriptive statistics. The teaching reflective journal and students' interviews were analyzed using constant-comparison. An overview of the results of the study indicates that students reported increased self awareness, appreciation, and understanding of the feelings of others, and enhanced appreciation of human relations from the unit. Other findings indicate that the females scored higher on the pre and post test than the males. Both the individual groups of males and females improved as a result of the unit. The implications of this study may provide educators with insights into the possible effectiveness of a constructivist approach to teaching various health concepts.
