Exploring Third-Grade Student Model-Based Explanations about Plant Relationships within an Ecosystem

Elementary students should have opportunities to develop scientific models to reason and build understanding about how and why plants depend on relationships within an ecosystem for growth and survival. However, scientific modeling practices are rarely included within elementary science learning environments and disciplinary content is often treated as discrete pieces separate from scientific practice. Elementary students have few, if any, opportunities to reason about how individual organisms, such as plants, hold critical relationships with their surrounding environment. The purpose of this design-based research study is to build a learning performance to identify and explore the third-grade students’ baseline understanding of and their reasoning about plant–ecosystem relationships when engaged in the practices of modeling. The developed learning performance integrated scientific content and core scientific activity to identify and measure how students build knowledge about the role of plants in ecosystems through the practices of modeling. Our findings indicate that the third-grade students’ ideas about plant growth include abiotic and biotic relationships. Further, they used their models to reason about how and why these relationships were necessary to maintain plant stasis. However, while the majority of the third-grade students were able to identify and reason about plant–abiotic relationships, a much smaller group reasoned about plant–abiotic–animal relationships. Implications from the study suggest that modeling serves as a tool to support elementary students in reasoning about system relationships, but they require greater curricular and instructional support in conceptualizing how and why ecosystem relationships are necessary for plant growth and development.     

The Benefits of Improved Information Literacy Skills on Student Writing Skills: Developing a Collaborative Teaching Model with Research Librarians in Undergraduate Social Work Education

Improving the information literacy and writing skills of undergraduate social work students continues to be an issue for social work educators. In spite of the persistent concern, only a few studies examine the factors influencing these skills and interventions to strengthen them. This article details a faculty–librarian collaborative teaching model to develop students’ information literacy and writing skills through an iterative, peer-reviewed process that includes online and in-class library instruction. Pre- and posttest results from course evaluations, using the learning management system, indicate that students improve their information literacy skills, which in turn improves their writing skills. The article concludes with a discussion of implications for academic and professional development.     

Changes in Science Content Knowledge and Attitudes toward Science Teaching of Educators Attending a Zoo-based Neuroscience Professional Development

Abstract

Informal learning environments often host teachers for learning opportunities, but little is known about the impact of these experiences on teacher professional development (PD). This article describes a unique collaborative PD experience between zoological park personnel and university faculty, examining the impact on teacher content knowledge, attitudes, and classroom lessons. Our findings suggest that the PD improved science content, but made no impact on already high attitudes toward science. In light of the high level of self-reported satisfaction and high frequency of teacher lesson plan use, we propose that the PD had other positive outcomes such as pedagogical knowledge and authentic learning experiences.     

Participatory action research in two primary schools in a rural Tanzanian village: an exploration of factors to cultivate changes in teaching and learning

Access to primary and secondary education in Tanzania has drastically expanded in the past two decades. In response to this success, its ministry is now targeting improvements in educational quality through additional reform. Yet teacher absenteeism, physical abuse, overcrowding, lecture-based pedagogy and a system of accountability based primarily on state and district examinations centered on rote memorization impose great obstacles to students being prepared for future employment and further education. This study draws insights into how traditional teaching and learning methods in one rural village in Tanzania can be changed through examining a collaboratively created intensive after-school program that focused on three content areas and used a participatory action research approach centered on cooperative inquiry. The key elements of the participatory action research approach drawn upon were using a participatory model to create a community of co-learners, designing the curriculum collectively, students collecting data in their communities about identified problems, requiring all participants to contribute, student groups disseminating their findings through presentations and an ongoing support system for teacher development in applying a student-centered pedagogy. Students responded through increased school attendance, confidence, self-esteem and active engagement while teachers incorporated participatory methods of instruction in their classrooms. The factors accounting for the consensus of support by villagers and school and government leaders for the program include community and government buy-in, the creation of a community of learners, consistent follow-up support for teachers and reinforcement of expectations.     

Near-peer Mentor Model: Synergy within Mentoring

The near-peer mentor model provides undergraduates and recent post-baccalaureates in the science, technology, engineering, and mathematics (STEM) fields with an internship in two related disciplines, STEM research and STEM education. The near-peer mentor is both a mentored research intern and a mentor to pre-college students. During the 2013 summer, 43 near-peer mentors from seven sites reported on the benefits, challenges, and personal development they experienced during the internship. In addition, 1,328 pre-college students reported their perceptions of near-peer mentors. In this qualitative study, we indicate that learning by being mentored, while simultaneously acquiring the abilities to mentor and teach, is an effective model for promoting career advancement and the psychosocial support associated with the acquisition of professional behaviors.     

Characterizing pivotal teaching moments in beginning mathematics teachers’ practice

Although skilled mathematics teachers and teacher educators often “know” when interruptions in the flow of a lesson provide an opportunity to modify instruction to improve students’ mathematical understanding, others, particularly novice teachers, often fail to recognize or act on such moments. These pivotal teaching moments (PTMs), however, are key to instruction that builds on student thinking about mathematics. Video of beginning secondary school mathematics teachers’ instruction was analyzed to identify and characterize PTMs in mathematics lessons and to examine the relationships among the PTMs, the teachers’ decisions in response to them, and the likely impacts on student learning. These data were used to develop a preliminary framework for helping teachers learn to identify and respond to PTMs that occur during their instruction. The results of this exploratory study highlight the importance of teacher education preparing teachers to (a) understand the mathematical terrain their students are traversing, (b) notice high-leverage student mathematical thinking, and (c) productively act on that thinking. This preparation would improve beginning teachers’ abilities to act in ways that would increase their students’ mathematical understanding.
