Reconceptualizing electronic field trips: a Deweyian perspective     

Jerrell C. Cassady  Laurie J. Mullen 《Learning, Media and Technology》2006,31(2):149-161

Electronic field tripping is a relatively new form of large‐scale distance education that attempts to provide contextually rich learning materials embedded within a coherent educational content base. Using Dewey’s (1943 Dewey, J. 1943. The child and the curriculum: the school and society, Chicago: University of Chicago Press.  [Google Scholar]) framework for the natural learning impulses of children, we describe the potential pedagogical benefits afforded by electronic field trips (EFTs). We outline a shift in distance education from a techno‐centric focus on hardware and logistics to the inherent features of children’s desires to explore their world, which represents an alteration of perspective and purpose in understanding computer technologies in classroom settings. Finally, we demonstrate that while each independent element of the EFT experience promotes one or more of Dewey’s impulses, bringing together all the resources provided for EFTs fosters deeper connections, more engaged learning, and contextualized distance learning true to the spirit of live field trips.  相似文献   

Synergy Between Teacher Practices and Curricular Scaffolds to Support Students in Using Domain-Specific and Domain-General Knowledge in Writing Arguments to Explain Phenomena     

Katherine L. McNeill  Joseph Krajcik 《学习科学杂志》2013,22(3):416-460

We investigated how 2 different curricular scaffolds (context-specific vs. generic), teacher instructional practices, and the interaction between these 2 types of support influenced students' learning of science content and their ability to write scientific arguments to explain phenomena. The context-specific scaffolds provided students with hints about the task and what content knowledge to use in or incorporate into their writing. The generic scaffolds supported students in understanding a general framework (i.e., claim, evidence, and reasoning) regardless of the content area or task. This study focused on an 8-week middle school chemistry curriculum that was enacted by 6 teachers with 578 students during the 2004–2005 school year. Analyses of identical pre- and posttests as well as videotapes of teacher enactments revealed that the curricular scaffolds and teacher instructional practices were synergistic in that the effect of the written curricular scaffolds depended on the teacher's enactment of the curriculum. The context-specific curricular scaffolds were more successful in supporting students in writing scientific arguments to explain phenomena, but only when teachers' enactments provided explicit domain-general support for the claim, evidence, and reasoning framework, suggesting the importance of both types of support in successful learning environments.  相似文献

Enhancing Elementary Pre-service Teachers’ Plant Processes Conceptions     

Stephen L. Thompson  Christine Lotter  Xumei Fann  Laurie Taylor 《Journal of Science Teacher Education》2016,27(4):439-463

Researchers examined how an inquiry-based instructional treatment emphasizing interrelated plant processes influenced 210 elementary pre-service teachers’ (PTs) conceptions of three plant processes, photosynthesis, cellular respiration, and transpiration, and the interrelated nature of these processes. The instructional treatment required PTs to predict the fate of a healthy plant in a sealed terrarium (Plant-in-a-Jar), justify their predictions, observe the plant over a 5-week period, and complete guided inquiry activities centered on one of the targeted plant processes each week. Data sources included PTs’ pre- and post-predictions with accompanying justifications, course artifacts such as weekly terrarium observations and science journal entries, and group models of the interrelated plant processes occurring within the sealed terraria. A subset of 33 volunteer PTs also completed interviews the week the Plant-in-a-Jar scenario was introduced and approximately 4 months after the instructional intervention ended. Pre- and post-predictions from all PTs as well as interview responses from the subgroup of PTs, were coded into categories based on key plant processes emphasized in the Next Generation Science Standards. Study findings revealed that PTs developed more accurate conceptions of plant processes and their interrelated nature as a result of the instructional intervention. Primary patterns of change in PTs’ plant process conceptions included development of more accurate conceptions of how water is used by plants, more accurate conceptions of photosynthesis features, and more accurate conceptions of photosynthesis and cellular respiration as transformative processes.  相似文献

Secondary science students’ beliefs about class discussions: a case study comparing and contrasting academic tracks     

Diane Silva Pimentel  Katherine L. McNeill 《International Journal of Science Education》2016,38(12):2047-2068

The dialogue that occurs in science classrooms has been the subject of research for many decades. Most studies have focused on the actual discourse that occurs and the role of the teacher in guiding the discourse. This case study explored the neglected perspective of secondary science students and their beliefs about their role in class discussions. The study participants (N?=?45) were students in one of the three differentially tracked chemistry classes taught by the same teacher. Findings about the differences that exist among students from different academic tracks are reported. While it seems that epistemological beliefs focusing on content are common for the students in this study, the students' social framing in the different tracks is important to consider when teachers attempt to transition to more dialogic forms of discourse. Some key findings of this study are (a) students’ beliefs that science is a body of facts to be learned influenced the factors they deemed important for whole-class discussion, (b) students from the lower-level track who typically were associated with lower socioeconomic status were more likely to view their role as passive, and (c) students’ comfort level with the members of the class seemed to influence their decisions to participate in class discussions.  相似文献   

Teachers’ enactments of curriculum: Fidelity to Procedure versus Fidelity to Goal for scientific argumentation     

Katherine L. McNeill  Lisa M. Marco-Bujosa  María González-Howard  Suzanna Loper 《International Journal of Science Education》2018,40(12):1455-1475

Fidelity of implementation (FOI) has received attention in calls for funding and research; however, there are numerous ways of conceptualising and measuring this construct. We argue that this conceptualisation is important for recent reform efforts focused on science practices. Consequently, we explored FOI in the context of the enactment of a middle-school curriculum focused on one particular science practice, argumentation. We coded videos of five teachers’ enactments of argumentation lessons using two different fidelity coding schemes. First, Fidelity to Procedure targeted teachers’ adherence to the order and types of procedures. Second, Fidelity to Goal examined teachers’ adherence to the overarching argumentation goals. This analysis resulted in case studies that illustrate distinct patterns in the teachers’ curriculum enactments. One case in particular, Ms Newbury, received a low score for Fidelity to Procedure, but a high score for Fidelity to Goal. She altered procedures to provide her students, all of whom were English Language Learners, with different linguistic supports, but maintained the overarching argumentation goals. Consequently, we argue that FOI for goals may better capture whether teachers’ enactments are supporting students in the science practices. Furthermore, the results suggest the importance of educative curriculum including rationales for the curricular goals.  相似文献
