Though research has shown that students do not have adequate understandings of nature of science (NOS) by the time they exit
high school, there is also evidence that they have not received NOS instruction that would enable them to develop such understandings.
How early is “too early” to teach and learn NOS? Are students, particularly young students, not capable of learning NOS due
to developmental unreadiness? Or would young children be capable of learning about NOS through appropriate instruction? Young
children (Kindergarten through third grade) were interviewed and taught about NOS in a variety of contexts (informal, suburban,
and urban) using similar teaching strategies that have been found effective at teaching about NOS with older students. These
teaching strategies included explicit decontextualized and contextualized NOS instruction, through the use of children’s literature,
debriefings of science lessons, embedded written NOS assessments, and guided inquiries. In each context the researchers interviewed
students prior to and after instruction, videotaped science instruction and maintained researcher logs and field notes, collected
lesson plans, and copies of student work. The researchers found that in each setting young children did improve their understandings
of NOS. Across contexts there were similar understandings of NOS aspects prior to instruction, as well as after instruction.
There were also several differences evident across contexts, and across grade levels. However, it is clear that students as
young as kindergarten are developmentally capable of conceptualizing NOS when it is taught to them. The authors make recommendations
for teaching NOS to young children, and for future studies that explore learning progressions of NOS aspects as students proceed
through school. 相似文献

This study explores the development of professional identity as a teacher of nature of science (NOS). Our research question was ‘How can a teacher develop a professional identity as an elementary teacher of NOS?' Through a researcher log, videotaped lessons, and collection of student work, we were able to track efforts in teaching NOS as part of regular classroom practice. A team of four researchers interpreted the data through the Beijaard et al. professional identity framework and found that it was not as simple and straightforward to teach NOS as we predicted. Development of professional identity as a teacher of NOS was influenced by contextual factors such as students, administration, and time, as well as personal struggles that were fraught with emotion. Development took place through an interpretation and reinterpretation of self through external factors and others' perceptions, as well as the influence of sub-identities. 相似文献

This study explored third-grade elementary students' conceptions of nature of science (NOS) over the course of an entire school year as they participated in explicit-reflective science instruction. The Views of NOS-D (VNOS-D) was administered pre instruction, during mid-school year, and at the end of the school year to track growth in understanding over time. The Young Children's Views of Science was used to describe how students conversed about NOS among themselves. All science lessons were videotaped, student work collected, and a researcher log was maintained. Data were analyzed by a team of researchers who sorted the students into low-, medium-, and high-achieving levels of NOS understandings based on VNOS-D scores and classwork. Three representative students were selected as case studies to provide an in-depth picture of how instruction worked differentially and how understandings changed for the three levels of students. Three different learning trajectories were developed from the data describing the differences among understandings for the low-, medium-, and high-achieving students. The low-achieving student could discuss NOS ideas, the medium-achieving student discussed and wrote about NOS ideas, the high-achieving student discussed, wrote, and raised questions about NOS ideas. 相似文献
