本文报告了对中学科学教育中探针软件及相关教材的可行性和教育价值的测试。我们通过考虑成本、教师专业发展和教学设计来解决可行性问题。为了测试我们的方法，我们开发了 2 个中学科学课程单元、6 个可在手持式掌上电脑之间连接的低成本探针，以及用于掌上电脑的 CCLabBook 软件，该软件可呈现课程、与探针连接以进行数据收集和可视化，并支持引导探索。第一年，这些材料由 30 名教师进行了测试，第二年又由其中 8 名教师进行了后续研究。我们发现教师能够在课堂上成功地进行调查，并且通过使用探头和手持设备增强了学生的学习效果。具体来说，学生体验了现象和建模之间的物理关联，这有助于他们发展理解并面对误解。
This paper reports a test on the feasibility and educational value of probeware and associated instructional materials in middle school science education. We addressed feasibility through consideration of costs, teacher professional development, and instructional design. In order to test our approach, we developed 2 middle school science curriculum units, 6 low-cost probes that interface between handheld Palm computers, and CCLabBook software for the Palms that presents the curriculum, interfaces with the probes for data collection and visualization, and supports guided exploration. The materials were tested by 30 teachers in the first year, and in a follow-up study by 8 of those teachers the second year. We found that teachers were able to conduct the investigations successfully in their classrooms, and that student learning was enhanced through the use of the probes and handhelds. Specifically, students experienced the physical correlation between phenomenon and modeling, which helped them to develop understanding and to confront misconceptions.
