Impact of interactive online units on learning science among students with learning disabilities and English learners

The purpose of this study was to document the design, classroom implementation, and effectiveness of interactive online units to enhance science learning over 3 years among students with learning disabilities, English learners, and general education students. Results of a randomised controlled trial with 2,303 middle school students and 71 teachers across 13 schools in two states indicated that online units effectively deepened science knowledge across all three student groups. Comparing all treatment and control students on pretest-to-posttest improvement on standards-based content-specific assessments, there were statistically significant mean differences (17% improvement treatment vs. 6% control; p?相似文献   

Over reported and misunderstood? A study of teachers’ reported enactment and knowledge of inquiry-based science teaching

Science education reforms worldwide call on teachers to engage students in investigative approaches to instruction, like inquiry. Studies of teacher self-reported enactment indicate that inquiry is used frequently in the classroom, suggesting a high level of proficiency with inquiry that would be amenable to inquiry reform. However, it is unclear whether the high frequency of self-report is based on sound knowledge inquiry. In the absence of sound knowledge, high rates of self-reported enactment would be suspect. We conducted a study to measure teachers’ knowledge of inquiry as it related to the known, high frequency of reported enactment. We developed a multidimensional survey instrument using US reform documents and administered it to 149 K–12 teachers at a national science teachers’ conference. The majority of the teachers surveyed did not report inquiry enactment based on well-structured knowledge of inquiry. Interviews with participants showed how teachers could readily map non-inquiry activities onto inquiry statements taken directly from reform documents. From these results we argue that teachers often believed they were enacting inquiry, when likely they were not. We further reason that teachers may struggle to interpret and enact inquiry-related requirements of science education reform and will need support distinguishing inquiry from non-inquiry practices.     

小学数学探究式课堂教学的探讨

在新课程改革的背景下,教师逐渐意识到探究式教学方式在课堂教学中的重要性,通过探究式教学,不仅可以有效发挥学生在学习以及课堂教学中的主体作用,进而促进学生专业能力以及综合素质的提升,而且有助于学生在进行探究式学习的过程中提高其思考、分析以及解决问题的能力,进而实现课堂高效教学。在小学阶段的数学教学中采用探究式的教学方式,可以充分调动学生数学学习兴趣,使其自愿参与到数学课堂教学中,同时,促使学生自主思考和分析学习中的数学问题,进而获得探究及创新能力的发展。     

Computers and Traditional Teaching Practices: Factors influencing middle level students’ science achievement and attitudes about science

The purpose of this study was to examine the association of middle school student science achievement and attitudes toward science with student-reported frequency of using computers to learn science and other classroom practices. Baseline comparison data were collected on the frequency of student-centred teaching practices (e.g. the use of group experiments during science class) and traditional teaching practices (e.g. having students copy notes during science class) to learn science. The student sample was composed of 294 seventh-grade students enrolled in middle school science. Multiple regression was used to investigate the association of attitudes toward science, student-centred teaching practices, computer usage, and traditional teaching practices with science achievement. Both attitudes toward science and student-centred teaching practices were positively associated with science achievement, and student-centred teaching practice was positively associated with attitude toward science. Computer usage was found to have a negative association with student achievement, which was moderated by traditional teaching practices.
