美国留学生作业代写:科学探究

坚决执行以科学探究为中心的教与学。科学学习要以探究为中心。探究既是科学学习的目标,又是科学学习的方式。亲历以探究为主的学习活动是学生学习科学的主要途径。学生在科学探究活动中不仅要提出问题、猜想结果、制订计划、观察、实验、制作、收集证据、进行解释、表达和交流等,而且要形成科学的认识。学生科学探究能力的培养和提高离不开真实的探究活动,为此,教师必须让学生通过动手动脑、亲自实践,在感知、体验的基础上建构自己的知识体系,而不是简单地通过讲授把知识和结论教给学生。教师可在每一个单元设计一个探究性问题,制订好探究计划、表格等,一边开展单元教学一边引导学生探究与本单元所学内容相关的问题。分层次教学,螺旋式上升。小学科学素养教育必须面向全体学生。教师在科学素养教育中要有层次地安排科学教育内容,真正做到因材施教,让每个学生都体会到成功和发展。学生只有理解了科学的价值、体验到了成功,才不会丧失对科学的兴趣,提升小学生科学素养的目标才能真正实现。当前,科学教师可根据学生的情况分年级制定一个低、中、高的标准,让每一个学生都能跳一跳摘到果子,即每一个学生在达到基本的科学素养要求后,可继续努力实现更高标准,在不断努力的过程中让每一个学生获得最大程度的发展。

We will resolutely implement teaching and learning centered on scientific inquiry. Scientific learning should be inquiry-based. Inquiry is not only the goal of scientific learning, but also the way of scientific learning. Learning activities based on inquiry is the main way for students to learn science. In scientific inquiry activities, students should not only put forward questions, guess results, make plans, observe, experiment, make, collect evidence, explain, express and communicate, but also form scientific understanding. The cultivation and improvement of students’ scientific inquiry ability is inseparable from real inquiry activities. Therefore, teachers must let students construct their own knowledge system on the basis of perception and experience by using their hands and minds, rather than simply teaching students knowledge and conclusions. Teachers can design an inquiry question in each unit, make inquiry plans, tables, etc., and guide students to explore questions related to the content of this unit while carrying out unit teaching. Hierarchical teaching, spiraling upward. Primary school science literacy education must be open to all students. In scientific literacy education, teachers should arrange the content of science education in a hierarchical way, and teach students in accordance with their aptitude, so that every student can experience success and development. Only when students understand the value of science and experience success, they will not lose their interest in science, and the goal of improving the scientific literacy of primary school students can be truly realized. At present, the science teacher according to the situation of students points for a low, medium and high grade standard, let every student can jump jump picked the fruit, namely each student after meet basic scientific literacy requirement, can continue to work hard to achieve a higher standard, in the process of continuous efforts for the development of each student to obtain the greatest degree.
