工欲善其事必先利其器,教学改革也是如此。尤其是对研究绘制和阅读工程图样的原理和方法的工程制图这门学科的教学改革尤其重要。虽然我们以前在这门课程的教学中引入了多媒体和计算机辅助绘图软件Autocad,教学效果虽然有所改善,但感觉远没达到预期效果。 Workers should do their thing first thing good, teaching reform is also true. In particular, teaching reform in engineering drawing, a discipline that studies the principles and methods of drawing and reading engineering drawings, is of particular importance. Although we have previously introduced Autocad, a multimedia and computer-aided drawing software, into the teaching of this course, the teaching effect has improved, but the result is far from achieving the expected result.
