| Summary: | 碩士 === 中原大學 === 化學研究所 === 91 === Ⅰ：Demonstrative Experiment of Magnetic Material
Abstract
This demonstrative experiment is conducted with self-made teaching tool. The materials therefore are those commonly sold in the market and easy to acquired as well as inexpensive. After assembly the tool shall be equipped with the benefits of light and convenient, space economy, portable and not restrained by time or space, yet can be used in teaching or for demonstration. The functioning between the test object and the magnet is manifested through pendulum swing format. The magnetic substance is invested with very conspicuous deviating angle. The teaching tool is simple to operate while clearly allow observation of the magnetic material being attracted, which is the major difference from other people’s teaching or classroom as well as the ultimate goal of this experiment. From the experiment it is derived that the method cannot be quantified, and can only be verified via students’ hands-on operation. In addition, it not only enables students to verify the common knowledge of magnetic attraction property, it further sheds light on how a magnetic substance can attracted to a certain angle in macro view. When comparing various compound specimens through unit mass functioning, iron and manganese compounds show the greatest deviating angles, which is related to the count of non-paired electrons.
Ⅱ：A Comparative Study on the First Secondary School Year’s Natural Sciences & Living Technologies Course Concerning
the Earth Science under the Nine-Year Systematic Curriculum
and the Current Third Year Programme
Abstract
This study is focused on comparing the contents of the new and old course versions of the secondary school curriculum, using the old edition of third year textbook and the new edition of ‘natural sciences and living technologies’ for the comparative analysis. Predicated on the interim outline for the nine-year systematic elementary and secondary education, the course of ‘natural sciences and living technologies’ is evaluated through 8 segmented competency indices and 10 basic competency indices, in concomitant with interviewing teachers of the secondary school level ‘natural sciences and living technologies’ and ‘Earth science’ in the north and south districts of Taoyuan County.
The study results are as follows: The contents of the old and new editions vary. The new one is emphatic of ‘applying technology and information’ while the old version stresses ‘career planning and lifelong learning’. In terms of degree of difficulty, the old version is more challenging, but endowed with greater logic that makes it easier to connect, allowing students to attain higher intellect through knowledge, understanding, application, analysis, incorporation and evaluation, and also matches Benjamin S. Bloom’s goal of education on the cognition aspect.
