Description
Astronomical learning materials in which spectral data are dealt with were developed to provide high school students opportunities to learn astronomy. Two kinds of astronomical topics, elemental identification of solar absorption lines and rotational velocity measurements of spiral galaxies, were selected as material subjects. Each material contains spectral data and spreadsheets and macro commands are built into spreadsheets to reduce analytical work burden. An astronomical image processing software, Makali`i, is adopted as a default image processor. To evaluate the efficiency of the learning materials, the trial practice of the materials were carried out. As a result, the materials got favorable response from over 80% of experimental participants. On the other hand, it is found that considerable fraction of participants felt difficulty to understand the material contents.
