肖像画：科学领域的女性

一项融合公民教育与科学的跨学科项目，组织七年级学生开展肖像画的数字化创作。

首先，数学与科学教师克里斯蒂娜·卡泰拉（Cristina Catella）带领学生搜寻在不同历史时期中，以自身发现推动人类科学、数学与技术进步的女性科学家。学生们收集了这些女性科学家的肖像，并配以包含其生平信息与专业领域的文字说明。每位学生选择一位女性科学家，使用 iPad 上的 Sketchbook 应用程序及数字绘图笔绘制其肖像。

将照片插入 Sketchbook 页面后，在新建的绘图图层上，我们以连续线条勾勒肖像细节，同时简化线条，使细节风格化，并将线条归纳为封闭形状。

封闭形状便于使用“油漆桶”工具为各区域填色，从而获得饱满、均匀的色彩效果。完成人物着色后，可借助“喷枪”工具添加阴影与明暗，使肖像融入一定的明暗对比（chiaroscuro）。

随后，为肖像添加单色背景，并配以标题栏及文字说明，注明科学家的姓名、个人资料与籍贯、专业领域，以及最具代表性的科学发现。

这些肖像画以 A3 幅面打印并覆膜，将用于装饰科学教室及数理科学学习区的走廊，并配以法比奥拉·贾诺蒂（Fabiola Gianotti）的名言：“对科学的热情，既无性别之分，亦无国界之限。”

Portraits: Women in Science

An interdisciplinary project with citizenship education and science, involved the 7th grade students in working on the digital processing of the portrait.

First of all, mathematics and science teacher Cristina Catella worked with the students searcing for women scientists who, with their discoveries, contributed to the scientific, mathematical and technological progress of humanity in various historical eras. The portraits were collected and combined with captions with data and specializations. Each student chose a woman of science and created her portrait using the Sketchbook App on iPad with digital pens for drawing.

The photo was inserted into the Sketchbook page and on a new layer of drawing we drew the details of the portrait in continuous lines, simplifying the lines in order to stylize the details and reduce the lines to closed shapes.

The closed shapes allow us to color the areas with the “bucket” tool, to have compact and uniform colors. Once the figure has been coloured, shadows and shades can be added with the “airbrush” tool in order to integrate the portrait with some chiaroscuro.

The portrait was then completed with a monochrome background, a title block and captions indicating the name, personal data and place of origin, the specialization of the scientists and the most relevant discoveries.

The portraits have been printed in A3 format and laminated, and they will decorate the science classroom and the corridors of the scientific-mathematics learning area, accompanied by a quote by Fabiola Gianotti “The passion for science has neither gender nor passport” .
