Zusammenfassungen
Blocks-based programming is becoming the standard way to
introduce learners to programming both inside classrooms and
beyond. Educators and designers advocate for this approach
arguing that it is easier to get started and more engaging for the
learner. In this paper, we sought to understand how high school
students enrolled in an introductory programming course
perceived the blocks-based programming approach. Through
cognitive interviews and surveys, we found that students generally
found blocks-based programming to be easier than the text-based
alternative, citing reasons including the natural language labels on
the blocks, the shapes and colors of the blocks, the drag-and-drop
composition mechanism, and the ease of browsing the blocks
library. Students also identified drawbacks to the blocks-based
programming approach, including issues of authenticity,
expressive power, and challenges in authoring larger, more
sophisticated programs. We also found that the differences high
school students see between blocks-based and text-based
programming span the visual interface, the types of programs that
can be authored, as well a different programming practices that
each representation supports.
Von David Weintrop, Uri Wilensky im Text To Block or not to Block, That is the Question (2015) Blocks-based programming tools are becoming increasingly
common in high-school introductory computer science classes.
Such contexts are quite different than the younger audience and
informal settings where these tools are more often used. This
paper reports findings from a study looking at how high school
students view blocks-based programming tools, what they identify
as contributing to the perceived ease-of-use of such tools, and
what they see as the most salient differences between blocksbased
and text-based programming. Students report that numerous
factors contribute to making blocks-based programming easy,
including the natural language description of blocks, the drag-anddrop
composition interaction, and the ease of browsing the
language. Students also identify drawbacks to blocks-based
programming compared to the conventional text-based approach,
including a perceived lack of authenticity and being less powerful.
These findings, along with the identified differences between
blocks-based and text-based programming, contribute to our
understanding of the suitability of using such tools in formal high
school settings and can be used to inform the design of new, and
revision of existing, introductory programming tools.
