Establishing assessment criteria and breakthrough points for drawing ability

The "ability of realistic drawing" especially realistic drawing ability has been an important measure in assessing the spiritual world of humankind; However, several points in individual teaching strategy remain yet to be clarified in the established practice of group teaching how to draw: 1. How does one assess the artist's skill level? 2. Which abilities should be included in the scale used to assess drawing ability? 3. Of these abilities, which ones can be learned in a short time and which ones require a long time? 4. How does drawing ability evolve to reflect quantitative and qualitative changes as the learning time accumulates? This study attempts to answer the four questions posed above in an analytical and quantifiable way by obtaining empirical data from three drawing experts and four student groups with the aim to establish a set of assessment criteria for drawing ability. With a comprehensive and effective set of assessment criteria established for drawing ability, that the contributions from this study could enable teachers to assist learners not only save time on guesswork, but also provide tailored and specific breakthrough teaching strategies.
