'''As of version 83, major changes have been made, see [[Activities/Turtle Art]] for a description of the current version of Turtle Art. This page has been retained for historical reasons for versions prior to version 83.'''
    
Turtle Art is a [[Taxonomy#Fructose:_The_set_of_demonstration_activities|fructose module]], so it is included as part of the standard Sugar (sucrose) distribution.

Turtle Art is intended to be a stepping stone to  the Logo programming language, but there are many restrictions compared to Logo. (Only numeric global variables and stack items are available, no lists or other data-structures. The conditionals and some of the functions only take constants or variables, not expressions. Limited screen real-estate makes building large programs unfeasible.) However, you can export your Turtle Art creations to [#Exporting to Berkeley Logo|Berkeley Logo]]. The [[Activities/TAExperimental|experimental version of Turtle Art]] also has a (limited) facility for sensor input, so, for example, you can move the Turtle based upon sound volume or pitch.

A [[Activities/Turtle Art/Templates|portfolio feature]] lets you use Turtle Art to create multimedia slide shows from material retrieved from your Journal. The basic idea is to import images (and eventually movies, audio, and text files) into slide templates, not unlike Powerpoint, and then show a presentation by stepping through them. The portfolio includes the typical major functions of presentation software: an editor that allows text to be inserted and formatted (this is largely incomplete), a method for inserting images (from the Journal), and a slide-show system to display the content. What makes it a bit different than tools such as Powerpoint is that you can program your slides using Turtle Art blocks. Turtle Art also has an export-to-HTML function so that presentations can be viewed outside of the Sugar environment.

In the era of high-stakes testing, we have the means to measure “which child knows more”; these data tell us about relative merit of the school in which a child is enrolled. The Turtle Art portfolio feature is an assessment tool that shows “what a child knows”; children become the curators of their own work. They advance their own learning and help their teachers, parents, and school administrators understand better the depth and breadth of what they have learned.

A [http://chronicle.com/wiredcampus/article/3668/electronic-portfolios-a-path-to-the-future-of-learning recent article] in the ''Chronicle of Higher Education'' claims:
 +
# ePortfolios can integrate student learning in an expanded range of media, literacies, and viable intellectual work;
 +
# ePortfolios enable students to link together diverse parts of their learning including the formal and informal curriculum;
 +
# ePortfolios engage students with their learning;
 +
# ePortfolios offer ''colleges'' a meaningful mechanism for accessing and organizing the evidence of student learning.
    
Turtle Art portfolios engage children in the process of reflecting on their work—what they have done, how they have done it, and how success these efforts have been—as they create a multimedia narrative to show their teachers, parents and peers what they have learned. Turtle Art Portfolio builds upon the journaling functionality of the Sugar learning platform, where every action or activity a child takes in the classroom is automatically recorded in a folder: (1) by enabling the child to select important learning achievements, be they in reading, writing, arithmetic, arts, music, physical education, history and social science, etc. Children answer questions such as “I chose this piece because...” (2) creating a multimedia narrative presentation from their selections (including audio voice-overs and video), reflective of the multiple ways in which children learn; and (3) sharing their presentation with classmates, both to celebrate what they have learned, but also to engage in a critical dialog about their work.

The classroom teacher can add addition assessment slides to the portfolio about themes such as work habits and personal growth, as part of an archive that travels with a child across grade levels. Through juxtaposition, the child and teacher can see what has changed over the course of the years, trends, and areas for improvement, Also, a classroom portfolio can be assembled as part of a teacher-assessment process.

Turtle Art supports a simple sharing model. Whomever joins a shared activity will get a copy of the current state of the project from the initiator of the share. Subsequent changes to the project are shared between all participants. It is not recommended to share among more than 2–3 people at a time.

Subsequent changes to the project are shared between all participants. It is not recommended to share among more than 2–3 people at a time. Please note that if different versions of Turtle Art are used in the same share instance, there may be problems, as old versions won't know how to handle new bricks introduced in later versions.
