Learning On-Demand

The ATI Professional Development Department has recently released a new series of live Learning On-Demand sessions to assist educators in becoming proficient users of Galileo technology.

Our K-12 series focuses on implementing interventions and creating formative assessments to analyze the impact of initial instruction and interventions. Click here to learn more about our upcoming K-12 Learning On-Demand sessions.

NEW! Our Pre-K series provides guidance on entering and monitoring child observations, accessing Galileo’s Model Curriculum and how Galileo data may be used to analyze children’s progress. Click here to learn about our Pre-K Learning On-Demand sessions.

If you can’t attend a live session, each session is recorded and available in the Professional Development Forum. Both live and recorded Learning On-Demand sessions are complimentary.

Extensive Statistical Analyses Sets Galileo K-12 Online Apart

ATI research uses advanced statistical procedures to address assessment goals associated with standards-based education. One research focus includes statistical analyses of items and assessments. Item Response Theory (IRT) a statistical analysis procedure, makes it possible to place scores from different assessments on a common scale. If IRT were not used, a difference in scores between two tests could be due to differences in test difficulty or changes in student achievement, or both. IRT considers both item difficulty and achievement level making it possible to produce an ability score and to measure academic progress. This cannot be accomplished by assessments that provide only raw data (percent/number correct).

ATI routinely provides psychometric analyses of ATI and district developed assessments that have been administered to a group of students large enough to support such analyses. Item analysis uses IRT techniques to determine item parameter estimates and assessment reliability. Access to a variety of statistical information is available through the Galileo K-12 Online Item Analysis and Item Parameter reports.

ATI also utilizes categorical data analysis procedures to determine the risk of not meeting standards. Categorical data analysis techniques informed development of the Galileo Risk Assessment Report. The report classifies students with respect to their risk of failing to show mastery on the statewide test based on their performance on one or more district -wide assessments. Structural equation modeling  is also used to identify variables that impact learning. Investigations using structural equation modeling have revealed the effects of student learning at different points throughout the year on performance on the statewide test. Finally, value-added modeling is used to identify factors affecting learning.

Galileo Score Compiler A Crucial Component of ATI’s Instructional Effectiveness System

Galileo K-12 Online supports instructional effectiveness initiatives within one customizable system of which a vital component is the Score Compiler. The Galileo Score Compiler allows users to select a variety of measures (e.g. teacher observations, student growth data, and student performance levels on state tests), place scores from these measures on a common scale, and then weight each measure as desired. District or charter-determined scoring provides the rating scale by which instructional effectiveness scores are calculated. The Score Compiler provides a continuous and final instructional effectiveness score at the teacher, school, or district level with a detailed explanation of how the scores are compiled available from the View Calculations link.

The types of measures that can be included in the Score Compiler are limitless. One of the most commonly used measures among ATI charter/ district partners includes Categorical Growth scores at both the teacher and the school level. These scores provide data about whether a student has exceeded, maintained, or failed to maintain expected growth based on a pre/posttest during an instructional-time period. Although Categorical Growth scores are the most popular, other types of scores based on any Galileo benchmark or formative assessment may also be incorporated into the Score Compiler. The Score Compiler also allows for external test scores (e.g., state tests, Dynamic Indicators of Basic Early Literacy Skills [DIBELS], AP Scores) to be uploaded into Galileo at the student, teacher, or school level. Measures such as mean scores, median scores, and percentages of students can be automatically calculated and compiled.

The Galileo Score Compiler can be helpful in a number of ways. The Score Compiler assists educators to:
• Demonstrate student growth (Categorical Growth and Achievement Data) at the teacher or school level using this year’s or last year’s enrollment with Galileo’s Instructional Effectiveness pre- and posttest assessments. Exclude specific students from data calculations when necessary.
• Determine final calculations by combining various forms of data and calculate final performance levels. Configure the compilers to weight specific sets of data appropriately.
• Configure cut points by applying point values, and performance level verbiage specific to district requests.

Administrators will find that the Score Compiler provides support to:
• Configure security settings at different levels.
• Determine a rating scale by inputting district teacher performance rubrics using district scoring, notate what type of evidence was used for the observation and include administrator observation notes.
• Provide teachers with a detailed explanation of how their scores are compiled.
• Attach files to specific staff members.
• Monitor Student Learning Observations - coming soon.
