The TI-Navigator™ Connected Classroom

The TI-Navigator System allows the teacher to:

  • Create a collaborative learning environment
  • Engage in formative assessment by way of immediate feedback
  • Enhance classroom management of TI graphing technology

ICME-11, TSG 22 12 July 2008

ICME-11 TSG 22

theoretical framework
Theoretical Framework
  • Social-constructivist models of teaching and learning
  • Technology-assisted formative assessment
  • Classroom environments that foster self-regulated learning and mastery orientation
  • Classroom discourse processes
  • Classroom environment centeredness constructs

ICME-11 TSG 22

prior research roschelle penuel abrahamson 2004
Prior Research (Roschelle, Penuel, & Abrahamson, 2004)
  • Students:
    • Increased student engagement, understanding, and interactivity
    • Improved classroom discourse
    • Knowledge of classmates’ learning
  • Teachers:
    • Improved pre- and post- assessment of student learning
    • Increased awareness of student difficulties
    • Improved questioning

ICME-11 TSG 22

research questions
Research Questions
  • How does teachers’ use of connected classroom technology affect:
    • Student achievement in algebra 1?
    • Self-regulated learning strategic behavior?
    • Student views of mathematics?

ICME-11 TSG 22

research design
Research Design
  • Year 1 (2005-2006) – Algebra I
  • Randomized assignment to treatment and control/delayed treatment groups
  • Cross-over design – control group provided treatment in second year of participation
  • Mixed methodology

ICME-11 TSG 22

  • Initial data – 127 Algebra I teachers and 1,761 students from 28 states
  • 81 (64%) teachers had complete data at the end of year 1 (Rx = 39; C = 42)
  • 1,128 students from 68 classrooms (84% of 81) with adequate data (n>9; Rx=617; 50.2% female; C=511; 56.8% female)
  • Initial and final samples were not different on teacher demographic characteristics
  • Final sample treatment and control differ: % free/reduced lunch and school location

ICME-11 TSG 22

teacher data collection
Teacher Data Collection
  • Demographic Information Form
  • Technology Use and Professional Development Survey
  • Teacher Instructional Practices and Beliefs Survey (TIPBS)
  • Implementation—Teacher Interviews (inter-rater reliability ranged from .80 to 1.00)
  • Level of content implementation

ICME-11 TSG 22

student measures
Student Measures
  • Algebra I pretest
  • Algebra I posttest
    • Total score
    • Visual, Mechanical, and Pure Symbolic subtests
  • Student Beliefs about Mathematics
  • Motivated Strategies for Learning Questionnaire (Pintrich, Smith, Garcia, & McKeachie, 1991)

ICME-11 TSG 22

measures algebra i
Measures – Algebra I
  • Algebra pretest – 30 item; 23 multiple choice, 3 short-answer, and 4 extended response
  • Algebra post-test – 30 items; 24 multiple choice, 1 short-answer, and 5 extended response
  • 11 items overlap between the pre- and post-tests

ICME-11 TSG 22

motivated strategies for learning questionnaire
Motivated Strategies for Learning Questionnaire
  • 6 Motivation subconstructs
    • Intrinsic/Extrinsic Goal Orientation; Task Value; Control of Learning Beliefs; Self-Efficacy; Test Anxiety
      • Alpha range = 0.67 to 0.92
  • 5 Learning Strategies subconstructs
    • Rehearsal; Elaboration; Organization; Critical Thinking; Metacognitive Self-Regulation
      • Alpha range = 0.73 to 0.80
  • 4 Resource Management Strategies Subconstructs
    • Time and Study Environment; Effort Regulation; Peer Learning; Help Seeking
      • Alpha range = 0.50 to 0.65

ICME-11 TSG 22

data analyses
Data Analyses
  • Cronbach’s alpha reliability estimates
  • IRT analysis conducted to ensure technical quality of Algebra pre- & post-test
  • Hierarchical Linear Modeling (HLM) to examine effect of treatment
    • Accounting for nested data
    • Pretest data included as covariate
    • Two-level models consisting of within-class (level 1) and between-class (level 2)

ICME-11 TSG 22

  • Significant treatment effect (ES=0.30) after controlling for student pretest scores, teacher’s years of experience, teacher’s gender, and percent of free/reduced lunch
    • Students taught by treatment group teachers performed about 2 out of 37 points higher than control students
  • Level of teacher knowledge about students as a result of TI-Navigator use was positively related to with student performance (ES=0.36)
  • Frequency and level of technology implementation as well as level of instructionalchange with technology were not associated with the outcome

ICME-11 TSG 22

  • Teaching experience was positively associated with achievement
  • Percentage free/reduce lunch not associated with outcome
  • Students of female teachers performed higher than male teachers (ES = .41)
  • Level of content coverage (implementation) was not associated with student performance
  • None of the other teacher survey constructs were associated with student outcome

ICME-11 TSG 22

  • On visual dimension, after controlling for percentage of free/reduced lunch, positive association between outcome and …
    • Treatment status (ES = 0.34)
    • Frequency of technology use (ES = 0.32)
    • Level of teacher knowledge about students as a result of TI-Navigator use (ES = 0.40)
    • level of instructional change with technology(ES = 0.48)
  • For mechanical and pure symbolic questions, none of the variableswere positively associated with the outcome

ICME-11 TSG 22

results con t
Results (con’t)
  • Treatment positively affected student Self-efficacy/math performance expectations with (ES=0.16)
  • No differences for beliefs about mathematics, confidence, anxiety, or usefulness related to treatment
  • No differences for motivation, learning strategies, or resource management strategies related to treatment
