CCMS Project Overview • Professional development and research project • Algebra I and Physical Science • Classroom connectivity technology • Summer Institute – training • T3 conference follow-up, annually ICME-11 TSG 22
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 • 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) • 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 • 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 • 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
Participants • 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 Demographic InformationHLM Sample ICME-11 TSG 22
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 • 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 • 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
Student Views about Mathematics ICME-11 TSG 22
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 • 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
Results • 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
Results • 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
Results • 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) • 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 ICME-11 TSG 22
