ROOTS (Whole Number Foundations Level K)
Study: Clarke et al. (2020)

Summary

ROOTS is a 50-lesson kindergarten intervention program designed to develop procedural fluency with and conceptual understanding of whole number concepts. ROOTS is delivered by instructional assistants to small groups consisting of 4-5 students, 4 to 5 times per week, for 10-12 weeks during the second half of the school year. Each ROOTS lesson is approximately 20 minutes in duration and includes 4 to 5 brief math activities that center on whole number concepts and skills. ROOTS provides in-depth instruction in whole number concepts by linking the informal mathematics developed prior to kindergarten to the formal mathematics of kindergarten. Specifically, ROOTS focuses on three key areas of whole number understanding (a) Counting and Cardinality (b) Number Operations and (c) Base 10/Place Value.

The minimum qualifications for ROOTS instructors are that they be instructional assistants and/or paraprofessionals. The program does not assume that the instructor has expertise in a given area. In the research study, instructional assistants (IAs) attended two half-day trainings, and regular on-going coaching support was provided to facilitate high levels of implementation fidelity. The initial workshop focused on the instructional objectives related to Lessons 1-25, the critical content of kindergarten mathematics, small-group management techniques, and the instructional practices that have been empirically validated to increase student math achievement. In the second workshop the same format was followed as in workshop 1 but with a focus on the second half of the curriculum, Lessons 26-50. Workshops were organized around three principles: (a) active participation, (b) content focused, and (c) coherence. Practitioners may obtain ongoing professional/technical support by contacting: Email: support@dibels.uoregon.edu Phone: 1-888-497-4290


Training materials were developed and field-tested initially as part of an IES grant to study the impact of a core kindergarten mathematics program. Materials and manuals underwent initial development and continued refinement as part of the work of that grant. A second grant four year grant from IES to study the efficacy of ROOTS allowed further minor refinement of curricular and support material. All IES studies were conducted with the target population of interest.

Participants Full Bobble

Describe how students were selected to participate in the study:
A total of 138 kindergarten classrooms participated in the efficacy trial. Within the 138 participating classrooms, all kindergarten students with parental consent were screened in late fall of their kindergarten school year.

Describe how students were identified as being at risk for academic failure (AI) or as having emotional or behavioral difficulties (BI):
All students with parental consent from the 138 classrooms were screened in the late fall of their kindergarten year. The screening process included the Assessing Student Proficiency in Early Number Sense (ASPENS; Clarke et al., 2011) and the Number Sense Brief (NSB; Jordan et al., 2010), which are standardized measures of early mathematics proficiency. Students were eligible for the ROOTS intervention and thus considered at risk for mathematics difficulty (MD) if they received an NSB score of 20 or less and a composite ASPENS score in the strategic or intensive range. After being determined eligible for the ROOTS intervention, students’ NSB and ASPENS scores were separately converted into standard scores and then combined to form an overall composite score for each at-risk student. All data management was conducted by the project’s independent evaluator. Composite scores within each classroom were then rank ordered, and the 10 ROOTS-eligible students with the lowest composite scores were randomly assigned to one of three conditions: (a) 2: 1 ROOTS group, (b) 5: 1 ROOTS group, or (c) no-treatment control condition. The 10 ROOTS-eligible students were then pre-tested using the Test of Early Mathematics Ability (TEMA-3). The average TEMA-3 raw score at pretest was 17.0 for the sample, which corresponds to the 19th percentile according to TEMA-3 scoring documents.

ACADEMIC INTERVENTION: What percentage of participants were at risk, as measured by one or more of the following criteria:
  • below the 30th percentile on local or national norm, or
  • identified disability related to the focus of the intervention?
40.2%

BEHAVIORAL INTERVENTION: What percentage of participants were at risk, as measured by one or more of the following criteria:
  • emotional disability label,
  • placed in an alternative school/classroom,
  • non-responsive to Tiers 1 and 2, or
  • designation of severe problem behaviors on a validated scale or through observation?

What were the background, experience, training, and ongoing support of the instructors or interventionists?
The ROOTS intervention was delivered by district employees and interventionists hired specifically for the efficacy trial. The majority of interventionists (93.5%) identified as female (93.5%) and White (76.1%), with 12.0% identifying as Hispanic. The remaining 11.9% identified as another race/ethnicity or declined to respond. Almost all interventionists (92.3%) had previous experience providing small group instruction, and 60.5% had a bachelor’s degree or higher. About half of interventionists (56.5%) had taken an algebra course at the college or graduate level. On average, interventionists had 10.4 years of teaching experience (SD p 8.6), and 22.0% had a current teaching license or certification. The ROOTS interventionists participated in two 5-hr professional development workshops that were delivered by project staff with a background in mathematics education, including one of the curriculum developers. The initial workshop focused on mathematics content covered through Lesson 25, effective instructional practices (e.g., eliciting group and individual responses, providing academic feedback), and strategies for small group management (e.g., instructional pacing, setting group expectations). The second workshop covered content from Lesson 26 to 50 and reviewed instructional and management strategies. During each workshop, project staff modeled lesson delivery and provided time for interventionists to practice lessons and receive feedback on their use of instructional practices. All interventionists also received between two and four coaching visits from ROOTS coaches during intervention implementation to boost implementation fidelity and enhance instructional quality. The coaching visits consisted of direct observations of lesson delivery followed by feedback on instructional quality (e.g., use of effective instructional practices and group management strategies) and fidelity of intervention implementation (e.g., correctly using mathematical models, following the teacher scripting).

Describe when and how fidelity of treatment information was obtained.
Fidelity of ROOTS implementation was measured via direct observations by trained research staff. Each ROOTS group was observed three times during the course of the intervention. On a 4-point scale (4 = all, 3 = most, 2 = some, 1 = none), observers rated the extent to which the interventionist (a) met the lesson’s instructional objectives, (b) followed the provided teacher scripting, and (c) used the prescribed mathematical models for that lesson. Observers also recorded whether the interventionist taught the number of activities prescribed in the lesson.

What were the results on the fidelity-of-treatment implementation measure?
Interventionists were observed to meet instructional objectives (M = 3.49, SD = 0.69), follow scripting (M = 3.31, SD = 0.75), and use prescribed models (M = 3.61, SD = 0.64). Interventionists also taught the majority of prescribed activities (M = 4.14 out of 5 activities per lesson, SD = 0.77). Interclass correlation coefficients (ICCs) for these fidelity ratings across observers were as follows: .82 for number of activities taught, .70 for meeting instructional objectives, .75 for following teacher scripting, and .70 for using prescribed mathematical models. According to guidelines proposed by Landis and Koch (1977), these ICCs indicate substantial agreement across observers. There were no differences in ICCs by group size.

Was the fidelity measure also used in control classrooms?
No. The ROOTS intervention occurred outside of and in addition to core mathematics instruction. To document the instructional practices and mathematics content employed in the control condition, research staff administered two surveys and conducted one direct observation of core mathematics instruction during the intervention time period. No evidence of treatment diffusion or contamination of ROOTS instruction was found in the core mathematics instructional settings.

Measures and Results

Measures Targeted : Full Bobble
Measures Broader : Full Bobble

Study measures are classified as targeted, broader, or administrative data according to the following definitions:

  • Targeted measures
    Assess outcomes, such as competencies or skills that the program was directly targeted to improve.
    • In the academic domain, targeted measures typically are not the very items taught but rather novel items structured similarly to the content addressed in the program. For example, if a program taught word-attack skills, a targeted measure would be decoding of pseudo words. If a program taught comprehension of cause-effect passages, a targeted measure would be answering questions about cause-effect passages structured similarly to those used during intervention, but not including the very passages used for intervention.
    • In the behavioral domain, targeted measures evaluate aspects of external or internal behavior the program was directly targeted to improve and are operationally defined.
  • Broader measures
    Assess outcomes that are related to the competencies or skills targeted by the program but not directly taught in the program.
    • In the academic domain, if a program taught word-level reading skill, a broader measure would be answering questions about passages the student reads. If a program taught calculation skill, a broader measure would be solving word problems that require the same kinds of calculation skill taught in the program.
    • In the behavioral domain, if a program taught a specific skill like on-task behavior in one classroom, a broader measure would be academic performance in that setting or on-task behavior in another setting.
  • Administrative data measures apply only to behavioral intervention tools and are measures such as office discipline referrals (ODRs) and graduation rates which do not have psychometric properties as do other, more traditional targeted or broader measures.

For any substantively (e.g., effect size ≥ 0.25 for pretest or demographic differences) or statistically significant (e.g., p < 0.05) pretest differences, please describe the extent to which these differences are related to the impact of the treatment. For example, if analyses were conducted to determine that outcomes from this study are due to the intervention and not pretest characteristics, please describe the results of those analyses here.
Please explain any missing data or instances of measures with incomplete pre- or post-test data.
If you have excluded a variable or data that are reported in the study being submitted, explain the rationale for exclusion:
SAT 10 and SESAT were not administered pre and post and were used to investigate secondary research questions (e.g. closing the achievement gap with not-at risk peers).
Describe the analyses used to determine whether the intervention produced changes in student outcomes:
We assessed intervention effects on each of the primary outcomes with a mixed model (multilevel) time × condition analysis (Murray, 1998) designed to account for students partially nested within small groups (Baldwin, Bauer, Stice, & Rohde, 2011; Bauer, Sterba, & Hallfors, 2008).
