Pirate Math Individual Tutoring
Study: Fuchs et al. (2009)
Summary
Pirate Math Individual Tutoring is a tutoring program for remediating the calculation and wordproblem deficits and for promoting the algebraic cognition of thirdgrade students atrisk or with identified math disability. The program is based on schemabroadening instruction, with which students learn to think about word problems in terms of problem types and learn to classify word problems in terms of those problem types, even when the problems incorporate irrelevant information or involve money or incorporate relevant information in pictures, charts, or figures or combine problem types so that problems require 2step solutions. Students learn to represent the structure of each type of word problem using an algebraic equation and learn to solve those algebraic equations. The program is organized in terms of 4 units. The first unit teaches skills that are foundational skills to word problems (counting strategies for answering math facts, 2step procedural calculations, solving algebraic equations, and checking wordproblem solutions). Then, each of the next 3 units focuses on one problem type, with systematic cumulative review embedded throughout the units. The three problem types are two problems (where two quantities are combined to make a new amount), difference problems (where two quantities are compared), and change problems (where an event occurs to increase or decrease an initial amount). Sessions occur 3 times per week for 2030 minutes per sessions across 16 weeks on a onetoone basis. Tutors can be certified or noncertified teachers, each of whom is trained in a 1day session and then supervised with biweekly meetings. Pirate Math has been shown to improve outcomes on math fact fluency, procedural computational skill, wordproblem skill, and algebra skill.

Participants
 Describe how students were selected to participate in the study:
 The study was conducted at two sites, both large urban school districts. Houston was distal and Nashville was proximal to the developers of the tutoring protocols. Thirdgrade students (n=924) were screened for inclusion in 63 classrooms in 18 schools. Seven schools and 23 classrooms were in Houston; 11 schools and 40 classrooms were in Nashville. Because tutoring focused on NCs or on WPs, we included students with low performance on a calculations screening measure or a WP screening measure. (Screening occurred in stepwise fashion; so students did not receive every measure.) The criterion applied for low performance on the calculations measure was < the 26th percentile. The criterion applied to the 5item wordproblem measure was a score of 0 or 1. (See measures for description of the screening measures.) All 924 students were administered the calculations measure; 302 (33%) scored < the 26th percentile. We administered the 5item WP screener to 598 students; 170 (28%) scored 0 or 1. Of the 598 students who took the calculations and the WP screening measures, 291 (49%) did not meet the inclusion criterion on either measure; 67 (11%) met only the WP criterion; 137 (23%) met only the calculations criterion; and 103 (17%) met both criteria. The 307 students who met either or both criteria were eligible for further screening on a reading and an abbreviated IQ measure. We excluded students who scored between the 25th and 40th percentiles in reading and students with a Tscore below 30 on both IQ subtests. Students scoring < the 26th percentile on the reading measure were classified as having math and reading difficulty (MDRD). Those scoring > 39th percentile were classified as math difficulty alone (MD). Two hundred and two students took all measures. Of these students, 32 (16%) were excluded due to reading scores between the 25th and 40th percentiles; two students were excluded due to low IQ scores; and one student was excluded for both reasons. Thus, 165 students were eligible for tutoring. However, 162 students comprised the actual assignment sample because three students who met all criteria were accidentally not included in the assignment sample. Blocking on site, type of screening difficulty (WPs, calculations, or both), and difficulty status (MD or MDRD), we randomly assigned students to one of three treatment conditions (NC tutoring, WP tutoring, or control). So, the composition of each treatment group was similar in terms of the three blocking variables. Of the 162 students, 13 (8%) moved after randomization but prior to the onset of tutoring, 7 (4%) moved during the school year, 5 (3%) were excluded by parents or schools prior to the onset of tutoring, and 4 (2%) were withdrawn by parents or schools during the school year, leaving 133 who were evaluated at posttest.
 Describe how students were identified as being at risk for academic failure (AI) or as having emotional or behavioral difficulties (BI):

 What were the background, experience, training, and ongoing support of the instructors or interventionists?
 The tutors were parttime or fulltime employees of the research project. In Houston, tutors were not certified teachers, and they were drawn from the community. Each tutor had an undergraduate degree, but the degrees were not necessarily in educationrelated fields. In Nashville, tutors were graduate students across departments at Vanderbilt University (3 were certified teachers; 9 were not). The graduate students were not necessarily in education programs. Tutors were trained as follows: 1 session of instruction; practice implementing the procedures alone and with each other during the subsequent week; a practice session conducted with a supervisor who provides corrective feedback; tutors studying (not reading) scripts; and meeting among tutors and the supervisor every 23 weeks to address problems or questions as they arise.
 Describe when and how fidelity of treatment information was obtained.
 Every tutoring session was audiotaped. Four research assistants independently listened to tapes while completing a checklist to identify the percentage of essential points in that lesson. We sampled 16.8 of tapes such that treatments, tutors, and lesson types at each site were examined comparably.
 What were the results on the fidelityoftreatment implementation measure?
 At the site where the protocols had been developed (Nashville), the mean percentage of points addressed was 98.1 (SD=2.06) for number combinations (competing) tutoring and 98.4 (SD=2.79) for WP (Pirate Math) tutoring. In Houston, the mean percentage of points addressed was 99.5 (SD=0.47) for number combinations (competing) tutoring and 99.2 (SD=0.68) for WP (Pirate Math) tutoring.
Tutors also recorded the duration of each session. In Nashville, tutoring min averaged 1032 (SD=85.08) for number combinations (competing) tutoring and 997 (SD=130.25) for WP (Pirate Math) tutoring. In Houston, total tutoring min averaged 1155 (SD=130.09) for number combinations (competing) tutoring and 1158 (SD=184.69) for WP (Pirate Math) tutoring. Analysis of variance revealed a significant effect for site, F(1,82)=15.68, p<.001, with more time in Houston than Nashville. More pertinently, the effect for treatment condition was not significant, F(1,82)=0.18, p=.669; neither was the interaction between treatment and site, F(1,82)=0.27, p =.603.
 Was the fidelity measure also used in control classrooms?
Measures and Results
Measures Broader :
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 wordattack skills, a targeted measure would be decoding of pseudo words. If a program taught comprehension of causeeffect passages, a targeted measure would be answering questions about causeeffect 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 wordlevel 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 ontask behavior in one classroom, a broader measure would be academic performance in that setting or ontask 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 posttest data.
 If you have excluded a variable or data that are reported in the study being submitted, explain the rationale for exclusion:
 Describe the analyses used to determine whether the intervention produced changes in student outcomes:
 We conducted distributional exploration of each measure via statistical (e.g., skewness, kurtosis) and graphical (e.g., box plots, stem and leaf plots) means. Generally, the standardized variables were normally distributed at both time points. However, Vanderbilt Story Problems was positively skewed and kurtotic at both time points, and Find X was negatively skewed at pretest and bimodal at posttest. In the case of Vanderbilt Story Problems, a squareroot transformation was completed, which improved distribution; however, because results for the original and the transformed variables were similar, results of the original variable are presented for ease of interpretation. Similarly, for Find X, logistic analyses (dichotomizing scores into high and low) yielded similar results as the original variables; so we retained the original form. Number Sentences at pretest and procedural computations at posttest also showed some skewness, but transformations did not generally improve distributions. Age was unrelated to pre or posttest performance. Also, tutoring time was unrelated to all but two outcomes, and in this case, the relation was small and did not interact with other effects or change conclusions. Therefore, these variables are not reported. The factors of interest were difficulty status (MD vs. MDRD), site (Houston vs. Nashville), and tutoring condition (number combinations, i.e., competing condition, tutoring vs. WP, i.e., Pirate Math, tutoring vs. control).
