Statement of the Problem
  • Forty-three percent of African American high
    school students failed the Texas Assessment of
    Knowledge and Skills (TAKS) Exit-Level
    Mathematics Test. The data table showed the
    failure rate was higher among African American
    students than any other ethnic groups (TEA,
    2005).

5
Purpose of the Study
  • The purpose of this study was to investigate
    the impact that high school mathematics scores
    and courses had on the Mathematics TAKS
    Exit-Level performance of African American
    students. Some middle school counselors were
    surveyed to investigate factors that contributed
    to African American students passing the
    Mathematics TAKS Exit-Level Test.

6
Purpose of the Study
  • The results of this study may be helpful to
  • school administrators, teachers, and
  • parents. The results will help to give
  • needed attention to students in terms of
  • proper placement in mathematics courses
  • along with support in the learning process.

30
Interview Support
  • District policy requires standardized test
  • scores (primarily Iowa and TAKS) to be
  • used with grades.
  • District guidelines direct the placement of
  • students in Algebra in the 8th grade.
  • I follow the same schedule that the
  • students from the home school enter
  • with.

31
Related Literature Support
  • In Principles and Standards for School
  • Mathematics, the National Council of Teachers of
  • Mathematics (NCTM, 2000) identified algebra as
  • one of the central themes in K-12 mathematics.
  • Many educators perceive algebra as the gateway
  • to higher mathematics, and many state
  • graduation requirements include at least 1 year
    of
  • algebra (McCoy, 2005).

32
Major Findings Qualitative Question 3b
  • When advising African American students for
  • mathematics placement, what is the most
  • important factor?

  • Teachers recommendation 4 25.00
  • Counselors recommendation 0 0.00
  • Family history 0 0.00
  • Due to less than total documented responses,
    percentages do not add up to 100.

33
Interview Support
  • The district has a matrix that we follow that
    guides us in
  • placing students in Algebra I as an 8th grader.
    We
  • examine previous grades and teacher
    recommendations to
  • determine placement in our AVID (college prep)
  • program.
  • Teacher recommendations are important but much
    less
  • reliable due to subjectivity.
  • I would consider the students desire for a
    challenge and
  • then speak with the teacher as well.
  • I follow the same schedule that the students
    from the
  • home school enter with.

  • Change entry level 3 18.75
  • Due to multiple responses, percentages do not
    add up to 100.

35
Interview Support
  • The Ethnic Disparity Gap is irrelevant when
    there are strong supportive homes. This is in
    consonance with the counselors claim that
    parental involvement has tremendous, effective
    influence on students success.

36
Related Literature Support
  • Much of the difference in school
  • achievement found between African
  • American students and others is due to
  • the effects of substantially different
  • school opportunities, and in particular,
  • greatly disparate access to high quality
  • teachers and teaching (Darling-Hammonds,
  • 2000).

38
Interview Support
  • Course selection or qualification for advanced
    classes is
  • the only time we meet to discuss placement.
    Districts
  • Track doesnt allow a student to enter in higher
    classes in
  • 8th grade unless enrolled in 7th grade
    mathematics.
  • I follow the same schedule that the students
    from the
  • home school enter with.
  • We tell students in the 6th grade when we let
    them
  • choose their courses about district mathematics
  • requirements. We tell them again at orientation
    night
  • during the first day of school. We tell them
    again at open

Related Literature Support
  • Working in an urban Missouri junior high school,
    investigators studied what happened when students
    of average mathematics achievement were assigned
    to an advanced eighth-grade pre-algebra class.
    They found that the achievement of accelerated
    average students was better than the achievement
    of similar students in previous years who had not
    taken accelerated mathematics (Burris, Heubert,
    Levin, 2006).

41
Related Literature Support
  • The average-achieving students in the high-track
  • classes enrolled in more advanced high school
  • mathematics courses than did students at similar
  • achievement levels from previous low-track
  • cohorts. The results of the studies are
    consistent with the
  • findings and demonstrated almost no growth among
  • students placed in low-track, remedial
    eighth-grade
  • classrooms, and the conclusions from a study
  • commissioned by the National Research Council
    that
  • documented strong negative effects of low-track
    classes
  • (Burris, Heubert, Levin, 2006).

45
Related Literature Support
  • A students path in middle school can shape his
    or
  • her course in high school, which affects success
  • in college and thereby determines a career path.
  • As we look at African Americans in the
  • workplace, our gaze is necessarily directed back
  • to their formative academic experiences in
  • middle school, high school and college, where the
  • track to their future success is first laid down
  • (Report Highlights Importance of Middle School
    Math, 2003).

46
Major Findings Qualitative Question 3h

47
Related Literature Support
  • African American students are twice as
  • likely to be placed in non-academic track
  • classes and remedial mathematics
  • classes. Placement in these classes
  • exposes students to a less challenging
  • curriculum and the least experienced
  • teachers (Rubin Noguera, 2004).

48
Related Literature Support
  • Berry (2003) stated that African American
  • students receive mathematics instruction
  • that is not consistent with mathematics
  • education reform furthermore, the
  • mathematics instruction that many African
  • American students receive is in opposition
  • to their culture styles and learning
  • preferences.

49
Related Literature Support
  • African American students take fewer
  • algebra and geometry courses than White
  • students and these courses are often
  • gate-keepers to science and mathematics
  • degrees and performance on standardized
  • examinations (Russell, 2005).

50
Major Findings Qualitative Question 3i
  • How do you rate the counseling department in
  • dealing with African American 8th grade
  • students in mathematics?
  • Rating Frequency Percent
  • Outstanding 1 6.25
  • Above average 6 37.50
  • Adequate 8 50.00
  • Poor 0 0.00
  • Due to total documented responses, percentages
    do not add up to 100.

51
Interview Support
  • We have a large group of student load and
  • we treat them all the same in placement
  • and do not single out one group. We speak
  • to all the same and with the same
  • information which to encourage them all.

52
Implications
  • Berry (2003) points outs that African American
    students
  • mathematics achievement levels are indicative of
    the
  • instruction that they receive. Data collected on
    teachers
  • instructional practices indicate differences
    between African
  • American students and their peers.
  • National Assessment of Educational Progress
    (NAEP) data suggest
  • that most African American students are not
    experiencing
  • instructional practices consistent with the
  • recommendations suggested by the National Council
    of
  • Teachers of Mathematics (NCTM), whereas more
    White
  • students are experiencing NCTM standards-based
  • instruction (Lubienski, 2001).

53
Implications
  • The power and influence of the middle-class,
  • affluent, and more privileged parents plays an
  • important role in deciding who will be in their
  • kids classes. More often than not, political
  • pressure from parents coupled with low
  • expectations for African Americans in the
  • classroom by teachers, counselors, and
  • administrators result in homogeneous tracks
  • and ability groups (Russell, 2005).

54
Implications
  • Tracking in American schools often contained a
    racial and
  • socioeconomic element. African American students
    were
  • more likely to be tracked in the vocational
    curriculum,
  • Hispanic students in the general curriculum, and
    Asian and
  • White students in academic or advanced placement
  • curricula. Essentially, the content, rigor, and
    teaching
  • strategies vary markedly among curricula
    programs,
  • although the course names in each program may
    often be
  • similar. It was also well documented that
    African American
  • and Hispanic boys were over-represented in
    special
  • education programs (Futrell Brown, 2000).

55
Implications
  • Ward (2008) pointed out that mathematics
    achievement
  • builds to increasing levels of complexity only
    when the base
  • is solid, and that base is formed from the
    earliest days of
  • elementary school. Too many elementary school
    teachers,
  • strong in other subjects and talented in
    connecting with
  • children, lack the mathematics background needed
    to
  • prepare students for algebra by the eighth grade.
  • Additional research based training, targeted at
    the specific
  • skills needed for effective algebra instruction,
    will be
  • critical and costly.

56
Implications
  • The existence of linear regression equations
  • may become one of the bases for remediation
  • efforts to assure that students pass the
  • mathematics high-stakes test. Administrators
  • and teachers may forestall problems associated
  • with the State of Texas requirement for
  • students to graduate from high school.

57
Recommendations for Further Study
  • A study should be conducted to involve
    representative samples from one or more districts
    in a similar study to determine if results can be
    duplicated.
  • A study should be conducted to involve another
    group of students (Whites, Hispanics, Asians,
    etc.) in a similar study.

58
Recommendations for Further Study
  • A study should be conducted to determine
    specific activities of the guidance and
    counseling department in the placement of
    students not only in mathematics but also in the
    different core areas of science, English and
    social studies.
  • A study should be conducted on the quality of
    mathematics instruction involved in the different
    tracks.

59
Recommendations for Further Study
  • A study should be conducted to predict the
    performance of African American students in the
    other core areas.
  • A quantitative study should be conducted with a
    large random sample of teachers and school
    counselors regarding the impact of high school
    mathematics curricula on the mathematics TAKS
    Exit-Level performance of students.

60
Recommendations for Further Study
  • A study should be conducted regarding remediation
    practices done by the school and the home in
    preparing students to succeed in the high-stakes
    tests given by the State of Texas, not only in
    mathematics but also in the other core areas.

61
Challenge Opportunity
  • Simply put, until African American students
    on the pre-college level are participating at the
    highest levels in more rigorous, challenging
    science and mathematics courses, the achievement
    gap will only become more pronounced. Although
    African Americans have increased their
    participation in the sciences within the last
    decade, it is important to note that these
    advances are still miniscule when compared to
    those of White students (Russell, 2005).

62
Challenge Opportunity
  • The attitudes and experiences of many school
    personnel
  • need to change, too. I have been on campuses and
    in
  • classrooms throughout the state, and it is
    consistent from
  • one end to the other certain students are seen
    as algebra-
  • ready, and certain students are not. Its no
    mystery Asian
  • and White students on one hand Latino, African
    American
  • and poor students of all ethnicities on the
    other. But they
  • are not ready. This is the common and perfectly
    honest
  • explanation. But it is our job to make them
    ready. It is work
  • we have chosen. It is our responsibility (Ward,
    2008).
