US test scores reveal that 2 of every 3 mid­dle school stu­dents are not achiev­ing pro­fi­cien­cy in 8th grade math.

Fig­ure 1 address­es this ques­tion. But why does this seem to be an intractable prob­lem? Cog­ni­tive sci­ence based research, sum­ma­rized below, helps to answer this question.

Peer reviewed, ran­dom­ized, con­trolled research shows sig­nif­i­cant increas­es in both achieve­ment and pos­i­tive atti­tudes regard­ing study of math­e­mat­ics. The main TEM site exhibits these data.

Dis­cus­sion

Most sub-pro­fi­cient 8th grade stu­dents will fail stan­dard 9th grade alge­bra and many will leave school. Even with “cred­it recov­ery” class­work that can lead to a high school diplo­ma, few of these stu­dents will suc­ceed in alge­bra or have ade­quate prepa­ra­tion for post-sec­ondary tech­ni­cal stud­ies that could lead to well-pay­ing employment.

Black and His­pan­ic stu­dents, pro­por­tion­al­ly, are the most vul­ner­a­ble, fol­lowed close­ly by oth­er minori­ties. Fifty six per­cent of white stu­dents achieve pro­fi­cien­cy or higher.

 

Black-White math achievement gap: 1990–2019

Tra­jec­to­ries reveal near­ly par­al­lel paths, except recent­ly as Black scores decline more than those of Whites. These remark­ably sim­i­lar patterns—just at dif­fer­ent achieve­ment levels—seem to sug­gest sys­temic nation­wide trends in capac­i­ty of instruc­tion­al resources to engage students—as if indexed at dif­fer­ent lev­els by soci­etal fac­tors. Fig. 2

Conditions of Achievement

Academic handicap: cognitive science perspective

Bar­ri­ers to learn­ing: a social-emo­tion­al-cog­ni­tive view.

Abil­i­ty to con­cen­trate varies with lev­el of social-eco­nom­ic sta­tus; as SES declines, wor­ries about life cir­cum­stances, and stress, tend to increase—thus ham­per­ing exec­u­tive func­tions which reg­u­late
atten­tion. Fig. 3.

As stress increas­es, so, too, do phys­i­cal and psy­cho­log­i­cal dis­com­fort, fur­ther dis­tract­ing the mind, dimin­ish­ing exec­u­tive func­tions and abil­i­ty to concentrate—again, feed­ing back to, and ampli­fy­ing, inter­nal stress, thus debil­i­tat­ing selec­tive atten­tion need­ed for achieve­ment. Where dai­ly class­room require­ments for clear focus and mind­ful prac­tice are imposed—but feel unten­able to the student—the stress cycle is fur­ther ampli­fied, often result­ing in fur­ther decreas­ing inter­est, oppo­si­tion­al behav­ior and/or con­flict with author­i­ties, feed­ing back to, and adding to, stress. In the world of neu­ro­science, this is referred to as a (down­ward spi­ral­ing) vicious cycle.

Con­trol orientation—internal vs. external—and motivation.

High­ly stressed stu­dents tend to lack a sense of con­trol of life events. In the class­room where clear, ded­i­cat­ed con­cen­tra­tion is essen­tial to mas­tery and cop­ing chal­lenges are high, oppor­tu­ni­ties for per­ceived con­trol (of one’s learn­ing) are often lim­it­ed. These com­pound­ing con­di­tions fur­ther com­pro­mise exec­u­tive func­tions, inter­fer­ing with access to innate cog­ni­tive poten­tial and con­tribut­ing fur­ther to stress. Moti­va­tion to attempt assigned work is weak­ened.

The dire con­se­quence of these inter­nal dynam­ics is that hope­ful­ness is under­mined with with­er­ing effects on will­ing­ness to exert effort. Fig. 4. Accord­ing to the NAEP long term trend results, effec­tive­ly, this con­se­quence screens 2/3 of US stu­dents from post-sec­ondary tech­ni­cal train­ing and well-pay­ing tech­ni­cal employ­ment opportunities.

Increasing leverage in the mathematics classroom

Con­sid­er­ing all that com­pro­mis­es dis­ad­van­taged stu­dents’ exec­u­tive func­tions, com­pen­sato­ry advan­tages are needed—especially in mathematics—that can restore cog­ni­tive focus, abil­i­ty to suc­ceed and the moti­va­tion to do so that follows.

To help dis­tract­ed stu­dents suc­ceed they must be engaged—and feel­ing successful—from day 1 and through­out a grad­ing peri­od in rig­or­ous stan­dards based math­e­mat­i­cal activ­i­ty. Mid­dle school math teach­ers know the chal­lenge of gen­er­at­ing this class­room spirit.

To estab­lish inter­est that sup­ports engage­ment, instruc­tion that is stu­dent-cen­tered and peer-inter­ac­tive while keep­ing to the bound­aries of stan­dard math pre­scrip­tions shows great promise—especially so if stu­dents can dynam­i­cal­ly oper­ate math­e­mat­i­cal tools to gen­er­ate and apply les­son con­tent to solve prob­lems, while help­ing one anoth­er in doing so.

The goal of this instruc­tion­al approach is to sup­port stu­dents in becom­ing self-deter­mined learn­ers. The illus­tra­tion below depicts a scene in which stu­dents of The Expert Math­e­mati­cian are engaged in this way. TEM maps well onto Self-deter­mi­na­tion The­o­ry that iden­ti­fies 3 innate psy­cho­log­i­cal needs that are uni­ver­sal across humanity—and, when sat­is­fied, sup­port feel­ings of well-being and enthu­si­asm for life. In the class­room, this trans­lates to clear think­ing, har­mo­nious rela­tions, focus and moti­va­tion. The real sense that “we are being suc­cess­ful together”.

 The 3 dimen­sions of SDT are: gen­uine sense of com­pe­tence that indi­vid­u­als main­ly gen­er­ate for them­selves; and also relat­ed­ness.

Strug­gling math stu­dents rarely if ever feel com­pe­tent in grade lev­el math­e­mat­i­cal activ­i­ties. Yet, when they are giv­en con­trol of a for­mal math­e­mat­ics gen­er­a­tor, with a peer read­ing instruc­tions to gen­er­ate and oper­ate, in real time, a math­e­mat­i­cal expres­sion, a sense of com­pe­tence quick­ly aris­es. There is no bet­ter math util­i­ty than Logo for doing this (more infor­ma­tion on the main site). Light acknowl­edge­ment by the teacher, “Yes, you did that; can you explain how you got this result?” Teach­ers will fol­low up with a lit­tle lite facil­i­ta­tion as need­ed to help stu­dents fill in con­cep­tu­al links.

How can stu­dents feel autonomous when lessons are pre­scribed? Just as we do not per­son­al­ly build the vehi­cle we dri­ve to work—we do oper­ate it; and if we are able to do so safe­ly get­ting to the next des­ti­na­tion, we can feel autonomous­ly com­pe­tent. This is true for use of any tool. Logo’s gen­er­a­tive prop­er­ty sup­ports excel­lent acces­si­bil­i­ty to the nuances and strict sub­tleties of math­e­mat­ics, dis­tin­guish­ing it from any oth­er math­e­mat­i­cal tool. Logo enables learn­ers to feel a gen­uine sense of auton­o­my as they gen­er­ate and oper­ate the essen­tial expres­sions of each math­e­mat­i­cal lesson.

This is the essen­tial fab­ric of TEM. Stu­dents prac­tic­ing col­lab­o­ra­tive skills as they study in a dynam­ic, mutu­al­ly com­ple­men­tary rela­tion­ship, sat­is­fy a basic need for pro­vid­ing, and receiv­ing, assis­tance in chal­leng­ing work. Stu­dents switch roles on alter­nate days, pro­vid­ing oppor­tu­ni­ties for each to oper­ate math­e­mat­i­cal­ly with for­mal math­e­mat­i­cal log­ic using Logo, then alter­nate­ly con­vey­ing instruc­tions to the key­board­er and writ­ing up math­e­mat­i­cal results. There is a deep the­o­ry of inter­de­pen­dence in social relations.
What does it take to achieve proficiency in 8th grade math?

Min­i­mal­ly, math­e­mat­ics con­tent must be appro­pri­ate. TEM’s con­tent aligns well with the NCT­M’s mid­dle school Prin­ci­ples and Stan­dards for School Math­e­mat­ics. Equal­ly impor­tant, a stu­dent must be suf­fi­cient­ly inter­est­ed in the sub­ject to engage and per­sist to proficiency.

Giv­en suf­fi­cient interest—whether the inter­est is intrin­sic or a result of persuasion—barriers to achieve­ment must feel sur­mount­able. Many stu­dents arrive in mid­dle school inad­e­quate­ly pre­pared for increas­ing­ly high­er lev­el math—and not hope­ful that sus­tained effort could bring suc­cess. Many of these stu­dents fear being fur­ther hum­bled by what they per­ceive as a con­stant stream of con­cepts and for­mal log­ic that they can­not understand.

Thus for the 85% of Black stu­dents and 78% of His­pan­ics who top out at Basic or Below Basic in 8th grade math, nation­al­ly, a unique mix of instruc­tion­al resources is need­ed to sup­port them to high­er achievement.

The Expert Math­e­mati­cian mid­dle school math­e­mat­ics cur­ricu­lum has shown promise in meet­ing this daunt­ing chal­lenge. Designed to max­i­mize inter­est, TEM incor­po­rates sev­er­al fea­tures that nat­u­ral­ly acti­vate interest—while also mak­ing acces­si­ble the com­plex nuances and intri­ca­cies of for­mal math­e­mat­i­cal log­ic. These fea­tures are a more read­able lit­er­ary reg­is­ter, col­lab­o­ra­tive learn­ing, and a com­put­er math util­i­ty that pro­vides a gen­er­a­tive learn­ing advan­tage.

The math­e­mat­ics micro­cul­ture. Learn­ing the tools and terms and prac­tices of the microculture.

The Expert Math­e­mati­cian pro­gram was devel­oped as an aca­d­e­m­ic chal­lenge inter­ven­tion that inte­grates a set of rel­e­vant and well-estab­lished the­o­ries of learn­ing and teach­ing, with cus­tomized les­son media, that com­bine to increase oppor­tu­ni­ties for both teach­ers and stu­dents to achieve improved out­comes. Con­duct­ed as designed, TEM enhances authen­tic con­fi­dence of stu­dents and teach­ers,  trans­lat­ing to moti­va­tion, engage­ment and learning.

Stu­dents with 6th grade read­ing skills should be able to under­stand les­son instruc­tions. One impor­tant advan­tage of stu­dent-cen­tered learn­ing is that stu­dents have some con­trol of les­son pac­ing. This fea­ture enables the learn­er to pause as need­ed to grasp a con­cept, before dash­ing on—an added ben­e­fit in deci­pher­ing tech­ni­cal lit­er­a­ture. Respect­ing this need of dis­ad­van­taged stu­dents is important—not to let them drift off too long, but acknowl­edg­ing that many of these stu­dents have nev­er under­stood some log­i­cal or seman­tic terms that a teacher might take for grant­ed. So stu­dents seem­ing “adrift” may sim­ply need more time to process a les­son ele­ment in terms of their exist­ing knowl­edge. They should be encour­aged to “give it your best think­ing,” but also know that the teacher will be around to help with a need­ed clarification.

Work­ing with a peer and with Logo and per­haps a lit­tle coach­ing, they can fill them in.

Prepar­ing to con­duct class. Teach­ers must active­ly work through lessons before assign­ing them to stu­dents. Les­son prepa­ra­tion is impor­tant for two reasons:

  1. Aware­ness of les­son con­tent and objec­tives, so any con­fu­sion can be con­fi­dent­ly facil­i­tat­ed to clarity.
  2. Readi­ness to raise inter­est­ing ques­tions relat­ed to the les­son content—such as, “if you change this con­stant (or vari­able input), what is the math­e­mat­i­cal result?” Then (gen­tly prob­ing, while expect­ing to coach or nudge with a hint), “Can you see why you got that result?” Fol­low­ing up with a brief inter­ven­tion, draw­ing from rehearsed Big Ideas in math­e­mat­ics, can deep­en stu­dents’ under­stand­ing of a con­cept and—importantly—help them to make con­nec­tions between the present item of study and pri­or con­cepts. Big Ideas in math­e­mat­ics are fur­ther dis­cussed with sources in the main site page and the down­load­able Guide­lines for Teach­ing TEM, fol­low­ing sign-in below.

This is all prob­lem-solv­ing”, one suc­cess­ful teacher of TEM, com­ment­ed. But it’s engag­ing and with teacher’s light­heart­ed sup­port and rein­force­ment of stu­dents’ use of col­lab­o­ra­tive skills (each stu­dent doing their part; and—if needed—use of reward tokens with week­ly draw­ing for small prizes), stu­dents will increas­ing­ly make the effort and they will learn. Using Logo has its own rewards: as not­ed, stu­dents can feel math­e­mat­i­cal­ly com­pe­tent like they nev­er have previously.

Sched­ul­ing class­es: Peri­od or block? Orga­ni­za­tion­al­ly, there’s a lot going on in The Expert Math­e­mati­cian learn­ing com­mu­ni­ty. Stu­dents need enough time to pick up their mate­ri­als, get set­tled, and begin work. Time should be allot­ted for stu­dents to write out, work, and turn in a cou­ple of cal­cu­la­tion prob­lems before start­ing on the day’s les­son. To estab­lish momen­tum, allow­ing stu­dents enough time to active­ly engage their les­son is impor­tant. A sin­gle 45–50 minute class peri­od is scarce­ly enough time for thought­ful engage­ment and teacher sup­port. Nine­ty minute block sched­ul­ing is strong­ly encouraged.

Back­ground the­o­ries at work. Ped­a­gogy, the­o­ry, social-cul­tur­al tools ZPD and “tools” should be lead­ing facil­i­ta­tive process (con­trast with con­tent) Fine-tun­ing the col­lab­o­ra­tive peer inter­de­pen­dence part will car­ry the chal­leng­ing days. Gen­tle reminders that, “we are in this togeth­er; we help each oth­er suc­ceed” (cou­pled with check­list rein­force­ment) will be reas­sur­ing. And, you will see Vygot­sky’s social-cog­ni­tive the­o­ry in prac­tice. Many stu­dents under­stand this (intu­itive­ly) from a team sport; that’s one micro­cul­ture. Now they are prac­tic­ing bring­ing these skills into the cul­ture of math­e­mat­i­cal prac­tice that will be use­ful in the world of work.

Of dis­ad­van­taged stu­dents you are ask­ing a lot, so it’s impor­tant to be direc­tive in get­ting set up and start­ing lessons, but then light­heart­ed and patient in cul­ti­vat­ing peer work habits and the “growth mind­set” as stu­dents process math­e­mat­i­cal ideas.

Teach­ers also check in briefly with stu­dents to deter­mine their com­pre­hen­sion, facil­i­tat­ing stu­dents to cor­rect under­stand­ing of les­son points, as needed.

Cal­cu­la­tion skills. Stu­dents jump right into lessons. When rou­tines have been estab­lished, they begin to prac­tice com­pu­ta­tion­al skills. Stu­dents should have some choice in which skills to prac­tice, but they should try to keep their choic­es con­sis­tent with con­cept lessons. They should acti­vate and oper­ate a game, write out the prob­lem on a half sheet of paper and do the cal­cu­la­tion on paper to deduce the answer. The answer is then keyed in to check accu­ra­cy. Although stu­dents are work­ing togeth­er, they should each do two dif­fer­ent prob­lems and hand them in. Cal­cu­la­tion pro­fi­cien­cy is impor­tant but should not delay work­ing through the lessons to learn and apply con­cepts to solve prob­lems. This is a major strength of the pro­gram. If ses­sions are lim­it­ed to 40 min­utes, get­ting set­tled, pick­ing up their fold­er, get­ting start­ed need to hap­pen fast. Nine­ty minute block sched­ul­ing works better.

Fol­low­ing is a still-life cameo of stu­dents at work and teacher rein­forc­ing skills practice.

Looking Ahead

Fourth grade achieve­ment of minor­i­ty and low income stu­dents sig­nif­i­cant­ly lags white achieve­ment and declines fur­ther by grade 8 on the NAEP.

Mid­dle school is real­ly the last chance to help Basic and Below Basic stu­dents to recov­er con­fi­dence and gen­er­ate the foun­da­tions need­ed to suc­ceed at least in alge­bra 1 prin­ci­ples. Stu­dents who feel com­pe­tent at that lev­el will be able to car­ry for­ward their growth mind­set in math­e­mat­ics to tech­ni­cal train­ing or OJT appren­tic­ing, pos­si­bly lat­er in their sec­ondary stud­ies or fol­low­ing high school graduation.
