elegantlion Posted April 30, 2008 Share Posted April 30, 2008 I received a book "Modern school mathematics Structure & Method, course 2 new edition". It is the teacher's edition. What grade level would this book be for? The isbn is 039513773x copyright 1972. All of these old textbooks have me confused, intrigued, but confused.

Kimber Posted April 30, 2008 Share Posted April 30, 2008 I believe you have Algebra 2. Now you just have to find the solutions manual (if there are any out there now) and the student's edition. Quote Link to comment Share on other sites More sharing options...

forty-two Posted April 30, 2008 Share Posted April 30, 2008 I think it is a middle school textbook, probably grade 8. I did a google search and found a study comparing the difficulty of probability problems in math books of various eras, from New Math onward. It stated that Modern School Mathematics: Structure and Method was considered one of the most popular middle school texts of the New Math period. (They also include Saxon in their comparisons, as part of the Problem Solving, 1984-1993, group, just as a point of interest.) I imagine it was meant to lead into the algebra Structure and Method books. Quote Link to comment Share on other sites More sharing options...

elegantlion Posted April 30, 2008 Author Share Posted April 30, 2008 Thanks so much, both of you. Kimber, I was hoping it was Algebra 2 when I ordered it. I got it from paperbackswap so it was basically free. I did think it looked too easy for Alg 2, IOW I understood it :001_smile:. Forty-two thanks for linking the report, I'll have to check that out. I did find an inexpensive student text I may just go ahead and order. That way we could jump into this book before heading straight into the algebra. Thank you, thank you.

Kimber Posted April 30, 2008 Share Posted April 30, 2008 You are so right! I apologize elegantlion! I tend to skim when I read. I only caught Structure and Method Book 2. I am sooo sorry for steering you wrong. Good Luck finding the right one. Quote Link to comment Share on other sites More sharing options...

Kimber Posted April 30, 2008 Share Posted April 30, 2008 Paula, Do these books introduce proofs at this level? Quote Link to comment Share on other sites More sharing options...

elegantlion Posted April 30, 2008 Author Share Posted April 30, 2008 Okay, I plead total ignorance of all things higher math. How do I tell about the proofs? Quote Link to comment Share on other sites More sharing options...

forty-two Posted April 30, 2008 Share Posted April 30, 2008 I've been reading over the study, and I'm not sure what I think of it. The authors are using constructivist standards (straight from a '98 NCTM publication) to judge the cognitive load of each problem, and so naturally the only constructivist series has far more problems at high cognitive loads (which the study considers to be good) than all the rest. Said series, Connected Mathematics, received an F from Mathematically Correct for its 7th grade text (though it did receive its only good marks for the section that most pertains to probability). I'm deeply skeptical about the efficacy of constructivist math, and, as the authors of this study have the superiority of contructivist standards as one of their underlying assumptions, I'm skeptical about their results.

Kimber Posted April 30, 2008 Share Posted April 30, 2008 Once again, I skimmed it. And I couldn't get the jest of what they were trying to prove too well. But it didn't seem overly positive on the new math. Kimberly But thank you immensely for the link. I've been looking for New Math type pre-algebra books and evidently these are the ones I was searching for. Quote Link to comment Share on other sites More sharing options...

Kimber Posted April 30, 2008 Share Posted April 30, 2008 I am assuming that they don't do proofs as that level. Proofs basically mean the students must explain or justify their mathematical operation. For instance, if they multiply 2 times everything in the parentheses then must write down next to that operation that they can do this because of the distributive law of multiplication. I am wondering, however, whether or not the book you have found asks students to give an example of terms such as the distributive law of multiplication. Are they expected to memorize terms like addend, subtrahend, dividend, etc.... Basically, are they required to write out or give examples of simple equations that demonstrate mathematical laws and be able to write definitions for them. Like these for example Commutative law of addition: m + n = n + m . A sum isnâ€™t changed at rearrangement of its addends. Commutative law of multiplication: m Â· n = n Â· m . A product isnâ€™t changed at rearrangement of its factors. Associative law of addition: ( m + n ) + k = m + ( n + k ) = m + n + k . A sum doesnâ€™t depend on grouping of its addends. Associative law of multiplication: ( m Â· n ) Â· k = m Â· ( n Â· k ) = m Â· n Â· k . A product doesnâ€™t depend on grouping of its factors. Distributive law of multiplication over addition: ( m + n ) Â· k = m Â· k + n Â· k . This law expands the rules of operations with brackets (see the previous section). Modern day middle school books use the terms but don't require students to memorize them. At least as far I know. Foersters may be one that does.
