Supplemental Materials Needed: scientific calculator we recommend the TI-30X or TI-30XS because it will help you will fractions. COURSE DESCRIPTION Developing Mathematical Thinking MATD 0485: (4-4-0) A course designed to develop the skills, including reading and thinking, and the understanding needed for non-math, non-science majors who take MATH 1332, MATH 1333 and MATH Topics include: linear models, data interpretations including graphs and tables, percentage models, order of operations, logic of arguments, and an introduction to other models which may include exponential, logarithmic, quadratic and/or rational models. This course is not for college level credit.

2 COURSE RATIONALE: This is an alternative course to Elementary/Intermediate Algebra for students who are going on to one of these college-credit math courses: MATH 1332, College Math; MATH 1333, Math for Measurement; or MATH 1342, Elementary Statistics. Students who are mandated to take Developmental Math by the TSI rules may satisfy the TSI requirement by completing this course with a grade of C or better. Students who pass this course are not ready for MATH 1314, College Algebra, or MATH 1324, Math for Business and Economics. If your degree plan requires MATH 1314 (College Algebra) or MATH 1324 (Math for Business & Economics), then you will need to complete both MATD 0370 followed by MATD 0390 (lecture-based courses) or all 12 objectives of MATD 0421 (personalized curriculum, computer-based course). INSTRUCTIONAL METHODOLOGY: This course is taught in the classroom primarily as a lecture/discussion course. The course will have numerous group learning activities that are done in class. THE NATURE OF THIS COURSE: This class will be different in many ways from your other math classes. You are NOT expected to memorize a lot of information, memorize steps for working a particular type of problem, or work the same kind of problem over and over. We won t do as much with the algebra rules you have learned in your other math classes, but we will study some topics more deeply and learn to think about mathematical concepts and ideas differently. You may not have experienced this kind of learning before, and that can be a little daunting. However, students who haven t always enjoyed a typical algebra course usually enjoy the nature of this course since it is so different. EXPECTATIONS You are expected to struggle with some complicated ideas with classmates and on your own to make more meaningful connections and synthesize ideas. You are expected to work with real-world scenarios and data, which means the numbers, get messy. You are expected to talk with other students about your ideas and listen carefully to their ideas, so you can learn to think through all kinds of different math problems. You are expected to spend a lot of time thinking more deeply about mathematical ideas. You are expected to think through a problem and apply your knowledge to ones that you have never seen before. Course Objectives/Student Learning Outcomes: Upon successful completion of the course, students will be able to: 1. Use a variety of problem-solving strategies to solve multiple-step problems using arithmetic and fundamental level algebraic techniques. 2. Solve application problems that require careful reading and the selection of the relevant information from a more extensive set of given information.

3 3. Use the basic logical operators to draw logical conclusions. 4. Appropriately use order of operations to evaluate numerical expressions on a scientific calculator. 5. Read data tables and graphs, and use the information to answer questions such as percent change. 6. Produce graphs of linear and exponential functions by point-plotting over given domains. 7. Work percentage problems including developing exponential functions to reflect situations with a constant percentage of growth 8. Determine whether a set of data points or a verbal description models a linear or exponential function or does not model either. 9. Write equations to model linear and exponential data. These course objectives illustrate that this course in not an algebra course as are most developmental mathematics courses. It is a course about thinking and using mathematics. There is some algebra in the course, but algebra is not the predominant topic or the focus of the course. CLASS POLICIES HOMEWORK: In order to succeed in any math course you need to complete all assigned homework as soon as it is assigned. You are expected to record your work and keep a log of your problems in a readable format. You will enter your answers on MyMathLab and be sure to seek help for any problems that are not completely understood. It is your responsibility as a student to ask for and get help! Your experience with MyMathLab will depend on the effort you put into it. Because how you are thinking about the mathematics is just as important as getting the right answer, there are several questions in MyMathLab that model the language we expect to see on your written work. Rather than focusing on getting the "right answer", you will get the most benefit from your MyMathLab HW if you pay careful attention to the language used in the fill-in-the-blanks and multiple-choice items so you know how to explain processes and justify answers on your take-home quizzes and exams. QUIZZES: You will be expected to complete quizzes for this course, there are nine Take-Home Quizzes (paper and pencil). If you are absent and would like your Take-home Quiz to count as on time, or text a picture of it to me by the end of the day it is due. I will drop one Take-Home Quiz grade from your average to account for the occasional week when other life things come up. You will earn 100%, if you complete the quiz, on time, following all the directions and have only minor errors. You will earn an 85%, if you make more than one significant error and/or do not follow directions. You will earn a 50%, if you do not finish every problem on a take home quiz, have significant errors, and/or do not follow directions. If you do not turn in a take home quiz (quizzes are not accepted after midnight on the due date) you will earn 0. For students that want to earn all available points for quizzes, complete all questions following the directions and turn it in on time. If you need help on a problem be sure you ask for help before you turn in your quiz.

4 GROUP WORK AND PARTICIPATION: You are going to interact with each other quite a bit and talk to each other about math. There will be group activities every day in class. You are expected to be an active participant and contribute to the discussion of the problems on the group activities. Though you will be working with other students, everyone will record the work on their own paper. These will be your notes you will use to complete homework assignments, so you need to ask questions and make sure you understand the ideas in the activity. I know that some of you do not like to talk in class and others of you like to talk a lot. So, we will follow a couple of easy rules. We give everyone a chance to talk. We respond to whatever anyone says with respect. We are concerned here about concepts that will help you succeed in your college-level math courses and ultimately achieve your academic goals. You are all in the same boat; I expect that students in this class will support each other and be respectful when working together. PROJECT: There will be a project at the end of the semester which you will get details for then. It will involve statistical analysis. TESTS: There will be three exams given in class or in the Testing Center. There will be an optional fourth exam. It will be a retake of your lowest exam. If you choose to take the fourth exam it will replace your lowest of the three exam scores. No make-up exams will be given. If you miss an exam, that score will be a zero and you will not be allowed to replace that with the retake. There is no departmental final exam. If your first two exam grades are all below 50, you may be withdrawn for lack of progress. Missed Exam Policy: Do Not Miss Test Dates. If you have an emergency please contact me immediately. We might be able to work out an alternative setting. Missed tests will count as a 0 and if you have not contacted me you will probably be withdrawn from the course. Late Work Policy: Take home quizzes are not accepted late. Extensions for tests will not be administered unless you have extenuating circumstances that can be documented and contact me prior to the deadline or end of the test day. Homework is due the day after class, a penalty of 20% will apply for homework not completed by 11:59 Sunday each week. Attendance: Regular attendance is required. Being more than 10 minutes late will count as an absence. Cutting out early without prior notification will count as an absence. Leaving more than 10 minutes early will count as an absence, even with prior notification. Students who miss 4 or more classes may be withdrawn without warning. Tardiness is disruptive and rude, please be on time. If you do not participate in the group or learning activities, then you may be withdrawn from the course.

5 Cell Phones: Devices must be silent and put away during class, unless we are using them in for class activities. You cannot be fully engaged in the topic at hand if you are also engaged in your phone! Cell Phones seen during tests or quizzes will constitute cheating, result in a zero and a report to the Dean. Written work Instructions for work throughout the semester On the first or new page for each assignment include in the upper right hand corner: your first and last name, class days, class beginning time, Always include the section number you are working on and HW for homework. All turned in work is to be done in pencil or erasable pen. Box or circle your final answer. You must justify answers to problems unless it is fill in the blank. Answers should be given in complete sentences. Example HW Elton Doe TTh 2:30 1] 570/15=38 HW 1.1 The average household age was 38 years old in ACC Learning Labs provide free tutoring services to all ACC students currently enrolled in the course to be tutored. The tutor schedule for each Learning Lab may be found at: Deaftec videos on some algebra topics found at: For help setting up your ACCeID, ACC Gmail, or ACC Blackboard, see a Learning Lab Technician at any ACC Learning Lab GENERAL AND COLLEGE POLICIES Withdrawal Policy: It is the responsibility of each student to ensure that his or her name is removed from the roll if he or she decides to withdraw from the class. The instructor does, however, reserve the right to drop a student should he or they feel it is necessary. If a student decides to withdraw, he or she should also verify that the withdrawal is submitted before the Final Withdrawal Date. The student is also strongly encouraged to retain their copy of the withdrawal form for their records. Students who enroll for the third or subsequent time in a course taken since Fall 2002 may be charged a higher tuition rate, for that course. State law permits students to withdraw from no more than six courses during their entire undergraduate career at Texas public colleges or universities. With certain exceptions, all course withdrawals automatically count towards this limit. Details regarding this policy can be found in the ACC college catalog. Incompletes: Incomplete grades (I) will be given only in very rare circumstances. Generally, to receive a grade of "I", a student must have taken all examinations, be passing, and after the last date to

6 withdraw, have a personal tragedy occur which prevents course completion. An incomplete grade cannot be carried beyond the established date in the following semester. The completion date is determined by the instructor but may not be later than the final deadline for withdrawal in the subsequent semester. TSI Warning for students who are not TSI complete** Students who are not TSI complete in math are not allowed to enroll in any course with a math skill requirement. All students are required to be "continually in attendance" in order to remain enrolled in this course. If this is the only developmental class you are enrolled in, and you withdraw yourself from this course or are withdrawn by your instructor, then: a) You may be withdrawn from courses that you should not be enrolled in, such as any class with a math skill requirement. b) You will have a hold placed on your registration for the following semester. The Hold will require that you register for the next semester in person with an advisor or counselor and that you work with the Developmental Math Advisor during that semester. c) You will continue to face more serious consequences, up to being restricted to only registering for developmental courses, until you complete the required developmental math course or satisfy the TSI requirement in another way. More information can be found at ** If you are unsure whether or not this warning applies to you, see an ACC advisor immediately Importance of Completing Developmental Course Requirements The first steps to achieving any college academic goal are completing developmental course requirements and TSI requirements. The first priority for students who are required to take developmental courses must be the developmental courses. TSI rules state that students are allowed to take college credit courses, if they are fulfilling their developmental requirements. Because successful completion of dev courses is so important, ACC will intervene with any student who is not successfully completing developmental requirements. This intervention can mean a hold on records, requiring developmental lab classes, working with the Dev Math Advisor, and monitoring during the semester. Additional information about ACC's mathematics curriculum and faculty is available on the Internet at: Statement on Scholastic Dishonesty A student attending ACC assumes responsibility for conduct compatible with the mission of the college as an educational institution. Students have the responsibility to submit coursework that is the result of their own thought, research, or self-expression. Students must follow all instructions given by faculty or designated college representatives when taking examinations, placement assessments, tests, quizzes, and evaluations. Actions constituting scholastic dishonesty include, but are not limited to, plagiarism, cheating, fabrication, collusion, and falsifying documents. Penalties for scholastic dishonesty will depend upon the nature of the violation and may range from lowering a grade on one assignment to an F in the course and/or expulsion from the college. See the Student Standards of Conduct and Disciplinary Process and other policies at

7 Student Rights and Responsibilities Students at the college have the rights accorded by the U.S. Constitution to freedom of speech, peaceful assembly, petition, and association. These rights carry with them the responsibility to accord the same rights to others in the college community and not to interfere with or disrupt the educational process. Opportunity for students to examine and question pertinent data and assumptions of a given discipline, guided by the evidence of scholarly research, is appropriate in a learning environment. This concept is accompanied by an equally demanding concept of responsibility on the part of the student. As willing partners in learning, students must comply with college rules and procedures. Statement on Students with Disabilities Each ACC campus offers support services for students with documented disabilities. Students with disabilities who need classroom, academic or other accommodations must request them through the Student Accessibility Services (SAS formally known as OSD). Students are encouraged to request accommodations when they register for courses or at least three weeks before the start of the semester, otherwise the provision of accommodations may be delayed. Students who have received approval for accommodations from SAS for this course must provide the instructor with the Notice of Approved Accommodations from SAS before accommodations will be provided. Arrangements for academic accommodations can only be made after the instructor receives the Notice of Approved Accommodations from the student. Students with approved accommodations are encouraged to submit the Notice of Approved Accommodations to the instructor at the beginning of the semester because a reasonable amount of time may be needed to prepare and arrange for the accommodations. Additional information about this office is available at Concealed Handgun Policy The Austin Community College District concealed handgun policy ensures compliance with Section of the Texas Government Code (also known as the Campus Carry Law), while maintaining ACC s commitment to provide a safe environment for its students, faculty, staff, and visitors. Beginning August 1, 2017, individuals who are licensed to carry (LTC) may do so on campus premises except in locations and at activities prohibited by state or federal law, or the college s concealed handgun policy. It is the responsibility of license holders to conceal their handguns at all times. Persons who see a handgun on campus are asked to contact the ACC Police Department by dialing 222 from a campus phone or Refer to the concealed handgun policy online at austincc.edu/campuscarry Safety Statement Austin Community College is committed to providing a safe and healthy environment for study and work. You are expected to learn and comply with ACC environmental, health and safety procedures and agree to follow ACC safety policies. Additional information on these can be found at Because some health and safety circumstances are beyond our control, we ask that you become familiar with the Emergency Procedures poster and Campus Safety Plan map in each classroom. Additional information about emergency

8 procedures and how to sign up for ACC Emergency Alerts to be notified in the event of a serious emergency can be found at Please note, you are expected to conduct yourself professionally with respect and courtesy to all. Anyone who thoughtlessly or intentionally jeopardizes the health or safety of another individual will be dismissed from the day s activity, may be withdrawn from the class, and/or barred from attending future activities. Use of ACC All College communication to students will be sent solely to the student s ACCmail account, with the expectation that such communications will be read in a timely fashion. ACC will send important information and will notify you of any college related emergencies using this account. Students should only expect to receive communication from their instructor using this account. Likewise, students should use their ACCmail account when communicating with instructors and staff. Instructions for activating an ACCmail account can be found at Testing Center Policy Under certain circumstances, an instructor may have students take an examination in a testing center. Students using the Academic Testing Center must govern themselves according to the Student Guide for Use of ACC Testing Centers and should read the entire guide before going to take the exam. To request an exam, one must have: ACC Photo ID Course Abbreviation (e.g., ENGL) Course Number (e.g.,1301) Course Synonym (e.g., 10123) Course Section (e.g., 005) Instructor's Name Do NOT bring cell phones, smart watches or smart glasses to the Testing Center. Having these or your cell phone in the testing room, regardless of whether on or off, will revoke your testing privileges for the remainder of the semester. ACC Testing Center policies can be found at Student and Instructional Services ACC strives to provide exemplary support to its students and offers a broad variety of opportunities and services. Information on these services and support systems is available at: Links to many student services and other information can be found at: Learning Labs provide free tutoring services to all ACC students currently enrolled in the course to be tutored.
