Mathematics Anxiety: Its Influence on Mathematics Performance Among First Year Bsmt Students of St. Mtcc, Tigbauan

...CHAPTER 2 REVIEW OF RELATED LITERATURE AND STUDIES Mathematics Anxiety For as long as there are people on earth, mathematics is here to stay and mathematics anxiety is something people must learn to deal with (Pinno, 1996). Tobias describes math anxiety as a feeling of sudden death as “an obsession with the idea that everyone knows that i don’t understand; I’d better not draw attention to myself by asking serious math avoidance and math phobia (Tobias, 1978). Math anxiety usually arises from a lack of confidence when working on mathematical situations. Math anxiety is defined in a variety of ways. Richardson and Suinn(1972)suggests that mathematics anxiety involves feelings of tension and anxiety that interfere with the manipulation of numbers and the solving of mathematical problems in a wide variety of ordinary life and academic equations. Hodges (1983) differentiates between math anxiety and mathopobia. She believes that failure in mathematics leads to frustration, and the students then develop “math anxiety.” the result is a not too-common illness: mathopobia. A succinct description of math anxiety, which will be used interchangeably in this research, is that it is both emotional and cognitive dread of mathematics (Hodges, 1983 Reyes 1980; Seguin 1984; Tobias, 1976, 1978). Causes of Math Anxiety Miller (1997) points out that math anxiety usually comes from negative experiences in working with teachers, tutors, classmates, parents or siblings. At other times...

Development and Validation of Instructional Material Using Mathematics Software

...CHAPTER I INTRODUCTION This study presents the background of the study, the statement of the problem, the significance of the study, and the scope and delimitation of the study. Background of the Study In a globalized economy with a high degree of competition among countries, the success of a nation depends on the educational level of its workforce. Governments should work to ensure that all citizens receive the technological training and experience necessary to participate in the global economy. Education reform is essential to provide learners with what are commonly called 21st century skills — those competencies and values needed to become responsible citizens in a learning society and sustain employability throughout life in a knowledge economy. Thus, the researcher decided to formulate this research to provide our educational system one of the devices that will make a difference in the manner of teaching. In classrooms, technology can be a powerful catalyst for pedagogical change, as students use technology to take a more active role in personalizing their own education, and teachers take on new roles as facilitators of knowledge rather than knowledge transmitters. Our educational system as well as the curriculum has gone through many different changes and development. As defined, development is the systematic use of scientific and technical knowledge to meet specific objectives or requirements. It is the process of adding improvements to a theoretical or practical...

Importance Of Mathematics Comprehension

...connections between language, symbols, pictures and real-life situations. This statement comes as a support for the idea that “language effects the ability to solve mathematical problems”. Further, Euclid (1956; 46) indicates that "Just as procedural mathematics courses tend to focus on plug and chug with an emphasis on symbolic manipulation, so conceptual mathematics courses focus on proof and argument with an emphasis on correct, clear, and concise expression of ideas. This is a difficult but crucial leap for students to make in transitioning from rudimentary to advanced mathematical thinking. At this stage, the classical tritium of grammar, logic, and rhetoric becomes an essential ally.” It is shown in this statement how important language accuracy and constant development of language...

Starderlized Tests

...Standardized Tests Keisha Rucker English 102 11/11/2012 Rachel Hawley Standardized Tests What is Standardized Tests? Standardized Tests is a test that is administered and scored in a consistent or standard manner. Some different types of standardized tests are SAT, ACT, and ISAT. These different tests are biased in the public school system across the United States. Standardized test take up a lot of student’s energy, adds a lot of stress, and takes away from their creativity and social life. Standardized tests are just one measure of performance in a Student’s portfolio, according to education commissioner Peter McWalters (Jordan, 2005). WASHINGTON, D.C., Standardized tests are "like a lock on the mind, a guard at the factory gate," the executive director of the National Education Association said today, noting that "the only real beneficiaries, aside from the test marketers themselves, are insecure school managers striving for comfort in their relations with school boards, legislators, and governors”( Standardized tests, 1976). Critics have demonstrated that many standardized test are biased because their questions tap a set of knowledge and skills more likely to be possessed by children from a privileged background (Kohn, 2000). Most tests are written by people who don’t have any experience teaching students. Students from different cultures may lace higher importance on different skills. They may be stronger or weaker in areas tested compared to other students of...

Malaysian Students Are Poor Problem Solvers, Survey Says

...Published: Wednesday April 2, 2014 MYT 12:20:00 PM Updated: Wednesday April 2, 2014 MYT 1:32:48 PM Malaysian students are poor problem solvers, survey says BY PATRICK LEE Email Facebook 1K PETALING JAYA: When it comes to problem-solving, Malaysian 15year-olds are among of the world’s poorest, a survey by Programme for International Student Assessment (PISA) has determined. The 2012 survey conducted by the Organisation for Economic Cooperation and Development (OECD) found that more than one in five Malaysian students could not even reach basic levels of problem solving. Malaysia came in at 39th with a mean score of 422 points among the 44 countries surveyed. In comparison, Singapore topped the list of countries with 562 points. Malaysia’s score also put it below the OECD average of 500 points. The survey divided problem solving proficiency into six levels, with Level 6 being the highest and Level 1 being the lowest, though it was added that there was a level below Level 1. “... and in Uruguay, the United Arab Emirates, Montenegro, Malaysia, Brazil and Israel, more than one in five students do not reach this level (Level 1),” the report said. The PISA 2012 report said students proficient at Level 1 can only explore problems given to them in a limited manner. “In general, students at Level 1 can solve straightforward problems provided there is only a simple condition to be satisfied and there are only one or two steps to be performed to reach that goal.” According to the...

The Measurement of Education Through Testing

...precise and accurate measuring tool to this cognitive ability. The closest measuring tool we have in our modern day era is the use of standardized exams and grade point averaging to try to figure out just how educated and learned the students in today’s world are. Measuring education in this modern school system is mainly based on end of the year final exams and standardized measuring numbers such as grade point averages and SAT scores. Although these exams and numbers do give a roughly good measurement of a certain student’s education level, it doesn’t necessarily mean that said student is as smart as those scores, which is the true wanted result to measure of these tests. These tests do require a certain level of cognitive ability, but there are other situations that can be factored in to take away the validity of these tests to a certain degree. For example, if a student studies solely for the SAT since the beginning of their high school career, they will most likely post a score that puts them well into the high upper percentile of the nation. However, that doesn’t necessarily mean he/she is the same percentile in cognitive ability in the nation. Not that there is any wrong doing in studying for the SAT for that lengthy period of time, but it shouldn’t such a solid truth type of test to measure how smart someone really is. Of course, in some cases the SAT can be an accurate measurement of a student’s cognitive ability because a student may actually be smart in all those areas...

The Mathematics Educator 2005, Vol. 8. N0.2. 53-70 Working with Logarithms: Students' Misconceptions and Errors Chua Boon Liang and Eric Wood National Institute of Education, Nanyang Technological University Abstract: This study examines secondary school students' understandings and misconceptions when working with logarithms using a specially designed test instrument administered to 81 students in two Singapore schools. Questions were classified by cognitive level. The data were analysed to uncover the kinds of errors made and their possible causes. Students appear capable of doing routine calculations but less capable when answering questions which require higher levels of cognitive thinking. In addition, many errors are not due to lack of knowledge but appear to be based on over-generalisation of algebraic rules. Suggestions for practice based on these findings are provided. Introduction Anecdotal evidence from teachers and colleagues over the years has consistently confirmed that teaching logarithms in secondary school...

...Chapter I Introduction Background of the Study This study was conducted by the Fourth Year student of Aklan State University taking up Bachelor of Elementary Education to determine that one of the factors that affect pupil’s performance is the pupils Study Skills or their Poor Study Habits. Good education in Mathematics is important because of its usefulness in different careers. Since mathematics deals with accuracy and precise thinking, pupils must be able to understand the basics. Student’s performance toward mathematics can contribute to better results in Mathematics; hence poor performance such as poor study habits, and poor study skills resulted to attribute such difficulty to this subject. Difficulty in this subject somehow depends in how individual study skills were use. Difficulty also exists because they easily forget their previous lesson that shows they lack the will to study. It is important to learn how to think about and understand math problems thoroughly. Math study skills can help you learn the mathematical concepts, skills, and principles that is important to other parts of your life.  Additionally, math study skills are tools that can serve you well in college, work, and other learning situations. The SQ3R method has been proven to sharpen study skills. SQ3R stands for Survey, Question, Read, Recite, and Review. SQ3R is an abbreviation to help you remember the steps and to make references to it simpler. The symbols stand for the steps followed in using...

...CLAT 2013- The Countdown begins The countdown for the Common Law Admission test (CLAT 2013) has begun. With less than 50 days left for CLAT, which is the stepping stone for the National Law Universities across the country, the anxiety amongst the students is rising. Gyan Central caught up with Saiyed Anzar Abbas, founder of CLATapult, one of the premier coaching institutes for CLAT, to ask him about his views and tips for students appearing in CLAT 2013. GC- Congratulations Anzar for the immense success of your brainchild-CLATpult. Anzar- Thank you very much. This success is mainly attributed to the dedication and support of all my friends and well wishers. The true success of CLATapult shall be reflected in the CLAT 2013 results in which I am confident that the students of CLATapult would pass with flying colors. GC- The first question which comes to the mind of any student who is contemplating to start preparation for CLAT 2013 is whether 50 days is an adequate time period for preparation for CLAT. Anzar- CLAT, unlike other exams like the IIT-JEE or AIEEE, is not an examination which requires dedicated study for a period of years together. CLAT requires dedicated study for a shorter duration as compared to other examinations. Though 50 days is a very short time period, it still is not inadequate for the preparation for CLAT. 50 days of immense hard work, dedication and sincerity is enough to guarantee a student to crack CLAT 2013.
