Examination of the 8th grade students' TIMSS mathematics success in terms of different variables1

The aim of this study is to determine how the TIMSS mathematics success of the 8th grade students differentiates according to the school type, gender, mathematics report mark, parents' education level, cognitive domains and cognitive domains by gender. Relational survey method was used in the study. Six-hundred fifty two 8th grade students studying in the same city in Turkey participated in this study. In this study, a 45 question test that was made up by choosing TIMSS 2011 mathematics questionnaire was used as a data collection tool. Quantitative data analysis methods were used in the data analysis, frequency, percentage, average, standard deviation, independent sample test, one-way analysis of variance and post-hoc tests were applied to data by using SPSS packaged software. At the end of the study, it was determined that the school type, mathematics school mark, parents' education level and cognitive domains influenced the students' TIMSS mathematics success but their gender was a neutral element. Moreover, it was seen that schools which are really successful in national exams are more successful in TIMSS exam; students whose mathematics school marks are 5 and whose parents graduated from university are more successful in TIMSS exams than others.     

Development of a mathematical ability test: a validity and reliability study

The identification of talented students accurately at an early age and the adaptation of the education provided to the students depending on their abilities are of great importance for the future of the countries. In this regard, this study aims to develop a mathematical ability test for the identification of the mathematical abilities of students and the determination of the relationships between the structure of abilities and these structures. Furthermore, this study adopts test development processes. A structure consisting of the factors of quantitative ability, causal ability, inductive/deductive reasoning ability, qualitative ability and spatial ability has been obtained following this study. The fit indices of the finalized version of the mathematical ability test of 24 items indicate the suitability of the test.

Teaching metrology and quality in chemistry based on methods of mathematical statistics and e-learning

Chemistry students do not usually have the necessary background in mathematical statistics to study metrology and quality principles in chemistry. Even when the students have studied mathematical statistics, it is helpful to refresh their statistical knowledge, focusing on specific applications to metrology and quality in chemistry. Therefore, when planning a course for teaching metrology and quality it is important to achieve a harmonized interaction of metrological and quality issues with the supporting statistical issues. Additional possibilities for learning the relevant subjects originate from the Internet (e-learning). Such a lecture course developed and delivered during the five years since 2003 at the Hebrew University of Jerusalem is discussed in the paper.

Rate of Change: AP Calculus Students' Understandings and Misconceptions After Completing Different Curricular Paths

This study examined Advanced Placement Calculus students' mathematical understanding of rate of change, after studying four years of college preparatory (integrated or single‐subject) mathematics. Students completed the Precalculus Concept Assessment (PCA) and two open‐ended tasks with questions about rates of change. After adjusting for prior achievement with the Iowa Algebra Aptitude Test, students from these two paths performed comparably (F = 3.54, p = .063) on the PCA. Student errors on the three instruments revealed a lack of understanding of the interpretation or meaning of rate of change regardless of the curricular path. Students successfully calculated the rate of change of linear functions; however, when the function was not linear, students struggled to calculate it, model it on a graph, or interpret it in a real‐world context.
