Abstract High quality mathematics and science education can induce further acceleration of scientific and technological development of society. Despite the efforts to implement modern approaches to science education, reducing the level of students’ knowledge and skills is observable in some areas. The skills focused on the interpretation of data from tables and graphs and the ability to apply functions to solve problems were an important area for testing mathematical literacy in The OECD’s Programme for International Student Assessment (OECD PISA) 2012. Lack of skills in the use of different mathematical functions causes problems in mathematical modelling of real situations. Our research is currently aimed at developing inquiry skills of students in mathematics and diagnosing the level of their development. Inquiry based science education (IBSE) could bring improving conceptual understanding of mathematical knowledge and could increase the activity of students in learning. In the paper, we present our first experience with testing the level of development of selected students’ inquiry skills. We focus on the evaluation of tasks requiring working with different representations of data and understanding of linear functions. The paper presents also interactive learning activities that are part of our innovative methods based on applying inquiry approach to teaching linear and quadratic functions. The interactive learning activities for the investigation of the properties of functions are implemented in the dynamic geometric system Geogebra and in the spreadsheet MS Excel.

The results of the Program for International Student Assessment (PISA) study stated that literacy culture (the ability to read and write) the Indonesian people in 2012 was the second worst of 65 countries studied in the world. The problem in this study is the low learning activities and writing skills of fourth grade students of Cimanggung Elementary School, Cimanggung District, Sumedang Regency. This study aims to determine the increase in student learning activities, teacher teaching activities, and essay writing skills of grade IV students using Think Talk Write models. The instruments used in this study are observation sheets of student learning activities, observation sheets of teacher activities, and tests. The purpose of this study is to improve the ability to write essays and student learning activities, describe the steps and process / implementation of writing essay learning by applying TTW learning models (Think Talk Write), and describe whether there is an increase in the ability to write essays by applying TTW learning models (Think Talk Write) on fourth grade students of SDN Cimanggung, Cimanggung District, Sumedang Regency. The research method used is Classroom Action Research with a research design used referring to a model developed by Kemmis and Taggart, namely a spiral model that starts with: 1) planning; 2) acting / acting; 3) observation (observing); and 4) reflecting. The research subjects were 30 grade IV students of SDN Cimanggung, consisting of 15 women and 15 men. This research was conducted for 2 cycles.

Natural Science subjects consisting of Physics, Chemistry and Biology are given to all students starting from elementary school to equip students with logical, analytical, systematic, critical, and creative thinking skills, as well as the ability to work together. According to the Organization for Economics Cooperation and Development (OECD) in 2013, the conception of Science literacy in the PISA (Program for International Student Assessment) supports the importance of students developing a solid understanding of the concepts of pure science and science education and the benefits involved in exploration in the abstract world that exists. on the universe. This study resulted in an analysis of science learning strategies for students of the Department of Science Education that support higher order thinking skills in Science. Two (2) parts of the material will be discussed more focused, namely (a) learning materials and (b) learning strategies. With the learning syllabus that supports the High Order Thinking Skills (HOTS) questions, the opportunity to increase the value of Science education (Physics, Chemistry, Biology) is greater, one of which is the preparation of challenging questions. Challenging science questions will meet the criteria for high-level questions (PISA has question levels from level 1 to level 6). HOTS questions support the development of a solid understanding of pure Science and Science Education concepts. The data sources used in the preparation of this research are the results of the 2000, 2003, 2006, 2009, 2012, 2015 and 2018. PISA surveys and the 2013 curriculum book sourced from the Ministry of Education and Culture.

This paper deals with the implementation of the Bachelor's Degree in Electrical Engineering in Western Amazonia, as well as it presents an analysis of the academic performance of students in the Basic and Professional Core. The Federal University of Rondônia Foundation (UNIR), located in Porto Velho, Brazil, started the activities of the course in 2007 and continues to invest in the infrastructure and qualification of human resources in order to stimulate technological development in the region. Analyzing the performance data of the academics regarding the degree of difficulty established from the curricular offer, it is possible to infer some answers. In the course of the analysis, the databases emerged by taking note, such as students who only enroll and do not attend the course, among others. The disciplines diverged into two segments, Basic Core (NB) and Professional Core (NP). The data refers to the grades obtained by the students in all the disciplines studied and offered by the Academic Electrical Engineering Department (DAEE) in the period from 2007/1 to 2016/2. Along the analysis, two graphs demonstrated the evaluation. The analysis of the academic performance of students in the subjects during the NB and NP reinforces the result obtained in the Program for International Student Assessment (PISA), since Brazil has not obtained progress in science, reading, and mathematics averages. The results obtained indicate the necessity of effective measures in primary and secondary education since the deficit propagated to superior levels.

Abstract. We simultaneously resolve three paradoxes in academic self-concept research with a single unifying meta-theoretical model based on frame-of-reference effects across 68 countries, 18,292 schools, and 485,490 15-year-old students. Paradoxically, but consistent with predictions, effects on math self-concepts were negative for: • being from countries where country-average achievement was high; explaining the paradoxical cross-cultural self-concept effect; • attending schools where school-average achievement was high; demonstrating big-fish-little-pond-effects (BFLPE) that generalized over 68 countries, Organisation for Economic Co-operation and Development (OECD)/non-OECD countries, high/low achieving schools, and high/low achieving students; • year-in-school relative to age; unifying different research literatures for associated negative effects for starting school at a younger age and acceleration/skipping grades, and positive effects for starting school at an older age (“academic red shirting”) and, paradoxically, even for repeating a grade. Contextual effects matter, resulting in significant and meaningful effects on self-beliefs, not only at the student (year in school) and local school level (BFLPE), but remarkably even at the macro-contextual country-level. Finally, we juxtapose cross-cultural generalizability based on Programme for International Student Assessment (PISA) data used here with generalizability based on meta-analyses, arguing that although the two approaches are similar in many ways, the generalizability shown here is stronger in terms of support for the universality of the frame-of-reference effects.

Practical Implications

Abstract. In large-scale educational assessments such as the Third International Mathematics and Sciences Study (TIMSS) or the Program for International Student Assessment (PISA), sizeable numbers of test administrators (TAs) are needed to conduct the assessment sessions in the participating schools. TA training sessions are run and administration manuals are compiled with the aim of ensuring standardized, comparable, assessment situations in all student groups. To date, however, there has been no empirical investigation of the effectiveness of these standardizing efforts. In the present article, we probe for systematic TA effects on mathematics achievement and sample attrition in a student achievement study. Multilevel analyses for cross-classified data using Markov Chain Monte Carlo (MCMC) procedures were performed to separate the variance that can be attributed to differences between schools from the variance associated with TAs. After controlling for school effects, only a very small, nonsignificant proportion of the variance in mathematics scores and response behavior was attributable to the TAs (< 1%). We discuss practical implications of these findings for the deployment of TAs in educational assessments.

Educational Tracking

Despite their stated intention of providing equal educational opportunity for all, many democratic countries separate their students into different classes or even different schools based on their demonstrated academic ability and likely future career. This practice is often referred to as “tracking or “ability grouping.” This study aims to determine whether different types of educational tracking have different effects on students’ academic achievement. Specifically, this study investigates whether disparities in educational achievement between students of highly educated versus minimally educated parents are greater in countries that practice more explicit and complete forms of tracking. It also explores tracking’s effects on average achievement and overall achievement variance. Analysis of data from the 2009 Programme for International Student Assessment (PISA) indicates that tracking generally does increase score disparities between children from different educational backgrounds. Tracking is also associated with higher overall variance of scores. At the same time, tracking may have a slight positive effect on average achievement. However, results are not consistent across all countries, and patterns are different in different subject areas and for different types of tracking. The results of this study neither condemn nor extol tracking. Rather, they indicate that tracking plays a relatively minor role in determining the quality and equity of an education system.
