This study diagnoses and explores year eight students' misconceptions and mistakes in algebra. An in-depth exploration of students' misconceptions were carried out by conducting interviews based on the students' work as outlined in a cognitive map. Based on the cognitive maps, it can be seen that the students emphasize procedural knowledge rather…

The aim of this study is to determine the students' misconceptions about the digestive system. In this quantitative research, the study group comprised totally 259 sixth-, seventh-, and eighth-grade students. The data were collected through a three-tier diagnostic test and analyzed in terms of scientific knowledge, the lucky guess, lack of…

The aim of this study was to investigate the levels of secondary school students' knowledge about three Global Environmental Problems: Global Warming, Acid Rain, and Ozone Layer Depletion. 638 7th grade (N=316) and 8th grade (N=322) students enrolled in five different secondary schools participated in this study. The survey method was used to…

The study aimed to develop a Likert-type measurement tool (Digital Literacy Scale, DLS) to determine the digital literacy levels of secondary school students. The validity and reliability of the developed measurement tool were verified using the Rasch model. The Rasch Model can estimate missing data and allow for small study groups (Rasch, Rasch,…

Measuring teachers' skills and competencies is necessary to ensure teacher quality and contribute to education quality. Research has shown teachers competencies and skills influence students' performances. Previous studies explored teachers' knowledge through testing. Teachers' knowledge of the topic of area-perimeter and teaching strategies has…

Since the release of "A Framework for K-12 Science Education" in 2012, there has been a significant shift toward the use of science and engineering practices that mirror the way scientists do their work (NRC 2012). The "Framework" states, "A focus on practices (in the plural) avoids the mistaken impression that there is…

The United States is currently experiencing its most severe measles outbreak in decades, driven in part by parents' belief that vaccines cause autism. That harmful misinformation is contrary to scientific evidence (DeStefano et al. 2013). The CEO of the American Association for the Advancement of Science, the world's largest multidisciplinary…

The purpose of this research is the determination of the effect of the activities of the planetarium on students' views, three-dimensional thinking skills and academic achievement. Mixed method was used in the research. The embedded pattern is preferred because qualitative data are supported by quantitative data that was used a single group…

The animal migration is one of the natural processes and is important not only for animals but also for people. Although this process is inseparable part of the nature, its incorporation into curriculum is on low level, not only in Czech Republic, but also in many other countries. The aim of the research was to identify lower secondary school…

This study investigated if and to what extent grade 8 and 9 students in Taiwan attributed materialistic properties to sound concepts, and whether they hold scientific views in parallel with materialistic views. Taiwanese middle school students are a special population since their scores in international academic comparison tests such as TIMSS and…

Students commonly find the field of physics difficult. Therefore, they generally have learning problems. One of the subjects with which they have difficulties is optics within a physics discipline. This study aims to determine students' conceptual understanding levels at different education levels relating to lenses in geometric optics. A…

This work investigates the formation of particular student profiles based on of their ideas relating to basic characteristics of the atom. Participants were secondary students of 8th, 10th and 12th grades from Northern Greece (n = 421), with specific cohort characteristics e.g. age, grade and class curriculum, and individual differences, e.g.…

Students' misconceptions concerning colour phenomena and the apparent complexity of the underlying concepts--due to the different domains of knowledge involved--make its teaching very difficult. We have developed and tested a teaching device, the addition table of colours (ATC), that encompasses additive and subtractive mixtures in a single…

It is important to structure children's knowledge and arouse their interest in subjects like astronomy and space. Although we now talk of travelling to the moon, space tourism etc., knowledge about astronomy and space is limited and perceptions of these subjects do not reflect scientific reality. Primary level students often have misconceptions…

Modern biology has become increasingly molecular in nature, requiring students to understand basic chemical concepts. Studies show, however, that many students fail to grasp ideas about atom rearrangement and conservation during chemical reactions or the application of these ideas to biological systems. To help provide students with a better…
