Understanding natural selection requires mentally linking various key concepts and processes. Many students find it difficult to construct scientific explanations about natural selection and might display misconceptions. Our study aimed to investigate the understanding of natural selection and the existence of teleological or other misconceptions…

The authors intended to (a) identify the association between gender or grade level and teachers' homework (HW) feedback and (b) examine the relationship between teachers' HW feedback, HW-related behaviors (e.g., amount of HW completed), and academic achievement. Four hundred fifty-four students (Grades 5-12) participated in this study. The results…

This paper examines the process of high school students' planning investigations in the chemistry laboratory across two consecutive academic years in terms of their actions and their progress. The context is a set of five inquiry-based laboratory tasks in which participants (9th and 10th graders, 14-15 and 15-16 years of age) are required to plan…

Both students and parents have expectations about students' academic future. The present study analyses the influence of both sets of expectations when students are at age 15-16 on the level of education achieved by students when they are 23-24 years old. For this purpose, a structural equation model is estimated by three-stage least squares,…

The study reported here was conducted to investigate the perceptions of high school students on the use of educational games as a tool for teaching the periodic table of elements in a chemistry class in Spain. The 127 students who participated in this study came from six different classes in grade 10 (15-16 years old). The students' perceptions of…

The COVID-19 pandemic has significantly altered the organization and scheduling of high schools in Spain. Due to pandemic restrictions, most students from grades 9 to 11 come to class only on alternate days. In this situation, e-learning and distance learning have gained prominence as necessary methods of instruction. In this study 68 students…

This article reports of findings from a study among Spanish school students, with the goal of examining homophobia as perceived and expressed in three different contexts: education, the family and socially. A survey on adolescence and sexual diversity was administered to 128 tenth-grade students in their 4th year of secondary school in Castellón,…

Analytical writing serves to learn and communicate learning. Our goal was to determine the impact of students' bilingual profile, defined by self-evaluated bilingual competence, use of language(s) for mental operations and language(s) use across different contexts, on their developing analytical writing abilities. Catalan/Spanish bilinguals -- in…

The teaching and learning of mathematics cannot be understood without considering the resolution of word problems. These kinds of problems not only connect mathematical concepts with language (and therefore with reality) but also promote the learning related to other scientific areas. In primary school, problems are solved by using basic…

The objective of the present study was to examine the contribution of three intervention components (public commitment, resistance to advertising, and leisure promotion) on alcohol and protective variables in a school-based substance use prevention program. Participants included 480 Spanish students aged from 14 to 16 who received the…

In studies dealing with language learning strategies in the school context, the variables of proficiency and age are often difficult to isolate since students accumulate more hours of foreign language instruction as they move up from grade to grade. This study aimed to deal with these two variables independently by analysing learning strategy use…

Students often show difficulties in understanding rational numbers. Often, these are related to the natural number bias, that is, the tendency to apply the properties of natural numbers to rational number tasks. Although this phenomenon has received a lot of research interest over the last two decades, research on the existence of qualitatively…

The Second International Conference on Educational Data Mining (EDM2009) was held at the University of Cordoba, Spain, on July 1-3, 2009. EDM brings together researchers from computer science, education, psychology, psychometrics, and statistics to analyze large data sets to answer educational research questions. The increase in instrumented…
