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…

We studied the emotions experienced by students during the last two years of compulsory secondary education (15 and 16 years old) when learning physics and chemistry. The objective of this piece of research was to establish different relationship between emotions felt by students and variables like the didactic methodology or the kind of science…

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 role played on shallow and deep levels of comprehension by text changes aimed at improving relationships within text ideas or producing better links with the reader's knowledge were studied with 67 Spanish 10th graders. Both textual changes contributed separately to recall, but problem solving increased only when the two were presented…
