Particle Physics in High School: A Diagnose Study
2016
Abstract The science learning process improves when the contents are connected to students' lives. Particle physics has had a great impact in our society in the last years and has changed the theoretical picture about matter fundamental dynamics. Thus, we think that academic contents about matter components and interactions should be updated. With this study we aim to characterize the level of knowledge of high school students about this topic. We built a test with questions about classical atomic models, particle physics, recent discoveries, social implications and students opinions about it. Contrary to our first suspicion, students' answers show a high variability. They have new physics …
Guiding Student Thinking Through Teacher Questioning When Learning with Dynamic Representations
2021
Dynamic representations (e.g., dynamic geometry software GeoGebra for mathematics learning and PhET simulations for science learning) offer excellent opportunities for students to conduct investigations and to formulate explanations for the visualized phenomena. In order for this to be effective, students need guidance, for example, for planning their investigations and reflecting on their actions. One way to support students is by prompting them by using questions that are adapted to the students’ current situation. This chapter focuses on how pre-service teachers provide guidance for students through questioning and by both structuring and problematizing student learning. Data comes from …
Creencias sobre el aprendizaje de las ciencias de los estudiantes del máster de profesorado de enseñanza secundaria
2017
En este trabajo se muestran los resultados de un estudio empírico sobre las creencias de futuros docentes de enseñanza secundaria acerca de los procesos de aprendizaje de la ciencia, registradas mediante un cuestionario de escala likert que han cumplimentado 188 estudiantes del Máster de Profesorado de Educación Secundaria, de las especialidades de ciencia y tecnología. En primer lugar se han clasificado las diversas creencias por su relación con diferentes modelos didácticos y se ha realizadoun estudio descriptivo para conocer cuáles son las creencias más extendidas entre tales estudiantes. Posteriormente se ha desarrollado un análisis de las relaciones internas entre tales creencias y hem…
Secondary students' VARK sensory preferences in science learning: Are they reliable?
2020
Students’ sensory preferences (SP), that is, the ways or channels they prefer to receive the information, have been proposed as personal factors influencing science learning. Some studies relate improvement in learning to the adequacy of instructional resources to individual SP. A widely used instrument to determine SP is the VARK questionnaire. However, the individual SP has to be reliable to be considered useful to improve instruction. There are not enough studies on the reliability of this questionnaire. This study aimed to assess the reliability (temporal stability) of SP, as measured by the VARK instrument. Also, the reliability of the student’s subjective perception of his/her person…
Pre-service Primary Teachers' Scientific Knowledge and Attitudes towards Science Learning and Their Influence on Understanding of the Nature of Scien…
2016
The present study focused on the knowledge about the nature of science and the question of the extent to which this knowledge could be explained by employing scientific knowledge, as well as attitudes towards science learning. We obtained data from 171 Spanish pre-service primary school teachers on their knowledge about: a) science concepts, b) science process skills, c) the nature of science (that was split into science construction and validation and the role and function of scientific models), and d) their attitudes towards science learning. Quantitative and qualitative analyses provided interesting results: a) there were significant correlations between any pair of scores of conceptual …
Finnish Students’ Engagement in Science Lessons
2015
The decreasing number of students who are engaged in science learning has been recognised as a problem. The pre-conditions of engagement and actual engagement were examined using a novel research method to obtain detailed information on Finnish students’ engagement in different situations and to gain a better understanding of this phenomenon. The study’s participants consisted of 68 students (31 girls, 37 boys) from 9th grade and 67 students (46 girls, 21 boys) from 1st grade in upper secondary school. The research aimed to answer the following question: How does Finnish students’ engagement occur in exact and life science lessons? Participants received smartphones equipped with a smartphon…
New trends in science education
1996
I intend to review the main contributions from the impressive developments made in science education research during the last decade. These developments have made the construction of a coherent body of knowledge possible allowing us to expect a significant improvement in the science teaching/learning process. I shall refer, in particular, to the new trends in science education research, both in the domain of science learning and science teacher‐training.
Constructivism in Science Education: The Need for a Clear Line of Demarcation
2003
Some voices have recently begun to question the constructivist positions, which have been considered the most important contribution of the last decades in science education. It could be thought then, that the“constructivist consensus” might just be a new fashion that would once again lead us back to the immovable reception model of science learning. This questions, at the same time, the idea of an advance in the field of science education towards the construction of a coherent body of knowledge.
A Comparison between Habituation and Conscience mechanism in Self–Organizing Maps
2006
In this letter, a preliminary study of habituation in self-organizing networks is reported. The habituation model implemented allows us to obtain a faster learning process and better clustering performances. The liabituable neuron is a generalization of the typical neuron and can be used in many self-organizing network models. The habituation mechanism is implemented in a SOM and the clustering performances of the network are compared to the conscience learning mechanism that follows roughly the same principle but is less sophisticated.
Evolution of scientific conceptions and knowledge among gymnasium pupils
2014
International audience; Two major models investigate the relationship between conceptions and knowledge: the KVP model of Clement and the structural model of Balacheff. In order to prove the necessity to shift the conceptions as claimed by Giordan’s allosteric model, it is important to study the evolution and the relationship between conceptions and knowledge. This research deals with the following questions: what sort of relationship can be established between conceptions and knowledge? What factor can make these two parameters evolve? This study was carried out on 45 pupils (two classrooms). It intended to collect conceptions and knowledge before and after science learning training. Indiv…
