The Law of Inertia: How Understanding its History can Improve Physics Teaching

The law of inertia is a problem in teaching due to the impossibility of showing the proposition experimentally. As we cannot do an experiment to verify the law, we cannot know if it is correct. On the other hand, we know that the science based upon it is successful. A study in the history of mechanics has shown that there are different foundations for the law but also that the law plays the same role in the science since Newton. To avoid a statement of which we cannot be sure, the present paper proposes to understand the law through its function in the theory. In this case, we do not have to say how a free body moves, but rather that the rectilinear and uniform motion is the motion of reference in Newtonian mechanics.     

Differences in Motivation Towards Science Subjects Among Kibbutz and Urban High School Students

This paper study analyzes differences in motivation towards science subjects among kibbutz and urban high school students in Israel. Students' motivational traits in science were explored by a questionnaire whose items corresponded to four motivational patterns: achievement, curiosity, conscientiousness and sociability. The major findings of this study are that a) Kibbutz students were mostly sociability oriented in the learning of science, b) city students were mostly sociability and achievement oriented in the learning of science, c) city students were better achievers than kibbutz students in junior high school, while in senior high school the difference between them was nonsignificant, d) there was a significant increase in kibbutz students' achievement motivation in learning science when passing from junior to senior high school.     

WHO ACHIEVES LEVEL 2 QUALIFICATIONS DURING ADULTHOOD? EVIDENCE FROM THE NCDS

ABSTRACT:  This paper describes the characteristics of people who return to learning to achieve at least a level 2 qualification, drawing on the 1958 National Child Development Cohort Study. Results show that adults who gained level 2 were more likely than those who did not to have been engaged in a range of learning activities at earlier ages, including learning during childhood, staying in education during adolescence and undertaking courses leading and not leading to qualifications during adulthood. The factor that has the highest impact on progression by age 33 and by age 42 is early school attainment. This means that for individuals who do well at school there is a greater chance of achievement of qualifications during adulthood, even when this qualification is not achieved by age 23. We further find that socioeconomic constraints in adulthood may be less of a barrier to progression than is often believed. Taking together, these findings suggest that the main focus should be on paying particular attention to attitudinal barriers to learning, rather than just being concerned with removing economic and social constraints.     

Children’s education and mental health in Spain during and after the Civil War: psychiatry,psychology and “biological pedagogy” at the service of Franco’s regime

Abstract

This article analyses the child psychiatry and psychology developed during the Spanish Civil War and immediate postwar period. The aim is to demonstrate that, despite the existence of a certain degree of disciplinary continuity in relation to the pre-war period, both disciplines were placed at the service of Francoism. This meant that the association of psychology and psychiatry with pedagogy in order to educate/cure children played a key role in legitimising the child intervention policies of Franco’s regime, and this strategy was best reflected in Vallejo Nágera’s proposal regarding “biological pedagogy”. Finally, it analyses how psychiatry and psychology were used outside the school context to re-educate and control an infant population trapped between two worlds as the result of the Civil War.     

The challenges of a high-performance student athlete

To become a top athlete requires time, commitment and carefully planned training. Optimum adaptation to training requires the careful balancing of stress and recovery. The student athlete has to balance all these demands with the additional requirements of an academic programme. This can bring unique stresses and challenges. This research aims to investigate the challenges of combining high-level sport with academic demands. Nine elite student athletes (three females, six males) took part in semi-structured interviews around how the student athletes balanced their training and sporting demands with the academic demands of their course of study. The interviews were transcribed verbatim and analysed using grounded theory. The results suggested that the athletes had each developed their own distinct approach towards training management. Most of the subjects had experienced setback in their study and athletic performance due to overtraining or burnout. The findings highlight the need to empower and educate not only the athlete but also the coach on the impact of overtraining. Key findings from this study were the need for open coach–athlete communication, in-depth planning and the need for adequate recovery.     

On the difficulties to resurrect the beyond. A commentary on the article Learning beyond the body by Juan-Ignacio Pozo / Sobre las dificultades para resucitar el más allá. Un comentario sobre el artículo Aprender más allá del cuerpo de Juan-Ignacio Pozo

This commentary follows Pozo’s critique of psychological theories rooted in the ‘cognitive revolution’ prompted by the emergence of computer technologies in the mid-twentieth century. The core of his criticism is the assumption of the mind/body dualism built in these theories. Pozo makes the case for an approach striving to integrate mind and body while postulating the notion of a basic incarnate mind, which grows beyond the restrictions of the body by mastering the symbolic formal systems of our culture. I argue that this vision smooths the mind/body dualism without overcoming it. I elaborate on four areas in which Pozo’s theory coincides with assumptions characteristic of the mind/body dualism: explicitness, formal notations, animal cognition and representations.     

Validation of clay modeling as a learning tool for the periventricular structures of the human brain

Visualizing anatomical structures and functional processes in three dimensions (3D) are important skills for medical students. However, contemplating 3D structures mentally and interpreting biomedical images can be challenging. This study examines the impact of a new pedagogical approach to teaching neuroanatomy, specifically how building a 3D‐model from oil‐based modeling clay affects learners’ understanding of periventricular structures of the brain among undergraduate medical students in Colombia. Students were provided with an instructional video before building the models of the structures, and thereafter took a computer‐based quiz. They then brought their clay models to class where they answered questions about the structures via interactive response cards. Their knowledge of periventricular structures was assessed with a paper‐based quiz. Afterward, a focus group was conducted and a survey was distributed to understand students’ perceptions of the activity, as well as the impact of the intervention on their understanding of anatomical structures in 3D. Quiz scores of students that constructed the models were significantly higher than those taught the material in a more traditional manner (P < 0.05). Moreover, the modeling activity reduced time spent studying the topic and increased understanding of spatial relationships between structures in the brain. The results demonstrated a significant difference between genders in their self‐perception of their ability to contemplate and rotate structures mentally (P < 0.05). The study demonstrated that the construction of 3D clay models in combination with autonomous learning activities was a valuable and efficient learning tool in the anatomy course, and that additional models could be designed to promote deeper learning of other neuroanatomy topics.

The Collective that Didn't Quite Collect: Reflections on the IALS

The concept and methodology of IALS obviously represent progress for literacy research. Nevertheless, this survey presents serious limitations. It prioritises the handling of data-based information as opposed to experiential and contextualized information, ranking at a higher position those who handle the first kind of information. The survey ignores how people solve problems in their life context. The competence of people cannot be understood merely through outside observation and a questionnaire situation. In the case of Poland, the interpretation of data manifests an ethnocentric Western attitude, tending to reduce cultural differences to a cultural deficit. Two IALS-inspired surveys conducted in Spain and Portugal mixed quantitative and qualitative methods in order to take into account the social relations in their cultural context. This article questions the role of research, which cannot be limited to the objectivation of reality, but should help to transform and improve it. The alternative model proposed is named "investigation action."     

The role of domain knowledge in cognitive modeling of information search

Computational cognitive models developed so far do not incorporate individual differences in domain knowledge in predicting user clicks on search result pages. We address this problem using a cognitive model of information search which enables us to use two semantic spaces having a low (non-expert semantic space) and a high (expert semantic space) amount of medical and health related information to represent respectively low and high knowledge of users in this domain. We also investigated two different processes along which one can gain a larger amount of knowledge in a domain: an evolutionary and a common core process. Simulations of model click behavior on difficult information search tasks and subsequent matching with actual behavioral data from users (divided into low and high domain knowledge groups based on a domain knowledge test) were conducted. Results showed that the efficacy of modeling for high domain knowledge participants (in terms of the number of matches between the model predictions and the actual user clicks on search result pages) was higher with the expert semantic space compared to the non-expert semantic space while for low domain knowledge participants it was the other way around. When the process of knowledge acquisition was taken into account, the effect of using a semantic space based on high domain knowledge was significant only for high domain knowledge participants, irrespective of the knowledge acquisition process. The implications of these outcomes for support tools that can be built based on these models are discussed.
