In the physics class: university physics students’ enactment of class and gender in the context of laboratory work

This article explores how the doing of social class and gender can intersect with the learning of science, through case studies of two male, working-class university students’ constitutions of identities as physics students. In doing so, I challenge the taken-for-granted notion that male physics students have an unproblematic relation to their chosen discipline, and nuance the picture of how working-class students relate to higher education by the explicit focus on one disciplinary culture. Working from the perspective of situated learning theory, the interviews with the two male students were analysed for how they negotiated the practice of the physics student laboratory and their own classed and gendered participation in this practice. By drawing on the heterogeneity of the practice of physics the two students were able to use the practical and technological aspects of physics as a gateway into the discipline. However, this is not to say that their participation in physics was completely frictionless. The students were both engaged in a continuous negotiation of how skills they had learned to value in the background may or may not be compatible with the ones they perceived to be valued in the university physicist community.     

Scaffolding writing using feedback in students’ graphic organizers – novice writers’ relevance of ideas and cognitive loads

This paper aims to find out two outcomes of feedback in the novice writers’ graphic organizers, which are the novice writers’ ability to align their ideas to their writing goal, and their perceived germane, metacognitive, extraneous and intrinsic cognitive loads when generating and revising ideas based on the feedback. Data was gathered from the students’ graphic organizers, mental difficulty questionnaires and focus group discussion. The findings show that the students’ relevance of ideas improved with feedback in their organizers, except for one sub‐process. In addition, the students’ metacognitive load seems to affect the amount of ideas generated. These findings have implications for media selection mix and social collaborative environments.

Rückmeldung über graphische Organizer von Studenten unterstützt das Schreiben – Relevanz von Anfänger Ideen und Erinnerungsnotizen

Mit diesem Beitrag soll versucht werden, die Ergebnisse zweier Rückmeldungen über die graphischen Organizer von Anfängern zu finden: die Fähigkeit des Anfängers seine Gedanken dem Schreibziel anzupassen und seine erwartete Relevanz metakognitiv, sachfremde und intrinsisch kognitive Beiträge beim Erzeugen und Überprüfen von Ideen, die auf dem Feedback beruhen, zu nutzen. Die Daten wurden auf den graphischen Organizern der Studenten gesammelt, ebenso schwierig zu bearbeitende Fragebögen und Gruppendiskussionen. Es zeigte sich, dass die Relevanz der Ideen mit dem Feedback auf den Organizern der Studenten wuchsen, außer für einen Sub‐Prozess. Zusätzlich scheint der metakognitve Beitrag der Studenten die Menge der erzeugten Ideen zu beeinflussen.

Un appui à l’écriture reposant sur l’usage de la rétroalimentation dans les organisateurs graphiques des étudiants ‐ sur la pertinence des idées des novices de l’écrit et sur les charges cognitives

Le but du présent article est de trouver deux résultats de la rétroaction dans les organisateurs graphiques des apprentis écrivains nommément: la capacité des novices de l’écrit pour aligner leurs idées sur leurs objectifs d’écriture et les charges métacognitives appropriées, étranges et intrinsèques telles qu’ils les perçoivent lorsqu’ils révisent ou produisent des idées fondées sur la rétroaction. On a recueilli des données provenant des organisateurs graphiques des étudiants, des questionnaires sur la difficulté intellectuelle et les discussions de groupes ciblées. Les résultats obtenus montrent que que la pertinence des idées des étudiants s’améliorait avec la rétroaction dans leurs organisateurs sauf pour un sous‐processus. En outre la charge métacognitive des étudiants semble affecter la quantité d’idées produites.

Un apoyo a la escritura basado en el uso de la retroalimentación en los organizadores gráficos de los estudiantes, en la pertinencia de las ideas de los novatos de la escritura y en las cargas cognitivas

La finalidad de este artículo es de encontrar dos resultados en la retroalimentación de los organizadores gráficos de los novatos de la escritura que serían: _la capacidad de los dichos novatos de sintonizar sus ideas con sus objetivos de escritura y_ las cargas metacognitivas ajenas y intrinsecas tal como las perciben cuando producen o revisan ideas basadas en la retroalimentación. Datos fueron recogidos de los organizadores gráficos de los estudiantes, de los cuestionarios de agilidad intelectual y de los debates de grupos enfocados. Los resultados muestran que la pertinencia de las ideas de los estudiantes mejoró con la retroalimentación en sus organizadores si no fuera por un solo subproceso. Además a lo que parece, la carga metacognitiva de los estudiantes afecta la cantidad de ideas producidas.     

Students’ assessment of interactive distance experimentation in nuclear reactor physics laboratory education

Laboratory experiments develop students’ skills in dealing with laboratory instruments and physical processes with the objective of reinforcing the understanding of the investigated subject. In nuclear engineering, where research reactors play a vital role in the practical education of students, the high cost and long construction time of research reactors limit their accessibility to few educational programmes around the world. The concept of the Internet Reactor Laboratory (IRL) was introduced earlier as a new approach that utilises distance education in nuclear reactor physics laboratory education. This paper presents an initial assessment of the implementation of the IRL between the PULSTAR research reactor at North Carolina State University in the USA and the Department of Nuclear Engineering at Jordan University of Science and Technology (JUST) in Jordan. The IRL was implemented in teaching the Nuclear Reactor laboratory course for two semesters. Feedback from surveyed students verifies that the outcomes attained from using IRL in experimentation are comparable to that attainable from other on-campus laboratories performed by the students.     

University students’ grasp of inflection points

This paper describes university students’ grasp of inflection points. The participants were asked what inflection points are, to mark inflection points on graphs, to judge the validity of related statements, and to find inflection points by investigating (1) a function, (2) the derivative, and (3) the graph of the derivative. We found four erroneous images of inflection points: (1) f ′ (x)?=?0 as a necessary condition, (2) f ′ (x)?≠?0 as a necessary condition, (3) f ″ (x)?=?0 as a sufficient condition, and (4) the location of “a peak point, where the graph bends” as an inflection point. We use the lenses of Fischbein, Tall, and Vinner and Duval’s frameworks to analyze students’ errors that were rooted in mathematical and in real-life contexts.     

The analysis and reconciliation of students’ rebuttals in argumentation activities

The present study investigated the guidance provided by science teachers to resolve conflicts during socioscientific issue-based argumentation activities. A graphical representation (GR) was developed as a tool to code and analyze the dialogue interaction process. Through the GR and qualitative analysis, we identified three types of dialogue reconciling strategies. The first one consists of teacher management, in which the teacher temporarily maintains the right to speak when students get mired in an emotional rebuttal situation. The second strategy involves the use of qualifiers to identify the strengths and weaknesses of an opposing argument. The third strategy consists of providing students with guidance to keep both parties (i.e. the students taking, respectively, the affirmative and negative positions) on the same discussion topic and can be used to assist teachers with forming broad questions that prompt students to conduct deeper discussions. These reconciling strategies were beneficial in that they helped students to argue in a more reflective way.     

Unpacking students’ epistemic cognition in a physics problem-solving environment

It is a widely held view that students’ epistemic beliefs influence the way they think and learn in a given context, however, in the science learning context, the relationship between sophisticated epistemic beliefs and success in scientific practice is sometimes ambiguous. Taking this inconsistency as a point of departure, we examined the relationship between students’ scientific epistemic beliefs (SEB), their epistemic practices, and their epistemic cognition in a computer simulation in classical mechanics. Tenth grade students’ manipulations of the simulation, spoken comments, and behavior were screen and video-recorded and subsequently transcribed and coded. In addition, a stimulated recall interview was undertaken to access students’ thinking and reflections on their practice, in order to understand their practice and make inferences about their process of epistemic cognition. The paper reports on the detailed analysis of the data sets for three students of widely different SEB and performance levels. Comparing the SEB, problem solutions and epistemic practices of the three students has enabled us to examine the interplay between SEB, problem-solving strategies (PS), conceptual understanding (CU), and metacognitive reflection (MCR), to see how these operate together to facilitate problem solutions. From the analysis, we can better understand how different students’ epistemic cognition is adaptive to the context. The findings have implications for teaching science and further research into epistemic cognition.     

University students’ and teachers’ conceptions of teaching and learning in the biosciences

In this study we compare university teachers’ and first-year students’ conceptions of teaching and learning at the Faculty of Environmental and Biological Sciences. The conceptions were analysed using data from open-ended questionnaires. The results showed that at the beginning of studies the gap between teachers’ and students’ conceptions of teaching and learning is substantial. This finding has important implications for the educational process. In order to enhance successful studying from the beginning of students’ university careers, it is important for teachers to become aware of the differences between students’ and teachers’ conceptions of learning.     

The learners’ experience of variation: following students’ threads of learning physics in computer simulation sessions

This article attempts to describe students’ process of learning physics using the notion of experiencing variation as the basic mechanism for learning, and thus explores what variation, with respect to a particular object of learning, that students experience in their process of constituting understanding. Theoretically, the analysis relies on analytic tools from the phenomenographic research tradition, and the recent group of studies colloquially known as the variation theory of learning, having the notion of experiencing variation as a key for learning at its core. Empirically, the study relies on video and audio recordings of seven pairs of students interacting in a computer-simulation learning environment featuring Bohr’s model of the atom. The data was analysed on a micro-level for the emergence of student-recognised variation, depicted in terms of ‘threads of learning’. This was done by linking variation around aspects of the object of learning present in the situation, and attended to by the students, to new ways of seeing—characterised as an expanding anatomy of awareness, and hence as learning. The students’ threads of learning are characterised in terms of two stages of learning progress: (1) discerning variation, and (2) constituting meaning from this experience of variation (experienced as holistically relevant in the students’ conceptual domain of physics and the Bohr model). Two groups of threads of learning were identified: one where the variation experienced by students was within an aspect of the object of learning, and one where variation was across several aspects.     

Interaction of the originality of peers’ ideas and students’ openness to experience in predicting creativity in online collaborative groups

There has been growing interest in the possibility that peers’ ideas can stimulate students’ creativity in group contexts. However, empirical research on this issue is limited. This study tested the hypothesis that peers’ ideas and students’ openness to experience would predict student creativity and attention to peers’ ideas. Undergraduate students (n = 60) completed creative tasks in an online collaborative group in which the ideas of “peers” were pre-programmed. Mixed ANOVAs showed support for the hypothesis. Specifically, students with higher (but not lower) openness, when exposed to a high (but not low) rate of peers’ original ideas, paid greater attention to those ideas and were more creative. The implication for education is that teachers should encourage students to share more of their original ideas and to pay more attention to peers’ ideas in online collaborative groups.     

Engineering students’ experiences from physics group work in learning labs

The development and validation of a test of biology‐related attitudes (TOBRA) is described. This instrument was developed for science students in grades 10‐12 in Indonesia; however, the procedures for validation of the instrument will be of general interest to science educators. These procedures included the use of latent partition analysis to examine the conceptual structure of TOBRA.     

University students’ conceptions of learning across multiple domains

Research on students’ conceptions of learning is a growing and complex area of interest in the field of psychology of education. Even though much of the investigation addressed to explore conceptions of learning at the university level, still less research has considered how naïve (i.e. ‘learning as reduction of deficit knowledge through individual effort’) and sophisticated (i.e. ‘learning as opportunity and self-efficacy’) conceptions of learning are related to personal and contextual factors. This research investigated how gender, academic area, and level of study influence university students’ conceptions of learning. Three hundred forty-six university students participated in the study. They were either from humanities (240) or technical-scientific (106) areas of study and they were attending either a Bachelor (140) or Master’s degree (206) course. Conceptions of learning were explored using a self-report instrument (Learning Conceptions Questionnaire; LCQ). A MANOVA revealed that females show conceptions of learning more related to social and motivational aspects of learning with a greater personal involvement, compared with males. No typical pattern of conceptions of learning was found for humanities students or for technical-scientific students. Increasing with the level of study, students showed both naïve and sophisticated conceptions of learning increased, since both ‘learning as reduction of deficit knowledge through individual effort’ and ‘learning as opportunities and self-efficacy’ were more likely. Implications of these results and future lines of research will be discussed.     

Agreed discoveries: students’ negotiations in a virtual laboratory experiment

This paper presents an analysis of the scientific reasoning of a dyad of secondary school students about the phenomenon of dissolution of gases in water as they work on this in a simulated laboratory experiment. A web-based virtual laboratory was developed to provide learners with the opportunity to examine the influence of physical factors on gas solubility in water. An evaluation process involving 180 students revealed that the concepts connected to the dissolution of gas in water caused problems for the students even after having experimented with the virtual laboratory. To investigate the nature of learners’ reasoning about the visualised events, 13 video-recorded groups of learners were analysed. This study follows the reasoning of one group that displayed a possibly productive way of solving the problem. The results address the students’ general difficulty of discovering something that they are conceptually unprepared for within the virtual laboratory. The analysis shows how the students eventually found a way out of their dilemma by making an analogy with other dissolving processes. In effect, the analysis elucidates some of the analytical work that had to be done by the participants when collaboratively negotiating a shared meaning of a scientific concept in concord with a given task and set of instructional materials. Implications for design might be to provide the learning material with explicit hints that enable students to connect to specific phenomena related to the one investigated concept. The findings show the usefulness of video analytic research, informed by CA and ethnomethodology. This analytical framework can support design processes and provide useful information, which might identify hurdles to learning a scientific concept by simulated events and pathways to overcome these hurdles.     

Mapping students’ ideas to understand learning in a collaborative programming environment

Recent studies in learning programming have largely focused on high school and college students; less is known about how young children learn to program. From video data of 20 students using a graphical programming interface, we identified ideas that were shared and evolved through an elementary school classroom. In mapping these ideas and their resulting changes in programs and outputs, we were able to identify the contextual features which contributed to how ideas moved through the classroom as students learned. We suggest this process of idea mapping in visual programming environments as a viable method for understanding collaborative, constructivist learning as well as a context under which experiences can be developed to improve student learning.     

The influence of extracurricular activities on middle school students’ science learning in China

ABSTRACT

Informal science learning has been found to have effects on students’ science learning. Through the use of secondary data from a national assessment of 7410 middle school students in China, this study explores the relationship among five types of extracurricular science activities, learning interests, academic self-concept, and science achievement. Structural equation modelling was used to investigate the influence of students’ self-chosen and school-organised extracurricular activities on science achievement through mediating interests and the academic self-concept. Chi-square tests were used to determine whether there was an opportunity gap in the student’s engagement in extracurricular activities. The students’ volunteer and school-organised participation in extracurricular science activities had a positive and indirect influence on their science achievement through the mediating variables of their learning interests and academic self-concept. However, there were opportunity gaps between different groups of students in terms of school location, family background, and especially the mother’s education level. Students from urban areas with better-educated mothers or higher socioeconomic status are more likely to access diverse science-related extracurricular activities.     

Episodic memories and the longitudinal impact of high school physics on female students’ physics identity

Students enter physics classes with negative attitudes towards physics compared to the other sciences. Female students are more likely to opt out of a second higher-level physics course. Thus, the broad goal of this work is to better understand how to have the most lasting positive impact on female students’ attitudes and motivations towards learning physics after a single physics course in high school. Through longitudinal case studies of six female students using the frameworks of episodic memory and physics identity, we explore the most impactful features of students’ high school physics experiences. The data is drawn from three years of student interviews and one initial student survey. Our results indicate that the students could remember in detail and with longevity their experiences with physics causing high arousal and negative initial valence, such as teachers presenting physics knowledge in a counter-intuitive way. The students can remember the context but not the details of their experiences with physics causing low arousal and non-neutral valence, such as their teacher sharing a story about physics. Experiences that were eventually tied to positive valence had positive impacts on female students’ physics identity maintenance, such as problem solving activities where no one was left behind.     

University students’ use of motivational regulation during one semester

This study examined the interplay between university students' trajectories of motivational regulation and autonomous motivation across one semester, exploring both between and within person components. Participants (N = 193) from one large class reported motivation in two-week intervals over the course of one semester. Bivariate latent curve models with structured residuals revealed rates of change in motivational regulation and autonomous motivation were not linear, declining across the first ten weeks of the semester then bouncing back in the final month. Between-person effects of individual change demonstrated mirroring relationships of latent intercepts and slopes across the semester. Within-person findings revealed that autonomous motivation was a negative predictor of future motivation regulation. Students' grade point average only predicted students’ beginning level of motivational regulation. It appears that students with higher states of autonomous motivation view motivation regulation as unnecessary or even a potential threat to their learning pleasure and satisfaction.     

High school students’ approaches to learning physics with relationship to epistemic views on physics and conceptions of learning physics

Background and purpose : Knowing how students learn physics is a central goal of physics education. The major purpose of this study is to examine the strength of the predictive power of students’ epistemic views and conceptions of learning in terms of their approaches to learning in physics. Sample, design and method : A total of 279 Taiwanese high school students ranging from 15 to 18?years old participated in this study. Three questionnaires for assessing high school students’ epistemic views on physics, conceptions of learning physics and approaches to learning physics were developed. Step-wise regression was performed to examine the predictive power of epistemic views on physics and conceptions of learning physics in terms of their approaches to learning physics. Results and conclusion: The results indicated that, in general, compared to epistemic views on physics, conceptions of learning physics are more powerful in predicting students’ approaches to learning physics in light of the regression models. That is, students’ beliefs about learning, compared with their beliefs about knowledge, may be more associated with their learning approaches. Moreover, this study revealed that the higher-level conceptions of learning physics such as ‘Seeing in a new way’ were more likely to be positively correlated with the deep approaches to learning physics, whereas the lower-level conceptions such as ‘Testing’ were more likely to positively explain the surface approaches, as well as to negatively predict the deep approaches to learning physics.     

Effects of extracurricular activities and their quality on primary school-age students’ achievement in mathematics in Switzerland

In this study, we examined the development of mathematics achievement in children attending extracurricular activities intensively in comparison with the development in a control group of children attending only the obligatory hours of school instruction. In addition, we investigated the question of possible effects of intensity of attendance and quality of extracurricular activities on achievement in students attending extracurricular activities from the end of Grade 1 to the end of Grade 3. This was a longitudinal study of a sample of N = 295 students in the first years of school at 35 primary schools in the German-speaking part of Switzerland. The results show that attendance in extracurricular activities had a positive effect on the development of students’ achievement. Students who attended extracurricular activities intensively in Grade 1, students who attended high-quality extracurricular activities, and especially those who did both, had greater improvement.     

University students’ perceptions of summative assessment: The role of context

We report on a mixed-method study that compared students’ perceptions of summative assessment across two distinct disciplines – education and mathematics, at two research-intensive institutions in the UK. The disciplines chosen represent opposing positions in Biglan’s classification of academic disciplines, as well as having very different assessment practices. Results suggest that these education students prefer to be assessed by methods they perceive to discriminate on the basis of academic abilities. Moreover, they perceive the traditional closed-book examination as inadequate to assess the capabilities which are key to being successful in their subject, which fits some but not all of the general findings in the literature. However, comparing these results with those of an identical study with mathematics students, we find that the perceptions of summative assessment are very different. We account for that difference by suggesting that students’ epistemic beliefs play a role in shaping these perceptions and conclude that, in designing summative assessment in higher education, generalised and centralised forces for change need to be tempered by contextual and disciplinary factors.
