Students' emotions during homework: Structures,self-concept antecedents,and achievement outcomes

In the present study (N = 553; 8th and 11th grade students; 52% female) we investigated students' enjoyment, pride, anxiety, anger, and boredom while completing homework (homework emotions), and contrasted these emotions with those experienced during class (classroom emotions). Both homework emotions and classroom emotions were assessed separately for the domains of mathematics, physics, German, and English. Our hypotheses were based on propositions of the control-value theory of achievement emotions (Pekrun, 2006), Marsh and Ayotte's (2003) differential distinctiveness hypothesis, and previous empirical findings. In line with our assumptions, observed correlations between homework emotions and classroom emotions suggested that the emotions experienced in the two settings should be assessed separately. Within domains, both homework emotions and classroom emotions showed clear linkages with students' academic self-concept and achievement outcomes, with self-concept being slightly more strongly related to classroom emotions. Between-domain relations of emotions were significantly stronger for homework emotions as compared to classroom emotions, likely due to the relative situational homogeneity of homework settings across domains. Further, between-domain relations for emotions in both settings were weaker in 11th grade students, whereas within-domain relations did not differ as a function of age. Implications for research and educational practice are discussed.

The interplay of representations and patterns of classroom discourse in science teaching sequences

The purpose of this study is to examines the relationship between the communicative approach of classroom talk and the modes of representations used by science teachers. Based on video data from two physics classrooms in Singapore, a recurring pattern in the relationship was observed as the teaching sequence of a lesson unfolded. It was found that as the mode of representation shifted from enactive (action based) to iconic (image based) to symbolic (language based), there was a concurrent and coordinated shift in the classroom communicative approach from interactive–dialogic to interactive–authoritative to non-interactive–authoritative. Specifically, the shift from enactive to iconic to symbolic representations occurred mainly within the interactive–dialogic approach while the shift towards the interactive–authoritative and non-interactive–authoritative approaches occurred when symbolic modes of representation were used. This concurrent and coordinated shift has implications on how we conceive the use of representations in conjunction with the co-occurring classroom discourse, both theoretically and pedagogically.     

Pedagogical Affordances of Multiple External Representations in Scientific Processes

Multiple external representations (MERs) have been widely used in science teaching and learning. Theories such as dual coding theory and cognitive flexibility theory have been developed to explain why the use of MERs is beneficial to learning, but they do not provide much information on pedagogical issues such as how and in what conditions MERs could be introduced and used to support students?? engagement in scientific processes and develop competent scientific practices (e.g., asking questions, planning investigations, and analyzing data). Additionally, little is understood about complex interactions among scientific processes and affordances of MERs. Therefore, this article focuses on pedagogical affordances of MERs in learning environments that engage students in various scientific processes. By reviewing literature in science education and cognitive psychology and integrating multiple perspectives, this article aims at exploring (1) how MERs can be integrated with science processes due to their different affordances, and (2) how student learning with MERs can be scaffolded, especially in a classroom situation. We argue that pairing representations and scientific processes in a principled way based on the affordances of the representations and the goals of the activities is a powerful way to use MERs in science education. Finally, we outline types of scaffolding that could help effective use of MERs including dynamic linking, model progression, support in instructional materials, teacher support, and active engagement.

Effects of Animations in Learning—A Cognitive Fit Perspective1

Information technology (IT) artifacts such as animations are increasingly used in educational institutions. Researchers caution that, if we are to derive benefits from animations and other such IT artifacts, we must understand how to use it optimally. In this study, we look at the effects of animations in supporting learning processes. IT‐enabled animations dynamically depict changes in events and are used in the classroom as external representations to elaborate on the knowledge content transferred in the classroom. Research in related disciplines has investigated the effects of using these animations on student learning outcomes and has reported conflicting results. We propose that the theory of cognitive fit in information systems could reconcile these conflicting findings and offer some insight into how these animations might be used most beneficially. We conduct laboratory‐based experiments to test our ideas. Our findings indicate that these representations are superior to text‐based representations and reduce students' cognitive load only in learning tasks where animations have a good cognitive fit. We discuss the implications of our findings for the use of animations and other external representations in the classroom and for future research on the role of Technology Mediated Learning.     

Representing the Electromagnetic Field: How Maxwell��s Mathematics Empowered Faraday��s Field Theory

James Clerk Maxwell ??translated?? Michael Faraday??s experimentally-based field theory into the mathematical representation now known as ??Maxwell??s Equations.?? Working with a variety of mathematical representations and physical models Maxwell extended the reach of Faraday??s theory and brought it into consistency with other results in the physics of electricity and magnetism. Examination of Maxwell??s procedures opens many issues about the role of mathematical representation in physics and the learning background required for its success. Specifically, Maxwell??s training in ??Cambridge University?? mathematical physics emphasized the use of analogous equations across fields of physics and the repeated solving of extremely difficult problems in physics. Such training develops an array of overlearned mathematical representations supported by highly sophisticated cognitive mechanisms for the retrieval of relevant information from long term memory. For Maxwell, mathematics constituted a new form of representation in physics, enhancing the formal derivational and calculational role of mathematics and opening a cognitive means for the conduct of ??experiments in the mind?? and for sophisticated representations of theory.     

Encouraging and analyzing student questions in a large physics course: Meaningful patterns for instructors

In a large introductory physics course, structured weekly journals (weekly reports) regularly encouraged students to ask questions about the material. The resulting questions were collected for one quarter and coded based on difficulty and topic. Students also took several conceptual tests during the quarter. The reports contained more questions than typically observed in a college classroom, but the number of questions asked was not correlated to any measure of conceptual performance. Relationships among different types of questions and performance on these tests were explored. Deeper‐level questions that focus on concepts, coherence of knowledge, and limitations were related to the variance in student conceptual achievement. © 2003 Wiley Periodicals, Inc.

Cooperative learning,motivational effects,and student characteristics: An experimental study comparing cooperative learning and direct instruction in 12th grade physics classes

One hundred thirty-seven students in 12th grade physics classes participated in a quasi-experimental study comparing the jigsaw classroom method of cooperative instruction with traditional direct instruction. While no differences were found between the two conditions for physics achievement gains, the results revealed differences in students' experience of the three basic needs (autonomy, competence, and social relatedness as posited by self-determination theory of learning), in self-reported cognitive activation, and in degree of intrinsic motivation. Path analyses showed that the basic needs partially mediated the effects of method of instruction on cognitive activation and intrinsic motivation. Increases in feelings of competence with cooperative learning were associated with better performance in physics. When controlling for competence, however, direct instruction had a facilitating effect on physics performance. Four aspects of students' personal learning characteristics (previous knowledge, academic self-concept in physics, academic goal orientation, uncertainty orientation) were assessed. Method of instruction was found to interact with self-concept: students with low academic self-concept profited more from cooperative instruction than from direct instruction because they experienced a feeling of greater competence.     

Fictive kinship as it mediates learning, resiliency, perseverance, and social learning of inner-city high school students of color in a college physics class

In this hermeneutic study we explore how fictive kinship (kin-like close personal friendship) amongst high school students of color mediated their resiliency, perseverance, and success in a college physics class. These freely chosen, processual friendships were based on emotional and material support, motivation, and caring for each other, as well as trust, common interests, and goals. Such close bonds contributed in creating a safe and supportive emotional space and allowed for friendly, cooperative competition within the physics classroom. Friends became the role models, source of support, and motivation for the fictive kinship group as well as for each other, as the group became the role model, source of support, and motivation for the individuals in it. Because of their friendships with one another, physics talk was extended and made part of their personal interactions outside the classroom. These social relationships and safe spaces helped the students cope and persevere despite their initial conflicting expectations of their success in physics. Our research thus expands on the concept of social learning by exploring student friendships and how they frame and mediate such a process.     

Motivational goal orientation, perceptions of biology and physics classroom learning environments, and gender

Researchers have reported persuasive evidence that students?? perceptions of their classroom learning environment account for significant variance in cognitive and affective outcomes (e.g. intrinsic motivation, self-concept, liking for particular subjects and students?? intention to drop out). The study reported in this paper investigated the relationship between students?? perceptions of classroom learning environment and motivational achievement goal orientations towards biology and physics, as well as the influence of gender. Participants (N?=?1538) were high school science students from the north-eastern region of Thailand. Our results suggest that motivational goals are linked to differences in students?? perceptions of learning environment and levels of biology and physics classroom anxiety. We found that females adopted significantly higher levels of mastery and performance approach goals towards biology, while males adopted significantly higher levels of mastery and performance approach goals towards physics. Males adopted significantly higher levels of performance avoidance goals towards both biology and physics. Positive associations emerged between gender and the adoption of specific performance goals, perceived degree of competition in biology and physics classrooms, and levels of biology and physics classroom anxiety. These results suggest that motivational goal orientations and perceptions of learning environment are gender-dependent and domain-specific for the two science content areas.

Motivation and learning physics

Being involved in science education we cannot avoid confronting the problem of students' waning interest in physics. Therefore, we want to focus on arguments developed by new theoretical work in the field of motivation. Especially, we are attracted by the theory of motivation featured by Deci and Ryan, because it is related to an assumptions of human development similar to our own approach. Beneath elements of cognitive development, motivation is seen as a basic concept to describe students' learning in a physics classroom. German students at lower and upper secondary level regard physics as very difficult to learn, very abstract and dominated by male students. As a result physics at school continuously loses importance and acceptance although a lot of work has been done to modernise and develop the related physics courses. We assume that knowing about the influence of motivation on learning physics may lead to new insights in the design of classroom settings. Referring to Deci and Ryan, we use a model of motivation to describe the influence of two different teaching strategies (teacher and discourse oriented) on learning. Electrostatics was taught in year 8. The outcomes of a questionnaire which is able to evaluate defined, motivational states are compared with the interpretation of the same student's interaction in the related situation of the physics classroom. The scales of the questionnaire and the categories of analysis of the video-recording are derived from the same model of motivation.     

Evaluation of a Theory of Instructional Sequences for Physics Instruction

The background of the study is the theory of basis models of teaching and learning, a comprehensive set of models of learning processes which includes, for example, learning through experience and problem‐solving. The combined use of different models of learning processes has not been fully investigated and it is frequently not clear under what circumstances a particular model should be used by teachers. In contrast, the theory under investigation here gives guidelines for choosing a particular model and provides instructional sequences for each model. The aim is to investigate the implementation of the theory applied to physics instruction and to show if possible effects for the students may be attributed to the use of the theory. Therefore, a theory‐oriented education programme for 18 physics teachers was developed and implemented in the 2005/06 school year. The main features of the intervention consisted of coaching physics lessons and video analysis according to the theory. The study follows a pre‐treatment‐post design with non‐equivalent control group. Findings of repeated‐measures ANOVAs show large effects for teachers' subjective beliefs, large effects for classroom actions, and small to medium effects for student outcomes such as perceived instructional quality and student emotions. The teachers/classes that applied the theory especially well according to video analysis showed the larger effects. The results showed that differentiating between different models of learning processes improves physics instruction. Effects can be followed through to student outcomes. The education programme effect was clearer for classroom actions and students' outcomes than for teachers' beliefs.     

Student,teacher, and instructional characteristics related to students' gains in flexibility

Flexibility in problem solving has been widely recognized as an important skill for students' mastery of mathematics. Here we utilize the Opportunity-Propensity framework to investigate student characteristics, teacher characteristics, and teacher instructional practices that may be associated with students' gains in flexibility in algebra. Teacher and student data were collected from 8th and 9th grade Algebra I teachers in Massachusetts as part of a larger study on the impact of a researcher-developed year-long supplementary curriculum that focused on improving students' flexibility. We explore student demographics, teacher background characteristics and teacher instructional practices as predictors of student gains in flexibility. We further investigate instructional practices associated with flexibility gains through an analysis of teacher questioning in the classroom for teachers whose students achieved the greatest gains in flexibility and those whose students achieved the least gains. Our results indicate that prior knowledge is a reliable predictor of flexibility gains and that gender is an important student background characteristic associated with the development of flexibility. In addition, although high and low gain teachers did not differ in their implementation fidelity, high flexibility gain teachers asked more open-ended questions that prompted students to verbalize the main ideas of the lesson.     

Survey of classroom use of representations: development,field test and multilevel analysis

Because of the multimodal nature of learning, doing and reporting science, it is important that students learn how to interpret, construct, relate and translate scientific representations or, in other words, to develop representational competence. Explicit instruction about multimodal representations is needed to foster students’ representational competence in the classroom. However, only a handful studies have surveyed how representations are actually used in science classes. This might be because of the fact that economical instruments for assessing the use of representations in classrooms are not available. To bridge that gap, an instrument was developed, field-tested in biology classes with 175 and 931 students, respectively, and analysed using exploratory and (multilevel) confirmatory factor analyses. Results supported an instrument with six scales and 21 items at the individual and classroom levels covering the following dimensions: (1) interpretation of visual representations, (2) construction of visual representations, (3) use of scientific texts (verbal representations), (4) use of symbolic representations, (5) number of terms used in class, and (6) the extent to which active social construction of knowledge is possible in the class. The scales showed satisfactory discriminant validity and reliability at each level. Further applications of this instrument for researchers and teachers are discussed.
