This study explores how often students are engaged in their science classes and their affective states during these times, using an innovative methodology that records these experiences in situ. Sampling a subset of high schools in the U.S. and Finland, we collected over 7,000 momentary responses from 344 students over the course of a week. We examine engagement within and between students in different environments identifying common social and emotional factors they may be experiencing in their science classes, suggesting the challenges that the U.S. and Finland may encounter when implementing their new science standards (i.e., Next Generation of Science Standards and Finnish National Core Curriculum). We operationalize engagement as situational when students experience high levels of challenge, skill, and interest, which we term as optimal learning moments. Specifically we analyze: (i) the components of optimal learning; (ii) the relationship of optimal learning with other subjective measures; (iii) how optimal learning moments in science classes compare to other academic classes; and (iv) the extent that optimal learning moments predict an individual's perception of importance to self and future in science classes. Using several multivariate models, results show that when students are challenged in their classes and are appropriately skilled they are more likely to feel confident, successful, and happy during specific science classes as well as in other academic classes. When students experience more times of optimal learning in their science classes they are more likely to report that they perceive science as important to them and their futures. Females, however, report being more stressed in their science classes than males. # 2015 Wiley Periodicals, Inc.
Recently, there has been critiques towards science education research, as the potential of this research has not been actualised in science teaching and learning praxis. The paper describes an analysis of a design-based research approach (DBR) that has been suggested as a solution for the discontinuation between science education research and praxis. We propose that a pragmatic frame helps to clarify well the design-based research endeavour. We abstracted three aspects from the analysis that constitute design-based research: (a) a design process is essentially iterative starting from the recognition of the change of the environment of praxis, (b) it generates a widely usable artefact, (c) and it provides educational knowledge for more intelligible praxis. In the knowledge acquisition process, the pragmatic viewpoint emphasises the role of a teacher’s reflected actions as well as the researches’ involvement in the authentic teaching and learning settings.
This study seeks to understand how different scientific practices in high school science classrooms are associated with student situational engagement. In this study, situational engagement is conceptualized as the balance between skills, interest, and challenge when the reported experiences are all high. In this study, data on situational engagement were collected using the experience sampling method (ESM) from 142 students in southern Michigan (the United States), resulting 993 ESM responses, and 133 students in southern Finland, resulting 1,351 responses. In both countries, scientific practices related to developing models and constructing explanations were associated with higher student situational engagement than other practices. In southern Finland, using a model was also associated with a high level of student situational engagement. The results indicate that students may experience situational engagement more often in science classrooms that use models than those that do not employ such practices. Thus, scientific practices related to models should be used frequently in science ---This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
Students find science relevant to society, but they do not find school science interesting. This survey study analyzes Finnish grade 9 students' actual experiences with science teaching methods and their preferences for how they would like to study science. The survey data were collected from 3,626 grade 9 students (1,772 girls and 1,832 boys) across randomly sampled secondary schools. Students were asked to evaluate how often a particular teaching method is used in science (chemistry and physics) teaching and how often they would like to see the teaching method used. Data were analyzed using nonparametric tests. Boys seemed to be more satisfied with current and traditional science teaching methods like direct teaching, solving basic problems, reading textbooks, and conducting practical work, while girls desired more discussion. Students who are interested in school science or think that school science is relevant in everyday life would like more creative activities such as brainstorming and project work. Results indicated that understanding the connection between student interest and teaching method preferences, especially interpreting interested students' desire for creative activities, are important aspects for future research.
The aim of this study was to design a novel and holistic way to teach chemical bonding at the middle school level according to research on the teaching and learning of bonding. A further aim was to investigate high achieving middle school students' conceptual structures concerning chemical bonding by using a systemic perspective. Students in one metropolitan area middle school were introduced to this newly designed model and their conceptual structures were studied by a clinical interview (n= 8) at the time when the students were concluding their studies at the middle school. The interview data were analysed by employing a systemic perspective on conceptual structures. Elements of conceptual structures such as concepts, simple models (mnemonic devices), explaining schemas, attributes and hypothesis constructs were identified and coded. Connections between the knowledge elements were also identified. An understanding of these connections helps to illuminate which components are necessary to build an adequate conceptual structure. The study revealed that applying principles relating to Coulombic interaction to understand chemical bonding requires the simultaneous appreciation of several factors: First, electron shells have to be understood in terms of energy levels. Second, the distance between the outer electrons and the nucleus has to be understood on the basis of electron shell construction. On the other hand, the effective nuclear charge also needs to be taken into account. The study introduces two new points of view to chemistry education research (CER): (1) a teaching model of chemical bonding that emphasises electric interaction as the background of most bonding types was developed in the study. This responds to the identified need in CER to test alternative teaching models that avoid the octet framework. (2) In the field of chemistry education research, a systemic approach has not previously been widely used for the examination of conceptual structures. In addition, the systemic perception of the network structure, which consists of these constructions, helps to explain in more detail the relationship between the separate concepts and the constructions and their significance as a whole.
