Recently, researchers have demonstrated the benefits of technology-enhanced science inquiry activities. To improve students’ self-regulation and assist them in controlling their own learning pace through inquiry activities, in this study, a self-regulated science inquiry approach was developed to assist them in organizing information from their real-world exploration. A quasi-experimental design was conducted in an elementary school natural science course to evaluate the students’ performance using the proposed learning approach. One class assigned as the treatment group learned with the self-regulated science inquiry approach, while the other class assigned as the control group learned with the conventional science inquiry approach. The students’ learning achievement, tendency of information help seeking, tendency of self-regulation, and self-efficacy were evaluated. The results of the study revealed that the self-regulated science inquiry approach improved the students’ learning achievement, especially for those students with higher self-regulation. In addition, the students who conducted inquiry with the self-regulated learning strategy increased their tendency of information help seeking, self-efficacy, and several aspects of self-regulation, including time management, help seeking, and self-evaluation. Accordingly, this study demonstrated the effectiveness of the self-regulated learning strategy, an approach with high learner control, in terms of improving students’ learning achievement and their self-regulation.  相似文献

We present an inquiry‐based, aquatic science professional development (PD) for upper‐elementary, middle, and high school teachers and examine changes in student outcomes in light of participating teachers’ characteristics and the grade band of the students. Our study lends support to the assertion that inquiry‐ and content‐focused PD, paired with classroom implementation, can effectively improve student learning. Our findings indicate that students improved in their nature of science (NOS) and aquatic science content knowledge and that these changes depended in some ways on the participating teachers’ characteristics and adherence to the program. The students’ improvements were amplified when their teachers adhered more closely to the PD activities during their classroom implementation. The teachers’ previous science PD experience and pre‐PD understanding of inquiry‐based teaching also explained some of the variability in student growth. In both NOS and content, students of teachers with less prior science‐PD experience benefited more. Grade band also explained variation in student outcomes through interactions with teacher‐characteristic variables. In high school, students of teachers with lower pre‐PD inquiry knowledge appeared to learn more about NOS. Our results suggest that inquiry and content training through PD may minimize disparities in teaching due to inexperience and lack of expertise. Our study also demonstrates the value of PD that teaches a flexible approach to inquiry and focuses on underrepresented, interdisciplinary content areas, like aquatic science. © 2017 Wiley Periodicals, Inc.

In this paper, we investigate an approach to supporting students’ learning in science through a combination of physical experimentation and virtual modeling. We present a study that utilizes a scientific inquiry framework, which we call “bifocal modeling,” to link student-designed experiments and computer models in real time. In this study, a group of high school students designed computer models of bacterial growth with reference to a simultaneous physical experiment they were conducting, and were able to validate the correctness of their model against the results of their experiment. Our findings suggest that as the students compared their virtual models with physical experiments, they encountered “discrepant events” that contradicted their existing conceptions and elicited a state of cognitive disequilibrium. This experience of conflict encouraged students to further examine their ideas and to seek more accurate explanations of the observed natural phenomena, improving the design of their computer models.  相似文献

This study explored the use of wikis in a science inquiry-based project conducted with Primary 6 students (aged 11–12). It used an online wiki-based platform called PBworks and addressed the following research questions: (1) What are students’ attitudes toward learning with wikis? (2) What are students’ interactions in online group collaboration with wikis? (3) What have students learned with wikis in a science inquiry-based project in a primary school context? Analyses of the quantitative and qualitative data showed that with respect to the first research question, the students held positive attitudes toward the platform at the end of the study. With respect to the second research question, the students actively engaged in various forms of learning-related interactions using the platform that extended to more meaningful offline interactions. With respect to the third research question, the students developed Internet search skills, collaborative problem solving competencies, and critical inquiry abilities. It is concluded that a well-planned wiki-based learning experience, framed within an inquiry project-based approach facilitated by students’ online collaborative knowledge construction, is conducive to the learning and teaching of science inquiry-based projects in primary school.  相似文献

This study investigated the effects of a multi-pronged approach of increasing the nature of science (NOS) understandings of high school science students. The participants consist of 63 high school students: 31 in the intervention group and 32 in the control group. Explicit/reflective NOS instruction was imbedded within authentic inquiry experiences and supported by online discussions. The students in the intervention group were prompted to engage in various discussions focusing on essential tenets of NOS in an online environment that assured student confidentiality. NOS views were assessed through multiple data sources including pre- and post-intervention questionnaires as well as students’ responses to online discussion prompts. Results show that the instructional intervention used in this study which combined explicit/reflective NOS instruction with intense inquiry exposure along with ample reflective opportunities in an anonymous online discussion format led to positive learning gains in participants’ understanding the NOS aspects assessed. Implications for enhancing data collection with high school students and for promising professional development opportunities for science educators are discussed.  相似文献

ABSTRACT

Facilitating students’ deep-strategy behaviors and positive learning performances of science inquiry is an important and challenging educational issue. In this study, a contextual science inquiry approach is proposed for developing a 3D experiential game to cope with this problem. To evaluate the impacts of the game on students’ science learning approaches, learning achievements and problem-solving awareness as well as the learning behavioral patterns of the students with different learning achievements, a quasi-experiment was conducted in an elementary school geoscience course. The participants were two classes of sixth graders. One class was the experimental group who learned with the 3D experiential game, and the other was the control group who learned with the conventional technology-enhanced learning approach. The experimental results showed that the students learning with the 3D experiential gaming system showed better learning achievements, problem-solving tendency, deep learning strategies, and deep learning motive than those who learned with the conventional technology-enhanced learning approach. Moreover, the higher-achievement students showed more behavioral patterns of deep learning strategies than the lower-achievement students. The findings of this study provide a good reference for helping lower-achievement students improve their learning performance.  相似文献

This study examines how an inquiry-based approach to teaching and learning creates teachable moments that can foster conceptual understanding in students, and how teachers capitalize upon these moments. Six elementary school teachers were videotaped as they implemented an integrated inquiry-based science and literacy curriculum in their classrooms. In this curriculum, science inquiry implies that students search for evidence in order to make and revise explanations based on the evidence found and through critical and logical thinking. Furthermore, the curriculum material is designed to address science key concepts multiple times through multiple modalities (do it, say it, read it, write it). Two types of teachable moments were identified: planned and spontaneous. Results suggest that the consolidation phases of inquiry, when students reinforce new knowledge and connect their empirical findings to theory, can be considered as planned teachable moments. These are phases of inquiry during which the teacher should expect, and be prepared for, student utterances that create opportunities to further student learning. Spontaneous teachable moments are instances when the teacher must choose to either follow the pace of the curriculum or adapt to the students’ need. One implication of the study is that more teacher support is required in terms of how to plan for and effectively utilize the consolidation phases of inquiry.  相似文献

The paper traces a research process in the design and development of a science learning environment called WiMVT (web-based inquirer with modeling and visualization technology). The WiMVT system is designed to help secondary school students build a sophisticated understanding of scientific conceptions, and the science inquiry process, as well as develop critical learning skills through model-based collaborative inquiry approach. It is intended to support collaborative inquiry, real-time social interaction, progressive modeling, and to provide multiple sources of scaffolding for students. We first discuss the theoretical underpinnings for synthesizing the WiMVT design framework, introduce the components and features of the system, and describe the proposed work flow of WiMVT instruction. We also elucidate our research approach that supports the development of the system. Finally, the findings of a pilot study are briefly presented to demonstrate of the potential for learning efficacy of the WiMVT implementation in science learning. Implications are drawn on how to improve the existing system, refine teaching strategies and provide feedback to researchers, designers and teachers. This pilot study informs designers like us on how to narrow the gap between the learning environment’s intended design and its actual usage in the classroom.  相似文献

Based on the cognitive-affective theory, the present study designed a science inquiry learning model, predict-observe-explain (POE), and implemented it in an app called “WhyWhy” to examine the effectiveness of students’ science inquiry learning practice. To understand how POE can affect the cognitive-affective learning process, as well as the learning progress, a pretest and a posttest were given to 152 grade 5 elementary school students. The students practiced WhyWhy during six sessions over 6 weeks, and data related to interest in learning science (ILS), cognitive anxiety (CA), and extraneous cognitive load (ECL) were collected and analyzed through confirmatory factor analysis with structure equation modeling. The results showed that students with high ILS have low CA and ECL. In addition, the results also indicated that students with a high level of self-confidence enhancement showed significant improvement in the posttest. The implications of this study suggest that by using technology-enhanced science learning, the POE model is a practical approach to motivate students to learn.  相似文献

A considerable body of evidence highlights how inquiry-based science can enhance students' epistemic and conceptual understanding of scientific concepts, principles, and theories. However, little is known about how students view themselves as learners of science. In this paper, we explore primary children's images of doing science in school and how they compare themselves with ‘real’ scientists. Data were collected through the use of a questionnaire, drawing activity, and interviews from 161 Grade 4 (ages 9–10) students in Singapore. Results indicate that ‘doing science as conducting hands-on investigations’, ‘doing science as learning from the teacher’, ‘doing science as completing the workbook’, and ‘doing science as a social process’ are the images of learning science in school that most of the students held. In addition, students reported that they need to be well behaved first and foremost, while scientists are more likely to work alone and do things that are dangerous. Moreover, students often viewed themselves as ‘acting like a scientist’ in class, especially when they were doing experiments. Nevertheless, some students reported that they were unlike a scientist because they believed that scientists work alone with dangerous experiments and do not need to listen to the teacher and complete the workbook. These research findings further confirm the earlier argument that young children can make distinctions between school science and ‘real’ science. This study suggests that the teaching of science as inquiry and by inquiry will shape how students view their classroom experiences and their attitudes towards science.  相似文献

Science learning is inextricably tied to two aspects of students’ lives: literacy and culture. While English Learners (ELs) who speak a non-English native language are typically the focus in this line of scholarly inquiry, deaf and hard-of-hearing (DHH) students occupy a distinct space in this conversation. For DHH learners, literacy levels can be hindered by an early dependence on a more survival-based language learning model that postpones basic scientific inquiry. The vocabulary for curiosity is limited, which in turn affects the educational culture. DHH learners have a unique culture that demands an appropriate science curriculum, which thus far has not been explored or attempted for either DHH learners or their educators. Data collected consisted of interviews with teachers of DHH students, as well as observational data collected from a high-minority urban K-8 school for DHH students. The analysis revealed that, first, many of the teachers had limited preparation to teach science content. Second, DHH teachers used inconsistent instructional strategies ranging from drawing pictures to building models. Third, the modifications provided to DHH science learners were mostly limited to visual support and repetition. Implications for teacher education programs include instruction focused on specific supports for DHH students and co-teaching methods, and deeper investigation of inquiry-based science practices. Implications for classroom practices include providing hands-on, inquiry-based instruction, working closely with parents, and developing students’ and teachers’ understanding of scientific inquiry.

Grounded in Hallidayan perspectives on academic language, we report on our development of an educative science assessment as one component of the language-rich inquiry science for English-language learners teacher professional learning project for middle school science teachers. The project emphasizes the role of content-area writing to support teachers in diagnosing their students’ emergent understandings of science inquiry practices, science content knowledge, and the academic language of science, with a particular focus on the needs of English-language learners. In our current school policy context, writing for meaningful purposes has received decreased attention as teachers struggle to cover large numbers of discrete content standards. Additionally, high-stakes assessments presented in multiple-choice format have become the definitive measure of student science learning, further de-emphasizing the value of academic writing for developing and expressing understanding. To counter these trends, we examine the implementation of educative assessment materials—writing-rich assessments designed to support teachers’ instructional decision making. We report on the qualities of our educative assessment that supported teachers in diagnosing their students’ emergent understandings, and how teacher–researcher collaborative scoring sessions and interpretation of assessment results led to changes in teachers’ instructional decision making to better support students in expressing their scientific understandings. We conclude with implications of this work for theory, research, and practice.  相似文献

As secondary students’ interest in science is decreasing, schools are faced with the challenging task of providing adequate instruction to engage students—and more particularly the disadvantaged students—to learn science and improve their science inquiry skills. In this respect, the integration of Web-based collaborative inquiry can be seen as a possible answer. However, the differential effects of Web-based inquiry on disadvantaged students have barely been studied. To bridge this gap, this study deals with the implementation of a Web-based inquiry project in 19 secondary classes and focuses specifically on gender, achievement level, and academic track. Multilevel analysis was applied to uncover the effects on knowledge acquisition, inquiry skills, and interest in science. The study provides quantitative evidence not only that a Web-based collaborative inquiry project is an effective approach for science learning, but that this approach can also offer advantages for students who are not typically successful in science or who are not enrolled in a science track. This approach can contribute to narrowing the gap between boys and girls in science and can give low-achieving students and general-track students an opportunity to develop confidence and skills for learning science, bringing them to a performance level that is closer to that of high-achieving students.  相似文献

Abstract

This exploratory study aimed to describe the impact of the ‘Science in Family project’, as a transformative learning model for science teachers trying to improve student’s attitudes toward STEM subjects. This study took place in a public elementary school in Monterrey, Mexico, which has been developing this project for more than thirteen years with students from 4th, 5th and 6th grade. We used participant observation and interviews with four families whose children are students of this elementary school, and with one family whose sons were students of this school some years ago. Results showed that there is a relationship between positive attitudes towards science in students who were exposed to transformative learning models of teaching. Two of the participants took steps to follow science related careers. This study helps to illuminate the extent to which teacher education models influence students’ attitudes and how positive attitudes to science are influenced by the use of learning by doing projects.  相似文献

In order to promote scientific inquiry in secondary schooling in Taiwan, the study developed a computer-based inquiry curriculum (including structured and guided inquiry units) and investigated how the curriculum influenced students’ science learning. The curriculum was implemented in 5 junior secondary schools in the context of a weeklong summer science course with 117 students. We first used a multi-level assessment approach to evaluate the students’ learning outcomes with the curriculum. Then, a path analysis approach was adopted for investigating at different assessment levels how the curriculum as a whole and how different types of inquiry units affected the students’ development of conceptual understandings and inquiry abilities. The results showed that the curriculum was effective in enhancing the students’ conceptual knowledge and inquiry abilities in the contexts of the six scientific topics. After the curriculum, they were able to construct interconnected scientific knowledge. The path diagrams suggested that, due to different instructional designs, the structured and guided inquiry units appeared to support the students’ learning of the topics in different ways. More importantly, they demonstrated graphically how the learning of content knowledge and inquiry ability mutually influenced one another and were reciprocally developed in a computer-based inquiry learning environment.  相似文献

The purpose of this study is to investigate how three teachers guided their students to learn science using interactive dynamic visualizations incorporated in an inquiry digital unit. The results show that the teachers’ guidance varied in frequency, occasion, and content type. Each teacher demonstrated a different instructional approach in terms of the two dimensions of facilitating versus informing, and responsive, norm-revealing inquiry guidance versus planned, meaning-defining inquiry guidance. The study illustrates the range of inquiry instruction supporting learning with interactive dynamic visualizations. Moreover, the teacher effect was significant on the students’ learning outcomes when instructional time and the students’ pre-test scores were controlled using a multiple regression model. Effective teaching strategies that augment students’ integrated understanding of science phenomena through interactive dynamic visualizations are discussed based on the association between teaching effects and learning outcomes.  相似文献

This study explores the reflective processes by which a grade 5 science community co-constructed shared inquiry structures to focus and guide its inquiry about human body systems over a school year supported by a collaborative online environment. The co-constructed structures included a list of collective wondering areas as the shared focus of inquiry and models of the inquiry process in the form of “research cycle.” Qualitative analyses of field notes, classroom videos, student notebooks and interviews elaborate the evolution of the inquiry areas and the “research cycle” model as well as students’ adaptive use of the structures to guide deeper inquiry. Content analyses of students’ individual research questions and collaborative online discourse indicate that students used the structures to develop more advanced inquiry and make productive contributions. The results contribute to elaborating a reflective structuration approach to co-organizing and sustaining long-term, open-ended inquiry in knowledge building communities.  相似文献

Recent research reveals that students' interest in school science begins to decline at an early age. As this lack of interest could result in fewer individuals qualified for scientific careers and a population unprepared to engage with scientific societal issues, it is imperative to investigate ways in which interest in school science can be increased. Studies have suggested that inquiry learning is one way to increase interest in science. Inquiry learning forms the core of the primary syllabus in Singapore; as such, we examine how inquiry practices may shape students' perceptions of science and school science. This study investigates how classroom inquiry activities relate to students' interest in school science. Data were collected from 425 grade 4 students who responded to a questionnaire and 27 students who participated in follow-up focus group interviews conducted in 14 classrooms in Singapore. Results indicate that students have a high interest in science class. Additionally, self-efficacy and leisure-time science activities, but not gender, were significantly associated with an increased interest in school science. Interestingly, while hands-on activities are viewed as fun and interesting, connecting learning to real-life and discussing ideas with their peers had a greater relation to student interest in school science. These findings suggest that inquiry learning can increase Singaporean students' interest in school science; however, simply engaging students in hands-on activities is insufficient. Instead, student interest may be increased by ensuring that classroom activities emphasize the everyday applications of science and allow for peer discussion.  相似文献

Generations of students are graduating from secondary school disinterested in post-secondary study of science or pursuing careers in science-related fields beyond formal education. We propose that destabilising such disinterest among future students requires science educators to begin listening to secondary school students regarding their views of how science learning is made interesting within the science classroom. Studies on students’ interest in response to instructional strategies applied in the classroom communicate the opinions (i.e. the ‘voice’) of students about the strategies they believe make their classroom learning interesting. To this end, this scoping study (1) collects empirical studies that present from various science and non-science academic domains students’ views about how to make classroom learning interesting; (2) identifies common instructional strategies across these domains that make learning interesting; and (3) forwards an instructional framework called TEDI ([T]ransdisciplinary Connections; Mediated [E]ngagement; Meaningful [D]iscovery; and Self-determined [I]nquiry), which may provide secondary school science teachers with a practical instructional approach for making learning science genuinely interesting among their students within the secondary school science classroom context.  相似文献
