ABSTRACTGraduate students regularly teach undergraduate STEM courses and can positively impact students’ understanding of science. Yet little research examines graduate students’ knowledge about nature of science (NOS) or instructional strategies for teaching graduate students about NOS. This exploratory study sought to understand how a 1-credit Teaching in Higher Education course that utilised an explicit, reflective, and mixed-context approach to NOS instruction impacted STEM graduate students’ NOS conceptions and teaching intentions. Participants included 13 graduate students. Data sources included the Views of Nature of Science (VNOS-Form C) questionnaire administered pre- and post-instruction, semi-structured interviews with a subset of participants, and a NOS-related course project. Prior to instruction participants held many alternative NOS conceptions. Post-instruction, participants’ NOS conceptions improved substantially, particularly in their understandings of theories and laws and the tentative nature of scientific knowledge. All 12 participants planning to teach NOS intended to use explicit instructional approaches. A majority of participants also integrated novel ideas to their intended NOS instruction. These results suggest that a teaching methods course for graduate students with embedded NOS instruction can address alternative NOS conceptions and facilitate intended use of effective NOS instruction. Future research understanding graduate students' NOS understandings and actual NOS instruction is warranted. 相似文献

In this study, the author implemented a problem-based learning (PBL) experience that allowed students in an advanced science
methodology course to explore differentiated instruction. Through working systematically in small, collaborative groups, students
explored the nature of differentiated instruction. The objective of the study was to examine pre-service teachers’ developing
conceptions of differentiated instruction (DI) as a way to teach for diversity. The author adopted action research as a strategy
to explore students’ perceptions of DI in the context of science teaching and learning. Several data collection methods and
sources were adopted in the study, including student-generated products, student interviews, classroom observation, and journal
writing. Outcomes report on students’ perceptions of both the potential and challenges associated with adopting a DI approach
to science teaching and learning. 相似文献

This study examines the influence of laboratory instruction that engages students in a wide range of the practices of science on Turkish high-school students’ chemistry learning. In this mixed methods study, student learning in two different laboratory settings was compared, one that featured an instruction that engaged students in a wide range of disciplinary practices (through Argument-driven Inquiry – ADI) and similar laboratories in which a more traditional Structured Inquiry (SI) approach was employed. The data sources included a Chemistry Concept test, an Argumentative Writing Assessment, and Semi-structured interviews. After seven weeks of chemistry instruction, students experiencing ADI instruction scored higher on the Chemistry Concept test and the Argumentative Writing Assessment than students experiencing SI instruction. Furthermore, girls who experienced ADI instruction scored higher on the assessments than their majority peers in the same class. The results suggest that Turkish students can substantially improve their chemistry proficiency if they have an opportunity to engage in instruction featuring a broad array of the practices of science. 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

ABSTRACTBackground: As inquiry-based instruction is not universally implemented in science classrooms, it is crucial to introduce instructional strategies through the use of contextualized learning activities to allow students with different background knowledge and abilities to learn the essential competencies of scientific inquiry and promote their emotional perception and engagement.Purpose: This study explores how essential scientific competencies of inquiry can be integrated into classroom teaching practices and investigates both typical and gifted secondary students’ emotional perception and engagement in learning activities.Sample: A case teacher along with 226 typical and 18 gifted students from a suburban secondary school at Taiwan participated in this study.Design and methods: After attending twelve 3-hour professional development workshops that focused on scientific inquiry teaching, the case teacher voluntarily developed and elaborated her own teaching activities through the discussions and feedback that she received from workshop participants and science educators. Quantitative and qualitative data were collected through activity worksheet, questionnaire, video camera, and tape recorders. Frequency distribution, Mann-Whitney U test, and discourse analysis were used for data analyses.Results: Case teacher’s teaching activities provide contextual investigations that allow students to practice making hypotheses, planning investigations, and presenting and evaluating findings. Students’ learning outcomes reveal that typical students can engage in inquiry-based learning with positive emotional perception as well as gifted students regardless of their ability level. Both gifted and typical students’ positive emotional perception of and active engagement in learning provide fresh insight into feasible instructions for teachers who are interested in inquiry-based teaching but have little available time to implement such instructions into their classrooms.Conclusions: The results of our work begin to address the critical issues of inquiry-based teaching by providing an exemplary teaching unit encompassing essential scientific competencies 相似文献

Abstract The effects of students' conceptual levels and teachers' instruction patterns on students' motivation to learn academic course content were investigated. An examination of 63 students enrolled in a course entitled “Motivation and Performance in Organizations” at West Point yielded statistically significant interactions: For low-conceptual-level students, direct teaching methods maximize motivation to learn course content; for high-conceptual-level students, nondirect instruction significantly enhances motivation. These results expand existing educational literature that suggests that proper conceptual level/instruction pattern matches enhance students' motivation in the classroom. Educators may use this knowledge to develop teaching environments that support the specific learning needs of individual students. 相似文献

Involving students in the co-design of educational curricula and practices can benefit both students and teachers. Students who participate in co-design may show better learning or increased agency or engagement. In the present study, we investigated what kind of science knowledge or practices can be learned by student co-designers while engaging in co-design practices and how that learning happens with six high school students. We created a model to guide the analysis of students’ learning with technology in co-designing processes. The results revealed that students learned engineering design process even if no explicit instruction on engineering learning was given. Also, our analysis suggested that co-designing with technology enabled learning of the engineering design process and potentially furthered learning of science because it promoted knowledge integration. The results have implications for understanding and enhancing engineering design and science learning through co-designing with technology.

The implementation of science reform must be viewed as a systems-level problem and not just focus on resources for teachers and students. High-capacity instructional leadership is essential for supporting classroom science instruction. Recent reform efforts include a shift from learning about science facts to figuring out scientific phenomena in which students use science practices as they build and apply disciplinary core ideas. We report findings from a research study on professional development (PD) to support instructional leaders' learning about the science practices. After participating in the PD, the instructional leaders' familiarity with and leadership content knowledge of the science practices significantly improved. Initially, principals used their understandings from other disciplines and content neutral visions of classrooms to make sense of science instruction. For example, they initially used their understandings of models and argument from ELA and math to make sense of science classroom instruction. Furthermore, some principals focused on content neutral strategies, like a clear objective. Over the course of the PD workshops, principals took up the language of the science practices in more nuanced and sophisticated ways. Principals' use of the language of the science practices became more frequent and shifted from identifying or defining them to considering quality and implementation in science classrooms. As we design tools to support science, we need to consider instructional leaders as important stakeholders and develop resources to specifically meet their needs. If the science feels too unfamiliar or intimidating, principals may avoid or reframe science reform efforts. Consequently, it is important to leverage instructional leaders' resources from other disciplines and content neutral strategies as bridges for building understanding in science. We argue that the science practices are one potential lever to engage in this work and shift instructional leaders' understandings of science instruction. 相似文献

In this study, we used targeted active-learning activities to help students improve their ways of reasoning about carbon flow in ecosystems. The results of a validated ecology conceptual inventory (diagnostic question clusters [DQCs]) provided us with information about students' understanding of and reasoning about transformation of inorganic and organic carbon-containing compounds in biological systems. These results helped us identify specific active-learning exercises that would be responsive to students' existing knowledge. The effects of the active-learning interventions were then examined through analysis of students' pre- and postinstruction responses on the DQCs. The biology and non-biology majors participating in this study attended a range of institutions and the instructors varied in their use of active learning; one lecture-only comparison class was included. Changes in pre- to postinstruction scores on the DQCs showed that an instructor's teaching method had a highly significant effect on student reasoning following course instruction, especially for questions pertaining to cellular-level, carbon-transforming processes. We conclude that using targeted in-class activities had a beneficial effect on student learning regardless of major or class size, and argue that using diagnostic questions to identify effective learning activities is a valuable strategy for promoting learning, as gains from lecture-only classes were minimal. 相似文献

Meta-analyses of active-learning research consistently show that active-learning techniques result in greater student performance than traditional lecture-based courses. However, some individual studies show no effect of active-learning interventions. This may be due to inexperienced implementation of active learning. To minimize the effect of inexperience, we should try to provide more explicit implementation recommendations based on research into the key components of effective active learning. We investigated the optimal implementation of active-learning exercises within a “lecture” course. Two sections of nonmajors biology were taught by the same instructor, in the same semester, using the same instructional materials and assessments. Students in one section completed in-class active-learning exercises in cooperative groups, while students in the other section completed the same activities individually. Performance on low-level, multiple-choice assessments was not significantly different between sections. However, students who worked in cooperative groups on the in-class activities significantly outperformed students who completed the activities individually on the higher-level, extended-response questions. Our results provide additional evidence that group processing of activities should be the recommended mode of implementation for in-class active-learning exercises. 相似文献

The current research examined the effects of a critical thinking (CT) e-learning course taught through argument mapping (AM) on measures of CT ability. Seventy-four undergraduate psychology students were allocated to either an AM-infused CT e-learning course or a no instruction control group and were tested both before and after an 8-week intervention period on CT ability using the Halpern Critical Thinking Assessment. Results revealed that participation in the AM-infused CT course significantly enhanced overall CT ability and all CT sub-scale abilities from pre- to post-testing and that post-test performance was positively correlated with motivation towards learning and dispositional need for cognition. In addition, AM-infused CT course participants exhibited a significantly larger gain in both overall CT and in argument analysis (a CT subscale) than controls. There were no effects of training on either motivation for learning or need for cognition. However, both the latter variables were correlated with CT ability at post-testing. Results are discussed in light of research and theory on the best practices of providing CT instruction through argument mapping and e-learning environments. 相似文献

The purpose of this study was to investigate 8th graders with different learning styles their motivation outcomes after implementing
10 weeks (40 hours) inquiry-based teaching. Two hundreds and fifty four 8th graders were involved in experimental group, this
group of students experienced inquiry instruction. Two hundreds and thirty two 8th graders were involved in control group,
they were taught by traditional science teaching. Students' motivation toward science learning questionnaire (SMTSL) (Tuan,
Chin & Shieh, 2005) were implemented in both groups in the beginning and at the end of the study. Students in the experimental
group filled out learning preference questionnaire (Lumsdaine & Lumsdaine, 1995) in the beginning of the study. Forty students
which represent different learning styles were chosen from five experimental classes to conduct post-test interview. Paired
t-test, MANOVA, analytic inductive methods were used for analyzing both qualitative and quantitative data. Findings indicated
that after inquiry instruction students' motivation increased significantly (p<.001) than students who enrolled in traditional teaching. Four different learning styles of students increased significantly
(p<.005) in SMTSL scales: self-efficacy, active learning strategies, science learning value, performance goal and achievement
goal. No significant difference was found among four learning styles of students' motivation after inquiry teaching. Interview
data supported that most of students with different learning styles were willing to participate in the inquiry learning activities,
while they hold different reasons for their engagement. Findings confirm inquiry-based science teaching can motivate students
with different learning styles in science learning.

ABSTRACTJust-in-time teaching and peer instruction are two student-centred approaches that have been widely employed in various science subjects but seldom in language classrooms. This research proposed a flipped learning model through technology-enhanced just-in-time teaching and peer instruction and investigated the effectiveness of this model in promoting English learning. Two groups of upper intermediate EFL learners participated in the study and learned in two different flipped learning modes, one with the newly proposed approach and the other with the conventional flipped learning approach. The results showed that the proposed model outperformed the conventional model in promoting the development of students’ writing skills, motivation, and tendency of critical thinking. The use of an assessment-centred tool (e.g. EDpuzzle) for interactive videos and cloud-based tools for real-time collaboration (e.g. Padlet and Google Docs) assisted in creating scaffolded learning experience, sharing culture, and opportunities of peer instruction for students in the flipped classroom with Just-in-time teaching and peer instruction. Such results implied that our flipped learning model is very conducive to language learning, and it is advised to be employed more widely in various language learning classes. 相似文献

Given the recent reported common occurrence of mediocre or substandard academic performance by students in colleges and universities, it has become essential to identify pedagogical factors that might lessen or reverse this trend. Kolb’s experiential learning, Pintrich’s student learning motivation, and cognitive load theories were used as a framework to assess active teaching moderation of the effects of course difficulty on course performance and learning motivation. Hierarchical ordinary least squares (OLS) regression was used to analyse the data. Research subjects were recruited from a medium-sized historically Black college and university (HBCU) students enrolled in STEM (science, technology, engineering, and mathematics) and Business (i.e. management, economics, or accounting) classes. Active teaching was a positive predictor of course grade and learning motivation. Course difficulty was a negative predictor of course grade. Interaction analysis revealed that increases in active teaching reduced (i.e. moderated) the negative relationship between course difficulty on both course grade and learning motivation. Overall, the findings suggest that student learning outcomes are certainly a function of pedagogy (e.g. active teaching), psychological/affective (e.g. learning motivation), and learning content complexity. Active teaching environments should (1) address both cognitive load and emotional responses attributed to difficult coursework, and (2) provide efficacy building opportunities during instructional delivery. 相似文献

Materials science, which entails the practices of selecting, testing, and characterizing materials, is an important discipline
within the study of matter. This paper examines how third grade students’ materials science performance changes over the course
of instruction based on an engineering design challenge. We conducted a case study of nine students who participated in engineering
design-based science instruction with the goal of constructing a stable, quiet, thermally comfortable model house. The learning
outcome of materials science practices was assessed by clinical interviews conducted before and after the instruction, and
the learning process was assessed by students’ workbooks completed during the instruction. The interviews included two materials
selection tasks for designing a sturdy stepstool and an insulated pet habitat. Results indicate that: (1) students significantly
improved on both materials selection tasks, (2) their gains were significantly positively associated with the degree of completion
of their workbooks, and (3) students who were highly engaged with the workbook’s reflective record-keeping tasks showed the
greatest improvement on the interviews. These findings suggest the important role workbooks can play in facilitating elementary
students’ learning of science through authentic activity such as engineering design. 相似文献

This qualitative investigation explored the beliefs and practices of one secondary science teacher, Diane, who differentiated instruction and studied how technology facilitated her differentiation. Diane was selected based on the results of a previous study, in which data indicated that Diane understood how to design and implement proactively planned, flexible, engaging instructional activities in response to students’ learning needs better than the other study participants. Data for the present study included 3 h of semi-structured interview responses, 37.5 h of observations of science instruction, and other artifacts such as instructional materials. This variety of data allowed for triangulation of the evidence. Data were analyzed using a constant comparative approach. Results indicated that technology played an integral role in Diane’s planning and implementation of differentiated science lessons. The technology-enhanced differentiated lessons employed by Diane typically attended to students’ different learning profiles or interest through modification of process or product. This study provides practical strategies for science teachers beginning to differentiate instruction, and recommendations for science teacher educators and school and district administrators. Future research should explore student outcomes, supports for effective formative assessment, and technology-enhanced readiness differentiation among secondary science teachers. 相似文献

This paper describes a qualitative study that investigated the nature of the participation structures and how the participation structures were organized by four science teachers when they constructed and communicated science content in their classrooms with computer technology. Participation structures focus on the activity structures and processes in social settings like classrooms thereby providing glimpses into the complex dynamics of teacher–students interactions, configurations, and conventions during collective meaning making and knowledge creation. Data included observations, interviews, and focus group interviews. Analysis revealed that the dominant participation structure evident within participants’ instruction with computer technology was (Teacher) initiation–(Student and Teacher) response sequences–(Teacher) evaluate participation structure. Three key events characterized the how participants organized this participation structure in their classrooms: setting the stage for interactive instruction, the joint activity, and maintaining accountability. Implications include the following: (1) teacher educators need to tap into the knowledge base that underscores science teachers’ learning to teach philosophies when computer technology is used in instruction. (2) Teacher educators need to emphasize the essential idea that learning and cognition is not situated within the computer technology but within the pedagogical practices, specifically the participation structures. (3) The pedagogical practices developed with the integration or with the use of computer technology underscored by the teachers’ own knowledge of classroom contexts and curriculum needs to be the focus for how students learn science content with computer technology instead of just focusing on how computer technology solely supports students learning of science content. 相似文献

This study evaluates a cooperative learning approach for teaching anatomy to health science students incorporating small group and peer instruction based on the jigsaw method first described in the 1970's. Fifty-three volunteers participated in abdominal anatomy workshops. Students were given time to become an “expert” in one of four segments of the topic (sub-topics) by allocating groups to work-stations with learning resources: axial computerized tomography (CT) of abdominal structures, axial CT of abdominal blood vessels, angiograms and venograms of abdominal blood vessels and structures located within abdominal quadrants. In the second part of workshop, students were redistributed into “jigsaw” learning groups with at least one “expert” at each workstation. The “jigsaw” learning groups then circulated between workstations learning all sub-topics with the “expert” teaching others in their group. To assess abdominal anatomy knowledge, students completed a quiz pre- and post- workshop. Students increased their knowledge with significant improvements in quiz scores irrespective of prior exposure to lectures or practical classes related to the workshop topic. The evidence for long-term retention of knowledge, assessed by comparing end-semester examination performance of workshop participants with workshop nonparticipants, was less convincing. Workshop participants rated the jigsaw workshop highly for both educational value and enjoyment and felt the teaching approach would improve their course performance. The jigsaw method improved anatomy knowledge in the short-term by engaging students in group work and peer-led learning, with minimal supervision required. Reported outcomes suggest that cooperative learning approaches can lead to gains in student performance and motivation to learn.

Flipping the classroom and instructional technology integration in a college-level information systems spreadsheet course 总被引：2，自引：0，他引：2

The purpose of this research was to explore how technology can be used to teach technological skills and to determine what benefit flipping the classroom might have for students taking an introductory-level college course on spreadsheets in terms of student achievement and satisfaction with the class. A pretest posttest quasi-experimental mixed methods design was utilized to determine any differences in student achievement that might be associated with the instructional approach being used. In addition, the scalability of each approach was evaluated along with students’ perceptions of these approaches to determine the affect each intervention might have on a student’s motivation to learn. The simulation-based instruction tested in this study was found to be an extremely scalable solution but less effective than the regular classroom and flipped classroom approaches in terms of student learning. While students did demonstrate learning gains, the process focus of the simulation’s instruction and assessments frustrated students and decreased their motivation to learn. Students’ attitudes towards the topic, their willingness to refer the course to others, and the likelihood that they would take another course like this were considerably lower than those of students in the flipped or regular classroom situations. The results of this study support the conclusion that a technology enhanced flipped classroom was both effective and scalable; it better facilitated learning than the simulation-based training and students found this approach to be more motivating in that it allowed for greater differentiation of instruction. 相似文献
