An increase in online education is causing science educators to evaluate student cognitive understanding after completing virtual, computer-simulated laboratories. Online education has demonstrated comparable learning gains when analysed to those of the traditional classroom, but research is mixed when reviewing students’ ability to manipulate tangible laboratory equipment after participating in online experimentation. The question remains, are students who are exclusively enrolled in online science courses equipped with the cognitive ability to operate laboratory equipment within a physical laboratory? When considering the optimal learning environment for science majors, educators have discovered the blended classroom may provide the perfect opportunity to combine the benefits of face-to-face instruction and feedback with the reinforcement of scientific theory through technology integration. New advances in virtual education provide promising examples of enhancing the online classroom laboratory in all scientific disciplines. Further insight into the blended classroom has the potential to influence the field of education towards an optimal learning environment for science majors in colleges and universities. 相似文献

Active learning has attracted considerable attention in higher education in response to concerns about how and what students are learning. There are many different forms of active learning, yet most of them are classroom based. We propose an alternative to active learning in the classroom through active learning outside of the classroom in the form of student consulting projects. While the literature on student consulting has largely focused on projects to assist small business owners, this research demonstrates the potential for using student-consulting projects in the Production/Operations Management course. We use a case study to describe the use of a student-consulting project as an alternative to the other types of active learning described in the Operations Management education literature. 相似文献

ABSTRACT: Critical thinking skills (CTS) are the core learning outcome measures for higher education. Generally, CTS are not extensively developed or practiced during primary and secondary education. As such, early cultivation of CTS is essential for mastery prior to collegiate matriculation. Weekly engagement in 50 min of classroom discussion with student feedback (CDSF) was utilized to develop the CTS of students in an introductory food science course at Purdue Univ. Students' critical thinking ability was assessed longitudinally over a 16‐wk semester using the ACT‐CAAP? (Collegiate Assessment of Academic Proficiency) critical thinking test. The ACT‐CAAP measures the students' ability to analyze, evaluate, and extend an argument described in a short passage. We hypothesized that the implementation of CDSF for 16 wk would expedite development of CTS for students enrolled in the course. The CDSF intervention significantly increased critical thinking ability for non‐native English speaking students as compared to native English speaking students. Students who were classified as sophomore status or above when compared to freshmen and students enrolled as food science majors when compared to other majors also demonstrated increased critical thinking ability. Recitation size also significantly influenced critical thinking ability where students enrolled in a relatively small recitation section had elevated critical thinking when compared to the abilities of those students enrolled in a large recitation. These observations suggest that engaging students in classroom discussions with student‐led feedback is a useful instructional technique for developing CTS. Further, the data suggest the development of critical thinking skill among food science majors can be augmented when classroom discussions with student‐led feedback are conducted in smaller sized recitations. 相似文献

A small group of Russian teachers who were interested in adopting aspects of the US science educational reform movement, participated in a constructivist science teaching project. Baseline data from translated classroom observations were scored using the science classroom observation rubric from the expert science teaching educational evaluation model (ESTEEM) and compared with a traditional (teacher centered) group of US science teachers and a group of US constructivist (student centered) science teachers. The purpose of the research is to investigate how Russian teachers who were beginning a US science education reform project compared with two US groups of science teachers, a traditional and a reform group. Analysis of variance was used to analyse the total rubric score and four categories for the Russian/traditional US and the Russian/constructivist US studies in order to examine closely the traditional and the constructivist teaching practises. In the first study US traditional teachers were statistically higher on 'facilitating the learning process' and 'context-specific pedagogy'. Russian teachers were higher on the 'content' category. In the second study the experienced constructivist US teachers were statistically higher on all four categories and the total rubric score. The educational culture of both countries is very traditional. However, the reform movement in science education has changed some US teachers, and is in the process of changing some Russian teachers. Both countries are working on the reform process. The results of this study provide baseline information on a small group of Russian teachers, who have chosen to be a part of the ideas contained in the US science education reform movement. The study also promotes the mutual understanding of both cultures among teachers, administrators, and researchers, which should ultimately form a bond for working together on common educational issues. 相似文献

Phenomena-based approaches have become popular for elementary school teachers to engage children's innate curiosity in the natural world. However, integrating such phenomena-based approaches in existing science courses within teacher education programs present potential challenges for both preservice elementary teachers (PSETs) and for laboratory instructors, both of whom may have had limited opportunities to learn or teach science within the student and instructor roles inherent within these approaches. This study uses a convergent parallel mixed-methods approach to investigate PSETs' perceptions of their laboratory instructor's role within a Physical Science phenomena-based laboratory curriculum and how it impacts their conceptual development (2 instructors/121 students). We also examine how the two laboratory instructors' discursive moves within the laboratory align with their's and PSETs' perceptions of the instructor role. Qualitative data includes triangulation between a student questionnaire, an instructor questionnaire, and video classroom observations, while quantitative data includes a nine-item open response pre-/post-semester conceptual test. Guided by Mortimer's and Scott's analytic framework, our findings show that students primarily perceive their instructors as a guide/facilitator or an authoritarian/evaluator. Using Linn's knowledge integration framework, analysis of pre-/post-tests indicates that student outcomes align with students' perceptions of their instructors, with students who perceive their instructor as a guide/facilitator having significantly better pre-/post-outcomes. Additional analysis of scientific discourse from the classroom observations illustrates how one instructor primarily supports PSETs' perspectives on authentic science learning through dialogic–interactive talk moves whereas the other instructor epistemologically stifles personally relevant investigations with authoritative–interactive or authoritative–noninteractive discourse moves. Overall, this study concludes by discussing challenges facing laboratory instructors that need careful consideration for phenomena-based approaches. 相似文献

In Portugal, the number of students in higher education increased from 80,000 in 1975 to 381,000 in 2000 (a change from 11% to 53% in the age group 18–22), meaning a major change in the diversity of student population with consequences well known and studied in other countries. The teaching of chemistry at the University of Aveiro, for the first‐year students of science and engineering, has been subjected to continuous attention to implement quality and student‐centred approaches. The work devoted to excellence and deep learning by several authors has been carefully followed and considered. This communication reports research work on chemistry teaching, associated with those developments for first‐year students. The work included the design of strategies and the adoption of teaching and learning activities exploring ways to stimulate active learning by improving the quality of classroom interactions. In addition to regular lectures, large classes' teaching based on student‐generated questions was explored. In order to improve students' motivation and stimulate their curiosity, conference‐lectures were adopted to deal with selected topics of wide scientific, technological and social interest. Quantitative analysis and discussion of selected case studies, together with the organization of laboratory classes based on selected enquiry‐based experiments, planned and executed by students, stimulated deep learning processes. A sample of 32 students was followed in the academic year of 2000/01 and the results obtained are here discussed in comparison with those of a sample of 100 students followed in 2001/02. Particular attention was paid to the quality of classroom interactions, the use of questions by students and their views about the course design. 相似文献

The purpose of this study was to describe the influence of constructivist classroom contextual factors in a life science laboratory
and a traditional science classroom on elementary students’ motivation and learning strategy use. The Constructivist Teaching
Inventory was used to examine classroom contextual factors. The Motivated Strategies for Learning Questionnaire was used to
examine student motivation and learning strategies. A Wilcoxon nonparametric test determined that constructivist teaching
practices were found to occur more often in the life laboratory than in the regular classroom. Although constructivist teaching
practices increased at each observation time in both the regular classroom and in the life laboratory, a Friedman test determined
that they were not statistically significant increases. Paired sample t tests determined that student motivation and learning
strategies were higher in the life laboratory than in the regular classroom overall as well as at each survey time except
for learning strategies at Post 1. A 2 × 4 between 3 within repeated measure ANOVA determined that student MSLQ motivation
and learning strategy scores in the regular classroom varied statistically significantly by teacher. Student MSLQ motivation
and learning strategy scores in the life laboratory varied statistically significantly by teacher. To triangulate data, individual
interviews of students were conducted at the end of the semester and revealed students regard the life laboratory as an asset
to their science study; however, students do appreciate and value working in the learning environment that the regular classroom
provides. 相似文献

Abstract This study compared the student course evaluations of standard education and distance learning courses in the school of social work of one southern university. The sample included 14 distance learning (DL) and 122 standard education courses. A 20-item quantitative student course evaluation and a 7-item qualitative questionnaire were used to compare differences between social work courses taught in a standard classroom setting with those taught using distance learning technology. Comparisons of identical courses taught in both formats found that students rated distance learning higher than the standard classroom for a course having predominantly lecture content. Conversely, ratings for clinical practice courses were just the opposite with lower ratings for distance learning than the standard classroom. Results of a qualitative survey (n = 39) of students conducted at the end of a course taught by distance learning found that 73% of the students felt that distance learning technology interfered with class participation. However, 73% of the students felt the instructor handled technological problems in a professional and patient manner. Although 54% of the students reported that they would take another course by distance learning, more research is needed to determine what social work courses can be most effectively taught by distance and classroom formats. 相似文献

Biology of the twenty-first century is an increasingly quantitative science. Undergraduate biology education therefore needs to provide opportunities for students to develop fluency in the tools and language of quantitative disciplines. Quantitative literacy (QL) is important for future scientists as well as for citizens, who need to interpret numeric information and data-based claims regarding nearly every aspect of daily life. To address the need for QL in biology education, we incorporated quantitative concepts throughout a semester-long introductory biology course at a large research university. Early in the course, we assessed the quantitative skills that students bring to the introductory biology classroom and found that students had difficulties in performing simple calculations, representing data graphically, and articulating data-driven arguments. In response to students'' learning needs, we infused the course with quantitative concepts aligned with the existing course content and learning objectives. The effectiveness of this approach is demonstrated by significant improvement in the quality of students'' graphical representations of biological data. Infusing QL in introductory biology presents challenges. Our study, however, supports the conclusion that it is feasible in the context of an existing course, consistent with the goals of college biology education, and promotes students'' development of important quantitative skills. 相似文献

This paper deals with a required methods course, based on the national curriculum of science and technology for junior high schools. The course participants are pre-service teachers who study towards a B.Sc. degree in education in science and technology parallel to their studies in one of the faculties of sciences or engineering. Working in small teams, the students carry out a project in a Project-Based Learning (PBL) environment. The final outcomes of the project are group and individual written reports, a portfolio, a multimedia presentation and a physical model. The research question was: what implementation issues and processes do higher education students encounter in a Project-Based Learning environment which involves an alternative assessment approach? Qualitative and quantitative tools for collecting data included ‘the participant as observer’ observations at the classroom, semi-structured interviews with students, questionnaire, and analysis of students' reports and products. The findings relate to the advantages of PBL from the students' point of view, the challenges students experienced and perceived while conducting their projects, and the benefits students may gain from formative assessment. 相似文献

The challenge of preparing novice primary teachers for teaching in an educational environment, where science education has
low status and many teachers have limited science content knowledge and lack the confidence to teach science, is great. This
paper reports on an innovation involving a sustained simulation in an undergraduate science education course as a mediational
tool to connect two communities of practice—initial teacher education and expert primary science teaching. The course lecturer
and student teachers role-played the expert classroom teacher and primary students (Years 7/8) respectively in an attempt
to gain insights into teaching and learning through authentic activity that models good practice in primary science teaching
and learning. Activity theory was used to help frame and analyse the data. Findings from the first trial indicate that the
simulation was very effective in initiating science pedagogical content knowledge (PCK) development of primary student teachers. 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 article addresses the impact of race and ethnicity on students' science learning in US schools. Specifically, it discusses (a) the constructs of race, ethnicity, and culture, and the racial and ethnic student composition in US public schools; (b) effective classroom practices for curriculum, instruction, and assessment related to race and ethnicity; and (c) future policy and practice regarding race and ethnicity in science education. We discuss the science learning and teaching of African American, Latino, and Asian American students. Even though Asian American students are viewed as the model minority, some struggle with science learning, because their languages and cultures are seen as hurdles. As there is little defendable science education research related to Native Americans at the precollege level, we remain silent in this area. 相似文献

This investigation examined 10th‐grade biology students' decisions to enroll in elective science courses, and explored certain attitudinal perceptions of students that may be related to such decisions. The student science perceptions were focused on student and classroom attitudes in the context of differing learning cycle classrooms (high paradigmatic/high inquiry, and low paradigmatic/low inquiry). The study also examined possible differences in enrollment decisions/intentions and attitudinal perceptions among males and females in these course contexts. The specific purposes were to: (a) explore possible differences in students' decisions, and in male and female students' decisions to enroll in elective science courses in high versus low paradigmatic learning cycle classrooms; (b) describe patterns and examine possible differences in male and female students' attitudinal perceptions of science in the two course contexts; (c) investigate possible differences in students' science perceptions according to their decisions to enroll in elective science courses, participation in high versus low paradigmatic learning cycle classrooms, and the interaction between these two variables; and (d) examine students' explanations of their decisions to enroll or not enroll in elective science courses. Questionnaire and observation data were collected from 119 students in the classrooms of six learning cycle biology teachers. Results indicated that in classrooms where teachers most closely adhered to the ideal learning cycle, students had more positive attitudes than those in classrooms where teachers deviated from the ideal model. Significantly more females in high paradigmatic learning cycle classrooms planned to continue taking science course work compared with females in low paradigmatic learning cycle classrooms. Male students in low paradigmatic learning cycle classrooms had more negative perceptions of science compared with males in high paradigmatic classrooms, and in some cases, with all female students. It appears that using the model as it was originally designed may lead to more positive attitudes and persistence in science among students. Implications include the need for science educators to help teachers gain more thorough understanding of the learning cycle and its theoretical underpinnings so they may better implement this procedure in classroom teaching. © 2001 John Wiley & Sons, Inc.

Student engagement with science is a long-standing, central interest within science education research. In this article, we examine student engagement with science using a Bourdiusian lens, placing a particular emphasis on the notion of field. Over the course of one academic year, we collected data in an inner London secondary science classroom through lesson observations, interviews and discussion groups with students, and interviews with the teacher. We argue that applying Bourdieusian theory can help better understand differential patterns of student engagement by directing attention to the alignment between students’ habitus and capital, and the field. Student behaviours that did not meet the requirements of the wider field were not recognised and valued as constituting engagement. Even when the ‘rules of the game’ of the science classroom were understood by the students, the tensions they experienced within the field made engaging with science impossible and undesirable. We discuss how a greater focus on the field can be useful for planning future interventions aimed at making science education more equitable. 相似文献

Research apprenticeships for secondary students provide authentic contexts for learning science in which students engage in
scientific investigations with practicing scientists in working laboratory groups. Student experiences in these research apprenticeships
vary depending on the individual nature of the laboratory in which students have been placed. This study explores potential
relationships among student experiences in apprenticeship contexts and desired student outcomes (e.g. science content knowledge,
understandings of nature of science, and aspirations for science oriented career plans). The following two research questions
guided the study: How do participant experiences in and outcomes resulting from an authentic research program for high school
students vary? How does variation in participant experiences in an authentic research program relate to participant outcomes?
Primary data sources were student and mentor interviews in addition to student generated concept maps. Results indicated that
the greatest variance in student experiences existed in the categories of collaboration, epistemic involvement, and understandings
of the significance of research results. The greatest variation in desired student outcomes was observed in student understandings
of nature of science and in students’ future science plans. Results suggested that collaboration and interest in the project
were experience aspects most likely to be related to desired outcomes. Implications for the design of research apprenticeships
for secondary students are discussed. 相似文献
