Science laboratory learning has been lauded for decades for its role in fostering positive student attitudes about science and developing students’ interest in science and ability to use equipment. An expanding body of research has demonstrated the significant influence of laboratory environment on student learning. Further research has demonstrated differences in student perceptions based on giftedness. To explore the relationship between giftedness and students’ perceptions of their learning environment, we examined students’ perceptions of their laboratory learning environment in biology courses, including courses designated for high-achieving versus regular-achieving students. In addition, to explore the relationship between students’ perceptions and the extent of their experience with laboratory learning in a particular discipline, we examined students’ perceptions of their laboratory learning environment in first-year biology courses versus elective biology courses that require first-year biology as a prerequisite. We found that students in high-achieving courses had a more favourable perception of all aspects of their learning environment when compared with students in regular courses. In addition, student perceptions of their laboratory appeared to be influenced by the extent of their experience in learning science. Perceptions were consistent amongst regular- and high-achieving students regardless of grade level. In addition, perceptions of students in first year and beyond were consistent regardless of grade level. These findings have critical applications in curriculum development as well as in the classroom. Teachers can use student perceptions of their learning environment to emphasize critical pedagogical approaches and modify other areas that enable enhancement of the science laboratory learning environment.  相似文献

This article describes the development of an interactive computer‐based laboratory manual, created to facilitate the teaching and learning of medical histology. The overarching goal of developing the manual is to facilitate self‐directed group interactivities that actively engage students during laboratory sessions. The design of the manual includes guided instruction for students to navigate virtual slides, exercises for students to monitor learning, and cases to provide clinical relevance. At the end of the laboratory activities, student groups can generate a laboratory report that may be used to provide formative feedback. The instructional value of the manual was evaluated by a questionnaire containing both closed‐ended and open‐ended items. Closed‐ended items using a five‐point Likert‐scale assessed the format and navigation, instructional contents, group process, and learning process. Open‐ended items assessed student's perception on the effectiveness of the manual in facilitating their learning. After implementation for two consecutive years, student evaluation of the manual was highly positive and indicated that it facilitated their learning by reinforcing and clarifying classroom sessions, improved their understanding, facilitated active and cooperative learning, and supported self‐monitoring of their learning.

Laboratory classes are commonplace and essential in biology departments but can sometimes be cumbersome, unreliable, and a drain on time and resources. As university intakes increase, pressure on budgets and staff time can often lead to reduction in practical class provision. Frequently, the ability to use laboratory equipment, mix solutions, and manipulate test animals are essential learning outcomes, and “wet” laboratory classes are thus appropriate. In others, however, interpretation and manipulation of the data are the primary learning outcomes, and here, computer-based simulations can provide a cheaper, easier, and less time- and labor-intensive alternative. We report the evaluation of two computer-based simulations of practical exercises: the first in chromosome analysis, the second in bioinformatics. Simulations can provide significant time savings to students (by a factor of four in our first case study) without affecting learning, as measured by performance in assessment. Moreover, under certain circumstances, performance can be improved by the use of simulations (by 7% in our second case study). We concluded that the introduction of these simulations can significantly enhance student learning where consideration of the learning outcomes indicates that it might be appropriate. In addition, they can offer significant benefits to teaching staff.  相似文献

This study explored a new strategy of assessing laboratory skills in a molecular biology course to improve: student effort in preparation for and participation in laboratory work; valid evaluation of learning outcomes; and students’ employment prospects through provision of evidence of their skills. Previously, assessment was based on written laboratory reports and examinations, not on the demonstration of practical skills per se. This action research project involved altering the assessment design so that a greater proportion of the marks was allocated to active participation and learning in the laboratory, partially replacing a single examination with direct observation of student participation and learning over a prolonged period of weekly laboratory sessions. We ascertained staff and students’ perceptions of the new assessment processes by means of a Likert scale questionnaire, student focus group and individual staff interviews. Overall, students and staff evaluated the new assessment structure positively, citing fairness, authenticity and reward for effort. Results also revealed the need for specific training of staff in this form of assessment and indicated staff–student ratios made assessment burdensome. Four out of five students reported that an increased awareness of the importance of practical laboratory skills stimulated them to greater efforts to achieve.  相似文献

Retrieval practice has been shown to produce powerful learning gains in laboratory experiments but has seldom been explored in classrooms as a means of enhancing students’ learning of their course-relevant material. Furthermore, research is lacking concerning the role of individual differences in learning from retrieval. The current study explored the effects of retrieval in a large undergraduate introductory biology course as a function of individual differences in student achievement. Students completed in-class exercises that required them to retrieve course information (e.g., recalling definitions for terms and labeling diagrams) followed by feedback or to simply copy the information without retrieving it. A later quiz over the information showed that high-performing students benefited more from retrieving than copying, whereas middle- and low-performing students benefited more from copying than retrieving. When asked to predict their quiz scores following the in-class exercises, high-performers demonstrated better overall metacognitive calibration compared to middle- or low-performers. These results highlight the importance of individual differences in learning from retrieval and encourage future research using course-relevant material to consider the role of student achievement in classroom-based interventions.  相似文献

Dental students in third (n?=?35) and fifth years (n?=?50) at Adelaide and Trinity College Dental Schools were surveyed about their experiences of assessment and their perceptions of the importance of particular aspects of assessment. Students reported on their assessment experience within their programmes by describing a critical assessment incident and their response to it, and also rated assessment purposes and features using a 5‐point Likert scale of relative importance. The students described a range of assessment methods, including group assignments, vivas, laboratory assessment, and problem‐based learning tutorials, but written examinations/tests and clinical assessment were discussed most frequently. Negative assessment experiences were commonly noted. The two most frequently raised issues were lack of congruence between student and staff perceptions of performance, and not receiving adequate feedback. There were no significant differences between years or schools in students’ ratings of the importance of assessment purposes. Overall, the students rated the provision of feedback on learning and motivation for learning as the most important purposes (>?80%). Patient‐based scenarios were rated as the most important method for judging students’ learning (>?90%), whilst group‐work tasks were rated of little importance. Overall, students rated clear requirements and feedback as the most important characteristics for positive assessment outcomes. Students’ ratings of assessment purposes, characteristics and methods closely matched the features of good assessment practice found in the literature. However, their assessment experiences indicate the need for review of assessment in both schools, particularly related to student–staff expectations of performance levels, and the provision of feedback.  相似文献

Graduate employment rates and self-reported employability are increasingly a feature of higher education funding measures. However, graduate outcomes do not denote the whole learning experience of the student nor is the student experience reducible to a single statistic. This paper discusses a design-centric approach to employability development which was enacted within a hybrid learning space. The study engaged 52 final-year speech pathology students, their lecturer, the lead researcher and a career practitioner (advisor) at an Australian university. Students first created personalized employability profiles using an established online self-reflection tool. The online tool produced a personalized report and enabled students to access developmental resources relating to employability and student success. The project team used anonymized student data to transform a previously generic “careers” workshop into a targeted workshop in which students explored individual and cohort findings and participated in developmental activities informed by the data. The initiative’s contribution to learning space research is in its composition as a hybrid learning space in which educators and students engaged as learners and developers of their online learning spaces, and educators collaborated to analyze student data and inform learning and teaching enhancements within the same study period. It is anticipated that the data from subsequent years will inform the curricular review, particularly if subsequent student cohorts express similar concerns. Implications for higher education policy and practice are discussed.  相似文献

We implemented a "how to study" workshop for small groups of students (6-12) for N = 93 consenting students, randomly assigned from a large introductory biology class. The goal of this workshop was to teach students self-regulating techniques with visualization-based exercises as a foundation for learning and critical thinking in two areas: information processing and self-testing. During the workshop, students worked individually or in groups and received immediate feedback on their progress. Here, we describe two individual workshop exercises, report their immediate results, describe students' reactions (based on the workshop instructors' experience and student feedback), and report student performance on workshop-related questions on the final exam. Students rated the workshop activities highly and performed significantly better on workshop-related final exam questions than the control groups. This was the case for both lower- and higher-order thinking questions. Student achievement (i.e., grade point average) was significantly correlated with overall final exam performance but not with workshop outcomes. This long-term (10 wk) retention of a self-testing effect across question levels and student achievement is a promising endorsement for future large-scale implementation and further evaluation of this "how to study" workshop as a study support for introductory biology (and other science) students.  相似文献

Laboratory science classes offered to students learning at a distance require a methodology that allows for the completion of tactile activities. Literature describes three different methods of solving the distance laboratory dilemma: kit-based laboratory experience, computer-based laboratory experience, and campus-based laboratory experience, which all allow the implementation of laboratory activities to students learning science at a distance. This article describes an additional method of implementing laboratory activities using interactive television. Interactive television allows real-time, synchronous student–instructor communication and interaction.  相似文献

Homework gives students an opportunity to practice important college‐level physics skills. A switch to Web‐based homework alters the nature of feedback received, potentially changing the pedagogical benefit. Calculus‐ and algebra‐based introductory physics students enrolled in large paired lecture sections at a public university completed homework of standard end‐of‐the‐chapter exercises using either the Web or paper. Comparison of their performances on regular exams, conceptual exams, quizzes, laboratory, and homework showed no significant differences between groups; other measures were found to be strong predictors of performance. This indicates that the change in medium itself has limited effect on student learning. Ways in which Web‐based homework could enable exercises with greater pedagogical value are discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 1050–1071, 2003  相似文献

There are arguably many factors that affect the way a student learns. A recent report by the Higher Education Policy Institute (HEPI) and the Higher Education Academy (HEA) on student academic experience in the UK states that class size is an important factor in the quality of the student experience and that smaller class sizes provide greater educational benefit than the delivery of lectures. This article assesses research related to lectures, lecture attendance of medical students and their learning approaches in higher education outside the clinical setting. A questionnaire and focus groups were employed to gather quantitative and qualitative data. The results show that students value lectures in the curriculum alongside other teaching and learning methods.  相似文献

Polymerase chain reaction (PCR) and gel electrophoresis have become common techniques used in undergraduate molecular and cell biology labs. Although students enjoy learning these techniques, they often cannot fully comprehend and analyze the outcomes of their experiments because of a disconnect between concepts taught in lecture and experiments done in lab. Here we report the development and implementation of novel exercises that integrate the biological concepts of DNA structure and replication with the techniques of PCR and gel electrophoresis. Learning goals were defined based on concepts taught throughout the cell biology lab course and learning objectives specific to the PCR and gel electrophoresis lab. Exercises developed to promote critical thinking and target the underlying concepts of PCR, primer design, gel analysis, and troubleshooting were incorporated into an existing lab unit based on the detection of genetically modified organisms. Evaluative assessments for each exercise were aligned with the learning goals and used to measure student learning achievements. Our analysis found that the exercises were effective in enhancing student understanding of these concepts as shown by student performance across all learning goals. The new materials were particularly helpful in acquiring relevant knowledge, fostering critical-thinking skills, and uncovering prevalent misconceptions.  相似文献

Over the past decade, more and more business schools are attempting to teach business processes (BPs) by using enterprise resource planning (ERP) software in their curricula. Currently, most studies involving ERP software in the academy have concentrated on learning and teaching via self‐assessment surveys or curriculum integration. This research extended previous studies by attempting to measure student knowledge acquisition of BP concepts (BPC) about two common BP cycles through hands‐on exercises using ERP software. Assessments of students’ knowledge about BP were conducted at multiple time points during the study. In addition, a Technology Acceptance Model (TAM)‐based survey was employed to analyze student self‐assessment about improved understanding of BPs though ERP hands‐on exercises. Results from our empirical study indicated that there is no clear evidence that students’ knowledge about BPs significantly improved after experiencing ERP software. However, students’ self‐assessment showed that there is a positive relationship between their comprehension of BPs and hands‐on experience with ERP software. Our research findings concurred with previous research, and studies undertaken in other disciplines.  相似文献

Abstract

In the neo-liberal context of a UK university, responding to student feedback in order to raise student satisfaction levels is important in improving National Student Survey (NSS) scores. This article focuses on the impact of a UK university’s new student feedback questionnaire - for individual modules - which used the NSS questions. The research draws on survey data (N?=?101) to identify lecturers’ views and three student focus groups. The outcomes raised issues relating to performativity, professionalism and ‘provision’, the latter defined as the university’s contract with each student, including the aspects that affect the student learning experience but are beyond the lecturers’ control, for example, class sizes and timetables. The results indicate that by recognising the impact of provision university managers may be better able to develop systemic improvements to student experience and (in the UK) a corresponding uplift in NSS and Teaching Excellence Framework (TEF) results. The article puts forward a model linking performativity, professionalism and provision to the relationships between university managers, academics and students. This model could enrich understandings of professionalism and performativity, extend the range of issues affecting student experience in SETs and support data analysis in future research studies.  相似文献

In recent years, simulation has increasingly underpinned the acquisition of pre-clinical skills by undergraduate medical imaging (diagnostic radiography) students. This project aimed to evaluate the impact of an innovative virtual reality (VR) learning environment on the development of technical proficiency by students. The study assessed the technical skills of first year medical imaging students. The learning experience by each student was either via traditional laboratory-based simulation or VR simulation, for two specified anatomical protocols. Following the learning experience, the students performed role-plays and were assessed on their technical proficiency. The type of learning environment, laboratory-based or VR simulation, was recorded for each radiographic procedure, as well as demographic data. Data demonstrated an improved total role-play skill score for those students trained using VR software simulation compared with the total role-play skills score traditional laboratory simulation. Demographic multivariable analysis demonstrated no statistically significant association of age, gender, gaming skills/activity with the outcome. The novel medical imaging VR simulation learning tool facilitated technical skill acquisition, equal to, or slightly better than traditional laboratory training. Ongoing data collection will evaluate the impact this VR software has on the undergraduate medical imaging student.

Several programs in health professional education require or are considering requiring upper-level human anatomy as prerequisite for their applicants. Undergraduate students are confronted with few institutions offering such a course, in part because of the expense and logistical issues associated with a cadaver-based human anatomy course. This study describes the development of and student reactions to an upper-level human anatomy laboratory course for undergraduate students that used a regional approach and contemporary, alternative teaching methods to a cadaver-based course. The alternative pedagogy to deliver the curriculum included use of commercially available, three-dimensional anatomical virtual dissection software, anatomical models coupled with a learning management system to offer Web-based learning, and a new laboratory manual with collaborative exercises designed to develop the student's anatomical skills and collaborative team skills. A Likert-scale survey with open-ended questions was used to ascertain student perceptions of the course and its various aspects. Students perceived that the noncadaver-based, upper-level human anatomy course with an engaging, regional approach is highly valuable in their learning of anatomy. anatomy.  相似文献

Assessment for learning approaches, such as peer review exercises may improve student performance in summative assessments and increase their satisfaction with assessment practices. We conducted a mixed methods study to evaluate the effectiveness of an oral peer review exercise among post-graduate students. We examined: (1) final assessment grades among students who did and did not take part in the peer review exercise; (2) student perceptions of the impact of the peer review exercise; and (3) student understanding of, and satisfaction with, this new assessment practice. We found that students who took part in the exercise had a significantly higher mean grade in a subsequent summative oral presentation assessment than students who did not take part in the exercise. Students gained a better understanding of assessment and marking criteria and expressed increased confidence and decreased anxiety about completing the subsequent summative assessment. Assessment for learning improves academic attainment and the learning experience in postgraduate students.  相似文献

A small-scale concept-based laboratory component: the best of both worlds   总被引:2,自引:2,他引:0  
In this article, we describe an exploratory study of a small-scale, concept-driven, voluntary laboratory component of Introductory Biology at the Massachusetts Institute of Technology. We wished to investigate whether students' attitudes toward biology and their understanding of basic biological principles would improve through concept-based learning in a laboratory environment. With these goals in mind, and using our Biology Concept Framework as a guide, we designed laboratory exercises to connect topics from the lecture portion of the course and highlight key concepts. We also strove to make abstract concepts tangible, encourage learning in nonlecture format, expose the students to scientific method in action, and convey the excitement of performing experiments. Our initial small-scale assessments indicate participation in the laboratory component, which featured both hands-on and minds-on components, improved student learning and retention of basic biological concepts. Further investigation will focus on improving the balance between the minds-on concept-based learning and the hands-on experimental component of the laboratory.  相似文献

Real-time kinematical analysis of physical phenomenon is the graphing of displacement, velocity, and acceleration versus time data simultaneously with the motion of the object. Brasell (1987) found that students using real-time analysis with microcomputer-based laboratory tools significantly improved their kinematics graphing skills as compared to students using delayed-time graphing (kinematics graphs produced after the motion of the object). However, using computer reanimation of videotaped images, Beichner (1990) found no difference in student learning between the simultaneous-time (kinematics graphs produced simultaneously with the motion of the image of the object, such as a video-recorded image or a computer reanimated image) and the delayed-time treatments. This investigation considers student analysis of videodisc-recorded images, with treatments over an extended time. Using quantitative, qualitative, and retention data, we found no significant learning difference between using simultaneous-time and delayed-time analysis for student understanding of kinematics graphs. However, the results imply that simultaneous-time analysis may have advantages in some areas.  相似文献
