In the anatomical sciences, e‐learning tools have become a critical component of teaching anatomy when physical space and cadaveric resources are limited. However, studies that use empirical evidence to compare their efficacy to visual‐kinesthetic learning modalities are scarce. The study examined how a visual‐kinesthetic experience, involving a physical skeleton, impacts learning when compared with virtual manipulation of a simple two‐dimensional (2D) e‐learning tool, A.D.A.M. Interactive Anatomy. Students from The University of Western Ontario, Canada (n = 77) participated in a dual‐task study to: (1) investigate if a dual‐task paradigm is an effective tool for measuring cognitive load across these different learning modalities; and (2) to assess the impact of knowledge recall and spatial ability when using them. Students were assessed using knowledge scores, Stroop task reaction times, and mental rotation test scores. Results demonstrated that the dual‐task paradigm was not an effective tool for measuring cognitive load across different learning modalities with respect to kinesthetic learning. However, our study highlighted that handing physical specimens yielded major, positive impacts on performance that a simple commercial e‐learning tool failed to deliver (P < 0.001). Furthermore, students with low spatial ability were significantly disadvantaged when they studied the bony joint and were tested on contralateral images (P = 0.046, R = 0.326). This suggests that, despite limbs being mirror images, students should be taught the anatomy of, as well as procedures on, both sides of the human body, enhancing the ability of all students, regardless of spatial ability, to take anatomical knowledge into the clinic and perform successfully.

The study compared the effects of dynamic geometry software and physical manipulatives on the spatial visualisation skills of first‐year pre‐service mathematics teachers. A pre‐ and post‐test quasi‐experimental design was used. The Purdue Spatial Visualisation Test (PSVT) was used for the pre‐ and post‐test. There were three treatment groups. The first group (n = 34) used Dynamic Geometry Software (DGS) Cabri 3D as a virtual manipulative and the second group (n = 32) used physical manipulatives. In the control group (n = 30), the students received traditional instruction. The results of the study showed that physical manipulatives and DGS‐based types of instruction are more effective in developing the students' spatial visualisation skills than traditional instruction. In addition, students in the DGS‐based group performed better than the physical manipulative‐based group in the views section of the PSVT.  相似文献

The use of mixed reality in science education has been increasing and as such it has become more important to understand how information is learned in these virtual environments. Spatial ability is important in many learning contexts, but especially in neuroanatomy education where learning the locations and spatial relationships between brain regions is paramount. It is currently unclear what role spatial ability plays in mixed reality learning environments, and whether it is different compared to traditional physical environments. To test this, a learning experiment was conducted where students learned neuroanatomy using both mixed reality and a physical plastic model of a brain (N = 27). Spatial ability was assessed and analyzed to determine its effect on performance across the two learning modalities. The results showed that spatial ability facilitated learning in mixed reality (β = 0.21, P = 0.003), but not when using a plastic model (β = 0.08, P = 0.318). A non-significant difference was observed between the modalities in terms of knowledge test performance (d = 0.39, P = 0.052); however, mixed reality was more engaging (d = 0.59, P = 0.005) and learners were more confident in the information they learned compared to using a physical model (d = 0.56, P = 0.007). Overall, these findings suggest that spatial ability is more relevant in virtual learning environments, where the ability to manipulate and interact with an object is diminished or abstracted through a virtual user interface.  相似文献

Despite advances to move anatomy education away from its didactic history, there is a continued need for students to contextualize their studies to make learning more meaningful. This article investigates authentic learning in the context of an inquiry‐based approach to learning human gross anatomy. Utilizing a case‐study design with three groups of students (n = 18) and their facilitators (n = 3), methods of classroom observations, interviews, and artifact collection were utilized to investigate students' experiences of learning through an inquiry project. Qualitative data analysis through open and selective coding produced common meaningful themes of group and student experiences. Overall results demonstrate how the project served as a unique learning experience where learners engaged in the opportunity to make sense of anatomy in context of their interests and wider interdisciplinary considerations through collaborative, group‐based investigation. Results were further considered in context of theoretical frameworks of inquiry‐based and authentic learning. Results from this study demonstrate how students can engage anatomical understandings to inquire and apply disciplinary considerations to their personal lives and the world around them.

College students (Experiment 1) and non-college adults (Experiment 2) studied a computer-based 31-frame lesson on electronics that offered help-screens containing text (text group) or illustrations (pictorial group), and then took a learning test. Participants also took a battery of 14 cognitive measures related to the verbalizer-visualizer dimension including tests of cognitive style, learning preference, spatial ability, and general achievement. In Experiment 3, college students received either both kinds of help-screens or none. Verbalizers and visualizers did not differ on the learning test, and almost all of the verbalizer-visualizer measures failed to produce significant attribute x treatment interactions (ATIs). There was not strong support for the hypothesis that verbal learners and visual learners should be given different kinds of multimedia instruction.  相似文献

This study aimed at identifying the differences between a flipped classroom and a non-flipped classroom instructional model, based on the Self-Determination Theory (SDT). This study employed a mixed-method research approach, using post-tests, questionnaires and focus group interviews during the data collection process. Sixty-one students were the respondents involved in a non-randomised experiment with a control group design, while 10 representative students participated in a focus-group discussion. The results reported that post-test 1 showed no significant difference between the two groups of flipped and non-flipped classroom instruction (t = 1.68, p = .474), while post-tests 2 and 3 were significantly different (t = 5.54, p = .007 < .05) and (t = 10.17, p = .001 < .05). This finding shows that students in the flipped learning environment were more competent handling online tasks and activities, and were able to control their learning outcomes. The survey results showed that the flip-class setting fostered better peer interaction and autonomous learning skills among the students. The flip-class environment had also a positive influence on students’ intrinsic motivation. The qualitative findings from the students’ interviews revealed that students were motivated by the video-recorded lectures, self-regulated learning environments, engagement in class activities and peer interaction. Conclusions from this study showed that the flip-class setting had successfully established the basic psychological needs of SDT, namely: competency, autonomy and relatedness in a flipped classroom model.  相似文献

This study investigated how professional development featuring evidence‐based customization of technology‐enhanced curriculum projects can improve inquiry science teaching and student knowledge integration in earth science. Participants included three middle school sixth‐grade teachers and their classes of students (N = 787) for three consecutive years. Teachers used evidence from their student work to revise the curriculum projects and rethink their teaching strategies. Data were collected through teacher interviews, written reflections, classroom observations, curriculum artifacts, and student assessments. Results suggest that the detailed information about the learning activities of students provided by the assessments embedded in the online curriculum motivated curricular and pedagogical customizations that resulted in both teacher and student learning. Customizations initiated by teachers included revisions of embedded questions, additions of hands‐on investigations, and modifications of teaching strategies. Student performance improved across the three cohorts of students with each year of instructional customization. Coupling evidence from student work with revisions of curriculum and instruction has promise for strengthening professional development and improving science learning. © 2010 Wiley Periodicals, Inc.

The application of Biggs’ and Collis’ Structure of Observed Learning Outcomes taxonomy in the evaluation of student learning about cell membrane transport via a computer‐based learning environment is described in this study. Pre‐test–post‐test comparisons of student outcome data (n = 80) were made across two groups of randomly assigned students: one that received visual and haptic feedback, and one that relied on visual feedback only as they completed their virtual investigations. The results of the Mann–Whitney U‐test indicated that the group mean difference scores were significantly different statistically (p = .043). Practically speaking, this study provides some early evidence suggesting that the haptic augmentation of computer‐based science instruction may lead to a deeper level of processing. The strengths and weaknesses of this current diagnostic approach and a novel approach based on a non‐verbal model of cognition are discussed in light of their potential contributions to the teaching and learning of science.  相似文献

The study examines the effectiveness of visually enhanced instruction that emphasizes molecular representations. Instructional conditions were specified in terms of the visual elaboration level (static and dynamic) and the presentation mode (whole class and individual). Fifty‐two eighth graders (age range 14–15 years) participated in one of the three instructional conditions (dynamic–individual, dynamic–whole class, and static–whole class) designed to improve molecular understanding on chemical change. The results indicated significantly higher performance for students who used dynamic visuals compared with those who used static visuals. Furthermore, students who used dynamic visuals on an individual basis were more consistent in their use of molecular representations compared with students who received whole‐class instruction with dynamic or static visuals. The results favour the use of dynamic visuals (preferably on an individual basis) over static visuals when presenting molecular representations. The results also imply that the effectiveness of instruction will improve if teachers challenge and question the inconsistencies and contradictions between verbal explanations and corresponding molecular representations  相似文献

Two studies were conducted to investigate the effects of cooperative learning on second‐graders’ motivation and learning from text. In Study 1, students (n = 160) in cooperative learning groups were compared with their counterparts (n = 107) in traditional instruction groups. The results revealed a statistically significant difference between the two groups, with more favourable perceptions of teachers’ instructional practices and better reading comprehension in the instructional intervention groups than in the traditional instruction groups. In Study 2, 51 second‐graders participated in the instructional intervention programme. The results showed that students’ positive cooperative behaviour and attitudes were related to their motivation and reading comprehension. When students perceived that their peers were willing to help each other and were committed to the group, they tended to be more motivated and performed better in reading comprehension.  相似文献

This study explored the role of learner-generated and instructor-provided visuals in learning from scientific text. 134 college students studied a lesson on the human circulatory system and then completed recall and transfer tests. Across two consecutive study periods, students were randomly assigned to either view a provided illustration twice (provided-provided), generate a drawing from the text and then revise their drawing (generated-revised), view a provided illustration and then generate a drawing (provided-generated), or generate a drawing and then view a provided illustration (generated-provided). Results indicated a group by learning outcome interaction: the generated-provided and provided-generated groups performed higher on the transfer test and lower on the recall test compared to the provided-provided group. Furthermore, spatial ability was positively associated with learning outcomes among students who generated drawings but not among students in the provided-provided group. Finally, the relationship between spatial ability and learning outcomes among students who generated drawings was mediated by drawing quality. These findings suggest that provided and generated visuals have unique effects on different learning outcomes, and spatial ability plays an important role in supporting learner-generated visuals.  相似文献

Few studies have examined the impact of mastery learning on mastery goal structures or even on students’ motivation more generally. In this study, we examined one middle school that implemented a schoolwide mastery learning system, conducting interviews with a sample of administrators (n = 3), teachers (n = 4), and students (n = 9) to determine how the system was envisioned by the school leadership, implemented by the teaching staff, and perceived by the students. We used deductive qualitative analysis (DQA) to determine visions, practices, and perceptions aligned with achievement goal theory. Results indicated that evaluation practices have the greatest potential to undermine other positive motivational impacts of mastery learning–based instruction. Implications and transferability for research and practice are discussed.  相似文献

This paper addresses student‐teachers' ability to read nature in a woodland habitat before and after a 10‐week ecology course. Reading nature is our definition of the ability to observe, describe and explain basic ecology in the field. Data consists of field‐based pre‐course and post‐course interviews followed up by metacognitive interviews where students analyse their own learning. A bi‐dimensional coding scheme is adopted to examine the range and development of students' ability to read nature. Students find it important to know the ecology of a few key species and they recognize the importance of having learned the language of ecology — ecologish — helping them to describe and discuss ecology. Students generally recognize the excursions as key learning situations in ecology education but they give different reasons for finding excursions so important. This variation will be elaborated in the paper together with the implications for teaching ecology.  相似文献

The effectiveness of clay modeling to written modules is examined to determine the degree of improvement in learning and retention of anatomical 3D relationships among students with different learning preferences. Thirty‐nine undergraduate students enrolled in a cadaver dissection course completed a pre‐assessment examination and the VARK questionnaire, classifying learning preference as visual, auditory, read/write, or kinesthetic. Students were divided into clay, module, and control groups with preference for learning style distributed among groups. The clay and module groups participated in weekly one‐hour classes using either clay models or answering written questions (modules) about anatomical relationships, respectively. The control group received no intervention. Post‐assessment and retention examinations were administered at the end of the semester, and three months later, respectively. Two variables (Δ1, Δ2) represented examination score differences between pre‐ and post‐assessment and between post‐assessment and retention examinations, respectively. The Δ1 for clay and module groups were each significantly higher than controls (21.46 ± 8.2 vs. 15.70 ± 7.5, P ≤ 0.05; and 21.31 ± 6.9 vs. 15.70 ± 7.5, P ≤0.05, respectively). The Δ2 for clay and module groups approached but did not achieve significance over controls (?6.09 ± 5.07 vs. ?8.80 ± 4.60, P = 0.16 and ?5.73 ± 4.47 vs. ?8.80 ± 4.60, P = 0.12, respectively). No significant differences were seen between interventions or learning preferences in any group. However, students of some learning styles tended to perform better when engaging in certain modalities. Multiple teaching modalities may accommodate learning preferences and improve understanding of anatomy. Anat Sci Educ. © 2013 American Association of Anatomists.  相似文献

The use of two‐dimensional (2D) images is consistently used to prepare anatomy students for handling real specimen. This study examined whether the quality of 2D images is a critical component in anatomy learning. The visual clarity and consistency of 2D anatomical images was systematically manipulated to produce low‐quality and high‐quality images of the human hand and human eye. On day 0, participants learned about each anatomical specimen from paper booklets using either low‐quality or high‐quality images, and then completed a comprehension test using either 2D images or three‐dimensional (3D) cadaveric specimens. On day 1, participants relearned each booklet, and on day 2 participants completed a final comprehension test using either 2D images or 3D cadaveric specimens. The effect of image quality on learning varied according to anatomical content, with high‐quality images having a greater effect on improving learning of hand anatomy than eye anatomy (high‐quality vs. low‐quality for hand anatomy P = 0.018; high‐quality vs. low‐quality for eye anatomy P = 0.247). Also, the benefit of high‐quality images on hand anatomy learning was restricted to performance on short‐answer (SA) questions immediately after learning (high‐quality vs. low‐quality on SA questions P = 0.018), but did not apply to performance on multiple‐choice (MC) questions (high‐quality vs. low‐quality on MC questions P = 0.109) or after participants had an additional learning opportunity (24 hours later) with anatomy content (high vs. low on SA questions P = 0.643). This study underscores the limited impact of image quality on anatomy learning, and questions whether investment in enhancing image quality of learning aids significantly promotes knowledge development.

Spatial ability is an important factor in learning anatomy. Students with high scores on a mental rotation test (MRT) systematically score higher on anatomy examinations. This study aims to investigate if learning anatomy also oppositely improves the MRT‐score. Five hundred first year students of medicine (n = 242, intervention) and educational sciences (n = 258, control) participated in a pretest and posttest MRT, 1 month apart. During this month, the intervention group studied anatomy and the control group studied research methods for the social sciences. In the pretest, the intervention group scored 14.40 (SD: ± 3.37) and the control group 13.17 (SD: ± 3.36) on a scale of 20, which is a significant difference (t‐test, t = 4.07, df = 498, P < 0.001). Both groups show an improvement on the posttest compared to the pretest (paired samples t‐test, t = 12.21/14.71, df = 257/241, P < 0.001). The improvement in the intervention group is significantly higher (ANCOVA, F = 16.59, df = 1;497, P < 0.001). It is concluded that (1) medical students studying anatomy show greater improvement between two consecutive MRTs than educational science students; (2) medical students have a higher spatial ability than educational sciences students; and (3) if a MRT is repeated there seems to be a test effect. It is concluded that spatial ability may be trained by studying anatomy. The overarching message for anatomy teachers is that a good spatial ability is beneficial for learning anatomy and learning anatomy may be beneficial for students' spatial ability. This reciprocal advantage implies that challenging students on spatial aspects of anatomical knowledge could have a twofold effect on their learning.

Computer‐aided learning (CAL) is an integral part of many medical courses. The neuroscience course at Oxford University for medical students includes CAL course of neuroanatomy. CAL is particularly suited to this since neuroanatomy requires much detailed three‐dimensional visualization, which can be presented on screen. The CAL course was evaluated using the concept of approach to learning. The aims of university teaching are congruent with the deep approach—seeking meaning and relating new information to previous knowledge—rather than to the surface approach of concentrating on rote learning of detail. Seven cohorts of medical students (N = 869) filled in approach to learning scale and a questionnaire investigating their engagement with the CAL course. The students' scores on CAL‐course‐based neuroanatomy assessment and later university examinations were obtained. Although the students reported less use of the deep approach for the neuroanatomy CAL course than for the rest of their neuroanatomy course (mean = 24.99 vs. 31.49, P < 0.001), deep approach for CAL was positively correlated with neuroanatomy assessment performance (r = 0.12, P < 0.001). Time spent on the CAL course, enjoyment of it, the amount of CAL videos watched and quizzes completed were each significantly positively related to deep approach. The relationship between deep approach and enjoyment was particularly notable (25.5% shared variance). Reported relationships between deep approach and academic performance support the desirability of deep approach in university students. It is proposed that enjoyment of the course and the deep approach could be increased by incorporation of more clinical material which is what the students liked most.

Engaging in science as an argumentative practice can promote students’ critical thinking, reflection, and evaluation of evidence. However, many do not approach science in this way. Furthermore, the presumed confrontational nature of argumentation may run against cultural norms particularly during the sensitive time of early adolescence. This paper explores whether middle-school students’ ability to engage in critical components of argumentation in science impacts science classroom learning. It also examines whether students’ willingness to do so attenuates or moderates that benefit. In other words, does one need to be both willing and able to engage critically with the discursive nature of science to receive benefits to learning? This study of middle-school students participating in four months of inquiry science shows a positive impact of argumentative sensemaking ability on learning, as well as instances of a moderating effect of one's willingness to engage in argumentative discourse. Possible mechanisms and the potential impacts to educational practices are discussed.  相似文献

The paper focuses on the question of how to advance collaboration through the Web and support lifelong learning. First, the theoretical framework and architecture of a new web‐based tool, the ‘IQ Team’, is introduced. IQ Team is an interactive online assessment and support system to learn social skills needed in cooperative work, and belongs in an interactive online assessing and tutoring system, ‘IQ Form’, developed for the Finnish Virtual University. IQ Team has three main elements: (1) interactive self‐evaluation test banks, (2) online tutoring sets and (3) learning diaries. In the creation of IQ Team, the validation process was conducted with two samples (n = 259 and n = 275). The online students’ social skills in different groups were explored, and the feedback data from different user groups were analysed. The online students scored high values for social skills, and no differences were discerned between university, Open University and technical students. The qualitative data (n = 35) were collected in order to get users’ feedback of the tool. The qualitative data consisted of interviews, open‐ended questions and online discussions. The users of IQ Team reflected that the tool benefited them to become aware of their group work skills and developed their collaborative learning skills. IQ Team provides a powerful tool for online instruction and communication in higher education and in the Open University to promote joint‐regulated learning.  相似文献
