A qualitative biomechanics (functional anatomy) course is a typical course in kinesiology curriculum. Most evidence suggests that biomechanics learning could be improved with the inclusion of laboratory experiences. However, implementing laboratories into biomechanics curriculum is difficult due to cost and time constraints. This study was conducted to evaluate whether hands-on activities in lecture improve qualitative biomechanics learning. A lecture format was compared to the same course with guided and unguided hands-on activities included during lecture. Test performance and student evaluations were compared between lecture formats to determine if hands-on experiences improve learning. The hands-on group performed better on the same test questions and they evaluated their overall course activities as beneficial to their learning. The findings suggest that guided hands-on experiences may improve learning compared to unguided activities. The hands-on experiences seem to provide an embodied cognitive learning experience, facilitating retention of learned material through three-dimensional and tactile mental representations. Findings from this research are currently shaping how biomechanics is taught to students at this university and could at other universities as well.  相似文献

High school biology students who were taught by the simulation game method had comparable achievement gains to the students who were taught using worksheets. The three simulation games used in this study were able to teach factual information as well as the worksheet activities. This effect was constant across ability and sex. There were no significant differences in the retention scores of high ability students utilizing gaming. Also, there was no significant difference in the scores of low ability students utilizing worksheets and low ability students using games. Students' sex was significantly related with retention in the three-way interaction of treatment by ability by sex. Low ability females using simulation games scored higher on retention than low ability females utilizing worksheets. Low ability males utilizing worksheets scored higher on retention than low ability males using simulation games.  相似文献

Teaching and learning in outreach laboratories is suitable for completion of multiple hands-on experiences of students. Digital contents may support and further enrich individual haptic experiences. Nevertheless, individual variables such as computer-related self-concepts are supposed to intervene with the cognitive learning success within this context. This potential interrelationship was a major focus of our study completed in an outreach laboratory where an eLearning module specifically was integrated into a hands-on centered gene-technology module. By monitoring cognitive knowledge levels and simultaneously applying the computer-related self-concept of 162 German students (11th grade), an increase in knowledge became apparent independently of individual computer-related self-concepts. This missing relationship exemplarily fosters the assumption that computer-supported learning may suite every student regardless of computer-related self-concept scores.  相似文献

It is often difficult to offer food chemistry students traditional, hands‐on laboratory experiences due to lack of funds for equipment, insufficient laboratory space, or the nature of distance education. A traditional wet laboratory exercise was developed to demonstrate the effects of the physical properties of ice formation when making high‐quality sorbets, varying the amounts of sugar, water, and stabilizer. This wet lab was compared to a simulated, detective‐based crime scene investigation (CSI) of why a famous food scientist's sorbet had become a “stiff.” Forty‐six food chemistry students were randomly assigned to groups, completing either the traditional wet lab or the simulated lab 1st before completing the 2nd type of laboratory. While there were preferences for one lab over another, there were no differences in the learning outcomes between the 2 laboratory formats. Students who preferred the simulated lab felt they could move at their own pace and were able to stop and review the simulation to understand the concepts more clearly. Traditional wet lab proponents liked working in groups and having immediate access to instructors. From the initial evaluation it appears that simulations could be used as replacements for hands‐on laboratory experiences or could serve as effective introductions to laboratory principles and concepts, resulting in increased student learning.  相似文献

This study examines the relationship between precollege experiences and moral judgment development of freshman students. The sample consisted of 767 freshmen at the University of Minnesota (Twin Cities). Freshmen with low Principled Morality scores compared to those with high scores had lower mean Contemporary-Cultural, Artistic, Literary, and Academic-Conceptual Precollege Experience scores. Females had higher mean Contemporary-Cultural, Artistic, and Literary Precollege Experience scores. Males had a higher mean Jobs Precollege Experience score. For males, the Literary measure had the highest correlation with Principled Morality scores, while for females, the Artistic measure had the highest correlation.  相似文献

Most physics professors would agree that the lab experiences students have in introductory physics are central to the learning of the concepts in the course. It is also true that these physics labs require time and money for upkeep, not to mention the hours spent setting up and taking down labs. Virtual physics lab experiences can provide an alternative or supplement to these traditional hands-on labs. However, physics professors may be very hesitant to give up the hands-on labs, which have been such a central part of their courses, for a more cost and time-saving virtual alternative. Thus, it is important to investigate how the learning from these virtual experiences compares to that acquired through a hands-on experience. This study evaluated a comprehensive set of virtual labs for introductory level college physics courses and compared them to a hands-on physics lab experience. Each of the virtual labs contains everything a student needs to conduct a physics laboratory experiment, including: objectives, background theory, 3D simulation, brief video, data collection tools, pre- and postlab questions, and postlab quiz. This research was conducted with 224 students from two large universities and investigated the learning that occurred with students using the virtual labs either in a lab setting or as a supplement to hands-on labs versus a control group of students using the traditional hands-on labs only. Findings from both university settings showed the virtual labs to be as effective as the traditional hands-on physics labs.  相似文献

This study assessed the differences in the emotional intelligence of gifted adolescent students and talented adolescent students in Bahrain. The sample consisted of 80 gifted adolescent students and 80 talented adolescent students in Grades 9 through 12. A multivariate analysis of variance (MANOVA) indicates that there were significant differences in emotional intelligence levels, as measured by the Bar-On Emotional Quotient Inventory, between gifted students and talented students in Bahrain in the direction of gifted students. There were differences between the gifted and the talented students in intrapersonal, adaptability, general mood subtest, and total emotional intelligence scores. Finally, gifted males had higher total emotional intelligence scores than gifted females; talented females had higher interpersonal scores than talented males.  相似文献

Digitally simulated laboratory assessments (DSLAs) may be used to measure competencies such as problem solving and scientific inquiry because they provide an environment that allows the process of learning to be captured. These assessments provide many benefits that are superior to traditional hands-on laboratory tasks; as such, it is important to investigate different ways to maximize the potential of DSLAs in increasing student learning. This study investigated two enhancements—a pre-laboratory activity (PLA) and a learning error intervention (LEI)—that are hypothesized to enhance the use of DSLAs as an educational tool. The results indicate students who were administered the PLA reported statistically lower levels of test anxiety when compared to their peers who did not receive the activity. Furthermore, students who received the LEI scored statistically higher scores on the more difficult problems administered during and after the DSLA. These findings provide preliminary evidence that both a PLA and LEI may be beneficial in improving students’ performance on a DSLA. Understanding the benefits of these enhancements may help educators better utilize DSLAs in the classroom to improve student science achievement.

This study addresses why women are underrepresented in Computer Science (CS). Data from 1319 American first-year college students (872 female and 447 male) indicate that gender differences in computer self-efficacy, stereotypes, interests, values, interpersonal orientation, and personality exist. If students had had a positive experience in their first CS course, they had a stronger intention to take another CS course. A subset of 128 students (68 females and 60 males) took a CS course up to one year later. Students who were interested in CS, had high computer self-efficacy, were low in family orientation, low in conscientiousness, and low in openness to experiences were more likely to take CS courses. Furthermore, individuals who were highly conscientious and low in relational-interdependent self-construal earned the highest CS grades. Efforts to improve women’s representation in CS should bear these results in mind.  相似文献

Laboratory and demonstration have long been used to supplement lecture in chemistry education. Current research indicates that students are better served by laboratories which exercise the higher-order cognitive skills, such as inquiry-based laboratories. However, the time and the resources available to perform these recommended types of laboratories are continually shrinking. Due to these factors, a demonstration-laboratory was designed to allow students to make observations through demonstration rather then through hands-on laboratory. For this study, the hands-on procedures of an inquiry style laboratory were replaced by an instructor demonstration of these same procedures. A significant difference was found between student conceptual understanding before and after the experiment, indicating that students performing the laboratory experiment and students viewing the demonstration-laboratory had an increase in conceptual understanding. However, no significant difference was found between the conceptual understanding of the two groups after the experiment, indicating that students learn roughly the same from both methods and that the demonstration-laboratory at least does no harm to the students conceptually. Long-term effects on student understanding were not measured. Student opinions comparing the demonstration laboratory to a hands-on laboratory were also collected and analyzed.  相似文献

This study investigated the use of a hands-on laboratory program as a means of improving student attitude toward science and increasing student achievement levels in science knowledge. Using a posttest-only control group design, curriculum referenced objective examinations were used to measure student achievement in science knowledge, and a posttest Q-sort survey was used to measure student attitude toward science. A one-way analysis of variance compared the groups' differences in achievement and attitude toward science. Analysis of covariance was used to determine the effect of the laboratory treatment on the dependent achievement variable with attitude toward science as the covariable. The findings showed that students who had regular laboratory instruction (a) scored significantly higher (p < .01) on the objective examination of achievement in science knowledge than those who had no laboratory experiences; (b) exhibited a moderate, positive correlation (r = .406) between their attitude toward science and their achievement; and (c) scored significantly higher (p < .01) on achievement in science knowledge after these scores were adjusted on the attitude toward science covariable. There were no significant differences in achievement or attitude toward science for the limited English proficiency groups. It was concluded that laboratory instruction influenced, in a positive direction, the students' attitude toward science, and influenced their achievement in science knowledge. It was recommended that science instruction include a regular laboratory experience as a demonstrated viable and effective instructional method for science teachers. This model of science instruction has been shown to be effective with students of diverse backgrounds who live within large urban centers. J Res Sci Teach 34: 343–357, 1997.  相似文献

Based on current theories of chemistry learning, this study intends to test a hypothesis that computer modeling enhanced hands-on chemistry laboratories are more effective than hands-on laboratories or computer modeling laboratories alone in facilitating high school students' understanding of chemistry concepts. Thirty-three high school chemistry students from a private all-girl high school in northeastern United States were divided into two groups to participate in a quasi-experimental study. Each group completed a particular sequence of computer modeling and hands-on laboratories plus pre-test and post-tests of conceptual understanding of gas laws. Each group also completed a survey of conceptions of scientific models. Non-parametric tests, i.e. Friedman's one-way analysis of ranks and Wilcoxon's signed ranks test, showed that the combined computer modeling and hands-on laboratories were more effective than either computer simulations or hands-on laboratory alone in promoting students' conceptual understanding of the gas law on the relationship between temperature and pressure. It was also found that student conception of scientific models as replicas is statistically significantly correlated with students' conceptual understanding of the particulate model of gases. The findings mentioned earlier support the recent call for model-based science teaching and learning in chemistry.  相似文献

This study explores gender differences in home computer use and control beliefs relative to being able to use computers. Perceived control of computer usage was measured in 152 Grade 8 Norwegian students. One group of students ( n = 58) had no computer training and did not use computers at school. In this group, males were found to have greater perceived control of the computer as well as greater confidence in own success, compared with females. Another group of students ( n = 94) had computer training in school. No gender differences were found in this group. The results are discussed in terms of sex stereotypes and the impact of computer training.  相似文献

Learning chemistry requires students to relate chemical equations and other symbolic notation both to molecular or atomic events and to macroscopic laboratory observations and data. Traditionally, textbooks have provided symbolic notation with minimal pictures of either microscopic events or macroscopic events leaving the teacher and student to conjure these pictures from words. This paper describes the design of several CD-ROMs with very different strategies and focus for teaching general chemistry with large databases of visual information. Teacher tools for preparation facilitate the planning of more hands-on laboratory experiences and live demonstrations to develop laboratory observation skills. Presentation materials provide animations of abstract microscopic events and concepts to help teachers explain these molecular and atomic events. Students improve observation skills in laboratories with supplemental computer tutorials that mimic the decision making required for laboratory tasks in a virtual laboratory, but students reinforce the experience and learn techniques with practice in a real laboratory. New college textbooks on CD-ROM, that integrate the molecular animations and laboratory experiments with the introduction of new terms and symbolic representations, portend large changes in all textbooks.  相似文献

This paper examines whether having school students repeat a year improves their performance, focusing on learning English as a foreign language. It takes students’ English examination results from five years from a Chinese‐medium school, together with data on their learning styles and learning strategies. Drawing on local cultural and pedagogic factors, the study finds that repeating a year, far from improving scores, homogenizes the results of males and females, and, while finding a small but statistically insignificant rise in the scores of females, is detrimental to the performance of males. Repeating a year either makes no difference or a negative difference to results. It is suggested that repeating a year reproduces, sharpens and potentiates gender differences in learning and performing in English as a foreign language, and that repeating a year is the medium and outcome of gender inequality. Implications are drawn for practice.  相似文献

This paper presents an analysis of the scientific reasoning of a dyad of secondary school students about the phenomenon of dissolution of gases in water as they work on this in a simulated laboratory experiment. A web-based virtual laboratory was developed to provide learners with the opportunity to examine the influence of physical factors on gas solubility in water. An evaluation process involving 180 students revealed that the concepts connected to the dissolution of gas in water caused problems for the students even after having experimented with the virtual laboratory. To investigate the nature of learners’ reasoning about the visualised events, 13 video-recorded groups of learners were analysed. This study follows the reasoning of one group that displayed a possibly productive way of solving the problem. The results address the students’ general difficulty of discovering something that they are conceptually unprepared for within the virtual laboratory. The analysis shows how the students eventually found a way out of their dilemma by making an analogy with other dissolving processes. In effect, the analysis elucidates some of the analytical work that had to be done by the participants when collaboratively negotiating a shared meaning of a scientific concept in concord with a given task and set of instructional materials. Implications for design might be to provide the learning material with explicit hints that enable students to connect to specific phenomena related to the one investigated concept. The findings show the usefulness of video analytic research, informed by CA and ethnomethodology. This analytical framework can support design processes and provide useful information, which might identify hurdles to learning a scientific concept by simulated events and pathways to overcome these hurdles.  相似文献

ABSTRACT: Introductory Food Science courses are most often lecture-based courses, but some include limited laboratory experiences. As described in this paper, the course minimizes lecture and maximizes experiential or "hands-on" learning by using an immersion approach to teach basic concepts of food science. Additionally, it requires students to work in groups to accomplish tasks, thus providing valuable experience in working cooperatively. The course has been taught in this basic manner at Ohio State for 10 y. Analysis of pre-test and post-test results shows that none of the students pass the pre-test and 92% pass the post-test. In 2002, the average increase in scores from the pre-test to the post-test was 65.7 ± 14.7 (n = 22).  相似文献
