Effectiveness of Podcasts Delivered on Mobile Devices as a Support for Student Learning During General Chemistry Laboratories 总被引:1,自引:1,他引:0
Chemistry instructors in teaching laboratories provide expert modeling of techniques and cognitive processes and provide assistance to enrolled students that may be described as scaffolding interaction. Such student support is particularly essential in laboratories taught with an inquiry-based curriculum. In a teaching laboratory with a high instructor-to-student ratio, mobile devices can provide a platform for expert modeling and scaffolding during the laboratory sessions. This research study provides data collected on the effectiveness of podcasts delivered as needed in a first-semester general chemistry laboratory setting. Podcasts with audio and visual tracks covering essential laboratory techniques and central concepts that aid in experimental design or data processing were prepared and made available for students to access on an as-needed basis on iPhones® or iPod touches®. Research focused in three areas: the extent of podcast usage, the numbers and types of interactions between instructors and student laboratory teams, and student performance on graded assignments. Data analysis indicates that on average the podcast treatment laboratory teams accessed a podcast 2.86 times during the laboratory period during each week that podcasts were available. Comparison of interaction data for the lecture treatment laboratory teams and podcast treatment laboratory teams reveals that scaffolding interactions with instructors were statistically significantly fewer for teams that had podcast access rather than a pre-laboratory lecture. The implication of the results is that student laboratory teams were able to gather laboratory information more effectively when it was presented in an on-demand podcast format than in a pre-laboratory lecture format. Finally, statistical analysis of data on student performance on graded assignments indicates no significant differences between outcome measures for the treatment groups when compared as cohorts. The only statistically significant difference is between students who demonstrated a high level of class participation in the concurrent general chemistry lecture course; for this sub-group the students in the podcast treatment group earned a course average that was statistically significantly higher than those in the lecture treatment group. 相似文献

Massive open online courses (MOOCs) face persistent challenges related to student performance, including high rates of attrition and low student achievement scores. Previous studies that have examined the performance of students in MOOCs have done so using qualitative analysis and the quantitative analysis of small samples. This study is the first to examine general course features of MOOCs on a large scale and to quantify the influences of these course features on student performance. Informed by the theory of web-based online instruction, this study used two-stage K-means clustering to analyze more than 200 MOOCs that had enrolled about 300,000 students, identifying three patterns of course features among the MOOCs. A MANOVA test and follow-up statistical tests revealed that these patterns of course features influenced the MOOCs’ dropout rates and student achievement scores to statistically different degrees. The implications of these findings are discussed. 相似文献

This paper is a report of an investigation in which mobile technologies were used during large lecture-type sessions in tandem with the Textwall? software. This online program is able to receive and present messages from students’ devices that the lecturer may then share. It also can be used to collect student votes on multiple-choice questions, facilitating dynamic formative assessments during class. A study has been undertaken around the MyWallMate mobile application. This program has been developed by Liverpool John Moores University to expedite the process of sending messages and votes to Textwall?. Results of this study indicated that students had a positive reaction to both Textwall? and the MyWallMate application. They reported being more comfortable in expressing their opinions via the MyWallMate mobile application and felt that using mobile technology within their lectures enhanced their learning. It has been concluded that the use of mobile technologies and BYOD-type approaches are avenues worth further exploration in global higher education. 相似文献

Advocates of ubiquitous computing have long been documenting classroom benefits of one-to-one ratios of students to handheld or laptop computers. The recent sophisticated capabilities of the iPod Touch, iPhone, and iPad have encouraged further speculation on exactly how K–12 teaching and learning might be energized by such devices. This paper summarizes the research-to-date on mobile learning for K–12 students, and then delineates specific features and applications available on the iPod Touch that might impact student learning across the curricula. Finally, caveats are offered regarding the introduction and assimilation of these handheld computers into K–12 schools. 相似文献

Testing aids, including student-prepared testing aids (a.k.a., cheat sheets or crib notes) and open-textbook exams, are common practice in post-secondary assessment. There is a considerable amount of published research that discusses and investigates the impact of these testing aids. However, the findings of this research are contradictory and inconclusive. The current meta-analytic investigation provides a general measure of the impact of both student-prepared testing aids and the use of open-textbook exams on student exam performance in post-secondary education, while examining variables that may moderate the effects of testing aids on student exam performance. The results indicate that, overall, testing aids can produce a moderate impact on student exam performance, with student-prepared testing aids associated with a larger effect (d=.402) relative to open-textbook exams (d = 0.257). The results are discussed in terms of their implications for college course instructors and for informing the broader debate about the role of testing aids in long-term student learning and mastery of course material. 相似文献

This study explored negative emotional, behavioral, and academic performance outcomes for highly mobile students and potential protective factors. Participants were fourth and fifth-grade students (N = 647, 51% male) from three schools with low socioeconomic status, highly mobile student populations within a large, suburban school district in the midwestern United States. Data were collected through student self-report surveys, teacher-report surveys, and school records. Multilevel moderation analysis tested whether school connectedness (SC) or social and emotional competence (SEC) acted as protective factors for highly mobile students, moderating the effect of school mobility on emotional problems and academic performance. Student mobility was associated with more emotional problems and lower academic performance. In contrast to past research, there was not an association between mobility and behavior problems. Although they did not act as protective factors, SC and SEC were independently associated with fewer emotional problems and stronger reading performance for all students, controlling for mobility. Results build on existing evidence that student mobility has negative effects on emotional and academic outcomes and lend support for interventions focused on enhancing SC and SEC of all students, including those at increased risk due to high mobility. 相似文献

A pre- and post-test quasi-experimental design was used to test the impact of a 30-week, theoretically-based social and emotional learning (SEL) curriculum, The RULER Feeling Words Curriculum (“RULER”), on the academic performance and social and emotional competence of 5th and 6th grade students (N = 273) in fifteen classrooms in three schools. Academic performance was assessed by report card grades. Social and emotional competence was assessed with teacher reports of student behavior. Students in classrooms integrating RULER had higher year-end grades and higher teacher ratings of social and emotional competence (e.g., leadership, social skills, and study skills) compared to students in the comparison group. This study provides preliminary empirical evidence that SEL programs like RULER improve important student outcomes. 相似文献

Research on the utilization of the Web for complex fine motor skill learning that involves whole body movements is still scarce. The aim of this study was to evaluate the impact of the introduction of a multimedia web-based learning environment, which was targeted at a rhythmic gymnastics routine consisting of eight fine motor skills, into an undergraduate course in a physical education department, as a complementary tool to campus-based instruction. The impact was evaluated in terms of: acquisition of knowledge regarding the routine skills by students, improvement of students’ ability to execute the routine, and students’ responses to the environment. The study followed a pretest/posttest experimental design and involved 76 students randomly split into two groups: The Multimedia Web-based Learning Group (MWLG) students (N?=?38), who attended campus-based instruction on the routine and also used the environment in their own space and time, and the Traditional On-site Instruction Group (TOIG) students (N?=?38), who only attended campus-based instruction. The research data were gathered through student questionnaires and ratings of students’ performances. It was found that the use of the environment as a supplement to campus-based instruction increased the effectiveness of this instruction as regards the cognitive component of motor skill learning (i.e. acquisition of knowledge regarding the routine skills) and was well-accepted by the students, although it did not have any significant contribution to the physical component of motor skill learning (i.e. performance of the routine skills). These findings partially support the future wider adoption of multimedia web-based learning environments within physical education and other academic disciplines that involve complex fine motor skill learning. Relevant implications are discussed. 相似文献

Adult students have become the new majority in online distance education. Research in online distance education, however, is still predominantly based on the historical perspective of the traditional student profile. This study examines adult students' learning engagement in online courses and explores the impact of online course design models and the type of online discussion on adult students' self-perceived and observable learning performance. The study findings inform that age itself does not predict adult students' learning satisfaction and performance. Instead, an integrated course model promotes learning satisfaction, while a Content + Support course model reinforces knowledge–constructive online interactions. The study findings also indicate disadvantages of close-ended discussion tasks in supporting students' online learning success. 相似文献

In an undergraduate Calculus III class, we explore the effect of “flipping” the instructional delivery of content on both student performance and student perceptions. Two instructors collaborated to determine daily lecture notes, assigned the same homework problems, and gave identical exams; however, compared to a more traditional instructional approach, the flipped instructor utilized videos to communicate more procedural course content to students out-of-class, with time in-class spent on more conceptual activities and homework problems. Findings from two semesters indicate similar performance on more procedural problems and small to moderate gains for the flipped students (N = 74) over their traditional counterparts (N = 77) on more conceptual exam problems. However, student perceptions remain mixed, with flipped students reporting increased communication during class but traditional students perceiving more effective use of class time, despite the gains in performance for flipped students. 相似文献

The recent emphasis in higher education on both student engagement and online learning encouraged the authors to develop an active e-learning environment for an introductory geohazards course, which enrolls 70+ undergraduate students per semester. Instructors focused on replicating the achievements and addressing the challenges within an already established face-to-face student-centered class (Brudzinski and Sikorski 2010; Sit 2013). Through the use of a learning management system (LMS) and other available technologies, a wide range of course components were developed including online homework assignments with automatic grading and tailored feedback, video tutorials of software programs like Google Earth and Microsoft Excel, and more realistic scientific investigations using authentic and freely available data downloaded from the internet. The different course components designed to engage students and improve overall student learning and development were evaluated using student surveys and instructor reflection. Each component can be used independently and intertwined into a face-to-face course. Results suggest that significant opportunities are available in an online environment including the potential for improved student performance and new datasets for educational research. Specifically, results from pre and post-semester Geoscience Concept Inventory (GCI) testing in an active e-learning course show enhanced student learning gains compared to face-to-face lecture-based and student-centered courses. 相似文献

This study examines how student practice of scientific argumentation using socioscientific bioethics issues affects both teacher expectations of students’ general performance and student confidence in their own work. When teachers use bioethical issues in the classroom students can gain not only biology content knowledge but also important decision-making skills. Learning bioethics through scientific argumentation gives students opportunities to express their ideas, formulate educated opinions and value others’ viewpoints. Research has shown that science teachers’ expectations of student success and knowledge directly influence student achievement and confidence levels. Our study analyzes pre-course and post-course surveys completed by students enrolled in a university level bioethics course (n = 111) and by faculty in the College of Biology and Agriculture faculty (n = 34) based on their perceptions of student confidence. Additionally, student data were collected from classroom observations and interviews. Data analysis showed a disconnect between faculty and students perceptions of confidence for both knowledge and the use of science argumentation. Student reports of their confidence levels regarding various bioethical issues were higher than faculty reports. A further disconnect showed up between students’ preferred learning styles and the general faculty’s common teaching methods; students learned more by practicing scientific argumentation than listening to traditional lectures. Students who completed a bioethics course that included practice in scientific argumentation, significantly increased their confidence levels. This study suggests that professors’ expectations and teaching styles influence student confidence levels in both knowledge and scientific argumentation. 相似文献

As a result of the ever-growing list of course technologies and software programs, higher education faculty and administration often debate which new tools are most valuable to students. This article investigates whether the use of an online textbook supplemental program (MindTap®) has a positive influence on student performance. The impact of goal achievement orientations is also discussed and factored into the analysis, as it provides insight into the motivations that drive the usage of online supplemental course materials. Results found that usage of MindTap® is positively predicted by a mastery approach goal orientation. More importantly, it was shown that usage of MindTap® positively predicts student performance, above and beyond the impact of age, gender, SAT score and goal achievement orientation. 相似文献

Developing plant identification skills is an important part of the curriculum of any botany course in higher education. Frequent practice with dried and fresh plants is necessary to recognize the diversity of forms, states, and details that a species can present. We have developed a web-based assessment system for mobile devices that is able to pose appropriate questions according to the location of the student. A student’s location can be obtained using the device position or by scanning a QR code attached to a dried plant sheet in a herbarium or to a fresh plant in an arboretum. The assessment questions are complemented with elaborated feedback that, according to the students’ responses, provides indications of possible mistakes and correct answers. Three experiments were designed to measure the effectiveness of the formative assessment using dried and fresh plants. Three questionnaires were used to evaluate the system performance from the students’ perspective. The results clearly indicate that formative assessment is objectively effective compared to traditional methods and that the students’ attitudes towards the system were very positive. 相似文献

This short report identifies the academic and environmental experiences that support the reclaiming of students at high academic risk and describes an applicable school‐wide programme emanating from the call for educational change in Israel. The proposed structured academic programme demonstrates how schools can achieve broad student knowledge and set high performance standards while accommodating diverse student needs. As such, the programme provides school practitioners with intervention targets that promote school engagement and higher school performance. In addition, the report provides illustrative examples of the implemented programme within schools for students at high academic risk in Israel. It is argued that a movement towards an adaptive model of schooling as portrayed within the structured academic programme may prove to be effective in academically engaging students at academic risk, thus providing all students with democratic possibilities for learning and knowing. 相似文献

While statistics is an essential topic for business students, many students experience barriers to successful learning due to anxiety, motivation, or difficulty with quantitative understanding. This research examines the use of online videos with an effort to explore the relationship between student characteristics, video usage, and course performance measures. In addition, the study examines student perceptions of the supplemental resources in an effort to examine the efficacy related to student learning and performance. This study seeks to confirm previous research regarding the benefit of supplemental video resources and extend the knowledge base by understanding the impact for various types of students (e.g., level of course, level of previous academic performance, etc.). The study found that the use of the video resources varies based on students’ previous math performance and the difficulty of the material. Student ratings indicate that the videos were helpful in learning the content and that they provided an important resource when students needed additional tools to master the material. Analysis of the results provides implications for understanding how different students use online videos and offers recommendations for educators and researchers about how to enhance student success in difficult statistics coursework. 相似文献

Students often are overconfident when they predict their performance on classroom examinations, and their accuracy often does not improve across exams. One contributor to overconfidence may be that students did not have enough experience, and another is that students may under-use their knowledge of prior exam performance to predict performance on their upcoming exams. To evaluate the former, we examined student prediction accuracy across 13 exams in an introductory course on educational psychology. For the latter, we computed measures that estimate the extent to which students use the prior exam score when predicting performance and whether students should use the prior exam scores. Several outcomes are noteworthy. First, students were overconfident, and contrary to expectations, this overconfidence did not decline across exams. Second, students’ prior exam scores were not related to subsequent predictions, even though prior exam performance showed little bias with respect to predicting future performance. Thus, students appear to under-use prior performance despite its utility for improving prediction accuracy about future exam performance. 相似文献

The Moodle platform has been used to put into practice an ongoing evaluation of the students’ Physics learning process. The evaluation has been done on the frame of the course General Physics, which is lectured during the first year of the Physics, Mathematics and Electronic Engineering Programmes at the Faculty of Science and Technology of the University of the Basque Country (UPV/EHU). A test bank with more than 1000 multiple-choice questions, including conceptual and numerical problems, has been prepared. Throughout the course, the students have to answer a 10-question multiple-choice test for every one of the blocks the course is divided in and which were previously treated and worked in the theoretical lectures and problem-solving sessions. The tests are automatically corrected by Moodle, and under certain criteria, the corresponding mark is taken into account for the final mark of the course. According to the results obtained from a statistical study of the data on the student performances during the last four academic years, it has been observed that there exists an actual correlation between the marks obtained in the Moodle tests and the final mark of the course. In addition, it could be deduced that students who have passed the Moodle tests increase their possibilities of passing the course by an odds ratio close to 3. 相似文献

This article reports a case study describing how the principles of a cognitive apprenticeship (CA) model developed by Collins,
Brown, and Holum (1991) were applied to a graduate course on performance systems analysis (PSA), and the differences this
application made in student performance and evaluation of the course compared to the previous semester. I analyzed the requirements
for the CA learning environment and identified the contributions of instructor, students, and the course based on those requirments.
I then applied the findings to create an authentic learning environment based on CA principles. In this case the students
became performance consultants, immersed in practical application of the PSA content and methodology to authentic organizational
performance issues provided by real clients. Finally, I compare student evaluation of the course to student evaluations in
the previous semester, and report their responses to a set of open-ended questions concerning the application of CA principles. 相似文献
