Using software simulators to enhance the learning of digital logic design for the information technology students

Making the students understand the theoretical concepts of digital logic design concepts is one of the major issues faced by the academics, therefore the teachers have tried different techniques to link the theoretical information to the practical knowledge. Use of software simulations is a technique for learning and practice that can be applied to many different disciplines. Experimentation of different computer hardware components/integrated circuits with the use of the simulators enhances the student learning. The simulators can be rather simplistic or quite complex. This paper reports our evaluation of different simulators available for use in the higher education institutions. We also provide the experience of incorporating some selected tools in teaching introductory courses in computer systems. We justified the effectiveness of incorporating the simulators into the computer system courses by use of student survey and final grade results.

用Premiere软件为MTV视频添加卡拉OK字幕的方法

提出了在Premiere中为MTV视频添加卡拉OK字幕的两种制作途径。一是直接在Premiere中制作卡拉OK字幕,在Premiere中制作又可分为重叠字幕做法、轨道蒙版键做法、彩色蒙版做法三种方法。二是结合制作卡拉OK字幕的第三方插件来制作。     

Using performance methods to enhance students' reading fluency

The quasi-experimental study examined the effects of pairing Rock and Read with Readers Theater and only Rock and Read on second grade students' reading fluency scores. The 51 subjects were pre- and post-tested on five different reading fluency measures. A series of 3 × 2 repeated measures ANOVAs revealed statistically significant interaction effects on three of the five outcome measures: expression and volume, phrasing, and pace. The analysis of simple effects showed large mean difference effect sizes in both treatments.     

Using mobile devices to enhance inquiry-based learning processes

Technological advances offer the possibility of using mobile devices to enrich learning environments with multimedia content. Although physical experiments play a key role in science learning, little is known about integrating multimedia learning in physical experimental processes, especially in realistic classroom settings. In our approach, students use tablets to investigate motion with an application providing multiple representations of the measurement data. We present the results of a cluster-randomized controlled study with high school students (average age = 15.6, N = 286) conducted between 2017 and 2018 in 11 secondary schools in Germany. Conceptual understanding of physics, cognitive load, and assessment of teacher behavior were surveyed. Multilevel regression analysis revealed that this approach leads to a significant reduction of extraneous cognitive load and to greater conceptual knowledge. A confirmatory path analysis revealed that these effects can be traced back to the treatment and are not significantly influenced by teacher behavior.     

Using grant funding to enhance school psychology training

The Office of Special Education Programs (OSEP) offers competitive grants to institutions to provide training to prepare education personnel to work with children with disabilities. These grants have been found to improve the recruitment, training, and retention of special education personnel. This study explored the use of OSEP–personnel preparation (OSEP–PP) grants in school psychology programs from the perspective of school psychology university trainers with current active OSEP grant funding. Findings suggest that OSEP–PP grants enhance school psychology program recruitment efforts and improve the training of school psychologists. Study participants highlighted the importance of diversity within both training and recruitment. On the basis of these findings, authors discuss ways in which OSEP–PP funding can improve field shortages and school psychology training, and subsequently enhance school psychology practices towards more comprehensive service delivery.     

Using video-based anchored instruction to enhance learning: Taiwan's experience

The purpose of this study is to investigate the effects of computer-assisted videodisc-based anchored instruction on attitudes toward mathematics and instruction as well as problem-solving skills among Taiwanese elementary students. Results from a t-test indicate a significant main effect on student attitudes toward mathematics. Results from a two-way Repeated Measures ANOVA show that students' problem-solving skills improve significantly with anchored instruction. Results also indicate that all the students benefit from the effects of anchored instruction on their problem-solving performance regardless of their mathematics and science abilities. The findings suggest that video-based anchored instruction provide a more motivating environment that enhanced students' problem-solving skills. This study is significant because it establishes an example of video-based anchored instruction for Taiwanese students and also provides empirical evidence of its effects on affective and cognitive responses among fifth graders in learning mathematics. This study is helpful to educators who want to help students learn to think and learn throughout technology.
