Student Perceptions of Supplemental Web-Based Instruction

This study examined the perceptions of college students using supplemental web-based instruction (WBI). During the fall quarter of 1997, the researchers surveyed higher education students in five courses at the University of Georgia. The survey included 13 five-point Likert scale questions followed by four open-ended questions. The results show that students found the supplemental WBI site beneficial, overall, to their learning while the bulletin board discussions outside of class were the most liked feature. However, most students would not consider taking a course that was conducted entirely through this medium, without any class meetings.his research interests include education, policy, and technology     

基于Web的网络教学交互模式分析

随着信息技术的出现和发展，从20世纪末开始，世界远程教育领域正涌动着一场信息技术变革的热流。“交互”、“独立”、“合作”等一些概念成为了当前的热点教育名词。其中，“交互”这一概念在基于Web的网络教学（WBI）中更是倍受关注。但是人们对WBI交互的理论认识仍然比较匮乏。因此，我们需要根据已有的一些学习和交互理论，对WBI交互进行科学的理论抽象，把握WBI的交互模式。这样才能使我们对WBI交互有深刻的认识，便于我们更好地运用这一手段为网络教学服务。

Examining the Effectiveness of an Academic Language Planning Organizer as a Tool for Planning Science Academic Language Instruction and Supports

To engage in the practices of science, students must have a strong command of science academic language. However, content area teachers often make academic language an incidental part of their lesson planning, which leads to missed opportunities to enhance students’ language development. To support pre-service elementary science teachers (PSTs) in making language planning an explicit part of their science lessons, we created the Academic Language Planning Organizer (ALPO). The purpose of this study was to determine the effectiveness of the ALPO on two levels: first, by examining participants’ interactions with the ALPO as they identified academic language features, objectives and supports; and second, by exploring the ways that participants translated identified language supports to planned science activities. Findings indicated that, when using the ALPO, PSTs identified clear language functions and relevant vocabulary terms, and also frequently developed clear, observable and measurable language objectives. When lesson planning, PSTs were largely successful in translating previously identified language supports to their lesson plans, and often planned additional language supports beyond what was required. We also found, however, that the ALPO did not meet its intended use in supporting PSTs in identifying discourse and syntax demands associated with specific academic language functions, suggesting that revisions to the ALPO could better support PSTs in identifying these academic language demands. Implications for supporting PSTs’ planning for and scaffolding of science academic language use are presented.     

Examining Online Instruction in Undergraduate Nursing Education

Web-based courses have increased in number as one of the primary modes of distance education in undergraduate nursing programs across the United States. An online survey of 171 nursing faculty in the United States with experience teaching Web-based courses served as the primary data source. Interviews and a review of course Web sites provided additional comparative information. Results of this study indicated online faculty spent significantly more time in planning and implementing a Web course than they did a traditional course. Despite this time commitment respondents perceived the teaching experience to be a successful and effective form of instruction that they felt could be used to deliver any type of nursing course. The online teaching experience was described as both collaborative and highly interactive. Most respondents indicated they preferred online teaching to traditional face-to-face instruction. This positive reaction to teaching online supports the future viability of Web-based instruction at colleges of nursing.     

关于写作教学有效性的思考

当前中小学的写作教学主要存在写作教学内容缺失、写作指导缺位、写作教学观念落后、一些作文试题的导向错误、写作体式要求失当等问题。要解决这些问题,必须把"写什么"与"怎么写"放在提高写作教学有效性的层面加以反思。首先,要理清写作目标与写作内容的关系,要规定具体的写作课程内容;其次,写作教学的重心应该转移到切实加强对学生"怎么写"的指导上。     

School Level Conditions Affecting the Effectiveness of Instruction

In this article, the current status of school level factors, as they appear in research reviews and in school effectiveness models is criticised both from a theoretical and from an empirical perspective. School level factors are often related to student achievement without taking into account the classroom level, where teaching and learning primarily take place. As a theoretical alternative, an overview of school level factors that enhance the quality of instruction, time for learning and opportunity to learn at the classroom level is provided. These factors are supposed to contribute to the explanation of differences in student achievement. Some empirical support for these ideas is found in educational research studies that have made use of three‐level analyses.

Examining the Links Between Psychoeducational Assessment,Instruction and Remediation

The assessment of students’ capabilities and learning outcomes has long been considered an important factor in instructional design and program planning and refinement. The information provided by clinicians, however, has not always been presented to classroom teachers in a form that will allow them to amend their classroom practices to the students’ advantage. This paper reviews the recent history of psychoeducational testing and examines several attempts to link assessment with instruction within the information processing domain. The authors present a case for the inclusion of testing procedures that inform teachers of students’ information processing capabilities and they argue that clinicians and educators must work together to translate these data into effective remediation and instruction practices.     

A Study of the Effectiveness of Web-Based Homework in Teaching Undergraduate Business Statistics

Web-based homework (WBH) Technology can simplify the creation and grading of assignments as well as provide a feasible platform for assessment testing, but its effect on student learning in business statistics is unknown. This is particularly true of the latest software development of Web-based tutoring agents that dynamically evaluate individual students' skill level and purport to respond with appropriate, targeted teaching to improve learning efficiency. In this article, we compare traditional, textbook-based homework assignments with three systems of WBH for undergraduate business statistics courses: ALEKS, PH Grade Assist, and custom-made online quizzes in Blackboard. These systems represent a range of media from artificial intelligence–based tutoring to instructor-controlled objective testing. Using a common assessment test, we compare the performance of students taught with these different systems. Our study finds, as we anticipated, that student performance depends significantly upon teacher experience and student academic competence. Once these factors are controlled for, however, the technique used to deliver homework makes little difference in student success. In contrast to other published research, we do not find any advantage to automated tutoring and identify some limitations of this approach based on both instructor and student feedback.

Optimizing Web-Based Instruction: A Case Study Using Poultry Processing Unit Operations

ABSTRACT:  Food companies and supporting industries need inexpensive, revisable training methods for large numbers of hourly employees due to continuing improvements in Hazard Analysis Critical Control Point (HACCP) programs, new processing equipment, and high employee turnover. HACCP-based food safety programs have demonstrated their value by reducing the number and frequency of multimillion-dollar food recalls. The focus for the future must be proactive training of plant personnel to ensure continuous improvements in plant food safety and quality. In response to this need, we developed training modules focused on applying HACCP principles, quality aspects, and production information to individual poultry unit operations. Learning objectives were evaluated using discount usability testing techniques to optimize the delivery system and to ensure a satisfactory e-learning experience. Discount usability testing of this virtual orientation was successful in obtaining vast amounts of feedback. Usability issues with the training materials were identified. Expected completion times were not met by most participants, indicating that a change in the format of the course might be necessary, perhaps segmenting the modules into smaller sections to be reviewed independently of one another. Another suggestion by the evaluators was to include narration for the sections, which might in turn speed up the completion times. A navigation error was discovered by these users, as well as other critical errors in design. Other errors, such as font inconsistencies and page design changes, were also discovered by the participants.     

Examining Estimates of Intervention Effectiveness Using Sensitivity Analysis

Making causal inferences from a quasi‐experiment is difficult. Sensitivity analysis approaches to address hidden selection bias thus have gained popularity. This study serves as an introduction to a simple but practical form of sensitivity analysis using Monte Carlo simulation procedures. We examine estimated treatment effects for a school‐based support intervention designed to address student strengths and needs in academic and nonacademic areas by leveraging partnerships with community agencies. Middle school (Grades 6–8) statewide standardized test scores in mathematics and English language arts (ELA) were examined for students in a large urban district who participated in City Connects during elementary school. Results showed that the estimated treatment effects in both subjects were reduced slightly with the inclusion of U, a hypothesized unobserved binary variable. However, simulated effects fell within one‐sided 90% confidence intervals for original treatment effects, suggesting only a mild sensitivity to hidden bias. Moreover, almost identical estimated treatment effects were observed when the magnitude of the mathematical difference between each pair of the conditional probabilities of U given the treatment indicator Z was the same.
