传统软件交付模式偏向于手动,软件从源码到编译、打包、测试、交付生产经历不同的形态和系统环境。手动模式效率较低,且不同环境存在差异,容易引起错误导致软件部署失败。设计基于Kubernetes容器集群环境的持续交付平台,利用容器技术的隔离特性屏蔽程序运行环境的差异,利用git、docker、Kubernetes的C/S架构模式,集成每个平台的客户端及相关构建工具,使程序在拉取项目、编译、部署过程中摆脱命令行模式,只需在持续交付平台中通过表单方式配置每个过程中所需的各项参数即可,将软件交付过程中所有操作集中到统一平台上,实现自动化交付。系统测试结果表明,持续交付平台能够自动完成软件交付工作,打通了软件交付各个环节的数据流和业务流。 相似文献

We examine the equivalence of two construct‐a‐concept‐map techniques: construct‐a‐map with created linking phrases (C), and construct‐a‐map with selected linking phrases (S). The former places few constraints on the respondent and has been considered the gold standard; the latter is cost and time efficient. Both their products and processes are compared quantitatively and qualitatively as to total accuracy score, individual proposition scores, proposition choice, map structure complexity, proposition generation rate, and proposition generation procedures. We conclude that the two mapping techniques are not equivalent: The C technique is better than the S technique in capturing students' partial knowledge, even though the S can be scored more efficiently than C. Based on their characteristics, if used as an assessment tool, the C technique is more suitable for formative assessment while the S technique is a better fit for large‐scale assessments. © 2005 Wiley Periodicals, Inc.

ASP作为目前最为流行的动态网页编程技术被广泛应用于WEB开发,由于ASP程序的源代码不需要编译,采用明文进行编写,基于ASP程序的知识产权保护一直是一个难题。微软官方免费提供了ASP脚本加密程序SCRENC．EXE,对ASP代码加密,但部分原来可正常执行的源代码在加密后常常不能使用。为了确保一个ASP程序只能经过授权后使用,可采用在源代码加入运行次数限制、时间限制、IP绑定、域名绑定、远程服务器授权、后门等多种方法来实现。通过上述多重保护措施,可有效地杜绝系统被非授权使用,从而达到ASP程序知识产权的保护． 相似文献

A within-school study of the effects of two different early literacy instructional programs on the reading proficiency of Year 1 students was undertaken in three schools in New South Wales, Australia all of which used Reading Recovery. The first program under examination was a "meaning"-oriented program used by six Kindergarten and Year 1 classrooms in the three schools. The second program, a "code"-oriented one, was implemented in the same six Kindergarten and Year 1 classrooms one year later. The code-oriented program, known as Schoolwide Early Language and Literacy (SWELL), stresses the explicit instruction of phonological awareness and the alphabetic code in context. All students, including both regular and Reading Recovery students, in the six non-SWELL classrooms were tested on four early literacy measures at the end of Year 1 when they had completed two years of schooling (comparison group). At the end of the following year, all Year 1 students in the six SWELL classrooms were tested on the same early literacy measures, when they had completed two years of schooling (experimental group). Results indicated that all regular and Reading Recovery students in SWELL classes significantly outperformed their regular and Reading Recovery counterparts in non-SWELL classes on tests measuring pseudoword decoding, reading connected text, invented spelling, and a standardised reading measure at the end of Year 1. However, Reading Recovery students as a group, whether in SWELL or non-SWELL classes, did not reach the average level of their peers on any of the four literacy measures used. Implications for the most effective combination of whole-class and tutorial programs for children at-risk of literacy failure are considered in the discussion. 相似文献

Technical engineers consider communication and writing skills to be among the most difficult aspects of their profession. Communication courses, however, are expensive, because teaching takes place in tutorial groups in which students are given feedback regularly. A computer-assisted practical that aims at diminishing the amount of effort of the lecturer while increasing the participation of the students through interactive and user-friendly courseware is described. The program is developed in the Knowledge Pro environment (MS-Windows 3). The program consists of three modules: 1) a product module which offers examples of ideal texts and criteria for them; 2) a style module which offers information on stylistic aspects such as sentence complexity, use of examples, use of connectives, spelling etc.; 3) a process module, which offers a standard procedure for planning and outlining a technical report and an example, in the form of a (hyper)text adventure.Besides, the program offers individual advice to students who face problems during the writing process. In each module the student can opt for additional examples or exercises via buttons, menus and hypertext paths. The program has been written in the Dutch language. 相似文献

Over the past several decades, there has been increasing interest in program‐ and university‐level assessment and aligning learning outcomes to program content. Curriculum mapping is a tool that creates a visual map of all courses in the curriculum and how they relate to curriculum learning outcomes. Assessment tools/activities are often included in the curriculum map. The School of Food Science, a joint program between the Washington State Univ. and the Univ. of Idaho, recently completed a curriculum mapping and assessment exercise. The goal of this exercise was to determine the alignment of the undergraduate curriculum with program learning outcomes and the degree of student mastery of these outcomes. Curriculum learning outcomes were revised from existing learning outcomes to better align with university learning outcomes and the IFT Core Competencies. All undergraduate courses were mapped to the IFT Core Competencies, and several competencies were assessed to determine student mastery. The mapping and assessment activities revealed potential gaps and redundancies in course content, as well as student ability to meet standards for competency. The results of the mapping and assessment exercises will be used to refine the content delivered to undergraduate students in the School of Food Science, with the overall goal of increasing the quality of the education provided to these students and helping them to be more prepared for a successful career in food science. 相似文献

The purpose of this study was to investigate how the use of CAI tutorial programs, incorporating advance organizers and involving various sizes of groups of subjects, would affect students' achievement scores, retention scores, and rates of learning. Used as subjects were 100 suburban high school physics students running interactive tutorial physics programs focusing on strobe simulation and displacement-time and velocity-time graphs. For fifty students (experimental group) an advance organizer program preceded each tutorial. The remaining fifty students (control group) had an advance non-organizer program preceding each tutorial. While pursuing the tutorials the students worked individually or together in groups of two, three, or four. Five days were allocated for the students to repeat the four tutorials until 90% competency level was attained. Achievement and retention were measured by individually administered paper-pencil teacher-made tests sampling the content of all four tutorials. Rate of learning was determined for groups by the number of times the first three tutorial programs were executed in order to attain 90% competency. In the two-way analysis of variance the only significant result at the 0.05 level pertained to group size. Results of the Tukey Test revealed that students working in groups of three and four on CAI tutorials had significantly better rates of learning than students working alone. No significant differences in achievement or retention were observed for the various groups. The implications for using CAI tutorials in physics point to grouping students in fours as a time saving and economic method of presenting material without significant loss of achievement or retention. 相似文献
