Technology 2000

Abstract

This article describes a collaborative university-school district project for improving teaching and learning by using state-of-the-art educational technologies. The work resulted in the simultaneous improvement of P-12 education and teacher education. The article illustrates some of the important outcomes of a project known as Technology 2000, a collaborative effort between a university, a school district, and a business partner. Through using appropriate educational technologies, pre-service teachers, in cooperation with their supervising teachers in five classrooms at two school sites, engaged in the collaborative alignment of curriculum, instruction, and assessment to facilitate student achievement. The participants believe that the outcomes of this educational technology project have important implications for improving teaching and learning in other schools and teacher education settings.     

A real options perspective on R&D portfolio diversification

This paper shows that the conditionality of investment decisions in R&D has a critical impact on portfolio risk, and implies that traditional diversification strategies should be reevaluated when a portfolio is constructed. Real option theory argues that research projects have conditional or option-like risk and return properties, and are different from unconditional projects. Although the risk of a portfolio always depends on the correlation between projects, a portfolio of conditional R&D projects with real option characteristics has a fundamentally different risk than a portfolio of unconditional projects. When conditional R&D projects are negatively correlated, diversification only slightly reduces portfolio risk. When projects are positively correlated, however, diversification proves more effective than conventional tools predict.     

Students' conditioned response to teachers' response: portfolio proponents, take note!

Portfolio advocates argue that teacher commentary becomes more meaningful for students with the use of portfolio assessment, particularly because the commentary is unaccompanied by a grade. However, my own study of portfolio classrooms suggests that students continue to regard teacher responses as directives that leave them few options in terms of revisions. My study involved six writing classrooms from the middle school to the university level and included classroom observations, interviews of students and teachers, and examination of student writing and teacher response. The students generally looked to their teachers to show them the “correct” way to write and resisted the notion of making independent judgments about their writing and the necessary revisions, primarily because they could not ignore the ultimate reality of the grade. Yet the teachers generally avoided being directive in their responses. In one instance, the teacher's best efforts to adopt a more open style of response backfired when a sensitive student read the commentary as demeaning. I argue, therefore, that even though portfolios represent a more enlightened approach to assessment, students have difficulty escaping their conditioned obeisance to teacher authority. While this finding should not be read as a condemnation of portfolio assessment, it does indicate that teachers need to be aware of how students read their responses. Otherwise, portfolios alone may not substantially alter the teacher–student dynamics.

Computer science students’ use of the internet for academic purposes: difficulties and learning processes

ABSTRACT

Higher-education students now have more alternatives for searching for information than previous generations had. The Internet is a vast ocean of information sources, albeit with diverse reliability and quality. In Web 2.0 platforms, any participant can be a content creator. This reality is challenging for both the instructors and the students. We conducted interviews with 12 Computer Science students and 8 instructors from two universities to (a) identify the difficulties students encounter, if at all, (b) identify the learning processes that students undergo, if at all, when using the Internet for their CS studies, in particular, programming tasks; and (c) elicit instructors’ perceptions of students’ use of the Internet. Both students and instructors agreed that although using the Internet is not trivial, direct teaching of this skill is unnecessary. Instructors differed in their attitudes towards students’ use of the internet. We found that in the first year the students’ use of the Internet and their difficulties are similar to reports in the empirical literature, and echo the instructors’ concerns. However, after extensive experience, students undergo a learning process, and their ability to navigate the myriad sources, as well as to search, manage, and effectively evaluate Internet sources improves. Students mentioned their improved abilities to code as a means to effectively evaluate information sources.     

Assessment of teacher competence using video portfolios: Reliability, construct validity, and consequential validity

The richness and complexity of video portfolios endanger both the reliability and validity of the assessment of teacher competencies. In a post-graduate teacher education program, the assessment of video portfolios was evaluated for its reliability, construct validity, and consequential validity. Although video portfolio facilitated a reliable and valid assessment of teacher competencies, procedures to improve assessment quality were also revealed and are therefore discussed: more explicit grounding of assessment results in the data, peer debriefing, prolonged engagement with the assessment data, cross-checking to find confirmatory or counter examples.     

基于SPOC和TBLT的《民航商务英语》教学范式探究

任务型语言教学(TBLT)的特点和职业英语教学目标高度吻合,然而在传统课堂的任务型教学中,课堂活动时间常常被知识传授时间挤压,使知识内化无法完成。由Armando Fox教授提出的SPOC模式创建了一种将MOOC和实体课堂相结合的混合教学模式,给职业英语TBLT教学带来了有益的启示。本文根据Bersin提出的混合教学的四个流程,对案例课程的课程开发和教学实践进行描述性研究,以探索基于SPOC和TBLT的职业英语教学范式。
