Learning for Vocation Apprentice Participation in Work Practice

The high drop-out rate in upper secondary education is a major challenge to European and US educational programmes. Upper secondary education in Norway faces a similar challenge, because in recent decades, around one-third of the students drop out of the educational programmes. The majority of the drop-outs are students in vocational programmes, and a substantial number are apprentices at the workplace. With these high drop-out rates and the ensuing personal, social and economic consequences, it is vital to address how upper secondary education systems can keep students connected throughout the programmes. By thoroughly analyzing learning environments and the experiences, interactions and processes which youth deal with during vocational education, insights into how characteristics of the learning environments relate to dropping-out and connectedness may be brought into educational discussions. The case study presented in this article explores how workplaces constitute learning environments and how apprentices participate in the learning environments of work according to their dispositions, aims and life plans. The findings show that the apprentices had different agencies and that they were involved in two distinct participation patterns at the workplace： a collaborative pattern and an executive pattern. Our findings also suggest that strong agency for the vocation may keep apprentices connected throughout the educational programme, although they are aftbrded an executive participation pattern. Based on our findings, it is appropriate to raise questions as to whether an unclear agency for the vocation, together with affordance of executive participation patterns, may suggest one possible answer for the high drop-out rate among apprentices.

缘份让我们走到一起

娇说过我是天空的孩子,蓝得有些忧伤。或许是性格吧,我一直很相信缘份,相信是缘份让我们走在一起,而你却更相信是我们让自己走在一起。开始时有些生气,不喜欢你这么直接地反驳我,但后来倒也想通了,缘由天定,份在人为,加起来不就是缘份吗?

例谈运用多媒体渗透修辞手法教学的尝试

小学生虽然还没有系统学习修辞知识的条件,但作为语言精粹的修辞现象还是大量存在于教材文本中,其中比喻、拟人、排比、对偶、夸张、反问、设问等常见的修辞手法更是屡见不鲜。虽然小学生在学前的生活中就接触了＂像苹果一样的小脸蛋＂这样类似的修辞口语,在课堂学习中又时不

3DV quality model based depth maps for view synthesis in FTV system

Depth maps are used for synthesis virtual view in free-viewpoint television (FTV) systems.When depth maps are derived using existing depth estimation methods,the depth distortions will cause undesirable artifacts in the synthesized views.To solve this problem,a 3D video quality model base depth maps (D-3DV) for virtual view synthesis and depth map coding in the FTV applications is proposed.First,the relationships between distortions in coded depth map and rendered view are derived.Then,a precisely 3DV quali...     

Area-time associated test cost model for SoC and lower bound of test time

A novel test access mechanism (TAM) architecture with multi test-channel (TC) based on IEEE Standard 1500 is proposed instead of the traditional sub-TAM structure. The cost model of an area-time associated test and the corresponding lower bound of system-on-chip (SoC) test time are established based on this TAM architecture. The model provides a more reliable method to control the SoC scheduling and reduces the complexity in related algorithm research. The result based on the area time associated test cost model has been validated using the ITC’02 test benchmark.
