Abstract

VERTICAL take‐off aircraft in the form of jump‐autogyros and helicopters have been under sporadic development since the first world war during which a co‐axial design attributed to von Karman was used tethered for observation purposes. Only limited success was achieved between the wars due to two main factors:

Abstract

The central job thrust for principals has been redirected in recent years from school maintenance to instructional leadership. School districts have responded to the job expectations of the 1980's by directing the principal's leadership to managing instruction. Simultaneously the research community has studied effective schools to learn what principals and teachers do that influences student achievement gains. Numerous studies have now verified that the principal indeed is a key factor in the school's attempt to alter achievement norms. In the article, we shall first synthesize the results of effective schooling characteristics that have been identified by numerous researchers. Second, we shall discuss the development of a diagnostic instrument used to assess the training needs of principals in relation to instructional leadership tasks: school planning, staff and program development, and evaluation. Finally, the results of a recent study assessing principals' perceptions of their training needs will be reported.

Abstract

THE potentialities of television in industry were referred to by this journal (March, 1954) when we reported on the Pye TV unit which had been installed in the National College of Rubber Technology, enabling shop floor demonstrations to be seen in detail by large numbers of students in the lecture theatre some way off.

Abstract

Instructional leadership has taken center stage in recent years as the emphasis on school leaders’ role in improving instructional programs and impacting student learning has increased under the pressures of the accountability movement. While there is a growing literature that has highlighted the indirect impacts of effective instructional leadership on student learning, little is known about these effects in the area of special education. Because this direct involvement in instructional and curricular matters has typically fallen outside the traditional roles of principals and other school leaders, the need for purposeful focus on developing these skills is paramount in a climate that is calling for leaders who can facilitate growth and improvement in student learning, particularly in the area of special education. This chapter explores instructional leadership in the context of special education with a focus on small to mid-sized schools. We identify a set of factors that are critical to the effective implementation of instructional leadership in the area of special education which include, communication, teacher evaluation and supervision, staff development, instructional programing, and instructional design. The chapter goes on to discuss how school leaders can cultivate growth and improvement in special education programming through the use of coaching models and distributed leadership. Lastly we explore the implications for practice including discussions of reforming principal preparation programs and shared leadership.

Abstract

Purpose

The purpose of this paper is to investigate the extent to which principals’ instructional leadership predicts teacher self-efficacy, in order to identify whether a relationship exists between principals’ perceived instructional leadership practices and teachers perceived self-efficacy in classroom management, instruction, and student engagement, while controlling for several principal, teacher, and school characteristics.

Design/methodology/approach

The data employed in this study were both teacher- and school-level data sets obtained from the Teaching and Learning International Survey, which was administered by the Organization for Economic Co-operation and Development in 2013. A two-level mixed model was employed in the analysis of the data by adding adjusted weights at both levels for the complex survey data.

Findings

The results indicated a significant and positive relationship between principals’ perceived instructional leadership practice and teachers’ self-efficacy in all three aspects. Also, gender, experience, tenure status, and formal in-service training of teachers were found to be the key factors that have significant effects on teachers’ self-efficacy perceptions.

Practical implications

Findings suggested that international effort for mandating instructional leadership in schools is a worthwhile strategy, which can help teachers develop a greater sense of ability in classroom management, instruction, and student engagement.

Originality/value

This study is the first of its kind to examine the relationship between instructional leadership and teachers’ perceived self-efficacy in multiple areas related to teaching.
