Student perceptions of effective lecturers: the need to recognise the role of ethnicity and choice of discipline

ABSTRACT

University student perceptions of effective teaching have been explored in previous studies, however, research is lacking regarding how perceptions of teaching efficacy vary by ethnicity and programme of study. In this study, student perceptions of effective teaching are explored between STEM (Science, Technology, Engineering, and Mathematics) and non-STEM major students of four ethnic groups: Europeans, Asians, Māori, and Pasifika. The study sample comprised 2073 students from a New Zealand university who completed a survey in 2016. Firstly, the findings indicated that non-STEM major students were more likely to report culturally knowledgeable as an important characteristic compared to STEM major students. Secondly, the distribution referring to content knowledgeable, creative, culturally knowledgeable, and passionate as characteristics of effective teaching was different between the four ethnic groups. In detail, Europeans and Māori were more likely to refer to content knowledgeable than Pasifika students, while Pasifika students were more likely to refer to culturally knowledgeable compared to Europeans. Furthermore, the highest percentage of referring to creative as a characteristic of effective teaching was for Asians, and the highest percentage of referring to passionate was for Māori students. The findings imply that lecturers should be well informed about these differences to be able to improve the quality of their teaching and student learning.     

How Levels of Interactivity in Tutorials Affect Students' Learning of Modeling Transportation Problems in a Spreadsheet

Do students learn to model OR/MS problems better by using computer‐based interactive tutorials and, if so, does increased interactivity in the tutorials lead to better learning? In order to determine the effect of different levels of interactivity on student learning, we used screen capture technology to design interactive support materials for modeling and solving the transportation problem in a spreadsheet. A controlled experiment was carried out and the results indicate a general support for the effectiveness of interactive tutorials in enhancing students’ learning of modeling concepts. However, the study also found that excessive interactivity increased the cognitive load for the students and hindered their learning by making it difficult for them to consolidate concepts, integrate previous knowledge, and create meaningful mental models of the process.     

Robust integral backstepping control for sensorless IPM synchronous motor controller

In this paper, a sensorless speed control for interior permanent magnet synchronous motors (IPMSM) is designed by combining a robust backstepping controller with integral actions and an adaptive interconnected observer. The IPMSM control design generally requires rotor position measurement. Then, to eliminate this sensor, an adaptive interconnected observer is designed to estimate the rotor position and the speed. Moreover, a robust nonlinear control based on the backstepping algorithm is designed where an integral action is introduced in order to improve the robust properties of the controller. The stability of the closed-loop system with the observer–controller scheme is analyzed and sufficient conditions are given to prove the practical stability. Simulation results are shown to illustrate the performance of the proposed scheme under parametric uncertainties and low speed. Furthermore, the proposed integral backstepping control is compared with the classical backstepping controller.     

Inverse optimal neural control of blood glucose level for type 1 diabetes mellitus patients

In this paper, inverse optimal neural control for trajectory tracking is applied to glycemic control of type 1 diabetes mellitus (T1DM) patients. The proposed control law calculates the adequate insulin delivery rate in order to prevent hyperglycemia and hypoglycemia levels in T1DM patients. Two models are used: (1) a nonlinear compartmental model in order to obtain type 1 diabetes mellitus virtual patient behavior, and (2) a neural model obtained from an on-line neural identifier, which uses a recurrent neural network, trained with the extended Kalman filter (EKF); the last one allows the applicability of an inverse optimal neural controller. The proposed algorithm is tuned to track a desired trajectory; this trajectory reproduces the glucose absorption of a healthy person. The applicability of the proposed control scheme is illustrated via simulations.     

Introduction to the special issue: an international partnership in vocational psychology and career guidance practice

This thematic issue of the International Journal for Educational and Vocational Guidance includes a selection of papers presented at the IAEVG-SVP-NCDA Symposium, entitled “Vocational Psychology and Career Guidance Practice: An International Partnership”. The articles in this special issue deal with topics that highlight the interconnection between vocational psychology and career guidance. The authors, because of their different geographical and cultural backgrounds, address these points from their own perspectives. The outcome of the general discussion that centred on these topics at the International Symposium is jointly published in a special issue of the Career Development Quarterly, Vol. 57, No. 4.     

Use of Social Emotional Learning Skills to Predict Future Academic Success and Progress Toward Graduation

This study evaluated the degree to which a range of social emotional learning skills—academic self-efficacy, academic motivation, social connections, importance of school, and managing psychological and emotional distress and academic stress— could be used as an indicator of future academic outcomes. Using a sample of 4,797 from a large urban school district, we found that high school students classified as performing in the lowest 25% of their grade reported lower social emotional skills than students classified in the top 25% of academic performers by the end of the 8th grade. Two variables, perceived importance of attending college and psychological and physical stress, accounted for nearly 26% of the variance in cumulative high school GPA after controlling for 9th-grade GPA. Finally, the results indicated that a combination of 5 social emotional learning subscales effectively discriminated between students making positive progress towards high school graduation and those identified as having dropped out of or failed more than 14% of their courses.     

Racism and the future of antiracism in education: A critical analysis of the Sewell Report

This article provides an analysis and critique of the education component of the 2021 Sewell Report on Race and Ethnic Disparities. Discussion focuses on the report’s spurious claims to objectivity, the erasure of racism and the inadequacy of its recommendations. It is suggested, however, that despite its many flaws, the Sewell Report poses challenges for those who have traditionally been aligned with antiracism in education. The article concludes by setting out a vision for a new progressive project aimed at advancing racial and cultural justice that, it is suggested, can begin to address these challenges.     

Changing South African schools?: an analysis and critique of post‐election government policy

This article provides an exposition, analysis and critique of post‐election policy concerning state schooling in South Africa. In particular the article focuses on the White Paper on the Organisation, Governance and Funding of Schools. Policy is analysed at three levels, namely the economic, ideological/discursive and the political. At the economic level it is argued that although the White Paper makes provision for redress of past inequalities, limitations in government expenditure are limiting the possibilities for reform. It will also be argued that the White Paper must be seen as the outcome of contestation between different discourses concerned with race, culture and education. Finally the White Paper has been shaped by the interim constitution as well as by political struggles within the state and civil society.     

A roadblock to social justice? An analysis and critique of the South African education Roadmap

The article provides an analysis and critique of contemporary debates concerning the quality of education in South Africa from a social justice perspective. In particular the article focuses on the Education Roadmap which has gained support from a range of stakeholders in South Africa including key members of the newly elected government. The Education Roadmap is considered in relation to dominant approaches to understanding education quality within the education literature, namely the human capital and human rights based approaches. It is argued that the Roadmap shares characteristics of both approaches although it is particularly influenced by the former. The article sets out an alternative approach based on social justice principle that, whilst developing and extending aspects of dominant approaches, is considered pertinent because it articulates with historical struggles around education in South Africa. It is suggested that although the Roadmap demonstrates limited characteristics of a social justice approach, it falls short in other key aspects and it is these aspects that must form the basis for ongoing struggles for a more equitable education system.
