Guidance in inquiry-based instruction – an attempt to disentangle a manifold construct

Inquiry-based instruction is an important teaching strategy in science education that can be implemented to achieve different learning goals (e.g. the learning of science content or of inquiry skills and strategies). Inquiry-based instruction is often combined with guidance attempting to assist students to effectively engage in inquiry activities and, through this engagement, reach the intended goals. In recent research, the type and amount of guidance needed to foster student’s learninghas received considerable attention. One challenge in interpreting the results of this line of research is the manifold meanings of the term ‘guidance’ and its implementation in inquiry-based instruction. Moreover, the effectiveness of a particular type and amount of guidance may also depend on the learning goal that is to be achieved. In this paper, we draw on existing research and theoretical considerations in attempting to disentangle three major dimensions in which the implementation of guidance may vary: (a) the degree of autonomy, (b) the degree of conceptual information, and (c) the cognitive domain of guidance. We discuss how these dimensions can be used to capture and systemise fidings of existing studies as well as to infer desiderata for further research on the role of guidance in inquiry-based instruction.     

A Statistical Test for Detecting Answer Copying on Multiple-Choice Tests

A statistical test for the detection of answer copying on multiple-choice tests is presented. The test is based on the idea that the answers of examinees to test items may be the result of three possible processes: (1) knowing, (2) guessing, and (3) copying, but that examinees who do not have access to the answers of other examinees can arrive at their answers only through the first two processes. This assumption leads to a distribution for the number of matched incorrect alternatives between the examinee suspected of copying and the examinee believed to be the source that belongs to a family of "shifted binomials." Power functions for the tests for several sets of parameter values are analyzed. An extension of the test to include matched numbers of correct alternatives would lead to improper statistical hypotheses.     

Experienced teachers dealing with issues in education: a career perspective

This article reports on a qualitative study on the issues experienced teachers may encounter in everyday teaching practice. Some issues may possibly originate at the beginning of a career and continue to be a struggle during their career. Data were collected among 20 mid- and late career teachers from eight secondary schools. The results showed that at the current moment in their career, respondents of this study particularly recognised three issues: teacher–parent interaction, teaching versus other tasks and private life versus work. Teachers seldom talk about their issues, but more often than not they try to find a solution themselves or put up with the situation.     

Doctoral students’ experiences leading to completion or attrition: a matter of sense,progress and distress

A central trend in qualitative studies investigating doctoral students’ dropout is to stress the importance of students’ integration and socialisation in their working environment. Yet, few of these studies actually compared the experiences of doctoral students who completed or quit their PhD. In order to overcome this limitation and identify the factors that differentiate these two groups, the present study interviewed 21 former doctoral students: 8 completers and 13 non-completers. The results show that what best differentiates these two groups of participants is the extent to which they feel that they are moving forward, without experiencing too much distress, on a research project that makes sense to them. We assume that this set of factors is central in the dropout process. Support from doctoral peers was found to play a positive role overall but did not contribute to differentiating the two groups, presumably because peers have a limited impact on dissertation progress. Supervisors’ support was central to the participants’ stories; it is thus assumed to play a role in the process, but this role is complex and needs further investigation. These results call for a stronger consideration of the doctoral task itself when investigating the process of persistence and attrition and for a more integrated framework that considers jointly both task- and environment-related aspects.     

The development and validation of a framework for teaching competencies in higher education

In higher education, approaches to teaching are becoming more student-centred, which demands different teaching competencies. Therefore, it is necessary to have an adequate framework of teaching competencies that can be used for evaluation purposes. The weaknesses of the existing frameworks are that they do not pay attention to the person as teacher, they are too narrowly defined, they are not validated and they are not adjusted to modern approaches to teaching. The aim of this study was to develop and validate a framework of teaching competencies in higher education. A framework for teaching competencies was therefore constructed containing the following domains: The Person as Teacher, Expert on Content Knowledge, Facilitator of Learning Processes, Organiser and Scholar/Lifelong Learner. The framework was validated using a Delphi method. Educational experts (N = 63) were asked: ``How important are the following teaching competencies in each domain for an experienced teacher in higher education?'' A confirmatory factor analysis was conducted to assess the adequacy of the domains. After two rounds, the shift in ratings was minimal, so the results were considered stable. The response rate was 82%. From the original list with 134 items, 30 items were omitted because many experts failed to respond to them. The experts reached consensus on 61 out of the resulting 104 items (59%). A confirmatory factor analysis on the three best scoring items in each domain confirmed the model. A framework of teaching competencies was developed and validated that can be used as a starting point for teacher evaluation in higher education.     

Inquiry-Based Learning and the Art of Mathematical Discourse

Abstract

Our particular flavor of inquiry-based learning (IBL) uses mathematical discourse, conversations, and discussions to empower students to deepen their mathematical thinking, building on strengths of students in the humanities. We present an organized catalog of powerful questions, discussion prompts, and talk moves that can help faculty facilitate a classroom focused on mathematical discourse. The paper brings this discourse alive through classroom vignettes and explores various teacher moves and their impacts. The mathematical theme of the classroom investigations, Maypole dance patterns, stems from the learning guide “Discovering the Art of Mathematics: Dance.” Both authors are part of the NSF-funded project “Discovering the Art of Mathematics,” which provides IBL materials for mathematics for liberal arts courses, see www.artofmathematics.org.     

Temporary contracts: effect on job satisfaction and personal lives of recent PhD graduates

In this study, we assess the effects of temporary employment on job satisfaction and the personal lives of recent PhD graduates. Temporary employment is becoming increasingly prevalent in many sectors, but has been relatively common in academia, especially for early career scientists. Labor market theory shows temporary employment to have a conspicuous negative influence on the job satisfaction and well-being of employees, but also identifies groups that may be exempt from these negative influences, such as the highly educated. Here, we study the effect of temporary employment on the highest educated group in the labor force, PhD graduates. We present findings of a survey of 1133 respondents who obtained their PhD from one of five Dutch universities between 2008 and 2012. Compared to PhDs employed on a permanent contract, PhDs on a temporary contract are less satisfied with their terms of employment, especially if they have no prospect of permanence. Temporary contracts with no prospect of permanence also decrease satisfaction with job content. Conversely, self-employment increases satisfaction with job content. Educational level required for the job also influences job satisfaction to a large degree: working below PhD level negatively affects job satisfaction. Finally, the type of contract affects different aspects of the personal lives of PhDs, such as the ability to obtain a mortgage, the stability of family life, and the possibility to start a family. In conclusion, we show that the highest educated, i.e., PhD graduates are not exempt from the negative influences of temporary employment.     

Does School Admission by Zoning Affect Educational Inequality? A Study of Family Background Effect in Estonia,Finland, and Sweden

We indicate the size of family background effects in Sweden, Finland, and Estonia – countries that differ in both the rhetoric and extensiveness of the system-level school choice policies. Family background effect is defined as the dependence of student achievement on family background characteristics, such as parental education, income, and social status. The number of books at home is used as a proxy when operationalising family background, and its effect is measured as a percentage of individual-level PISA scores. Fixed-effect regression results reveal that family background remains a powerful determinant in the educational results of 15-year-old students in all three cases, being largest in Sweden. Furthermore, we show how the family background effect is moderated by school-level choice policy, that is, how students and schools are matched. The analysis reveals that zoning policies have statistically significant negative effects on the impact of the family background effect, independent of country-level policies.     

Correlates of adjustment to aging among the young-old and the oldest-old: A comparative analysis

This study aims to compare the correlates of adjustment to aging (AtA) reported by young-old and oldest-old adults and to build two structural models to explore the correlates of AtA for these two age groups. A cross-national study encompassing a community-dwelling sample of 823 older adults aged 65 years and older was undertaken. Several measures were employed to assess AtA, subjective well-being, and sense of coherence. A questionnaire to determine socio-demographic (sex, age, professional and marital status, education, household, adult children, family’s annual income, living setting, and self-reported spirituality), lifestyle and health-related characteristics (perceived health, recent disease, medication, and leisure) was also used. Structural equation modeling was employed to investigate a structural model of AtA, comprising socio-demographic, lifestyle, and health-related variables, as well as SWB and SOC for both groups. Leisure was the most significant correlate of AtA for the young-old (β = .422; p < .001) while self-reported spirituality was the most significant correlate of AtA for the oldest-old (β = .711; p < .001). Significant correlates explain 67.8% and 73.1% of the variability of AtA, respectively. The results presented in this study highlighted different perspectives of AtA, outlined in two structural models, for the groups, and the need of addressing the differences between these, when implementing health care interventions, in particular the relevance of leisure and self-reported spirituality.
