Does Practical Work Really Work? A study of the effectiveness of practical work as a teaching and learning method in school science

Many within the science education community and beyond see practical work carried out by students as an essential feature of science education. Questions have, however, been raised by some science educators about its effectiveness as a teaching and learning strategy. This study explored the effectiveness of practical work by analysing a sample of 25 ‘typical’ science lessons involving practical work in English secondary schools. Data took the form of observational field notes and tape‐recorded interviews with teachers and students. The analysis used a model of effectiveness based on the work of Millar et al. and Tiberghien. The teachers’ focus in these lessons was predominantly on developing students’ substantive scientific knowledge, rather than on developing understanding of scientific enquiry procedures. Practical work was generally effective in getting students to do what is intended with physical objects, but much less effective in getting them to use the intended scientific ideas to guide their actions and reflect upon the data they collect. There was little evidence that the cognitive challenge of linking observables to ideas is recognized by those who design practical activities for science lessons. Tasks rarely incorporated explicit strategies to help students to make such links, or were presented in class in ways that reflected the size of the learning demand. The analytical framework used in this study offers a means of assessing the learning demand of practical tasks, and identifying those that require specific support for students’ thinking and learning in order to be effective.     

Does adviser mentoring add value? A longitudinal study of mentoring and doctoral student outcomes

This study of the impact of doctoral adviser mentoring on student outcomes was undertaken in response to earlier research that found (a) students with greater incoming potential received more adviser mentoring, and (b) adviser mentoring did not significantly contribute to important student outcomes, including research productivity [Green, S. G., and Bauer, T. N. (1995). Personnel Psychology 48(3): 537–561]. In this longitudinal study spanning 5 1/2 years, the effect of mentorship on the research productivity, career commitment, and self-efficacy of Ph.D. students in the ‘hard’ sciences was assessed, while controlling for indicators of ability and attitudes at program entry. Positive benefits of mentoring were found for subsequent productivity and self-efficacy. Mentoring was not significantly associated with commitment to a research career.     

The ABC of peer mentoring – what secondary students have to say about cross-age peer mentoring in a regional Australian school

Cross-age peer mentoring is an educational model that builds on peer support and mentoring to assist young people to enhance social relationships, develop cognitive skills, and promote positive identity development. In this article, we outline the evaluation process of a cross-age peer-mentoring program implemented in an Australian secondary school. This program had a distinctive focus on blending cross-age peer mentoring, academic tutoring, and social support roles. We focus on the program's consumers – the voices of Year 7 students (mentees) and Year 10 students (mentors). Student perspectives were gathered using qualitative methods through repeated focus groups. Data were thematically analysed, and the findings show observed changes in social relationships, problem-solving skills, and engagement with literacy. We discuss the importance of this relationship for effective learning and examine the reported changes to engagement with relationship building. Implications for developing whole-of-school support and increasing wider participation are discussed.     

How do students perceive the educational value of peer assessment in relation to its social nature? A survey study in Flanders

This study explores the relationship between students’ perceptions of peer assessment (PA) and its social nature. A quantitative survey study (N = 3680) was conducted in secondary education in Flanders, examining the students’ perceptions of PA interpersonal variables and their beliefs on the educational value of PA. The structural equation modeling (SEM) results show that the educational value students attribute to PA was positively predicted through trust in their own and their peers’ evaluative capabilities, awareness of negative interpersonal processes (e.g. fear of disapproval and friendship marking), and beliefs about PA accuracy. The importance attributed to anonymity appeared to be a negative predictor of PA conceptions. Tests of mean latent differences were performed to explore the differences between educational levels, PA experience and gender.     

A motivation perspective on faculty mentoring: the notion of “non-intrusive” mentoring practices in science and engineering

Scholars have offered numerous approaches and best practices for mentoring faculty, many of which have provided valuable insight into the complex nature of the mentoring process. Yet, little attention has been paid to how faculty mentoring practices can influence a mentee’s intrinsic motivation. Through a series of 15 interviews with faculty members from mathematics, engineering, and life science, coupled with the use of self-determination theory, the author demonstrates how disciplinary backgrounds influence their needs for autonomy, competency, and connectedness, which effects their intrinsic motivation to engage in scholarly work. The author highlights three themes that speak to the notion of “non-intrusive” mentoring practices that can help foster and sustain motivation, and argues that future research is needed to shed more light on how disciplinary cultures influence mentoring.     

Using and rejecting peer feedback in the science classroom: a study of students’ negotiations on how to use peer feedback when designing experiments

Background: Research on peer assessment has noted ambiguity among students in using peer assessment for improving their work. Previous research has explained this in terms of deficits in the student feedback, or differences in student views of what counts as high-quality work.

Purpose: This study frames peer assessment as a social process in the science classroom. The aim is to explore peer assessment in science education as social practice in order to contribute to an understanding of the affordances and constraints of using peer assessment as a learning tool in science education.

Design and Method: The study was conducted in four lower secondary school classes, school years 8 and 9, in two different schools. An intervention study was designed focussing on the topic of experimental design. It involved the students in a process of peer assessment where they designed experiments individually, and then exchanged their designs, conducted each other’s experiments, provided feedback to each other and revised their original design after discussing the feedback in groups. Data were collected in the form of audio recordings of student discussions and written work.

Results: The results show that, although not all peer feedback resulted in revisions, peer feedback was useful to the students in group interaction when negotiating quality in their work.

Conclusions: To conclude, the potential for using peer assessment in science education should not only be evaluated through the students’ revisions but also in terms of in what ways the feedback constitutes interactional resources for defining quality in student work.     

A study of self‐concept and social support in advantaged and disadvantaged seventh and eighth grade gifted students

Understanding differences in perceptions of self‐concept and social support among special populations of gifted learners is critical to planning appropriate services for them. The present study investigated these differences among intellectually gifted students of junior high age who were participating in full time intensive programs for the gifted. Specifically, differences as a function of gender, ethnicity, and socio‐economic class were examined. Findings indicated some differences based on ethnicity and gender, but most differences were observed between lower and higher socio‐economic groups, particularly in the areas of social support and social and behavioral self‐concept. Implications from the study would suggest attention to these dimensions in program planning.     

The architecture of peer assessment: do academically successful students make good teammates in design assignments?

This paper considers the relationship between architecture and construction management students’ overall academic abilities (as measured by Weighted Average Marks [WAMs]), their peer ratings for contributions to team design assignments (as measured by an online Self-and-Peer-Assessment [SAPA] tool), and their specific abilities as building designers (as measured by grades in individual design assignments). The research was conducted to determine whether a student’s prior academic achievements might indicate how well they will work in teams. The research demonstrates a statistically significant relationship between WAMs and SAPA ratings indicating that academically successful students more often than not make good teammates. However, the study also highlights that when peers are assessing contributions to teamwork they are assessing skills and qualities in their teammates other than overall academic ability or the ability to design well. Whilst this study is largely located within the field of design, the findings are relevant to any group work where teachers aim to design assessment that unravels group and individual contribution.     

Does desegregation matter? A comparative study of school-based social capital for university-bound minority students in segregated and desegregated school contexts of Hong Kong

Despite national policies, de facto school segregation for racial/ethnic minority students in the West and East has continued to deepen. In Hong Kong, the segregated school system was abolished in 2013, while from 2004 reformed School Places Allocation Systems encouraged minority students to choose mainstream primary and secondary schools. However, de facto ethnicity-based school segregation continues to prevail. Most minority students in the mainstream system are stuck in low-status schools where they face discrimination and institutional exclusion. This has led many of them to retreat to a limited number of schools that have traditionally catered for minority communities. Such segregation calls forth scholarly attention to the paradoxical correlation between the physical mixing of diverse students and equality of educational opportunity, especially equal access to post-secondary education (PSE)—a key for minority youth to function in the competitive labour market. This study employed the theory of school-based social capital (SBSC) and compared the ways in which PSE-relevant institutional resources and support were rationalised and enacted by staff in de facto segregated and desegregated school contexts. Case studies of two secondary schools lead us to argue that desegregation is only effective when institutional structure, culture and agents empower minority students through access to instrumental resources and support for the pursuit of PSE. The findings confound the desegregation policy and call for structural/institutional interventions to ensure instrumental SBSC is accessible to PSE-bound minority students in all schools, and thus increase the effectiveness of school desegregation.     

How to support and engage students in alternative forms of education and training? A qualitative study of school staff members in Flanders

This study focuses on how students, who for a variety of reasons struggle in mainstream secondary schools, can be supported and engaged by alternative forms of education and training to attain a (formal) qualification. Interviews and focus groups are carried out with school staff members of distinct types of alternative learning arenas in Flanders (northern part of Belgium): second chance secondary education, part-time apprenticeship track and part-time work-based vocational education. Our analyses reveal that, due to the selectiveness of mainstream secondary education, staff members in alternative learning arenas mainly struggle with the ways to develop inclusive curricula/practices and with the actual content of the curricula of their educational training or programme they are supposed to teach. Staff members struggle with putting into practice the fundamental aim to prepare socially vulnerable students for their future lives. Debates within the school team focus upon the relative importance of transferrable, specialist and social skills and competences. Results of this study are discussed to further enhance the professionalisation of school teams, and can be seen as the starting point to specify and develop the curriculum taught in both alternative learning arenas and mainstream secondary education.     

Impact in the school system of a strategy for identifying and selecting academically talented students: the experience of Program PENTA‐UC

The study explores the consequences, for participating schools, of the implementation of a system for the identification and selection of academically talented students, in the context of an extracurricular enrichment program operating at Pontificia Universidad Católica de Chile. The participants were 73 students, 50 teachers, and seven members of the school administration, in seven schools. Data were collected through interviews and focus groups. The results indicated that the identification and selection processes have mostly positive effects on teachers and students. Some potentially negative effects were also detected for the classmates of the talented students, which relate mainly to the manner in which information was handled. Possible implications of these findings for this program for talented children and other similar programs are discussed.     

Does the curriculum matter in peer mentoring? From mentee to mentor in problem‐based learning: a unique case study

Peer mentoring has been used for many years by the Nelson R. Mandela School of Medicine to integrate new students into the academic and social culture of the institution. In 2001, an unusual situation arose. A problem‐based learning (PBL) curriculum was introduced and the first cohort in this programme was mentored by senior traditional curriculum students. The present study, by canvassing the 2002 PBL mentors, set out to determine whether the mismatch in curricula impacted on students' mentoring experiences. There was overwhelming agreement that curriculum did matter—it is only when mentors are able to share the same experiences as mentees, can they fully understand student problems. Notwithstanding this and other difficulties (e.g. timetable clashes), some 2001 mentees did form bonds with their traditional curriculum mentors. Some even identified them as role models. The 2002 PBL mentors also indicated that they had undergone considerable personal development as a result of their experiences.     

A comparative study of effect of new and old science curriculum on Chinese junior high school students’ abstract thinking

“Teenagers’ abstract thinking ability test” was designed in accordance with the structure and performance of teenagers’ ability to think abstractly. 138 Chinese junior high school students who learned New curriculum and old curriculum separately were measured. A comparison between the two kinds of students shows that abstract thinking ability of the former is notably higher than that of the latter. However, the performance of differences varies by school and gender.     

What are the affective and social outcomes for low-achieving students within an inclusive school in Hong Kong?

In response to several major curriculum reforms in Hong Kong since 2000, schools were required to initiate policies that catered for learner diversity. As well academic achievement, the reforms also emphasized the affective and social outcomes of the learning experience. A whole-school approach to learner diversity includes students with low academic achievement and mild disabilities, with schools being free to develop policies and practices inline with the needs of the students, teachers, and parents. Against the Chinese cultural context, where high academic achievement is highly valued, this study describes the affective and social outcomes of students in one Hong Kong primary school that streamed students according to achievement level. Four hundred and ten students across Primary 3–5 responded to four instruments measuring academic self-concept, alienation from school, teacher–students relationship, and social integration. The responses showed that, when studying the regular curriculum, students in the low-achievement group reported greater levels of alienation and lowest levels of social integration compared with students with the highest levels of achievement. On the other hand, low-achieving students who studied a differentiated curriculum reported affective and social outcomes more consistent with the responses from the high-achieving students. The results suggest that there is a mismatch between the aims and practice of the educational policy reflecting learner diversity and the cultural expectations of both parents and students.     

Walking on egg shells: the significance of socio‐cultural factors in the mentoring of primary school students

In this article I present evidence based on primary student teachers' accounts about the way in which socio‐cultural factors in placement schools affected the quality of their experiences. I examine the proposition that school culture has a significant impact upon performance, and that the strain of adjusting to school values and expectations can lead to stress and loss of confidence for a significant minority of students. I suggest that effective mentoring needs to take close account of students' socialisation into the school culture, as failure to do so may adversely influence their teaching effectiveness and well‐being.     

Air Toxics Under the Big Sky: examining the effectiveness of authentic scientific research on high school students’ science skills and interest

Air Toxics Under the Big Sky is an environmental science outreach/education program that incorporates the Next Generation Science Standards (NGSS) 8 Practices with the goal of promoting knowledge and understanding of authentic scientific research in high school classrooms through air quality research. This research explored: (1) how the program affects student understanding of scientific inquiry and research and (2) how the open-inquiry learning opportunities provided by the program increase student interest in science as a career path. Treatment students received instruction related to air pollution (airborne particulate matter), associated health concerns, and training on how to operate air quality testing equipment. They then participated in a yearlong scientific research project in which they developed and tested hypotheses through research of their own design regarding the sources and concentrations of air pollution in their homes and communities. Results from an external evaluation revealed that treatment students developed a deeper understanding of scientific research than did comparison students, as measured by their ability to generate good hypotheses and research designs, and equally expressed an increased interest in pursuing a career in science. These results emphasize the value of and need for authentic science learning opportunities in the modern science classroom.     

What motivates students? A study on the effects of teacher leadership and students’ self-efficacy

Students’ educational motivation is significant for performance and achieving learning, but little is known about what fuels such motivation. Educational motivation is regarded as the drive and inner state that energise educational activities, facilitate learning and channel behaviour towards achieving educational goals. Educational motivation paves the way for students to learn and acquire the knowledge that is essential for successful study outcomes. This article aims to explore what determines students’ educational motivation. Building on the self-determination theory, we modelled the influence of teachers’ leadership and students’ self-efficacy on students’ educational motivation. We used survey data from a sample of upper secondary school students in Sweden; we received a total of 993 answers, equal to a response rate of 74%. The results show that students’ self-efficacy and teacher leadership are of extreme importance for students’ educational motivation, and that highly efficacious students lose most educational motivation when the teacher’s leadership is poor. The results thus support the importance of teachers’ leadership for encouraging student learning.     

The interplay of learning approaches and self-efficacy in secondary school students’ academic achievement in science

ABSTRACT

The aim of the present investigation was to analyse the role of academic self-efficacy and approaches to learning in general and in Physics and Chemistry academic achievements. The sample comprised 507 secondary school students of two Spanish schools and the study was conducted in the context of a Physics and Chemistry subject. Structural equation models showed that surface motive was the only type of learning approach directly related to performance. Besides, our models revealed that self-efficacy plays an important role as a mediating variable between the surface strategy and the deep motive learning approaches and academic achievement. Gender effects were also studied as girls showed higher levels of achievement both in general performance and in Physics and Chemistry. Implications for science education and suggestions for future research of these findings are also discussed.     

Assessing the reliability of self‐ and peer rating in student group work

Peer and self‐ratings have been strongly recommended as the means to adjust individual contributions to group work. To evaluate the quality of student ratings, previous research has primarily explored the validity of these ratings, as indicated by the degree of agreement between student and teacher ratings. This research describes a Generalizability Theory framework to evaluate the reliability of student ratings in terms of the degree of consistency among students themselves, as well as group and rater effects. Ratings from two group projects are analyzed to illustrate how this method can be applied. The reliability of student ratings differs for the two group projects considered in this research. While a strong group effect is present in both projects, the rater effect is different. Implications of this research for classroom assessment practice are discussed.
