Teachers’ professional development for differentiated instruction in mixed-ability classrooms: investigating the impact of a development program on teachers’ professional learning and on students’ achievement

The present article reports the results of a study performed to investigate and examine the characteristics of a teachers’ professional development program (Teachers’ Professional Development Program for Differentiated Instruction [PDD]) specially designed to support teachers in the design and application of differentiated instruction. Considering the characteristics of high-quality professional development programs (i.e. active learning, collective participation, closely related to the curriculum and the existing teaching realities, sufficient duration and continuance), the PDD aimed to facilitate change in both attitudes and practices of the participants. The study provides evidence of the success of the program, both in terms of teacher professional development and student achievement, and discusses the elements that made this program successful.     

Measuring teachers’ perceptions about differentiated instruction: The DI-Quest instrument and model

Within a democratic and multicultural society, diversity is a reality, and differences between students are a fact which teachers have to deal with on a daily basis. Differentiated instruction aims to meet these differences in learning in order to provide all students with the best possible learning opportunities. However, to date no validated instruments exist to measure teachers’ perceptions of differentiated instruction and their related classroom practices. This study, therefore, examined the factor structure and reliability of the Differentiated Instruction Questionnaire, called the DI-Quest instrument. A list of 87 items was constructed, building on existing prevalent theoretical models of Differentiated Instruction (e.g. Tomlinson, 2014; Hall, 2002). An exploratory and confirmatory factor analysis was undertaken to investigate the factor structure of the questionnaire. As a result, five factors emerged: two factors related to the teachers’ philosophy of differentiated instruction (the teachers’ mindset and their ethical compass), two factors referred to the practical principles that teachers apply to differentiate (flexible grouping and output = input) and the last factor (differentiated instruction) covered the self-reported extent to which teachers differentiated their instruction related to three types of differences in learning (students’ interests, readiness and learning profile). As a result, the DI-Quest instrument entailed 31 items with a five-factor structure indicating a good fit (CFI = 0.919; TLI = 0.911; RMSEA = 0.041 [0.037–0.044 – 90% confidence interval, p(0.05) = 1.000]; SRMR = 0.048; χ² = 5888.338, df = 465, p = 0.000). In addition, assuming theoretical relatedness between the factors, the validation of a DI-Quest model was empirically validated. We compared the model fit for two models by investigating which model had a lower BIC and AIC value and by comparing their chi square values. The best-fitting DI-Quest model showed four factors (teachers’ mindset, ethical compass, flexible grouping and output = input as dependent variables) functioning as significant predictors of the fifth factor (the self-reported adoption of Differentiated Instruction, which served as an independent variable). Moreover, this paper also discusses the psychometric properties of the DI-Quest instrument and the implications of the model for schools, educators and researchers.     

The impact of direct experience on preservice teachers’ self-efficacy for teaching in inclusive classrooms

With current inclusion trends, teacher educators are challenged to redesign their programmes to prepare preservice teachers to educate a wide range of students in whole-class settings. This quantitative study examined the impact of an inclusion course and a field experience on preservice teachers' self-efficacy for teaching in inclusive classrooms. Based on data collected from 141 participants, the results indicated that both the inclusion course and the field experience produced significant gains in self-efficacy. Participants with prior experience with people with exceptional needs had significantly higher levels of self-efficacy than those without prior experience; however, both groups experienced significant gains after the course and the field experience. Also, the results showed that, during the field experience, as preservice teachers spent more time with direct, individual instruction with students with exceptional needs, and less time with observation and whole-class instruction, their self-efficacy was more likely to increase. Findings were discussed, and implications for practice and future research were suggested.     

Union gives strength: mainstream and special education teachers’ responsibilities in inclusive co-taught classrooms

Co-teaching has gained considerable interest as a means of promoting the inclusion of students with disabilities in mainstream education. Nowadays, there is a consensus among researchers that co-teaching should provide effective education to all students in a mainstream class. This study aims to explore co-teachers’ attitudes towards co-teaching responsibilities in Greek mainstream classrooms. In particular, it examines co-teachers’ attitudes with regard to their non-class-time (planning and evaluation) and class-time (instruction and behaviour management) responsibilities for students with and without disabilities. Four hundred co-teachers participated in this survey study. Overall, our findings demonstrate that mainstream education teachers and special education teachers disagree about their respective class-time and non-class-time responsibilities, and that their role influences their attitudes towards these responsibilities. The study concludes that the different attitudes of co-teachers towards their responsibilities could hinder the development of a shared approach in teaching students with and without disabilities in inclusive classrooms.

The development and initial validation of a questionnaire of inclusive teachers’ competency for meeting special educational needs in regular classrooms in China

The aim of this study was to develop and validate an instrument of inclusive teachers’ competencies for teaching students with special educational needs in China. Data were obtained from a preliminary and large-scale investigation in Beijing. The primary analyses included exploratory factor analysis and confirmatory factor analysis. The findings indicated that Chinese inclusive teachers’ competency is underpinned by four factors: teaching and instruction; communication and cooperation; attitudes and beliefs; and reflection and development. The four-factor model was obtained with satisfactory reliability and validity. The validated questionnaire generated a theoretical understanding of inclusive education teachers’ competency in China. In addition, the findings of the study provided knowledge that will allow for the development of professional standards and teacher education programmes for inclusive education.     

In-service teachers’ attitudes,concerns, efficacy and intentions to teach in inclusive classrooms: an international comparison of Australian and Italian teachers

The paper examined whether in-service teachers from Australia to Italy differ in terms of their attitudes, concerns, efficacy beliefs and intentions to include learners with disabilities in their classrooms. An attempt was also made to determine predictors of the participants’ intentions to include learners with disabilities in their classrooms. Participants for the study consisted of 153 Australian and 156 Italian in-service teachers. Results revealed that Italian teachers had significantly more positive attitudes, lower degree of concerns and higher level of intentions to implement inclusion in their classrooms. In both countries, attitudes and efficacy emerged as significant predictors of participants’ intentions to include learners with disabilities in regular classrooms. Reasons that could explain differences in the teachers’ beliefs from the two countries are explained using historical-cultural and legal frameworks prevalent in Australia and Italy. Implications of the findings for policy-makers, university teachers and researchers are presented that may have relevance in guiding the implementation of inclusive education in Australia, Italy and beyond.     

Measuring teachers’ knowledge of vocabulary development and instruction

This article describes the development of an instrument to measure teachers’ knowledge of vocabulary development and instruction, the Teacher Knowledge of Vocabulary Survey (TKVS). This type of knowledge has become increasingly important as all classroom teachers are expected to help students meet language and literacy standards that include vocabulary acquisition. While a few studies have measured teacher knowledge of reading, there are no known instruments for measuring teachers’ knowledge of vocabulary development and instruction. However, vocabulary is a crucial determinant of reading comprehension and content area knowledge, particularly for English learners (Graves, August, & Mancilla-Martinez, 2013). Statements about vocabulary development and instruction were gathered from foundational texts, reviewed by subject matter experts, and researched in cognitive labs for possible inclusion as items in the TKVS. The survey’s 52 statements comprise 6 categories, including one section on vocabulary development, four sections on instruction, and one section on instruction specifically for English learners. Ratings of item difficulty by subject matter experts were then used to distinguish three levels of teacher knowledge of vocabulary: emergent, intermediate, and expert. Fifty teachers completed the TKVS, and their performance was found to correlate with the experts’ predicted difficulties of the items. Initial analyses provide evidence for the content and construct validity of the TKVS as a measure of teacher knowledge of vocabulary development and effective instruction. The discussion considers implications for the use of the instrument, including as a needs assessment or guide for professional development for both preservice and inservice teachers.     

Data-based differentiated instruction: The impact of standardized assessment and aligned teaching material on students’ reading comprehension

The paper analyzes the efficacy of a data-based differentiated instruction (DBDI) intervention in addressing growing achievement-related heterogeneity in school. The intervention consisted of a reading strategy training conducted by teachers, in which 27 secondary-school classes (n_students = 656) participated. The propensity-matched control group consisted of another 27 classes (n_students = 558). Linear mixed models showed that students of the intervention classes had no greater gain in reading competence on average compared to students of the control classes. However, the groups differed regarding the learning gain at different achievement levels. In the control group, the gain was greatest for the low achievers and lowest for the high achievers. This imbalance was not found in the intervention group, where the learning gain was similar for students of each achievement level. This shows that DBDI is a tool for addressing achievement-related heterogeneity which empowers teachers to cater to the differences between students.     

The role of environmental factors in beginning teachers’ professional learning related to differentiated instruction

Little research has investigated factors that facilitate beginning teachers’ participation in professional learning activities related to differentiated instruction (DI). This study examines environmental factors for DI learning activities in a sample of 272 beginning teachers from 72 primary schools. Multilevel analyses show that teacher education, reflective dialogue, deprivatized practice, educational type, and diversity in student population are related to beginning teachers’ use of DI learning activities (i.e., learning in interaction and changes in practice). As such, the findings revealed that beginning teachers’ participation in such activities may depend on a multitude of factors. Several suggestions regarding these factors are made. First, teacher education can provide foundational knowledge of DI applications. Second, schools can enable teachers to have in-depth conversations with colleagues and provide opportunities to observe good teaching practices. Lastly, alternative schools and schools with diverse student populations can inspire other schools to enhance participation in DI learning activities.     

Student teachers’ practice and experience with differentiated instruction for students with higher learning potential

This article presents a qualitative study concerning student teachers’ understanding of differentiation for high-achieving secondary school students with higher learning potential. Predominantly using focus group interviews of Norwegian student teachers (N = 322), this study identified their understanding of the use and value of differentiation, drawing from their teaching practice and experience. This study supports the notion that student teachers lack confidence in enacting differentiation, despite being aware of its importance, when working with these students. We contend that teacher education needs to pay more attention to helping student teachers effectively differentiate to meet the needs of high-achieving students with higher learning potential.     

Teachers’ self-reported knowledge regarding English learners: perspectives on culturally and linguistically inclusive instruction and intervention

Student diversity within U.S. schools has steadily increased in recent years. This trend has driven significant interest, on the part of schools and school systems, in supporting students who are English learners (ELs) and who are culturally diverse. It has also highlighted, for those schools and school systems, the importance of professional development to prepare teachers to support those students effectively. Teacher experience and knowledge regarding this population is particularly important to the cause of inclusive education, as appropriate supports, instruction and inclusion for these learners are highly dependent on teachers’ knowledge and skills. This study surveyed teachers in three highly diverse elementary schools with high percentages of ELs, students of minority backgrounds, and students receiving free and reduced-price meals. Results indicated that, despite reporting significant previous professional development on cultural and language diversity, teachers lacked familiarity with basic concepts related to cultural and language diversity and to factors considered in the interventions process for diverse learners. These findings, if replicated, may call into question the efficacy of ongoing professional development efforts and underscore the need for more consistent design, delivery, and evaluation of professional development initiatives or programmes.     

Challenging control: inclusive teachers’ and teaching assistants’ discourse on students with challenging behaviour

Describing students with disabilities as presenting ‘challenging behaviour’ is common in US schools. The purpose of this paper is to reveal the discourse utilised by teachers in order to understand their beliefs and practices surrounding young students considered to present challenging behaviour. This study examines teachers’ language in four ways: which discourses they draw from, the consequences of engaging in the discourse on practice, what maintains the use of such discourse and finally the possibilities for change. The critical discourse analysis unpacked that teachers begin labelling the students as challenging, not the behaviour. Consequences of this thinking emerged as teachers excluded the students, or what they consider ‘the problems’ from the classroom. Exclusion was found to be the ‘necessary’ response when control is prioritised in the classroom. In sum, the discourse of control is available for shaping how teachers understand and support students. Developing a relationship with students empowers teachers to see past the labels, the control discourse, and truly support students in inclusive classrooms. Finally, implications for practice are shared to improve the experience of inclusive education for both student and teacher.     

Predicting pre-service teachers’ preparedness for inclusive education: Bangladeshi pre-service teachers’ attitudes and perceived teaching-efficacy for inclusive education

This study reports on the second phase of a larger study, which investigated the preparedness of pre-service teachers to teach in inclusive classrooms in Bangladesh. Phase 1 employed two standardised scales that were used with 1623 pre-service teachers from 16 teacher education institutions to measure their attitudes and perceived teaching-efficacy for inclusive education. The findings of Phase 1 indicated that the level and length of training, along with gender, influenced both teacher attitudes and teaching-efficacy. In Phase 2, semi-structured interviews with six administrative heads of the pre-service teacher education institutions were conducted in order to better understand these findings. Outcomes of Phase 2 indicated that curriculum, teacher-related and a number of contextual variables may explain the differences in the findings of this study that were in sharp contrast to those from previous international research. Recommendations for policy and curriculum reform for pre-service teacher education are also made.     

A combined approach to strengthen children’s scientific thinking: direct instruction on scientific reasoning and training of teacher’s verbal support

Inquiry-based lessons have been demonstrated to improve children’s scientific thinking (i.e. reasoning abilities and domain-specific knowledge). Although empirical evidence shows that inquiry-based learning requires instruction, research comes from two approaches that have not been bridged yet: direct instruction of scientific reasoning and teacher training of verbal support. We investigated how these two types of instruction separately or combined strengthened children’s scientific thinking by comparing four conditions: baseline, direct instruction, verbal support, and a combined approach. Effectiveness of an inquiry-based lesson series on scientific reasoning abilities, vocabulary, and domain-specific knowledge (near and far transfer) were studied among 301 fourth graders. Results showed that both approaches strengthened different components of scientific reasoning abilities, and that a combination of instructions was most effective for scientific reasoning abilities, vocabulary, and domain-specific knowledge. Domain-specific knowledge acquisition was strengthened only when both instructions were provided. It can thus be concluded that each type of instruction has unique contributions to children’s science learning and that these instructions complement each other. Our study thus showed that inquiry-based lesson series when preceded by direct instruction of scientific reasoning and scaffolded with verbal support are most effective.     

Pre-service teachers’ perceptions of effective inquiry instruction: are effective instruction and effective inquiry instruction essentially the same?

This multiple case study examined pre-service teachers perceptions of effective post-secondary instruction. Pre-service teachers were asked to write essays describing an effective teacher of their choice. Twenty-one essays were randomly selected. Data analysis involved open coding of each essay, content analysis of each essay using Anderson and Burns’ (Research in classrooms: The study of teachers, teaching, and instruction (1st ed.). Oxford, England; New York: Pergamon Press, 1989) empirically derived dimensions of instruction, and effect size analysis of student and teacher roles. Instructional components were identified that differentiate between effective inquiry instruction and effective instruction. Effective inquiry instruction was associated with more and different teacher and student roles, more activities as part of instruction, and more student small group discussion than was effective instruction.     

Professional role and identity of Icelandic preschool teachers: effects of stakeholders’ views

In this article, we explore the reality of Icelandic preschool teachers who are, as in most other countries, predominantly female. The gendered nature of the role and the current identity adopted by preschool teachers appear to impact on their perceived status and professionalism. In this process, stakeholders in early childhood education (ECE), as well as the preschool teachers themselves, play important parts. The question that underlies the paper is: ‘How do the views of preschool teachers and stakeholders in ECE affect the preschool teachers’ professional identity?’ The data used to answer the question are from focus group research carried out with preschool teachers and stakeholders in ECE in one community in Iceland. These stakeholders, besides preschool teachers and staff within the preschools, were parents, professionals at the municipal preschool office and politicians. The theoretical perspective informing the methodology of the research was ‘symbolic interactionism’ and the concept of ‘democratic professionalism’ was used as an aspirational framework to analyse the data. The findings reveal connections between the ideology relating to the preschool teachers’ educational role, their limited leadership and the gendered views of stakeholders. At the end of the paper, implications and recommendations for preschool teachers are suggested.

Pre-service teachers’ views on inclusive education in Ghana

Pre-service teacher training has been identified as one of the key factors in the promotion of inclusive education. In this study, 200 final-year pre-service teachers from three colleges of education in Ghana were surveyed about their views and knowledge on inclusive education and special educational needs (SEN). The results showed that almost all of the participants had been introduced to the concept of inclusion during their studies. However, only one-third felt highly, or somewhat, prepared to teach children with SEN. The level of knowledge and feelings of self-efficacy were highest among those pre-service teachers who had personal experience of supporting children with SEN during their practicum. The participants tended to prefer those inclusive instructional strategies that were easiest to apply in general education classrooms. Significant differences in the outcomes were found between the three colleges studied indicating strong effects of the teacher education model applied in each college.
