Development and Application of a Three‐Tier Diagnostic Test to Assess Secondary Students’ Understanding of Waves

This study focused on the development and application of a three‐tier multiple‐choice diagnostic test (or three‐tier test) on the nature and propagation of waves. A question in a three‐tier test comprises the content tier, which measures content knowledge; the reason tier, which measures explanatory knowledge; and the confidence tier, which measures the strength of conceptual understanding of the respondents. This paper presents results based on the responses of 243 Grade 10 students after they were formally instructed on the topic. The vast majority of the respondents showed an inadequate grasp of concepts about waves. Eleven alternative conceptions (ACs), which were expressed with confidence by more than 10% of the students, were identified; four of these ACs were expressed with high confidence.     

Development and Application of a Two-Tier Diagnostic Test for High School Students’ Understanding of Flowering Plant Growth and Development

This study involved the development and application of a two-tier diagnostic test measuring students understanding of flowering plant growth and development. The instrument development procedure had three general steps: defining the content boundaries of the test, collecting information on students misconceptions, and instrument development. Misconception data were collected from interviews and multiple-choice questions with open response answers. The data were used to develop 13 two-tier multiple-choice items. The conceptual knowledge examined was flowering plant life cycles, reproduction, precondition of germination, plant nutrition, and mechanism for growth and development. The diagnostic instrument was administered to 477 high school students. The correlation coefficient of test-retest was 0.75. Difficulty indices ranged from 0.24 to 0.82, and discrimination indices ranged from 0.32 to 0.65. Results of the Flowering Plant Growth and Development Diagnostic Test suggested that students did not acquire a satisfactory understanding of plant growth and development concepts. Nineteen misconceptions were identified through analysis of the items that could inform biology instruction and resource.     

A Three-Tier Diagnostic Test to Assess Pre-Service Teachers’ Misconceptions about Global Warming,Greenhouse Effect,Ozone Layer Depletion,and Acid Rain

This study describes the development and validation of a three-tier multiple-choice diagnostic test, the atmosphere-related environmental problems diagnostic test (AREPDiT), to reveal common misconceptions of global warming (GW), greenhouse effect (GE), ozone layer depletion (OLD), and acid rain (AR). The development of a two-tier diagnostic test procedure as described by Treagust constitutes the framework for this study. To differentiate a lack of knowledge from a misconception, a certainty response index is added as a third tier to each item. Based on propositional knowledge statements, related literature, and the identified misconceptions gathered initially from 157 pre-service teachers, the AREPDiT was constructed and administered to 256 pre-service teachers. The Cronbach alpha reliability coefficient of the pre-service teachers’ scores was estimated to be 0.74. Content and face validations were established by senior experts. A moderate positive correlation between the participants’ both-tiers scores and their certainty scores indicated evidence for construct validity. Therefore, the AREPDiT is a reliable and valid instrument not only to identify pre-service teachers’ misconceptions about GW, GE, OLD, and AR but also to differentiate these misconceptions from lack of knowledge. The results also reveal that a majority of the respondents demonstrated limited understandings about atmosphere-related environmental problems and held six common misconceptions. Future studies could test the AREPDiT as a tool for assessing the misconceptions held by pre-service teachers from different programs as well as in-service teachers and high school students.     

Reliability and Preliminary Use of a Rubric to Assess Pre-Kindergarten Teachers’ Video Uses

The presence and use of new technologies in early childhood settings are rapidly increasing. One technology tool used in early childhood settings is monthly DVD classroom newsletters, yet there is a lack of assessments to support pre-kindergarten teachers’ uses of such DVD newsletter technology—in general and in specific. The present study helps to fill this gap by developing and testing a revised rubric to evaluate the quality of monthly DVD classroom newsletters. Results indicate that the revised Monthly DVD Classroom Newsletter-Rubric exhibited good overall reliability. We suggest that the use of a rubric to assess pre-kindergarten teacher-created monthly DVD classroom newsletters supports teachers’ decision making about technology uses and professional development.     

Development and Validation of a Scale to Assess Students’ Attitude towards Animal Welfare

This work presents the development of a scale of attitudes of secondary-school and university students towards animal welfare. A questionnaire was drawn up following a Likert-type scale attitude assessment model. Four components or factors, which globally measure animal welfare, are proposed to define the object of the attitude. The components are animal abuse for pleasure or due to ignorance (C1), leisure with animals (C2), farm animals (C3) and animal abandonment (C4). The final version of the questionnaire contains 29 items that are evenly distributed among the four components indicated, guaranteeing that each component is one-dimensional. A sample of 329 students was used to validate the scale. These students were aged between 11 and 25, and were from secondary schools in Aragon and the University in Zaragoza (Aragon's main and largest city, located in NE Spain). The scale shows good internal reliability, with a Cronbach's alpha value of 0.74. The questionnaire was later given to 1,007 students of similar levels and ages to the sample used in the validation, the results of which are presented in this study. The most relevant results show significant differences in gender and level of education in some of the components of the scale, observing that women and university students rate animal welfare more highly.     

Evaluation of Three Primary Teachers’ Approaches to Teaching Scientific Concepts in Persuasive Ways

The research set out in this paper seeks to develop pedagogical knowledge regarding how persuasive teaching approaches can be developed in primary science classrooms. To achieve this, the paper examines three case studies in which the teachers have been charged to develop and implement teaching strategies designed to persuade their children of the usefulness and validity of target scientific concepts. The analysis probes the teachers’ choice of contexts and patterns of discourse using criteria drawn from the socio‐cultural literature. Outcomes of the study exemplify how the teachers’ choices of learning contexts fail to emphasise the functionality of the target concepts, and as a consequence scant rewards are provided for the children to participate actively in conceptually rich discourse. The final part of the paper explores how the development of what the author calls theme‐specific plots could be used to help teachers to stage teaching and learning performances that emphasise the functionality of specific explanatory models.     

Primary School Teachers’ Understanding of Science Process Skills in Relation to Their Teaching Qualifications and Teaching Experience

This study investigated the understanding of science process skills (SPS) of 329 science teachers from 52 primary schools selected by random sampling. The understanding of SPS was measured in terms of conceptual and operational aspects of SPS using an instrument called the Science Process Skills Questionnaire (SPSQ) with a Cronbach’s alpha reliability of 0.88. The findings showed that the teachers’ conceptual understanding of SPS was much weaker than their practical application of SPS. The teachers’ understanding of SPS differed by their teaching qualifications but not so much by their teaching experience. Emphasis needs to be given to both conceptual and operational understanding of SPS during pre-service and in-service teacher education to enable science teachers to use the skills and implement inquiry-based lessons in schools.     

Teachers’ Understanding and Operationalisation of ‘Science Capital’

Across the globe, governments, industry and educationalists are in agreement that more needs to be done to increase and broaden participation in post-16 science. Schools, as well as teachers, are seen as key in this effort. Previous research has found that engagement with science, inclination to study science and understanding of the value of science strongly relates to a student's science capital. This paper reports on findings from the pilot year of a one-year professional development (PD) programme designed to work with secondary-school teachers to build students’ science capital. The PD programme introduced teachers to the nature and importance of science capital and thereafter supported them to develop ways of implementing science capital-building pedagogy in their practice. The data comprise interviews with the participating teachers (n?=?10), observations of classroom practices and analyses of the teachers’ accounts of their practice. Our findings suggest that teachers found the concept of science capital to be compelling and to resonate with their own intuitive understandings and experiences. However, the ways in which the concept was operationalised in terms of the implementation of pedagogical practices varied. The difficulties inherent in the operationalisation are examined and recommendations for future work with teachers around the concept of science capital are developed.     

Physical Education Pre-service Teachers’ Understanding,Application, and Development of Critical Thinking

To better prepare physical education (PE) teachers, this study explored a group of pre-service teachers’ understanding, application, and development of critical thinking (CT) in a capstone methods course. Participants were 12 pre-service teachers from a PE teacher education (PETE) program at a large university in the southwestern United States. Data were collected through focus group interviews and post-lab assignments and were analyzed via content analysis. Findings showed that the PE pre-service teachers could define CT and recognize its importance to teaching and learning. Together with field-based teaching practices, course written assignments such as the encyclopedia article, curriculum project, lesson plans, and post assignments were identified as contributors to CT development. At the end of the semester, the PE pre-service teachers demonstrated an improvement in CT across three levels. Based on our findings, we recommend the integration of CT instruction into PETE programs.     

A Survey of Primary School Teachers’ Understanding and Implementation of Moral Education in Trinidad and Tobago 1

Abstract

Results from a survey of teachers’ understanding and implementation of moral education in primary schools in Trinidad and Tobago are presented here, against consideration of the role of moral education in schooling. The paper discusses the range of moral curricula available for the implementation of moral education in schools and constraints on implementation in the classroom. It also compares the need for and applicability of moral education programmes in developing and developed countries. In Trinidad and Tobago, noted for its population and religious mix, the role of moral education has been given importance from the highest levels at the Ministry of Education and elsewhere in government. The survey of a representative sample of teachers in primary schools throughout the country showed that they largely felt themselves responsible for introducing moral education to their pupils, although they rarely drew upon any specific curriculum. They tended to take a ‘virtues’ approach in their teaching of moral education, and were generally satisfied with the results of their efforts. There were few differences between understanding and implementation of moral education that could be attributed to age, sex, experience or responsibilities of the teacher, or the age of the pupils. These results are not just characteristic of a developing country as they mirror earlier findings in England and elsewhere.

     

How to Assess and Categorize Teachers’ Views of Science? Two Methodological Issues

Research in Science Education - This paper addresses two methodological issues related to the assessment of teachers’ views of science. The first concerns the distinction between the...     

Development of Preservice Teachers’ Ability to Critique and Adapt Inquiry-based Instructional Materials

Current standards emphasize student engagement with inquiry practices. However, implementing inquiry instruction is a formidable challenge for teachers as they often lack models for using and adapting inquiry-based instructional materials. Teacher education programs can provide scaffolded contexts for developing teachers’ ability to critique, adapt, and design inquiry-based materials. We describe a qualitative study of 17 preservice teachers enrolled in two consecutive science methods courses. The study characterizes the development of preservice teachers’ ability to critique and revise instructional materials. Our findings suggest that teachers improved in their ability to critique lesson plans and to suggest revisions that would make them more inquiry oriented. In particular, the teachers’ critiques and revisions increased in sophistication after engaging in instructional design activities during the second methods course.     

Do Students Know What They Know and What They Don’t Know? Using a Four-Tier Diagnostic Test to Assess the Nature of Students’ Alternative Conceptions

This study reports on the development and application of a four-tier multiple-choice (4TMC) diagnostic instrument, which has not been reported in the literature. It is an enhanced version of the two-tier multiple-choice (2TMC) test. As in 2TMC tests, its answer and reason tiers measure students’ content knowledge and explanatory knowledge, respectively. The two additional tiers measure the level of confidence of students in the correctness of their chosen options for the answer and reason tiers respectively. The 4TMC diagnostic test focused on the properties and propagation of mechanical waves. It was administered to 598 upper secondary students after they were formally instructed on the foregoing topics. The vast majority of the respondents were found to have an inadequate grasp of the topics tested. Mean scores and mean confidence associated with the answer tier was higher than those associated with the reason tier. The students tended to be poorly discriminating between what they know and what they do not know. Familiarity with the topic tested was associated with greater percentage of students giving correct answers, higher confidence, and better discrimination quotient. Nine genuine alternative conceptions (which were expressed with moderate levels of confidence by students) were identified.     

A Preliminary Evaluation of REACH: Training Early Childhood Teachers to Support Children’s Social and Emotional Development

This paper describes the development, implementation and preliminary evaluation of the Reaching Educators and Children (REACH) program, a training and coaching intervention designed to increase the capacity of early childhood teachers to support children’s social and emotional development. We evaluated REACH with 139 teachers of toddler and preschool classrooms. Teacher attendance and survey results suggest that teachers were highly satisfied with the training and materials. Data from classroom observation scales conducted pre- and post-REACH implementation suggest significant improvements in the sensitivity of teachers’ interactions with children in the classroom, and increased teacher use of targeted social and emotional supports (such as teaching children to resolve conflicts). Further, data from observations of children’s classroom behavior suggest increases in children’s prosocial behaviors and small but significant decreases in verbal aggression. These findings provide preliminary evidence that the REACH program may be effective in building teachers’ capacity to support social–emotional development of young children, and point to the need for additional research.     

Undergraduate Social Work Students’ Perceptions of a Team-Based Learning Approach to Exploring Adult Development

ABSTRACT

Social work educators are challenged to adopt innovative instructional methods and pedagogies to prepare students to meet the contemporary needs of diverse client populations. A team-based learning (TBL) approach is a pedagogical strategy that utilizes cooperative and collaborative learning principles to inspire academic, professional, and interpersonal growth for students. This study explores perspectives of 93 undergraduate social work students regarding the benefits and challenges of using a TBL approach to research adult development. Despite identifying several benefits of this method, including in-depth learning and enhanced relationships, students also experienced significant challenges to working in teams.     

Determination and Evaluation of the Science Teacher Candidates’ Misconceptions About Density by Using Four-Tier Diagnostic Test

This study has two aims. The first one is to reveal the science teacher candidates’ misconceptions about the density by using a four-tier diagnostic test, and the second one is to determine to what extent science teacher candidates have scientific knowledge, lack of knowledge, and misconceptions about the density. In order to achieve these aims, a four-tier density diagnostic test was developed with the KR-20 reliability coefficient of 0.753 based on the correct answers, and the KR-20 reliability coefficient of 0.528 based on the misconceptions. To determine the misconceptions about the density with the developed test, data were collected from a total of 470 science teacher candidates from seven different universities in Turkey. With the developed four-tier diagnostic test, 48 different misconceptions were revealed. The results of the research showed that about one fourth of science teacher candidates had a misconception about the density and that the ratio of six of the resulting misconceptions was over 10%. It may be suggested that this study conducted on science teacher candidates should also be conducted on middle and high school students and experimental studies should be carried out to eliminate the misconceptions that emerged in this study.

     

Teachers’ Sickness Absence in Primary Schools,School Climate and Teachers’ Sense of Efficacy

Training programmes may compromise governors' ability to offer an authentic lay’ input. The article reports the views of governors interviewed about their perceptions of the need for a degree of expert status. It is tentatively suggested that training courses may be contributing both to a sense of inadequacy and to the tendency to become ‘incorporated’ into an institutionalised role. Some models of governor training are considered in relation to their possible effects.
