Enhancing Elementary Pre-service Teachers’ Plant Processes Conceptions

Researchers examined how an inquiry-based instructional treatment emphasizing interrelated plant processes influenced 210 elementary pre-service teachers’ (PTs) conceptions of three plant processes, photosynthesis, cellular respiration, and transpiration, and the interrelated nature of these processes. The instructional treatment required PTs to predict the fate of a healthy plant in a sealed terrarium (Plant-in-a-Jar), justify their predictions, observe the plant over a 5-week period, and complete guided inquiry activities centered on one of the targeted plant processes each week. Data sources included PTs’ pre- and post-predictions with accompanying justifications, course artifacts such as weekly terrarium observations and science journal entries, and group models of the interrelated plant processes occurring within the sealed terraria. A subset of 33 volunteer PTs also completed interviews the week the Plant-in-a-Jar scenario was introduced and approximately 4 months after the instructional intervention ended. Pre- and post-predictions from all PTs as well as interview responses from the subgroup of PTs, were coded into categories based on key plant processes emphasized in the Next Generation Science Standards. Study findings revealed that PTs developed more accurate conceptions of plant processes and their interrelated nature as a result of the instructional intervention. Primary patterns of change in PTs’ plant process conceptions included development of more accurate conceptions of how water is used by plants, more accurate conceptions of photosynthesis features, and more accurate conceptions of photosynthesis and cellular respiration as transformative processes.

Pre-service Teachers’ Perceptions of Urban Schools

This study investigates pre-service teachers’ perceptions of urban schools. We asked 41 pre-service teachers, mostly white and female, to report their perceptions of four aspects of urban schools (appearance and atmosphere, resources, students, and teachers) and identify the sources of their perceptions. We analyze the data qualitatively to understand how they perceive urban schools and quantitatively to determine group trends in their perceptions. Findings reveal that their perceptions of urban schools are complex, with negative and positive impressions of selected aspects of urban schools. Implications of these findings for teacher education, in particular, urban field placements and curriculum, are explored.

Prospective Teachers’ Estimates of Adolescents’ Responses to F Scale Items

A recent review of research revealed that much of the advice given for writing multiple-choice test items is based on experience and wisdom rather than empirical research. The present study involved the testing of two common item-writing rules: (1) the phrasing of the stem in the form of a question versus a partial sentence and (2) the use of the inclusive “none of the above” option instead of a specific content option. Limited empirical research suggests that using the partial sentence format and the inclusive “none of these” option may lead to undesirable item and test characteristics, whereas textbook authors essentially are divided on the opinions about the validity of each rule. Results of this experimental study offer no evidence to support the use of either type of stem and limited evidence to caution against the option “none of the above.”     

Using Student Video Cases to Assess Pre-service Elementary Teachers’ Engineering Teaching Responsiveness

Our study addresses the need for new approaches to prepare novice elementary teachers to teach both science and engineering, and for new tools to measure how well those approaches are working. This in particular would inform the teacher educators of the extent to which novice teachers are developing expertise in facilitating their students’ engineering design work. One important dimension to measure is novice teachers’ abilities to notice the substance of student thinking and to respond in productive ways. This teacher noticing is particularly important in science and engineering education, where students’ initial, idiosyncratic ideas and practices influence the likelihood that particular instructional strategies will help them learn. This paper describes evidence of validity and reliability for the Video Case Diagnosis (VCD) task, a new instrument for measuring pre-service elementary teachers’ engineering teaching responsiveness. To complete the VCD, participants view a 6-min video episode of children solving an engineering design problem, describe in writing what they notice about the students’ science ideas and engineering practices, and propose how a teacher could productively respond to the students. The rubric for scoring VCD responses allowed two independent scorers to achieve inter-rater reliability. Content analysis of the video episode, systematic review of literature on science and engineering practices, and solicitation of external expert educator responses establish content validity for VCD. Field test results with three different participant groups who have different levels of engineering education experience offer evidence of construct validity.     

Teachers’ Responses to the Ecosystemic Approach to Changing Chronic Problem Behaviour in Schools

This paper discusses the responses of a group of thirty-three primary and two secondary teachers to a series of sessions in which the ecosystemic approach to changing chronic problem behaviour in schools was explained and then tried out in practice. Three case examples are presented, as well as related discussions, which illustrate the approach. This study follows on from the work reported in Pastoral Care, December 1998.     

Pre-service Mathematics Teachers’ Noticing Skills and Scaffolding Practices

A 14-week course program was designed to investigate pre-service teachers’ noticing skills and scaffolding practices. Six pre-service teachers were matched with a pair of sixth grade students to observe and scaffold students’ mathematical understanding while they were working on the given tasks. Data was collected through pre-service teachers’ own recorded videos of implementation of tasks, their written reflections about the implementations, videos of group reflections before and after the implementations, and students’ written work. The analysis of data revealed that pre-service teachers mostly noticed students’ errors and strategies during their interactions with students, they attended important instances about students’ thinking and justified their reasoning for their comments in their written reflections. However, while interacting with students, they usually used low level scaffolding practices such as asking for clarification, explanation, and justification rather than attempting to elicit students’ thinking and improve their understanding.

Changes in Pre-service Science Teachers’ Understandings After Being Involved in Explicit Nature of Science and Socioscientific Argumentation Processes

The study explored the changes in pre-service science teachers’ understanding of the nature of science and their opinions about the nature of science, science teaching and argumentation after their participation in explicit nature of science (NOS) and socioscientific argumentation processes. The participants were 56 third-grade pre-service science teachers studying in a state university in Turkey. The treatment group comprised 27 participants, and there were 29 participants in the comparison group. The comparison group participants were involved in a student-centred science-teaching process, and the participants of the treatment group were involved in explicit NOS and socioscientific argumentation processes. In the study, which lasted a total of 11 weeks, a NOS-as-argumentation questionnaire was administered to all the participants to determine their understanding of NOS at the beginning and end of the data collection process, and six random participants of the treatment group participated in semi-structured interview questions in order to further understand their views regarding NOS, science teaching and argumentation. Qualitative and quantitative data analysis revealed that the explicit NOS and socioscientific argumentation processes had a significant effect on pre-service science teachers’ NOS understandings. Furthermore, NOS, argumentation and science teaching views of the participants in the treatment group showed a positive change. The results of this study are discussed in light of the related literature, and suggestions are made within the context of contribution to science-teaching literature, improvement of education quality and education of pre-service teachers.

Expansion of Biology Teachers’ Pedagogical Content Knowledge (PCK) During a Long-Term Professional Development Program

Experienced teachers possess a unique teaching knowledge comprised of an inter-related set of knowledge and beliefs that gives direction and justification to a teacher’s actions. This study examined the expansion of two components of pedagogical content knowledge (PCK) of three in-service teachers in the course of a professional development program aimed at designing new teaching and learning materials suggested by the teachers themselves. The research presents an enlargement of previous PCK representations by focusing on a detailed representation of two main PCK domains: teaching and learning, including ten PCK components that emerged in the course of data analysis. This representation enabled revealing the unique PCK held by each teacher and to characterize the expansion of the two components of the participating teachers’ PCK during the long-term professional development program. Retention of major parts of the expanded PCK a year after termination of the program implies that designing and implementing new teaching and learning materials based on the teachers’ experiences, needs, and knowledge in a workshop format accompanied by biology and science education courses might provide a powerful means for PCK expansion. We recommend that designers of professional development programs be aware of the unique PCK held by each teacher in order to promote meaningful professional development of each teacher. Moreover, the PCK representations that were identified in the course of this study enabled clarifying the “orientation toward teaching science” category of PCK which appears to be unclear in current literature.     

The Role of Immigration Background,Intergroup Processes,and Social-Cognitive Skills in Bystanders’ Responses to Bias-Based Bullying Toward Immigrants During Adolescence

This study examined how intergroup processes and social-cognitive factors shape bystander responses to bias-based and general bullying. Participants included sixth and ninth graders (N = 179, M = 13.23) who evaluated how likely they would be to intervene if they observed bullying of immigrant-origin and nonimmigrant-origin peers. Adolescents’ grade, intergroup attitudes, and social-cognitive abilities were evaluated as predictors of bystander responses. Nonimmigrant-origin adolescents reported that they expect they would be less likely to intervene when the victim is an immigrant-origin peer. Furthermore, participants with more intergroup contact and higher theory of mind were more likely to expect they would intervene in response to bias-based bullying. Findings have important implications for understanding factors that inform antibullying interventions that aim to tackle bias-based bullying against immigrants.     

Consolidating Pre-service Physics Teachers’ Subject Matter Knowledge Using Didactical Reconstructions

In the Department of Physics, University of Helsinki, there are advanced physics courses designed for the needs of pre-service physics teachers. The starting point is that after introductory and intermediate physics courses, pre-service physics teachers know laws and definitions but the knowledge is quite fragmented and does not form coherent wholes. Graphical tools called didactical reconstructions were developed to help pre-service physics teachers to consolidate their physics knowledge. The idea behind the reconstructions is that “new” physics knowledge is always constructed based on previous knowledge (quantities, laws, theory). This means that every new concept is connected to previous concepts when it is formed; this is captured in the didactical reconstruction of processes. Then, when the knowledge is further constructed, the formed concept will be connected to other new concepts. This approach leads to the didactical reconstruction of structure: networks of quantities and laws, where the experiments and models construct the connections between quantities and laws. Here an overview and summary of the educational approach based on the didactical reconstruction is given for the first time. The results of the previously reported case studies show that the didactical reconstructions help students to connect the knowledge pieces into meaningful and more coherent wholes. These didactical reconstructions are now an integral part of our pre-service physics teacher education.     

Epistemological Predictors of “Self Efficacy on Learning Biology” and “Test Anxiety Related to Evaluation of Learning on Biology” for Pre-service Elementary Teachers

The degree to which pre-service teachers learn biology is related to both motivational factors of self-regulation and factors regarding epistemological beliefs. At the same time, self-regulation and epistemological beliefs are also associated with one another. Based on this relationship, the purpose of this study was to investigate the relationship between components of epistemological beliefs and self-refulation (self-efficacy and test-anxiety) on learning biology. The study was conducted with 411 pre-service elementary and pre-service elementary science teachers by using a predictive research approach. Collected data was analyzed by the multiple linear regression technique. The results showed that only the belief about “existence of one truth” was a significant predictor of test anxiety while there was no epistemological predictor of self-efficacy. Conclusions and implications of the study will be discussed.     

Fostering Pre-service Teachers’ Self-Determined Environmental Motivation Through Green Chemistry Experiments

The global environmental crisis intensifies particularly in developing nations. Environmental educators have begun to understand that changing the environmental impact requires not only changes in pro-environmental knowledge and attitudes but also in associated, self-determined motivation. This study was designed to test the hypothesis that a green chemistry curriculum changes Malaysian pre-service teachers?? environmental motivation. Two comparable groups of pre-service teachers participated in this study. The students in the experimental group (N?=?140) did green chemistry experiments whereas the control group (N?=?123) did equivalent experiments in a traditional manner. Posttest results indicate that there is significant difference between both the groups for intrinsic motivation, integration, identification, and introjections scales and no differences for external regulation and amotivation scales. The qualitative analysis of interview data suggests that the changes are predominantly due to the personal satisfaction that participants derived from engaging in pro-environmental behavior.     

Confronting Invisibility: Early Childhood Pre-service Teachers’ Beliefs Toward Homeless Children

Children make up half of the homeless population in the US, and of those, almost 50 percent are under age six. Homeless children face many different challenges in school. These children and their families have been invisible in school due to the indifference and stereotypes about them. This article focuses on early childhood pre-service teachers’ beliefs over the course of one semester at a private university in the United States. The pre-service teachers explored their own perceptions about homeless children through urban community-based field experiences. The pre-service teachers regularly worked with children in homeless shelter learning centers throughout the semester. The data revealed that the pre-service teachers had fears about interacting with the unfamiliar setting, as well as deficit perspectives about homeless children. However, while they were engaged in the community-based experiences, they started to re-examine their deficit views about young homeless children and their families, acquire more accurate information on their complex situations, and positively developed their professional perspectives on these children. This study suggests that raising awareness about homeless children and their families should be a part of both professional development in schools and early childhood teacher education programs     

The Nature of Pre-service Science Teachers’ Argumentation in Inquiry-oriented Laboratory Context

The aim of this study was to investigate the kinds of argumentation schemes generated by pre-service elementary science teachers (PSTs) as they perform inquiry-oriented laboratory tasks, and to explore how argumentation schemes vary by task as well as by experimentation and discussion sessions. The model of argumentative and scienti?c inquiry was used as a design framework in the present study. According to the model, the inquiry of scientific topics was employed by groups of participants through experimentation and critical discussion sessions. The participants of the study were 35 PSTs, who teach middle school science to sixth through eighth grade students after graduation. The data were collected through video- and audio-recordings of the discussions made by PSTs in six inquiry-oriented laboratory sessions. For the analysis of data, pre-determined argumentation schemes by Walton were employed. The results illustrated that PSTs applied varied premises rather than only observations or reliable sources to ground their claims or to argue for a case or an action. It is also worthy of notice that the construction and evaluation of scientific knowledge claims resulted in different numbers and kinds of arguments. Results of this study suggest that designing inquiry-oriented laboratory environments, which are enriched with critical discussion, provides discourse opportunities that can support argumentation. Moreover, PSTs can be encouraged to support and promote argumentation in their future science classrooms if they engage in argumentation integrated instructional strategies.     

Preservice Biology Teachers’ Conceptions About the Tentative Nature of Theories and Models in Biology

In research on the nature of science, there is a need to investigate the role and status of different scientific knowledge forms. Theories and models are two of the most important knowledge forms within biology and are the focus of this study. During interviews, preservice biology teachers (N = 10) were asked about their understanding of theories and models. They were requested to give reasons why they see theories and models as either tentative or certain constructs. Their conceptions were then compared to philosophers’ positions (e.g., Popper, Giere). A category system was developed from the qualitative content analysis of the interviews. These categories include 16 conceptions for theories (n _tentative = 11; n _certain  = 5) and 18 conceptions for models (n _tentative = 10; n _certain = 8). The analysis of the interviews showed that the preservice teachers gave reasons for the tentativeness or certainty of theories and models either due to their understanding of the terms or due to their understanding of the generation or evaluation of theories and models. Therefore, a variety of different terminology, from different sources, should be used in learning-teaching situations. Additionally, an understanding of which processes lead to the generation, evaluation, and refinement or rejection of theories and models should be discussed with preservice teachers. Within philosophy of science, there has been a shift from theories to models. This should be transferred to educational contexts by firstly highlighting the role of models and also their connections to theories.     

Elementary School Teachers’ Use of Technology During Mathematics Teaching

Various educational technologies have been advanced as potential vehicles to transform teaching and learning. Still, research studies have documented that primary school teachers struggle to integrate technology in meaningful ways. This article presents the findings of a year-long study in which the author frequently observed three primary school teachers’ enactments of technology into their mathematics teaching. Each teacher was observed between 25 and 30 times during the school year. The types of technologies used as well as the types of mathematical tasks and problems that participants posed while teaching with technology were inductively analyzed. Inductive qualitative analyses indicated that participants’ technology use focused on presentation technologies such as the document camera or interactive whiteboard more than computer-based technologies or interactive activities. Further, teachers varied widely in their enacted pedagogies while integrating technology, and two participants demonstrated more frequent enactments of learner-centered pedagogies toward the end of the school year. Implications for researching teachers’ use of technology in the future are also shared.
