Preservice Elementary Teachers’ Beliefs About Science Teaching

In this study, a Beliefs About Teaching (BAT) scale was created to examine preservice elementary science teachers’ self-reported comfort level with both traditional and reform-based teaching methods, assessment techniques, classroom management techniques, and science content. Participants included 166 preservice teachers from three different US universities. Analyses revealed significant correlations among participants’ confidence level with assessment techniques, classroom management, teaching methods, and science content and number of science methods and science content courses taken. A significant difference was observed among the students enrolled at each university. Overall, study participants felt more comfortable teaching biology concepts than teaching chemistry concepts, physics concepts, or both.     

Integrated Science Students’ Assessment of their Teachers for Characteristics of Effective Science Teaching

This study explored views held by pre-service and in-service science teachers regarding the nature of science and technology particularly: (a) the characteristics of science and technology; (b) the aim of science and scientific research; (c) the characteristics of scientific knowledge and scientific theories; and (d) the relationship between science and technology. The views held by science teachers at pre-service and in-service levels were assessed using a questionnaire. The findings revealed that generally science teachers at both pre-service and in-service levels showed similar views in relation to the nature of science and technology. While the participants displayed mix views regarding science as content oriented or process oriented, technology was viewed as an application of science. Implications of these views for classroom teaching and learning are presented.     

Effects of 3D Printing Project-based Learning on Preservice Elementary Teachers’ Science Attitudes,Science Content Knowledge,and Anxiety About Teaching Science

3D printing technology is a powerful educational tool that can promote integrative STEM education by connecting engineering, technology, and applications of science concepts. Yet, research on the integration of 3D printing technology in formal educational contexts is extremely limited. This study engaged preservice elementary teachers (N?=?42) in a 3D Printing Science Project that modeled a science experiment in the elementary classroom on why things float or sink using 3D printed boats. The goal was to explore how collaborative 3D printing inquiry-based learning experiences affected preservice teachers’ science teaching self-efficacy beliefs, anxiety toward teaching science, interest in science, perceived competence in K-3 technology and engineering science standards, and science content knowledge. The 3D printing project intervention significantly decreased participants’ science teaching anxiety and improved their science teaching efficacy, science interest, and perceived competence in K-3 technological and engineering design science standards. Moreover, an analysis of students’ project reflections and boat designs provided an insight into their collaborative 3D modeling design experiences. The study makes a contribution to the scarce body of knowledge on how teacher preparation programs can utilize 3D printing technology as a means of preparing prospective teachers to implement the recently adopted engineering and technology standards in K-12 science education.     

The Integration of Preservice Teachers’ Naive and Informed Beliefs about Learning and Teaching

Preservice teacher education students are likely to have acquired naive beliefs about learning and teaching, that need to be integrated with theoretically informed beliefs, if they are to function effectively in classrooms. This study explored the nature of such integration using a sample of Graduate Diploma in Education students engaged in an educational psychology subject which was designed to help students develop constructivist beliefs and approaches to learning. Investigation of students’ journal entries, written statements, and stimulated recall interviews related to videotaped practice teaching sessions, revealed that students were able to integrate prior beliefs with the theoretical content of the course, enabling them to describe, and in some cases, evidence informed conditional knowledge.     

Preservice Elementary Teachers’ Science Self-Efficacy Beliefs and Science Content Knowledge

Self-efficacy beliefs that relate to teachers’ motivation and performance have been an important area of concern for preservice teacher education. Research suggests high-quality science coursework has the potential to shape preservice teachers’ science self-efficacy beliefs. However, there are few studies examining the relationship between science self-efficacy beliefs and science content knowledge. The purpose of this mixed methods study is to investigate changes in preservice teachers’ science self-efficacy beliefs and science content knowledge and the relationship between the two variables as they co-evolve in a specialized science content course. Results from pre- and post-course administrations of the Science Teaching Efficacy Belief Instrument-B (Bleicher, 2004) and a physical science concept test along with semi-structured interviews, classroom observations and artifacts served as data sources for the study. The 18 participants belonged to three groups representing low, medium and high initial levels of self-efficacy beliefs. A repeated measures multivariate analysis of variance design was used to test the significance of differences between the pre- and post-surveys across time. Results indicated statistically significant gains in participants’ science self-efficacy beliefs and science conceptual understandings. Additionally, a positive moderate relationship between gains in science conceptual understandings and gains in personal science teaching efficacy beliefs was found. Qualitative analysis of the participants’ responses indicated positive shifts in their science teacher self-image and they credited their experiences in the course as sources of new levels of confidence to teach science. The study includes implications for preservice teacher education programs, science teacher education, and research.     

Effects of Problem-Based Learning on University Students’ Epistemological Beliefs About Physics and Physics Learning and Conceptual Understanding of Newtonian Mechanics

This study investigated the effects of problem-based learning on students’ beliefs about physics and physics learning and conceptual understanding of Newtonian mechanics. The study further examines the relationship between students’ beliefs about physics and their conceptual understanding of mechanics concepts. Participants were 124 Turkish university students (PBL = 55, traditional = 69) enrolled in a calculus-based introductory physics class. Students’ beliefs about physics and physics learning and their physics conceptual understanding were measured with the Colorado Learning Attitudes about Science Survey (CLASS) and the Force Concept Inventory (FCI), respectively. Repeated measures analysis of variance of how PBL influence beliefs and conceptual understanding were performed. The PBL group showed significantly higher conceptual learning gains in FCI than the traditional group. PBL approach showed no influence on students’ beliefs about physics; both groups displayed similar beliefs. A significant positive correlation was found between beliefs and conceptual understanding. Students with more expert-like beliefs at the beginning of the semester were more likely to obtain higher conceptual understanding scores at the end of the semester. Suggestions are presented regarding the implementation of the PBL approach.     

Teaching Science Inquiry in Urban Contexts: The Role of Elementary Preservice Teachers’ Beliefs

This paper reports on a study of elementary preservice teachers’ inquiry-based practices, their efficacy beliefs, and the role beliefs had on two preservice teachers’ practices in urban classrooms. Results show inquiry-based practices can be cultivated through field-based experiences and preservice teachers’ efficacy beliefs, as it relates to practice in urban settings, are malleable. Specifically, personal efficacy beliefs about teaching science improved or were sustained for one cohort of preservice teachers. However, beliefs about students’ ability to learn science, that is outcome beliefs, were less stable. The results of two case studies show that science content knowledge was a factor in preservice teachers’ inquiry-based practices. However, why preservice teachers’ beliefs about student learning declined is less clear. More research is needed, along with follow-up data on teacher induction, to learn how preservice teachers’ beliefs impact urban students’ science education.     

The Influence of Metacognitive Training on Preservice Elementary Teachers’ Conceptions of Nature of Science

This study assessed the influence of training in, and use of, metacognitive strategies on the development of prospective elementary teachers’ views of nature of science (NOS). Participants were 49 students (92% female) enrolled in two sections of an elementary science methods course. The sections were randomly assigned to an intervention group and a comparison group. Students in both groups were engaged with explicit‐reflective NOS instruction, which focused on the empirical, tentative, theory‐driven, inferential, and creative NOS. Additionally, students in the intervention group received instruction in, and used, three metacognitive strategies during their engagement with thinking about NOS. The Views of Nature of Science Questionnaire—Form C and the Metacognitive Awareness Inventory were respectively used to assess participants’ views of NOS and metacognitive awareness at the beginning and conclusion of the study. Data analyses indicated that significantly more students in the intervention group explicated more informed views of the target aspects of NOS. Moreover, these substantial changes were coupled with significantly increased Metacognitive Awareness Inventory scores for the intervention group participants. The results point to a relationship between improved metacognitive awareness and the development of informed understandings of NOS.

Exploring the Development of Preservice Science Teachers’ Views on the Nature of Science in Inquiry-Based Laboratory Instruction

The purpose of this study was to explore the effect of the inquiry-based and explicit–reflective laboratory instruction on preservice science teachers’ (PSTs) conceptions of the nature of science (NOS) aspects. This study was carried out during the Laboratory Application in Science II course. All 52 preservice elementary science teachers enrolled in the course consented to participate in the study; 37 were female and 15 were male, with a mean age of 22.8 years. All had the same science major background, and all of them were juniors. The course provided meaningful and practical inquiry-based experiences, as well as explicit and reflective instruction about NOS. Each week, a specific NOS aspect was targeted related to the inquiry-based laboratory investigation. The design of the study was qualitative and exploratory in nature. At the beginning of the study, the Views of Nature of Science Questionnaire Version B open-ended questionnaire was applied to explore PSTs’ NOS views. At the end of the semester, the same questionnaire was conducted to determine the impact of the explicit–reflective and inquiry-based laboratory instruction. The results showed that many PSTs improved their views of NOS in each element, although to different degrees.     

Effect of Robotics on Elementary Preservice Teachers’ Self-Efficacy,Science Learning,and Computational Thinking

The current impetus for increasing STEM in K-12 education calls for an examination of how preservice teachers are being prepared to teach STEM. This paper reports on a study that examined elementary preservice teachers’ (n = 21) self-efficacy, understanding of science concepts, and computational thinking as they engaged with robotics in a science methods course. Data collection methods included pretests and posttests on science content, prequestionnaires and postquestionnaires for interest and self-efficacy, and four programming assignments. Statistical results showed that preservice teachers’ interest and self-efficacy with robotics increased. There was a statistically significant difference between preknowledge and postknowledge scores, and preservice teachers did show gains in learning how to write algorithms and debug programs over repeated programming tasks. The findings suggest that the robotics activity was an effective instructional strategy to enhance interest in robotics, increase self-efficacy to teach with robotics, develop understandings of science concepts, and promote the development of computational thinking skills. Study findings contribute quantitative evidence to the STEM literature on how robotics develops preservice teachers’ self-efficacy, science knowledge, and computational thinking skills in higher education science classroom contexts.     

Preservice Science Teachers’ Epistemological Beliefs and Informal Reasoning Regarding Socioscientific Issues

This study investigated preservice elementary science teachers’ (PSTs) informal reasoning regarding socioscientific issues (SSI), their epistemological beliefs, and the relationship between informal reasoning and epistemological beliefs. From several SSIs, nuclear power usage was selected for this study. A total of 647 Turkish PSTs enrolled in three large universities in Turkey completed the open-ended questionnaire, which assessed the participants’ informal reasoning about the target SSI, and Schommer’s (1990) Epistemological Questionnaire. The participants’ epistemological beliefs were assessed quantitatively and their informal reasoning was assessed both qualitatively and quantitatively. The findings revealed that PSTs preferred to generate evidence-based arguments rather than intuitive-based arguments; however, they failed to generate quality evidence and present different types of evidence to support their claims. Furthermore, among the reasoning quality indicators, PSTs mostly generated supportive argument construction. Regarding the use of reasoning modes, types of risk arguments and political-oriented arguments emerged as the new reasoning modes. The study demonstrated that the PSTs had different epistemological beliefs in terms of innate ability, omniscient authority, certain knowledge, and quick learning. Correlational analyses revealed that there was a strong negative correlation between the PSTs’ certain knowledge and counterargument construction, and there were negative correlations between the PSTs’ innate ability, certain knowledge, and quick learning dimensions of epistemological beliefs and their total argument construction. This study has implications for both science teacher education and the practice of science education. For example, PST teacher education programs should give sufficient importance to training teachers that are skillful and knowledgeable regarding SSIs. To achieve this, specific SSI-related courses should form part of science teacher education programs.     

The Research of Cooperative Learning Effects on College Students＇ Learning Anxiety

Since Krashen put forward the Affective Filter Hypothesis, more and more concern has been paid to the anxiety problem in Second and foreign language teaching and learning. Meanwhile, CL （cooperative learning） has gained much attention in recent years, both at home and abroad. Most researches （Oxford ＆ Ehrman, 1993; Kagan, 1994; Slavin, 1995） on CL indicated that CL is a classroom procedure which can lower anxiety and improve learning outcomes. Although the researches abroad have suggested that CL has a positive impact on reducing foreign language learning anxiety, few empirical researches on CL have been conducted in China. Moreover, according to the author＇s observation, anxiety is most obvious in oral English activities. Therefore, this thesis attempts to investigate some Chinese non-English freshmen＇s foreign language learning anxiety. Two classes are involved in the study： one as the experimental class instructed with CL method, the other as the control class taught with the traditional teaching method. By using a classical instrument, the FLCAS （foreign language classroom anxiety scale）, this study examined the subjects＇ foreign language learning anxiety. According to the analysis and comparison of the first and second FLCAS, the author finds CL has a significant effect on reducing students＇ foreign language learning anxiety.     

K-12 Science and Mathematics Teachers’ Beliefs About and Use of Inquiry in the Classroom

A survey instrument was developed and administered to 1,222 K-12 mathematics and science teachers to measure their beliefs about and use of inquiry in the classroom. Four variables (grade level taught, content area taught, level of support received, and self-efficacy for teaching inquiry) were significantly correlated to two dependent variables, percentage of time that students are engaged in inquiry during a typical lesson and the perceived ideal percentage of instructional time that should be devoted to inquiry. Specifically, elementary school teachers reported using inquiry-based practices more than either middle-school or high-school teachers; similarly, elementary-school teachers believed such practices should be used more often. All groups, however, reported believing in an ideal percentage of time devoted to inquiry instruction that was significantly greater than their reported percentage of time actually spent on inquiry instruction. A disordinal effect was found between grade level taught and content area taught; at the elementary level, science teachers reported both an ideal and actual percentage of time on inquiry higher than those reported by the math teachers, while at the high school level math teachers reported both an ideal and actual percentage of time on inquiry higher than those reported by the science teachers. No correlations were found between typical and ideal percentage of time devoted to inquiry and subject matter content knowledge training, gender, years of teaching experience, or maximum degree earned.     

Relational Analysis of College Science‐Major Students’ Epistemological Beliefs Toward Science and Conceptions of Learning Science

In recent years, there has been an increasing interest among educational researchers in exploring the relationships between learners’ epistemological beliefs and their conceptions of learning. This study was conducted to investigate these relationships particularly in the domain of science. The participants in this study included 407 Taiwanese college science‐major students. All of them responded to two major questionnaires, one assessing their scientific epistemological beliefs (SEBs) and the other one probing their conceptions of learning science (COLS). The SEB questionnaire included four factors: “certainty,” “source,” “development,” and “justification” of science knowledge. The COLS survey consisted of six factors in a hierarchical order, that is, learning science as “memorizing,” “preparing for tests,” “calculating and practicing,” “increasing one’s knowledge,” “application,” and “understanding and seeing in a new way.” The students’ confidence and interest toward learning science were also assessed by additional questionnaire items. Stepwise regression analyses, in general, showed coherence between students’ SEBs and their COLS, indicating that the sophistication of SEBs was consistent with less agreement with lower‐level COLS (such as “memorizing” and “preparing for tests”) as well as more agreement with higher‐level COLS (such as “understanding and seeing in a new way”). However, the SEB’s “justification” factor was positively related to almost all of COLS factors from the lower‐level to higher‐level. This study finally found that among all of the SEB and COLS factors, the “preparing for tests” factor in COLS was the solely significant variable for predicting students’ interest in science and confidence toward learning science.     

The Effects of College Students’ Personal Values on Changes in Learning Approaches

Many studies of changes in learning approaches have used data from different age groups at one point in time only (Gow and Kember, High Educ 19:307–322, 1990; Watkins and Hattie, Br J Educ Psychol 51:384–393, 1981) or have analyzed the effects of just two or three factors using single level analytical techniques (Cano, Br J Educ Psychol 75:203–221, 2005; Duckwall et al., Res High Educ 32(1):1–13, 1991; Jay and Love, NCSSSMST J 7(2):4–8, 2002; Loo, Educ Psychol, 17(1/2), 1997; Watkins and Hattie, Hum Learn 4:127–141, 1985; Zeegers, Br J Educ Psychol 71:115–132, 2001). This study employs multilevel modeling as a more appropriate technique for the analysis of longitudinal data to examine factors influencing changes in the learning approaches of 153 international undergraduate students over a 3-year period. Specifically, using hierarchical linear modeling (HLM), the effects of personal values (level-2) on learning approaches and changes in them over time (level-1) are examined. Results show no changes within students in the deep and surface approaches to learning but a significant decline for the achieving approach, particularly for students who previously experienced a more formal teaching authority. Furthermore, students’ personal values in terms of security, achievement and hedonism affect the achieving approach while no effects emerge for the personal values of tradition, conformity, universalism, self-direction and stimulation. Finally, these effects can be observed while no significant effects emerge for gender, discipline and ability.     

Effects of Cooperative Learning on Students’ Understanding of Metallic Bonding

The present study focused on investigating the effectiveness of instruction via newly developed teaching materials based on cooperative learning when compared to a traditional approach, on ninth grade students’ understanding of metallic bonding. Fifty-seven ninth grade science students from two science classes in the same high school participated in this study. The same teacher taught metallic bonding with cooperative learning to an experimental group (N = 28) and with a traditional teacher centred approach to a control group (N = 29). Students’ conceptual understanding of metallic bonding was measured using the Metallic Bonding Concept Test. The results from the Student’s t test indicated that the mean score of the students in the experimental group was significantly higher in the experimental group (78.60, SD = 8.62), than in the control group (54.33, SD = 9.11) after treatment. In the light of the results from the concept test and individual interviews, the misconceptions related to metallic bonding were found less in the experimental group than traditional. Five of these misconceptions were firstly identified in this study. The individual interviews which were done with students from experimental group immediately after the instruction showed that students had positive perceptions about their cooperative work experiences.     

Effects of a Collaborative Science Intervention on High Achieving Students’ Learning Anxiety and Attitudes toward Science

This study investigated the effects of a collaborative science intervention on high achieving students’ learning anxiety and attitudes toward science. Thirty‐seven eighth‐grade high achieving students (16 boys and 21 girls) were selected as an experimental group who joined a 20‐week collaborative science intervention, which integrated and utilized an innovative teaching strategy. Fifty‐eight eighth‐grade high achieving students were selected as the comparison group. The Secondary School Student Questionnaire was conducted to measure all participants’ learning anxiety and attitudes toward science. In addition, 12 target students from the experimental group (i.e., six active and six passive students) were recruited for weekly classroom observations and follow‐up interviews during the intervention. Both quantitative and qualitative findings revealed that experimental group students experienced significant impact as seen through increased attitudes and decreased anxiety of learning science. Implications for practice and research are provided.
