This study examines preservice teachers’ knowledge in the case of linear functions. Teachers’ knowledge in general consists of their subject matter knowledge and their pedagogical content knowledge. In this study, teachers’ subject matter knowledge is examined by looking at their ability to adapt to different representation modes. The framework for subject matter content knowledge consists of five components: (1) flexibility across formal mathematical symbolisms; (2) flexibility between visual and algebraic representations; (3) flexibility within visual representations; (4) flexibility with real-life situations, and (5) procedural skills. In terms of pedagogical content knowledge, two aspects were examined across five corresponding components. These two aspects were knowledge of students’ conceptions and misconceptions, and teachers’ teaching strategies. The primary source of data for the study was from two tests and six interviews. The results showed preservice teachers performed poorly in terms of representation flexibility. Furthermore, most of the preservice teachers had limited knowledge of the nature and sources of students’ mistakes as well as effective teaching strategies to help students with their misconceptions. In terms of knowledge structure, representation flexibility was found to be significant in both CK and PCK compared to procedural skills. Moreover, the representational flexibility in terms of CK seemed to strongly predict the overall PCK performance. Representational flexibility seemed to be related to the use of instructional representations. Overall, there was a strong relationship between various components of CK and PCK.

The purpose of this study were (a) to examine the effectiveness of a computer simulation program (Computer Simulation for Teaching Critical Thinking on Gender Equality, CSTCT-GE) on preservice teachers¡¦ improvement in professional knowledge for teaching critical thinking and teaching efficacy for critical thinking; and (b) to examine the effects of gender, educational degree, critical-thinking ability, motivation for professional growth, and level of training involvement on preservice teachers¡¦ increase in professional knowledge and teaching efficacy for critical thinking. A one-group pretest-posttest design was employed in the study. Seventy-two preservice teachers participated in the study. The employed instruments were Computer Simulation for Teaching Critical Thinking on Gender Equality (CSTCT-GE), The Test for Professional Knowledge in Teaching Critical Thinking, The Test for Teaching Efficacy in Critical Thinking, the Test of Critical-thinking Skills for Adults, and The Test of professional growth for Junior High School Teachers. The applied analysis methods were descriptive statistics, Hotelling¡¦s T2, repeated measures of variance, multivariate analysis of covariance, and multiple stepwise regression. The main findings of this study were as follows: 1. CSTCT-GE was effective in improving the preservice teachers¡¦ professional knowledge and teaching efficacy for critical thinking. 2. The preservice teachers¡¦ increase of professional knowledge did not have significant effects on their enhancement of teaching efficacy for critical thinking. 3. There were no significant gender and educational degree effects on the preservice teachers¡¦ improvement of professional knowledge and teaching efficacy for critical thinking. 4. There were no significant critical-thinking ability effects on the preservice teachers¡¦ enhancement of teaching efficacy for critical thinking. 5. There were no significant professional growth motivation on the preservice teachers¡¦ improvement of professional knowledge and teaching efficacy for critical thinking. 6. The preservice teachers¡¦ level of training involvement had positive effects on their increase of professional knowledge for teaching critical-thinking but not on their enhancement of teaching efficacy for critical thinking. 7. The preservice teachers¡¦ level of training involvement could effectively predict their professional knowledge for teaching critical thinking in the posttest. 8. The preservice teachers¡¦ level of professional growth motivation could effectively predict their teaching efficacy for critical thinking in both the pretest and the posttest. Finally, the researcher proposed some suggestions for educational organizations, preservice teachers, inservice teachers, and future studies.

The purpose of the study was to investigate the relationship between critical thinking abilities and critical thinking dispositions of preservice teachers in Taiwan. Critical Thinking Scale and Critical Thinking Disposition Scale were administrated to preservice teachers in Taiwan. A total of 1094 valid samples were obtained for investigating preservice teachers¡¦ critical thinking abilities, and 853 valid samples were obtained for investigating preservice teachers¡¦ critical thinking dispositions and the relationship between critical thinking abilities and critical thinking dispositions. The data were analyzed by descriptive statistics, independent sample t-test, one-way ANOVA, one-way MANOVA, and canonical correlation. The results showed: (1) the scores of preservice teachers¡¦ critical thinking abilities and critical thinking dispositions were quite high; (2) female preservice teachers¡¦critical thinking abilities were significantly higher than male preservice teachers¡¦; (3) significant differences of critical thinking abilities across age levels were only found in Interpretation Subscale; (4) there were no significant differences of critical thinking abilities in education levels; (5) critical thinking abilities of preservice teachers at technological and vocational universities were significantly lower than general universities and universities of education; (6)critical thinking abilities of preservice teachers from college of social sciences were significantly lower than those from college of liberal arts and college of science; (7) there were significant differences of critical thinking abilities between those who took philosophical courses and those who did not take philosophical courses; (8) there was no significant relation between preservice teachers¡¦ critical thinking abilities and critical thinking dispositions; (9) preservice teachers¡¦ background, relevant curriculum experiences, and critical thinking dispositions accounted for 13% of critical thinking abilities through two canonical factors.

Given the competing contexts of teacher education, it is important to uncover what teacher educator knowledge concerning curriculum design and development emerges in design, implementation, and instruction during the transition from in-person to online contexts. Yet, there is little research that uncovers teacher educator knowledge in curriculum making generally, and more specifically, how this knowledge is carried forward or changed as teacher educators create and enact online teaching. Because transitions are an important time to uncover tacit and embodied understanding, in this self-study of teacher education practice (S-STEP), I examined my own teacher educator knowledge during planning, teaching, and reflecting as I shifted to teaching online. Seven strands of teacher educator knowledge were represented in analytic narrative vignettes and identified as knowledge of content, fixed and fluid elements of course design, milieu, pedagogical intent, preservice teacher knowledge and belief, the value and fragility of relationships, and theory. Then I examined each of the strands separately as a way to discuss findings more holistically. By shifting the teaching context, I questioned and deepened my knowledge of preparing preservice teachers. Further, the analysis revealed how these seven strands of my teacher educator knowledge were interconnected, made stronger, and interacted differently during the stages of planning, teaching, and reflecting. Such intimate study of my own teacher educator knowledge revealed my obligations, responsibilities, and commitments to preservice teachers and the students they will teach. Studies that examine the shifts in teaching context have the potential to identify and highlight the complexities of teacher educator knowledge, thereby making a useful contribution to the research conversation in teacher education. By recognizing and naming their teacher educator knowledge, teacher educators can sharpen and improve their practice as they design courses, especially including improvements in online teacher education, participate in constructing programs, and defend their programs in accreditation processes.

The failure to staff the nation’s classrooms with highly qualified teachers, especially those in disadvantaged schools, is a problem in American education. Novice teachers who begin teaching in urban, low-income, diverse schools leave the field of education at alarmingly high rates. Schools are not being provided with the teachers they deserve; new teachers are especially ill-prepared to meet the needs of students in high-need urban settings. In return, these lowincome schools are not retaining sufficient numbers of the teachers they do recruit. A teacher’s performance has a tremendous impact on a child’s learning and academic journey. Teacher preparation programs need to increase effectiveness by preparing teachers who perform at a proficient level or higher from the first day they step foot in the classroom. Preservice teachers must have an understanding of how to teach effectively through the use of pedagogical knowledge and culture. Universities can assist prospective teachers to simultaneously learn content and pedagogy through training. The revolving door of teachers leaving impoverished communities must stop. Students are not in warrant of substitute teachers, unqualified or uncertified novice teachers year after year. Teacher preparation programs have a vital role in shaping initial levels of teacher commitment. One way to build this bridge between preparation of teachers for urban or diverse settings is to consider new options for teacher preparation. While teacher preparation programs can offer theories and pedagogies of practice, the use of a virtual reality (VR) environment permits teacher preparation to provide preservice teachers with varied experiences in order to prepare them for a high-need urban setting. This fully immersive environment could allow preservice teachers to create an environment that best supports the needs of their learners, iii strengthening knowledge gained in coursework to examination in the field. A traditional teacher preparation program cannot offer this understanding of pedagogy in a consistent and constant format. It is the obligation of schools and colleges of education to improve teacher education programs. Universities need to prepare culturally responsive educators who can effectively perform in the urban classroom. The purpose of this study was to examine the impact a simulated learning environment had on preservice teachers’ classroom performances as measured by onsite and virtual observations. Pedagogies of practice are described through categories of personal connections, life experiences, engagement and assessment of prior knowledge as demonstrated in reflective writing of preservice teachers who participated in a simulated learning environment versus those who did not. The researcher proposed the use of a VR to provide an expanded view to preservice teacher preparation within a simulated classroom. It was hypothesized this scaffolding of learning beyond typical textbook learning would deepen the knowledge of the preservice teacher, leading to effective performance within a high-need urban setting. A mixed-methods approach of the embedded experimental design was used for collection of both qualitative and quantitative data. The Chi-square Test of Independence, supported by Fisher’s Exact Test and Cramer’s V used to analyze data measured on a nominal scale for the experimental group and control groups. Data analysis showed a significant difference in teacher indicators in three of the four observations. Specifically the preservice teachers (experimental group) who participated in the simulated learning environment related and integrated the subject matter with other disciplines and life experiences and reviewed previous class material before instruction more often than the control group. Key words in context (KWIC), word count and iv content analysis were used to identify themes through language as demonstrated in the reflective writing. Underlying patterns were used to form relationships between performance in the urban classroom after participation in a simulated learning environment, followed by reflective writing in the categories of personal connections, life experiences, engagement and assessment of prior knowledge. The preservice teachers in both the experimental and control groups exhibited many of the teacher behaviors needed in a high-need urban setting through their reflective writing. However, the intervention of TeachLivE™ continued to be an outlier, which not only strengthened the preservice teachers’ reflections but performance in the classroom. The simulated learning environment offered the preservice teachers in the experimental group a medium to learn through doing. Exposure to the tools and methods in TeachLivE™, followed by reflective writing, provided opportunities to improve pedagogies of practice, impacting preservice teacher’s performances in the urban setting. Future research recommendations based on continued observations to gather further data of the study, improvement of performance over time, and an expanded observational group are presented. Academic achievement of the students in the participant’s classrooms who took part in TeachLivE™ in order to analyze whether the variable of TeachLivE™ impacted preservice teacher performance in the urban classroom could be measured. Finally, faculty mentors at the university could design professional development opportunities for novice teachers in TeachLivE™, assisting in coaching and self-reflection of lessons taught, working towards understanding of content and pedagogy. Reflection afterward would be collaborative between novice teachers and faculty mentors based on observations. Scaffolding novice teachers learning while in a simulated environment can be motivating and effective in learning gains.

The relationship between the mission of community colleges and the increasing teacher shortage has become more transparent as many community colleges have implemented teacher education programs to address community needs, the shortage of qualified teachers, and the lack of diversity among teachers. As the community college's teacher education role has increased, many community colleges have responded by adding associate of arts degrees and certificate programs specific to teacher education to tackle the shortage of teachers and the lack of diversity among teachers in the nation's classrooms. The purpose of this study was to examine the effectiveness of one community college's pre-service teacher education program in transferring minority students to a university teacher education program and the likelihood of the students graduating with both bachelor's degrees and teacher certification. This longitudinal ex post facto causal-comparative mixed methods case study involved tracking a cohort of minority students over a 6-year period. Data were gathered from existing teacher education program records for native and transfer students at one community college and two four-year institutions. Unstructured interviews were conducted with administrators over the community college's program. For data analysis, ?2 and Phi Coefficients were conducted to compare the minority students' university transfer and graduation rates to native university students' transfer and graduation rates. Results of the study demonstrated that the minority students were graduating at an observably higher rate than both the native to university students and their respective ethnic peers who began college at two-year colleges at the national level. This study's findings might help community college teacher education programs to increase enrollments of minority students and to address the needs of surrounding communities. The findings contributed to the relatively scarce literature regarding minority teacher preparation in community colleges. The study's findings might also be useful to community colleges looking toward or already implementing similar pre-service teacher education programs. Overall, the results indicated that pre-service teacher education programs at the community college level can be effective at producing transfer students who successfully graduate from four-year teacher education programs.

The goal of this study was to explore technology experiences from a preservice teacher preparation program that requires every preservice teachers and instructors to own a laptop. The participants were a) preservice teachers who were in the program and b) novice teachers who are the program graduates. The setting of this study was a preservice teacher preparation program that involves one-to-one computing throughout in a college of education in a large southwestern university. The research conducted a cross sectional case study. Two preservice teachers across the first, second, and third semesters of the program and two novice teachers in the first year of teaching participated in this research. Various data sources were collected with: a) technological skills and attitude survey, b) related documents such as lesson plans, assignments and school documents, c) observation, and d) interviews. Results of this study showed each participant’s learning environment, technology experiences and technology skills, attitudes and knowledge. All preservice teachers mutually had media cart, instructors’ laptops, students’ laptops, and wireless internet in university classes, and had innovation station, teachers’ computers, printer, telephone, students’ computers, headsets and wireless internet in PK-6 school classes. Throughout the program, university instructors mutually required Email, word processing and electronic submission of assignments to the preservice teachers. The instructors mutually modeled using PowerPoint and Learning Management System (LMS). Preservice teachers in the first semester mutually used video creation, preservice teachers in the second semester used Email and LMS, and preservice teachers in the third semester mutually used search engine, PowerPoint and innovation station. All participants’ technology attitudes were overall positive. Most of the preservice teachers’ technology knowledge was rated accepting level, except Neal, one of the preservice teachers in the third semester, who was rated adapting level. Novice teachers mutually had innovation station, web conferencing devices and students’ laptops in their school. Both of the novice teachers experienced barrier of technology integration due to the necessary devices were already checked out. The novice teachers mutually used innovation station, had overall positive technology attitudes and had technology knowledge at the accepting level. The results led six discussion issues, including a) alignment of technological infrastructure, b) accessibility of technologies, c) limited exposure to technological activities, d) preservice teachers’ technology skills, e) technology experiences from the program and preservice teachers’ technology attitudes, and f) programmatic impact on novice teachers. / text
