Students’ Learning with the Connected Chemistry (CC1) Curriculum: Navigating the Complexities of the Particulate World

The focus of this study is students’ learning with a Connected Chemistry unit, CC1 (denotes Connected Chemistry, chapter 1), a computer-based environment for learning the topics of gas laws and kinetic molecular theory in chemistry (Levy and Wilensky 2009). An investigation was conducted into high-school students’ learning with Connected Chemistry, based on a conceptual framework that highlights several forms of access to understanding the system (submicro, macro, mathematical, experiential) and bidirectional transitions among these forms, anchored at the common and experienced level, the macro-level. Results show a strong effect size for embedded assessment and a medium effect size regarding pre-post-test questionnaires. Stronger effects are seen for understanding the submicroscopic level and bridging between it and the macroscopic level. More than half the students succeeded in constructing the equations describing the gas laws. Significant shifts were found in students’ epistemologies of models: understanding models as representations rather than replicas of reality and as providing multiple perspectives. Students’ learning is discussed with respect to the conceptual framework and the benefits of assessment of learning using a fine-tuned profile and further directions for research are proposed.

Mexican-American Students’ Perceptions of Teachers’ Expectations: Do Perceptions Differ Depending on Student Achievement Levels?

This exploratory study examines the learning beliefs of high and low achieving, low-income Mexican-American students. Semi-structured interviews were conducted with 11 ninth grade students. The qualitative analysis shows that students’ perceptions of their teachers’ expectations of a “good” student or a “not so good” student did not differ along achievement lines. However, the students’ perceptions about what it means to be a good student differentiated the low-achievers from the high-achievers. This study’s findings may be used to inform educators about Mexican-American students’ orientation towards school and learning, in hopes for creating more equitable educational settings where all students achieve to their fullest potential.

Thought Experiments: Determining Their Meaning

This paper considers thought experiment as a special scientific tool that mediates between theory and experiment by mental simulation. To clarify the meaning of thought experiment, as required in teaching science, we followed the relevant episodes throughout the history of science paying attention to the epistemological status of the performed activity. A definition of thought experiment is suggested and its meaning is analyzed using two-dimensional conceptual variation. This method allows one to represent thought experiment in comparison with the congenerous conceptual constructs also defined. A similar approach is used to classify the uses of thought experiments, mainly for the purpose of science curriculum.

The importance of socio-cultural context for understanding students’ meaning making in the study of genetics

In this rejoinder to Ann Kindfield and Grady Venville’s comments on our article “Reconsidering conceptual change from a socio-cultural perspective: Analyzing students’ meaning making in genetics in collaborative learning activities,” we elaborate on some of the critical issues they raise. Their comments make apparent some of the crucial differences between a socio-cultural and a socio-cognitive approach towards conceptual change. We have selected some issues that are addressed, either implicitly or explicitly, in their comments. The main issues discussed are talk and interaction as data, the significance of context in interaction studies, the feasibility of generic claims in small-scale interaction studies, and the difference between studying students’ understanding of science concepts as opposed to studying the construction of meaning.

Individual and school factors affecting students’ participation and success in higher education

The purpose of this study is to identify school factors that affect students’ achievements at the secondary and tertiary levels of education. The analysis included data of 9,894 students who studied in Auckland regional secondary schools in 2004. The results indicate that, although student demographic characteristics are associated with students’ pathways and achievements, schools’ demographic composition did not affect student outcomes. It was found, however, that schools’ organisational factors do have an effect. At the university level, none of the schools’ characteristics was related to students’ achievements at the higher end of the achievement scale (GPA ≥ 4). However, students from private or state-integrated schools were found to be more likely to achieve low GPA (<2) than students who came from state schools. In conclusion, it is suggested that interventions targeting at-risk populations based on demographic factors should focus on individuals or groups rather than on institutions; while school-based interventions should identify the schools by their structure and function rather than by their demographic characteristics.

Analysis of Korean students’ international mobility by 2-D model: driving force factor and directional factor

The purpose of this study is to understand the dynamics of Korean students’ international mobility to study abroad by using the 2-D Model. The first D, the driving force factor, explains how and what components of the dissatisfaction with domestic higher education perceived by Korean students drives students’ outward mobility to seek foreign higher education. The second D, the directional factor, describes the factors that influence the choice of destination country for students’ outward mobility, and is explained by the comparison of Korean students’ perceptions on the images of universities in the U.S., China, the U.K., and Australia and their expectations for higher education in each country (categorized as ‘academic’–‘environmental’). Two questionnaire surveys were conducted to analyze the two D factors and the research findings were integrated into suggestions for each country’s higher education institutions that can be incorporated into their recruitment strategies for international students.

Supporting Teachers’ Use of Technology in Science Instruction Through Professional Development: A Literature Review

Professional development is critical in supporting teachers’ use of technological tools in classrooms. This review of empirical research synthesizes the effective elements of professional development programs that support science teachers in learning about technology integration. Studies are examined that explore how professional development supports technology use within inquiry-based and traditional science instruction. Implications for future research are discussed in four areas: understanding and building on teachers’ beliefs about science and technology; supporting teacher learning by supporting teachers’ examination of students’ work; using technology to support teacher communities and social networks; and sustaining teachers’ learning beyond formal professional development programs.

Educational Attainment as Process: Using Hierarchical Discrete-Time Event History Analysis to Model Rate of Progress

Variables that address student enrollment patterns (e.g., persistence, enrollment inconsistency, completed credit hours, course credit load, course completion rate, procrastination) constitute a longstanding fixture of analytical strategies in educational research, particularly research that focuses on explaining variation in academic outcomes. However, nearly all measures of enrollment patterns are handicapped by untested assumptions about a more fundamental measure, namely students’ rate of progress. In this paper, I first explain how a variety of widely used measures of enrollment patterns are inextricably linked to students’ rate of progress. I then describe a method of modeling mathematically students’ rate of progress that employs hierarchical (multilevel) discrete-time event history analysis of repeated events. I conclude with an empirical example of the application of this method in which I test several hypotheses concerning students’ rate of progress through the remedial math sequence toward the outcome of college-level math competency. In addition to the utility of the method that is proposed here, the issues discussed in this paper have important practical implications for institutional research, particularly with respect to the use of the various measures of enrollment patterns to explain variation in students’ attainment.

Exploration of the contribution of teachers’ knowledge about reading to their students’ improvement in reading

Recent studies of elementary teachers’ knowledge about reading have been built on the premise that teachers need thorough knowledge about language and reading processes, but these studies have provided only limited evidence that teachers’ performance on tests of such knowledge contributes to their students’ reading achievement. The present study was designed to examine the contribution of first- through third-grade teachers’ knowledge about early reading to their students’ improvement on tests of word analysis and reading comprehension, controlling for socio-demographic characteristics of students, their prior reading achievement, and teachers’ educational attainment, professional experiences, and socio-demographic characteristics. Preliminary analyses indicated that the test of teachers’ knowledge had adequate psychometric characteristics. However, performance on this measure of teachers’ knowledge did not significantly explain students’ improvement on the two reading subtests. The complexity of the factors that influence teachers’ knowledge acquisition and the context in which the study was carried out offer possible explanations for these results. In addition, teachers’ content knowledge about reading might not be closely associated with the practices they use in reading instruction, and therefore might not be significantly related to their students’ improvement in reading over a year.

Reconsidering conceptual change from a socio-cultural perspective: analyzing students’ meaning making in genetics in collaborative learning activities

In the learning sciences, students’ understanding of scientific concepts has often been approached in terms of conceptual change. These studies are grounded in a cognitive or a socio-cognitive approach to students’ understanding and imply a focus on the individuals’ mental representations of scientific concepts and ideas. We approach students’ conceptual change from a socio-cultural perspective as they make new meaning in genetics. Adhering to a socio-cultural perspective, we emphasize the discursive and interactional aspects of human learning and understanding. This perspective implies that the focus is on students’ meaning making processes in collaborative learning activities. In the study, we conduct an analysis of a group of students’ who interact while working to solve problems in genetics. In our analyses we emphasize four analytical aspects of the students’ meaning making: (a) the students’ use of resources in problematizing, (b) teacher interventions, (c) changes in interactional accomplishments, and (d) the institutional aspect of meaning making. Our findings suggest that students’ meaning making surrounding genetics concepts relates not only to an epistemic concern but also to an interactional and an institutional concern.

Struggling to Recognize their Existence: Examining Student–Adult Relationships in the Urban High School Context

In today’s reform context, much attention is placed on policies and outcomes and far less emphasis on understanding the social and cultural processes in schools. Using case-study methodology, I examine relationships between low-income, urban high school students of color, and the school adults with whom they interact. Using grounded theory, students’ experiences are analyzed and interpreted through the lens of recognition. Recognition is used as both a theoretical and empirical concept to illuminate students’ experiences and voices, especially since the construct is largely absent in the U.S. education discourse. Students revealed that being known by adults, talking with adults, engaging with adults personally, and experiencing encouraging adults were all critical elements of recognition. I suggest that student–adult relationships, via the practice of recognition in urban schools, needs to be interrogated, deliberate, and political so that the transformative purpose of education can be realized.

Teachers’ Perspectives on a Professional Development Intervention to Improve Science Instruction Among English Language Learners

Our 5-year professional development intervention is designed to promote elementary teachers’ knowledge, beliefs, and practices in teaching science, along with English language and mathematics for English Language Learning (ELL) students in urban schools. In this study, we used an end-of-year questionnaire as a primary data source to seek teachers’ perspectives on our intervention during the first year of implementation. Teachers believed that the intervention, including curriculum materials and teacher workshops, effectively promoted students’ science learning, along with English language development and mathematics learning. Teachers highlighted strengths and areas needing improvement in the intervention. Teachers’ perspectives have been incorporated into our on-going intervention efforts and offer insights into features of effective professional development initiatives in improving science achievement for all students.

Antecedents and Correlates of Course Cancellation in a University “Drop and Add” Period

Most institutions of higher education allow students to drop or add courses in the first 2–3 weeks of each term (D&A). Arguing that course cancellation is not merely an administrative issue involving enrollment trends but represents complex decision making processes taken by students, this study investigated antecedents and correlates of course cancellation during a D&A period in 109 elective courses. Student ratings of the teachers (SRT) and characteristics of the syllabi distributed in the first class session were investigated as predictors of course cancellation. Rates of cancellation were significantly predicted from SRT and from syllabus workload difficulty—lower quality teachers (SRT-based) and more difficult courses (syllabus-based) being cancelled more frequently. Analysis of a sub-sample of truly elective, high-priority courses revealed that these correlations were intensified in teacher-centered lecture courses, but nullified in student-centered seminar courses, in which students write independent research papers. The importance of students’ course selection and course cancellation as decision making processes, the methodology based on institutional data rather than students’ self-reports, and the unique effects of course difficulty on students’ decisions were discussed.

Educational Inequity from the Perspectives of Those Who Live It: Urban Middle School Students’ Perspectives on the Quality of their Education

In interviews with over 250 urban young adolescents, many students make it clear that they are acutely aware of the educational inequities that exist in their schools and that these inequities are having a negative impact on their education. Student voice is used to highlight urban middle school students’ perspectives on the quality of their education particularly in terms of curricular issues, teacher quality, and lack of resources.

Educational choice and persistence in male- and female-dominated fields

Even though female students now make up more than half of all higher education students in many countries, the distribution of women across fields of study is still very uneven. This study examines the gendered nature of recruitment and dropout in higher education. Our results show that students who made gender traditional choices more often had an early preference for the study programme they enrolled in. Moreover, female students reported more often than male students that they had been encouraged by their parents and friends. However, unlike what we expected, there are no differences between students in gender traditional and non-traditional programmes with regard to encouragement from parents and students’ confidence that they had made the right choice. While male students’ dropout is unrelated to the gender composition of educational programmes, women drop out of female-dominated programmes to a lesser extent.

Conceptual change: a discussion of theoretical, methodological and practical challenges for science education

Conceptual change views of teaching and learning processes in science, and also in various other content domains, have played a significant role in research on teaching and learning as well as in instructional design since the late 1970s. An important issue is whether conceptual change can provide a powerful framework for improving instructional practice in such a way that students’ levels of scientific literacy are significantly increased. In this article, the first section provides an overview on the development of conceptual change perspectives. In sections two to six, we examine the different ways that researchers have facilitated the collection of data and empirically evaluated learning as conceptual change based on these different theoretical perspectives. In section seven, we identify key issues of conceptual change with a deliberate emphasis on their contribution to improve instructional practice and conclude the article by posing challenges at theoretical, methodological and practical levels. We contend that conceptual change perspectives still have the potential to significantly improve instructional practice. However, it becomes also evident that actual practice is far from what conceptual change perspectives propose and that change of this practice will be a rather difficult and long-lasting process.

Profiling Teacher/Teaching Using Descriptors Derived from Qualitative Feedback: Formative and Summative Applications

Considerable work has been done on student evaluation of teaching/teachers, but reservations remain about its use for summative purposes. Student ratings are not universally accepted as being reliable, nor can they provide really meaningful information. Qualitative comments can provide a better understanding but they tend not to be user-friendly from lack of structure and connectedness. This study attempts to devise a method for ‘quantifying’ students’ comments to increase their usefulness in complementing/confirming ratings. The quantified results enable the profile construction of what students regard as an effective/ineffective teacher, and enable identification of strengths and weaknesses. Our findings counter some commonly held assumptions, including those which held that high ratings are dependent on small class size and ‘dumbing down’ of courses and the consequent expectation of high grades. The findings also indicate that students value teaching quality more than teacher characteristics, suggesting their ability to make valid judgments about teaching effectiveness.

Designing and implementing a case-based learning environment for enhancing ill-structured problem solving: classroom management problems for prospective teachers

This design-based research study is aimed at two goals: (1) developing a feasible case-based instructional model that could enhance college students’ ill-structured problem solving abilities, while (2) implementing the model to improve teacher education students’ real-world problem solving abilities to deal with dilemmas faced by practicing teachers in elementary classrooms. To achieve these goals, an online case-based learning environment for classroom management problem solving (CBL-CMPS) was developed based on Jonassen’s (in: Reigeluth (ed.) Instructional-Design Theories and Models: A New Paradigm of Instructional Theory, 1999) constructivist learning environment model and the general process of ill-structured problem solving (1997). Two successive studies, in which the effectiveness of the CBL-CMPS was tested while the CBL-CMPS was revised, showed that the individual components of the CBL-CMPS promoted ill-structured problem solving abilities respectively, and that the CBL-CMPS as a whole learning environment was effective to a degree for the transfer of learning in ill-structured problem solving. The potential, challenge, and implications of the CBL-CMPS are discussed.
