Classroom climate and students’ goal structures in high-school biology classrooms in Kenya

This study examined classroom climate and student goal structures in high-school biology classrooms in Kenya. Participants included 891 students and their teachers in Grades 10 and 11 from two same-sex boarding schools—one for boys and the other for girls. School differences were found on all classroom climate aspects except teacher support and competition. Relative to tenth graders, eleventh graders perceived their classrooms to be higher in teacher support, task focus, competition, rule strictness, and innovation. There were school and grade differences in students’ goal structures, with School 1 students, relative to School 2 students, perceiving more personal performance-approach goals and their teachers as encouraging performance-approach goals. Eleventh graders reported more performance-approach goals at both the personal and teacher levels. Teachers perceived their classroom climates more positively than their students. Observation data provides interpretative information.     

Absolute value inequalities: high school students’ solutions and misconceptions

Inequalities are one of the foundational subjects in high school math curricula, but there is a lack of academic research into how students learn certain types of inequalities. This article fills part of the research gap by presenting the findings of a study that examined high school students’ methods of approaching absolute value inequalities, their common mistakes, misconceptions, and the possible sources of these mistakes and misconceptions. The research study used two tools—a questionnaire and personal interviews. The questionnaire was given to 481 students in the 10th and 11th grades in Israel who studied mathematics at intermediate and advanced levels. It was administered after the students had studied inequalities. Thirty-two students were interviewed in order to find their ways of thinking and the sources of their errors. The main types of mistakes that students consistently made when solving absolute value inequalities were found. Based on the study’s findings, teachers can understand students’ thought processes and use this understanding to conduct remediation and enhance mathematics instruction.     

Perceptual Influence of Ugandan Biology Students’ Understanding of HIV/AIDS

In Uganda, curbing the spread of HIV/AIDS has largely depended on public and private media messages about the disease. Media campaigns based on Uganda’s cultural norms of communication are metaphorical, analogical and simile-like. The topic of HIV/AIDS has been introduced into the Senior Three (Grade 11) biology curriculum in Uganda. To what extent do students’ pre-conceptions of the disease, based on these media messages influence students’ development of conceptual understanding of the disease, its transmission and prevention? Of significant importance is the impact the conceptions students have developed from the indirect media messages on classroom instruction on HIV/AIDS. The study is based in a theoretical framework of conceptual change in science learning. An interpretive case study to determine the impact of Ugandan students’ conceptions or perceptions on classroom instruction about HIV/AIDS, involving 160 students aged 15–17, was conducted in four different Ugandan high schools: girls boarding, boys boarding, mixed boarding, and mixed day. Using questionnaires, focus group discussions, recorded biology lessons and informal interviews, students’ preconceptions of HIV/AIDS and how these impact lessons on HIV/AIDS were discerned. These preconceptions fall into four main categories: religious, political, conspiracy and traditional African worldviews. Results of data analysis suggest that students’ prior knowledge is persistent even after biology instructions. This has implications for current teaching approaches, which are mostly teacher-centred in Ugandan schools. A rethinking of the curriculum with the intent of offering science education programs that promote understanding of the science of HIV/AIDS as opposed to what is happening now—insensitivity to misconceptions about the disease—is needed.     

THE EFFECT OF COOPERATIVE LEARNING STRATEGIES ON ELEMENTARY STUDENTS’ SCIENCE ACHIEVEMENT AND SOCIAL SKILLS IN KUWAIT

This study compares the effects of two methods of teaching—teacher-centered and cooperative learning—on students’ science achievement and use of social skills. The sample consists of 163 female elementary science students in 8 intact grade 5 classes who were assigned to 2 instructional methods and were taught an identical science unit by 4 classroom teachers. The students’ science achievement was measured by a researcher-designed achievement test given to students as a pretest and a posttest. Students’ social skills were determined by a researcher-designed survey administered as a pretest and posttest. Analysis of the achievement test scores and the social skills survey responses revealed that cooperative learning strategies have significantly (p > 0.05) more positive effects on both students’ achievement and social skills than teacher-centered strategies. These results provide an evidential base to inform policy decisions and encourage and persuade teachers to implement cooperative learning methods in Kuwaiti classrooms.     

An exploratory study into the complexity of relations between physics lecturers’ crafting of practice and students’ expectations of quality teaching

This study contributes to research that characterises the affective learning that is evoked and taken on by students in response to their perceptions of their contextual learning environments. Interview-discussions were held with lecturers of both introductory and higher-level physics courses (n = 3) concerning how they formulated their patterns of teaching in terms of a particular conceptual framing that they considered to best optimize making learning possible. Subsequently their students (n = 212) were asked with written questions, and some select follow-up interview-discussions, to describe what they expected from ‘a good physics lecturer’. The relationships between these two things—the lecturer’s crafting of practice and the students’ expectations of quality teaching—were investigated. Results show that students’ expectations tend to match their lecturers’ practice, indicating that students are strongly influenced by a contextually based appreciation of ‘good’ teaching.     

Using Photographs to Probe Students’ Understanding of Physical Concepts: The Case of Newton’s 3rd Law

The starting point of the present research is the following question: since we live in an age that makes increasing use of visual representations of all sorts, is not the visual representation a learner constructs a window into his/her understanding of what is or is not being learned? Following this direction of inquiry, the present preliminary study introduces and evaluates a novel technique for pinpointing learners’ misconceptions, namely, one that has learners create and interpret their own photographs (CIP). 27 high-school students and 26 pre-service teacher trainees were asked to assume the role of textbook designers and create a display—photograph plus attached verbal explanation—which, in their opinion, best depicted Newton’s 3rd law. Subsequent analysis of the participants’ photographs yielded the following six misconception categories: 3rd law not depicted; 3rd law depicts a sequence of events; tendency to introduce irrelevant entities in explanations; the word ‘reaction’ used colloquially; tendency to restrict the application of the third law to dynamic situations; and informal explanations in which the word “force” is absent. The findings indicate that, indeed, the CIP method can be effectively employed to elicit, detect, and investigate learners’ misconceptions. The CIP method joins the growing efforts to utilize the yet relatively untapped potential of visual tools for science education purposes.     

Cultural resources of minority and marginalised students should be included in the school science curriculum

This paper responds to Schademan’s “What does playing cards have to do with science? A resource—rich view of African American young men”, and takes a resource-rich view to explore the notion of agency and elements of cultural resources that minority and marginalised students bring to the classroom. The paper examines the deficit model, the need to adopt capacity building perspective, and a classroom study, which sought to contextualise capacity building with a group of Australian indigenous students in a science class. As science educators, we need to reject the deficit model by developing capacity building pedagogies that affirm minority and marginalised students’ lived languages, experiences and knowledge in their learning.     

THE PRACTICALITY OF IMPLEMENTING CONNECTED CLASSROOM TECHNOLOGY IN SECONDARY MATHEMATICS AND SCIENCE CLASSROOMS

Connected classroom technology (CCT) is a member of a broad class of interactive assessment devices that facilitate communication between students and teachers and allow for the rapid aggregation and display of student learning data. Technology innovations such as CCT have been demonstrated to positively impact student achievement when integrated into a variety of classroom contexts. However, teachers are unlikely to implement a new instructional practice unless they perceive the practical value of the reform. Practicality consists of three constructs: congruence with teacher’s values and practice; instrumentality—compatibility with the existing school structures; and cost/benefits—whether the reward is worth the effort. This study uses practicality as a framework for understanding CCT implementation in secondary classrooms. The experiences of three science teachers in their first year implementing CCT are compared with matched-pair mathematics teachers. Findings suggest that despite some differences in specific uses and purposes for CCT, the integration of CCT into regular classroom practice is quite similar in mathematics and science classrooms. These findings highlight important considerations for the implementation of educational technology.     

A Cross-Analysis of the Mathematics Teacher’s Activity. An Example in a French 10th-Grade Class

The purpose of this paper is to contribute to the debate about how to tackle the issue of ‘the teacher in the teaching/learning process’, and to propose a methodology for analysing the teacher’s activity in the classroom, based on concepts used in the fields of the didactics of mathematics as well as in cognitive ergonomics. This methodology studies the mathematical activity the teacher organises for students during classroom sessions and the way he manages¹ the relationship between students and mathematical tasks in two approaches: a didactical one [Robert, A., Recherches en Didactique des Mathématiques 21(1/2), 2001, 7–56] and a psychological one [Rogalski, J., Recherches en Didactique des Mathématiques 23(3), 2003, 343–388]. Articulating the two perspectives permits a twofold analysis of the classroom session dynamics: the “cognitive route” students are engaged in—through teacher’s decisions—and the mediation of the teacher for controlling students’ involvement in the process of acquiring the mathematical concepts being taught. The authors present an example of this cross-analysis of mathematics teachers’ activity, based on the observation of a lesson composed of exercises given to 10th grade students in a French ‘ordinary’ classroom. Each author made an analysis from her viewpoint, the results are confronted and two types of inferences are made: one on potential students’ learning and another on the freedom of action the teacher may have to modify his activity. The paper also places this study in the context of previous contributions made by others in the same field.     

Closing the Gap: Inquiry in Research and the Secondary Science Classroom

Teaching students how to conduct authentic scientific inquiry is an essential aspect of recent science education reform efforts. Our National Science Foundation-funded GK-12 program paired science graduate students—fellows—with secondary science teachers in order to enhance inquiry-based instruction. This research examined the roles of the fellows, teachers, and school culture in the implementation of inquiry and the fellows’ conceptions of classroom inquiry versus that in their own research. Qualitative data were collected for two academic years. Overall, the classrooms shifted toward a more inquiry-oriented approach over the academic year. Several aspects of school culture influenced inquiry implementation. Fellows described their research as similar in overall structure but less constrained by known concepts, less guided by mentors, and more in-depth than that of secondary school students. The teacher-fellow scientist partnership is a potentially effective professional development model to create positive and lasting change within the science classroom.     

Muslim Egyptian and Lebanese Students’ Conceptions of Biological Evolution

In this study, we investigated distinctions among the diversity of religious traditions represented by Lebanese and Egyptian Muslim high school students regarding their understanding and acceptance of biological evolution and how they relate the science to their religious beliefs. We explored secondary students’ conceptions of evolution among members of three Muslim sects—Sunni, Shiite, and Druze—in two cultural contexts; one in which the overwhelming majority of the population is Muslim (Egypt) and another in which there is a sizable Christian community (Lebanon). Data were collected via surveys that examined students’ scientific and religious understandings of evolution among 162 Egyptian students (all Sunni Muslims; 63% females and 37% males) and 629 Lebanese students (38.5% Sunni, 38% Shiite, and 23.5% Druze; 49% females and 51% males). Additional data were collected via semi-structured interviews with 30 Lebanese students to allow triangulation of data for accuracy and authenticity. Results indicate that many Egyptian and Lebanese Muslim students have misconceptions about evolution and the nature of science which often lead to rejection of evolution. Also, Lebanese Sunni and Shiite students and Egyptian Sunni students tend to exhibit high levels of religiosity, and these students report that their religious beliefs influence their positions regarding evolution. Finally, Sunni and Shiite Lebanese students have religious beliefs, conceptions of evolution, and positions regarding evolution similar to those of Sunni Egyptian students. These conceptions and positions, however, are substantially different from those of Druze Lebanese students.     

ACADEMIC DISHONESTY: A Zero Tolerance Professor and Student Registration Choices

College and university faculty and administrators are responsible for constructing academic honesty policies and communicating them to students. This is often attempted through institutional honesty policies and university-wide honor codes. While these approaches have been widely researched, less attention has been given to the role of individual faculty members. That role is examined in this study by addressing student reactions to professors based on their academic honesty policies. In addition to demographic information, data were gathered about student attitudes and beliefs concerning academic dishonesty and their decision to enroll in or avoid a course being taught by a professor with zero tolerance for academic dishonesty. The findings regarding different instructors’ approaches toward academic dishonesty indicate that an intolerant policy will keep dishonest students away, but at a price—it will also detract many honest students.     

Evaluation of the physical classroom by students and professors: a lens model approach

A method for linking classroom evaluations to specific physical properties and for comparing the evaluations of different groups is described and illustrated. Thirty-five college classrooms were photographed and shown to 20 professors and 51 undergraduate students, each of whom evaluated the friendliness of and their overall preference for all the classrooms. Seven physical properties of the classrooms were reliably assessed by independent observers. Using a modified Brunswik lens model, the relations between the physical properties and the evaluations by the two groups were established and compared. Between 40 and 57 per cent of the variance in the evaluations could be explained from only three classroom properties: view to outdoors, seating comfort and seating arrangement. Evaluations by the students and professors were surprisingly similar, an encouraging sign for classroom designers.     

Using the Critical Thinking Belief Appraisal to assess the rigor gap

In a line of research employing a survey instrument, the Critical Thinking Belief Appraisal, teachers supported critical-thinking (CT) activities more for high- than low-advantage learners, likely exacerbating a “rigor gap” implicated in persistent achievement gaps. Such beliefs were less likely to be espoused by expert teachers than randomly selected ones, and teacher-education programs mitigated these beliefs but did not expunge them, suggesting a need for interventions that foster belief change. Six issues were found to be associated with support for low-CT activities with low-advantage populations—learners’ prior knowledge, time constraints, influence of parents, influence of colleagues, learners’ level of motivation, and learners’ level of ability. The rigor gap may be ameliorated through teacher-education practices that encourage teachers to (a) reflect on their existing beliefs, their experiences as students, their field experiences, classroom scenarios, and models of best practice, and (b) create instructional plans featuring high-CT activities for low-advantage learners.     

Print and Image Integration of Science Texts and Reading Comprehension: A Systemic Functional Linguistics Perspective

Systemic functional linguistics (SFL) was the foundation for this study that explored the effect of science text and image integration on grade 9 students’ reading comprehension. Two texts in Chinese on the moon phase with different print and image integration were compared—a traditional textbook (TT) used in Taiwanese junior high schools and a systemic functional linguistics text (SFLT) created by the authors for this study. These two texts contained similar concepts but had major differences in several features: technicality, representational structure, degree of modality, and interaction between print and image. A control-experimental design with pretest, posttest, and semi-structured interviews was used. In total, 132 junior high school students were randomly assigned to two groups: one group (n=69) read the TT and the other group (n=63) read the SFLT. Sixteen students with both high and low performances in the posttest were purposely selected as the subjects of the follow-up interviews. Major findings were: (a) students who read the SFLT demonstrated significantly better achievement than those who read the TT, and (b) students who read the TT generated more misconceptions about the moon phase and had greater difficulty in making sense of the images than the students who read the SFLT. Accordingly, SFL may serve as a useful theoretical framework and tool in the design of textbooks and may have a practical application in the science classroom.     

Pedagogical content beliefs: global, content domain-related and situation-specific components

Although teachers’ professional knowledge and instructional beliefs are known to have a variety of subcomponents, research on the structure and interrelations of these subcomponents is relatively scarce. This article presents some findings of a preliminary, quantitative empirical study examining the relationships between mathematics teachers’ views concerning specific classroom situations, their content domain-specific pedagogical content beliefs and their more global instruction-related beliefs. The findings suggest that global beliefs—in terms of cognitive constructivist or direct transmission views of teaching and learning, on the one hand, and beliefs about the stability of individual mathematical abilities, on the other—can impact teachers’ content domain-specific beliefs and their views related to videotaped classroom situations from introductory lessons on geometrical proof.     

Science Teacher Learning of MBL-Supported Student-Centered Science Education in the Context of Secondary Education in Tanzania

Science teachers from secondary schools in Tanzania were offered an in-service arrangement to prepare them for the integration of technology in a student-centered approach to science teaching. The in-service arrangement consisted of workshops in which educative curriculum materials were used to prepare teachers for student-centered education and for the use and application of Microcomputer Based Laboratories (MBL)—a specific technology application for facilitating experiments in science education. Quantitative and qualitative data were collected to study whether the in-service arrangement impacted teacher learning. Teacher learning was determined by three indicators: (1) the ability to conduct MBL-supported student centered science lessons, (2) teachers’ reflection on those lessons and (3) students’ perceptions of the classroom environment. The results of the research indicate that the teachers’ were able to integrate MBL in their science lessons at an acceptable level and that they were able to create a classroom environment which was appreciated by their students as more investigative and open-ended.     

Misconceptions and light: A curriculum approach

This paper describes the method used by the author to teach a class of Year 8 students about light and its properties so that the students’ own ideas were considered and their misconceptions addressed. To achieve this a series of teaching modules were designed using a model of conceptual change suggested by Posner and his colleagues at Cornell University. Students’ prior misconceptions about light were identified using a pretest developed by the author. After teaching a posttest was used to determine if the teaching method resulted in a lower level of misconceptions. Interviews from seven students selected at random and the observations gathered by a participant observor were used to verify results. It was found that the teaching method resulted in a lower level of misconceptions in the sample and this was confirmed by the results of the interviews and participant observation. This paper concentrates on the design and content of one of the teaching modules. Specializations: students’ misconceptions in science.     

Improper use of linear reasoning: An in-depth study of the nature and the irresistibility of secondary school students' errors

Several recent ascertaining studies revealed a deep-rooted and almost irresistible tendency among 12–16-year old students to improperly apply the linear or proportional model in word problems involving lengths, areas and volumes of similar plane figures and solids. While these previous studies showed to what extent students' improper use of linear reasoning is affected by different characteristics of the task, it remained largely unclear what aspects of their knowledge base are responsible for the occurrence and strength of this phenomenon and how these aspects relate to other more general misconceptions and buggy rules identified in the literature. This paper reports an in-depth investigation by means of individual semi-standardised interviews aimed at analysing the thinking process underlying students' improper linear reasoning and how this process is affected by their mathematical conceptions, beliefs and habits. During these interviews,students' solution processes were revealed through a number of well-specified questions by the interviewer with respect to one single non-linear application problem, as well as through their reactions to subsequent kinds of cognitive conflict. The interviews provided a lot of information about the actual process of problem solving from students falling into the ‘linearity trap’ and the mechanism behind it. Although some students seem to really ‘believe’ that quantities are always linked proportionally, their improper use of linearity often results from superficial and intuitive reasoning, influenced by specific mathematical conceptions, habits and beliefs leading to a deficient modelling process.

Integrating Gender and Group Differences into Bridging Strategy

The main goal of this study was to integrate gender and group effect into bridging strategy in order to assess the effect of bridging analogy-based instruction on sophomore students’ misconceptions in Newton’s Third Law. Specifically, the authors developed and benefited from anchoring analogy diagnostic test to merge the effect of group and gender into the strategy. Newton’s third law misconception test, attitude scale toward Newton’s third law, and classroom observation checklists were the other measuring tools utilized throughout this quasi-experimental study. The researchers also developed or used several teaching/learning materials such as gender and group splitted concept diagrams, lesson plans, gender splitted frequency tables, make sense scales, PowerPoint slides, flash cards, and demonstrations. The convenience sample of the study chosen from the accessible population involved 308 students from two public universities. The results of multivariate analysis of covariance indicated that the bridging strategy had a significant effect on students’ misconceptions in Newton’s third law whereas it had no significant effect on students’ attitudes toward Newton’s third law.
