Unpacking the CRT in Negotiating White Science

In this forum, we summarize CRT’s origins, tenets common to most CRT writings, and CRT’s evolution. We discuss Yerrick’s article Negotiating White Science with respect to certain CRT premises. Specifically, we use the CRT tenet of racism as emphasized in first- and second-generation CRT and CRT elements liberal racial ideology and voices of color to critically examine Yerrick’s propositions.     

Student perceptions of continuous summative assessment

This paper reports the effect of continuous summative assessment on the behaviour and learning environment of students. Assessing the performance of students is considered to be the most important thing a teacher can do for their students and it can have a profound effect on their learning. Continuous summative assessment was introduced as a form of assessment on a module within an undergraduate degree at a UK university. Student perceptions of the process were sought via a questionnaire and interviews. The paper describes the effect the assessment had on student motivation, their approach to learning and the change to their learning environment. The conclusion reached is that while continuous summative assessment may be time‐consuming to administer, the rewards of an enhanced learning environment for students outweigh the additional burden on staff. The results should be of interest to those academics who are concerned with assessment and its impact on behaviour.     

Teaching practices in Grade 5 mathematics classrooms with high-achieving English learner students

Teachers need more clarity about effective teaching practices as they strive to help their low-achieving students understand mathematics. Our study describes the instructional practices used by two teachers who, by value-added metrics, would be considered “highly effective teachers” in classrooms with a majority of students who were English learners. We used quantitative data to select two fifth-grade classrooms where students, on average, made large gains on a mathematics achievement test, and then examined teaching practices and contextual factors present in each classroom. Participants included two teachers from a mid-Atlantic district and their students who were 67% English learners and 68% economically disadvantaged. We found that the use of multiple representations of mathematics concepts, attention to vocabulary building, individual and group checks for understanding and error analysis were prevalent practices in both high gains classrooms. Also, class sizes ranged from 12–19 students. Discussion focuses on whether observed practices are aligned with recommended teaching practices for English learner students.     

Technologically mediated complex problem‐solving on a statistics task

Simulations on computers can allow many experiments to be conducted quickly to help students develop an understanding of statistical topics. We used a simulation of a challenging problem in statistics as the focus of an exploration of situations where members of a problem‐solving group are physically separated then reconnected via combinations of computer and communications technology to work collaboratively on the simulation. The particular focus in this work was on trying to understand how students could use a system which allowed them to conduct variable based practical experiments in order to help them develop their knowledge and understanding of a statistics topic. We wished to develop an understanding of the virtual space created by shared simulations and video communication tools for supporting collaborative work between people at a distance. The paper reports on an experiment involving 48 subjects using this virtual space to establish the impact on their statistics understanding and to map their use of this distributed environment for learning. It establishes that the virtual space is effective for learning, and that the video conferencing condition which allows for eye contact between the pairs has some advantages for successful problem‐solving with the simulation. In addition the experimental setting provided some opportunities for exploring subjects' understanding of statistical and experimental concepts.     

Mexican-American and Anglo-American Children's Responsiveness to a Theory-Centered AIDS Education Program

Third, fifth, and seventh graders, most of them Mexican-American, were exposed to an empirically based and culturally sensitive AIDS curriculum designed to replace their intuitive theories with a coherent, scientific account of the causal processes that lead from risk behavior to AIDS symptomatology. Compared to students in control classes, experimental students knew more about AIDS risk factors and AIDS generally, displayed more conceptual understanding of the causes of AIDS and flu, and were more willing to interact with people who have AIDS (although not less worried about AIDS) at posttest and typically at follow-up 10–11 months later. The findings point to the potential value of adopting an intuitive theories approach in assessing and modifying children's concepts of health and illness and suggest, contrary to Piagetian formulations, that even relatively young children can, with appropriate instruction, grasp scientific theories of disease.     

A program to improve elementary teacher preparation in science at Rollins College

Conclusion The goals of this project were to design and implement a series of courses that would better prepare elementary school teachers to teach science and would promote positive attitudes toward science and science teaching. The initial offering of the first series of courses met with moderate success. Although the courses fostered an increase in cognitive knowledge, the magnitude of the improvement was not what we had anticipated. There was no significant improvement in the attitudes of the students toward science or science teaching. The science course has been revised and is currently being offered for both preservice and inservice teachers. The revisions include lengthening the class time, so that the material can be covered at a more relaxed pace, and increasing the amount of active team teaching by the instructors to further emphasize the interrelations between chemistry and biology and to eliminate the fragmentation of the course. It is hoped that these changes will also have a positive impact on the students’ attitudes toward the course and thus toward science in general.
