Re-Examining the Similarities Between Teacher and Student Conceptions About Physical Science

There is a large body of research that has explored students’ misconceptions about science phenomena. Less research, however, has been devoted to identifying teachers’ misconceptions, but the results of the few existing studies demonstrate that teachers and students possess similar misconceptions. This study explored the physical science conceptions of 103 elementary science teachers to determine whether, after three decades of misconception research, teachers still possess conceptions similar to those held by students. We found that our teachers expressed misconceptions regarding gravity, magnetism, gases, and temperature that were similar to common student misconceptions. Suggestions for improving science professional development programs are discussed.     

The University Experiences of Students with Learning Disabilities

To explore the university experiences of students with learning disabilities (LD), 63,802 responses to the 2014 Student Experience in the Research University Survey were analyzed. Compared to other students, those with self‐reported LD (5.96 percent) had difficulty with assignments and had more obstacles caused by nonacademic responsibilities and imposed by their skill levels. Students with self‐reported LD sensed more bias toward people with disabilities on campus, and they were less satisfied with their overall experience. Interactions between disability status and age suggested even more challenges for older students who self‐reported LD. Approximately one‐third of students who self‐reported LD received accommodations. The rate of accommodations was higher among individuals who were wealthy, who lived alone, and who were out‐of‐state students. Compared to students who self‐reported LD but reported no accommodations, those with accommodations had more contact with faculty and less difficulty with assignments.     

Inquiring into the Nature of STEM Problems

Around the world, there is a growing interest in integrated STEM (science, technology, engineering, mathematics) education. Many of the calls for integrated STEM emphasize the need for students to engage with complex STEM problems that cut across multiple fields. Yet there is a need to clarify the nature of those problems and differentiate STEM problems from those of different kinds. This conceptual work examines the nature of STEM problems in order to inform pre-college educational efforts in STEM. A typology is introduced that situates STEM problems within a broader space of problems within STEM and non-STEM fields, and the characteristics of STEM problems are described. The typology and characteristics are then applied to different approaches to STEM instruction. A key conclusion is that many integrated STEM education efforts tend to focus on STEM problems that are narrowly framed and that do not include attention to social, cultural, political, or ethical dimensions. However, alternative instructional approaches exist that re-introduce those missing dimensions. If STEM education is to prepare students to grapple with complex problems in the real world, then more attention ought to be given to approaches that are inclusive of the non-STEM dimensions that exist in those problems.

     

Getting serious about institutional performance in student retention: Research-based lessons on effective policies and practices

The Indiana Project on Academic Success and the College Board Pilot Study on Student Retention evaluated the effectiveness of a variety of approaches to student retention. The authors share empirically grounded insights gleaned from this research.     

Zero‐Slack,Noncritical Paths

The critical path method/program evaluation and review technique method of project scheduling is based on the importance of managing a project's critical path(s). Although a critical path is the longest path through a network, its location in large projects is facilitated by the computation of activity slack. However, logical fallacies in oft‐repeated statements of the relationship between slack and the critical path make it easy to overlook the phenomenon of zero‐slack, noncritical paths. This article points out the fallacies and then describes and illustrates the phenomenon. We conclude with teaching recommendations to avoid suboptimal decisions in reducing project duration.     

The Impact of a Professional Development Program on Teachers' Mathematical Knowledge for Teaching,Instruction, and Student Achievement

In this paper, we describe findings from a three-year evaluation of a well-developed mathematics professional development program that is commercially available on a wide scale. The professional development is designed to improve teachers' mathematical knowledge for teaching and to enable them to elicit more student thinking and reasoning during mathematics lessons. Specifically, it focused on helping teachers (a) learn more mathematics, (b) understand how children learn math, (c) use formative assessment to develop insight into what specific students know and do not know, and (d) develop effective classroom instructional strategies that enable student problem solving. Participants included 105 fourth- and fifth-grade teachers teaching in 19 low-income schools within a single district. Teachers were randomly assigned within schools either to a “business as usual” control group or to receive the professional development. The training consisted of a week-long summer institute and four to six in-service days during the school year. The training was run by full-time trained associates. We find some limited evidence of positive impacts on teachers' mathematical knowledge for teaching, but no effects on instructional practice or student outcomes.     

Graphical Analysis of Test Items

Graphical Item Analysis (GIA) visually displays the relationship between the total score on a test and the response proportions of the correct and false alternatives of a multiple-choice item. The GIA method provides essential and easily interpretable information about item characteristics (difficulty, discrimination and guessing rate). Low quality items are easily detected with the GIA method because they show response proportions on the correct alternative which decrease with an increase of the total score, or display response proportions of one or more false alternatives which do not decrease with an increase of the total score. The GIA method has two main applications. Firstly, it can be used by researchers in the process of identifying items that need to be excluded from further analysis. Secondly, it can be used by test constructors in the process of improving the quality of the item bank. GIA enables a better understanding of test theory and test construction, especially for those without a background in psychometrics. In this sense, the GIA method might contribute to reducing the gap between the world of psychometrists and the practical world of constructors of achievement tests.
