This paper reports how I addressed the issue of extensive missing values in my PhD study, "Digital Competencies of High School Mathematics Teachers". I collected data using an online survey. Several methods exist to address the issue of missing values. I utilised multiple imputation (MI) as it provides more accurate results. The mean…

Data sprints have emerged as a popular way to involve stakeholders in datawork. In this chapter we discuss what it takes to turn a sprint into a productive situation of inquiry (in the sense of Dewey, 1938). We argue that sprint organizers must work actively to counteract an otherwise docile setting where the preference for agreement between…

While scholars develop research with clear implications for policy and practice, this work has been largely ineffective in influencing thought beyond the academy. In this article, we explore challenges researchers face in designing public scholarship to influence policy. To illustrate, we profile one such effort, the "Opportunity to Learn…

Research in science education is to discover the truth which involves the combination of reasoning and experiences. In order to find out appropriate teaching methods that are necessary for teaching science students problem-solving skills, different research approaches are used by educational researchers based on the data collection and analysis…

Psychologists studying problem solving have, for over 100 years, been interested in the question of whether there are two different modes of solving problems. One mode--problem solving based on analysis--depends on application of past experience to the problem at hand and proceeds incrementally toward solution. The second mode--problem solving…

The study evaluates a semester-long workbook curriculum approach to teaching a college level introductory statistics course. The workbook curriculum required students to read content before and during class and then work in groups to complete problems and answer conceptual questions pertaining to the material they read. Instructors spent class…

Teachers can help students "find" problems by brainstorming potential research ideas connected to interests they already have. Students of all ages can do descriptive, historical, experimental, correlational, and developmental research. Case, field, causal, and comparative research might be more successful with older students. Conducting real…

The nature of controversial programs is discussed, including problems that such programs pose for evaluators and suggested solutions for the problems. Controversial programs are likely to generate news-media attention, internal conflicts (i.e., involving the program and evaluation staffs) and external conflicts (i.e., involving various advocacy…

Motivating students to perform well on assessment tests is difficult when students know the results have no academic consequence. The present study evaluates the influence of assessment context (graded vs. non-graded) on the reliability of an assessment measure. Results indicate the graded condition produces higher reliability (r = 0.71) than the…

South African experiments with an intervention in university chemistry instruction are critiqued for their poor descriptions of the method, problems with research methodology and data, reliability and validity issues, and assumptions made about application of the intervention. The intervention, Academic Support Programs (ASP), taught…

Traces the different paradigmatic pathways followed by educational sociology and educational administration. Educational sociology has followed ideostructural, interpretive, and psychosocial paradigms, with emergent holistic critical perspectives and sociobiological materialism. Educational administration has had one dominant tradition,…

An evaluation of an experimental problem-based medical education curriculum used with 18 first-year students at the Bowman Gray Medical School of Wake Forest University is discussed. The study, which included a matched group of students experiencing a traditional curriculum, provides insights into design problems in such evaluations. (TJH)

This review brings diverse research to bear on the contention that current achievement tests may underestimate students' subject-matter knowledge and problem-solving ability because of the mismatch between the symbolic form that typical achievement tests use and the specificity of students' symbolic encoding that arises from instruction and…
