Introduces a chemistry lab activity that is suitable for almost any level of science class. Provides students with five solutions and asks them to determine if they have five distinct compounds or if any are the same. (YDS)

Introduces the Mystery Festival at the Shrewsbury Middle School in Massachusetts. Claims that this program will enable the children to collect and analyze data, carry out necessary tests, and develop a scientific approach to solving crimes. Describes the process of setting up this festival and recommendations for adapting the program to suit…

The work aims to improve the assessment of creative problem-solving in science education by employing language technologies and computational-statistical machine learning methods to grade students' natural language responses automatically. To evaluate constructs like creative problem-solving with validity, open-ended questions that elicit…

This article discusses the 4-H Gateway Academies specifically designed to enhance science, technology, engineering, and math (STEM) skills and knowledge in middle school youth. The innovative summer day camps partnered Project Lead the Way--trained teachers with county 4-H staff from University of Wisconsin-Extension (UW-Extension) Cooperative…

Recently, there have been many efforts to use the research techniques developed in the field of physics education research to improve the teaching and learning of quantum mechanics. In particular, part of this research is focusing on misconceptions held by students. For instance, a set of misconceptions is associated with the concept of stationary…

In teaching primary teacher trainees, an awareness of the characteristic features, especially commutativity and associativity of basic operations play an important role. Owing to a deeply set automatism rooted in their primary and secondary education, teacher trainees think that such characteristics of addition are so trivial that they do not need…

Stoichiometry and related concepts are an important part of student learning in chemistry. In this interpretive-based inquiry, we investigated Thai Grade 10 and 11 students' conceptual understanding and ability to solve numerical problems for stoichiometry-related concepts. Ninety-seven participants completed a purpose-designed survey instrument…

This paper introduces various visual models for the analysis and description of learning processes. The models analyse learning on two levels: the dynamic level (as a process over time) and the functional level. Two types of model for dynamic modelling are proposed: the session trace, which documents a specific learner in a particular learning…

Describes Diagnosis for Instruction in Problem Solving (DIPS), a new line of research for science educators interested in interdisciplinary efforts and ways in which computer technology might be used to better understand how to improve science teaching. Outlines the basic architecture of DIPS in terms of instruction and research implications.…

This report describes how to improve the effectiveness of the federal role in international Science and Engineering (S&E) based on relevant policy documents and reports and a wide range of different perspectives. The contents of the book are divided into four chapters. Chapter 1, "Introduction," includes "Process for Developing…

The presentation of physics content knowledge in conjunction with the lack of examples in solving problems leads high school students to struggle with mathematical problem solving in physics courses. This paper explains the importance and necessity of having mathematical courses for all high school students. (YDS)

This paper introduces issues related to the role of intuitive knowledge in physics learning. Phenomenological primitives, which form the base level for intuitive explanations in the research, are discussed. Three primary questions are the focus of this paper: (1) What role, if any, does intuitive knowledge play in physics problem solving? (2) How…

Use of end-of-chapter textbook problems for teaching and assessing concepts in introductory physics is widespread, as is restriction of student access to the solutions. Surveys student attitudes (n=128) on access to problem solutions, sampling the enrollment in a large calculus-level course. Results confirm a definite preference for freer access…
