This research that aimed to (1) produce instruments that were feasible to measure the ability to solve physics problems and nationalism, and (2) determine the quality of instruments that have been developed. This research was conducted through four stages, namely the design, preparation of tests, test trials, and preparation of valid instruments.…

The "Next Generation Science Standards" ("NGSS") have placed an emphasis on the incorporation of engineering practices into K-12 science instruction. This article details a sequence of physical science lessons that would be part of teaching matter in the second-grade classroom. The goals of these lessons are: (1) to be hands-on…

Educational leaders are faced with multiple ethical decisions every day. This article presents the Values-Issue-Action (VIA) Model as a tool for developing ethical decisions in K-12 schools. The model is presented with three scenarios from K-12 education to practice using the model into practice. The model can be used by current school leaders and…

The study was conducted to analyze the items about the ability of high school students diagram representation and obtain Item Curve Characteristic. Grid test instruments are compiled based on competencies and indicators of diagram representation which are then used to compile items. The test instrument consisted of five items and was validated by…

This article presents the results of observations and analyses of students' learning model-driven system development from two related courses taught at a university in Norway and at a university in the United States in 2015, and consequently, in an updated version in 2016. The motivation of this article is to understand and analyse how effective…

This chapter describes the importance of self-determination for transitions and supports for adults with disabilities. Self-determination is defined and its application to the disability context examined, followed by an overview of a multicomponent model to engage adults with disabilities to self-regulate problem solving to set and attain life and…

In this study it was aimed to evaluate the effects of various factors such as sample sizes, percentage of misfit items in the test and item quality (item discrimination) on item and model fit in case of misspecification of Q matrix. Data were generated in accordance with DINA model. Q matrix was specified for 4 attributes and 15 items. While data…

The study aimed to evaluate the 8th grade mathematics curriculum in Turkey, which was revised in 2016-2017 school year, and implemented from 2017-2018 school year on. In the study the Eisner's educational connoisseurship and criticism model was utilized. The participants of the study comprised 15 secondary school mathematics teachers selected by…

Many classroom-observation instruments have been developed (e.g., Gleason et al., 2017; Nava et al., 2019; Sawada et al., 2002), but a very small number of studies published in refereed journals have rigorously examined the quality of the ratings and the instrument using measurement models. For example, Gleason et al. developed a mathematics…

Contribution: This paper qualitative research delineates the thinking and behavioral patterns that reflect students' advanced level of epistemological thinking in project-based learning (PBL) activities and the associated impact factors. Background: PBL has been widely adopted in engineering education for its effectiveness in improving students'…

This Research & Development (R & D) aims to develop and produce a qualified Group Science Learning (GSL) model. The main product is the GSL model that has the following syntax: (1) Motivation and problem orientation based on Internet of things, (2) Collaborative problem-solving activities, (3) Presenting, (4) Nonroutine problem-solving,…

The ability to think mathematically includes many mental activities which involve the workings of the brain. To describe students' mathematical thinking ability, one of the efforts that can be done is to apply the mathematical problem-based learning model. It involves students to solve a problem through scientific method stages, so that students…

Mathematical thinking is an important aspect of mathematics education and, therefore, also needs to be understood by prospective teachers. Prospective teachers should have the ability to analyze and interpret students' mathematical thinking. Comparing model is one of the interpretation models from Wilson, Lee, and Hollebrands. This article will…

The purpose of this research was to determine the effects of explicit instructions on children's divergent and creative thinking. Fifty-two children were assigned to one of four groups. Two of the groups were presented a problem with a model and instructions for solving the problem first and then presented problems with no instructions/model. The…

In this study we show the models that students of administration and accounting careers built when performing an activity close to the real life, with the use of Excel. The representations and ideas exhibited by the students when they used the software are analyzed. The methodology was qualitative. The theoretical framework was the Models and…
