Online metacognitive skills are the real-time awareness of cognition, which can effectively promote science learning and improve performance in solving scientific problems. Therefore, it is important to enhance and diagnose students' online metacognitive skills in science education. This study aimed to evaluate ninth-grade students' online…

Assessment of problem-solving skills for preservice teachers is important in science instruction. The purpose of this study is to discover; (a) How are the characteristics of the Problem-Solving Essay Test Instrument (PSETI); (b) How is the validity based on experts assessment; (c) how are the validity and reliability based on trials. The research…

Science learning in the 21st century should develop the abilities of the students to find solutions to the problems. This task requires a set of skills called Higher Order Thinking Skills (HOTS) and innovative assessment should be designed to gauge the acquisition of these skills. Thus, this study aimed to create an innovative HOTS-based…

This paper marks the second in a series of five reports detailing the work of the Optimizing Assessment for All (OAA) project at Brookings to strengthen education systems capacity to integrate 21st century skills into teaching and learning, using assessment as a lever for changing classroom practices. Twenty-first century skills (21CS) are now…

The aim of this study was to investigate the effect of Problem-Based Learning (PBL) on undergraduate students' learning about solutions and their physical properties, and on their scientific processing skills. The quasi experimental study was carried out through non-equivalent control and comparison groups pre-post test design. The data were…

The influence of metacognition on learning and problem solving has been demonstrated, and it is becoming increasingly clear that promoting metacognitive activity can produce substantial improvements in problem solving and learning in chemistry. This article reports the development and validation of an instrument designed to evaluate students'…

Presents two exam questions and answers on the topics of stoichiometric calculations and general chemistry pressure measurement. (SL)

Explains the importance of problem solving and critical thinking for scientific literacy and discusses assessment strategies to evaluate student problem solving. (YDS)

The development and validation of a test of science problem solving skills for use in grades one through three are described. Norms (grade placement scores) for children in urban, outer-urban, and suburban areas are provided for the total score on alternate forms of the test, each of which uses two physical science problems to assess (1) the…

Presents problems on the determinations of the maximum number of "monsters" which can inhabit Loch Ness and on the pH of pure water. (SL)

THIS RESEARCH ATTEMPTED TO DEMONSTRATE THE FEASIBILITY OF DEVELOPING TEST INSTRUMENTS TO DETECT HOW LIMITED VARIABLES IN EDUCATIONAL EXPERIENCES AFFECT STUDENT BEHAVIORAL DEVELOPMENT. THE EXPERIMENTAL HYPOTHESES DEVELOPED FOR THE STUDY WERE CONCERNED WITH IDENTIFYING AND DEFINING INDIVIDUAL ABILITIES OPERATING IN THE REALM OF SCIENCE EDUCATION.…

This report describes a methodology for increasing the validity and reliability of inferences made about the problem-solving ability of science students that is based on performance on different kinds of tests. The generalizable cognitive components of problem solving that might be targeted by assessment are described, and specifications are…

Presented is a description and copy of a test manual developed to include items in the test on the basis of children's performance; each item correlated highly with performance on an external criterion. The external criterion was the Individual Competency Measures of the elementary science program Science - A Process Approach (SAPA). The test…

This study investigated the relationships among the symbolic representation of problems given to students to solve, the mental representations they use to solve the problems, and the accuracy of their solutions. Twenty eleventh-grade science students were asked to think aloud as they solved problems on the ideal gas laws. The problems were…

Multiple-choice tests were constructed for seven problem-solving skills using learning hierarchies based on expert-novice differences and refined in three phases of field testing. Includes test reliabilities (sufficient for making judgments of group performance but insufficient in single-administration for individual assessment), validity, and…
