Intelligent tutoring system (ITS) provides learners with step-by-step problem-solving support through scaffolding. Most ITSs have been developed in the USA and incorporate American instructional strategies. How do non-American students perceive and use ITS with different native problem-solving strategies? The present study compares Stoich Tutor,…

Enactment of scientific inquiry in classroom has attracted a great attention of science educators around the world. In this study, we examined two competent teachers' (one Grade 9 chemistry teacher and one Grade 4 science teacher) enactment of scientific inquiry in selected teaching units to reveal the characteristics of enacted inquiry at…

The Advanced Placement (AP) Descriptive Chemistry Website allows users to practice chemistry problems. This study involved the redesign of the Website using worked examples to enhance learner performance. The population sample for the study includes users (students and teachers) interested in learning descriptive chemistry materials. The users…

It is complicated to design a computer simulation that adapts to students with different characteristics. This study documented cases that show how college students' prior chemistry knowledge level affected their interaction with peers and their approach to solving problems with the use of computer simulations that were designed to learn…

The objectives of this study are: (a) Evaluate science major freshman students' ability to differentiate between heat energy and temperature, after having studied the topic of thermochemistry; (b) ascertain the degree to which students resist change from the caloric to the kinetic-molecular theory; (c) study the ability to differentiate between…

Investigates the effect of Pen-Point and Powerbook computers on solving a multiple-step chemistry problem among white, Afro-American, and Hispanic students. Results suggest that the Pen-Point computer has a more positive effect on the problem- solving performance and attitude of students towards computers than the Powerbook computer. Contains 14…

Illustrates how a novel problem of chemical equilibrium based on a closely related sequence of items can facilitate students' conceptual understanding. Students were presented with a chemical reaction in equilibrium to which a reactant was added as an external effect. Three studies were conducted to assess alternative conceptions. (Author/SAH)

Investigates reasoning strategies students use in solving stoichiometric problems and explores the relation between these strategies and alternative conceptions, prior knowledge, and cognitive variables. Results show how stoichiometric relations produce conflicting situations for students leading to conceptual misunderstanding of certain concepts.…

The study examined the effect of supplementing laboratory instruction with problem solving strategy and or practical skills teaching on students' attitude toward chemistry. A total of 286 senior secondary class II students (145 males and 141 females) drawn from four local government areas in Oyo township in Oyo state, Nigeria, took part in the…

Results of a HyperCard method for assessing the performance of expert and novice high school chemistry students solving stoichiometric chemistry problems (balancing chemical equations) is reported. MANOVA results indicate significant difference between expert and novice students solving the five stoichiometric chemistry problems using…

One of the modules in the course Food Chemistry at Wageningen University (Wageningen, The Netherlands) focuses on quantitative problem-solving skills related to chemical reactions. The intended learning outcomes of this module are firstly, to be able to translate practical food chemistry related problems into mathematical equations and to solve…
