Use of laboratories, is one of the effective ways to learn Learning by inquiry, which can be achieved through the Laboratories in Science Teaching and Supporting The usage is reversed, with Bcombination^ denoting presenting the same experiment in the two types of laboratories and Bsequencing^ meaning thatĭifferent experiments are done in each type of laboratory. Sequencing and combination are used as we do it here in other publications, The online learning environments were created within the Go-Lab ecosystem (seeĭe Jong et al.
Used structured worksheets the virtual laboratories wereĮmbedded in an online learning environment that included All conditions followed a guided inquirybased approach. Used both hands-on and virtual laboratories in differentĬombinations. The first and second conditions used purely hands-on and purely virtual (i.e., inferring, classification, determining variables, and designing experiments). Topic of electricity and development of specific inquiry skills On middle school (seventh grade) students’ learning about the In particular, we investigated the effects of these different laboratory environments Hands-on and virtual labs in isolation or in combination toĮnhance students’ knowledge gains (measured as conceptual In the current study, we focused on the effects of using Hakca de of Mathematics and Science Education, Yildiz Technicalĭepartment of Instructional Technology, University of Twente,Įnvironments (e.g., Sullivan et al. (doing different experiments in a hands-on lab followedīy a virtual lab or vice versa) of the two laboratory Sequencing (doing the same experiment in a hands-on labĪnd then in a virtual lab or vice versa) and combination Own affordances, researchers have begun to investigate the Type of laboratory environment (hands-on or virtual) has its Laboratories have also entered the classroom. Have traditionally been used in schools, nowadays, virtual Students without practical experiences in school laboratories (Hofstein and Lunetta 2004 Hofstein and MamlokNaaman 2007). Is obvious that science cannot be taught meaningfully to Laboratories have a central role in science education, and it In the current study, no advantage was seen for either of the two This result, together with similar findings from other studies, suggests that virtualĪnd hands-on laboratories may have complementary affordances. Ourįindings indicate that using hands-on and virtual laboratories sequentially instead of in isolation gives better results for students’Īcquisition of knowledge and inquiry skills. Two different combinations on middle school (7th grade) students’ acquisition of conceptual knowledge and inquiry skills.
In this study, we compared the effect of using hands-on and virtual laboratories in isolation to Works Better for Acquiring Knowledge and Skills?Īlthough hands-on laboratory experiments are traditionally used in schools, virtual laboratories have entered today’s classrooms,ĭue to their specific affordances. Using Hands-On and Virtual Laboratories Alone or Together―Which The conclusion is not to reject H0 that the group means are equal.Journal of Science Education and Technology Equivalently our F observed (1.65) is much less than F critical (3.25).Įssentially the data shows that there is too high a probability that the difference between the groups is due to variability rather than treatment differences to reject the null hypothesis. So the probability of observing our F statistic or greater (20.5%) is much higher than than our significance level (5%). Notice the F value, P-value, and F criticalį is the observed value of the F statistic.į critical is the value of the F statistic from the F distribution with numerator df=2 and denominator df=39 where Pr(F>=F critical) =. Here is the output from the Excel Add-in with the alpha set to.
